Description

Technical Field

[0001] This disclosure relates to the field of 5G communication technology, and more specifically, to a user equipment access network method, a user equipment access network apparatus, a computer-readable storage medium, and an electronic device. Background Technology

[0002] In existing 5G disaster roaming services, only the restriction of the list of prohibited public terrestrial mobile networks is considered; therefore, when the public terrestrial mobile network used for disaster roaming services is not on the list of prohibited public terrestrial mobile networks, the user equipment cannot initiate an access request to that public terrestrial mobile network.

[0003] It should be noted that the information in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] The purpose of this disclosure is to provide a user equipment access network method, user equipment access network apparatus, computer-readable storage medium, and electronic device, thereby overcoming, at least to some extent, the inability to initiate access requests to public land mobile networks not present in the list of prohibited public land mobile networks due to limitations and defects in related technologies.

[0005] According to one aspect of this disclosure, a user equipment access network method is provided, configured in a user equipment, the user equipment access network method comprising:

[0006] Ignore the tracking area identifiers in the disabled list and select the public terrestrial mobile network for disaster roaming services.

[0007] In one exemplary embodiment of this disclosure, the disable list includes at least one of the following: a list of tracking areas where roaming is prohibited, a list of tracking areas where roaming is prohibited provided by the regional service, and a list of tracking areas where roaming is prohibited by 5GS.

[0008] In one exemplary embodiment of this disclosure, the public land mobile network currently in which the user equipment is located in a disaster state is a first public land mobile network, and the public land mobile network used for disaster roaming service is a second public land mobile network; wherein ignoring the tracking area identifier in the disabled list includes: when receiving disaster roaming information broadcast by a base station of the second public land mobile network, ignoring the tracking area identifier in the disabled list.

[0009] In one exemplary embodiment of this disclosure, the disaster roaming information includes at least one of the following: a disaster-related indication of a second public land mobile network; a public land mobile network list consisting of one or more public land mobile networks in a disaster state, wherein the second public land mobile network is capable of providing disaster roaming services to one or more public land mobile networks in the public land mobile network list that are in a disaster state.

[0010] In one exemplary embodiment of this disclosure, the list of public land mobile networks includes a first public land mobile network; the disaster-related indication is used to indicate that a second public land mobile network is capable of providing disaster roaming services to the first public land mobile network in a disaster state.

[0011] In one exemplary embodiment of this disclosure, the disaster roaming information is broadcast by the base station when the first public terrestrial mobile network is in a disaster state.

[0012] In one exemplary embodiment of this disclosure, the disable list is generated by: initiating a registration request to a second public terrestrial mobile network; receiving registration rejection information from the second public terrestrial mobile network in response to the registration request; obtaining the 5G mobile management message reason value included in the registration rejection information; and generating the disable list based on the 5G mobile management message reason value.

[0013] In one exemplary embodiment of this disclosure, the 5G mobile management message reason value includes at least one of the following: a first reason value corresponding to roaming prohibition in the tracking area, and a second reason value corresponding to no suitable cell in the tracking area.

[0014] In one exemplary embodiment of this disclosure, the access network method of the user equipment further includes: initiating a disaster roaming registration request to a second public terrestrial mobile network; and accessing the second public terrestrial mobile network in response to registration approval information fed back by the second public terrestrial mobile network based on the disaster roaming registration request.

[0015] According to one aspect of this disclosure, an access network apparatus for a user equipment is provided, configured in the user equipment, the access network apparatus of the user equipment comprising: a tracking area identifier ignoring module, configured to ignore tracking area identifiers in a disabled list and select a public terrestrial mobile network for disaster roaming services.

[0016] According to one aspect of this disclosure, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the user equipment access network method described in any of the preceding claims.

[0017] According to one aspect of this disclosure, an electronic device is provided, comprising: a processor; and a memory for storing executable instructions of the processor; wherein the processor is configured to perform the user equipment access network method described in any of the preceding claims by executing the executable instructions.

[0018] This disclosure provides a user equipment access network method. On one hand, it selects a public land mobile network (PTN) for disaster roaming services by ignoring the tracking area identifier in the disabled list. Since the PTN for disaster roaming services is selected by ignoring the tracking area identifier in the disabled list, rather than ignoring the restrictions of the prohibited PTN list, the user equipment can initiate an access request to the PTN for disaster roaming services regardless of whether it exists in the disabled list. This solves the problem in the prior art that it is impossible to initiate an access request to a PTN that does not exist in the prohibited PTN list. On the other hand, since the PTN for disaster roaming services is selected by ignoring the tracking area identifier in the disabled list, rather than ignoring the restrictions of the prohibited PTN list, the disaster recovery capability of the network is improved, and the user experience is enhanced.

