Description
METHODS AND APPARATUS FOR HANDLING REGULATORY PRIORITIZED SERVICES IN NON-ALLOWED AREA IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure claims the priority benefit of Indian Patent Application No. 202421039732, filed 21 May 2024, the content of which herein being incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to handling regulatory prioritized services in a non-allowed area in mobile communications.BACKGROUND
[0003] In wireless communications such as mobile communications under the current 3rd Generation Partnership Project (3GPP) specification, if an Access and Management Function (AMF) of a network determines that a user equipment (UE) is in a non-allowed area or is not in an allowed area as specified in subclause 5.3.5 of the 3GPP technical specification (TS) 24.501, and if a service type information element (IE) in a SERVICE REQUEST message sent by the UE is set to “high priority access” and service area restrictions for high priority access are allowed based on operator policy or regional / national regulations, or set to “signaling” or “data” , then the AMF is to send a SERVICE REJECT message with a 5th Generation Mobility Management (5GMM) clause value set to #28, indicating “Restricted service area. ” Otherwise, if the service type IE in the SERVICE REQUEST message is set to “high priority access” and service area restrictions for high priority access are not allowed based on operator policy or regional / national regulations, or set to “mobile terminated services” , “emergency service” , “emergency services fallback” , or “elevated signaling” , then the AMF is to continue the process as specified in subclause 5.6.1.4 in the 3GPP TS 24.501, unless for other reasons the service request cannot be accepted.
[0004] However, when the network can reject the procedure with cause #28 for high priority access as well, the UE is allowed to perform service request (s) or mobility registration update (MRU) when the UE is in a non-allowed area or is not in an allowed area for high priority access. As such, the network would keep rejecting the procedure with cause #28 and would end up in a loop of rejections over and over. Currently, at the time of the present disclosure, there is no solution to avoid such a loop. Therefore, there is a need for a solution of handling regulatory prioritized services in a non-allowed area in mobile communications.SUMMARY
[0005] The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits, and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.
[0006] An objective of the present disclosure is to propose solutions or schemes that address the issue (s) described herein. More specifically, various schemes proposed in the present disclosure are believed to provide solutions pertaining to handling regulatory prioritized services in a non-allowed area in mobile communications. It is believed that implementations of one or more of the schemes proposed herein may address or otherwise alleviate the issues described above.
[0007] In one aspect, a method may involve a UE transmitting a service request message to a network with a service type IE set to “high priority access” . The method may also involve the UE receiving a reject message from the network with a cause indicating “restricted service area” . The method may further involve the UE, responsive to the receiving, performing either or both of the following: (a) refraining from performing a registration procedure or a service request procedure for a high priority access until the UE enters an allowed area or leaves a non-allowed area; and (b) refraining from responding to paging or notification except for one or more emergency services.
[0008] In another aspect, a method may involve a network receiving a service request message from a UE with a service type IE set to “high priority access” . The method may further involve the network transmitting a reject message to the UE with a cause indicating “restricted service area” to result in the UE performing either or both of the following: (a) refraining from performing a registration procedure or a service request procedure for a high priority access until the UE enters an allowed area or leaves a non-allowed area; and (b) refraining from responding to paging or notification except for one or more emergency services.
[0009] In yet another aspect, a method may involve a UE receiving an indication from a network about location information related to where a high priority access is not allowed due to a service area restriction. The method may further involve the UE, responsive to the receiving, performing either or both of the following: (a) refraining from performing a registration procedure or a service request procedure for a high priority access until the UE enters an allowed area or leaves a non-allowed area; and (b) refraining from responding to paging or notification except for one or more emergency services.
[0010] It is noteworthy that, although the description provided herein may be in the context of certain radio access technologies, networks, and network topologies such as 5th Generation (5G) NR / Beyond Fifth-Generation (B5G) mobile communications, the proposed concepts, schemes and any variation (s) / derivative (s) thereof may be implemented in, for and by other types of radio access technologies, networks and network topologies such as, for example and without limitation, 4G / Long-Term Evolution (LTE) , LTE-Advanced, LTE-Advanced Pro, Internet-of-Things (IoT) , Narrow Band Internet of Things (NB-IoT) , Industrial Internet of Things (IIoT) , vehicle-to-everything (V2X) , and non-terrestrial network (NTN) communications.

