摘　　要： 随着无线网络技术的快速发展,怎样使用户正在进行的网络服务在用户移动过程中不被中断,使正在进行的服务能够在基站之间平滑过渡一直受到人们的广泛关注。设计一种高效、稳定的服务切换算法成为当前服务切换领域研究的热点问题。本文详细地介绍了现有部分服务切换算法和协议,以及相应算法的优点和缺点,并对服务切换算法进行了分类。文中对服务切换领域当前研究的现状进行了说明,并在讨论中介绍了今后的研究方向。 With the development of mobile communication,how to seamlessly transfer an ongoing call from one cell to another as a user moves through the coverage area of a cellular system becomes a serious problem.Handover is the mechanism to achieve the aim,and becomes one of the main issues in mobility.In this paper,a comprehensive survey on Handover is given,the advantages and application range of these arithmetic or schemes are discussed respectively,also the shortcomings and problems existed are anatomized in depth.It has been hoped that the illustration and discussion presented here would be helpful for developers in selecting an appropriate mobile handover arithmetic or protocol for their specific needs.In the end,the future trend of handover study is discussed.
