With the rapid development of satellite Internet,the integration and interoperability between low Earth orbit satellite core networks and terrestrial networks face significant challenges due to differences in technical systems,architectures,and operating environments.This paper investigates distributed satellite-ground integrated core network technologies,aiming to unify space,sky,and terrestrial networks into a single system.The proposed approach accommodates heterogeneous network access modes and common interoperability requirements across satellite-ground networks,utilizing the concept of distributed subnetworks to enable collaboration,division of labor,and interoperability between inter-satellite and satellite-ground networks at different stages of development.This novel model provides a new paradigm for the evolution of satellite Internet and has been initially applied in emergency communication scenarios.
