RELATED APPLICATION

[0001] This application claims priority to U.S. Patent Application Serial No. 63/337,451 filed May 2, 2022 entitled “Requesting Service Policy at Time of Registration in a Wireless Communications System,” the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

[0002] The present disclosure relates to wireless communications, and more specifically to requesting a service policy at the time of registration.

BACKGROUND

[0003] A wireless communications system may include one or multiple network communication devices, such as base stations, which may be otherwise known as an eNodeB (eNB), a next-generation NodeB (gNB), or other suitable terminology. Each network communication device, such as a base station, may support wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE), or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system, such as time resources (e.g., symbols, slots, subslots, mini-slots, aggregated slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers). Additionally, the wireless communications system may support wireless communications across various radio access technologies (RATs) including third generation (3G) RAT, fourth generation (4G) RAT, fifth generation (5G) RAT, and other suitable RATs beyond 5G. In some cases, a wireless communications system may be a non-terrestrial network (NTN), which may support various communication devices for wireless communications in the NTN. For example, an NTN may include network entities onboard non-terrestrial vehicles such as satellites, unmanned aerial vehicles (UAV), and high-altitude platforms systems (HAPS), as well as network entities on the ground, such as gateway entities capable of transmitting and receiving over long distances. [0004] When a UE registers to a wireless communications system network, the UE can send a UE state indication message to inform the network of various information about the UE. This UE state indication message includes, for example, the UE’s operating system (OS) identity or other capability support. The network uses the UE state indication but does not provide a response to the UE.

SUMMARY

[0005] The present disclosure relates to methods, apparatuses, and systems that support requesting service policy at time of registration in a wireless communications system. A UE transmits a UE state indication message to a wireless communications system at a time of UE registration to the network. The UE state indication message is combined with a UE policy provisioning request at the time of the UE registration and allows the network to indicate support for one or more services, such as support for vehicle-to- everything (V2X) services or proximity services (ProSe). Using conventional techniques for providing the UE state indication message, the network does not transmit to the UE a response to the UE state indication. By utilizing the described techniques, the UE is able to inform a policy control function (PCF) to manage the policies for the V2X or ProSe at the time of UE registration to the network, and the network is able to provide the UE with a response indicating a successful or unsuccessful result for the PCF to manage the policies for the V2X or ProSe.

DETAILED DESCRIPTION

[0028] Implementations of requesting service policy at time of registration in a wireless communications system are described. A UE transmits a UE state indication message to a wireless communications system at a time of UE registration to the network. Registration to or with the network refers to a registration procedure performed for the UE to gain access to the core network of the wireless communications system. This registration may be done at various times, such as when the UE is powered on. The UE state indication is for the UE to provide a PCF in the network information so the PCF can provide the UE some general policies. Using conventional techniques, the UE state indication procedure includes only the one message, which is the UE state indication message that is transmitted from the UE to the network - there is no response that the network transmits to the UE in response to the UE state indication.

[0029] The techniques discussed herein allow a UE supporting one or more services, such as V2X or ProSe, to inform the PCF to manage the policies for the V2X or ProSe (e.g., provide an indication to the UE of policies supported by the network) at the time of UE registration to the network. The conventional UE state indication procedure does not provide a response to the UE state indication message, so using the conventional UE state indication procedure, if the network does not support V2x or ProSe, the UE cannot know about a successful or unsuccessful result for the PCF to manage the policies for the V2X or ProSe. Furthermore, using the conventional UE state indication procedure, if the network rejects the management of the policies for the V2X or ProSe due to some reason, the network cannot inform the UE of the rejection. Using the techniques discussed herein, the network is able to provide the UE with a response indicating a successful or unsuccessful result for the PCF to manage the policies for the V2X or ProSe. [0030] In one or more implementations, a multi-container type is used so that the UE transmits the UE State indication plus UE policy provisioning. In this situation, the network can be expected to treat these two separately and not using any timer for the procedure for UE state indication and use the timer for the UE policy provisioning. Additionally or alternatively, a new message is added to the UE state indication procedure to convey the request for V2x/ProSe policy, and the network provides information for supporting the ProSe/V2X. In such situations, the network responds to the UE state indication so the UE does not need to have a timer to evaluate whether the network supports the particular service (e.g., V2X or ProSe) by rejecting to manage the UE policy within a certain time.

