Abstract: PURPOSE: A method for controlling an inner power by corresponding to a delay time of a portable terminal is provided to calculate an inner delay value by detecting a self operational delay of a terminal, and to selectively receive a TPC(Transmit Power Control) command by using the calculated value, thereby receiving a target transmit power. CONSTITUTION: A portable terminal sets a standard communication environment in a development stage, forms an inner power control loop, and measures a delay time until a TPC command received from a base station is internally applied to the portable terminal. The portable terminal is applied with the measured delay time to perform a TPC function by using the TPC command only, which is applied at an interval of the corresponding delay time. When measuring the delay time, an output power in accordance with the first TPC applied from the base station is controlled while basic operational software is mounted on the terminal. The number of delay slots is measured through a dedicated development equipment from a moment when the first TPC is received to a moment when the output power is updated.
