Abstract: PURPOSE: A method for measuring a receiving sensitivity of a base transceiver station(BTS) in a communication system is provided to measure the receiving sensitivity through a testing terminal mounted on the BTS, a variable attenuator in a BTS diagnostic terminal unit(BDTU), and a radio frequency(RF) processor in an unmanned method, so as to maintain an optical state of a BTS system. CONSTITUTION: A base transceiver station(BTS) diagnostic terminal unit(BDTU) firstly sets up an attenuating value of a variable attenuator, and measures attenuating values between a testing terminal and a radio frequency(RF) processor to store the attenuating values(S1). The BDTU connects a testing call capable of measuring a receiving state to the testing terminal, and turns off a power controlling function not to change a transmission output of the testing terminal(S2). A transcoder block(TSB) of a control station analyzes receiving data received in the control station(S3), and decides whether the receiving data is superior(S4). If so, the TSB increases an attenuating value of the variable attenuator as one step until the receiving data is inferior, and continuously analyzes the receiving data(S5). If the receiving data is inferior, the TSB adds the attenuating values between the testing terminal and the RF processor to the attenuating value of the variable attenuator, and measures a receiving sensitivity of the final BTS(S6).