[0031] Aspects of the present disclosure are described in the context of a wireless communications system. Aspects of the present disclosure are further illustrated and described with reference to device diagrams and flowcharts that relate to requesting service policy at time of registration in a wireless communications system.

[0032] FIG. 1 illustrates an example of a wireless communications system 100 that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more base stations 102, one or more UEs 104, and a core network 106. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE- Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as a NR network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network. The wireless communications system 100 may support radio access technologies beyond 5G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA), etc.

[0033] The one or more base stations 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the base stations 102 described herein may be, or include, or may be referred to as a base transceiver station, an access point, a NodeB, an eNodeB (eNB), a next-generation NodeB (gNB), a Radio Head (RH), a relay node, an integrated access and backhaul (IAB) node, or other suitable terminology. A base station 102 and a UE 104 may communicate via a communication link 108, which may be a wireless or wired connection. For example, a base station 102 and a UE 104 may perform wireless communication over a NR-Uu interface.

[0034] A base station 102 may provide a geographic coverage area 110 for which the base station 102 may support services (e.g., voice, video, packet data, messaging, broadcast, etc.) for one or more UEs 104 within the geographic coverage area. For example, a base station 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc.) according to one or multiple radio access technologies. In some implementations, a base station 102 may be moveable, such as when implemented as a gNB onboard a satellite or other non-terrestrial station (NTS) associated with a non-terrestrial network (NTN). In some implementations, different geographic coverage areas 110 associated with the same or different radio access technologies may overlap, and different geographic coverage areas 110 may be associated with different base stations 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0035] The one or more UEs 104 may be dispersed throughout a geographic region or coverage area 110 of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, a customer premise equipment (CPE), a subscriber device, or as some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, a UE 104 may be referred to as an Internet-of-Things (loT) device, an Internet-of-Everything (loE) device, or as a machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In other implementations, a UE 104 may be mobile in the wireless communications system 100, such as an earth station in motion (ESIM).

[0036] The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in FIG. 1. A UE 104 may be capable of communicating with various types of devices, such as the base stations 102, other UEs 104, or network equipment (e.g., the core network 106, a relay device, a gateway device, an integrated access and backhaul (IAB) node, a location server that implements the location management function (LMF), or other network equipment). Additionally, or alternatively, a UE 104 may support communication with other base stations 102 or UEs 104, which may act as relays in the wireless communications system 100.

[0037] A UE 104 may also support wireless communication directly with other UEs 104 over a communication link 112. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, V2X deployments, or cellular-V2X deployments, the communication link 112 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.

[0038] A base station 102 may support communications with the core network 106, or with another base station 102, or both. For example, a base station 102 may interface with the core network 106 through one or more backhaul links 114 (e.g., via an SI, N2, or other network interface). The base stations 102 may communicate with each other over the backhaul links 114 (e.g., via an X2, Xn, or another network interface). In some implementations, the base stations 102 may communicate with each other directly (e.g., between the base stations 102). In some other implementations, the base stations 102 may communicate with each other indirectly (e.g., via the core network 106). In some implementations, one or more base stations 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC). The ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as remote radio heads, smart radio heads, gateways, transmissionreception points (TRPs), and other network nodes and/or entities.

[0039] The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC), or a 5G core (5GC), which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an AMF that manages access, connection, and mobility), a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)), and a PCF that manages policies for various different services for the UEs 104 (e.g., provides policies for a public land mobile network (PLMN) to the UEs 104). In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for the one or more UEs 104 served by the one or more base stations 102 associated with the core network 106.

