Abstract: A method of signaling interaction in 5G space-ground integrated heterogeneous network architecture is provided, which enables publicly available data for trusted satellite discovery to be registered to the 5G core network based on the function framework of the 5G core network. When searching for satellites, a gNB can utilize the publicly available data of the trusted satellite registered in the 5G core network to speed up satellite searching, improve satellite link services, and filter out untrusted satellites. By the method provided by the present disclosure, it can effectively improve the satellite search speed in the 5G space-ground integrated architecture, improve satellite link availability, reduce authentication complexity of satellites in ground networks in heterogeneous network architecture.
