A cellular radiotelephone autonomous registration method. The radiotelephone attempts registration when a clock count transmitted by the system equals or exceeds the radiotelephone's threshold count (201). The radiotelephone then scans (202) available channels for proper signal strength and attempts to seize that channel (203). If the channel seizure fails, the threshold count is updated with the clock count plus a random integer (207) and the next channel seizure attempt is made when the next master clock value equals or exceeds this value. This method increases the length of time between failed channel seizure attempts, thereby decreasing the load on the radiotelephone's power source. |