[0040] According to implementations, one or more of the UEs 104 and base stations 102 are operable to implement various aspects of requesting service policy at time of registration in a wireless communications system, as described herein. For instance, a UE 104 can communicate a registration request 116 that includes a pay load container, which may include a UE state indication and a request for the PCF to manage the policies for the V2X or ProSe. The base station 102 forwards the content of the pay load container, directly or indirectly, to one or more entities in the core network 106, such as the AMF and the PCF. The AMF returns, via the base station 102, a registration acceptance 118 indicating to the UE 104 that registration to the network has been accepted. The PCF returns, via the base station 102, a policy management response 120 indicating whether the PCF will manage the policies for the V2X or ProSe for the UE 104.

[0041] Although the discussions herein include reference to V2X and ProSe, analogous techniques apply for any of various other services.

[0042] Various signaling between the UE 104 and the base station 102 is discussed herein. This signaling can be any one or more of radio resource control (RRC), downlink control information (DCI), medium access control control element (MAC-CE), or the like.

[0043] When a UE 104 registers to the network, the UE 104 can send a UE state indication message in order to inform the PCF about: one or more stored UE policy section identifiers (UPSIs) including PLMN identity for the PLMN of the PCF providing the policies, and UE policy section code (UPSC) comprising a value assigned by the PCF; the UE's capability supporting access network discovery and selection policy (ANDSP); and the UE's OS identity. This information is used by the PCF to provide the UE the basic policies for the selected PLMN. The UE state indication message is transmitted during the registration to the network and is included in a UE policy container sent towards the PCF via the AMF by using the UP NAS TRANSPORT message, as discussed in 3 ^rd generation partnership project (3GPP) technical specification (TS) 24.501.

[0044] In conventional systems, when a UE 104 supports V2X or ProSe, in order to inform the PCF to manage policies for V2X or ProSe, the UE 104 may transmit the UE policy provisioning request message towards the PCF, where the PCF may reject the request by transmitting the UE policy provisioning reject message towards the UE 104. The UE policy provisioning request message and the UE policy provisioning reject message are defined in 3 GPP TS 24.587. In conventional systems, these messages are not during the UE registration.

[0045] FIG. 2 illustrates an example 200 of error codes that support requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The rejection of the UE policy provisioning request may be due to any of various causes. The example 200 illustrates a UE policy delivery service (UPDS) cause information element with 8- bit codes that give various causes for the PCF rejecting the UE policy provisioning request. For example, these causes for the PCF rejecting the UE policy provisioning request may include an unspecified rejection; a service option not supported; a service option temporarily out of order; a PH already in use; a semantically incorrect message; an invalid mandatory information; a message type non-existent or not implemented; a message type not compatible with the protocol state; an information element non-existent or not implemented; a conditional information element error; or an unspecified protocol error.

[0046] Returning to FIG. 1, since the UE 104 is not aware whether the network supports V2X or ProSe, if the request for the V2X or ProSe management is transmitted to the network at the time of registration, the network may inform the UE 104 that the message has been received and the related policies have successfully been managed.

[0047] In one or more implementations, the following occurs at the time of UE registration to the network: 1) the UE 104 sends to the PCF (via AMF) the information that is provided by the UE state indication procedure as described in 3GPP TS 24.501, and the information that is provided by the UE policy provisioning request procedure as described in 3GPP TS 24.587; 2) the network informs the UE 104 about the network capability for V2X or ProSe. By informing the UE 104 about the network capabilities for V2X or ProSe, if the UE 104 does not receive any rejection from the network, the UE 104 can assume that the request was successful.

[0048] The UE 104 can send to the PCF (via the AMF) the information that is provided by the UE state indication procedure as well as the information that is provided by the UE policy provisioning request procedure in various different manners. In one or more implementations, the UE state indication message is expanded to include requested UE policies information policies.

[0049] FIG. 3 illustrates an example of a UE state indication message 300 that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The UE state indication message 300 includes rows with information elements of procedure transaction identity (PTI), UE state indication message identity, UE policy section identifier (UPSI) list, UE policy classmark, UE OS Id, and requested UE policies. The presence column indicates whether the corresponding information element is mandatory (M) or optional (O). The format column indicates the formats for the information elements, such as value only (V), length and value where the length indicator two octets (LV-E), length and value where the length indicator is one octet (LV), type, length and value (TLV), and so forth. The length column indicates a length (e.g., in octets) of the corresponding information element.

