Communication System Using Cellular System As An Alternate To A Vehicle To Vehicle Radio
A method and system includes a first vehicle radio generating a first communication signal for a second vehicle radio and communicating the first communication signal through the first radio system of a first vehicle. The first vehicle radio communicating the first signal though a cellular system to the second vehicle radio when a response signal is not received from the second vehicle radio.
1 . A method comprising:
generating a first communication signal at a first vehicle radio for a second vehicle radio;
communicating the first communication signal through a the first radio of a first vehicle; and
when a response signal is not received from the second vehicle radio, communicating the first communication signal though a cellular system to the second vehicle radio.
2 . The method as recited in claim 1 wherein the first communication signal comprises a first position data and first vehicle identifier.
3 . The method as recited in claim 2 further comprising communicating the first vehicle identifier and the first position data to the second vehicle radio in both a fast pipe and a slow pipe.
4 . The method as recited in claim 1 wherein the response signal comprises a first position signal and first vehicle identifier.
5 . The method as recited in claim 1 wherein the response signal comprises an acknowledgement signal.
6 . The method as recited in claim 1 further comprising when a second response signal from the second vehicle radio is not received at the first vehicle radio, communicating the first communication signal to a satellite.
7 . The method as recited in claim 1 further comprising communicating the response signal to the second vehicle radio during both a fast pipe and a slow pipe.
8 . A system comprising:
a first vehicle radio generating a first communication signal for a second vehicle radio and communicating the first communication signal through the first vehicle radio of the first vehicle; and
said first vehicle radio communicating the first communication signal though a cellular system to the second vehicle radio when a response signal is not received from the second vehicle radio.
9 . The system as recited in claim 8 wherein the first communication signal comprises a first position data and first vehicle identifier.
10 . The system as recited in claim 9 further comprising communicating the first vehicle identifier and the first position data to the second vehicle radio in both a fast pipe and a slow pipe.
11 . The system as recited in claim 8 wherein the response signal comprises a first position signal and first vehicle identifier.
12 . The system as recited in claim 8 wherein the response signal comprises an acknowledgement signal.
13 . The system as recited in claim 8 further comprising when a second response signal form the second vehicle radio is not received at the first vehicle radio, communicating the first communication signal to a satellite.
14 . The system as recited in claim 8 further comprising communicating the response signal to the second vehicle radio during both a fast pipe and a slow pipe.
