Abstract
A method and system to provide multiple connections to a device from separate physical networks through the same logical network layer while keeping connections persistent. In order to keep connections persistent and change physical networks, at least one additional connection is needed to seamlessly accomplish the 'hand-off'. If one or more signals from the network host to the device (35) are weak or degraded, then multiple connections can provide redundancy of data being sent from the host to the device reducing the amount of lost data. Multiple connections can be used to increase the amount of data that can be sent to the device at any given time. The system also contains various multiplex servers (49-42) that are assigned to one or more mobile devices, and acting as the device's proxy in order to transfer data back and forth.
