摘要
与传统地球静止轨道卫星相比,低轨道卫星具有大带宽、高通量、数据传输时延低等显著特点,更加适用于通信领域。低轨卫星通信系统与5G相互融合,取长补短,共同构建全球无缝覆盖的海、陆、空一体化综合通信网,满足用户无处不在的多种业务需求,是未来通信发展的重要方向。重点讨论了低轨卫星与5G网络融合架构、融合场景及融合内容,并重点分析了低轨卫星与5G网络融合所涉及的关键技术。
Compared with the traditional geostationary orbit satellite(GEO),low orbit satellite(LEO)is more suitable for application in the field of communication due to its significant characteristics such as large bandwidth,high throughput and low data transmission delay.LEO communication system and 5G will integrate with each other,learn from each other,and work together to build a seamless global integrated communication network covering sea,land and air,so as to meet users'ubiquitous multiple business needs,which is the important direction of future communication development.It focuses on discussing the fusion architecture,scene and content of LEO and 5G network and analyzing five key technologies involved in the fusion of LEO and 5G network.
