摘要
随着毫米波通信、网络密集化、物联网等第五代(5G)网络新推动因素的引入,单位面积的基站数量,连接数急剧上升,使切换管理变得更具挑战性。5G中的移动性管理与传统网络(2G-4G)中的移动性管理截然不同。本文将介绍5G蜂窝网络中无线接入移动性背后的概念,还简要解释了5G系统中的移动状态程序,使其比传统系统更高效。
With the introduction of new enablers for fifth-generation(5G)networks,such as millimetre wave communications,network densification,Internet of things,etc.,Handover(HO)management is provisioned to be more challenging as the number of base stations(BSs)per unit area,and the number of connections has been dramatically rising.Mobility management in 5G is quite different from that of legacy networks(2G-4G)and in this section,the concepts behind the radio access mobility in 5G cellular network are presented.The mobility state procedures in 5G system that makes it more efficient than legacy systems are also briefly explained in this paper.
