Architecture, technologies and experiment of satellite-terrestrial network based on space-based simplified core network

Abstract

Facing the future vision of ubiquitous network coverage, the deep integration and cooperative networking between satellite and terrestrial mobile communication network is a necessary technical path to build a space-air-ground integrated network, which can support access at anytime and anywhere. Firstly, current situation and development trend of space-air-ground integrated network were introduced. Then, the network architecture of satellite-terrestrial network and the design of space-based simplified core network were discussed, as well as the key technologies of satellite-terrestrial network. Finally, the proposed network architecture was verified by relevant experiments. and the follow-up research plan and outlook for future directions were discussed.
