Abstract

Extending the activation and tracking capability of stolen vehicle recovery dedicated radio-frequency networks by the supplementary use of widely geographically provided cellular telephone-frequency band networks.

Claims (26)

  1. What is claimed is:

    I. A method of utilizing the relatively wide-geographically spread cellular radio networks to supplement more limited stolen vehicle recovery radio network sites in activation of radio tracking and recovery of such a vehicle, that comprises, equipping the vehicle with both a transponder for replying with a unique reply code transmission to a query from the recovery networks and a transceiver for, replying with unique identification transmission to a query from the cellular network; upon confirming vehicle theft at a control center, instructing both the recovery network and the cellular network to send their respective queries to the respective transponder and transceiver of the vehicle;
    receiving from the vehicle transceiver, said unique identification transmission at a site of the cellular network and sending from such site an identifying number thereof to the control center for providing over the wide geography of the cellular network, rough location guidance information to a recovery vehicle; and receiving from the vehicle transponder at such recovery vehicle its reply code transmission to enable fine tracking by the recovery vehicle of the stolen vehicle.
  2. 2. The method of claim 1 wherein the recovery radio network and vehicle transponder operate on a dedicated frequency, and the cellular network and vehicle transceiver operate in a predetermined band of assigned cellular telephone frequencies.
  3. 3. The method of claim 2 wherein said dedicated frequency is a VHF frequency and the cellular telephone frequencies are in the UHF band.
  4. 4. The method of claim 3 wherein the recovery radio network is of the LOJACK
    type and the cellular radio network is of the GSM type.
  5. 5. The method of claim 1 wherein an early warning theft uplift message is sent via either or both of the recovery radio network and the.cellular network to the control center.
  6. 6. The method of claim 5 wherein vehicle movement sensing triggers such an uplift message.
  7. 7. The method of claim 5 wherein the vehicle is further equipped with a GPS
    receiver and the received latitude-longitude coordinates of the stolen vehicle is also sent to the control center.
  8. 8. The method of claim 7 wherein the received GPS coordinates are sent via said uplift messages.
  9. 9. The method of claim 1 wherein the fixed site transmitters of the recovery network sites are supplemented by vehicular-carried portable transmitters as by the recovery vehicle.
  10. 10. The method of claim 9 wherein the recovery vehicle is one or both of a direction-finding patrol car or an airborne vehicle such as a helicopter.
  11. 11. The method of claim 7 wherein emergency or accident sensing at the vehicle triggers such an uplift message.
  12. 12. The method of claim I wherein a deactivation signal is sent by the cellular network when appropriate.
  13. 13. Apparatus for utilizing the relatively wide-geographically spread cellular radio networks to supplement more limited stolen vehicle recovery radio network sites in activation of radio tracking and recovery of such a vehicle, the apparatus having, in combination, a vehicle-equipped transponder for replying with a unique reply code transmission to a query from such a recovery network; a vehicle-equipped transceiver for replying with a unique identification transmission to a query from such a cellular network; a control center, operable upon confirming vehicle theft, for instructing both the recovery network and the cellular network to send their respective queries to the respective transponder and transceiver of the vehicle; means for receiving from the vehicle transceiver said unique identification transmission at a site of the cellular network and sending from such site an identifying number thereof to the control center for providing over the wide geography of the cellular network, rough location guidance information to a recovery vehicle; and means for receiving from the vehicle transponder its reply code transmission to enable fine tracking by the recovery vehicle of the stolen vehicle.
  14. 14. The apparatus of claim 13 wherein the recovery radio network and vehicle transponder operate on a dedicated frequency, and the cellular network and vehicle transceiver operate in the predetermined band of assigned cellular telephone frequencies.
  15. 15. The apparatus of claim 14 wherein said dedicated frequency is a VHF
    frequency and the cellular telephone frequencies are in the UHF band.
  16. 16. The apparatus of claim 15 wherein the recovery radio network is of the LOJACK
    type and the cellular radio network is of the GSM type.
  17. 17. The apparatus of claim 13 wherein means is provided for sending an early warning theft uplift message via either or both of the recovery radio network and the cellular network to the control center.
  18. 18. The apparatus of claim 17 wherein a vehicle movement sensor is provided to trigger such an uplift message.
  19. 19. The apparatus of claim 17 wherein the vehicle is further equipped with a GPS
    receiver, and the received latitude-longitude coordinates of the stolen vehicle are also sent to the control center.
  20. 20, The apparatus of claim 19 wherein the received GPS coordinates are sent via said uplift messages.
  21. 21. The apparatus of claim 13 wherein fixed-site transmitters of the recovery network sites are supplemented by vehicular-carried portable transmitters carried by the recovery vehicle.
  22. 22. The apparatus of claim 21 wherein the recovery vehicle is one or both of a direction finding patrol car or an airborne vehicle such as a helicopter.
  23. 23. The apparatus of claim 19 wherein an emergency or accident sensor is provided at the vehicle to trigger such an uplift message.
  24. 24. The apparatus of claim 13 wherein means is provided for sending a deactivation signal by the cellular network when appropriate.
  25. 25. A method of expanding the activation and tracking capability of a limited number of stolen vehicle recovery dedicated radio-frequency networks activated from a control center upon notification of the theft of the vehicle; that comprises, supplementarily using more numerous widely geographically provided cellular-telephone frequency band networks to respond to the control center to indicate rough location of the stolen vehicle, while the recovery networks provide fine tracking of the vehicle for recovery.
  26. 26. The method of claim 25 wherein the control center activates a stolen-vehicle unique reply code in response to its query through the recovery network, and supplies a cellular site location number to the control center in response to stolen-vehicle identification transmission responsive to a query from the cellular network.
