METHOD FOR PROCESSING NETWORK SELECTION INFORMATION OF USER TERMINAL IN WIRELESS LOCAL AREA NETWORK

摘要

The present invention discloses a method for processing network selection information of user terminal in wireless local area network (WLAN). When a WLAN user terminal accessing a wireless communications network via a WLAN access network (WLAN AN), the WLAN user terminal sending to the WLAN AN an authentication signaling carrying network selection information. The WLAN AN forwarding the authentication signaling to an Authentication Authorization Accounting (AAA) proxy in the visited network; having received the authentication signaling, the AAA proxy in the visited network removing the information of the visited network in network selection information from the authentication signaling and sending a modified authentication signaling to the home network of the WLAN user terminal. This invention enables user terminal to select an appropriate wireless communication network to get accessed when it tries to access via a WLAN connecting with a plurality of wireless communication networks.
