<p>The present invention discloses an, optimized interaction method of a user terminal selecting an optimal access mobile communication operation network in a Wireless Local Area Network (WLAN), comprising: after a wireless connection between the WLAN user terminal and a WLAN access network is established, the network or the WLAN user terminal initiating an access authentication procedure, and the WLAN access network sending a user identity request message to the WLAN user terminal; after receiving the user identity request message, the WLAN user terminal determining the network selection information to be currently carried according to a detecting result of whether the WLAN access network is changed or according to the user selection information, and returning a message containing the determined network selection information to the WLAN access network; the network judging whether the network selection information in the received message indicates one of the mobile communication operation networks to which the WLAN is currently connected; if so, sending an access authentication request from the WLAN user terminal to the mobile communication operation network indicated by the network selection information, otherwise, the network sending a notification signaling to the WLAN user terminal, the WLAN user terminal completing subsequent operations according to contents in the notification signaling. With the present invention, when being accessed to a WLAN that is connected to multiple mobile communication operation networks, the user terminal is capable of selecting an optimal mobile communication operation network to access according to the requirements.</p> |