[0017] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0018] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to handling regulatory prioritized services in a non-allowed area in mobile communications. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0019] FIG. 1 illustrates an example network environment 100 in which various solutions and schemes in accordance with the present disclosure may be implemented. FIG. 2 ~ FIG. 5 illustrate examples of implementation of various proposed schemes in network environment 100 in accordance with the present disclosure. The following description of various proposed schemes is provided with reference to FIG. 1 ~ FIG. 5.
[0020] Referring to FIG. 1, network environment 100 may involve a UE 110, such as a mobile device or smartphone, in wireless communication with a wireless network 120 as part of a communication network. The wireless network 120 may be one or more public land mobile networks (PLMNs) including 5G / NR domain, 4G / LTE domain, and 2nd Generation / 3rd Generation (2G / 3G) domain. UE 110 may initially be in wireless communication with wireless network 120 via a base station or network node 125 (e.g., an eNB, gNB or transmit-receive point (TRP) ) . In network environment 100, UE 110 and the wireless network 120 may implement various schemes pertaining to handling regulatory prioritized services in a non-allowed area in mobile communications in accordance with the present disclosure, as described herein.
[0021] It is noteworthy that, while the various proposed schemes may be individually or separately described below, in actual implementations some or all of the proposed schemes may be utilized or otherwise implemented jointly. Of course, each of the proposed schemes may be utilized or otherwise implemented individually or separately. Moreover, as used herein, a lower layer may refer to a layer in the 5GMM protocol stack that is lower than the radio resource control (RRC) layer, such as a packet data convergence protocol (PDCP) layer, a radio control link (RLC) layer, a medium access control (MAC) layer, a physical (PHY) layer, or so forth.
[0022] Under a proposed scheme in accordance with the present disclosure, in case the UE 110 set a service type IE in a SERVICE REQUEST message transmitted by UE 110 to a network (e.g., wireless network 120) to “high priority access” and / or (b) UE 110 receives a reject message from the network with a 5GMM cause #28 as a result of sending such SERVICE REQUEST message, then UE 110 may perform one or more operations. The one or more operations may include at least one of the following: (1) not performing (e.g., refraining from performing) a registration procedure or service request procedure for a high priority access until UE 110 enters an allowed area or leaves a non-allowed area; and (b) refraining from responding to paging or notification (s) except for one or more emergency services while in a non-allowed area or not in an allowed area. Moreover, the network may indicate to UE 110, in an existing or new IE, location information (e.g., tracking area (TA) , public land mobile network (PLMN) , and so on) about where the high priority access is not allowed due to service area restriction (s) .
[0023] As a first implementation example, wireless network 120 may optionally convey an operator policy for service area restriction exemptions for UEs configured for high priority access in selected PLMN or standalone non-public network (SNPN) using the HPASE bit of the Feature authorization indication IE in the REGISTRATION ACCEPT message or the HPASE bit in the Feature authorization indication IE in the CONFIGURATION UPDATE COMMAND message, if UE 110 supports high priority access operations (HPAOP) .
[0024] As a second implementation example, if the service type IE in the SERVICE REQUEST message was set to "high priority access" and the network indicates "High priority access UEs are not exempt from service area restrictions" , UE 110 may not perform the procedure for mobility and periodic registration update or the service request procedure until UE 110 enters an allowed area or leaves a non-allowed area.
[0025] As a third implementation example, if the service type IE in the SERVICE REQUEST message was set to "high priority access" and the network does not indicate "High priority access UEs are not exempt from service area restrictions" , UE 110 may perform the procedure for mobility and periodic registration update or the service request procedure.

