Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and a system for interworking between cellular networks and WLANs.

SOLUTION: At least one cellular network 110 at least one WLAN 130a 130b and an IP network 140 are deployed. A WTRU 102 first establishes a connection to a WLAN 130a and a tunnel between an AP 132a and a PDG 129 is established. The PDG 129 further establishes a tunnel to the IP network 140. The WTRU 102 then invokes a service which is delivered through the WLAN 130a. As signal quality from the AP 132a degrades below a predetermined threshold a handover from the WLAN 130a to the cellular network 110 is performed.
