摘　　要：提出了一种基于虚拟小区的移动性增强算法,以实现超密集网络的移动性管理。首先设计了CU/DU分离架构,实现了控制面的集中优化,将集中管理节点部署在覆盖较广的宏小区,宏小区采用低频配置,确保移动过程中控制面信令连接的稳定性以及响应的实时性;然后设计了虚拟小区的资源管理模型,实现虚拟小区内小基站资源的最优化管理,通过集中管理节点有效协作虚拟小区内的小基站资源,最终达到提升用户体验的目的。A mobility enhancement algorithm based on virtual cell is proposed, thus to realize mobility management of ultra-dense networks. Firstly, the CU/DU separation architecture is designed to realize centralized optimization of the control plane. The centralized management node is deployed in a widecoverage macro cell, while the macro cell adopts low frequency configuration and ensures the stability and real-time response of the control plane signaling connection during the mobile process. Then, the resource management model of the virtual cell is designed to realize the optimal management of the small basestation resources in the virtual cell, and the centralized management node effectively cooperates with the small basestation resources in the virtual cell. And finally, the goal of improving the user experience is achieved.
