面向6G的星地融合网络架构

Integrated Satellite and Terrestrial Network Architecture for 6G

通过对卫星星座的发展和星地融合网络研究的回顾,明确了6G的星地融合网络的发展趋势,提出了智简赋能的6G网络体系架构和弹性可重构的6G星地融合架构,并分析了星地融合网络中的关键技术问题,包括星上轻量化虚拟化技术、星上边缘计算功能以及广播/多播技术。认为6G星地融合网络将通过星地协同实现网络资源和计算资源的统一调度,同时可以根据业务需求和网络状态智能实现网络功能的按需弹性部署。

Through a review of the development of satellite constellations and research on the integrated satellite and terrestrial networks,the trend of the integrated satellite and terrestrial networks for 6G is put forward.An intelligent simplicity empowerment 6G network architec⁃ture and a resilient and reconfigurable integrated satellite and terrestrial architecture are proposed.Then the key technical issues in the inte⁃grated satellite and terrestrial networks,including lightweight virtualization technology onboard satellites,onboard edge computing function,and broadcast/multicast technology are analyzed.It is believed that 6G integrated satellite and terrestrial networks will achieve unified sched⁃uling of network and computing resources through satellite-terrestrial cooperation and can intelligently deploy network functions flexibly ac⁃cording to service requirements and network conditions.
