Abstract
A method, system, and computer-readable code for using a cellular phone as a network gateway in an automotive network. The proposed technique defines a novel way for using the phone's protocol stack and transmission capabilities (together with an adapter) to enable devices on a network in a vehicle to communicate with an external network, while still allowing the phone to work in "stand-alone" mode (i.e. not connected to the vehicle network) where it can communicate to a remote computer as a network client. Further, while the phone is plugged into the automotive network, it retains the ability to operate as a first-class network client. Devices in the vehicle no longer need to include transmission capabilities, thereby reducing their cost. The vehicle owner no longer needs to have a separate wireless subscription for both the phone and the automotive network devices, reducing costs even further.
