[0002] With the continuous development of communication technology, the network can provide more rapid and stable services for user equipment. However, in some cases, the home network accessed by the user equipment (User Equipment, UE) will fail into a disaster state (Disaster Condition, DC), and the home network cannot continue to provide services for the user equipment. In the disaster state, how to provide effective services for the user equipment is a problem that has been studied. SUMMARY

[0003] In view of the problem that the home network cannot provide services for the user equipment in the disaster state, the present disclosure provides an access method.

[0004] According to some embodiments of the present disclosure, an access method is provided, which is executed by a user equipment and includes: receiving a waiting range sent by a participant operator network and saving; in a case where the participant operator network is in a disaster state, initiating a registration request to a builder operator network according to the waiting range.

[0005] In some embodiments, receiving the waiting range sent by the participant operator network includes: receiving the waiting range sent by the participant operator network through a registration process and / or a configuration update process.

[0006] In some embodiments, the access method further includes: receiving a broadcast message of a shared base station, wherein the broadcast message includes a public land mobile network (PLMN) ID representing the participant operator network, and the shared base station is a base station of the builder operator network.

[0007] In some embodiments, the PLMN ID is a home public land mobile network (HPLMN) ID or an equivalent home public land mobile network (EHPLMN) ID.

[0008] In some embodiments, the broadcast message further includes: indication information for indicating that the participant operator network is in the disaster state.

[0009] In some embodiments, in the case where the participant operator network is in the disaster state, initiating the registration request to the builder operator network according to the waiting range includes: determining that the participant operator network is in the disaster state according to the indication information; and initiating the registration request to the builder operator network according to the waiting range.

[0010] In some embodiments, initiating the registration request to the builder operator network according to the waiting range comprises: generating a random number within the waiting range, and starting a timer based on the random number; in response to the timer stopping, initiating the registration request to the builder operator network.

[0011] In some embodiments, the access method further comprises: in the case that the waiting range is not saved, in response to determining that the participant operator network is in the disaster state, initiating the registration request to the builder operator network.

[0012] In some embodiments, the higher the priority of the user equipment, the smaller the waiting range.

[0013] In some embodiments, the PLMN ID is a PLMN ID used by the participant operator network in the disaster state.

[0014] In some embodiments, the builder operator provides services for the user equipment of the participant operator in an indirect network sharing manner.

[0015] According to another embodiment of the present disclosure, a user equipment is provided, comprising: a receiving module configured to receive and save a waiting range sent by a participant operator network; and a sending module configured to initiate a registration request to a builder operator network according to the waiting range in the case that the participant operator network is in a disaster state.

[0016] According to still another embodiment of the present disclosure, an electronic device is provided, comprising: a processor; and a memory coupled to the processor for storing instructions, which, when executed by the processor, cause the processor to perform the access method of any embodiment of the present disclosure.

[0017] According to yet another embodiment of the present disclosure, a computer readable storage medium is provided, having stored thereon a computer program, wherein the program, when executed by a processor, implements the access method of any embodiment of the present disclosure.

[0018] According to still another embodiment of the present disclosure, a communication system is provided, comprising: the user equipment of any embodiment of the present disclosure; a participant operator network configured to send a waiting range to the user equipment; and a builder operator network configured to receive a registration request sent by the user equipment according to the waiting range in the case that the participant operator network is in a disaster state.

[0022] In the access method of the embodiments of the present disclosure, the user equipment receives and saves the waiting range sent by the participant operator network. If the participant operator network is in a disaster state, the user equipment initiates a registration request to the builder operator network according to the waiting range, so that the user equipment can access through the builder operator network and continue to use the communication service. In addition, by setting the waiting range, the user equipment can access the builder operator network after waiting for a certain time, reducing the probability that a large number of user equipments access the builder operator network to cause a signaling storm when the participant operator network enters a disaster state, improving the success rate of the user equipment accessing the builder operator network, and reducing the consumption of signaling.

[0045] The technical solutions of the various embodiments disclosed herein can be applied to various communication systems according to the access standard, such as: 5th generation (5G) or New Radio (NR) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, 6th generation (6G) mobile communication systems, etc. The technical solutions provided in this application can also be applied to Device-to-Device (D2D) communication, Vehicle-to-Everything (V2X) communication, Machine-to-Machine (M2M) communication, Machine-Type Communication (MTC), and Internet of Things (IoT) communication systems or other communication systems.

