摘要： 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% 。

Abstract: 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.
