Patent ID: 7899482

Claim:
A transmission power target value variable control apparatus characterized by comprising: target value generation means for generating, on the basis of an actual reception quality in a mobile communication terminal, a target value to be used to control transmission power of a base station from the mobile communication terminal; target value correction means for adding a correction value to the target value generated by said target value generation means in a predetermined case, characterized in that when the mobile communication terminal exists in a service area of a predetermined specific communication carrier, said target value correction means adds the correction value to the target value; detection means for detecting, from a reception signal, an identifier of a communication carrier of a service area where the mobile communication terminal currently exists; and control means for comparing the identifier detected by said detection means with an identifier of the specific communication carrier and, when the identifiers coincide with each other, outputs a control signal to said target value correction means, wherein said target value correction means adds the correction value to the target value upon receiving the control signal.
