Abstract:
1. A radio terminal for an ad-hoc, peer-to-peer radio system comprising a series of radio terminals, each said radio terminal comprising transceiver means for transmitting and receiving signals from other like terminals of said series of terminals, computer means, memory means for storing program software means therein, and software means, said radio system based on time-dependent messaging having multiple parallel data channels and a control channel, the improvement comprising: said software means comprising means for generating communications-information for transmission based on time-division messaging; said communications-information comprising a series of time flames (TM) each divided into a series of time slots (TS); said communications-information comprising at least one time slot in which control-channel (CC) messaging information is transmitted, and other time slots in which is transmitted channel data (CD) messaging information; said software means further comprising sending means for sending out message-signaling toward other said radio terminals for finding and registering with at least one other of said other radio terminals; said sending means comprising transmitting status messaging in said time slots over said control channel; said software means also comprising listening means for listening to a response to said status messaging from at least another said radio terminal on said control channel; said software means further comprising random means for randomly selecting at least another said time slot of at least one subsequent said time frame for said sending means to transmit said status messaging when said listening means receives no response; said software means comprising power-incrementing means for increasing the power of transmission of said status messaging over a subsequent, selected, respective said time slot on the control channel as compared with a previous said time slot in which said status messaging was transmitted on the control channel.
