When the terminal device accesses the 5G core network by using a 5G satellite mode, the UE first sends a first registration request message to a first AMF (Access and Mobility Management Function) network element in the 5G core network through a satellite Access network.
In this example embodiment, the first registration request includes: the GNSS positioning capability, the 5G network access capability and the 5G network coverage condition of the terminal equipment, and the first position information obtained based on the GNSS positioning.

Specifically, for the 5G core network, after receiving the first registration request message of the UE, the first AMF network element registers with a UDM (Unified Data Management) network element, and performs user authentication. For the network side, the GNSS location information actively reported by the UE is not completely trusted, and the determination is performed according to the capability information and the location information carried in the first registration request information uploaded by the UE. And if the UE supports 5G access and is covered by a 5G network, the UE is subjected to position verification by adopting UE position information positioned by the ground 5G network, and at the moment, the first AMF network element returns a registration acceptance message to the UE and indicates that the UE is requested to be accessed through the ground 5G access. Or, when it is determined that the UE does not support 5G access or does not have 5G network coverage according to the capability information and the location information carried in the first registration request information, using the GNSS location information of the UE to verify whether the UE is in a legal operating area.
In step S12, after receiving the registration acceptance message fed back by the first AMF network element, the terminal device sends a second registration request message including second location information of the terminal device to a second access and mobility management function AMF network element through a terrestrial access network, so as to trigger the first AMF network element to obtain the second location information and perform verification.
In this exemplary embodiment, the registration acceptance message fed back by the first AMF network element may carry indication information indicating that the UE is requested to access through the terrestrial 5G access.

the second AMF network element registers to a unified data management function (UDM) network element, and the second position information is stored to the UDM network element;
and the UDM network element sends the second location information to the first AMF network element so that the first AMF network element verifies the second location information.
In this embodiment, after the second AMF network element registers with a UDM network element, the method further includes:
and the terminal equipment receives the registration rejection message sent by the second AMF network element.
Specifically, the second AMF network element registers with the UDM network element and performs user authentication. The UDM network element stores the 5G location information of the UE received from the second AMF network element. And then, the second AMF network element sends a registration rejection message to the UE, and the reason value is to indicate the satellite access position verification. The UDM network element provides the 5G position information of the UE to a first AMF network element registered by satellite access; and the first AMF network element verifies whether the UE is allowed to be used at the current position according to the 5G position of the UE received from the UDM network element.
In this exemplary embodiment, when the terminal device does not have an access capability of a 5G network, or currently there is no 5G network coverage, the method further includes:
and receiving a verification result of the first AMF network element on the first position information.
Specifically, the UDM network element determines the terminal capability information and the location information carried in the first registration request message. And if the UE does not support 5G access or does not have 5G network coverage, verifying whether the UE is in a legal operating area or not by adopting the GNSS position information of the UE. And if the UE is verified to be in the legal operation area, allowing the UE to access the 5G network and providing 5G network service for the UE. Or if the UE is verified to be in the illegal operation area, the 5G network service is refused to be provided for the UE, and the position verification result is fed back to the UE.
In addition, in some exemplary embodiments, after the network side verifies that the UE is in the legal operation area only by using the GNSS location information and provides the 5G network service to the terminal device, the network side may also actively initiate a location information request to the terminal device after a preset duration to request the UE to provide the location information to the network side again, so that the network side verifies whether the UE is in the illegal operation area again; and determining whether to continue providing the 5G network service for the UE according to the position verification result.

At this time, the first AMF network element returns a registration acceptance message to the UE and indicates to request the UE to access through the terrestrial 5G access network.
After receiving a second registration request message sent by the UE through the terrestrial 5G access network, the second AMF network element sends the 5G location information of the UE to the second AMF network element in the NGAP message by the terrestrial 5G access network. And the second AMF network element registers to the UDM network element for user authentication. The UDM stores 5G location information of the UE received from the second AMF network element. And the second AMF network element sends a registration rejection message to the UE, and the reason value is to indicate the satellite access position verification. Synchronously, the UDM network element provides the 5G position of the UE to the first AMF network element of the satellite access registration. And the first AMF network element verifies whether the UE is allowed to use the 5G network service at the current position according to the 5G position of the UE received from the UDM network element.