[0046] For example, the 5G system (5GS) architecture can include three parts: User Equipment (UE), Data Network (DN), and Carrier Network. The Carrier Network can include an access network and a core network.

[0047] User equipment (UE), also known as terminal equipment or terminal, is a device with wireless transceiver capabilities that can communicate with one or more core networks (CNs) via access network devices in a radio access network (RAN). It can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; on water, such as on ships; and in the air, such as on airplanes, balloons, or satellites. User equipment can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, self-driving, remote medical, smart grid, transportation safety, smart city, and smart home applications, among others.

[0048] A network (NW) can include an access network and a core network. A radio access network ((R)AN) provides network access functionality to authorized user equipment (UEs) in a specific area and can use transmission tunnels of different qualities depending on the UE's level and service requirements. For example, the (R)AN can manage radio resources, provide access services to UEs, and thus complete the forwarding of control and / or data information between UEs and the core network (CN).

[0049] (R)AN devices can provide access to communication networks for authorized users in a specific area. Specifically, they can include wireless network devices in 3GPP networks or access points in non-3GPP networks.

[0050] Access network equipment may include: next-generation node base stations (gNBs) in 5G systems, evolved node Bs (eNBs) in Long Term Evolution (LTE), or network equipment in future networks.

[0051] The core network includes multiple core network elements (or network function elements), such as: Access and Mobility Management Function (AMF) elements, Session Management Function (SMF) elements, User Plane Function (UPF) elements, Unified Data Management (UDM) elements, Application Function (AF) elements, Policy Control Function (PCF) elements, Authentication Server Function (AUSF) elements, Edge Application Server Discovery Function (EASDF) elements, and Network Exposure Function (NEF) elements, etc.

[0052] In the event of a disaster, when the home network is unable to provide services to user equipment, this disclosure proposes an access method, which is described below in conjunction with... Figure 1 Some embodiments of the access method disclosed herein are described.

[0053] Figure 1 Flowcharts are shown for some embodiments of the access method disclosed herein. For example... Figure 1 As shown, the method of this embodiment includes steps S102 to S104.

[0054] This disclosure provides an indirect network sharing architecture. In this architecture, the hosting operator provides a shared RAN, which is connected to the hosting operator's core network but not to the participating operator's core network. This simplifies the interface between the shared base station and the core network. The shared RAN interacts with the participating operator's core network through the hosting operator's core network.

[0055] The contractor operator is the operator that builds the shared access network, and there can be one or more participating operators, who are operators participating in the network sharing of the shared access network.

[0056] In step S102, the user equipment receives and saves the waiting range sent by the participating operator network, and correspondingly, the participating operator network sends the waiting range to the user equipment.

[0057] Under normal circumstances, a user equipment (UE) connects to the participating operator's network, i.e., its home network. When the participating operator's network is operating normally, it can send a wait range to the UE. The wait range can be represented by a numerical range, a maximum and minimum value, or simply the maximum value, and is not limited to the examples given. There can be one or more wait ranges. The wait range indicates the time interval between the UE becoming aware that the participating operator's network has entered a disaster state and the UE initiating a registration request.

[0058] In some embodiments, the user equipment receives a waiting range sent by the participating operator network through a registration process and / or a configuration update process, and correspondingly, the participating operator network sends the waiting range to the user equipment through the registration process and / or the configuration update process.

[0059] For example, in the registration process, the user equipment receives a first message sent by the base station of the participating operator, which may carry a waiting range. The first message may be a registration acceptance message, etc., and is not limited to the examples given. For example, in the configuration update process, the user equipment receives a second message sent by the base station of the participating operator, which may carry a waiting range. The second message may be a UE configuration update command, and is not limited to the examples given.

[0060] In some embodiments, the higher the priority of the user device, the smaller the waiting range.

[0061] Participating operator networks can configure waiting ranges for user devices based on their priority. Different priority user devices have different waiting ranges. The higher the priority of a user device, the smaller its waiting range. This means that high-priority user devices can initiate registration requests in a shorter time after the participating operator network enters a disaster state, thus restoring service sooner. Furthermore, configuring waiting ranges for user devices based on their priority allows multiple user devices from the participating operator to initiate registration requests in different time periods, thereby reducing the probability of signaling storms, conserving signaling resources, and improving the success rate of access.

