摘要
在GPRS中扩展了用户描述信息表以及SGSN和GGSN处理消息的算法,在移动IP中扩展了注册请求消息;在移动IP的基础上实现了GPRS和WLAN的互通,给出了GPRS的Gi接口和WLAN互通的网络体系结构和相应的数据传输协议栈,实现了GPRS和WLAN互通切换时基于AAA认证服务器的移动IP节点认证及注册、通信节点和移动节点间的数据传送。
The paper has extended the information tables of users' description and the algorithms of SGSN and GGSN to process messages in GPRS,has extended registry messages of request in mobile IP,has realized the connection between WLAN and GPRS based on mobile IP;has illustrated the network architecture and the transfer protocol stack;has realized the authentication and registration based on AAA authentication server during clients mobile and data transfer between correspondents and mobile nodes.
