1. A mobile communications device, comprising:
- a first processor of the mobile communications device configured to control an operation of a peripheral device;
at least one second processor of the mobile communications device configured to transport data between the mobile communications device and at least one wireless network that is external to the mobile communications device, the at least one second processor being configured to maintain a network connection between the mobile communications device and the at least one wireless network based upon a periodically received command to maintain the network connection, the at least one second processor comprising a plurality of modems, each modem configured to transport data between the mobile communications device and a different wireless network; and
a third processor of the mobile communications device connected between the first processor and the at least one second processor, the third processor being configured to direct the at least one second processor to execute a network operation to maintain the network connection independently of the first processor without awaking the first processor from a sleep mode, the network operation including the at least one second processor periodically sending a message to the at least one wireless network that is external to the mobile communications device to maintain the network connection between the mobile communications device and the at least one wireless network, the third processor being configured to direct the at least one second processor to maintain the network connection by periodically transmitting the command to maintain the network connection from the third processor to the at least one second processor at a predetermined time interval.

18. A method for maintaining a network connection between a mobile communications device and a wireless network, comprising:
-
establishing a network connection between the mobile communications device and the wireless network, wherein the wireless network is external to the mobile communications device; allowing a first application processor of the mobile communications device, which controls operations of at least one peripheral device, to enter a low power mode when the mobile communications device is in an idle state; and maintaining the network connection with the external wireless network using a third network processor of the mobile communications device to control a second communication processor of the mobile communications device for sending periodic messages to the external wireless network to maintain the network connection between the mobile communications device and the external wireless network without awakening the first application processor of the mobile communications device from the low power mode, wherein the third network processor is connected between the first application processor and the second communication processor, wherein the second communication processor comprises a plurality of modems, each modem configured to transport data between the mobile communications device and a different external wireless network, wherein maintaining the network connection includes; periodically transmitting a command from the third network processor of the mobile communications device to the second communication processor of the mobile communications device at a predetermined time interval that commands the second communication processor of the mobile communications device to send the periodic messages to the external wireless network.
