摘要

摘要: 在第五代移动通信(5G)系统中，大规模MIMO天线和超密集部署网络是实现高吞吐量的两种方式。针对超密集网络的切换管理的问题，该文基于网络分簇的思想提出了根据终端设备运动情况动态调节滞后余量的切换管理算法。在该算法中，基于小基站分簇化管理的前提，用户设备在小区间切换分为预切换和正式切换两个阶段，预切换阶段完成最佳目标小区选择、小区资源预留和预鉴权等操作，正式切换阶段根据预切换阶段监测的设备速度动态调节切换门限的滞后余量。仿真结果表明了该算法可以有效降低设备的切换时延和切换失败率。

Abstract: In the fifth generation (5G) mobile communication system, massive MIMO antenna and ultra dense deployment of the network are the two ways to achieve high throughput. To solve the mobility management problems in ultra dense clustering network, this paper presents a handover management algorithm that adjusts the hysteresis margin according to the movement of terminal equipment. In this algorithm, the handover is divided into pre-handover and official handover after clustering small base stations. The pre-handover helps to select the best target cell, complete resource reservation and pre-authentication. During the official handover, hysteresis margin of the handover threshold is adjusted according to the speed of the device. Simulation results show that it can effectively reduce the handover delay and probability of handover failure.
