[0017] According to other embodiments, a communication device, network node, computer program, and a computer program product can be provided for performing the above methods.

DETAILED DESCRIPTION

[0019] Inventive concepts will now be described more fully hereinafter with reference to the accompanying drawings, in which examples of embodiments of inventive concepts are shown. Inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of present inventive concepts to those skilled in the art. It should also be noted that these embodiments are not mutually exclusive. Components from one embodiment may be tacitly assumed to be present/used in another embodiment.

[0020] The following description presents various embodiments of the disclosed subject matter. These embodiments are presented as teaching examples and are not to be construed as limiting the scope of the disclosed subject matter. For example, certain details of the described embodiments may be modified, omitted, or expanded upon without departing from the scope of the described subject matter.

[0021] The Release-15 work item on enhanced long term evolution (“LTE”) support for aerial vehicles is based on the preceding study item whose outcome was documented in 3 ^rd generation partnership project (“3GPP”) TR 36.777. The work item aimed to specify features that can improve the efficiency and robustness of terrestrial LTE network for providing aerial connectivity services, particularly for low altitude unmanned aerial vehicles (“UAV”) also referred to herein as drones. [0022] For supporting the regulatory requirements for drone UE identification in LTE networks, Rel-15 specified a subscription based authorization method. Support of Aerial UE function is stored in the user’s subscription information in a home subscriber server (“HSS”). The HSS transfers this information to the mobility management entity (“MME”) from where it can be provided to the LTE base station (“eNB”) via the S1 application protocol (“AP”). In addition, for X2-based handover, the source eNB can include the subscription information in the X2-AP Handover Request message to the target eNB. For the intra and inter MME S1 based handover, the MME provides the subscription information to the target eNB after the handover procedure. The eNB may then combine this information with radio capability indication from the aerial UE in order to identify whether the aerial UE has been authorized to be connected to the LTE network while flying.

[0023] The flying mode detection is an important issue. The flying mode detection is also related to interference detection as the interference conditions for flying aerial UEs are different from aerial UE in terrestrial mode. For interference detection, which may also serve as input to flying mode detection, an enhancement to existing events triggering of reference signal received power (“RSRP”)/reference signal received quality (“RSRQ”)/reference signal signal-to-interference and noise ratio (“RS-SINR”) reports was introduced in LTE Rel-15. The UE may be configured to trigger an event such as A3, A4, A5, which all consider neighbor cell measurements. In such event triggers, a measurement report is triggered when multiple cells’ measured RSRPs/RSRQs/RS-SINRs are above a threshold. Another input to flying mode detection is height and optionally location and speed reporting based on height threshold. In LTE, both the RSRP triggering based on a number of triggered cells as well as the height reporting have capability signaling, which is conditionally mandatory if the subscription has the aerial authorization.

[0024] In some cases it may not be allowed that a UAV is flying in certain areas, or it may be allowed only during certain periods of time, or it may be allowed to fly within a certain area, but not to transmit when the UAV is there.

[0025] Various embodiments described herein provide operations to be performed by a UE or a network to limit capabilities of the UE based on the UE being within a limited capability zone. In some examples, a network may instruct a UE to limit its movement or frequencies used for transmission in response to detecting the UE has entered a limited capability zone. In some embodiments, a process is provided for a UE (in a drone) to acquire no-fly zone information and take appropriate actions so as to not violate the rules of a no fly zone. In some examples, this process can provide the potential advantage of the UE avoiding violation of no- fly zone rules.

[0026] FIG. 2 is a block diagram illustrating elements of a wireless device 200 (also referred to as a mobile terminal, a mobile communication terminal, a wireless communication device, a wireless terminal, mobile device, a wireless communication terminal, a user equipment (“UE”), a user equipment node/terminal/device, etc.) configured to provide wireless communication according to embodiments of inventive concepts. (Wireless device 200 may be provided, for example, as discussed below with respect to wireless device 4110 of FIG. 7, UE 4200 of FIG. 8, UEs 4491 , 4492 of FIG. 10, and UE 4530 of FIG. 11.) As shown, wireless device UE may include an antenna 207 (e.g., corresponding to antenna 4111 of FIG. 7), and transceiver circuitry 201 (also referred to as a transceiver, e.g., corresponding to interface 4114 of FIG. 7; interfaces 4205, 4209, 4211 , transmitter 4233, and receiver 4235 of FIG. 8; and radio interface 4537 of FIG. 11 ) including a transmitter and a receiver configured to provide uplink and downlink radio communications with a base station(s) (e.g., corresponding to network node 4160 of FIG. 7, also referred to as a RAN node) of a radio access network. Wireless device UE may also include processing circuitry 203 (also referred to as a processor, e.g., corresponding to processing circuitry 4120 of FIG. 7, processor 4201 of FIG. 8, and processing circuitry 4538 of FIG. 11 ) coupled to the transceiver circuitry, and memory circuitry 205 (also referred to as memory, e.g., corresponding to device readable medium 4130 of FIG. 7) coupled to the processing circuitry. The memory circuitry 205 may include computer readable program code that when executed by the processing circuitry 203 causes the processing circuitry to perform operations according to embodiments disclosed herein. According to other embodiments, processing circuitry 203 may be defined to include memory so that separate memory circuitry is not required. Wireless device UE may also include an interface (such as a user interface) coupled with processing circuitry 203, and/or wireless device UE may be incorporated in a vehicle.

[0027] As discussed herein, operations of wireless device UE may be performed by processing circuitry 203 and/or transceiver circuitry 201 . For example, processing circuitry 203 may control transceiver circuitry 201 to transmit communications through transceiver circuitry 201 over a radio interface to a radio access network node (also referred to as a base station) and/or to receive communications through transceiver circuitry 201 from a RAN node over a radio interface. Moreover, modules may be stored in memory circuitry 205, and these modules may provide instructions so that when instructions of a module are executed by processing circuitry 203, processing circuitry 203 performs respective operations (e.g., operations discussed below with respect to Example Embodiments relating to wireless devices).

[0028] In some embodiments, the wireless device 200 is included in a UAV/drone. The term drone may be used for a wireless device (such as a UE) that is associated, e.g. attached to, a drone. The term UE, drone, and wireless device may therefore be used interchangeably in this document.

[0029] FIG. 3 is a block diagram illustrating elements of a radio access network RAN node 300 (also referred to as a network node, base station, eNodeB/eNB, gNodeB/gNB, etc.) of a Radio Access Network (“RAN”) configured to provide cellular communication according to embodiments of inventive concepts. (RAN node 300 may be provided, for example, as discussed below with respect to network node 4160 of FIG. 7, base stations 4412a-c of FIG. 10, and/or base station and embodiments described herein and be withing the intended scope of this disclosure, unless otherwise noted) As shown, the RAN node may include transceiver circuitry 301 (also referred to as a transceiver, e.g., corresponding to portions of interface 4190 of FIG. 7 and/or portions of radio interface 4527 of FIG. 11 ) including a transmitter and a receiver configured to provide uplink and downlink radio communications with mobile terminals. The RAN node may include network interface circuitry 307 (also referred to as a network interface, e.g., corresponding to portions of interface 4190 of FIG. 7 and/or portions of communication interface 4526 of FIG. 11 ) configured to provide communications with other nodes (e.g., with other base stations) of the RAN and/or core network CN. The network node may also include processing circuitry 303 (also referred to as a processor, e.g., corresponding to processing circuitry 4170 of FIG. 7 and/or processing circuitry 4528 of FIG. 11 ) coupled to the transceiver circuitry, and memory circuitry 305 (also referred to as memory, e.g., corresponding to device readable medium 4180 of FIG. 7) coupled to the processing circuitry. The memory circuitry 305 may include computer readable program code that when executed by the processing circuitry 303 causes the processing circuitry to perform operations according to embodiments disclosed herein. According to other embodiments, processing circuitry 303 may be defined to include memory so that a separate memory circuitry is not required.

