Abstract

The invention provides a method, a computer usable medium including a program, and a system for operating a vehicle telematics device. The method includes providing a wireless communications gateway between an input device and the vehicle telematics device. Data is physically entered into the input device. The physically entered data is communicated between the input device and the vehicle telematics device via the wireless communications gateway. A service request is placed to a call center based on the physically entered data.

Claims

1. A method of operating a vehicle telematics device, the method comprising:

providing a wireless communications gateway between an input device and the vehicle telematics device;

physically entering data into the input device via one or more keys on the input device, wherein individual keys or key combinations of the input device are mapped to at least one in-vehicle data message;

generating from the entered data a mapped in-vehicle data message for placing a call;

communicating the mapped in-vehicle data message from the input device to the vehicle telematics device via the wireless communications gateway; and

placing the call from the vehicle telematics device based on the mapped in-vehicle data message.

2. The method of claim 1 wherein the wireless communications gateway comprises a communications protocol.

3. The method of claim 2 wherein the communication protocol is selected from a group consisting of:

802.11 series, Bluetooth, Wi-Fi, direct-sequence spread spectrum, frequency-hopping spread spectrum, and shared wireless access protocol.

4. The method of claim 1 wherein the input device is selected from a group consisting of:

a personal digital device, a wireless device including a keypad, a cellular telephone, and a handheld computing device.

5. The method of claim 1 wherein communicating the physically entered data comprises encoding communicated data.

6. The method of claim 1 further comprising detecting the input device.

7. The method of claim 6 wherein detecting the input device comprises transmitting at least one of identification information and a handshake protocol between the input device and the vehicle telematics device.

8. A method of operating a vehicle telematics device using a portable wireless device, the method comprising the steps of:

physically entering data into a portable wireless device;

creating a data message using the data, the data message being capable of commanding the vehicle telematics device to place a call using dialing digits contained in the data message;

establishing a wireless data connection between the portable wireless device and the vehicle telematics device;

sending the data message from the portable wireless device to the vehicle telematics device via the wireless data connection and, in response thereto;

placing a call over a wireless carrier system from the vehicle telematics unit using the dialing digits received in the data message.

9. The method of claim 8 wherein the call is selected from a group consisting of:

data transfers and service requests.

10. The method of claim 8 wherein the step of sending the data message further comprises sending dialing digits to the telematics device for initiating voice calls via a network interface.

11. The method of claim 8 wherein the data message is DTMF data for accessing remote telephony systems.

12. The method of claim 11 wherein the data message is sent through an audio channel that maps DTMF signals.

13. The method of claim 8 wherein the wireless data connection is selected from a group consisting of:

802.11 series, Bluetooth, Wi-Fi, direct-sequence spread spectrum, frequency-hopping spread spectrum, and shared wireless access protocol.

14. The method of claim 8 wherein the portable wireless device performs an authentication process where identification information is exchanged between the portable wireless device and the vehicle telematics device.

15. The method of claim 8 wherein the wireless data connection uses a wired-equivalent privacy data encryption protocol to control access to the vehicle telematics device.

16. A method of operating a vehicle telematics device using a portable wireless device, the method comprising the steps of:

establishing a wireless data connection between a portable wireless device and a vehicle telematics device;

placing a call over a wireless carrier system from the vehicle telematics device;

communicating with a remote telephony system via the call; and

accessing the remote telephony system using keys on the portable wireless device, wherein the accessing step further comprises the following steps;

generating a data message using data physically inputted into the portable wireless device via keys on the portable wireless device;

sending the data message to the vehicle telematics device over the wireless data connection; and

sending DTMF data from the vehicle telematics device to the remote telephony system in accordance with the data message received from the portable wireless device.
