[0043] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0044] Indirect network sharing is a disaster recovery mechanism designed to address network disasters affecting carriers. When a carrier network enters a disaster state, the carriers activate an indirect network sharing architecture for disaster recovery. This means that another carrier network with the same network coverage area as the carrier network in the disaster state is responsible for connecting user equipment to the carrier network in the disaster state, enabling the user equipment to regain network service.
[0045] Figure 1 A schematic diagram illustrating a user equipment accessing its home network via an indirect network sharing mechanism according to some embodiments of the present disclosure is shown. Figure 1 As shown, the user equipment (UE) of operator A accesses the core network of operator X (which can be referred to as the construction operator) through the base station of operator X, and then accesses the core network of operator A (which can be referred to as the participating operator) through the core network of operator X. That is, the base station of operator X acts as a shared base station; it is connected only to the core network of operator X and not to the core network of core network A, thus simplifying the interface between the shared base station and the core network. The shared base station interacts with the core network of the participating operator through the core network of the construction operator.
[0046] Figure 2 A schematic diagram illustrating user equipment accessing its home network according to some embodiments of this disclosure is shown. Figure 2 As shown, Figure 2 It includes two scenarios: 2A and 2B.
[0047] Scenario 2A illustrates that when the base station of the UE's home network operator 1 is in normal condition, the UE accesses the core network of operator 1 through the base station of operator 1, and the user traffic is routed through the base station of operator 1 and the core network of operator 1.
[0048] Scenario 2B illustrates a scenario where, in the event of a disaster, the base station of Operator 1, the UE's home network, becomes a shared base station. The UE accesses Operator 1's core network via indirect network sharing. Indirect network sharing is characterized by the absence of an 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 - Operator 1's core network.
[0049] When a user equipment's home network enters a disaster state, the user equipment accesses the network through indirect network sharing. This means the user equipment can access the network normally without being aware of the disaster and initiate registration and session establishment processes. However, the network side needs to mark such user equipment for policy control and billing purposes. Based on this, this disclosure provides a communication method.
[0050] Figure 3 A flowchart illustrating a communication method according to some embodiments of the present disclosure is shown. Figure 3 As shown, the method of this embodiment is executed by AMF and includes step S302.
[0051] In step S302, when the first network is in a disaster situation, in response to the second network receiving the user equipment's request, the user equipment is identified to indicate the user equipment's access method, wherein the first network is the user equipment's home network and the second network is the AMF's home network.
[0052] A disaster situation in the first network includes a base station failure in the first network, causing user equipment to access the core network of the first network through a second network. This corresponds to the above. Figure 1 or Figure 2 The scenario described above. Access methods include indirect network sharing access during disaster situations, or access via indirect network sharing. This disclosure addresses the scenario where the user equipment's home network fails, and the user equipment accesses its home network through a shared base station. The AMF identifies the user equipment accessing in this scenario. This disclosure does not limit the specific naming convention used to describe the user equipment corresponding to the access method in this scenario.
[0053] By enabling the access and mobility management functions of the second network to identify the user equipment when the user equipment's home network (the first network) is in a disaster situation and the user equipment accesses the second network, the network can then perform corresponding policy control and billing functions based on the user equipment's access method, thereby improving the network's processing efficiency for user equipment.
[0054] In some embodiments, the request includes a registration request. Registration types include any one of initial registration, mobility registration, and periodic registration.
[0055] In some embodiments, the communication method further includes: in response to the second network receiving a registration request from a user equipment, determining the access method of the user equipment. That is, after receiving the registration request from the user equipment, the AMF determines whether the user equipment is accessed through indirect network sharing, or whether it is accessed through indirect network sharing in a disaster situation.
[0056] In some embodiments, determining the access method of a user equipment includes: determining the access method of the user equipment based on a registration request and the location information of the user equipment.
[0057] Based on the information carried in the registration request and the location information of the user equipment, AMF determines whether the user equipment is accessed through indirect network sharing or through indirect network sharing in a disaster situation.