[0030] As discussed herein, operations of the RAN node may be performed by processing circuitry 303, network interface 307, and/or transceiver 301 . For example, processing circuitry 303 may control transceiver 301 to transmit downlink communications through transceiver 301 over a radio interface to one or more mobile terminals or mobile UEs and/or to receive uplink communications through transceiver 301 from one or more mobile terminals or mobile UEs over a radio interface. Similarly, processing circuitry 303 may control network interface 307 to transmit communications through network interface 307 to one or more other network nodes and/or to receive communications through network interface from one or more other network nodes. Moreover, modules may be stored in memory 305, and these modules may provide instructions so that when instructions of a module are executed by processing circuitry 303, processing circuitry 303 performs respective operations (e.g., operations discussed below with respect to Example Embodiments relating to RAN nodes). [0031 ] According to some other embodiments, a network node may be implemented as a core network CN node without a transceiver. In such embodiments, transmission to a wireless device UE may be initiated by the network node so that transmission to the wireless device is provided through a network node including a transceiver (e.g., through a base station or RAN node). According to embodiments where the network node is a RAN node including a transceiver, initiating transmission may include transmitting through the transceiver.

[0032] FIG. 4 is a block diagram illustrating elements of a core network CN node (e.g., an SMF node, an AMF node, etc.) of a communication network configured to provide cellular communication according to embodiments of inventive concepts. As shown, the CN node may include network interface circuitry 407 (also referred to as a network interface) configured to provide communications with other nodes of the core network and/or the radio access network RAN. The CN node may also include a processing circuitry 403 (also referred to as a processor) coupled to the network interface circuitry, and memory circuitry 405 (also referred to as memory) coupled to the processing circuitry. The memory circuitry 405 may include computer readable program code that when executed by the processing circuitry 403 causes the processing circuitry to perform operations according to embodiments disclosed herein. According to other embodiments, processing circuitry 403 may be defined to include memory so that a separate memory circuitry is not required.

[0033] As discussed herein, operations of the CN node may be performed by processing circuitry 403 and/or network interface circuitry 407. For example, processing circuitry 403 may control network interface circuitry 407 to transmit communications through network interface circuitry 407 to one or more other network nodes and/or to receive communications through network interface circuitry from one or more other network nodes. Moreover, modules may be stored in memory 405, and these modules may provide instructions so that when instructions of a module are executed by processing circuitry 403, processing circuitry 403 performs respective operations (e.g., operations discussed below with respect to Example Embodiments relating to core network nodes).

[0034] In some embodiments, a limited capability zone may be a no-fly zone. The term no-fly zone as used herein may be a geographical area with specific limitations as to when a UE can be in and/or airborne in the geographical area. The no-fly zone may include a geometrical shape which may be defined by certain coordinates. It may include one, two, or three spatial dimensions. For example, above/below a certain height, or inside/outside a 2D-shape, or within/outside a certain 3D-shape. In some situations, UEs may be allowed to fly within the no-fly zone. For example, at certain heights and/or at certain times of day/week/month/year UEs may be allowed to fly in the no-fly zone. One example of a no-fly zone includes national parks.

[0035] A no-fly zone may comprise a property indicating whether it is allowed or not allowed to transmit radio signals in the zone. For example, it may be allowed to fly within the zone, but it is not allowed to transmit radio signals within that zone. [0036] If it is disallowed to transmit radio signals in a zone, it may be limited to certain radio resources, for example to certain frequency bands, etc. Or it may be limited to certain signals. Or may be limited to transmissions of certain characteristics, e.g. transmissions are allowed given that the power of the transmission is below a certain limit, or that the duty cycle of the transmissions is below a certain limit, etc. In this sense the "no-fly zone" may be considered to be a "no-transmission zone" and may be referred to as such. Note that such a "notransmission zone" may be implemented as a "no-communication zone" where instead of it is defined so that transmissions are not allowed in particular, but instead it is more generally defines so that radio communication within the zone is not allowed (which may be referred to as "no-communication zone"), i.e. also comprising radio receptions.

[0037] A no-fly zone may comprise a time component indicating when for example the no-fly property of the zone applies. This may mean that it may be allowed to fly within the zone during certain times, but not at other times (or using opposite logic: it is not allowed to fly within the zone during certain times, but it is allowed at other times). Similarly, a time component may determine when it is allowed and not allowed to transmit radio signals in the no-fly zone.

[0038] In additional or alternative embodiments, a limited capability zone may be a frequency-sensitive zone. The term frequency-sensitive zone as used herein may be a geographical area with specific properties that make it advantageous to limit frequencies used by the UE for transmission. In some examples, a hospital, airplane, or another area with frequency-sensitive equipment may be considered a frequency-sensitive zone. In additional or alternative embodiments, a limited capability zone may be a no-transmission zone. In some examples, high security areas may be no-transmission zones.

[0039] Some of the following descriptions describe some embodiments in relation to a limited capability zone being a no-fly zone, however, similar embodiments may be directed to other types of limited capability zones (e.g., frequency-sensitive zones and no-transmission zones).

[0040] In some embodiments, a drone determines characteristics of a no-fly zone. In some examples, the UE may determine characteristics of multiple no-fly zones. The UE may determine a no-fly zone and the relevant parameters for it (e.g. times when it is not allowed to fly within the zone, or whether one is allowed to transmit or communicate in the zone, etc.) based on network signaling.

[0041] In some embodiments, the network may send characteristics of the no-fly zone to the UE using dedicated signaling. In some examples, this may be signaled using a dedicated radio resource control (“RRC”) message. For the dedicated signaling approach, the network may trigger the transmission of the no- fly zone information to a UE in response to one or more conditions being met. In some examples, the conditions include: that the UE is of a certain type (e.g., has flying capabilities); that the UE is identified as flying (e.g., not only capable of flying, but is actually flying); that a subscription associated with the UE indicates that the UE is eligible for flying; that the UE with flying capability may be in (or plans to enter) a no-fly at a certain point according to its flight plan (if this is known in advance or pre-configured); or that a UE with flying capability reports its current location and this current location is within a no-fly zone.

[0042] A network may determine information about the UE and whether the UE is actively flying based on an output of an algorithm that may use the RSRP/RSRQ and/or height reporting from the UE being above a threshold value. In LTE, both the measurement report triggering based on a number of triggered cells as well as the height reporting have capability signaling which is conditionally mandatory if the subscription has the aerial authorization. In NR it may be similar. In some examples, the network may determine that the UE may not be actually flying but, according to a flight plan associated with the UE, the UE will be at a certain location that is tagged as no-fly. [0043] In additional or alternative embodiments, characteristics of the no-fly zone are sent to the UE using broadcast signaling, such as in system information signaling.

[0044] In additional or alternative embodiments, characteristics of all the no- fly zone within a certain area (the granularity can be a city, a region, or the entire country) are pre-configured in the UE subscription and thus the UE will know them “a priori”.

[0045] As described above, the no-fly zone may only be applicable at certain times. If this is the case the network may implement this temporal aspect by providing the no-fly zone according to the applicability of the no-fly zone. For example, if the no-fly zone is applicable between time T1 and T2 the network may signal the no-fly zone to UEs during these times, but not outside these times. This may comprise that the network starts to broadcast the no-fly zone at (or around) the time T1 and stops at (or around) T2. This has the benefit that the no-fly zone will not need to explicitly indicate a time-component of when it is applicable. With dedicated signaling the network may configure for a UE the no-fly zone at time T1 and deconfigure it at time T2 (in the special case when the UE may connect to the network at sometime between T1 and T2, the network may provide the no-fly zone in response to that the UE connects to the network.

