摘要
根据地铁环境下无线通信的特殊性,对无线接入进行了重新设计。研究并继承了传统移动IP的思想,并对其进行了一定的修改,将移动代理大部分职能与无线接入点进行分离,实现了移动节点与无线接入点之间快速正确切换的功能,在不同的网段中移动时实现了漫游功能,并且实现了有、无线网络的连接畅通。最后描述了系统的测试结果以及存在的不足。
This paper designs a new access point to satisfy the need of wireless communication in the subway environment. Based on the conventional mobile IP theory, some modification is made to separate out most functions of mobile agent from wireless access point so that rapid and accurate transfer between MN （mobile node） and wireless access point, the roaming function of MN in different LANs, and good communication between LAN and WLAN are realized. The testing result is described and weaknesses are analyzed.
