Research on 6G Satellite-Terrestrial Integrated Network Architecture

Abstract

With the advancement of 6G research, satellite-terrestrial integrated architecture has become a new important issue in the communications industry. This article first introduces the research status of satellite-terrestrial integrated architecture, including solutions proposed by international organizations such as 3GPP, ITU and ETSI. Then we proposed two block chain-based satellite-terrestrial integrated network security architectures. Finally, the article summarizes the development trend of satellite-terrestrial integrated network, and analyzes the challenges that the network faces in terms of resource coordination, management and unified access security.
