Patent ID: 8842615

Claim:
A wireless mobile communication device comprising: a first transceiver configured to wirelessly communicate with a first wireless communication network; a second transceiver which is different from the first transceiver and which is configured to wirelessly communicate with a second wireless communication network which is different from the first wireless communication network; a network load detection system configured to detect load information indicative of an amount of network traffic load on the first wireless communication network; and a second transceiver controller configured to autonomously power on, from a powered down state, the second transceiver to enable use of the second wireless network for data communication, when the load information indicates a heavy network traffic load on the first wireless communication network, wherein; the load information includes one of: a signal from the first wireless communication network directing the first transceiver to change to a slower speed communication channel; a signal from the first wireless communication network directing the first transceiver to increase power of signal transmission; a signal from the first wireless communication network directing the first transceiver to lower the rate of data transmission; information indicative of a signal-to-noise ratio of a signal being received by the first transceiver from the first wireless communication network; and an alternate transceiver activation signal on a channel in the first wireless communication network which is dedicated to the delivery of this signal when the load on the first wireless communication network becomes heavy; and the second transceiver controller is configured to autonomously power on the second transceiver and, if available, use the second network to transmit data in response to receipt of the load information from the first wireless communication network.
