| 摘 要： | 统一的认证和计费是WLAN和蜂窝系统融合的基础,EAP-SIM协议框架不仅为WLAN提供了一种更安全有效的认证方式,也为蜂窝系统引入了一种具有高数据传输速率的无线宽带接入方法;通过将AC置于网络控制的核心位置,利用集中式DHCP、实时流量统计、用户带宽调节、动态路由控制等方式,并采用创新的旁路式设计方法,从而灵活地解决了传统上集中控制优势和转发能力瓶颈的矛盾,为移动运行商的商业化部署带来了极大的便利.文章所给出的以AC为核心的WLAN网络的技术设计及具体实现已经投入运营商现网,并在全国范围内进行了大规模的部署且已开始了商业化运营;网络运行稳定、高效.

| Abstract: | Integrated authentication and accounting is the basis for the merge of WLAN/GSM,and GSM-SIM card is actually the bridge.Presented by IETF and 3GPP,EAP-SIM authentication framework is not only an authentication method,but also a bridge which combining WLAN and the celluar networks.The EAP-SIM authentication technique is studied thoroughly,aiming at mixing the security advantages of WLAN and GSM/GPRS network and trying to provide a practical, operational implementation with AC as the core component of the control plan. |
