1. A method for improving pipeline safety of a space-terrestrial network architecture, comprising:
step S1, when a legal base station is connected to a 5G core network or a network repository function network element updates a profile of a network function network element based on manual configuration, pre-registering a profile of a base station in the network repository function network element of the 5G core network;
step S2, after receiving a relay pipeline connection establishment request initiated by the base station, initiating, by a relay satellite, a network element verification request carrying the profile of the base station to a network expose function network element based on the profile of the base station in the relay pipeline connection establishment request, and sending a network function search request to the network repository function network element through the network expose function network element;
step S3, after receiving the network function search request, returning, by the network repository function network element, a base station query result to the network expose function network element according to a registration information; and when the registration information of the base station exists, setting a verification result in a verification result cell as “REGISTERED” by the network expose function network element; and otherwise, setting the verification result as “NOT EXIST”, and responding to the network element verification request of the relay satellite; and
step S4, responding and checking, by the relay satellite, the carried verification result cell according to the received network element verification request,
when the verification result cell carries the verification result of “REGISTERED”, accepting the relay pipeline connection establishment request of the base station; and
when the verification result cell carries the verification result of “NOT EXIST”, rejecting the relay pipeline connection establishment request of the base station.
