一种移动IP系统注册管理新方法

在移动IP通信系统中，移动用户在蜂窝边缘移动引发的频繁注册现象是影响通信系统整体性能的一个重要因素。该文主要对移动IP的注册过程进行分析，在移动IP系统原有架构基础上引入子区概念，提出了一种基于移动IP协议的较好的改善频繁注册现象的方法，可以在不改变硬件结构的前提下，较大程度上降低移动用户在蜂窝边缘移动时产生的注册次数，从而提高整体性能，在各项参数取典型值的情况下，实际注册次数下降了20％～30％，总的系统性能可以提高9％～10％。

A New Method for Registration Management of Mobile IP System

In Mobile IP communication system, the vibrating registration, whi ch caused by the mobile-user near the edge of cells, is an important factor whic h decreases the performance of the whole system. This paper analyzes the process of registration in mobile IP and comes up with an improved method using the con ception of sub-region which can preferably solve the vibrating registration base d on the original mobile IP protocol. It can enhance the performance of whole sy stem by obviously decreasing the numbers of registration caused by the mobile-us ers near the edge of cells. Under the circumstance of different typical paramete rs, the total times of registration decrease 20 percent to 30 percent, and the w hole system performance increases 9 percent to 10 percent.
