摘要
随着地面移动通信网络从信息随心至的5G时代,迈向万物互联的6G时代,卫星网络逐渐成为世界各国发展热点。与此同时,随着星上计算能力提升,星上计算技术与卫星网络技术融合,云网融合成为新的发展趋势。在简要介绍卫星网络、星上计算发展现状的基础上,系统梳理卫星网络发展架构的路线图,提出一种云网融合的卫星网络体系架构,简称卫星云网,并从通信接入、网络传输、服务、控制、管理等5个方面分析卫星云网体系架构相较于传统卫星网络体系架构的优势。
With the public land mobile communication network transitioning from the 5G era where information flows freely to the 6G era where everything is interconnected,satellite networks have become a hot development topic all around the world.At the same time,with the improvement of satellite on-board computing capabilities and the integration of computing and satellite networks,cloud network integration has become a new development trend.On the basis of a brief introduction to the current development status of satellite networks and satellite computing,the development roadmap of satellite network development architecture was summarized.Then,a satellite network architecture based on cloud-network integration(i.e.satellite cloud network)was proposed,and the advantages of satellite cloud network architecture from five aspects:computing driven communication enhancement,computing driven network enhancement were analyzed,computing driven service enhancement,computing driven control enhancement,and computing driven management enhancement.
