Abstract
An automatic cell transfer is made, when a mobile detects certain threshold exit bit or symbol error rate in a message transmitted from the base station with which it is communicating, by the mobile then sampling sequentially transmitted messages from adjacent base stations (on the same or different frequencies) and monitoring their bit or symbol error rates until a base station is found having a bit or symbol error rate less than a preselected minimum entry threshold bit or symbol error rate which in turn is less than the exit bit or symbol error rate and transferring communication from the mobile to the base station so selected. In one arrangement, each base station repeatedly and intermittently transmits a known quality assessment message and the mobile continually reviews the received message for its error rate.
