<p>A method is described herein that enables data traffic to be routed seamlessly to a mobile station which is located in a Second Generation/Third Generation (2G/3G) network and a Wireless Local Area Network (WLAN). In one embodiment of the present invention, the mobile station (MS) receives a signal (e.g., System Information (SI) signal) from a base station system (BSS) which informs the MS that it should check for the presence of one or more WLANs. The MS then scans for beacons that are emitted from one or more WLANs. Once, the MS receives a beacon from a WLAN it can access that WLAN. To access the WLAN, the MS could send a signal to the BSS informing the BSS and possibly a gateway GPRS service node (GGSN) that it has received a beacon from the WLAN. Then, the MS can receive a signal from the BSS (or GGSN) which contains information (e.g., password, encrypted key) that enables the MS to access the WLAN. Once, the MS is attached to the WLAN, then the GGSN or another common node can route data to the MS via the WLAN instead of via the BSS.</p> |
