摘　　要：为了在寻呼时能够快速准确地找到通信对端的接入卫星,需要对卫星网络的用户终端进行有效的移动性管理。提出了一种改进的动态虚拟化移动性管理方案。对于无法修建地面站的位置区,采用基于地面用户密度的自适应生成虚拟网关方法,可减少用户位置管理开销,并可实现大规模星座下的移动性管理。In order to accurately find the access satellite of the communication peer during the process of paging,effective mobility management of user terminals connected in the satellite network is required.An improved dynamic virtualized mobility management scheme is proposed.For location areas where ground stations cannot be built,a method of adaptively generating virtual gateways based on ground user density is proposed to re-duce user location management overhead,and finally achieve large-scale constellation simulation of mobility management solutions.