[0029] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, apparatus, steps, etc., can be employed. In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0030] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0031] This exemplary embodiment first provides a user equipment access network method, which can run on a user equipment. The user equipment described herein may include, but is not limited to: VR / AR devices, terminals in V2X communication, user units (stations), mobile stations (stations), remote stations, remote terminals, mobile devices, user terminals, terminal devices, or wireless communication devices, etc. Of course, those skilled in the art can also run the method disclosed herein on other platforms as needed, and this exemplary embodiment does not impose any special limitations on this. Specifically, refer to... Figure 1 As shown, the user equipment access network method may include the following steps:

[0032] Step S110. Ignore the tracking area identifiers in the disabled list and select the public terrestrial mobile network for disaster roaming service.

[0033] In the aforementioned user equipment access network method, on the one hand, a public land mobile network (PTN) for disaster roaming services is selected by ignoring the tracking area identifier in the disabled list. Since the PTN for disaster roaming services is selected by ignoring the tracking area identifier in the disabled list, rather than ignoring the restrictions of the prohibited PTN list, the user equipment can initiate an access request to the PTN for disaster roaming services regardless of whether it exists in the disabled list. This solves the problem in the prior art that it is impossible to initiate an access request to a PTN that does not exist in the prohibited PTN list. On the other hand, since the PTN for disaster roaming services is selected by ignoring the tracking area identifier in the disabled list, rather than ignoring the restrictions of the prohibited PTN list, the network's disaster recovery capability is improved, and the user experience is enhanced.

[0034] The following will provide a detailed explanation and description of the user equipment access network method described in the exemplary embodiments of this disclosure, in conjunction with the accompanying drawings.

[0035] First, the terms used in the exemplary embodiments of this disclosure will be explained and described.

[0036] Disaster Roaming: Both PLMN-2 (Public Land Mobile Network-2) and PLMN-1 (Public Land Mobile Network-1) have 5G network coverage at the current location of the UE (User Equipment) (see specific scenario example diagrams for reference). Figure 2As shown; where 201 is the area covered by PLMN-1 and 202 is the area covered by PLMN-2); and, under normal circumstances, user equipment in PLMN-1 cannot access PLMN-2 because PLMN-2 is in the UE's forbidden PLMN list; under this premise, when PLMN-1 experiences a network failure and enters a disaster state and cannot provide network services, PLMN-2 can provide disaster roaming services to the UE at its current location; at the same time, the UE ignores the restrictions of the forbidden PLMN list, selects PLMN-2 from the forbidden PLMN list to initiate disaster roaming registration to obtain basic communication services, which is called disaster roaming.

[0037] Secondly, the technical implementation principles of the exemplary embodiments disclosed herein will be explained and described. Specifically, the current 3GPP (3rd Generation Partnership Project) supports 5G disaster roaming service; wherein, the 5G disaster roaming service described herein refers to the situation where, when the PLMN (Public Land Mobile Network-1) in the 5G communication network enters a disaster state and cannot provide services, the UE (User Equipment) originally in PLMN-1 breaks through the restrictions of the forbidden PLMN list and roams to PLMN-2 to obtain basic communication services. However, the 5G disaster roaming service described here only considers bypassing the forbidden PLMN list restriction. That is, PLMN-2 must be in the UE's forbidden PLMN list; otherwise, the UE will not attempt to initiate a disaster roaming request to PLMN-2. Under this premise, if PLMN-2 is not in the UE's forbidden PLMN list, but the current TAI (Tracking Area Identity) is the UE's forbidden TAI (forbidden tracking area identity), i.e., stored in the user equipment's list of "5G System forbidden tracking areas for roaming," then the UE cannot access PLMN-2 normally, nor can it access PLMN-2 for disaster roaming. The UE's forbidden PLMN list described here can be found by referring to... Figure 3 As shown here, the list of "5G System forbidden tracking areas for roaming" can be referenced. Figure 4 As shown. Based on this, the exemplary embodiments of this disclosure provide a user equipment access network method that can solve this problem.

