Abstract

The present invention provides an access authentication method, which can enable AC to create a temporary entry of the wireless client when receiving the access request message sent by the wireless client that accesses for the first time, and the temporary entry includes the access request message in the access request message. Carry the first IP address of the wireless client and the MAC address of the wireless client, then obtain the user information of the wireless client from the Portal server according to the MAC address, and obtain the access of the wireless client locally according to the first IP address and MAC address Information, send the user information and access information to the authentication server for authentication, after the authentication is passed, the wireless client can be allowed to access and process the access request message. Therefore, the present invention can quickly access the network without reapplying for an IP address when the client moves across ACs in a large-scale WLAN network, thereby improving the access experience of the wireless client.

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 popularization of smart mobile wireless clients, users have higher and higher requirements for mobile access experience. At present, it can support the mobile switching of the authenticated wireless client of WLAN (Wireless LAN) network within an ESS (Extended Service Set). The already applied IP address is not released before and after switching, and the wireless client can use the original There is an IP address for data communication, which reduces the traffic interruption time caused by wireless link switching. [0003] However, in a large-scale WLAN network, the demand for wireless clients to switch between wireless services provided by different AC (Access Control) devices has become increasingly obvious. Because the wireless client switches quickly in the ESS without re-applying fo...
