ABSTRACT:
A system facilitates handover of a wireless transmit and receive unit (WTRU) between a cellular network and a wireless local area network (WLAN). The WLAN communicates with a cellular network. A location of the WTRU is determined. The coverage areas of the WLAN and cellular network are determined. The WTRU is informed of the existence of the WLAN when the WTRU approaches the coverage area of the WLAN. The WTRU is handed over from the cellular network to the WLAN when the WTRU is in the coverage area of the WLAN and vice versa.
