Abstract
Cell phone calls are automatically call forwarded to an in-vehicle telematics system when a driver using the cell phone is in their vehicle. Presence of the driver may be detected, e.g., by detection of a key in the ignition and presumption that the driver is in the vehicle while the key is in the ignition. The in-vehicle telematics unit signals that its driver is present. A phone number lookup is performed, e.g., by a third party database service associating cell phone number and wireless carrier with a telematics phone number of the drivers vehicle. A call forwarding request is then made between the telematics network to the relevant wireless carrier providing service to the driver's cell phone. The correct wireless carrier network is contacted, and a call forward is established to the telematics system of the driver's vehicle. When the driver leaves the vehicle, the call forwarding is terminated.