[0046] In some embodiments, the network configures the UE with a no-fly pattern that needs to be followed within a certain no-fly zone. The no-fly pattern is used to indicate to the UE the subframes within a certain system frame number (“SFN”) (or frame) in which the UE is allowed to be “on” and transmit and receive data/control signaling and in which subframes within a SFN the UE should be “off” and stop any transmission or reception. Alternatively, “on” may also mean (in addition to what state in the previous sentence) that the UE is allowed to fly and that “off” is not allowed to fly.

[0047] In additional or alternative embodiments, the network may indicate if, for a limited capability zone, it is allowed to fly within that zone (i.e. it is a no-fly zone). That may be indicated using an indication that, if set to a first value (or an indication is being present), indicates that flying within the zone is not allowed, while if set to a second value (or the indication is absent) flying within the zone is allowed. [0048] In additional or alternative embodiments, the network may indicate if, for a limited capability zone, the UE is allowed to transmit within that zone (i.e. it is a no-transmission zone). Alternatively (as per the no-communication zone definition), the network may indicate if radio communication in the zone is allowed or not.

[0049] In additional or alternative embodiments, the network may indicate if, a no-fly zone is specific to below or above a certain height. This may also have different stages of no-transmission. For example, there may be one height threshold above which UE may transmit radio signals normally. Then, there may be another zone, e.g. between two height thresholds where UE is allowed to transmit only in certain conditions. For example, send random access channel (“RACH”) preamble with only lowest or two lowest output power levels. Then, there may be height threshold under which UE is not allowed to transmit any radio signals. [0050] In additional or alternative embodiments, the network may also configure in dedicated or broadcast certain uplink resources which UE may use or may not use with certain no-fly or no-transmission zones. The network may send the no-fly zone to the UE in response to determining that the UE is in an area close to the no-fly zone. For example, in the same cell, tracking area, RAN area, etc.

[0051] In some embodiments, the UE may store the no-fly zone information and consider it applicable a certain time T after it has been received or until a certain (e.g. absolute) time T. The time T may be provided to the UE by the network as a parameter applicable for the no-fly zone.

[0052] In additional or alternative embodiments, the UE (e.g. the chipset within a device) which has acquired a no-fly zone may forward the no-fly zone information to higher layers in the device. The higher layers can in response to this take actions to avoid flying into the no-fly zone. For the case when the no-fly zone has a temporal component the UE may not take any particular action in case no-fly zone is currently not forbidden to be flying in (e.g. it is only forbidden to fly within the no-fly zone between T1 and T2 but currently the time is not between T1 and T2. [0053] In additional or alternative embodiments, the UE may not be allowed to transmit within the no-fly zone and the UE may also indicate to higher layers that this is not allowed. Higher layers in the UE may take actions to void that transmissions which would violate the rules in the zone. Further, the UE itself (e.g. the 3GPP chipset of the device) may also actively refrain from taking actions which would result in a transmission in the zone, e.g. refrain from performing transmissions, take action so that the UE would disconnect from the network, or attempt to connect to another (allowed) network resource instead.

[0054] In additional or alternative embodiments, operations described herein can be implemented in the RRC layer. The RRC layer may be implemented in a cloud environment, hence some embodiments may be applicable for cloud implementations.

Other embodiments, however, are contained within the scope of the subject matter disclosed herein, the disclosed subject matter should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art.

[0076] FIG. 7 illustrates a wireless network in accordance with some embodiments.

[0077] Although the subject matter described herein may be implemented in any appropriate type of system using any suitable components, the embodiments disclosed herein are described in relation to a wireless network, such as the example wireless network illustrated in FIG. 7. For simplicity, the wireless network of FIG. 7 only depicts network 4106, network nodes 4160 and 4160b, and WDs 4110, 4110b, and 4110c (also referred to as mobile terminals). In practice, a wireless network may further include any additional elements suitable to support communication between wireless devices or between a wireless device and another communication device, such as a landline telephone, a service provider, or any other network node or end device. Of the illustrated components, network node 4160 and wireless device (WD) 4110 are depicted with additional detail. The wireless network may provide communication and other types of services to one or more wireless devices to facilitate the wireless devices’ access to and/or use of the services provided by, or via, the wireless network.

[0078] The wireless network may comprise and/or interface with any type of communication, telecommunication, data, cellular, and/or radio network or other similar type of system. In some embodiments, the wireless network may be configured to operate according to specific standards or other types of predefined rules or procedures. Thus, particular embodiments of the wireless network may implement communication standards, such as Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), and/or other suitable 2G, 3G, 4G, or 5G standards; wireless local area network (WLAN) standards, such as the IEEE 802.11 standards; and/or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave and/or ZigBee standards.

[0079] Network 4106 may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs), packet data networks, optical networks, wide-area networks (WANs), local area networks (LANs), wireless local area networks (WLANs), wired networks, wireless networks, metropolitan area networks, and other networks to enable communication between devices.

[0080] Network node 4160 and WD 4110 comprise various components described in more detail below. These components work together in order to provide network node and/or wireless device functionality, such as providing wireless connections in a wireless network. In different embodiments, the wireless network may comprise any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations, and/or any other components or systems that may facilitate or participate in the communication of data and/or signals whether via wired or wireless connections.

[0081] As used herein, network node refers to equipment capable, configured, arranged and/or operable to communicate directly or indirectly with a wireless device and/or with other network nodes or equipment in the wireless network to enable and/or provide wireless access to the wireless device and/or to perform other functions (e.g., administration) in the wireless network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)). Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and may then also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio. Parts of a distributed radio base station may also be referred to as nodes in a distributed antenna system (DAS). Yet further examples of network nodes include multi-standard radio (MSR) equipment such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi- cell/multicast coordination entities (MCEs), core network nodes (e.g., MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (e.g., E-SMLCs), and/or MDTs. As another example, a network node may be a virtual network node as described in more detail below. More generally, however, network nodes may represent any suitable device (or group of devices) capable, configured, arranged, and/or operable to enable and/or provide a wireless device with access to the wireless network or to provide some service to a wireless device that has accessed the wireless network.

[0082] In FIG. 7, network node 4160 includes processing circuitry 4170, device readable medium 4180, interface 4190, auxiliary equipment 4184, power source 4186, power circuitry 4187, and antenna 4162. Although network node 4160 illustrated in the example wireless network of FIG. 7 may represent a device that includes the illustrated combination of hardware components, other embodiments may comprise network nodes with different combinations of components. It is to be understood that a network node comprises any suitable combination of hardware and/or software needed to perform the tasks, features, functions and methods disclosed herein. Moreover, while the components of network node 4160 are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, a network node may comprise multiple different physical components that make up a single illustrated component (e.g., device readable medium 4180 may comprise multiple separate hard drives as well as multiple RAM modules).

[0083] Similarly, network node 4160 may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each have their own respective components. In certain scenarios in which network node 4160 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeB’s. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, network node 4160 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium 4180 for the different RATs) and some components may be reused (e.g., the same antenna 4162 may be shared by the RATs). Network node 4160 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 4160, such as, for example, GSM, WCDMA, LTE, NR, WiFi, or Bluetooth wireless technologies. These wireless technologies may be integrated into the same or different chip or set of chips and other components within network node 4160.

[0084] Processing circuitry 4170 is configured to perform any determining, calculating, or similar operations (e.g., certain obtaining operations) described herein as being provided by a network node. These operations performed by processing circuitry 4170 may include processing information obtained by processing circuitry 4170 by, for example, converting the obtained information into other information, comparing the obtained information or converted information to information stored in the network node, and/or performing one or more operations based on the obtained information or converted information, and as a result of said processing making a determination.