[0038] The following will combine Figures 2-4 right Figure 1 The user equipment access network method shown will be further explained and illustrated. Specifically:

[0039] In step S110, the tracking area identifiers in the disabled list are ignored, and the public terrestrial mobile network for disaster roaming service is selected.

[0040] In this example embodiment, the tracking area identifiers in the disabled list are first ignored. Specifically, the disabled list described here includes a list of tracking areas prohibited from roaming, a list of tracking areas prohibited by regional service provision, a list of tracking areas prohibited from roaming by 5GS, etc. The list of tracking areas prohibited from roaming can also be referred to as a List of forbidden tracking areas for roaming; the list of tracking areas prohibited by regional service provision can also be referred to as a List of forbidden tracking areas for regional provision of service; the list of tracking areas prohibited from roaming by 5GS can also be referred to as a List of 5G System forbidden tracking areas for roaming. In practical applications, the list of tracking areas prohibited from roaming is used to record the tracking area identifiers that prohibit user equipment from tracking locations at the current location. Specific scenario example diagrams can be found in the provided diagram. Figure 5 As shown; the list of prohibited tracking areas provided by the area service records; the list formed by the identifiers of the areas where the user equipment is prohibited from tracking in the current location. For specific scenario examples, please refer to the diagram. Figure 6 As shown; it should be noted here that, in Figure 4 The list shown lists forbidden tracking areas for 5G systems. Figure 5 The list shown is of forbidden tracking areas for roaming and Figure 6The List of forbidden tracking areas for regional provision of service shown can include tracking areas that are partially the same, all the same, or all different. In actual application, the settings can be made according to the actual situation. This example does not impose any special restrictions on this.

[0041] In one possible example embodiment, the disabled list maintained by the user equipment may include any one, any two, or any three of the following: a list of tracking areas prohibited from roaming, a list of tracking areas prohibited from roaming provided by the regional service, and a list of tracking areas prohibited from roaming by 5GS. At the same time, in the process of ignoring tracking area identifiers in the disabled list, some or all tracking area identifiers in any one or any two or three of the disabled lists may be ignored, etc. This example does not impose any special restrictions on this.

[0042] In one example embodiment, the public terrestrial mobile network (PTN) in which the user equipment described above is currently located in a disaster state is the first PTN (i.e., PLMN-1); the PTN used for disaster roaming service is the second PTN (i.e., PLMN-2). Under this premise, ignoring the tracking area identifier in the disabled list can be achieved as follows: when receiving disaster roaming information broadcast by the base station of the second PTN, the tracking area identifier in the disabled list is ignored. That is, in actual application, when the base station (NG-RAN) enters a disaster state in the first PTN, it broadcasts disaster roaming information; when the user equipment at the current location receives the disaster roaming information, it ignores the tracking area identifier in the disabled list (the list of tracking areas prohibited from roaming and / or the list of tracking areas prohibited from roaming provided by the regional service and / or the list of tracking areas prohibited from roaming by 5GS).

[0043] In one exemplary embodiment, the disaster roaming information described above includes at least one of the following: a disaster-related indication of a second public land mobile network; a list of public land mobile networks consisting of one or more public land mobile networks in a disaster state, wherein the second public land mobile network is capable of providing disaster roaming services to one or more public land mobile networks in the list in a disaster state; wherein the list of public land mobile networks described herein includes a first public land mobile network; and the disaster-related indication described herein is used to indicate that the second public land mobile network is capable of providing disaster roaming services to the first public land mobile network in a disaster state. Specifically, the list of public land mobile networks (PTNs) described herein may include one or more PTNs in a state of disaster. The specific constraints are as follows: each of the included PTNs in a state of disaster requires a second PTN to provide corresponding disaster roaming services; that is, the coverage area of ​​each of the included PTNs in a state of disaster must be within the coverage area of ​​the second PTN; on this basis, the second PTN can only provide disaster roaming services when a PTN in the list of public land mobile networks is in a state of disaster.

