A WLAN access point ( 111 ) is synchronized with a Wide Area Network (WAN) ( 105 ) via either a backhaul connection ( 115 ), or via hardware of the WLAN access point ( 111 ) suitable for receiving and decoding a synchronization timing signal from the WAN ( 105 ). The mobile station ( 101 ) transmits a WLAN beacon during the predetermined time window. A WLAN access point ( 111 ) that detects the mobile station ( 101 ) beacon will then communicate with the WAN ( 105 ) via a backhaul connection ( 115 ), to inform the WAN ( 105 ) that a mobile station ( 101 ) has been detected. The WAN ( 105 ) then sends a message to the mobile station ( 101 ) to begin to search for a WLAN access point and handover from the WAN ( 105 ) to the WLAN. |
