Network Slicing Technology of Integrated Satellite and Terrestrial Network

Satellite-terrestrial integration networks, marked by high dynamics, resource restrictions, and mobility, pose challenges in network slicing like integration, scalability, and automated construction. This paper presents an intelligent orchestration architecture for network slicing in satellite-terrestrial integration networks. On this basis, three key technologies: slice intelligent orchestration, computing and networking resource scheduling orchestration, and service-resource knowledge graphs are designed. Finally, a satellite-terrestrial integration experiment platform is built. Tests on three typical business scenarios show the effectiveness of the proposed technology. Results indicate that the architecture and key technologies can enhance resource utilization and business response speed in satellite-terrestrial integration networks, meeting diverse scenario demands and strongly supporting the intelligent management and development of 6G networks.
