Abstract  Abstract

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.
