A mobile telephone system multiplexes plural voice traffic channels on a single carrier using a TDMA protocol. The capacity of the mobile telephone system is increased by assigning voice traffic capacity, not on a conversation basis, but on a speech spurt basis. Accordingly, delays of undetermined duration may occur between subsequent information bursts which correspond to the transmission of speech spurts. An adjustment request regarding the power with which the information bursts are transmitted from a transmitting station to a receiving station is generated by detecting an information burst transmission at the receiving station, measuring the time which elapses following the transmission, and comparing the elapsed time with a predetermined threshold value. If the elapsed time exceeds the threshold, a further transmission is requested from the transmitting station notwithstanding the availability of any information to transmit. The power of the transmission received in response to the request is measured and a control message for requesting an adjustment to the transmission power level in response to the measurement is transmitted to the transmitting station.
In a radio telephony system having a plurality of transmitting stations, each station transmitting information bursts to another station, the bursts being transmitted on radio carrier frequencies divided into time slots for carrying the information bursts wherein delays of undetermined duration may occur between subsequent information bursts, a method for generating an adjustment request regarding the power with which the information bursts are transmitted from a transmitting station to a receiving station comprising:
