5G与卫星网络融合演进研究

Research on the Evolution of Integrating Satellite and 5G Networks

卫星网络在覆盖、可靠性和灵活性等方面与地面5G网络具有融合互补的优势,3GPP和ITU等国际标准组织正在推进5G与卫星网络融合标准的制定。梳理归纳了5G与卫星网络的融合场景,分析了5G与卫星网络融合演进不同阶段的特征和组网问题,对融合演进涉及的核心网关键技术进行了研究,最后对5G与卫星网络融合演进的产业合作发展进行了展望。

Satellite networks have the advantages of integration and complementarity with terrestrial 5G networks in terms of coverage, reliability, and flexibility. International standard organizations such as 3GPP and ITU are promoting the standard formulation for the integration of 5G and satellite networks. This paper summarizes the integration scenarios of 5G and satellite networks, analyzes the characteristics and architecture of different integration evolution stages, and studies the corresponding key technologies in the core networks. Finally, the industrial cooperation development of 5G and satellite networks integration evolution is prospected.
