[0049] This exemplary embodiment first provides a method for a terminal to access a network, which is applied to a terminal. Figure 1 As shown, the method for the terminal to access the network may include the following steps:

[0050] Step S110: Send a registration request to the network via the satellite, where the registration request carries proximity service capability parameters corresponding to the terminal.

[0051] The proximity service capability parameter includes a satellite access capability parameter, which is used to indicate the capability of the terminal to access the network via a satellite based on proximity service.

[0052] Step S120: Receive registration information of the terminal returned by the network based on the registration request of the terminal and the subscription data of the terminal.

[0053] The contract data includes information about the terminal's permission to access the network via a satellite based on proximity services.

[0054] Step S130: If the registration information returned by the network is registration acceptance, the terminal determines that it is authorized to use the satellite access network based on proximity service.

[0055] This exemplary embodiment also provides a method for a terminal to access a network, which is applied to a network end. Figure 2 As shown, the method for the terminal to access the network may include the following steps:

[0056] Step S210: Receive a registration request sent by the terminal via a satellite through the wireless access network, where the registration request carries proximity service capability parameters corresponding to the terminal.

[0057] The proximity service capability parameter includes a satellite access capability parameter, which is used to indicate the capability of the terminal to access the network via a satellite based on proximity service.

[0058] Step S220: Determine the registration information of the terminal according to the registration request of the terminal and the subscription data of the terminal through the access and mobility management function of the network.

[0059] The contract data includes information about the terminal's permission to access the network via a satellite based on proximity services.

[0060] Step S230: Return the registration information of the terminal to the terminal, so that the terminal determines whether it is authorized to use the satellite access network based on the proximity service according to the registration information.

[0061] In the method for terminal access to the network in the example implementation of the present disclosure, the terminal sends a registration request to the network via a satellite, and the registration request carries the proximity service capability parameters corresponding to the terminal, and the proximity service capability parameters include satellite access capability parameters, which are used to indicate the terminal's ability to access the network via a satellite based on proximity services; after the network receives the registration request sent by the terminal via a satellite, it determines the registration information of the terminal according to the registration request of the terminal and the contract data of the terminal and returns it to the terminal, and the terminal then determines whether it is authorized to use the satellite access network based on proximity services according to the registration information. The method for terminal access to the network in the example implementation of the present disclosure can realize the function of the terminal accessing the network via a satellite based on proximity services by expanding the proximity service capability parameters of the terminal, adding the ability of the terminal to access the network via a satellite based on proximity services, and carrying the indication of the corresponding service request through the registration process, further improving the integrated air-ground-space system, and providing users with a better user experience.

[0062] Next, combine Figure 3 to Figure 4 The above steps of this exemplary embodiment are described in more detail.

[0063] In step S110, a registration request is sent to the network via a satellite, and the registration request carries proximity service capability parameters corresponding to the terminal.

[0064] The proximity service capability parameter includes a satellite access capability parameter, which is used to indicate the capability of the terminal to access the network via a satellite based on proximity service.

[0065] Figure 3 The schematic diagram of the scenario architecture of a terminal accessing a network via a satellite according to a specific embodiment of the present disclosure is shown schematically. In this new satellite scenario, the ground terminal accesses the network via a satellite. Figure 3 The architecture shown is connected to the network. Figure 3 This is a new scenario, so it is necessary to authorize ProSe-based satellite access capabilities for terminals in this scenario.

[0066] In this example implementation, if the terminal indicates 5G ProSe Capability (5G proximity service capability) in the registration request message and authorizes the terminal to use 5G ProSe services based on subscription data, the AMF (Access and Mobility management Function) selects the PCF (Policy Control Function) that supports 5G ProSe Policy / Parameter provision (5G proximity service policy / parameter configuration), and establishes a UE (User Equipment) policy association with the PCF to issue 5G ProSe Policy / Parameter.

