Abstract:
1. A power control apparatus for controlling a power of a mobile station for use in a wireless mobile telecommunication system, the power control apparatus comprising: a telecommunication device to receive data quality information transmitted from the mobile station in a radio resource control layer; a judgment device to repeatedly judge a reception quality of the mobile station by using the received data quality information, to change a first target power quality which is compared with a power quality measured in the mobile station and a second target power quality which is compared with a power quality measured in a base station based on a judgment result, and to stop changing the first target power quality and the second target power quality when the reception quality is not improved by previous instructions to change the first target power quality and the second target power quality; and a notification device to transmit the changed first target power quality to the mobile station, to request the mobile station to change the first target power quality, to transmit the changed second target power quality to the base station, and to request the base station to change the second target power quality, wherein the judgment device calculates a first indicator of the reception quality by using first data quality information presently received from the mobile station, calculates a second indicator of the reception quality by using second data quality information previously received from the mobile station and judges the reception quality by comparing a difference of the calculated first and second indicators with a judgment value.
