Abstract: PURPOSE: A method for controlling power of a mobile communication terminal is provided to dynamically control an APC(Automatic Power Control) parameter by interworking with a base station while making a call, thereby improving speech quality and lowering a call drop probability. CONSTITUTION: A base station downloads an ordered power offset command and an ordered MS power level command to a terminal.

The terminal sets transmission power by applying the stored APC value to a current multi frame, and uploads a power offset value and an MS power level through an uplink channel. The base station applies differences between an actual MS power level and a measured level to the ordered power offset command, and downloads an applied value to the terminal. The terminal stores an APC value generated when the ordered power offset command drops less than a predetermined threshold value.
