摘　　要：低轨卫星(Low Earth Orbital,LEO)通信网络是实现全球无缝覆盖的一种重要方式,是对地面通信网络的有效补充。但卫星与用户之间的相对高速运动造成了服务间断的问题,用户的移动性管理是低轨卫星通信系统运行的基础。分析了低轨卫星移动性管理的发展现状,并从决策因素对移动性管理性能的影响,海量用户、巨型星座的移动性管理,基于人工智能的智能管理等方面对其发展趋势进行了探讨。LEO(Low Earth Orbit)satellite communication network is an important way to achieve seamless global network coverage,which is an effective complement to terrestrial communication networks.However,the relatively high speed movement between LEO satellites and users causes the interruption of service.The mobility management of users is the basis of the LEO satellite communication systems operation.This paper analyzes the current development of mobility management of LEO satellite,and discusses its development trend from the aspects of the influence of decision-making factors on mobility management performance,mobility management for massive users and giant constellations,and intelligent management based on artificial intelligence.