[0029] In one aspect, each of processor 212 and processor 222 may be implemented in the form of one or more single-core processors, one or more multi-core processors, or one or more CISC or RISC processors. That is, even though a singular term “a processor” is used herein to refer to processor 212 and processor 222, each of processor 212 and processor 222 may include multiple processors in some implementations and a single processor in other implementations in accordance with the present disclosure. In another aspect, each of processor 212 and processor 222 may be implemented in the form of hardware (and, optionally, firmware) with electronic components including, for example and without limitation, one or more transistors, one or more diodes, one or more capacitors, one or more resistors, one or more inductors, one or more memristors and / or one or more varactors that are configured and arranged to achieve specific purposes in accordance with the present disclosure.

In some implementations, transceiver 216 may be equipped with a plurality of antenna ports (not shown) such as, for example, four antenna ports. That is, transceiver 216 may be equipped with multiple transmit antennas and multiple receive antennas for multiple-input multiple-output (MIMO) wireless communications. In some implementations, apparatus 220 may also include a transceiver 226 coupled to processor 222. Transceiver 226 may include a transceiver capable of wirelessly transmitting and receiving data.

In some implementations, apparatus 220 may further include a memory 224 coupled to processor 222 and capable of being accessed by processor 222 and storing data therein. Each of memory 214 and memory 224 may include a type of random-access memory (RAM) such as dynamic RAM (DRAM) , static RAM (SRAM) , thyristor RAM (T-RAM) and / or zero-capacitor RAM (Z-RAM) . Alternatively, or additionally, each of memory 214 and memory 224 may include a type of read-only memory (ROM) such as mask ROM, programmable ROM (PROM) , erasable programmable ROM (EPROM) and / or electrically erasable programmable ROM (EEPROM) . Alternatively, or additionally, each of memory 214 and memory 224 may include a type of non-volatile random-access memory (NVRAM) such as flash memory, solid-state memory, ferroelectric RAM (FeRAM) , magnetoresistive RAM (MRAM) and / or phase-change memory.
[0032] Each of apparatus 210 and apparatus 220 may be a communication entity capable of communicating with each other using various proposed schemes in accordance with the present disclosure. For illustrative purposes and without limitation, a description of capabilities of apparatus 210, as a UE (e.g., UE 110) , and apparatus 220, as a network node (e.g., network node 125) of a network (e.g., wireless network 120 as a 5G / NR mobile network) , is provided below in the context of example processes 300, 400 and 500. Illustrative Processes
[0033] Each of FIG. 3, FIG. 4 and FIG. 5 illustrates an example process 300, example process 400 or example process 500, respectively, in accordance with an implementation of the present disclosure. Each of process 300, process 400 and process 500 may represent an aspect of implementing various proposed designs, concepts, schemes, systems and methods described above. More specifically, each of process 300, process 400 and process 500 may represent an aspect of the proposed concepts and schemes pertaining to handling regulatory prioritized services in a non-allowed area in mobile communications in accordance with the present disclosure. Each of process 300, process 400 and process 500 may include one or more operations, actions, or functions as illustrated by one or more of blocks 310, 320 and 330 for process 300, blocks 410 and 420 for process 400, and blocks 510 and 520 for process 500. Although illustrated as discrete blocks, various blocks of each of process 300, process 400 and process 500 may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Moreover, the blocks / sub-blocks of each of process 300, process 400 and process 500 may be executed in the order shown in FIG. 3, FIG. 4 and FIG. 5, respectively, or in a different order. Furthermore, one or more of the blocks / sub-blocks of each of process 300, process 400 and process 500 may be executed repeatedly or iteratively. Each of process 300, process 400 and process 500 may be implemented by or in apparatus 210 and apparatus 220 as well as any variations thereof. Solely for illustrative purposes and without limiting the scope, each of process 300, process 400 and process 500 is described below in the context of apparatus 210 as a UE (e.g., UE 110) and apparatus 220 as a communication entity such as a network node or base station (e.g., network node 125) of a network (e.g., wireless network 120) .

[0040] Process 400 may begin at block 410.
[0041] At 410, process 400 may involve processor 222 of apparatus 220, as network node 125 of wireless network 120, receiving, via transceiver 226, a service request message from a UE (e.g., apparatus 210) with a service type IE set to “high priority access” .

Additional Notes
[0048] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0049] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0050] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
[0051] From the foregoing, it will be appreciated that various implementations of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure.
