Abstract  Abstract

A method and system for interworking between cellular networks and wireless local area networks (WLANs) is disclosed. At least one cellular network, at least one WLAN and one IP network are deployed. A wireless transmission / reception unit (WTRU) first establishes a connection with a WLAN and a tunnel between an access point (AP) and a packet data gateway (PDG). The PDG also establishes a tunnel to an IP network. The WTRU then invokes a service that is delivered through the WLAN. Upon degradation of the signal quality of the AP below a predetermined threshold, a switching from the WLAN to the cellular network is carried out. A new connection to the cellular network can be established either before or after the current connection to the WLAN is cut off or the two connections can be maintained simultaneously.
