A transmission power control apparatus is adapted to control a reference value for controlling a transmission power of a mobile terminal equipment based on a reception quality of a plurality of radio access bearers at a base station apparatus, with respect to a physical channel to which the plurality of radio access bearers are mapped, when making a radio connection between the mobile terminal equipment and the base station apparatus in a mobile communication system. The transmission power control apparatus includes a judging part configured to judge whether or not a radio access bearer that is a monitoring target of the reception quality is an audio transmission radio access bearer in a silent state, based on multiplexed information; and a switching part configured to switch the radio access bearer that is the monitoring target of the reception quality to a radio access bearer other than the audio transmission radio access bearer in the silent state, if the judging part judges that the radio access bearer than is the monitoring target of the reception quality is the audio transmission radio access bearer in the silent state. The reference value for controlling the transmission power of the mobile terminal equipment is controlled based on a reception quality of the radio access bearer other than the audio transmission radio access bearer in the silent state.
