The present invention relates to a method of regulating or adjusting the transmission power when transmitting signals between a mobile station and a base station in a digital mobile telephony system. The output power is regulated with the intention of constantly maintaining the transmission power at an optimum level, by which is meant that the transmission power is as low as possible such as to prevent unnecessary disturbance of neighbouring channels transmitting information on the same frequency, but sufficiently high for the transmitted information to be interpreted in the receiver. The measurement values of signal strength and signal-transmission quality are collected, the mean values of the signal strength and transmission quality are calculated on the basis of the collected measurement values. kith the aid of the calculated mean values, there is calculated an anticipated value of signal strength and transmission quality *(*Z_QQ) at the next time-point, provided that the transmission power is maintained unchanged in relation to the transmission power at the present or instant time-point. Finally, the transmission power at the next time-point is regulated on the basis of these anticipated values. The transmission power is increased when the anticipated transmission quality is poorer than the desired quality and is increased when the anticipated quality is higher than the highest permitted quality or when the anticipated signal strength is greater than the maximum permitted value. The transmission power is otherwise maintained unchanged.
