摘要/Abstract

摘要：

对6G网络中的卫星通信接入和移动性管理技术进行了分析和展望。首先介绍了目前全球有代表性的卫星移动通信系统接入技术体制，以及国际标准化机构对5G NR卫星接入技术的研究现状，然后根据6G卫星通信网络接入所面临的挑战，分别从极简接入和极智接入两个方面探讨潜在的6G卫星通信网络接入技术。此外，还从6G卫星通信的高动态场景下的海量终端切换需求出发，提出了基于云通道技术的海量终端跨星跨波束批量柔性切换的移动性管理方案建议。

关键词: 6G卫星通信, 接入技术, 移动性管理, 极简接入, 极智接入

Abstract:

Analsisand outlook for satellite communication access and mobility management technology in 6G network was presented.Firstly, the access technology of current global representative satellite mobile communications system was introduced, as well as the international standardization organization research status of 5G NR satellite access technology.According to the challenges for 6G satellite communications network access, some solutions regarding to 6G satellite communications access were proposed respectively from the aspects of extremely simple access, extremely intelligent access.Furthermore, according to the demand of massive terminals handoff in the high dynamic scenario of 6G satellite communications, the flexible handoff scheme based on cloud channel technology, which supported batch massive terminals mobility management for across satellites and beams, was proposed.

Key words: 6G satellite communication, access technology, mobility management, extremely simple access, extremely intelligent access
