STATION (STA) SWITCHING METHOD AND SYSTEM WHILE COMPLETING WIRELESS LOCAL AREA NETWORK PRIVACY INFRASTRUCTURE (WPI) BY WIRELESS TERMINAL POINT (WTP) IN CONVERGENT WLAN

摘要

A Station (STA) switching method and system while completing Wireless Local Area Network Privacy Infrastructure (WPI) by Wireless Terminal Point (WTP) in the convergent Wireless Local Area Network (WLAN) are provided in the present invention, the method includes the following steps: step 1, Station (STA) performs re-associated connection with Access Controller (AC) through the destination Wireless Terminal Point (WTP); step 2, Station (STA) and Access Controller (AC) update the negotiation session key based on the negotiated base key; step 3, Access Controller (AC) and the destination Wireless Terminal Point (WTP) perform the key synchronization. The present invention can realize the rapid and safe switching for the station which is switched between the wireless terminal points controlled by the same controller in convergent WLAN based on Wireless Local Area Network Authentication and Privacy Infrastructure (WAPI) protocol.
