Key technical research of space-terrestrial integrated network based on satellite-terrestrial collaborative networking
With the rapid development of space-terrestrial integrated communication technologies,the satellite and ter-restrial cellular communication industry ecosystems are gradually converging to meet the needs of ubiquitous broad-band 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 in-tegrated 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.
