Abstract: To solve the problems of insufficient flexibility and low resource utilization of the core network of space-ground integrated network, an architecture design scheme using network slicing technol- ogy in 5G is proposed. Then, a prototype system based on the Docker platform is implemented. Three slicing services such as IMS multimedia communication network, Internet of Things information collection network, and web network are loaded on the prototype system for testing. The results show that different network slices can flexibly allocate network resources and independently provide services. The design scheme can effectively improve the networking flexibility of the core network of the space-ground integrated network.
