在移动通信系统中,蜂窝的范围从宏蜂窝进一步缩小到微蜂窝,而传统的移动IP协议仅适用于宏蜂窝系统,若在微蜂窝系统中仍采用移动IP协议,将会导致网络运行效率的下降。蜂窝IP协议和HAWAII协议是两种解决移动IP在处理IP移动性上的低效问题的方案。文章对蜂窝IP协议和HAWAII协议进行了介绍,并对两种协议进行了比较。
In the mobile communication system, the range of the cellular is further reduced from the macro cell to the micro cell. However, the traditional Mobile IP protocol is only applicable to the macro cell system. If the mobile IP protocol is still used in the micro cell system, the network operation efficiency decline. The cellular IP protocol and the HAWAII protocol are two solutions to the inefficiencies of mobile IP in handling IP mobility. The article introduces the cellular IP protocol and HAWAII protocol, and compares the two protocols.
