Method of speeding call flow
First Claim
1. A method of communicating between a vehicle and a central facility, comprising the steps of:
- (a) initiating at a vehicle a request for turn-by-turn directions;
(b) establishing a packet-switched call between the vehicle and a central facility using a mobile dialed number (MDN) and a hotline number, provided by a wireless carrier system, that permits a plurality of simultaneous calls associated with the MDN;
(c) offering a vehicle occupant a service option that uses a circuit-switched call;
(d) 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; and
(e) receiving determined route information at the vehicle from the central facility via the packet-switched call.

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.

9. A method of communicating between a vehicle and a central facility, comprising the steps of:
-
(a) receiving at a central facility vehicle identity information and a request for turn-by-turn directions sent from the vehicle via a wireless carrier system; (b) establishing a packet-switched call between the vehicle and the central facility using a mobile dialed number (MDN) and a hotline number, provided by a wireless carrier system, that permits a plurality of simultaneous calls associated with the MDN; (c) receiving a request from the vehicle for a service option that uses a circuit-switched call; (d) directing the wireless carrier system from the central facility to establish the circuit-switched call using the MDN and to maintain the packet-switched call in a dormant state; and (e) sending a determined turn-by-turn route from the central facility to the vehicle via the packet-switched call. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of communicating between a vehicle and a central facility, comprising the steps of:
-
(a) receiving a request for turn-by-turn directions from a vehicle that also includes vehicle identifying information and mobile dialed number (MDN); (b) establishing a packet-switched call between the central facility and the vehicle via a hotline number provided by a wireless carrier system that permits a plurality of simultaneous calls associated with the MDN; (c) offering a vehicle occupant in the vehicle a service option that uses a circuit-switched call; (d) if the vehicle occupant selects the service option, then directing the wireless carrier system to establish the circuit-switched call while maintaining the packet-switched call in a dormant state, wherein both the packet-switched call and the circuit-switched call are simultaneously connected through the wireless carrier system using the MDN; (e) receiving voice communication for turn-by-turn directions at the central facility from the vehicle occupant via the circuit-switched call; (f) ending the circuit-switched call; and (g) sending a response to the request for turn-by-turn directions via the re-activated packet-switched call. - View Dependent Claims (18)
