Embodiment Construction

[0034] see figure 1 , 2 , according to a preferred embodiment of the present invention, its specific method is as follows:

[0035] 1) The STA re-associates with the AC through the destination WTP;

[0036] 1.1) The STA passively listens to the beacon frame of the destination WTP to obtain the relevant parameters of the destination WTP including the WAPI information element. The WAPI information element includes the WAI authentication and key management suite, cipher suite, etc. supported by the destination WTP; The WTP sends a probe request frame. After receiving the probe request frame from the STA, the destination WTP sends a probe response frame to the STA. After receiving the probe response frame, the STA obtains the relevant parameters of the destination WTP including the WAPI information element. The WAPI information element includes the destination WTP Supported WAI authentication and key management suites, cipher suites, etc.;

[0037] 1.2) In the local MAC mode, t...

Abstract

The invention relates to an STA roam switching method when WPI is finished by AC in a convergence type WLAN and a system thereof. The method comprises the steps as follows: 1) site STA is re-relevantly connected with an access controller (AC) by a target wireless terminal point (WTP); 2) the AC notifies the relevant WTP to delete the site STA; and 3) the AC notifies the WTP to add the site STA. Inthe switching process of STA, The invention can realize STA addition and STA deletion operations between AC and WTP based on CAPWAP control messages, can safely and fast realize site STA switching among WTPs under the same AC.

Description

technical field [0001] The invention relates to a STA switching method and a system thereof when an AC completes WPI in a convergent WLAN. Background technique [0002] At present, the STA (Station) switching methods in WLAN (Wireless Local Area Network) based on the WAPI (WLAN Authentication and Privacy Infrastructure) protocol are all proposed under the autonomous WLAN architecture, which cannot be directly applied to the WAPI-based convergent WLAN system. architecture. In the converged WLAN architecture, access control devices such as the access controller AC (Access Controller), wireless switches or wireless routers centrally manage WLAN authentication and policy enforcement functions, and these devices can also provide centralized bridging, forwarding, encryption and decryption functions such as user data. Contents of the invention [0003] In order to solve the defect that the current WAPI-based WLAN station STA switching method in the background technology is only...
