  • Patent number: 8504123
    Abstract: A mobile communication device enables improved connectivity and power management. The device includes a first wireless network interface configured for connection to a first network and a second wireless network interface configured for connection to a second network. The first interface has an active mode of operation and a sleep mode. The device places the first interface in the sleep mode when not needed for communications. An external system such as a messaging server calls the device when it is unable to access the device through the first interface. The second network, which can be a cellular network, handles the call request and transmits a ringing signal to the second interface of the device. A notification handler, upon receipt of the ringing signal, wakes the first interface, permitting normal communications through the first interface. Power management logic can be more pro-active in placing the first interface into the sleep mode.
