Abstract

Jamming is detected as occurring to communications associated with at least one electronic device disposed at a vehicle. Responsive to detecting the jamming, an indication is transmitted from the vehicle to a base station informing the base station that jamming is occurring. Communications are subsequently conducted between the base station and the vehicle on at least one predetermined and prearranged communication channel.

Claims

1. A method of maintaining communications with a vehicle in the presence of jamming, the method comprising:

detecting that jamming of communications associated with at least one electronic device disposed at a vehicle is occuring;

responsive to detecting the jamming, transmitting an indication from the vehicle to a base station informing the base station that jamming is occurring;

subsequently conducting communications between a stolen vehicle tracking (SVT) server and the vehicle on at least one predetermined and prearranged communication channel.

2. The method of claim 1 further comprising tracking the location of the vehicle.

3. The method of claim 2 wherein tracking the location of the vehicle comprises tracking the location of the vehicle using at least one of:

triangulation approaches and GPS receiver location information.

4. The method of claim 1 wherein the at least one predetermined and prearranged communication channel is determined at least in part based upon the geographical area where the vehicle is operating.

5. The method of claim 1 wherein the at least one predetermined and prearranged communication channel comprises at least one of:

a frequency modulation (FM) frequency direct sequence spreading and code division multiple access (CDMA) modulation.

6. The method of claim 1 wherein the communications are accomplished using an existing transmitter that transmits normally over an existing communication channel, the transmitter being re-configured to transmit over the at least one predetermined and prearranged communication channel and not the existing communication channel.

7. The method of claim 6 wherein the existing communication channel is selected from the group consisting of:

a Global System for Mobile communications (GSM) channel, an out-of-band GSM channel, a code division multiple access (CDMA) channel and an out-of-band CDMA channel.

8. The method of claim 1 wherein the indication comprises information selected from the group consisting of:

a last known location of the vehicle, a speed of the vehicle, an acceleration of the vehicle.

9. The method of claim 1 wherein the communications are conducted over an alternative base station.

11. The apparatus of claim 9 wherein the at least one predetermined and prearranged communication channel is determined at least in part based upon the geographical area where the vehicle is operating.

10. An electronic apparatus disposed in a vehicle, comprising:

an interface with an input and an output;

a controller coupled to the interface, the controller being configured to receive a signal at the input of the interface, the signal indicating that jamming of communications at the vehicle is occurring, the controller further configured to responsive to the signal, transmit an indication at the output of the interface to a base station informing the base station that jamming is occurring, the controller configured to subsequently conduct communications with a stolen vehicle tracking (SVT) server at the output of the interface on at least one predetermined and prearranged communication channel.

12. The apparatus of claim 10 wherein the at least one predetermined and prearranged communication channel comprises at least one of:

a frequency modulation (FM) frequency, direct sequence spreading and code division multiple access (CDMA) modulation.

13. The apparatus of claim 10 wherein the interface comprises an existing transmitter and the communications are accomplished using the existing transmitter that transmits normally over an existing communication channel, the transmitter being reconfigured by the controller to transmit over the at least one predetermined and prearranged communication channel and not the existing communication channel.

14. The apparatus of claim 13 wherein the existing communication channel comprises a Global System for Mobile communications (GSM) channel.

15. The apparatus of claim 10 wherein the indication comprises information selected from the group consisting of:

a last known location of the vehicle, a speed of the vehicle, an acceleration of the vehicle.

16. The apparatus of claim 10 wherein the electronic apparatus is disposed at a location selected from the group consisting of:

within a vehicle, within a vehicle communication systems, within a stolen vehicle tracking device, within an integrated vehicular mobile communications device, and within a vehicle telematics unit.

17. Memory comprising instructions executable by one or more processors to:

detect that jamming of communications associated with at least one electronic device disposed at a vehicle is occurring;

responsive to detecting the jamming, transmit an indication from the vehicle to a base station informing the base station that jamming is occurring;

subsequently conduct communications between a stolen vehicle tracking (SVT) server and the vehicle on at least one predetermined and prearranged communication channel.

18. The memory of claim 17 further comprising further instructions executable by one or more processors to track the location of the vehicle using at least one of:

triangulation approaches, and GPS receiver location information.

19. The memory of claim 17 wherein the at least one predetermined and prearranged communication channel comprises at least one of:

a frequency modulation (FM) frequency, direct sequence spreading and code division multiple access (CDMA) modulation.

20. The memory of claim 17 wherein the communications are accomplished using an existing transmitter that transmits normally over an existing communication channel, the transmitter being re-configured to transmit over the at least one predetermined and prearranged communication channel and not the existing communication channel.
