Abstract

A method of managing a Dedicated Short-Range Communication (DSRC) network in a vehicle having a primary DSRC system is provided. The method comprises detecting a secondary DSRC system operating in proximity to the vehicle and transmitting a suppression notice in response to detecting the secondary DSRC system, where the suppression notice conveys an instruction to the secondary DSRC system to suspend DSRC transmissions.

Claims

1. A method of managing a Dedicated Short-Range Communication (DSRC) network in a vehicle having a primary DSRC system, the method comprising:

detecting a secondary DSRC system operating in proximity to the vehicle; and

transmitting a suppression notice in response to detecting the secondary DSRC system, where the suppression notice conveys an instruction to the secondary DSRC system to suspend DSRC transmissions.

2. The method of claim 1, wherein transmitting the suppression notice comprises transmitting the suppression notice utilizing a secondary communication channel distinct from the DSRC network.

3. The method of claim 2, wherein utilizing a secondary communication channel comprises transmitting the suppression notice utilizing a radio-frequency communication band.

4. The method of claim 2, wherein utilizing a secondary communication channel comprises transmitting the suppression notice utilizing a low-power, short-range wireless communication band.

5. The method of claim 2, wherein utilizing a secondary communication channel comprises transmitting the suppression notice utilizing a near-field communication band.

6. The method of claim 1, wherein transmitting the suppression notice comprises transmitting the suppression notice on a DSRC communication band of the DSRC communication network.

7. The method of claim 1, further comprising:

receiving a certificate invalidity notice from the secondary DSRC system in response to transmitting the suppression notice; and

operating the primary DSRC system in a secondary role on the DSRC network in response to receiving the certificate invalidity notice.

8. The method of claim 7, further comprising providing feedback to an operator of the vehicle in response to receiving the certificate invalidity notice.

9. The method of claim 1, wherein the secondary DSRC system comprises a cellular phone.

10. A vehicle-based primary Dedicated Short-Range Communication (DSRC) system comprising:

a DSRC transceiver adapted to transmit and receive DSRC signals on a DSRC network; and

a DSRC controller adapted to operate the DSRC transceiver, where the DSRC controller is configured to detect a signal from a secondary DSRC system in proximity to the vehicle and to operate the DSRC transceiver to transmit a suppression notice in response to detecting the signal from the secondary DSRC system, where the suppression notice conveys an instruction to the secondary DSRC system to suspend DSRC transmissions.

11. The system of claim 10, wherein the DSRC controller is further configured to initiate a negotiation session with the secondary DSRC system in response to detecting the signal from the secondary DSRC system.

12. The system of claim 11, wherein the DSRC controller is further configured to transmit the suppression notice after establishment of the negotiation session.

13. The system of claim 11, wherein the negotiation session is conducted utilizing a secondary communication channel distinct from the DSRC network.

14. The system of claim 10, wherein detection of the signal from the secondary DSRC system includes detecting negotiation initiation signals and the DSRC controller is further configured to respond to negotiation initiation signals from the secondary DSRC system.

15. A primary Dedicated Short-Range Communication (DSRC) system comprising:

a DSRC transceiver adapted to transmit and receive DSRC signals on a DSRC network; and

a DSRC controller adapted to operate the DSRC transceiver to transmit a periodic notification signal, where the periodic notification signal conveys primacy of the primary DSRC system to nearby secondary DSRC systems adapted to operate on the DSRC network.

16. The system of claim 15, wherein the DSRC controller is further adapted to detect a secondary DSRC system operating in proximity to the primary DSRC system.

17. The system of claim 16, wherein the DSRC controller is further configured to transmit a suppression notice in response to detecting a secondary DSRC system, where the suppression notice conveys an instruction to the secondary DSRC system to suspend DSRC transmissions.

18. The system of claim 17, wherein the DSRC controller is further adapted to initiate a negotiation session with the secondary DSRC system in response to detecting the secondary DSRC system.

19. The system of claim 17, wherein the DSRC controller is further configured to communicate with the secondary DSRC system utilizing a secondary communication channel distinct from the DSRC network.

20. The system of claim 19, wherein the DSRC controller is configured to communicate with the secondary DSRC system utilizing at least one of a radio-frequency communication band, a low-power, short-range wireless communication band, and a near-field communication band.
