为解决CDMA2000 1X[1]分组网络节点移动问题,本文利用移动IP[2]技术代替原有的简单IP,使节点可以以一个永久的IP地址连接网络,从而保证链路切换时的正常通信。通过OPNET工具设计了移动IP在CDMA2000 1X分组网中的仿真模型,并在此基础上对其功能和性能进行了分析,证实了方案的可行性。
In order to solve the problem of node mobility in CDMA2000 1X [1] packet network, this paper uses mobile IP [2] technology instead of simple IP so that nodes can connect to the network with a permanent IP address so as to ensure normal communication during link switching. The simulation model of Mobile IP in CDMA2000 1X packet network is designed by OPNET tool, and its function and performance are analyzed based on this, which proves the feasibility of the scheme.
