摘要： The embodiment of the present invention relates to a method and a system for switching station in centralized wireless local area network (WLAN) when the WLAN privacy infrastructure (WPI) is performed by an access controller (AC). The method includes: step 1: the station re-associates with the AC through the destination wireless terminal point (WTP); step 2: the AC informs the associated WTP to delete the station; step 3: the AC informs the destination WTP to join the station. The invention implements the operation of joining station and deleting station between the AC and the WTP based on the control and provisioning of wireless access points protocol (CAPWAP) control message during the process of switching station. Therefore, the invention can quickly and safely implement the station switching among the WTPs under the same AC.
