摘要

低轨卫星系统凭借其全球覆盖、低时延等独特优势，结合星地直连的通信方式，在增强全球通信能力方面展现出巨大潜力，将成为下一代通信网络的重要组成部分。然而，该系统在移动性管理上面临诸多挑战，包括频繁的卫星切换、复杂的信令交互以及切换资源的分配管理等。为了推动低轨卫星移动性管理的发展，首先围绕架构设计、切换机制、业务连续性管理方面概述了近年来在该领域的相关进展，然后给出面向6G的低轨卫星移动性管理增强技术，最后探讨未来面临的机遇与挑战。

Abstract

The LEO satellite system

with its unique advantages such as global coverage and low latency

combined with the direct satellite-to-ground communication method

has shown great potential in enhancing global communication capabilities and will become an important part of next-generation communication network. However

the system faces many challenges in mobility management

including frequent satellite handovers

complex signaling interactions

and allocation and management of handover resources. To better advance the development of mobility management in LEO satellite communication systems

this paper first provided an overview of recent progress in mobility management related to architecture design

handover mechanisms

and traffic continuity management. It then presented mobility management enhancement technologies for 6G LEO satellite systems. Finally

this paper discussed the opportunities and challenges that future LEO satellite communication systems may face in mobility management.
