IN WIRELESS DEVICES

TECHNICAL FIELD

[0001] This disclosure relates generally to the field of wireless communications, and in particular, to wireless device location identification.

BACKGROUND ART

[0002] Given the advent of applications and services directed to advertisements, marketing opportunities, user navigation, and social networking, it has become increasingly important to accurately determine the location or position of wireless devices.

[0003] Typically, operating systems (OS) of wireless devices employ a centralized entity (i.e., singular location manager) that controls and manages various location information providers/sensors as well as distributes location information to requesting applications/clients that are registered for location services. Recently, however, the use of distributed location managers/entities have been proposed in an attempt to alleviate processing workloads associated with a single location manager.

[0004] With this said, it will be appreciated that different location information providers/sensors may have different power consumption implications that could potentially result in suboptimal performance of the wireless device.

DETAILED DESCRIPTION

[0008] In the description that follows, like components have been given the same reference numerals, regardless of whether they are shown in different embodiments. To illustrate an embodiment(s) of the present disclosure in a clear and concise manner, the drawings may not necessarily be to scale and certain features may be shown in somewhat schematic form. Features that are described and/or illustrated with respect to one embodiment may be used in the same way or in a similar way in one or more other embodiments and/or in combination with or instead of the features of the other embodiments.

[0009] In accordance with various embodiments of this disclosure, what is proposed is a wireless device distributed location management system and method that optimizes the allocation and distribution of resources in providing location services by enabling communications between a main location processing entity and an auxiliary location processing entity and the dynamic evaluation of associated resources.

[0010] For example, in one embodiment, a system for a wireless device having location servicing capabilities is presented that includes a first location processing entity configured to manage one or more first client applications associated with the first location processing entity and manage one or more first location providers associated with the first location processing entity, the first client applications configured to initiate location service requests and the first location providers configured to perform location service operations; a second location processing entity configured to manage one or more second client applications associated with the second location processing entity, and manage one or more second location providers associated with the second location processing entity, the second client applications configured to initiate location service requests and the second location providers configured to perform location service operations; and a communications facility configured to accommodate communications between the first location processing entity and the second location processing entity. The second location processing entity reports the capabilities of the second location providers to the first location processing entity via the communications facility, and, in response to receiving a location service request, the first location processing entity evaluates capabilities of the first location providers and the reported capabilities of the second location providers to select one of the first or second location providers that optimize location service performance.

[0011] In another embodiment, a method of managing a wireless device having location servicing capabilities, is presented that includes managing, by a first location processing entity, one or more first client applications associated with the first location processing entity, the first client applications configured to initiate location service requests; managing, by the first location processing entity, one or more first location providers associated with the first location processing entity, the first location providers configured to perform location service operations; managing, by a second location processing entity, one or more second client applications associated with the second location processing entity, the second client applications configured to initiate location service requests; managing, by the second location processing entity, one or more second location providers associated with the second location processing entity, the second location providers configured to perform location service operations; and accommodating, via a communications facility, communications between the first location processing entity and the second location processing entity. The second location processing entity reports the capabilities of the second location providers to the first location processing entity via the communications facility, and, in response to receiving a location service request, the first location processing entity evaluates capabilities of the first location providers and the reported capabilities of the second location providers to select one of the first or second location providers that optimize location service performance.

[0012] These and other features and characteristics, as well as the methods of operation and functions of the related elements of structure and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of claims. As used in the specification and in the claims, the singular form of "a", "an", and "the" include plural referents unless the context clearly dictates otherwise.

[0013] The disclosed embodiments are directed a wireless device distributed location management system and method that optimizes the allocation and distribution of resources in providing location services. In particular, FIG. 1 depicts a non-limiting example of distributed location management system 100 corresponding to wireless device 150, in accordance with various aspects and principles of the present disclosure.

[0014] As used herein, the term "wireless device" refers to any electronic device that may communicate with other devices via wireless signals. Such devices may comprise, for example, a laptop, mobile device, cellular/smartphone, gaming device, tablet computer, a wireless-enabled patient monitoring device, personal communication system (PCS) device, personal digital assistant (PDA), personal audio device (PAD), portable navigational device, and/or any other electronic wireless-enabled device configured to receive a wireless signal. It may also include relatively stationary devices such as desktop computers with wireless capabilities. Such wireless devices may communicate via any number of wireless communication protocols, examples of which are described below.