[0050] The PTI information element includes an identifier of the procedure transaction.

[0051] The UE state indication message identity information element identifies the message 300 as a UE state indication message. This distinguishes the message 300 from other types of messages, such as a manage UE policy command message, a manage UE policy complete message, a manage UE policy command reject message, a UE policy provisioning request message, or a UE policy provisioning reject message.

[0052] The UPSI list information element includes a list of one or more UPSIs, each UPSI including a PLMN identifier for the PCF that provides policies for the UE 104, and a UE policy selection code set by the PCF that provides policies for the UE 104.

The information element 400 also includes a second octet (Octet 2) that identifies a length of requested UE policies (the length of the information element 400). The information element also includes a third octet (Octet 3) that identifies the requested UE policies. The information element also includes a fourth octet (Octet 4) that identifies the requested UE policies information element.

[0058] FIG. 5 illustrates an example of an information element 500 that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The information element 500 identifies the requested UE policies (e.g., the information element 500 is the third octet in the information element 400 of FIG. 4). The following are examples of UE policies that may be identified in the information element 500.

A UE policies for 5G ProSe Layer-2 Remote UE indicator (5P2RMI) bit may indicate whether UE policies for 5G ProSe Layer-2 Remote UE is requested. [0059] Returning to FIG. 1, at the time of registration, the UE 104 may include the expanded UE state indication message 300 of FIG. 3 in the payload container of the registration request message with the payload container type set to UE policy container (e.g., a value corresponding to UE policy container), when constructing the register request message (e.g., as defined in 3GPP TS 24.501).

[0060] Additionally or alternatively, the UE 104 can send to the PCF (via the AMF) the information that is provided by the UE state indication procedure as well as the information that is provided by the UE policy provisioning request procedure by using a UE status indication message (discussed below with reference to FIG. 6) together with the UE policy provisioning request message (discussed below with reference to FIG. 7).

[0061] FIG. 6 illustrates an example of a UE state indication message 600 that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The UE state indication message 600 includes rows with information elements of PTI, UE state indication message identity, UPSI list, UE policy classmark, UE OS Id, and requested UE policies. The presence column indicates whether the corresponding information element is mandatory (M) or optional (O). The length column indicates a length (e.g., in octets) of the corresponding information element.

[0062] The PTI information element includes an identifier of the procedure transaction.

[0063] The UE state indication message identity information element identifies the message 600 as a UE state indication message. This distinguishes the message 600 from other types of messages, such as a manage UE policy command message, a manage UE policy complete message, a manage UE policy command reject message, a UE policy provisioning request message, or a UE policy provisioning reject message.

[0064] The UPSI list information element includes a list of one or more UPSIs, each UPSI including a PLMN identifier for the PCF that provides policies for the UE 104, and a UE policy selection code set by the PCF that provides policies for the UE 104.

[0065] The UE policy classmark information element provides the network with information about whether the UE 104 supports ANDSP. [0066] The UE OS Id information element UE’s OS identity, providing the network with information about the OS of the UE 104.

[0068] FIG. 7 illustrates an example of a UE policy provisioning request message 700 that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The UE policy provisioning request message 700 includes rows with information elements of PTI, UE policy provisioning request message identity, and requested UE policies. The presence column indicates whether the corresponding information element is mandatory (M) or optional (O). The length column indicates a length (e.g., in octets) of the corresponding information element.

[0069] The PTI information element includes an identifier of the procedure transaction.

[0070] The UE policy provisioning request message identity information element identifies the message 700 as a UE policy provisioning request message. This distinguishes the message 700 from other types of messages, such as a manage UE policy command message, a manage UE policy complete message, a manage UE policy command reject message, a UE state indication message, or a UE policy provisioning reject message.

[0071] The requested UE policies information element identifies the requested UE policies. These requested UE policies are discussed above with reference to information element 500 of FIG. 5.

[0072] Additional information regarding the PTI information element and the UE state indication message identity can be found with reference to Table 7.2.1.1.1 in 3GPP TS 24.587.

