Power saving for multi-mode terminal compatible with cellular and WLAN networks

摘要

A mobile communication device (104) is able to communicate with wireless local area network (114, 111) and with a cellular network (108). A communication system (102, 106) is able to route a communication session between the mobile communication device (104) and another communication device (134, 135, 132, 113, 112) either by way of the wireless local area network (114, 111) or the cellular network (108). The communication system (102, 106) is able to trigger the mobile communication device (104) via the cellular network (108) to search for and attempt to connect to the wireless local area network (114, 111). The mobile communication device (104), in response to reception of signaling via the cellular network (108), is able to activate a wireless local area network interface (210) of the mobile communication device (104) and to establish a connection to the wireless local area network (114, 111).
