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

摘要

The interactive method for re-selecting the operation network by the wireless area network (WLAN) user terminal, the method comprises the steps as follows: a. When the WLAN user terminal had been connected to a access communication operation network requires the new selection for accessing another access communication operation network, the WLAN access network sent the certification request of said WLAN user terminal to the home network of the said WLAN user terminal through the another access communication operation network that was accessed by the new selection; b. After the home network of said WLAN user terminal received the authentication certification request, it authenticates the authentication certification request from the access communication operation network re-selected by the WLAN user terminal, and sent the operation indication to the WLAN access network via the access communication operation network; c. After the WLAN access network received the operation indication, it completes the cut-off and the access operation between the WLAN user terminal and the corresponding access communication operation network based on the operation indication. The method enables it to re-select another access communication operation network after the user terminal had accessed an access communication operation network.
