摘要

摘要: 在第五代移動(dòng)通信(5G)系統(tǒng)中，大規(guī)模MIMO天線和超密集部署網(wǎng)絡(luò)是實(shí)現(xiàn)高吞吐量的兩種方式。針對(duì)超密集網(wǎng)絡(luò)的切換管理的問題，該文基于網(wǎng)絡(luò)分簇的思想提出了根據(jù)終端設(shè)備運(yùn)動(dòng)情況動(dòng)態(tài)調(diào)節(jié)滯后余量的切換管理算法。在該算法中，基于小基站分簇化管理的前提，用戶設(shè)備在小區(qū)間切換分為預(yù)切換和正式切換兩個(gè)階段，預(yù)切換階段完成最佳目標(biāo)小區(qū)選擇、小區(qū)資源預(yù)留和預(yù)鑒權(quán)等操作，正式切換階段根據(jù)預(yù)切換階段監(jiān)測(cè)的設(shè)備速度動(dòng)態(tài)調(diào)節(jié)切換門限的滯后余量。仿真結(jié)果表明了該算法可以有效降低設(shè)備的切換時(shí)延和切換失敗率。

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.
