Problems solved by technology

[0002] With the increasing application of WLAN (Wireless LAN, wireless local area network), the traditional AC (AccessCentral, access controller)-FIT (thin) AP (Access Point, access point) network networking model is in the same network, Multiple areas need to be managed independently. For areas with low network maintenance capabilities, it will undoubtedly increase costs, and it is not conducive to centralized management and maintenance of the entire network; it will be replaced by a new generation of WLAN networks with layered thinking

Abstract

The present invention provides an access authentication method and device, which can enable the local AC to determine the ESS information of the client according to the key identifier if it is determined that the ESS information of the client is the same as the ESS information of the local AC when receiving an associated message from the client forwarded by the AP. Whether the client is a locally authenticated client, if the client is authenticated, the center AC can be notified to modify the client's access AP; if the client is not authenticated, the request center AC continues to judge the client according to the key identifier Whether it has been authenticated, if the central AC determines that the client has been authenticated, it can modify the access AP of the client, and feed back the VLAN information carrying the key and the client to the local AC, so that the client can pass through the existing VLAN information for network access, so as to realize seamless roaming of clients.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an access authentication method and device. Background technique [0002] With the increasing application of WLAN (Wireless LAN, wireless local area network), the traditional AC (AccessCentral, access controller)-FIT (thin) AP (Access Point, access point) network networking model is in the same network, Multiple areas need to be managed independently. For areas with low network maintenance capabilities, it will undoubtedly increase costs, and it is not conducive to centralized management and maintenance of the entire network; instead, a new generation of WLAN networks with layered thinking. In this new generation network, the Central AC (center) is responsible for the management of the entire wireless network, and the Local AC (local) is responsible for AP access and forwarding data traffic, so that centralized management can be realized in the same network. In su...
