Abstract: PURPOSE: A method for measuring a transmission standing-wave ratio amending the call state of a base station is provided to exclude a maximum value and a minimal value from measured transmission standing-wave ratios, and to assign a weight to an overlapped value, thereby measuring a transmission standing-wave ratio without a service disconnection. CONSTITUTION: A system sequentially measures the first power and the second power corresponding to a forward power and a reverse power, respectively(S100,S110). The system measures a standing-wave ratio based on the first and second powers, and stores the measured standing-wave ratio in a memory with the first and second powers. The system checks the frequency of measuring the standing-wave ratio(S130). If the measuring and the storing are completed, the system erases a maximum value and a minimal value from stored standing-wave ratio data(S150), and detects an overlapped value from the data(S160). The system assigns a weight to a standing-wave ratio having the overlapped value(S170), and calculates an average in consideration of the weight of the standing-wave ratio and other standing-wave ratios(S180).