[0067] Among them, 5G ProSe Capability refers to whether the terminal supports one or more of the following ProSe capabilities:

[0068] -5G ProSe Direct Discovery; (5G ProSe Direct Discovery)

[0069] -5G ProSe Direct Communication; (5G Proximity Service Direct Communication)

[0070] -5G ProSe Layer-2 UE-to-Network Relay; (5G Proximity Service Layer-2 Network Repeater)

[0071] -5G ProSe Layer-3 UE-to-Network Relay; (5G Proximity Service Layer-3 Network Repeater)

[0072] -5G ProSe Layer-2 Remote UE; (5G ProSe Layer-2 Remote Terminal)

[0073] -5G ProSe Layer-3 Remote UE. (5G ProSe Layer-3 Remote Terminal)

[0074] In order to support Figure 3 The architecture scenario shown requires the ability to authorize the terminal to access the satellite, which can be achieved by extending the ProSe Capability.

[0075] In this example implementation, in the air-ground integrated communication network scenario, a method for authorizing satellite access to a terminal in the air-ground scenario is designed by carrying an indication of the corresponding service request through the registration process, further improving the air-ground integrated system. In the original registration process, by expanding the ProSe capability, the ability to access the network through a ProSe-based satellite is added.

[0076] In this example implementation, the indication information is the extended ProSe capability, that is, the ability to access the network through a ProSe-based satellite is added. The remote terminal / relay terminal sends a registration request to the (R)AN (Radio Access Network) via a satellite, and carries the ProSe capability (proximity service capability) parameter in the registration request message. The ProSe capability is used to indicate the capability of the terminal. By extending the ProSe capability, the ability to access the network through a ProSe-based satellite is added, such as ProSe satellite Relay (proximity service satellite relay) / ProSe satellite Remote UE (proximity service satellite remote user equipment).

[0077] In step S120, registration information of the terminal returned by the network based on the registration request of the terminal and the subscription data of the terminal is received.

[0078] In this example implementation, after the terminal sends a registration request carrying the proximity service capability parameters corresponding to the terminal, it waits to receive the terminal registration information returned by the network based on the terminal registration request and the terminal subscription data. The subscription data includes the terminal's permission information to access the network via a satellite based on proximity service.

[0079] In step S130, if the registration information returned by the network is registration acceptance, the terminal determines that it is authorized to use the satellite access network based on proximity service.

[0080] If the registration information returned by the network is registration acceptance, the terminal determines that it is authorized to use the satellite access network based on proximity service, and the terminal can access the satellite based on ProSe.

[0081] In step S210, a registration request sent by a terminal via a satellite is received via a wireless access network, where the registration request carries proximity service capability parameters corresponding to the terminal.

[0082] The proximity service capability parameter includes a satellite access capability parameter, which is used to indicate the capability of the terminal to access the network via a satellite based on proximity service.

[0083] In this example implementation, after receiving a registration request sent by a terminal through a wireless access network, a corresponding access and mobility management function is selected according to a proximity service capability parameter corresponding to the terminal carried in the registration request.

[0084] (R)AN can select AMF based on the information carried in the registration request message, and then send a registration request to AMF. (R)AN can send an N2 message (N2 interface is the interface between (R)AN and AMF) to AMF, including N2 parameters and registration request.

[0085] In step S220, the registration information of the terminal is determined according to the registration request of the terminal and the subscription data of the terminal through the access and mobility management function of the network.

[0086] The contract data includes information about the terminal's permission to access the network via a satellite based on proximity services.

[0087] In this example implementation, when the registration information of the terminal is determined through the access and mobility management function of the network, if the contract data of the terminal does not exist in the access and mobility management function, the contract data is obtained from the unified data management function and stored as part of the context data of the terminal.

[0088] After the AMF successfully completes the registration operation and there is no subscription data about the remote terminal / relay terminal, the AMF will obtain the terminal's subscription data about ProSe access to the satellite from UDM (Unified Data Management) through a subscription data acquisition operation, for example: subscription for Remote UE to connect U2Nrelay via satellite access (the remote terminal connects to the network via the satellite access of the relay terminal). The subscription information in UDM contains information that grants the user the right to access the satellite via ProSe. The AMF can obtain the terminal's subscription data about ProSe access to the satellite from the UDM and store them as part of the UE context data.