[0062] For example, the priority of a user equipment (UE) is determined based on at least one of its service type and QoS (Quality of Service) level. For instance, the higher the latency requirement corresponding to the service type (the lower the required latency) and the higher the QoS level, the higher the priority of the UE.

[0063] In some embodiments, user equipment is divided into multiple groups based on the number of user equipment accessing the network from the participating operator's network. Each group is configured with a corresponding waiting range, and different groups have different waiting ranges.

[0064] By configuring different waiting ranges for user devices in different groups, multiple user devices of participating operators can initiate registration requests in different time periods, thereby reducing the probability of signaling storms, saving signaling resources, and improving the success rate of access.

[0065] In some embodiments, the user equipment stores the wait range in the non-volatile memory of the mobile device (ME).

[0066] In step S104, when the participating operator's network is in a disaster state, the user equipment initiates a registration request to the contractor operator's network according to the waiting range, and the contractor operator's network receives the registration request initiated by the user equipment.

[0067] In some embodiments, the contractor operator provides services to the user equipment of the participating operators through indirect network sharing.

[0068] User equipment (UE) can initiate a registration request to the contractor operator's shared access network or shared base station to access the contractor operator's network. The contractor operator can provide access services to the participating operators' UEs through indirect network sharing. After accessing the contractor operator's network, the UEs can interact with the participating operators' core networks through this indirect network sharing mechanism; that is, the UEs access the shared access network and interact with the participating operators' core networks through the contractor operator's core network. The UEs are located within the coverage area of ​​the contractor operator's network.

[0069] like Figure 2 As shown, Operator 1's network is normal, and the UE accesses Operator 1's network. Operator 1 is both a participating operator and the UE's home operator, while Operator 2 is the construction operator. The coverage areas of Operator 1's network and Operator 2's network can be the same, or the coverage area of ​​Operator 2's network can include the coverage area of ​​Operator 1's network. For example... Figure 3 As shown, Operator 1's base station malfunctions and enters a disaster state. Operator 2's base station becomes a shared base station, and UEs access Operator 1's core network through indirect network sharing. Indirect network sharing is reflected in the fact that there is no interface between Operator 2's base station and Operator 1's core network; user traffic is routed through Operator 2's base station, Operator 2's core network, and Operator 1's core network.

[0070] In some embodiments, the user equipment generates a random number within a waiting range and starts a timer based on the random number. In response to the timer stopping, it initiates a registration request to the contractor operator network.

[0071] User equipment (UE) does not initiate a registration request during the timer's runtime. When the timer expires, if the UE is still camped on the selected network, it initiates an initial registration procedure. Since the actual time from when the participating operator's network enters a disaster state to when the UE initiates a registration request is random, this reduces the probability of signaling storms, conserves signaling resources, and improves access success rates.

[0072] In the access method described in the above embodiments, the user equipment receives and saves the waiting range sent by the participating operator network. If the participating operator network is in a disaster state, the user equipment initiates a registration request to the contractor operator network according to the waiting range, thereby accessing the network and continuing to use communication services. Furthermore, by setting a waiting range, the user equipment can wait a certain period before accessing the contractor operator network, reducing the probability of a signaling storm caused by a large number of user equipments accessing the contractor operator network if the participating operator network enters a disaster state, thus increasing the success rate of user equipment accessing the contractor operator network and reducing signaling consumption.

[0073] When a user device (User Equipment) initiates a registration request to the contractor's (User Network Operator) network based on the waiting range during a disaster, how can we ensure that the User Equipment can accurately access the contractor's network? The following discussion will address this issue in conjunction with... Figure 4 Some other embodiments of the access method described herein are described.

[0074] Figure 4 Flowcharts are shown for some other embodiments of the access method disclosed herein. For example... Figure 4 As shown, the method of this embodiment includes steps S402 to S412.

[0075] In step S402, the user equipment receives and saves the waiting range sent by the participating operator network.

[0076] The waiting range can be sent from the core network of the participating operator to the base station of the participating operator, and the base station of the participating operator will then forward the waiting range to the user equipment. The participating operator's network can provide the waiting range through a registration process or a configuration update process.

[0077] In step S404, the base station of the participating operator fails, entering a disaster state.

[0078] In step S406, the shared base station of the contractor operator sends a broadcast message, and the user equipment receives the broadcast message sent by the shared base station.

