5G移动通信系统将提供独立于无线技术的移动性管理，无论用户位置如何改变，都能确保业务和通信质量的 连续性。本文首先分析了5G移动通信系统在移动性管理的设计目标：低时延、低功耗、高可靠性和灵活性；其次，分析了5G移 动性管理的三个主要场景，分别是分布式移动性管理场景、集中式移动性管理场景、分布集中混合式场景；最后，对5G移动性 管理的网络控制切换和终端自动控制切换两种解决方案进行了对比分析。

5G mobile communication system will provide mobility management independent of wireless technology, and can ensure the continuity of business and communication quality, no matter how the user's location changes. This paper first analyzes the design objectives of 5G mobile communication system, such as low latency, low power consumption, high reliability and flexibility. Secondly, the three main scenarios of 5G mobility management are analyzed, which are distributed mobility management scenario, centralized mobility management scenario, distributed centralized hybrid scenario. Finally, the two solutions of 5G mobility management network control switch and terminal automatic control switch are compared and analyzed.