[0015] As depicted in FIG. 1, system 100 employs a distributed location management architecture which is functionally/logically partitioned into Primary Location Subsystem 110 and Secondary Location Subsystem 120. As such, Primary Location Subsystem 110 and Secondary Location Subsystem 120 may be partitioned by a variety of schemes, such as, for example, employing different processors, different OSs, different memories, or any other suitable partitioning scheme.

[0016] As illustrated, Primary Location Subsystem 110 includes Primary Location Manager (PLM) entity 112, one or more location clients 114A, 114B, 114C that are communicatively coupled to PLM entity 112, and one or more location providers (LPs) 116A, 116B that are also communicatively coupled to PLM entity 112. The number of location clients and LPs depicted is not, in any way, intended to be limiting. PLM entity 112 is configured to control and manage the various location providers/sensors 116A, 116B and distribute location information to location clients 114A, 114B, 114C that are registered for location services. PLM entity 112 may comprise an application processor as well operate within the OS domain of wireless device 150.

[0017] Location clients 114A, 114B, 114C represent entities/applications/modules that initiate requests to PLM 112 for location services in an effort to identify the location of wireless device 150. The number of location clients is not, in any way, intended to be limiting. The initiated requests may be accompanied by a set of characteristic threshold requirements, i.e., Quality of Location Services (QoLS) parameters, that may include, for example, power consumption requirements, location resolution/accuracy levels, location data periodicity, location coverage areas, etc. Such entities may take the form of user- applications, OS location services, IT-based applications, etc.

[0018] Location providers (LPs) 116A, 116B represent entities that are configured to perform location services sessions to produce location data, under the direction of PLM 112. The number of LPs depicted is not, in any way, intended to be limiting. Selection and direction of any particular LP may be based on the LP's capabilities to perform the location services sessions in accordance with the QoLS parameters, as specified by the clients' 114A, 114B, and/or 114C requests. Such entities may take the form of global-navigation- satellite/global positioning system modules, e.g., GNSS, GPS, GLONASS, Galileo, COMPASS, BEIDOU, etc., as well as wireless communication modules capable of providing location/position data and indoor position data, such as, Wi-Fi, WiMax, WWAN, WLAN, WPAN, Bluetooth, GSM, CDMA, GPRS, 3G or 4G, LTE, Wireless USB, IEEE 802.11x standard, etc.

[0019] Similarly, Secondary Location Subsystem 120 includes Secondary Location Manager (SLM) entity 122, one or more location clients 124A, 124B that are communicatively coupled to SLM entity 122, and one or more location providers (LPs) 126A, 126B, 126C that are also communicatively coupled to SLM entity 122. SLM entity 112 is configured to control and manage the various location providers/sensors 126A, 126B and distribute location information to location clients 124A, 124B, 124C that are registered for location services. SLM entity 122 is designed as a dedicated off-load engine to alleviate the workload of PLM 112 in location service tasking. As such, SLM entity 122 may take the form of an auxiliary processing unit, an embedded processor, or virtual processor and may operate under a different OS or, alternatively, not employ any OS.

[0020] Like the PLM-associated clients, location clients 124A, 124B, represent entities/applications/modules that initiate requests to SLM 122 for location services in an effort to identify the location of wireless device 150. The number of location clients depicted is not, in any way, intended to be limiting. As noted above, the initiated requests may be accompanied by a set of characteristic threshold requirements, i.e., Quality of Location Services (QoLS) parameters, that may include, for example, power consumption requirements, location resolution/accuracy levels, location data periodicity, location coverage areas, etc. Such entities may take the form of user-applications, OS location services, IT-based applications, etc.

[0021] Moreover, location providers (LPs) 126A, 126B, 126C represent entities that are configured to perform location services sessions to produce location data, under the direction of SLM 122. The number of LPs depicted is not, in any way, intended to be limiting. Selection and direction of any particular LP may be based on the LP's capabilities to perform the location services sessions in accordance with the QoLS parameters, as specified by the clients' 124A and/or 124B requests. As noted above, such entities may take the form of global-navigation-satellite/global positioning system modules, e.g., GNSS, GPS, GLONASS, Galileo, COMPASS, BEIDOU, etc., as well as wireless communication modules capable of providing location/position data and indoor position data, such as, Wi-Fi, WiMax, WWAN, WLAN, WPAN, Bluetooth, GSM, CDMA, GPRS, 3G or 4G, LTE, Wireless USB, IEEE 802. llx standard, etc.

