低轨道卫星网络基于网络切片的设计与实现

o solve the problems of insufficient flexibility and low resource utilization of LEO satellite network, an architecture using network slicing technology in 5G is proposed. Then a prototype system based on the Docker platform and DTN is implemented, providing IMS multimedia communication network slice, Internet of Things information collection network slice and web network slice. Tested by prototype system, the results show that each network slice can independently provide relevant service without affecting each other, and can be allocated network resources flexibly according to the performance requirements of the services. The design schema can effectively improve the flexibility of the core network of LEO satellite network.
