ABSTRACT:
A communications control circuit including a monitor circuit for receiving transmissions of a first and second frequency from a base radio station to other radio stations and measuring several time intervals, each time interval being the time from the end of a first frequency transmission to the end of a second frequency transmission. The two frequency transmissions are a portion of the signal protocol required by the base radio station to establish a communications link between a radio station and a base radio station. The control circuit further includes logic circuitry for computing an estimated delay time used in delaying the transmission of an identification code to the base station to establish the communication link after the end of the first frequency transmission. The estimated delay time is computed from monitoring other successful radio station protocol exchanges with the base station and measuring similar delay times and adjusting the delay time iteratively based upon the monitored delay times and any deviation between these monitored delay times and the estimated delay time.
