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 that is operating in proximity to the vehicle;
transmitting a suppression notice from the primary DSRC system to the secondary DSRC system in response to detecting the secondary DSRC system, where the suppression notice conveys an instruction to the secondary DSRC system to suspend DSRC transmissions of the secondary DSRC system, wherein the suppression notice comprises a time period after which the secondary DSRC system is permitted to resume DSRC transmissions; and
suspending, at the secondary DSRC system in response to the instruction conveyed in the suppression notice, DSRC transmissions of the secondary DSRC system;
wherein suspending, at the secondary DSRC system in response to the instruction conveyed in the suppression notice, DSRC transmissions of the secondary DSRC system, comprises;
causing the secondary DSRC system to enter a suspended operational state in response to the instruction conveyed in the suppression notice, wherein the secondary DSRC system suspends DSRC operations of the secondary DSRC system and does not transmit DSRC transmissions during the suspended operational state to prevent interference with DSRC transmissions of the primary DSRC system.

10. A vehicle-based primary Dedicated Short-Range Communication (DSRC) system comprising:
-
a DSRC transceiver configured to transmit and receive DSRC signals on a DSRC network; and a DSRC controller configured 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, wherein the suppression notice comprises a time period after which the secondary DSRC system is permitted to resume DSRC transmissions, and wherein the secondary DSRC system is configured to suspend DSRC transmissions of the secondary DSRC system in response to the instruction conveyed in the suppression notice; wherein the secondary DSRC system is configured to enter a suspended operational state in response to the instruction conveyed in the suppression notice, wherein the secondary DSRC system suspends DSRC operations of the secondary DSRC system and does not transmit DSRC transmissions during the suspended operational state to prevent interference with DSRC transmissions of the primary DSRC system. - View Dependent Claims (11, 12, 13, 14, 21, 22)

15. A primary Dedicated Short-Range Communication (DSRC) system comprising:
-
a DSRC transceiver configured to transmit and receive DSRC signals on a DSRC network; and a DSRC controller configured to operate the DSRC transceiver to transmit a periodic notification signal, where the periodic notification signal conveys primacy of the primary DSRC system over another secondary DSRC system that is configured to communicate on the DSRC network; wherein the DSRC controller is further configured to detect a secondary DSRC system operating in proximity to the primary DSRC system; 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, and wherein the suppression notice comprises a time period after which the secondary DSRC system is permitted to resume DSRC transmissions. - View Dependent Claims (16, 17, 18)