[0073] Returning to FIG. 1 , at the time of registration, the UE 104 may include both the UE status indication message 600 of FIG. 6 and the UE policy provisioning request message 700 of FIG. 7 in the pay load container of the registration request message with the payload container type set to multi payloads, when constructing the register request message (e.g., as defined in 3GPP TS 24.501).

[0074] As discussed above, the network informs the UE 104 about the network capability for V2X or ProSe. In one or more implementations the network informs the UE 104 about the network capability for V2X or ProSe using a network feature support information element in the registration accept message to indicate the network support for the ProSe or V2X.

[0075] FIG. 8 illustrates an example of an information element 800 that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The information element 800 is a network feature support information element including a first octet (Octet 1) that includes an IEI that identifies the information element 800 as a network feature support information element (e.g., a 5GS network feature support information element).

[0081] FIG. 10 illustrates an example of a UE policy management procedure 1000 that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The UE policy management procedure 1000 is at the time of registration with the network. The UE policy management procedure 1000 involves the UE 104, the base station 102, an AMF 1002, and a PCF 1004.

[0082] At 1006, at the time of registration, in one or more implementations the UE 104 includes in the payload container of a registration request the pay load container type set to the value of the UE policy container and the UE state indication message 300 of FIG. 3. This UE state indication message includes, for example, a modified version of the UE state indication message containing the conventional information elements of the original UE state indication message as defined in Table D.5.4.1.1 in 3GPP TS 24.501 plus the requested UE policies information element defined in Table 8.3.2.1 of 3GPP TS 24.587.

[0083] Additionally or alternatively, the UE includes in the payload container of a registration request the payload container type set to the value of the multiple payloads, which is two.

[0084] FIG. 11 illustrates an example of payload container contents 1100 with multiple payloads that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. In the payload container contents 1100, the pay load container type is "Multiple payloads" and the number of entries is two. As illustrated, the payload container contents 1100 include two payload container entries: Payload container entry 1 and Pay load container entry 2. One of the payload container entries contains the payload container type set to the value of the UE policy container and the UE state indication message (e.g., UE state indication message 600 of FIG. 6), and the other payload container entry contains the pay load container type set to the value of the UE policy container and the UE policy provisioning request message (e.g., UE policy provisioning request message 700 of FIG. 7).

[0085] Returning to FIG. 10, the AMF 1002 receives the registration request via the base station 102 and at 1008 transparently passes content of the payload container to the PCF 1004.

[0086] At 1010, the AMF 1002 transmits a registration accept indication to the UE 104 via the base station 102. For example, the AMF 1002 transmits an indication to the base station 102 that the base station 102 is to transmit the registration accept indication to the UE 104. At the time of sending the registration accept, the network supporting the ProSe or V2X sets the support for the ProSe or V2X in the 5GS network feature support information element in the registration accept message. Upon receipt of the 5GS network feature support information element containing the indicators for ProSe or V2X, the UE 104 realizes that these features are supported by the network. Consequently, the UE 104 need not (and typically does not) receive any confirmation from the PCF 1004 unless the PCF 1004 is to reject the UE 104 policy provisioning request.

[0087] At 1012, if the PCF 1004 is to reject the UE policy provisioning request due to any of various issues (e.g., as illustrated in the example 200 of FIG. 2), the PCF 1004 may construct the UE policy provisioning reject response by including the appropriate UPDS cause value and sends it towards the UE 104 via the AMF 1002. For example, the PCF 1004 transmits a signaling indicating to the AMF 1002 to transmit an indication of the UE policy provisioning reject response to the UE 104, and the AMF 1002 transmits a signaling indicating to the base station 102 to transmit an indication of the UE policy provisioning reject response to the UE 104.

