一种适应微蜂窝的移动性管理策略

在微蜂窝系统中，移动性管理是一个很重要的课题。如果采用传播蜂窝的位置登记的管理方式将会产生大量的系统资源浪费，降低系统的效率。本文提出一种基于用户移动特性（例如呼叫到达率、移动速度和移动位置等特点）的动态位置区的管理方案。在论文中对方案的寻呼代价和位置区修改代价进行分析和讨论，并与传统位置区管理方式〖１〗〖２〗做了比较。

A kind of mobility management strategy for microcellular system

The mobility management is a very important subject in microcellular systems If the method of the traditional macrocellular location management is adopted in the microcellular system,it will produce a lot of system resourses consumption and reduce the efficiency of the system This paper proposes a dynamic location management scheme based on the subscriber characteristics(such as call arrival rate,mobile terminal velocity and mobile position information) We analyse and discuss the paging cost and the location updating cost of this scheme in this paper,and compare it with the traditional location management
