  • Patent number: 8819778
    Abstract: 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.

  • Patent number: 8750521
    Abstract: The invention involves a method and a system for station (STA) switching when a wireless terminal point (WTP) completes wireless local area network (WLAN) privacy infrastructure (WPI) in a convergent WLAN. The method includes steps as follows. The STA implements re-association rebinding process with a target access controller (AC) over a target WTP. A base key is requested by the target AC from an associated AC. An associated WTP is informed to delete the STA by the associated AC, and the target WTP is informed to add the STA by the target AC. A session key is negotiated based on the requested base key by the STA and the target AC, and is synchronized between the target AC and the target WTP. The method enables fast and safe switching of the STA between WTPs under the control of different controllers in the convergent WLAN based on WAPI protocol.
