Abstract  Abstract

The present invention discloses a method and system for interconnecting a cellular network and a wireless local area network (WLAN). It deploys at least one cellular network, at least one wireless local area network, and an Internet Protocol (IP) network. First, a WTRU establishes a connection with a wireless local area network and establishes a path between an access point (AP) and a packetized data gateway (PDG). The packet data gateway further establishes a channel with the Internet communication protocol network. The WTRU then triggers the service delivered via the wireless area network. The handover from the wireless local area network to the cellular network is implemented when the quality of the signal from the access point is degraded below a predetermined threshold. A new connection to the cellular network can be established before or after the current connection to the wireless local area network is interrupted, or both connections can be maintained at the same time.
