基于双BRAS的WLAN双SSID切换时延解决方案

The Solution Of the Handoff Delay of the Two SSID in WLAN Base on Two BRAS

同一WLAN热点下双SSID间切换存在等待一个DHCP租期的问题,通过将同一热点下不同SSID上联不同的宽带远程接入服务器(BRAS),实现有效降低双SSID间切换时延。通过现网实验证明,该解决方案能够达到预期效果,提升用户对WLAN网络的体验感知。该方案已在在重庆电信公众WLAN网络中进行了推广使用。

There is a problem that we must wait a DHCP terra, if we switch one SSID to another in the same WLAN. The solution that the different SSID links the different BRAS can reduce the handoff delay. The experimental proof the solution can achieve the expected effect. And it can advance the users＇ experience. The solution has been extended in the public WLAN of the Chongqing telecom.