[0085] Processing circuitry 4170 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application-specific integrated circuit, field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software and/or encoded logic operable to provide, either alone or in conjunction with other network node 4160 components, such as device readable medium 4180, network node 4160 functionality. For example, processing circuitry 4170 may execute instructions stored in device readable medium 4180 or in memory within processing circuitry 4170. Such functionality may include providing any of the various wireless features, functions, or benefits discussed herein. In some embodiments, processing circuitry 4170 may include a system on a chip (SOC).

[0086] In some embodiments, processing circuitry 4170 may include one or more of radio frequency (RF) transceiver circuitry 4172 and baseband processing circuitry 4174. In some embodiments, radio frequency (RF) transceiver circuitry 4172 and baseband processing circuitry 4174 may be on separate chips (or sets of chips), boards, or units, such as radio units and digital units. In alternative embodiments, part or all of RF transceiver circuitry 4172 and baseband processing circuitry 4174 may be on the same chip or set of chips, boards, or units [0087] In certain embodiments, some or all of the functionality described herein as being provided by a network node, base station, eNB or other such network device may be performed by processing circuitry 4170 executing instructions stored on device readable medium 4180 or memory within processing circuitry 4170. In alternative embodiments, some or all of the functionality may be provided by processing circuitry 4170 without executing instructions stored on a separate or discrete device readable medium, such as in a hard-wired manner. In any of those embodiments, whether executing instructions stored on a device readable storage medium or not, processing circuitry 4170 can be configured to perform the described functionality. The benefits provided by such functionality are not limited to processing circuitry 4170 alone or to other components of network node 4160, but are enjoyed by network node 4160 as a whole, and/or by end users and the wireless network generally.

[0088] Device readable medium 4180 may comprise any form of volatile or non-volatile computer readable memory including, without limitation, persistent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), mass storage media (for example, a hard disk), removable storage media (for example, a flash drive, a Compact Disk (CD) or a Digital Video Disk (DVD)), and/or any other volatile or non-volatile, non-transitory device readable and/or computer-executable memory devices that store information, data, and/or instructions that may be used by processing circuitry 4170. Device readable medium 4180 may store any suitable instructions, data or information, including a computer program, software, an application including one or more of logic, rules, code, tables, etc. and/or other instructions capable of being executed by processing circuitry 4170 and, utilized by network node 4160. Device readable medium 4180 may be used to store any calculations made by processing circuitry 4170 and/or any data received via interface 4190. In some embodiments, processing circuitry 4170 and device readable medium 4180 may be considered to be integrated.

[0089] Interface 4190 is used in the wired or wireless communication of signalling and/or data between network node 4160, network 4106, and/or WDs 4110. As illustrated, interface 4190 comprises port(s)/terminal(s) 4194 to send and receive data, for example to and from network 4106 over a wired connection. Interface 4190 also includes radio front end circuitry 4192 that may be coupled to, or in certain embodiments a part of, antenna 4162. Radio front end circuitry 4192 comprises filters 4198 and amplifiers 4196. Radio front end circuitry 4192 may be connected to antenna 4162 and processing circuitry 4170. Radio front end circuitry may be configured to condition signals communicated between antenna 4162 and processing circuitry 4170. Radio front end circuitry 4192 may receive digital data that is to be sent out to other network nodes or WDs via a wireless connection.

Radio front end circuitry 4192 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 4198 and/or amplifiers 4196. The radio signal may then be transmitted via antenna 4162. Similarly, when receiving data, antenna 4162 may collect radio signals which are then converted into digital data by radio front end circuitry 4192. The digital data may be passed to processing circuitry 4170. In other embodiments, the interface may comprise different components and/or different combinations of components. [0090] In certain alternative embodiments, network node 4160 may not include separate radio front end circuitry 4192, instead, processing circuitry 4170 may comprise radio front end circuitry and may be connected to antenna 4162 without separate radio front end circuitry 4192. Similarly, in some embodiments, all or some of RF transceiver circuitry 4172 may be considered a part of interface 4190. In still other embodiments, interface 4190 may include one or more ports or terminals 4194, radio front end circuitry 4192, and RF transceiver circuitry 4172, as part of a radio unit (not shown), and interface 4190 may communicate with baseband processing circuitry 4174, which is part of a digital unit (not shown).

[0091] Antenna 4162 may include one or more antennas, or antenna arrays, configured to send and/or receive wireless signals. Antenna 4162 may be coupled to radio front end circuitry 4192 and may be any type of antenna capable of transmitting and receiving data and/or signals wirelessly. In some embodiments, antenna 4162 may comprise one or more omni-directional, sector or panel antennas operable to transmit/receive radio signals between, for example, 2 GHz and 66 GHz. An omni-directional antenna may be used to transmit/receive radio signals in any direction, a sector antenna may be used to transmit/receive radio signals from devices within a particular area, and a panel antenna may be a line of sight antenna used to transmit/receive radio signals in a relatively straight line. In some instances, the use of more than one antenna may be referred to as MIMO. In certain embodiments, antenna 4162 may be separate from network node 4160 and may be connectable to network node 4160 through an interface or port.

[0092] Antenna 4162, interface 4190, and/or processing circuitry 4170 may be configured to perform any receiving operations and/or certain obtaining operations described herein as being performed by a network node. Any information, data and/or signals may be received from a wireless device, another network node and/or any other network equipment. Similarly, antenna 4162, interface 4190, and/or processing circuitry 4170 may be configured to perform any transmitting operations described herein as being performed by a network node. Any information, data and/or signals may be transmitted to a wireless device, another network node and/or any other network equipment.

[0093] Power circuitry 4187 may comprise, or be coupled to, power management circuitry and is configured to supply the components of network node 4160 with power for performing the functionality described herein. Power circuitry 4187 may receive power from power source 4186. Power source 4186 and/or power circuitry 4187 may be configured to provide power to the various components of network node 4160 in a form suitable for the respective components (e.g., at a voltage and current level needed for each respective component). Power source 4186 may either be included in, or external to, power circuitry 4187 and/or network node 4160. For example, network node 4160 may be connectable to an external power source (e.g., an electricity outlet) via an input circuitry or interface such as an electrical cable, whereby the external power source supplies power to power circuitry 4187. As a further example, power source 4186 may comprise a source of power in the form of a battery or battery pack which is connected to, or integrated in, power circuitry 4187. The battery may provide backup power should the external power source fail. Other types of power sources, such as photovoltaic devices, may also be used.

[0094] Alternative embodiments of network node 4160 may include additional components beyond those shown in FIG. 7 that may be responsible for providing certain aspects of the network node’s functionality, including any of the functionality described herein and/or any functionality necessary to support the subject matter described herein. For example, network node 4160 may include user interface equipment to allow input of information into network node 4160 and to allow output of information from network node 4160. This may allow a user to perform diagnostic, maintenance, repair, and other administrative functions for network node 4160. [0095] As used herein, wireless device (WD) refers to a device capable, configured, arranged and/or operable to communicate wirelessly with network nodes and/or other wireless devices. Unless otherwise noted, the term WD may be used interchangeably herein with user equipment (UE). Communicating wirelessly may involve transmitting and/or receiving wireless signals using electromagnetic waves, radio waves, infrared waves, and/or other types of signals suitable for conveying information through air. In some embodiments, a WD may be configured to transmit and/or receive information without direct human interaction. For instance, a WD may be designed to transmit information to a network on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the network. Examples of a WD include, but are not limited to, a smart phone, a mobile phone, a cell phone, a voice over IP (VoIP) phone, a wireless local loop phone, a desktop computer, a personal digital assistant (PDA), a wireless cameras, a gaming console or device, a music storage device, a playback appliance, a wearable terminal device, a wireless endpoint, a mobile station, a tablet, a laptop, a laptop- embedded equipment (LEE), a laptop-mounted equipment (LME), a smart device, a wireless customer-premise equipment (CPE), a vehicle-mounted wireless terminal device, etc. A WD may support device-to-device (D2D) communication, for example by implementing a 3GPP standard for sidelink communication, vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X) and may in this case be referred to as a D2D communication device. As yet another specific example, in an Internet of Things (loT) scenario, a WD may represent a machine or other device that performs monitoring and/or measurements, and transmits the results of such monitoring and/or measurements to another WD and/or a network node. The WD may in this case be a machine-to-machine (M2M) device, which may in a 3GPP context be referred to as an MTC device. As one particular example, the WD may be a UE implementing the 3GPP narrow band internet of things (NB-loT) standard. Particular examples of such machines or devices are sensors, metering devices such as power meters, industrial machinery, or home or personal appliances (e.g. refrigerators, televisions, etc.) personal wearables (e.g., watches, fitness trackers, etc.). In other scenarios, a WD may represent a vehicle or other equipment that is capable of monitoring and/or reporting on its operational status or other functions associated with its operation. A WD as described above may represent the endpoint of a wireless connection, in which case the device may be referred to as a wireless terminal. Furthermore, a WD as described above may be mobile, in which case it may also be referred to as a mobile device or a mobile terminal.

