Abstract

With the rapid development of space-terrestrial integrated communication technologies

the satellite and terrestrial cellular communication industry ecosystems are gradually converging to meet the needs of ubiquitous broadband communication. In order to achieve efficient collaboration between satellite and terrestrial networks in terms of coverage

resources and scheduling

and improve the overall network performance

satellite-terrestrial collaborative networking will be an important direction of space-terrestrial integrated network in the future. Aiming at the goal and vision of space-terrestrial integrated network

the development status and technical challenges of space-terrestrial integrated network were explained

and the satellite-terrestrial integrated network architecture and technical system based on satellite-terrestrial collaborative deployment were proposed innovatively. The key technical schemes of satellite-terrestrial network collaboration at beam-level

service-level and planning-level were analyzed deeply

which provided guidance for the following research on satellite-terrestrial network collaboration technology.