[0022] As depicted in FIG. 1, Secondary Location Subsystem 120 of wireless device 150 communicates with Primary Location Subsystem 110 via communications facility 140. Communications facility 140 enables Secondary Location Subsystem 120 to advertise, publish, or otherwise report its current location capabilities or complementary location capabilities to Primary Location Subsystem 110 and enables the PLM to control, send commands, and query for information or data from the SLM or its associated providers. In particular, communications facility 140 communicates such capability profiles from SLM entity 122 (or its associated OS) to PLM entity 112 (or its associated OS). As such, communications facility 140 may be embodied as a common application programming interface (API), a messaging protocol, a driver interface, or any other suitable communications interface mechanism.

[0023] As noted above, by virtue of the disclosed configuration, SLM entity 122 of Secondary Location Subsystem 120 may advertise to PLM entity 112 of Primary Location Subsystem 110 of its current location/complementary location capability profiles. SLM entity 122 may advertise such capabilities each time there is a change in status, such as, registering for location services, deregistering for location services, activation of LP to commence session, client request to terminate session, etc.

[0024] Moreover the capabilities profile information may include what location services sessions are currently being performed by Secondary Location Subsystem 120 as well as to what QoLS levels the sessions are being performed. The advertising or publishing of such profile information, via communications facility 140, enables PLM entity 112 to dynamically make an informed determination as to which of the LPs, whether being associated with PLM 112 or SLM 122, would be optimal in performing a requested location services session given the prescribed QoLS requirements. [0025] To this end, PLM entity 112 may be further configured with a table, listing, or other suitable data structure construct that chronicles the LP capabilities. The table or listing may include the SLM-associated LP capability profiles, as updated and advertised to PLM entity 112 by the complementary location information provided via communications facility 140, as well as the PLM-associated LP capability profiles managed by PLM 112. The LP capability profiles may be represented in terms of the LP's ability to perform location services at certain QoLs levels and the resource costs associated with employing the LP. For example, in a non-limiting embodiment, the listing of LP capability profiles may be chronicled by PLM entity 112 in LP capabilities table having the form presented by Table I, as shown below.

TABLE I

[0026] For both PLM- and SLM-associated LPs, Table I indicates what QoLS levels each LP is able to operate in performing its location services session, whether the LP is currently active in performing a session, as well as the resource costs associated with each LP in performing such services. The resource costs may be based on the power consumption of each LP as well as the current activity status of the LP. For example, an inactive LP may require a high power level to activate and satisfy a new location services session request, thereby resulting in a high resource cost. However, if that same LP is currently active with an ongoing session, the additional power level required to "piggyback" on the ongoing session to satisfy the new location services session request may be low, thereby resulting in a low resource cost.

[0027] Alternatively, or in addition to, PLM entity 112 may be configured to periodically query or poll, via communications facility 140 or other suitable facility, the SLM-associated and PLM-associated LPs for their capabilities and services during the PLM entity 112 decision-making/selection process. This polling feature may complement operations, as LPs may actively advertise their capabilities during run-time, and PLM entity 112 may then store that information for later-use, when it needs to select an LP in order to comply with client- request or other changes in the system.

[0028] Armed with the capabilities profile information chronicled by the LP capabilities table, PLM entity 112 may dynamically make an informed determination as to which LP to select in order to optimize the performance of a requested location services session in view of the prescribed QoLS requirements and LP resource costs. For example, PLM entity 112 may optimize location services performance by selecting, for a particular location services scenario, the LP that requires the minimum power levels while still sufficiently satisfying the QoLS requirements associated with the location services request.

