摘要
文中研究了能够为多样化应用提供定制化服务的卫星网络切片设计,基于5G技术提出了一种支持星地间网元的灵活部署的通用卫星端到端网络切片架构和切片技术方案。考虑到卫星资源有限和卫星信道特点,提出了卫星端到端网络切片架构,并对星地间网络功能的部署方案进行了综合设计;基于5G技术提出了支持无线网络资源按需分配的卫星子网切片技术;进一步研究了卫星端到端网络切片管理技术,包括切片KPI设计、切片部署和切片管理,为卫星网络切片技术的研究提供了参考。
In this paper,the slicing design of satellite network supporting customized services based on diversified applications is studie,and a novel and general satellite end-to-end(E2 E)network slicing architecture and slicing technology based on 5 G technology are proposed to support the flexible network deployment between satellite and ground.Considering the limited satellite network resources and satellite channel,a satellite end-to-end network slice architecture is proposed,and the network deployment scheme is comprehensively designed.Subsequently,the satellite network sub-slices technologies based on 5 g technology are proposed to support the on-demand allocation of wireless network resources.Then,we study the satellite E2 E network slice management technology,which provides a reference for the research of satellite network slicing technology.
