1. A method of controlling the transmission power associated with a first air interface channel, the method comprising:
determining a quality of service measure for a signal to be transmitted on a second air interface channel;
determining an interference measure corresponding to the interference on said second air interface channel which will be caused by transmissions on said first air interface channel;
requesting the changing of the transmission power associated with the first air interface channel when the signal is to be transmitted on the second air interface channel, when the quality of service measure is above a predetermined value and when the interference measure is above a predetermined value for said quality of service value.
