THE INTERACTIVE METHOD FOR RE-SELECTING THE OPERATION NETWORK BY THE WIRELESS AREA NETWORK WLAN USER TERMINAL

摘要

The present invention discloses an interactive method for a WLAN UE accessing a new operation network, which comprises: when the WLAN UE which has accessed a Visited Mobile Communication Network needs to re-select another Visited Mobile Communication Network to access, the WLAN UE sending authentication information to a Home Network of the WLAN UE through a WLAN Access Network and the Visited Mobile Communication Network newly selected by the WLAN UE; after receiving the authentication information, the Home Network of the WLAN UE authenticate the WLAN UE according to the authentication information via the Visited Mobile Communication Network newly selected by the WLAN UE, and sending an access instruction to the WLAN Access Network through the Visited Mobile Communication Network; and On receiving the access instruction, the WLAN Access Network completing disconnection and/or access between the WLAN UE and the corresponding Visited Mobile Communication Networks. The method enables a WLAN UE to reselect another Visited Mobile Communication Network after accessing a Visited Mobile Communication Network.
