Abstract:

Based on the reviews of standardizations and many other works of 5G-satellite integrated network (5GSIN), the research progress of 5GSIN key technologies, applications and network architectures were expounded and analyzed.Aiming at the key problems caused by the strong heterogeneity and large spatio-temporal scale of 5GSIN, the multi-layer distributed network architecture was proposed, and the architecture management method was designed.Finally, several key directions of the future development of 5GSIN were analyzed from the perspective of intelligence, in order to provide some references for research in related fields.

Key words: integrated network, heterogeneous network, architecture, MEC, NFV, intelligent network
