[0053] The access information transmission method, apparatus, and network device provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0054] like Figure 2 As shown in the figure, this application provides an access information transmission method. The execution subject of this method is a first network device; in other words, the method can be executed by software or hardware installed on the first network device. The method includes the following steps.

[0055] S210, The first network device obtains first information, which is used to indicate access selection information of the first network.

[0056] It should be noted that the first network device is a network device with application function (AF) in the first network. Specifically, it can be an application function entity in the first network. The first network is a network that provides local services to the terminal, and can also be called a hosting network. For example, it can be a stand-alone non-public network (SNPN) or a public network integrated non-public network (PNI-NPN).

[0057] The second network device is a network device with unified data management function in the second network. Specifically, it can be a unified data management entity (UDM) or a unified data repository (UDR) in the second network. The second network is the home network of the terminal, which can also be called the home network.

[0058] For simplicity, the following embodiments will use the example of the first network being the Hosting network, the first network device being AF1, the second network being the Home network, and the second network device being UDM2.

[0059] The terminal can sign up with a local service provider according to its actual needs, such as purchasing tickets or signing up online. The signing process can be completed using a mobile network or a network outside the 3GPP scope.

[0060] Through the aforementioned subscription process, the local service provider can obtain the terminal's identifier (UEID) and the list of subscribed local services.

[0061] After completing the agreement with the terminal, the local service provider will notify the first network to complete the agreement with the terminal, enabling the first network device to obtain the first information.

[0062] Optionally, the first information includes at least one of the following:

[0063] The identifier of the terminal;

[0064] Access selection information of the first network;

[0065] The terminal's local service list.

[0066] Optionally, the access selection information of the first network may include at least one of the following:

[0067] The network identifier of the first network is the network identifier of the Hosting network;

[0068] Access validity information, such as the valid location and valid time for access;

[0069] Identification information for local services;

[0070] The relevant information corresponding to the local service.

[0071] Optionally, the relevant information corresponding to the local service includes at least one of the following pieces of information about the local service:

[0072] Slice information;

[0073] Data Network Name (DNN).

[0074] S220, the first network device sends second information to the second network device, the second information being used to indicate the access selection information of the first network.

[0075] Optionally, the second information includes at least one of the following:

[0076] The identifier of the terminal;

[0077] Access selection information of the first network;

[0078] The terminal's local service list.

[0079] In one implementation, the second network device can directly obtain the access selection information of the first network from the second information. Optionally, the access selection information may include at least one of the following:

[0080] The network identifier of the first network;

[0081] Access validity information, such as the valid location and valid time for access;

[0082] Identification information for local services;

[0083] The relevant information corresponding to the local service.

[0084] In another implementation, the first network may further negotiate with the second network and store the list of supported local services on the second network. Each item in the local service list may include a reference ID, local service identification information, and related information corresponding to the local service, such as slice information, DNN, etc. The reference ID may be the local service identification information. The first network device instructs the second network device to retrieve the relevant information corresponding to the local service corresponding to the reference ID or local service identification information from the local service list via second information. In this case, the second information may include at least one of the following: terminal identifier, reference ID, local service identification information, and access validity condition information.

[0085] After obtaining the access selection information of the first network based on the second information, the second network device may optionally update the subscription information of the terminal based on the access selection information.

[0086] In one embodiment, after receiving the second information, the second network device may further send access selection information of the first network to the terminal, so that the terminal can access the first network and obtain local services provided by the first network according to the access selection information. The access selection information of the first network may include: the network identifier of the first network, access validity condition information, identifier information of the local service, and related information corresponding to the local service.

[0087] As can be seen from the technical solutions of the above embodiments, the embodiments of this application obtain first information, which is used to indicate access selection information of the first network; and then send second information to the second network device, which is used to indicate access selection information of the first network, so that the second network device sends access selection information of the first network to the terminal, thereby enabling the terminal to successfully obtain access selection information.

[0088] Based on the above embodiments, such as Figure 3 As shown, in one embodiment, the access selection information transmission method includes the following steps.

[0089] S310. The terminal UE signs up with the local service provider LSP's AF0. By signing up with the LSP, the UEID and the list of signed local services can be obtained.

[0090] S320.AF0 notifies the Hosting network that the terminal has completed the subscription through the Network Exposure Function (NEF) NEF1 of the Hosting network, so that AF1 can obtain the first information.

[0091] S330.AF1 sends a second message to UDM2 via NEF2 of the Home network to send access selection information for the Hosting network and UEID, etc. to the UDM2.

[0092] S340.UDM2 sends access selection information for the Hosting network to the UE.

[0093] Steps S320 and S330 can be implemented Figure 2 The method embodiments of steps S210 and S220 are repeated here to achieve the same technical effect, and the repeated parts will not be described again.

[0094] In one implementation, such as Figure 4 As shown, step S320 includes:

[0095] S322. After the UE and LSP successfully complete the subscription, AF0 sends a first message to the third network device via NEF1. The first message is used to instruct the local service provider to complete the subscription with the terminal. Specifically, the first message may be a local service subscription success message.

[0096] The first message carries at least one of the following:

[0097] The identifier of the terminal;

[0098] Access selection information of the first network;

[0099] The terminal's local service list.

