<p>The invention relates to a cellular radio system and a method for adjusting transmit power during call set-up in a cellular radio system comprising in each cell at least one base station (100) and a group of subscriber equipments (108-112) communicating with one or several base stations. In the method, the signal-to-noise ratio between a subscriber equipement and a base station is estimated before an actual connection is set up. In order that the new connection would not interfere with the existing connections, in the method according to the invention a value with which the desired signal-to-noise ratio is obtained is calculated for the transmit power of the transmitter (100, 108-112). A certain initial value is calculated for the transmit power by means of the power-control parameters of the system and a given time constant, and the transmission is started with the calculated initial value, and the transmit power is increased from the initial power to said value during the given time constant.</p> |
