As shown in fig. 2, the embodiment of the present application provides an access information transmission method, where the execution body of the method is a first network device, in other words, the method may be executed by software or hardware installed in the first network device. The method comprises the following steps.

S210, the first network equipment acquires first information, wherein the first information is used for indicating access selection information of the first network.

The first Network device may be a Network device having an application function (Application Function, AF) of the first Network, and specifically may be an application function entity in the first Network, where the first Network is a Network that provides a local service for the terminal, and may also be referred to as a nesting Network, for example, may be a Stand-alone Non-Public Network (SNPN) or a Public Network integrated Non-Public Network (Public Network Integrated Non-Public Network, PNI-NPN).

The second network device is a network device with a unified data management function of the second network, and specifically may be a unified data management entity (Unified Data Management, UDM) or a unified data repository (Unified Data Repository, UDR) of the second network, where the second network is a Home network of the terminal, and may also be referred to as a Home network.

For simplicity, in the following embodiments, the first network is a nesting network, the first network device is an AF1, the second network is a Home network, and the second network device is a UDM2 for example.

The terminal may sign up with the local service provider according to actual requirements, such as purchasing tickets, signing up online, etc. The subscription procedure may be accomplished using a mobile network or may be accomplished through a network other than the 3GPP protocol (out of 3GPP scope).

Through the subscription procedure, the local service provider may obtain an identification (UEID) of the terminal, a subscribed local service list (List of Local service), etc.

After the subscription with the terminal is completed, the local service provider notifies the first network to complete the subscription with the terminal, so that the first network equipment obtains the first information.

Optionally, the first information includes at least one of:

the identification of the terminal;

access selection information of the first network;

and a local service list of the terminal.

Optionally, the access selection information of the first network may include at least one of:

the network identifier of the first network, namely the network identifier of the nesting network;

and the local service corresponds to the relevant information.

In another embodiment, the first network may also negotiate with a second network and store a local service list supported by the first network in the second network, where each of the local service lists may include a reference identifier (reference ID) and local service identification information, and related information corresponding to the local service, such as slice information, DNN, and the like. Wherein, the reference identifier may be local service identification information. The first network device instructs the second network device to acquire relevant information corresponding to the local service corresponding to the reference identifier or the local service identifier information from the local service list through the second information. In this case, the second information may include at least one of an identification of the terminal, a reference identification, identification information of the local service, and access validity condition information.

After the second network device obtains the access selection information of the first network according to the second information, optionally, the second network device may update the subscription information of the terminal according to the access selection information.

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 may access the first network according to the access selection information and obtain a local service provided by the first network. Wherein the access selection information of the first network may include: the network identification of the first network, the access effective condition information, the identification information of the local service and the relevant information corresponding to the local service.

As can be seen from the technical solutions of the foregoing embodiments, in the embodiments of the present application, first information is obtained, where the first information is used to indicate access selection information of a first network; and then sending second information to second network equipment, wherein the second information is used for indicating the access selection information of the first network so that the second network equipment can send the access selection information of the first network to the terminal, and the terminal can successfully acquire the access selection information.

Based on the above embodiment, as shown in fig. 3, in one implementation manner, the method for transmitting access selection information includes the following steps.

S310, the terminal UE signs up with AF0 of the local service provider LSP, and can acquire the UEID, the signed List of local service and the like through the signed LSP.

S320, the AF0 informs the Hosting network that the terminal has completed signing through a network opening function (Network Exposure Function, NEF) NEF1 of the Hosting network, so that the AF1 acquires the first information.

S330. The AF1 sends second information to the UDM2 through NEF2 of the Home network for sending access selection information, UEID and the like of the Hosting network to the UDM 2.

S340, the UDM2 sends access selection information of the nesting network to the UE.

The steps S320 and S330 may implement the method embodiments of steps S210 and S220 in fig. 2, and obtain the same technical effects, and the repetition is repeated here.

In one embodiment, as shown in fig. 4, the step S320 includes:

s322, after the UE successfully completes subscription with the LSP, the AF0 sends a first message to the third network device through the NEF1, wherein the first message is used for indicating the local service provider to complete subscription with the terminal. The first message may specifically be a local service subscription success message.

The first message carries at least one of:

the identification of the terminal;

access selection information of the first network;

and a local service list of the terminal.

The third network device is a network device with a unified data management function of the nesting network, and may specifically be a unified data management entity or a unified data repository, and for simplicity, the following embodiments take the third network device as a UDM1 for illustration.

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

The local service subscription information includes at least one of:

the identification of the terminal;

the access selection information of the nesting network;

and a local service list of the terminal.

