Communication system using vehicle to vehicle radio as an alternate communication means
A system and method of operating the same includes a first radio of a vehicle generating a first communication signal. The first radio attempts to communicate the first communication signal through a first communication system other than a vehicle to vehicle radio. The first radio, when an acknowledgement signal is not received, communicates the first communication signal though the vehicle to vehicle radio to a second vehicle radio.
1. A method comprising:
generating a first communication signal at a first radio of a first vehicle;
attempting to communicate the first communication signal through a first communication system other than a vehicle to vehicle radio; and
when an acknowledgement signal is not received at the first radio, communicating the first communication signal though the vehicle to vehicle radio to a second vehicle radio.
2. The method as recited in claim 1 wherein prior to attempting to communicate the first communication signal and after generating the first communication signal, and attempting to communicate the first communication signal though the first communication system, attempting to communicate the first communication signal through a second communication system.
3. The method as recited in claim 2 wherein the first communication system comprises a terrestrial communication system and the second communication system comprises an extraterrestrial communication system.
4. The method as recited in claim 2 wherein the first communication system comprises a satellite communication system and the second communication system comprises a cellular communication system.
5. The method as recited in claim 2 wherein the first communication system comprises an extraterrestrial communication system and the second communication system comprises a terrestrial communication system.
6. The method as recited in claim 2 wherein the second communication system comprises a satellite communication system.
7. The method as recited in claim 1 wherein the first communication system comprises a cellular communication system.
8. The method as recited in claim 1 wherein communicating the first communication signal comprises communicating the first communication signal from a vehicle-to vehicle radio through a fast pipe and a slow pipe.
9. The method as recited in claim 8 wherein first communication signal comprises a first identifier and a first position signal.
10. A system comprising:
a first radio of a vehicle generating a first communication signal;
said first radio attempting to communicate the first communication signal through a first communication system other than a vehicle to vehicle radio; and
said first radio, when an acknowledgement signal is not received, communicating the first communication signal though the vehicle to vehicle radio to a second vehicle radio.
11. The system as recited in claim 10 wherein the first radio, prior to attempting to communicate the first communication signal, after generating the first communication signal, and prior to attempting to communicate the first communication signal though the first communication system, attempting to communicate the first communication signal through a second communication system.
12. The system as recited in claim 11 wherein the first communication system comprises a terrestrial communication system and the second communication system comprises an extraterrestrial communication system.
13. The system as recited in claim 11 wherein the first communication system comprises a satellite communication system and the second communication system comprises a cellular communication system.
14. The system as recited in claim 11 wherein the first communication system comprises an extraterrestrial communication system and the second communication system comprises a terrestrial communication system.
15. The system as recited in claim 11 wherein the second communication system comprises a satellite communication system.
16. The system as recited in claim 10 wherein the first communication system comprises a cellular communication system.
17. The system as recited in claim 10 wherein communicating the first communication signal comprises communicating the first communication signal from a vehicle-to vehicle radio through a fast pipe and a slow pipe.
18. The system as recited in claim 17 wherein first communication signal comprises a first identifier and a first position signal.
