一种基于状态的动态位置管理方法

在蜂窝移动通信系统中,用户位置管理方法性能的好坏直接影响系统的服务质量.本文提出了一种基于运动状态的动态位置管理方法.系统根据用户不同的运动状态动态地决定其位置区的大小.其性能较传统方法有显著提高,接近基于个体移动特征的方法;同时,它保持了传统算法实现简单的特点,不增加任何系统负担,不改变现有的信令流程,较好地兼顾了性能与工程实用性两方面的要求,适合3G系统的应用要求,具有很好的工程应用前景.

A Dynamic Location Management Scheme Based on Movement-State

In cellular mobile communications system,the performance of location management scheme has great influence on the service quality of system.This paper proposes a state-based dynamic location management scheme.In which,the location area size is decided according to the user's movement state.Experimenal result shows its performance is much better than the conventional scheme,near to the schemes based on user's characters.Besides,it needs not to change the current location update procedure and paging procedure,and has not any signaling cost adding.It has a great prospect of engineering application.
