摘　　要：切换是下一代蜂窝通信网络的关键方面之一,需要妥善管理,因为它对服务质量(QoS)构成多重威胁,例如平均吞吐量的降低和服务中断。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。为此已经提出并测试了智能切换管理方案,为更有效地应对这些挑战铺平了道路。本文介绍了5G NR中的双连接,NR中的切换管理和切换过程,B5G中的移动性和切换管理。Handover(HO)is one of the key aspects of next-generation(NG)cellular communication networks that need to be properly managed since it poses multiple threats to quality-of-service(QoS)such as the reduction in the average throughput as well as service interruptions.With the introduction of new enablers for fifth-generation(5G)networks,such as millimetre wave communications,network densification,Internet of things,etc.,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.To this end,intelligent HO management schemes have been proposed and tested in the literature,paving the way for tackling these challenges more efficiently and effectively.In this paper,the dual connectivity in 5G NR,handover management and handover process in NR,mobility and handover management in B5G are introduced.
