A method and system are disclosed for a transmitter to maintain priority on a communication channel in a multiple wireless communication system environment. An exemplary method for maintaining priority includes transmitting a priority signal to maintain priority for the transmitter on the communication channel. The priority signal may be pseudo-random noise (PRN) signals. In one embodiment, the PRN signals are transmitted in response to activity sensed on the communication channel, one cause of which may be a contending transmitter transmitting on the communication channel. In this embodiment the step of transmitting is for a predetermined duration and causes the contending transmitter to stop transmitting on the communication channel. In an alternate embodiment, the transmission of the PRN signals is periodic and occurs sufficiently often to cause the contending transmitter to abstain from ever transmitting on the communication channel.
A method for a transmitter of a first cellular system that handles telephone calls on a communication channel to maintain priority on the communication channel over a contending transmitter of a second cellular system, comprising:
A radio of a first cellular system that handles telephone calls on a communication channel, the radio comprising:
A system for enabling a first cellular system that handles telephone calls on a communication channel to maintain priority on the communication channel over a second cellular system, comprising:
