Architecture,technologies and experiment of satellite-terrestrial network based on space-based simplified core network
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 develop-ment 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 technolo-gies 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.
