Abstract
A method and a device for improving pipeline safety of a space-terrestrial network architecture. The method pre-registers the profile of a base station in the network repository function network element of a 5G core network; after receiving a relay pipeline connection establishment request initiated by a base station, a relay satellite sends a network function verification request to the network repository function network element through a network expose function network element; after receiving a response to a network function discovery request of the base station, the network expose function network element sets the corresponding verification result of the base station according to whether there is base station registration information and responds to a verification request of the network element; and finally, the relay satellite verifies the verification result cell carried in the received response to determine the legality of the current access to the base station.
