6G卫星物联网移动性管理:挑战与关键技术

Mobility management of the 6G satellite IoT: challenges and key techniques

卫星物联网是面向6G的新一代物联网的重要构成部分,是实现"泛在连接"愿景的重要网络形态。移动卫星与终端之间的相对高速运动引起了服务连续性问题。阐述了卫星物联网移动性管理技术,分析了双移动、广域覆盖以及需求非均匀等因素给卫星物联网移动性管理带来的新挑战,从移动性管理架构、预测及增强等方面探讨了面向6G卫星物联网移动性管理的关键技术。

The satellite Internet of things(SIoT)is regarded as a feasible scheme to realize the vision of the"ubiquitous connection"in 6G.The relatively high-speed movement between the mobile satellite and the terminal causes service continuity problems.The mobility management technology of the SIoT was expounded.New challenges to the mobility management of the SIoT caused by the dual-mobility,wide-area coverage and non-uniform demand were analyzed.Key techniques of the mobility management of the SIoT in 6G from aspects of the mobility management architecture,prediction and enhancement were discussed.