These wireless technologies may be integrated into the same or different chips or set of chips as other components within WD 4110. [0097] Antenna 4111 may include one or more antennas or antenna arrays, configured to send and/or receive wireless signals, and is connected to interface 4114. In certain alternative embodiments, antenna 4111 may be separate from WD 4110 and be connectable to WD 4110 through an interface or port. Antenna 4111 , interface 4114, and/or processing circuitry 4120 may be configured to perform any receiving or transmitting operations described herein as being performed by a WD. Any information, data and/or signals may be received from a network node and/or another WD. In some embodiments, radio front end circuitry and/or antenna 4111 may be considered an interface.

[0098] As illustrated, interface 4114 comprises radio front end circuitry 4112 and antenna 4111. Radio front end circuitry 4112 comprise one or more filters 4118 and amplifiers 4116. Radio front end circuitry 4112 is connected to antenna 4111 and processing circuitry 4120, and is configured to condition signals communicated between antenna 4111 and processing circuitry 4120. Radio front end circuitry 4112 may be coupled to or a part of antenna 4111. In some embodiments, WD 4110 may not include separate radio front end circuitry 4112; rather, processing circuitry 4120 may comprise radio front end circuitry and may be connected to antenna 4111. Similarly, in some embodiments, some or all of RF transceiver circuitry 4122 may be considered a part of interface 4114. Radio front end circuitry 4112 may receive digital data that is to be sent out to other network nodes or WDs via a wireless connection. Radio front end circuitry 4112 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 4118 and/or amplifiers 4116. The radio signal may then be transmitted via antenna 4111. Similarly, when receiving data, antenna 4111 may collect radio signals which are then converted into digital data by radio front end circuitry 4112. The digital data may be passed to processing circuitry 4120. In other embodiments, the interface may comprise different components and/or different combinations of components. [0099] Processing circuitry 4120 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application-specific integrated circuit, field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software, and/or encoded logic operable to provide, either alone or in conjunction with other WD 4110 components, such as device readable medium 4130, WD 4110 functionality. Such functionality may include providing any of the various wireless features or benefits discussed herein. For example, processing circuitry 4120 may execute instructions stored in device readable medium 4130 or in memory within processing circuitry 4120 to provide the functionality disclosed herein.

[0100] As illustrated, processing circuitry 4120 includes one or more of RF transceiver circuitry 4122, baseband processing circuitry 4124, and application processing circuitry 4126. In other embodiments, the processing circuitry may comprise different components and/or different combinations of components. In certain embodiments processing circuitry 4120 of WD 4110 may comprise a SOC. In some embodiments, RF transceiver circuitry 4122, baseband processing circuitry 4124, and application processing circuitry 4126 may be on separate chips or sets of chips. In alternative embodiments, part or all of baseband processing circuitry 4124 and application processing circuitry 4126 may be combined into one chip or set of chips, and RF transceiver circuitry 4122 may be on a separate chip or set of chips. In still alternative embodiments, part or all of RF transceiver circuitry 4122 and baseband processing circuitry 4124 may be on the same chip or set of chips, and application processing circuitry 4126 may be on a separate chip or set of chips. In yet other alternative embodiments, part or all of RF transceiver circuitry 4122, baseband processing circuitry 4124, and application processing circuitry 4126 may be combined in the same chip or set of chips. In some embodiments, RF transceiver circuitry 4122 may be a part of interface 4114. RF transceiver circuitry 4122 may condition RF signals for processing circuitry 4120.

[0101 ] In certain embodiments, some or all of the functionality described herein as being performed by a WD may be provided by processing circuitry 4120 executing instructions stored on device readable medium 4130, which in certain embodiments may be a computer-readable storage medium. In alternative embodiments, some or all of the functionality may be provided by processing circuitry 4120 without executing instructions stored on a separate or discrete device readable storage medium, such as in a hard-wired manner. In any of those particular embodiments, whether executing instructions stored on a device readable storage medium or not, processing circuitry 4120 can be configured to perform the described functionality. The benefits provided by such functionality are not limited to processing circuitry 4120 alone or to other components of WD 4110, but are enjoyed by WD 4110 as a whole, and/or by end users and the wireless network generally. [0102] Processing circuitry 4120 may be configured to perform any determining, calculating, or similar operations (e.g., certain obtaining operations) described herein as being performed by a WD. These operations, as performed by processing circuitry 4120, may include processing information obtained by processing circuitry 4120 by, for example, converting the obtained information into other information, comparing the obtained information or converted information to information stored by WD 4110, and/or performing one or more operations based on the obtained information or converted information, and as a result of said processing making a determination.

[0103] Device readable medium 4130 may be operable to store a computer program, software, an application including one or more of logic, rules, code, tables, etc. and/or other instructions capable of being executed by processing circuitry 4120.

In some embodiments, processing circuitry 4120 and device readable medium 4130 may be considered to be integrated.

[0104] User interface equipment 4132 may provide components that allow for a human user to interact with WD 4110. Such interaction may be of many forms, such as visual, audial, tactile, etc. User interface equipment 4132 may be operable to produce output to the user and to allow the user to provide input to WD 4110. The type of interaction may vary depending on the type of user interface equipment 4132 installed in WD 4110. For example, if WD 4110 is a smart phone, the interaction may be via a touch screen; if WD 4110 is a smart meter, the interaction may be through a screen that provides usage (e.g., the number of gallons used) or a speaker that provides an audible alert (e.g., if smoke is detected). User interface equipment 4132 may include input interfaces, devices and circuits, and output interfaces, devices and circuits. User interface equipment 4132 is configured to allow input of information into WD 4110, and is connected to processing circuitry 4120 to allow processing circuitry 4120 to process the input information. User interface equipment 4132 may include, for example, a microphone, a proximity or other sensor, keys/buttons, a touch display, one or more cameras, a USB port, or other input circuitry. User interface equipment 4132 is also configured to allow output of information from WD 4110, and to allow processing circuitry 4120 to output information from WD 4110. User interface equipment 4132 may include, for example, a speaker, a display, vibrating circuitry, a USB port, a headphone interface, or other output circuitry. Using one or more input and output interfaces, devices, and circuits, of user interface equipment 4132, WD 4110 may communicate with end users and/or the wireless network, and allow them to benefit from the functionality described herein.

This may comprise specialized sensors for doing measurements for various purposes, interfaces for additional types of communication such as wired communications etc. The inclusion and type of components of auxiliary equipment 4134 may vary depending on the embodiment and/or scenario.

