Patent ID: 8463976

Claim:
A dual modem device comprising: a first processor to communicate with a first wireless network; and a second processor to communicate with a second wireless network, wherein the first processor includes: a USB module to transceive a signal with a computer side using a universal serial bus (USB) interface, a first packet control block to determine a type of the signal received via the USB module, based on whether the signal is a data signal or a control signal, to determine a network currently connected to the dual modem device and to determine a communication path based on the determined type of the signal and the determined currently connected network, and a first function block to process a signal associated with the first wireless network, wherein the second processor includes: a first control block to process a control signal for the first processor, a second control block to process a control signal for the second processor, and a second function block to process a signal associated with the second wireless network, wherein when the currently connected network is the first wireless network, the first packet control block determines: a data signal communication path as connecting through the first packet control block and the first function block, and a control signal communication path as connecting through in an order of the first packet control block, the first control block and the first function block, and wherein when the currently connected network is the second wireless network, the first packet control block determines: both a data and a control signal communication path as connecting through in an order of the first packet control block, the second control block and the second function block.