[0029] With this said, FIG. 2 depicts a flow diagram generically depicting process 200 which dynamically manages distributed location manager entities, in accordance with various aspects and principles of the present disclosure. Initially, at block 202, process 200 reflects a client requesting location services having a set of specified (QoLS) parameters. For the purposes of illustrating the management, direction, and performance of location service interactions between Primary Location Subsystem 110 and Secondary Location Subsystem 120, at this stage, the requesting client may be associated with PLM entity 112 (e.g., clients 114A, 114B, or 114C) or the requesting client may be associated with SLM entity 122 (e.g., clients 124A or 124B). It should be understood that this description is generalized to be tractable and is not intended to be limiting in any way. As such, in practice, the actual implementation may directly specify an SLM-associated client or a PLM-associated client. Moreover, as discussed above, the QoLS parameters requested by the client, whether initiated by an SLM-associated client or PLM-associated client, may include, for example, power consumption requirements, location resolution/accuracy levels, location information periodicity, location coverage areas, etc.

[0030] So, at block 204, process 200 determines whether the requesting client is an SLM-associated client or PLM-associated client. If the client is associated with SLM 122 (i.e., YES at block 204), then process 200 advances to block 206, where SLM entity 122 selects an SLM-associated location provider (LP) that has previously registered with SLM entity 122 as having the capabilities and resources to satisfy the prescribed QoLS parameters (e.g., LPs 126A, 126B, or 126C) included in the client request. At block 208, SLM entity 122 directs the selected SLM-associated LP (e.g., LPs 126A, 126B, or 126C) to perform a location services session to produce the location data in accordance with the requirements specified by the prescribed QoLS parameters.

[0031] At block 210, SLM entity 122 updates the current location capability profile indicating the current QoLS capabilities that are potentially available as well as the complementary location capability profile indicating what QoLS parameters are being employed in current location services session that may not impose additional power requirements. For example, SLM entity 122 may update the complementary location capability profile to indicate that one of its LPs, such as, for example, LP 126A, is currently conducting a location services session having a medium level power consumption threshold requirement and a medium level accuracy requirement.

[0032] Then, at block 212, SLM entity 122 advertises, publishes, or otherwise reports the updated current and complementary location profiles to PLM entity 112. As noted above, such information is received and chronicled by PLM 112 in the form of an LP capabilities table, listing, or other construct (e.g., see Table I above).

[0033] Process 200 also checks whether the current location services session is ongoing, at block 213. If so, process 200 loops back to block 210, in order for SLM entity 122 to update current and complementary location profiles and then, at block 212, SLM entity 122 advertises or reports the updated current and complementary location profiles to PLM entity 112.

[0034] Returning back to block 204, if process 200 determines that the requesting client is a PLM-associated client (i.e., NO at block 204), such as, for example, client 114A, 114B, or 114C, PLM entity 112 checks the LP capabilities table, at block 214. As discussed above, the table chronicles both, the latest advertised SLM-associated LP complementary location capability profile as well as the PLM-associated LP capability profile. Then, at block 216, process 200 provides that PLM entity 112 evaluates the capabilities of the PLM- & SLM- associated LPs in an effort to select the LP that optimizes the performance of the requested location services session in view of the prescribed QoLS requirements and LP resource costs. Finally, at block 218, PLM entity 112 directs the selected LP to conduct location services session and produce the location data

[0035] In this manner, the disclosed process not only makes PLM 112 aware of SLM 122 status and activities, it also facilitates the dynamic evaluation of both PLM- and SLM- associated LP capabilities to select the LP that optimizes the performance of a requested location services session in view of the prescribed QoLS requirements and LP resource costs. That is, by virtue of the disclosed process, PLM 112 may select an inactive PLM-associated LP, an inactive SLM-associated LP, an active PLM-associated LP to "piggyback" on an ongoing session, or an active SLM-associated LP to "piggyback" on an ongoing session, as long as the selected LP optimizes the performance of the requested session by sufficiently satisfying the prescribed QoLS requirements while minimizing LP resource costs.

[0036] By way of illustration, FIG. 3 depicts a flow diagram illustrating an exemplary implementation 300 based on process 200 disclosed above. Exemplary implementation 300 commences at block 302 where SLM-associated client 124A requests location service with high accuracy and high power QoLS parameter requirements. At block 304, SLM entity 122 selects LP 126C based on its registered capabilities and ability to handle the high level request and, at block 306, SLM entity 122 directs LP 126C to conduct the requested location service session and produce the corresponding location data. At block 308, SLM entity 122 updates its complementary location capability profile to reflect the session activity, status, and resource costs and, at block 310, SLM 122 advertises the updated profile to PLM entity 112, where PLM entity 112 chronicles the updated profile in its LP capabilities table.

