Abstract  Abstract

The invention claims a cellular network (110) and wireless local area network (WLAN) (130a 130b) interconnecting method and system. it is deployed at least one cellular network (110) at least one wireless area network (130a 130b) and an internet communication protocol (IP) network (140). Firstly wireless transmit/receive unit (WTRU) (102) establishes the connection between wireless local area network (130a) and establishing an access point (AP) of the channel (132a) and a packet data gateway (PDG) (129). the packet data gateway (129) further establishes a channel with the IP network (140). Then the wireless transmission/reception unit (102) triggers the service for transmitting via a wireless local area network (130a). when the access point (132a) of the signal quality is degraded to a predetermined critical value and performs the handover to the cellular network (110) by wireless local area network (130a). the interruption and connection of a wireless area network before or after can establish the type of new connection between networks or can continue to maintain two connections.