[0058] In some embodiments, the registration request includes the identifier of the user equipment. Determining the access method of the user equipment based on the registration request and the location information of the user equipment includes: determining the identifier of a first network based on the identifier of the user equipment; and determining the access method of the user equipment based on the identifier of the first network and the location information of the user equipment. The identifier of the user equipment is, for example, a 5G Globally Unique Temporary Identifier (5G-GUTI). The AMF identifies the home network of the user equipment based on the 5G-GUTI, and then determines that the location of the user equipment is in a disaster area based on the location information of the user equipment, thereby confirming that the user equipment accesses the network through indirect network sharing, or accesses the network through indirect network sharing under disaster conditions.
[0059] After determining that the user equipment is accessed via indirect network sharing, or via indirect network sharing in a disaster situation, the AMF identifies the user equipment during the user equipment registration process.
[0060] In some embodiments, identifying a user equipment includes: in response to a second network receiving a registration request from the user equipment, providing first indication information to a UDM in the first network, wherein the first indication information is used to indicate the access method of the user equipment. The AMF provides the first indication information to the UDM, and the UDM can store the first indication information to mark that the user equipment is registered through disaster roaming, so as to inform other network functions.
[0061] In some embodiments, providing first indication information to the Unified Data Management Function (UDM) in the home network of a user equipment includes: sending an authentication request to the User Equipment Authentication and Management Service (AUSF) in the first network, wherein the authentication request includes the first indication information, and the AUSF provides the first indication information to the UDM. That is, the AMF sends an authentication request to the AUSF, and the authentication request includes the first indication information. After receiving the authentication request, the AUSF interacts with the UDM to obtain authentication information related to the user equipment, and therefore the AUSF can provide the first indication information to the UDM.
[0062] The AMF provides the first indication information to the UDM so that the UDM can mark the access method of the user equipment, and then use the first indication information in the network services related to the user equipment through the UDM. Furthermore, the AMF provides the first indication information to the UDM using the original registration process, which has low signaling overhead and is easy to implement.
[0063] In some embodiments, identifying the user equipment further includes: in response to the completion of authentication of the user equipment, sending registration information to the UDM to register the user equipment in the UDM, wherein the registration information includes first instruction information.
[0064] After authenticating the user equipment, the AMF registers with the UDM to establish a binding relationship with the user equipment. During registration, the registration information includes first indication information, indicating that the AMF is binding with the user equipment in the event of a first network disaster.
[0065] In some embodiments, identifying a user equipment further includes: obtaining subscription data of the user equipment from a UDM, wherein the subscription data is associated with the access method of the user equipment.
[0066] After registering in the UDM, the AMF obtains the user equipment's subscription data for subsequent use in user equipment session establishment, mobility management, etc. The subscription data is associated with the user equipment's access method, that is, the subscription data corresponding to the user equipment when accessing the network through indirect sharing.
[0067] In some embodiments, the request includes a session establishment request. That is, the user equipment is identified not only during the user equipment registration process but also during the user equipment session establishment process, in order to identify the user equipment's session data.
[0068] In some embodiments, identifying a user equipment includes: in response to a second network receiving a session establishment request from the user equipment, providing second indication information to a first SMF in the first network and a second SMF in the second network, wherein the second indication information is used to indicate the access method of the user equipment.
[0069] The second indication information is also used to indicate the access method of the user equipment. It is understood that the second indication information may or may not be the same as the first indication information. For example, the first and second indication information may be the same identifier, or they may indicate the access method of the user equipment in different ways.
[0070] The AMF provides second instruction information to the SMF of the first network and the SMF of the second network, so that the SMF of the first network and the SMF of the second network can perform session management, quality of service management, etc. based on the access method of the user equipment.
[0071] In some embodiments, the first SMF and the second SMF store the second indication information in at least one of the protocol data unit (PDU) session context and the billing data.
[0072] In some embodiments, providing second indication information to a first session management function (SMF) in a first network and a second SMF in a second network includes: providing second indication information to the second SMF, wherein the second SMF provides the second indication information to the first SMF.
[0073] The above is a description of the communication method of this disclosure based on the network side. The following is a description of the communication method of this disclosure based on the user equipment side.
[0074] Figure 4 A flowchart illustrating a communication method according to other embodiments of this disclosure is shown. For example... Figure 4 As shown, the communication method of this embodiment is executed by the user equipment and includes step S402.