In an embodiment, the access selection information of the nesting network may also be obtained from the AF 1. AF1 stores the relevant information of the access selection information in advance. The local service subscription information sent by the UDM1 to the AF1 comprises the identification of the terminal and/or a local service list of the terminal. And the AF1 acquires the access selection information of the nesting network from the stored related information according to the identification of the terminal and/or the local service list of the terminal.

Optionally, as shown in fig. 4, the method further includes, before step S322:

s321, the AF1 sends a subscription request to the UDM1, wherein the subscription request is used for subscribing the local service subscription information subscribed by the terminal to the UDM 1.

The manner in which the UDM1 transmits the access selection information to the terminal in step S340 may be varied, and may be through a terminal parameter update (UEParameter Update, UPU) procedure or a roaming guidance (Steering of Roaming, soR) procedure. If a UPU process is adopted, the access selection information of the nesting network can be contained in a UPU container (UPU container) and transmitted to the UE; if the SoR procedure is adopted, the access selection information of the nesting network may be contained in a SoR container (SoRcontainer) and transmitted to the UE.

If the terminal is not currently in the first network, the UDM1 needs to transmit the access selection information to the terminal through a third network. The third Network is a mobile Network that currently serves the terminal, which may also be referred to as a Serving Network, and may be, for example, a Non-Public Network (NPN) or a Public land mobile Network (Public Land Mobile Network, PLMN).

In one embodiment, as shown in fig. 5, the step S340 may include the following steps.

S341, the UDM2 may determine to trigger the UPU procedure or the SoR procedure after obtaining the second information.

S342, UDM2 sends a data management Notification message, for example, a subscription data management Notification message (Subscription Data Management Notification, SDM Notification), which may be expressed as nudm_sdm_notification, to an access and mobility management function (Access and Mobility Management Function, AMF) AMF3 of the Serving network. The data management notification message comprises access selection information of the nesting network, and if a UPU process is triggered, the data management notification message is contained in a UPUcontact; if a SoR procedure is triggered, it is included in the SoR container.

S343, AMF3 sends a downlink message to the terminal, wherein the downlink message comprises the access selection information of the Hosting network. The downstream message may be a downstream non-access stratum transport message (DownLinkNon Access Stratum TRANSPORT, DLNASTRANSPORT).

According to the technical scheme of the embodiment, the access selection information is sent to the terminal by triggering the UPU process or the SoR process, so that the terminal can successfully acquire the access selection information.

Based on the above embodiment, there may be a protocol (agreement) between two Home network, nesting network, and LSP, and all three may directly provide the UE with network selection information for accessing the nesting network. However, if there is no protocol between the Home network and the nesting network, the forwarding needs to be performed by using the Serving network.

In one embodiment, as shown in fig. 6, the access information transmission method includes the following steps.

S410, the terminal signs up with AF0 of local service provider LSP.

S420, the AF0 informs the nesting network that the terminal has completed signing through the NEF1, so that the AF1 acquires the first information.

S431-S432, in the case where there is no protocol between the second network and the first network, the AF1 sends second information to the UDM2 through a third network, specifically including, as shown in fig. 6: the AF1 sends second information to the UDM2 through a fourth network device, where the fourth network device is a network device having an application function in the third network, and may specifically be an application function entity AF3.AF1 sends the second information to AF3 via NEF3, which is then sent by AF3 to UDM2 via NEF 2.

S440, UDM2 sends access selection information to the UE.

Steps S410 to S440 may implement the method embodiments of steps S310 to S340 shown in fig. 3, and obtain the same technical effects, and the repetition of which is not repeated here.

In the signing process of step S410, the LSP also needs to acquire the network identifier (Serving Network ID) of the Serving network where the terminal is currently located, and inform the Serving network terminal of the current Serving network, so that the Serving network may send the access selection information of the Serving network to the Serving network in step S431.

The manner in which the LSP obtains the ServingNetwork ID may be that the terminal directly sends ServingNetwork ID to the AF0 in step S410, or that the LSP obtains the Serving network where the terminal is located according to the identifier of the terminal.

In one embodiment, the first information in step S420 may further include the ServingNetwork ID; accordingly, the ServingNetwork ID may also be included in the second information of the S431 to S432.

As can be seen from the technical solutions of the foregoing embodiments, in the embodiments of the present application, when no protocol exists between the second network and the first network, second information is sent to the second network device through the third network, so that the second network device sends access selection information to the terminal, and therefore the terminal can successfully obtain the access selection information.