[0079] The broadcast message includes the PLMN (Public Land Mobile Network) ID representing the participating operator's network. The contractor operator's network is configured to provide disaster recovery services via indirect network sharing, activating the indirect network sharing architecture. Since the participating operator is the home operator to which the user equipment (UE) is contracted, the UE can only access the network corresponding to the PLMN ID representing the participating operator's network. Therefore, broadcasting the PLMN ID representing the participating operator's network by the shared base station allows the UE to access the contractor operator's network more accurately.

[0080] Broadcast messages can be newly added SIBs (System Information Blocks) or SIB5.

[0081] In some embodiments, the PLMN ID is either HPLMN (Home Public Land Mobile Network) ID or EHPLMN (Equivalent Home PLMN) ID.

[0082] Once a disaster state begins, shared base stations in the affected area can broadcast a PLMN ID representing the HPLMN, allowing HPLMN users to access the system.

[0083] The PLMN ID broadcast by the shared base station can be the ID of any available PLMN that allows user equipment to access. In some embodiments, the PLMN ID is the PLMN ID used by the participating operator's network in a disaster situation.

[0084] The PLMN ID broadcast by the shared base station can be a PLMN ID specifically for disaster situations. User equipment can determine from this PLMN ID that the participating operator's network is in a disaster state and needs to access the shared base station.

[0085] In some embodiments, the broadcast message may further include: indication information for indicating that the participating operator's network is in a state of disaster.

[0086] The user equipment determines that the HPLMN is in a faulty state based on the instruction information broadcast by the shared base station, selects a PLMN ID representing the HPLMN from the available networks broadcast by the shared base station, and re-registers based on the PLMN ID.

[0087] In step S408, the user equipment determines that the participating operator network is in a disaster state based on the indication information, and selects a PLMN ID representing the participating operator network.

[0088] In step S410, the user equipment initiates a registration request to the contractor operator's network based on the waiting range.

[0089] The user equipment generates a random number within the waiting range and starts a timer using the generated random value. During the timer's execution, the user equipment does not initiate a registration request. When the timer expires, if the user equipment is still registered on the selected network (the network corresponding to the PLMN ID), the user equipment initiates the initial registration process.

[0090] User equipment can send a registration request to the shared base station, which then sends the registration request to the core network of the participating operators through the core network of the contractor operator.

[0091] In step S412, the user equipment receives a registration acceptance message sent by the shared base station.

[0092] The core network of the participating operator sends a registration acceptance message to the core network of the contractor operator, and then sends the registration acceptance message to the user equipment through the shared base station.

[0093] In some embodiments, the user equipment initiates a registration request to the contractor operator network in response to determining that the participating operator network is in a disaster state, without saving the waiting range.

[0094] The user equipment may not have received the waiting range or may not have saved the waiting range for other reasons. In this case, the user equipment can initiate a registration request based on the broadcast PLMN ID when it is determined that the participating operator's network is in a disaster state.

[0095] In the method described in the above embodiments, when a participating operator's network enters a disaster state, the shared base station of the contractor operator will broadcast an indication message indicating that the participating operator's network is in a disaster state. It may also broadcast the PLMN ID of the participating operator's network. Thus, user equipment can accurately access the shared base station based on the broadcast message and the waiting range, interacting with the participating operator's core network through indirect network sharing. This ensures communication services for user equipment. Furthermore, based on the waiting range setting, it reduces the probability of a large number of user equipments accessing the contractor operator's network and causing a signaling storm if the participating operator's network enters a disaster state, thereby increasing the success rate of user equipment accessing the contractor operator's network and reducing signaling consumption.

[0096] This disclosure also proposes a user equipment, which is described below in conjunction with... Figure 5 Describe it.

[0105] In some embodiments, the sending module 520 is configured to generate a random number within a waiting range and start a timer based on the random number; in response to the timer stopping, it initiates a registration request to the contractor operator network.

[0106] In some embodiments, the sending module 520 is further configured to initiate a registration request to the contractor operator network in response to determining that the participating operator network is in a disaster state, without saving the waiting range.

[0107] In some embodiments, the higher the priority of the user device, the smaller the waiting range.

[0108] In some embodiments, the PLMN ID is the PLMN ID used by the participating operator's network in a disaster state.

[0109] In some embodiments, the contractor operator provides services to the user equipment of the participating operators through indirect network sharing.