[0106] Power source 4136 may, in some embodiments, be in the form of a battery or battery pack. Other types of power sources, such as an external power source (e.g., an electricity outlet), photovoltaic devices or power cells, may also be used. WD 4110 may further comprise power circuitry 4137 for delivering power from power source 4136 to the various parts of WD 4110 which need power from power source 4136 to carry out any functionality described or indicated herein. Power circuitry 4137 may in certain embodiments comprise power management circuitry. Power circuitry 4137 may additionally or alternatively be operable to receive power from an external power source; in which case WD 4110 may be connectable to the external power source (such as an electricity outlet) via input circuitry or an interface such as an electrical power cable. Power circuitry 4137 may also in certain embodiments be operable to deliver power from an external power source to power source 4136. This may be, for example, for the charging of power source 4136. Power circuitry 4137 may perform any formatting, converting, or other modification to the power from power source 4136 to make the power suitable for the respective components of WD 4110 to which power is supplied.

[0107] FIG. 8 illustrates a user Equipment in accordance with some embodiments.

[0108] FIG. 8 illustrates one embodiment of a UE in accordance with various aspects described herein. As used herein, a user equipment or UE may not necessarily have a user in the sense of a human user who owns and/or operates the relevant device. Instead, a UE may represent a device that is intended for sale to, or operation by, a human user but which may not, or which may not initially, be associated with a specific human user (e.g., a smart sprinkler controller).

Alternatively, a UE may represent a device that is not intended for sale to, or operation by, an end user but which may be associated with or operated for the benefit of a user (e.g., a smart power meter). UE 42200 may be any UE identified by the 3rd Generation Partnership Project (3GPP), including a NB-loT UE, a machine type communication (MTC) UE, and/or an enhanced MTC (eMTC) UE. UE 4200, as illustrated in FIG. 8, is one example of a WD configured for communication in accordance with one or more communication standards promulgated by the 3rd Generation Partnership Project (3GPP), such as 3GPP’s GSM, UMTS, LTE, and/or 5G standards. As mentioned previously, the term WD and UE may be used interchangeable. Accordingly, although FIG. 8 is a UE, the components discussed herein are equally applicable to a WD, and vice-versa.

For example, the processing circuitry 4201 may include two central processing units (CPUs). Data may be information in a form suitable for use by a computer.

[0111] In the depicted embodiment, input/output interface 4205 may be configured to provide a communication interface to an input device, output device, or input and output device. UE 4200 may be configured to use an output device via input/output interface 4205. An output device may use the same type of interface port as an input device. For example, a USB port may be used to provide input to and output from UE 4200. The output device may be a speaker, a sound card, a video card, a display, a monitor, a printer, an actuator, an emitter, a smartcard, another output device, or any combination thereof. UE 4200 may be configured to use an input device via input/output interface 4205 to allow a user to capture information into UE 4200.

The presence-sensitive display may include a capacitive or resistive touch sensor to sense input from a user. A sensor may be, for instance, an accelerometer, a gyroscope, a tilt sensor, a force sensor, a magnetometer, an optical sensor, a proximity sensor, another like sensor, or any combination thereof. For example, the input device may be an accelerometer, a magnetometer, a digital camera, a microphone, and an optical sensor.

Network 4243a may encompass wired and/or wireless networks such as a local-area network (LAN), a wide-area network (WAN), a computer network, a wireless network, a telecommunications network, another like network or any combination thereof. For example, network 4243a may comprise a Wi-Fi network. Network connection interface 4211 may be configured to include a receiver and a transmitter interface used to communicate with one or more other devices over a communication network according to one or more communication protocols, such as Ethernet, TCP/IP, SONET, ATM, or the like. Network connection interface 4211 may implement receiver and transmitter functionality appropriate to the communication network links (e.g., optical, electrical, and the like). The transmitter and receiver functions may share circuit components, software or firmware, or alternatively may be implemented separately.

[0113] RAM 4217 may be configured to interface via bus 4202 to processing circuitry 4201 to provide storage or caching of data or computer instructions during the execution of software programs such as the operating system, application programs, and device drivers. ROM 4219 may be configured to provide computer instructions or data to processing circuitry 4201. For example, ROM 4219 may be configured to store invariant low-level system code or data for basic system functions such as basic input and output (I/O), startup, or reception of keystrokes from a keyboard that are stored in a non-volatile memory. Storage medium 4221 may be configured to include memory such as RAM, ROM, programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), magnetic disks, optical disks, floppy disks, hard disks, removable cartridges, or flash drives. In one example, storage medium 4221 may be configured to include operating system 4223, application program 4225 such as a web browser application, a widget or gadget engine or another application, and data file 4227. Storage medium 4221 may store, for use by UE 4200, any of a variety of various operating systems or combinations of operating systems.

[0114] Storage medium 4221 may be configured to include a number of physical drive units, such as redundant array of independent disks (RAID), floppy disk drive, flash memory, USB flash drive, external hard disk drive, thumb drive, pen drive, key drive, high-density digital versatile disc (HD-DVD) optical disc drive, internal hard disk drive, Blu-Ray optical disc drive, holographic digital data storage (HDDS) optical disc drive, external mini-dual in-line memory module (DIMM), synchronous dynamic random access memory (SDRAM), external micro-DIMM SDRAM, smartcard memory such as a subscriber identity module or a removable user identity (SIM/RUIM) module, other memory, or any combination thereof. Storage medium 4221 may allow UE 4200 to access computer-executable instructions, application programs or the like, stored on transitory or non-transitory memory media, to off-load data, or to upload data. An article of manufacture, such as one utilizing a communication system may be tangibly embodied in storage medium 4221 , which may comprise a device readable medium.

[0115] In FIG. 8, processing circuitry 4201 may be configured to communicate with network 4243b using communication subsystem 4231 . Network 4243a and network 4243b may be the same network or networks or different network or networks. Communication subsystem 4231 may be configured to include one or more transceivers used to communicate with network 4243b. For example, communication subsystem 4231 may be configured to include one or more transceivers used to communicate with one or more remote transceivers of another device capable of wireless communication such as another WD, UE, or base station of a radio access network (RAN) according to one or more communication protocols, such as IEEE 802.11 , CDMA, WCDMA, GSM, LTE, UTRAN, WiMax, or the like.

Each transceiver may include transmitter 4233 and/or receiver 4235 to implement transmitter or receiver functionality, respectively, appropriate to the RAN links (e.g., frequency allocations and the like). Further, transmitter 4233 and receiver 4235 of each transceiver may share circuit components, software or firmware, or alternatively may be implemented separately.

Further, processing circuitry 4201 may be configured to communicate with any of such components over bus 4202. In another example, any of such components may be represented by program instructions stored in memory that when executed by processing circuitry 4201 perform the corresponding functions described herein. In another example, the functionality of any of such components may be partitioned between processing circuitry 4201 and communication subsystem 4231 . In another example, the non-computationally intensive functions of any of such components may be implemented in software or firmware and the computationally intensive functions may be implemented in hardware.

[0118] FIG. 9 illustrates a virtualization environment in accordance with some embodiments.

[0119] FIG. 9 is a schematic block diagram illustrating a virtualization environment 4300 in which functions implemented by some embodiments may be virtualized. In the present context, virtualizing means creating virtual versions of apparatuses or devices which may include virtualizing hardware platforms, storage devices and networking resources. As used herein, virtualization can be applied to a node (e.g., a virtualized base station or a virtualized radio access node) or to a device (e.g., a UE, a wireless device or any other type of communication device) or components thereof and relates to an implementation in which at least a portion of the functionality is implemented as one or more virtual components (e.g., via one or more applications, components, functions, virtual machines or containers executing on one or more physical processing nodes in one or more networks). [0120] In some embodiments, some or all of the functions described herein may be implemented as virtual components executed by one or more virtual machines implemented in one or more virtual environments 4300 hosted by one or more of hardware nodes 4330. Further, in embodiments in which the virtual node is not a radio access node or does not require radio connectivity (e.g., a core network node), then the network node may be entirely virtualized.

