Abstract

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.