[0100] The third network device is a network device with unified data management function in the Hosting network. Specifically, it can be a unified data management entity or a unified data storage repository. For simplicity, UDM1 will be used as an example for illustration in the following embodiments.

[0101] S323, AF1 receives the local service subscription information of the terminal from UDM1. The local service subscription information is sent by UDM1 after determining that the terminal has completed the subscription with the local service provider.

[0102] The local service subscription information includes at least one of the following:

[0103] The identifier of the terminal;

[0104] Access selection information of the Hosting network;

[0105] The terminal's local service list.

[0106] In one implementation, the access selection information of the hosting network can also be obtained from AF1. AF1 pre-stores relevant information related to the access selection information. The local service subscription information sent by UDM1 to AF1 includes the identifier of the terminal and / or the local service list of the terminal. AF1 obtains the access selection information of the hosting network from the stored relevant information based on the identifier of the terminal and / or the local service list of the terminal.

[0107] Optional, such as Figure 4 As shown, the method further includes the following steps before step S322:

[0108] S321, AF1 sends a subscription request to UDM1, the subscription request being used to subscribe to the local service subscription information signed by the terminal from UDM1.

[0109] In step S340, UDM1 can send access selection information to the terminal in various ways, such as through the UE Parameter Update (UPU) procedure or the Steering of Roaming (SoR) procedure. If the UPU procedure is used, the access selection information of the hosting network can be included in the UPU container and transmitted to the UE; if the SoR procedure is used, the access selection information of the hosting network can be included in the SoR container and transmitted to the UE.

[0110] If the terminal is not currently in the first network, then the UDM1 needs to transmit the access selection information to the terminal through a third network. The third network is the mobile network currently providing services to the terminal, also known as the Serving network, such as a non-public network (NPN) or a public land mobile network (PLMN).

[0111] In one implementation, such as Figure 5 As shown, step S340 may include the following steps.

[0112] After obtaining the second information, S341 and UDM2 can decide whether to trigger the UPU process or the SoR process.

[0113] S342 and UDM2 send a data management notification message to the Access and Mobility Management Function (AMF) 3 of the Serving network. This message can be a Subscription Data Management Notification (SDM Notification), represented as Nudm_SDM_Notification. The data management notification message includes access selection information for the Hosting network. If a UPU procedure is triggered, it is contained in the UPU container; if a SoR procedure is triggered, it is contained in the SoR container.

[0114] S343 and AMF3 send downlink messages to the terminal, the downlink messages including access selection information of the Hosting network. The downlink messages can be downlink non-access stratum transport messages (DLNASTRANSPORT).

[0115] As can be seen from the technical solutions of the above embodiments, the embodiments of this application send access selection information to the terminal by triggering the UPU process or the SoR process, so that the terminal can successfully obtain the access selection information.

[0116] Based on the above embodiments, there may be agreements between each pair of the Home network, Hosting network, and LSP, and all three can directly provide the UE with network selection information for accessing the Hosting network. However, if there is no agreement between the Home network and the Hosting network, the Serving network needs to be used for forwarding.

[0117] In one implementation, such as Figure 6 As shown, the access information transmission method includes the following steps.

[0118] S410, the terminal and the local service provider LSP sign an AF0 agreement.

[0119] S420 and AF0 notify the Hosting network via NEF1 that the terminal has completed the subscription, so that AF1 can obtain the first information.

[0120] S431-S432, In the absence of a protocol between the second network and the first network, AF1 sends second information to UDM2 through the third network, specifically including, for example... Figure 6As shown: AF1 sends the second information to UDM2 through a fourth network device. The fourth network device is a network device with application functions in the third network, specifically an application function entity AF3. AF1 sends the second information to AF3 through NEF3, and then AF3 sends the second information to UDM2 through NEF2.

[0121] S440 and UDM2 send access selection information to the UE.

[0122] Steps S410-S440 can achieve the following: Figure 3 The method embodiment of steps S310-S340 shown is used to achieve the same technical effect, and the repeated parts will not be described again here.

[0123] During the subscription process in step S410, the LSP also needs to obtain the network identifier (Serving Network ID) of the Serving network where the terminal is currently located, and inform the Hosting network of the terminal's current Serving network, so that the Hosting network can send the Hosting network's access selection information to the Serving network in step S431.

[0124] The LSP can obtain the ServingNetwork ID by either having the terminal directly send the ServingNetwork ID to AF0 in step S410, or by having the LSP obtain the Serving network to which the terminal is located based on the terminal's identifier.

[0125] In one implementation, the first information in step S420 may also include the ServingNetworkID; correspondingly, the second information in S431-S432 may also include the ServingNetwork ID.

[0126] As can be seen from the technical solutions of the above embodiments, in the absence of a protocol between the second network and the first network, the embodiments of this application send second information to the second network device through the third network, so that the second network device sends access selection information to the terminal, thereby enabling the terminal to successfully obtain the access selection information.

[0127] The access information transmission method provided in this application can be executed by an access information transmission device. This application uses an access information transmission device executing the access information transmission method as an example to illustrate the access information transmission device provided in this application.
