Exploration and Discussion on Key Technologies for Satellite-Terrestrial Integration Networking
For the future,mobile communication networks will have the ability to provide communication services with beyond connec-tivity,as well as to realize the system level integration of satellite communication and terrestrial communication,so an integrated satel-lite and terrestrial network architecture that included multiple elements such as connectivity,intelligence,sensing,computing,and data was proposed.Based on the proposed network architecture,several key technologies for satellite-terrestrial integration networking were discussed,included intelligent management and control technology for satellite and ground collaboration,a high dynamic network slic-ing technology for integrated satellite-terrestrial,and in response to the differentiated network service requirements of user services for integrated satellite and terrestrial network,the potential development patterns between distributed autonomous and network slicing tech-nologies were discussed.Then,onboard lightweight core network technology was introduced.Finally,the feasibility of multi-service network slicing coexistence and on-board lightweight core network were verified through a self-developed mobile communication net-work platform.
