AN OPTIMIZED INTERACTION METHOD OF USER TERMINAL SELECTING ACCESS MOBILE NETWORK IN WIRELESS LOCAL AREA NETWORK

摘要

The present invention disclosed a optimization mutual method of the user terminal select accessing mobile network in WLAN(Wireless Local Area Network ), include steps:The VVLAN user terminal connection with WLAN accessing network in manner of wireless, network or WLAN user terminal beginning the process o f access authentication, WLAN accessing network transmit a request respect of user name message to user terminal. After the user terminal received the request, determine the currently network selection information will to be ta ke depend on the change of the WLAN accesssing network or selection information of the userand return the determined network selection information to VVLAN accessing network. Network determin whether the network selection informatio n is mobile communication network currently connection with VLAN, if istransmi t the request of access authentication to corresponding mobile communication network, if is not, network transmit notification signal to the user termina l, the user terminal carry out the later operation depend on the notification signal.The present invention provide when user terminal access a WALN connection with a plurality of mobile communication work, can optimization access process of selecting optimum mobile communication network depend on require.
