Abstract
A system and method for communicating between a vehicle and a central facility includes initiating at a vehicle a request for turn-by-turn directions; establishing a packet-switched call between the vehicle and a central facility using a wireless carrier system and a mobile dialed number (MDN) associated with the vehicle; receiving determined route information at the vehicle from the central facility via the packet-switched call; offering a vehicle occupant a service option that uses a circuit-switched call; and if the vehicle occupant accepts the service option, directing the wireless carrier system to establish the circuit-switched call using the MDN while maintaining the packet-switched call in a dormant state.
