Abstract  Abstract

An interworking method and interworking system between a cellular network (110) and a wireless local area network (WLAN; 130a, 130b) are disclosed. At least one cellular network (110), at least one WLAN (130a, 130b) and an IP network (140) are deployed. Initially, the wireless transceiver unit (WTRU; 102) establishes a connection with the WLAN (130a) and a tunnel is established between the access point (AP; 132a) and the packet data gateway (PDG; 129). The PDG (129) further establishes a tunnel with the IP network (140). The WTRU (102) then invokes a service delivered via the WLAN (130a). If the signal quality from the AP (132a) falls below a predetermined threshold, a handover from the WLAN (130a) to the cellular network (110) is performed.
