Abstract: PURPOSE: A method for restricting forward calls and estimating transmission power in a mobile communication base station, is provided to estimate a value of transmission power by using a value measured in a base station test device and a digital gain of a modulator and using a path error of a wireless frequency stored in the base station test device, and to compare the measured value with a pre-determined critical value so as to restrict calls. In the method, total transmission power of the base station is correctly calculated so as to correctly detect an overload of a base station system. CONSTITUTION: Transmission power of a base station measured by a base station test device is read. Whether the transmission power is bigger than a critical value is confirmed. If so, the transmission power is stored. If a call is generated in the base station, digital gain power is calculated by using an allocated digital gain for a corresponding call. The transmission power is combined with the digital gain power to calculate total transmission power by the call. The total transmission power of the base station is compared with the pre-determined critical value for restricting calls of the base station.