[0121] The functions may be implemented by one or more applications 4320 (which may alternatively be called software instances, virtual appliances, network functions, virtual nodes, virtual network functions, etc.) operative to implement some of the features, functions, and/or benefits of some of the embodiments disclosed herein. Applications 4320 are run in virtualization environment 4300 which provides hardware 4330 comprising processing circuitry 4360 and memory 4390. Memory 4390 contains instructions 4395 executable by processing circuitry 4360 whereby application 4320 is operative to provide one or more of the features, benefits, and/or functions disclosed herein.

[0122] Virtualization environment 4300, comprises general-purpose or specialpurpose network hardware devices 4330 comprising a set of one or more processors or processing circuitry 4360, which may be commercial off-the-shelf (COTS) processors, dedicated Application Specific Integrated Circuits (ASICs), or any other type of processing circuitry including digital or analog hardware components or special purpose processors. Each hardware device may comprise memory 4390-1 which may be non-persistent memory for temporarily storing instructions 4395 or software executed by processing circuitry 4360. Each hardware device may comprise one or more network interface controllers (NICs) 4370, also known as network interface cards, which include physical network interface 4380. Each hardware device may also include non-transitory, persistent, machine-readable storage media 4390-2 having stored therein software 4395 and/or instructions executable by processing circuitry 4360. Software 4395 may include any type of software including software for instantiating one or more virtualization layers 4350 (also referred to as hypervisors), software to execute virtual machines 4340 as well as software allowing it to execute functions, features and/or benefits described in relation with some embodiments described herein.

[0123] Virtual machines 4340 comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by a corresponding virtualization layer 4350 or hypervisor. Different embodiments of the instance of virtual appliance 4320 may be implemented on one or more of virtual machines 4340, and the implementations may be made in different ways.

[0124] During operation, processing circuitry 4360 executes software 4395 to instantiate the hypervisor or virtualization layer 4350, which may sometimes be referred to as a virtual machine monitor (VMM). Virtualization layer 4350 may present a virtual operating platform that appears like networking hardware to virtual machine 4340.

[0125] As shown in FIG. 9, hardware 4330 may be a standalone network node with generic or specific components. Hardware 4330 may comprise antenna 43225 and may implement some functions via virtualization. Alternatively, hardware 4330 may be part of a larger cluster of hardware (e.g. such as in a data center or customer premise equipment (CPE)) where many hardware nodes work together and are managed via management and orchestration (MANO) 43100, which, among others, oversees lifecycle management of applications 4320.

[0126] Virtualization of the hardware is in some contexts referred to as network function virtualization (NFV). NFV may be used to consolidate many network equipment types onto industry standard high volume server hardware, physical switches, and physical storage, which can be located in data centers, and customer premise equipment.

[0127] In the context of NFV, virtual machine 4340 may be a software implementation of a physical machine that runs programs as if they were executing on a physical, non-virtualized machine. Each of virtual machines 4340, and that part of hardware 4330 that executes that virtual machine, be it hardware dedicated to that virtual machine and/or hardware shared by that virtual machine with others of the virtual machines 4340, forms a separate virtual network elements (VNE).

[0128] Still in the context of NFV, Virtual Network Function (VNF) is responsible for handling specific network functions that run in one or more virtual machines 4340 on top of hardware networking infrastructure 4330 and corresponds to application 4320 in FIG. 9.

[0129] In some embodiments, one or more radio units 43200 that each include one or more transmitters 43220 and one or more receivers 43210 may be coupled to one or more antennas 43225. Radio units 43200 may communicate directly with hardware nodes 4330 via one or more appropriate network interfaces and may be used in combination with the virtual components to provide a virtual node with radio capabilities, such as a radio access node or a base station.

[0130] In some embodiments, some signalling can be effected with the use of control system 43230 which may alternatively be used for communication between the hardware nodes 4330 and radio units 43200.

[0131 ] FIG. 10 illustrates a telecommunication network connected via an intermediate network to a host computer in accordance with some embodiments. [0132] With reference to FIG. 10, in accordance with an embodiment, a communication system includes telecommunication network 4410, such as a 3GPP- type cellular network, which comprises access network 4411 , such as a radio access network, and core network 4414. Access network 4411 comprises a plurality of base stations 4412a, 4412b, 4412c, such as NBs, eNBs, gNBs or other types of wireless access points, each defining a corresponding coverage area 4413a, 4413b, 4413c. Each base station 4412a, 4412b, 4412c is connectable to core network 4414 over a wired or wireless connection 4415. A first UE 4491 located in coverage area 4413c is configured to wirelessly connect to, or be paged by, the corresponding base station 4412c. A second UE 4492 in coverage area 4413a is wirelessly connectable to the corresponding base station 4412a. While a plurality of UEs 4491 , 4492 are illustrated in this example, the disclosed embodiments are equally applicable to a situation where a sole UE is in the coverage area or where a sole UE is connecting to the corresponding base station 4412.

[0133] Telecommunication network 4410 is itself connected to host computer 4430, which may be embodied in the hardware and/or software of a standalone server, a cloud-implemented server, a distributed server or as processing resources in a server farm. Host computer 4430 may be under the ownership or control of a service provider, or may be operated by the service provider or on behalf of the service provider. Connections 4421 and 4422 between telecommunication network 4410 and host computer 4430 may extend directly from core network 4414 to host computer 4430 or may go via an optional intermediate network 4420. Intermediate network 4420 may be one of, or a combination of more than one of, a public, private or hosted network; intermediate network 4420, if any, may be a backbone network or the Internet; in particular, intermediate network 4420 may comprise two or more subnetworks (not shown). [0134] The communication system of FIG. 10 as a whole enables connectivity between the connected UEs 4491 , 4492 and host computer 4430. The connectivity may be described as an over-the-top (OTT) connection 4450. Host computer 4430 and the connected UEs 4491 , 4492 are configured to communicate data and/or signaling via OTT connection 4450, using access network 4411 , core network 4414, any intermediate network 4420 and possible further infrastructure (not shown) as intermediaries. OTT connection 4450 may be transparent in the sense that the participating communication devices through which OTT connection 4450 passes are unaware of routing of uplink and downlink communications. For example, base station 4412 may not or need not be informed about the past routing of an incoming downlink communication with data originating from host computer 4430 to be forwarded (e.g., handed over) to a connected UE 4491 . Similarly, base station 4412 need not be aware of the future routing of an outgoing uplink communication originating from the UE 4491 towards the host computer 4430.

[0135] FIG. 11 illustrates a host computer communicating via a base station with a user equipment over a partially wireless connection in accordance with some embodiments.

[0136] Example implementations, in accordance with an embodiment, of the UE, base station and host computer discussed in the preceding paragraphs will now be described with reference to FIG. 11. In communication system 4500, host computer 4510 comprises hardware 4515 including communication interface 4516 configured to set up and maintain a wired or wireless connection with an interface of a different communication device of communication system 4500. Host computer 4510 further comprises processing circuitry 4518, which may have storage and/or processing capabilities. In particular, processing circuitry 4518 may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. Host computer 4510 further comprises software 4511 , which is stored in or accessible by host computer 4510 and executable by processing circuitry 4518. Software 4511 includes host application 4512. Host application 4512 may be operable to provide a service to a remote user, such as UE 4530 connecting via OTT connection 4550 terminating at UE 4530 and host computer 4510. In providing the service to the remote user, host application 4512 may provide user data which is transmitted using OTT connection 4550. [0137] Communication system 4500 further includes base station 4520 provided in a telecommunication system and comprising hardware 4525 enabling it to communicate with host computer 4510 and with UE 4530. Hardware 4525 may include communication interface 4526 for setting up and maintaining a wired or wireless connection with an interface of a different communication device of communication system 4500, as well as radio interface 4527 for setting up and maintaining at least wireless connection 4570 with UE 4530 located in a coverage area (not shown in FIG. 11 ) served by base station 4520. Communication interface 4526 may be configured to facilitate connection 4560 to host computer 4510. Connection 4560 may be direct or it may pass through a core network (not shown in FIG. 11) of the telecommunication system and/or through one or more intermediate networks outside the telecommunication system. In the embodiment shown, hardware 4525 of base station 4520 further includes processing circuitry 4528, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. Base station 4520 further has software 4521 stored internally or accessible via an external connection.