[0075] In step S402, when the first network is in a disaster state, a request is initiated through the second network to identify the user equipment (UE) via the AMF (Access Provider Function) to indicate the UE's access method. The first network is the UE's home network, and the second network is the AMF's home network. A disaster state in the first network includes a base station failure, and the UE accessing the first network's core network via the second network. The access method includes shared access via an indirect network under disaster conditions, or shared access via an indirect network.
[0076] In some embodiments, the request includes a registration request.
[0077] In some embodiments, the communication method further includes: receiving a registration response sent by the AMF, wherein the registration response indicates that the user equipment registration is complete.
[0078] In some embodiments, the request includes a session establishment request.
[0079] In other words, when a user device is accessing the network normally, such as initiating registration and session establishment requests, the user device is unaware of a disaster on the network side.
[0080] Figure 5 A flowchart illustrating a communication method according to other embodiments of this disclosure is shown. For example... Figure 5 As shown, the method of this embodiment includes steps S502 to S516.
[0081] In step S502, within the disaster area, the shared base station broadcasts the Public Land Mobile Network Identifier (PLMN ID) representing the home network of the user equipment (i.e., the participating operator's network, which can be denoted as HPLMN). The network to which the shared base station belongs is the contractor's operator network, which can be denoted as VPLMN. The user equipment initiates a registration request to the shared base station; this registration request is a non-disaster registration request.
[0082] In step S504, the VPLMN's AMF (which can be referred to as V-AMF) determines that the current location belongs to a disaster area based on the information carried in the UE's registration request and the user location information provided by the shared base station, and confirms the provision of indirect network sharing services to the user equipment.
[0083] In step S506, V-AMF initiates an authentication request to HPLMN's AUSF (which can be referred to as H-AUSF). The authentication request includes first indication information, which is used to indicate the access method of the user equipment, that is, to indicate whether the user equipment is accessed through indirect network sharing in a disaster situation or through indirect network sharing.
[0084] In step S508, H-AUSF provides the first indication information to the UDM of HPLMN (which can be referred to as H-UDM).
[0085] In step S510, the authentication process for the user equipment is completed based on the interaction between AMF, AUSF, and UDM, i.e., authentication is accepted.
[0086] In step S512, V-AMF provides the first indication information to H-UDM for registration.
[0087] In step S514, V-AMF obtains the user equipment associated with the access method of the user equipment from H-UDM.
[0088] In step S516, V-AMF sends a registration response to the user equipment, and the user equipment accepts normal registration (i.e., non-disaster registration). At this time, the user equipment accesses the network through indirect network sharing.
[0089] The above embodiments describe the process of identifying a user device during the user device registration process, but do not show all the steps of the user registration process. It is understood that the user registration process also includes other steps not shown in the figures.
[0090] When a user equipment accesses the network via indirect network sharing, the AMF identifies the user equipment during the registration process, enabling the network side to identify the user equipment's access method (i.e., marking the user equipment as disaster-related). This allows for the execution of various network services based on the user equipment's access method, without the user equipment being aware of the disaster status or incurring any new signaling interaction burden.
[0091] Figure 6 A flowchart illustrating a communication method according to some embodiments of the present disclosure is shown. Figure 6 As shown, the communication method of this embodiment includes steps S602 to S610.
[0092] In step S602, the user equipment initiates a session establishment request to V-AMF.
[0093] In step S604, the V-AMF provides second indication information to the SMF (which can be referred to as V-SMF) of the VPLMN. The second indication information is used to indicate the access method of the user equipment.
[0094] In step S606, V-SMF stores the second indication information in at least one of the PDU session context and billing data.
[0095] In step S608, the V-SMF provides the second indication information to the SMF of the HPLMN (which can be referred to as H-SMF).
[0096] In step S610, H-SMF stores the second indication information in at least one of the PDU session context and billing data.
[0097] The above embodiments describe the process of identifying the user equipment during the user equipment session establishment process, but do not show all the steps of the user session establishment process. It is understood that the user session establishment process also includes other steps not shown in the figures.
[0098] When a user equipment accesses the network via indirect network sharing, the AMF identifies the user equipment during the session establishment process. This enables subsequent policy control and billing of the user equipment based on its access method, thereby improving the network's processing efficiency for the user equipment.
