US 2007/0190974 A1 · Interacting method for ue fast selecting mobile communication network to access in a wlan interworking network

Abstract

The present invention discloses an interacting method for WLAN UE fast selecting an optimal mobile communication network to access in WLAN, first a WLAN UE judges whether the identity information of the WLAN AN exists in the WLAN identity information stored when mobile connection with the WLAN AN is established, if so, the network selection information corresponding to the identity of the WLAN stored will be sent to the WLAN AN, otherwise, a pre-configured mobile communication network with highest priority is regarded as network selection information to be sent to the WLAN AN; the WLAN AN identifies the mobile communication network to access according to the network selection information carried in Authentication Request, and connects the WLAN UE to the selected network to implement authentication. The method makes the WLAN UE select a mobile communication network to access rapidly when the WLAN UE accesses from a WLAN connected with multiple mobile communication networks.

Dependent claims

An interacting method for a Wireless Local Area Network (WLAN) user equipment (UE) fast selecting a mobile communication network to access in WLAN interworking network, wherein comprising the steps of:

initiating an authentication procedure after the connection between a WLAN UE and a WLAN Access Network (AN) is established;
sending a User Identity Request message to said WLAN UE;
on receiving said User Identity Request message, deciding network selection information to be carried based on the information of the WLAN covering the WLAN UE and/or the WLAN information stored in the WLAN UE, and returning a message carrying said network selection information to said WLAN AN;
deciding whether said network selection information in the received message indicates a mobile communication network to which the WLAN AN is able to route an authentication request message, if yes, the authentication request message of said WLAN UE will be forwarded to the mobile communication network indicated in the network selection information, and otherwise, sending a notification signal to said WLAN UE, and directing said WLAN UE to perform subsequent operations.
