Abstract
Embodiments of the present invention include a method and system for operating a dual mode terminal that includes a wireless local area network interface and a cellular radio interface. According to an embodiment, the dual mode terminal camps on the cellular radio interface when idle. When a Page Request message is received over the cellular radio interface, the terminal determines whether wireless local area network coverage is possible from an access point providing wireless local area network cellular communication. If so, the terminal processes the incoming communication request over the wireless local area network towards another party, wherein then the communication is ended, the terminal goes back to camp on the cellular channel.