[0088] At 1014, if the PCF 1004 is to transmit the UE policies for the ProSe or V2X, the PCF may construct a manage UE policy command message including UE policy section management list information element with the UE policies. In one or more implementations, the manage UE policy command is a command requiring a response from the UE 104. The manage UE policy command message may include one or more UE policy section management list information elements, each identifying one or more instructions to be performed by the UE 104 for management of UE policy at the UE, e.g., as described in clause D.6.2 in 3GPP TS 24.501. For example, the PCF 1004 transmits a signaling indicating to the AMF 1002 to transmit the manage UE policy command message response to the UE 104, and the AMF 1002 transmits a signaling to the base station 102 to transmit an indication of the manage UE policy command message response to the UE 104.

[0089] At 1016, if all received instructions in the manage UE policy command have been successfully executed at the UE 104, the UE 104 may construct a manage UE policy complete message and transmit the manage UE policy complete message towards the PCF 1004. For example, the UE 104 transmits a signaling to the base station 102 indicating the manage UE policy complete message, the base station 102 transmits a signaling to the AMF 1002 indicating to the AMF 1002 to transmit the manage UE policy complete message to the PCF 1004, and the AMF 1002 transmits a signaling to the PCF 1004 indicating the manage UE policy complete message.

[0090] At 1018, if one or more received instructions in the manage UE policy command could not be successfully executed (e.g., a failure of execution of one or more instructions) at the UE 104, the UE 104 may construct the manage UE policy command reject message and transmit towards the PCF 1004. The manage UE policy command reject may include a UE policy section management result to identify the one or more received instructions in the manage UE policy command that could not be successfully executed. For example, the UE 104 transmits a signaling to the base station 102 indicating the manage UE policy command reject message, the base station 102 transmits a signaling to the AMF 1002 indicating to the AMF 1002 to transmit the manage UE policy command reject message to the PCF 1004 and the AMF 1002 transmits a signaling to the PCF 1004 indicating the manage UE policy command reject message.

[0091] Additionally or alternatively, in one or more implementations when the UE 104 sends the registration request at 1006 1006 with multiple pay loads, the UE 104 starts a timer. Upon expiration of the timer, if the UE 104 does not receive policy for the services (e.g., V2X or ProSe) and the UE 104 does not receive a rejection (e.g., at 1012 or 1014), the UE 104 transmits a separate message (not a registration message) with a container including a container type set to UE policy container and a UE policy provisioning request message. This policy provisioning request is a request for the V2X or ProSe policies. The network then sends (e.g., from the PCF 1004 via the AMF 1002 and the base station 102) its support for V2X and ProSe (e.g., a message analogous to the mange UE policy command message sent at 1014). This covers the situation when the multiple payloads have been used and the network support indication (e.g., in the registration accept at 1010) does not exist.

[0092] FIG. 12 illustrates an example of a block diagram 1200 of a device 1202 that supports requesting service policy at time of registration in a wireless communications system in accordance with aspects of the present disclosure. The device 1202 may be an example of a UE 104 as described herein. The device 1202 may support wireless communication and/or network signaling with one or more base stations 102, other UEs 104, network entities and devices, or any combination thereof. The device 1202 may include components for bi-directional communications including components for transmitting and receiving communications, such as a communications manager 1204, a processor 1206, a memory 1208, a receiver 1210, a transmitter 1212, and an I/O controller 1214. These components may be in electronic communication or otherwise coupled (e.g., operatively, communicatively, functionally, electronically, electrically) via one or more interfaces (e.g., buses).

[0093] The communications manager 1204, the receiver 1210, the transmitter 1212, or various combinations thereof or various components thereof may be examples of means for performing various aspects of the present disclosure as described herein. For example, the communications manager 1204, the receiver 1210, the transmitter 1212, or various combinations or components thereof may support a method for performing one or more of the functions described herein.

[0094] In some implementations, the communications manager 1204, the receiver 1210, the transmitter 1212, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry). The hardware may include a processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, a discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting a means for performing the functions described in the present disclosure. In some implementations, the processor 1206 and the memory 1208 coupled with the processor 1206 may be configured to perform one or more of the functions described herein (e.g., by executing, by the processor 1206, instructions stored in the memory 1208).