[0089] Then, the AMF can determine whether the terminal is authorized to use ProSe-based satellite access based on the ProSe capability of the terminal and the contract data received from the UDM containing the permission information for accessing the satellite via ProSe. Then, the terminal can access the satellite based on ProSe, for example, authorizing the remote terminal to connect to the network via the satellite access of the relay terminal.

[0090] In this example implementation, in response to a modification operation or a deletion operation on subscription data in a unified data management function, permission information for a terminal to access a network via a satellite based on proximity service may be modified or deleted.

[0091] The operator may modify or delete the user subscription rights for accessing satellites via ProSe in the contract information in the UDM at any time, or revoke the user subscription rights for accessing satellites via ProSe.

[0092] When the subscription data of the terminal in the unified data management function changes, the changed subscription data will be resent to the access and mobility management function on the network side, so that the access and mobility management function will re-determine the registration information of the terminal based on the terminal's registration request and the subscription data of the terminal.

[0093] After receiving the response of successful subscription data acquisition, AMF can subscribe to the service of receiving notification when the subscription data is modified. When the subscription data about the terminal in UDM changes, UDM will resend the changed subscription data to the access and mobility management function on the network side.

[0094] In step S230, the registration information of the terminal is returned to the terminal, so that the terminal determines whether it is authorized to use the satellite access network based on the proximity service according to the registration information.

[0095] Finally, the AMF sends registration information to the UE. If the registration information is registration accepted, the terminal can access the network based on the ProSe satellite.

[0096] like Figure 4 The figure is a complete flowchart of a terminal authorizing a ProSe-based satellite access network in a specific implementation manner of the present disclosure, which is an example of the above steps in this example implementation manner. The specific steps of the flowchart are as follows:

[0097] Step S410. The remote terminal / relay terminal sends a registration request via satellite.

[0098] The remote terminal / relay terminal sends a registration request to the (R)AN via satellite and carries the ProSe capability (Proximity Service Capability) parameter in the registration request message. ProSe capability is used to indicate the capability of the terminal. By extending the ProSe capability, the ability to access the network through a ProSe-based satellite is added, such as ProSe satellite Relay (satellite relay) / ProSe satellite Remote UE (satellite remote user equipment).

[0099] Step S420. (R)AN selects AMF based on the registration request.

[0100] The (R)AN selects an AMF based on the information carried in the Registration Request message.

[0101] Step S430. (R)AN sends a registration request to AMF.

[0102] (R)AN sends a registration request to AMF, for example, sending an N2 message (N2 parameters, registration request).

[0103] Step S440a. AMF obtains the terminal's subscription data regarding ProSe access to the satellite.

[0104] After the AMF successfully completes the registration operation and there is no subscription data about the remote terminal / relay terminal, the AMF will obtain the terminal's subscription data about ProSe access to the satellite from the UDM through the subscription data acquisition operation, for example: subscription for Remote UE to connect U2N relay via satellite access (the remote terminal connects to the network via the satellite access of the relay terminal).

[0105] The subscription information in the UDM contains information granting the user the right to access the satellite via ProSe. The operator can modify or delete the user's subscription rights for accessing the satellite via ProSe in the subscription information in the UDM at any time, or revoke the user's subscription rights for accessing the satellite via ProSe.

[0106] Step S440b. UDM returns the terminal's subscription data about ProSe access to the satellite.

[0107] The AMF obtains the terminal's subscription data about ProSe access to the satellite from the UDM and stores them as part of the UE context data.

[0108] Step S440c. AMF subscribes to the service to receive notification when the contract data is modified.

[0109] After receiving a response that the contract data has been successfully obtained, the AMF can subscribe to a service to receive notifications when the contract data is modified.

[0110] Step S450. The AMF determines whether the terminal is authorized to use ProSe-based satellite access.

[0111] The AMF determines whether the terminal is authorized to use ProSe-based satellite access based on the ProSe capability of the terminal and the subscription data received from the UDM containing the permission information for accessing the satellite via ProSe, for example, authorizing the remote terminal to connect to the network via the satellite access of the relay terminal.

[0112] Step S460. AMF sends a registration acceptance to the terminal.

[0113] If the AMF sends a registration acceptance to the UE, the terminal can access the ProSe-based satellite.

[0114] It should be noted that although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.