[0138] Communication system 4500 further includes UE 4530 already referred to. Its hardware 4535 may include radio interface 4537 configured to set up and maintain wireless connection 4570 with a base station serving a coverage area in which UE 4530 is currently located. Hardware 4535 of UE 4530 further includes processing circuitry 4538, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. UE 4530 further comprises software 4531 , which is stored in or accessible by UE 4530 and executable by processing circuitry 4538. Software 4531 includes client application 4532. Client application 4532 may be operable to provide a service to a human or non-human user via UE 4530, with the support of host computer 4510. In host computer 4510, an executing host application 4512 may communicate with the executing client application 4532 via OTT connection 4550 terminating at UE 4530 and host computer 4510. In providing the service to the user, client application 4532 may receive request data from host application 4512 and provide user data in response to the request data. OTT connection 4550 may transfer both the request data and the user data. Client application 4532 may interact with the user to generate the user data that it provides.

[0139] It is noted that host computer 4510, base station 4520 and UE 4530 illustrated in FIG. 11 may be similar or identical to host computer 4430, one of base stations 4412a, 4412b, 4412c and one of UEs 4491 , 4492 of FIG. 10, respectively. This is to say, the inner workings of these entities may be as shown in FIG. 11 and independently, the surrounding network topology may be that of FIG. 10.

[0140] In FIG. 11 , OTT connection 4550 has been drawn abstractly to illustrate the communication between host computer 4510 and UE 4530 via base station 4520, without explicit reference to any intermediary devices and the precise routing of messages via these devices. Network infrastructure may determine the routing, which it may be configured to hide from UE 4530 or from the service provider operating host computer 4510, or both. While OTT connection 4550 is active, the network infrastructure may further take decisions by which it dynamically changes the routing (e.g., on the basis of load balancing consideration or reconfiguration of the network).

[0141] Wireless connection 4570 between UE 4530 and base station 4520 is in accordance with the teachings of the embodiments described throughout this disclosure. One or more of the various embodiments may improve the performance of OTT services provided to UE 4530 using OTT connection 4550, in which wireless connection 4570 forms the last segment. More precisely, the teachings of these embodiments may prevent a UE from violating rules and/or regulations associated with limited capability zones, which can improve public safety.

[0142] A measurement procedure may be provided for the purpose of monitoring data rate, latency and other factors on which the one or more embodiments improve. There may further be an optional network functionality for reconfiguring OTT connection 4550 between host computer 4510 and UE 4530, in response to variations in the measurement results. The measurement procedure and/or the network functionality for reconfiguring OTT connection 4550 may be implemented in software 4511 and hardware 4515 of host computer 4510 or in software 4531 and hardware 4535 of UE 4530, or both. In embodiments, sensors (not shown) may be deployed in or in association with communication devices through which OTT connection 4550 passes; the sensors may participate in the measurement procedure by supplying values of the monitored quantities exemplified above, or supplying values of other physical quantities from which software 4511 , 4531 may compute or estimate the monitored quantities. The reconfiguring of OTT connection 4550 may include message format, retransmission settings, preferred routing etc.; the reconfiguring need not affect base station 4520, and it may be unknown or imperceptible to base station 4520. Such procedures and functionalities may be known and practiced in the art. In certain embodiments, measurements may involve proprietary UE signaling facilitating host computer 4510’s measurements of throughput, propagation times, latency and the like. The measurements may be implemented in that software 4511 and 4531 causes messages to be transmitted, in particular empty or ‘dummy’ messages, using OTT connection 4550 while it monitors propagation times, errors etc.

[0143] Further definitions and embodiments are discussed below.

[0144] In the above-description of various embodiments of present inventive concepts, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of present inventive concepts. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which present inventive concepts belong. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0145] When an element is referred to as being "connected", "coupled", "responsive", or variants thereof to another element, it can be directly connected, coupled, or responsive to the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly connected", "directly coupled", "directly responsive", or variants thereof to another element, there are no intervening elements present. Like numbers refer to like elements throughout. Furthermore, "coupled", "connected", "responsive", or variants thereof as used herein may include wirelessly coupled, connected, or responsive. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Well-known functions or constructions may not be described in detail for brevity and/or clarity. The term "and/or" (abbreviated “/”) includes any and all combinations of one or more of the associated listed items.

[0146] It will be understood that although the terms first, second, third, etc. may be used herein to describe various elements/operations, these elements/operations should not be limited by these terms. These terms are only used to distinguish one element/operation from another element/operation. Thus a first element/operation in some embodiments could be termed a second element/operation in other embodiments without departing from the teachings of present inventive concepts. The same reference numerals or the same reference designators denote the same or similar elements throughout the specification. [0147] As used herein, the terms "comprise", "comprising", "comprises", "include", "including", "includes", "have", "has", "having", or variants thereof are open-ended, and include one or more stated features, integers, elements, steps, components or functions but does not preclude the presence or addition of one or more other features, integers, elements, steps, components, functions or groups thereof. Furthermore, as used herein, the common abbreviation "e.g.", which derives from the Latin phrase "exempli gratia," may be used to introduce or specify a general example or examples of a previously mentioned item, and is not intended to be limiting of such item. The common abbreviation "i.e.", which derives from the Latin phrase "id est," may be used to specify a particular item from a more general recitation.

[0148] Example embodiments are described herein with reference to block diagrams and/or flowchart illustrations of computer-implemented methods, apparatus (systems and/or devices) and/or computer program products. It is understood that a block of the block diagrams and/or flowchart illustrations, and combinations of blocks in the block diagrams and/or flowchart illustrations, can be implemented by computer program instructions that are performed by one or more computer circuits. These computer program instructions may be provided to a processor circuit of a general purpose computer circuit, special purpose computer circuit, and/or other programmable data processing circuit to produce a machine, such that the instructions, which execute via the processor of the computer and/or other programmable data processing apparatus, transform and control transistors, values stored in memory locations, and other hardware components within such circuitry to implement the functions/acts specified in the block diagrams and/or flowchart block or blocks, and thereby create means (functionality) and/or structure for implementing the functions/acts specified in the block diagrams and/or flowchart block(s).

[0149] These computer program instructions may also be stored in a tangible computer-readable medium that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable medium produce an article of manufacture including instructions which implement the functions/acts specified in the block diagrams and/or flowchart block or blocks. Accordingly, embodiments of present inventive concepts may be embodied in hardware and/or in software (including firmware, resident software, micro-code, etc.) that runs on a processor such as a digital signal processor, which may collectively be referred to as "circuitry," "a module" or variants thereof.

[0150] It should also be noted that in some alternate implementations, the functions/acts noted in the blocks may occur out of the order noted in the flowcharts. For example, two blocks shown in succession may in fact be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functional ity/acts involved. Moreover, the functionality of a given block of the flowcharts and/or block diagrams may be separated into multiple blocks and/or the functionality of two or more blocks of the flowcharts and/or block diagrams may be at least partially integrated. Finally, other blocks may be added/inserted between the blocks that are illustrated, and/or blocks/operations may be omitted without departing from the scope of inventive concepts. Moreover, although some of the diagrams include arrows on communication paths to show a primary direction of communication, it is to be understood that communication may occur in the opposite direction to the depicted arrows.

[0151 ] Many variations and modifications can be made to the embodiments without substantially departing from the principles of the present inventive concepts.