[0095] Additionally or alternatively, in some implementations, the communications manager 1204, the receiver 1210, the transmitter 1212, or various combinations or components thereof may be implemented in code (e.g., as communications management software or firmware) executed by the processor 1206. If implemented in code executed by the processor 1206, the functions of the communications manager 1204, the receiver 1210, the transmitter 1212, or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a central processing unit (CPU), an ASIC, an FPGA, or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting a means for performing the functions described in the present disclosure).

[0096] In some implementations, the communications manager 1204 may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise in cooperation with the receiver 1210, the transmitter 1212, or both. For example, the communications manager 1204 may receive information from the receiver 1210, send information to the transmitter 1212, or be integrated in combination with the receiver 1210, the transmitter 1212, or both to receive information, transmit information, or perform various other operations as described herein. Although the communications manager 1204 is illustrated as a separate component, in some implementations, one or more functions described with reference to the communications manager 1204 may be supported by or performed by the processor 1206, the memory 1208, or any combination thereof. For example, the memory 1208 may store code, which may include instructions executable by the processor 1206 to cause the device 1202 to perform various aspects of the present disclosure as described herein, or the processor 1206 and the memory 1208 may be otherwise configured to perform or support such operations. [0097] For example, the communications manager 1204 may support wireless communication and/or network signaling at a device (e.g., the device 1202, a UE) in accordance with examples as disclosed herein. The communications manager 1204 and/or other device components may be configured as or otherwise support an apparatus, such as a UE, including a transceiver; a processor coupled to the transceiver, the processor and the transceiver configured to cause the apparatus to: transmit, to a base station, a first signaling indicating a container that includes a state indication for the apparatus and a request to manage a policy for the apparatus; receive, from the base station, a second signaling indicating a registration acceptance for a wireless communication system network and a network capability; receive, from the base station, a third signaling indicating whether a PCF of the wireless communication system network will manage the policy for the apparatus.

In some implementations, the processor 1206 may be configured to operate a memory array using a memory controller. In some other implementations, a memory controller may be integrated into the processor 1206. The processor 1206 may be configured to execute computer-readable instructions stored in a memory (e.g., the memory 1208) to cause the device 1202 to perform various functions of the present disclosure.

[0106] The memory 1208 may include random access memory (RAM) and read-only memory (ROM). The memory 1208 may store computer-readable, computer-executable code including instructions that, when executed by the processor 1206 cause the device 1202 to perform various functions described herein. The code may be stored in a non-transitory computer-readable medium such as system memory or another type of memory. In some implementations, the code may not be directly executable by the processor 1206 but may cause a computer (e.g., when compiled and executed) to perform functions described herein. In some implementations, the memory 1208 may include, among other things, a basic I/O system (BIOS) which may control basic hardware or software operation such as the interaction with peripheral components or devices.

The receiver 1210 and the transmitter 1212 may communicate bi-directionally, via the one or more antennas 1216, wired, or wireless links as described herein. For example, the receiver 1210 and the transmitter 1212 may represent a wireless transceiver and may communicate bi-directionally with another wireless transceiver. The transceiver may also include a modem to modulate the packets, to provide the modulated packets to one or more antennas 1216 for transmission, and to demodulate packets received from the one or more antennas 1216.

If implemented in code executed by the processor 1306, the functions of the communications manager 1304, the receiver 1310, the transmitter 1312, or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a central processing unit (CPU), an ASIC, an FPGA, or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting a means for performing the functions described in the present disclosure).

[0113] In some implementations, the communications manager 1304 may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise in cooperation with the receiver 1310, the transmitter 1312, or both. For example, the communications manager 1304 may receive information from the receiver 1310, send information to the transmitter 1312, or be integrated in combination with the receiver 1310, the transmitter 1312, or both to receive information, transmit information, or perform various other operations as described herein. Although the communications manager 1304 is illustrated as a separate component, in some implementations, one or more functions described with reference to the communications manager 1304 may be supported by or performed by the processor 1306, the memory 1308, or any combination thereof. For example, the memory 1308 may store code, which may include instructions executable by the processor 1306 to cause the device 1302 to perform various aspects of the present disclosure as described herein, or the processor 1306 and the memory 1308 may be otherwise configured to perform or support such operations.