[0044] In one example embodiment, the aforementioned ban list is generated by: initiating a registration request to a second public land mobile network; receiving registration rejection information from the second public land mobile network in response to the registration request; obtaining the 5G mobile management message reason value included in the registration rejection information; and generating the ban list based on the 5G mobile management message reason value. In other words, in practical applications, the user equipment first generates a registration request (the registration request described here can be a normal registration request) and sends the registration request to the second public land mobile network (PLMN-2) to request registration as an access network device of the second public land mobile network. When the second public land mobile network receives the registration request, it determines whether the user equipment meets the registration conditions based on the device identifier in the registration request. If it determines that the registration conditions are not met, it will send a registration rejection message. Here, it is assumed that PLMN-2 will definitely reject the registration request sent by the user equipment located within the coverage area of ​​the first public land mobile network. Under this premise, the second public land mobile network will send a registration rejection message to the user equipment located within the coverage area of ​​the first public land mobile network. Furthermore, when the user equipment receives the registration rejection message, it can generate a corresponding ban list based on the 5G Mobility Management (5GMM) message reason value included in the registration rejection message.

[0045] In one example embodiment, the 5G mobility management message reason value described above includes at least one of the following: a first reason value corresponding to roaming prohibition in the tracking area and a second reason value corresponding to the lack of a suitable cell in the tracking area. That is, the reason value carried in the 5G mobility management message may include #13 or #15; at the same time, the UE stores the current TAI (Tracking Area Identifier) ​​in the list of "5GS forbidden tracking areas for roaming", or it may be in the list of 5G System forbidden tracking areas for roaming, or it may be in the list of forbidden tracking areas for roaming, etc., and this example does not impose any special restrictions on this.

[0046] In one exemplary embodiment, after a user equipment (UE) selects a public terrestrial mobile network (PTN) for disaster roaming services (i.e., a second PTN), the UE's access method further includes: initiating a disaster roaming registration request to the second PTN; and accessing the second PTN in response to registration approval information fed back by the second PTN based on the disaster roaming registration request. Specifically, the disaster roaming registration request described herein may include device identification information, the device's current location information, and the first PTN currently accessed in a disaster state. It may also include other information, such as device type information or specific access methods (e.g., normal access or disaster roaming access), etc., which are not specifically limited in this example. Upon receiving the disaster roaming registration request, the second PTN can register the UE based on the information included in the request, thereby approving the UE's registration and granting access to the second PTN for normal network access. This avoids the problem of the UE being unable to access the network normally when the PTN is in a disaster state.

[0047] The following will further explain and illustrate the user equipment access network method described in the exemplary embodiments of this disclosure with reference to specific examples. Specifically, the specific implementation process of the user equipment access network method may include the following steps:

[0048] Step S001: The user equipment generates a registration request and sends the registration request to the second public land mobile network PLMN-2 for disaster roaming services in order to attempt to register with PLMN-2;

[0049] In step S002, after receiving the registration request, the second public land mobile network PLMN-2 sends a registration rejection message to the user equipment; the rejection message carries the 5G mobile management message reason value.

[0050] In step S003, the user equipment generates a disabled list based on the 5GMM cause value #13 or #15 in the registration rejection message; at the same time, the user equipment sends a registration request to the first public land mobile network to request 5G services provided by the first public land mobile network.

[0051] Step S004: The first public land mobile network enters a disaster state, and the base station broadcasts disaster roaming information; wherein, the disaster roaming information includes a disaster-related indication of PLMN-2, or a list of one or more PLMNs in a disaster state that can provide disaster roaming services; at the same time, the PLMN list includes PLMN-1;

[0052] Step S005: After the user equipment receives the disaster roaming information broadcast by the base station, the UE ignores the current TAI in the disabled list and selects the public land mobile network PLMN-2 for disaster roaming service.

[0053] Step S006: The user equipment disaster roaming accesses PLMN-2 to obtain 5G service.

[0054] Thus, the user equipment access network method described in the exemplary embodiments of this disclosure has been fully implemented. Based on the foregoing description, it can be understood that the user equipment access network method described in the exemplary embodiments of this disclosure can solve the problem that existing technologies only consider scenarios where the PLMN providing disaster roaming services is a disabled PLMN, but do not consider scenarios where the PLMN providing disaster roaming services is not a disabled PLMN but rather the current TAI is stored in the disabled TAI list, resulting in the inability to perform disaster roaming access. Based on the user equipment access network method provided in the exemplary embodiments of this disclosure, the gap in the scheme for enabling user equipment to initiate disaster roaming registration requests to non-disabled PLMNs is filled, thereby achieving the purpose of improving disaster roaming functionality and enhancing network disaster recovery capabilities.