[0037] Subsequently, at block 312, PLM-associated client 114A requests location service with low accuracy, low power QoLS parameter requirements. At block 314, PLM entity 112 refers to its LP capabilities table and evaluates all LPs to determine which LP optimizes the performance of the requested location services session in view of the prescribed QoLS requirements and LP resource costs. In this example, based on the ongoing high accuracy/high power location service session performed by SLM-associated LP 126C and the determination that the resource costs in employing LP 126C to perform the newly- requested low power/low accuracy session by piggybacking on the ongoing session would be minimal, PLM entity 112 selects LP 126C as the optimal LP. And, at block 318, PLM entity 122 initiates a request to SLM entity 122 to direct LP 126C to conduct the newly-requested location service session and produce the corresponding location data.

[0038] Subsequently, at block 320, SLM-associated client 124A makes a request to SLM entity 122 to terminate its previously-requested location service and, at block 322, SLM entity 122 updates its complementary location capability profile to reflect the termination request and advertises the same to PLM entity 122. PLM entity 122 chronicles the termination request in its LP capabilities table and, at block 324, again evaluates all LPs to determine which LP optimizes the performance of the requested location services session in view of the termination request, the prescribed QoLS requirements associated with the client 114A request, and prevailing LP resource costs. In this example, PLM entity 112 selects PLM-associated LP 116A and directs this LP to intervene and conduct the location service session requested by client 114A and produce the corresponding location data.

[0039] Then, at block 328, PLM entity 112 initiates a message to SLM entity 122 acknowledging that it is acceptable to deactivate SLM-associated LP 126C from continuing to conduct location services. Finally, at block 330, SLM entity 122 directs LP 126C to discontinue performance of location services.

[0040] It should be appreciated that exemplary implementation 300, highlights some of the aspects and principles of the present disclosure and, in particular, dynamic evaluation of both PLM- and SLM-associated LP capabilities by PLM 112 to select the LP that optimizes the performance of a requested location services session in view of the prescribed QoLS requirements and LP resource costs.

[0089] Having thus described the basic concepts, it will be rather apparent to those skilled in the art after reading this detailed disclosure that the foregoing detailed disclosure is intended to be presented by way of example only and is not limiting. Various alterations, improvements, and modifications will occur and are intended to those skilled in the art, though not expressly stated herein. These alterations, improvements, and modifications are intended to be suggested by this disclosure, and are within the spirit and scope of the exemplary aspects of this disclosure.

[0090] Moreover, certain terminology has been used to describe embodiments of the present disclosure. For example, the terms "one embodiment," "an embodiment," and/or "some embodiments" mean that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Therefore, it is emphasized and should be appreciated that two or more references to "an embodiment" or "one embodiment" or "an alternative embodiment" in various portions of this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined as suitable in one or more embodiments of the present disclosure. In addition, the term "logic" is representative of hardware, firmware, software (or any combination thereof) to perform one or more functions. For instance, examples of "hardware" include, but are not limited to, an integrated circuit, a finite state machine, or even combinatorial logic. The integrated circuit may take the form of a processor such as a microprocessor, an application specific integrated circuit, a digital signal processor, a micro-controller, or the like.

[0091] Furthermore, the recited order of processing elements or sequences, or the use of numbers, letters, or other designations therefore, is not intended to limit the claimed processes and methods to any order except as can be specified in the claims. Although the above disclosure discusses through various examples what is currently considered to be a variety of useful aspects of the disclosure, it is to be understood that such detail is solely for that purpose, and that the appended claims are not limited to the disclosed aspects, but, on the contrary, are intended to cover modifications and equivalent arrangements that are within the spirit and scope of the disclosed aspects.

[0092] Similarly, it should be appreciated that in the foregoing description of embodiments of the present disclosure, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure aiding in the understanding of one or more of the various inventive aspects. This method of disclosure, however, is not to be interpreted as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment. Thus, the claims following the detailed description are hereby expressly incorporated into this detailed description.
