Abstract
A cellular radio system and a method for adjusting transmit power during call set-up. The system comprises at least one base station and a group of subscriber equipment communicating with one or more of the base stations. The signal-to-noise ratio between the subscriber equipment and a base station is estimated before an actual connection is set up. In order that the new connection not interfere with the existing connections, a desired power transmit value with which the desired signal-to-noise ratio is obtained is calculated for the transmit power of the transmitter. An initial value for the transmit power is calculated by means of the power-control parameters of the system and a given time constant and the transmission is started with the initial value. The transmit power in increased from the initial value to the desired power transmit value during a given time constant.
