Zusammenfassung:	A VSWR(Voltage Standing Wave Ratio) measuring device in a mobile communication system is provided to measure a VSWR by measuring the strength of terminal transmission signals as obtaining the reception sensitivity of a base station by connecting calls of a terminal and the base station, thereby eliminating inconvenience. A directional coupler(314) delivers terminal transmission signals inputted from a VSWR measuring device(302) to an RF(Radio Frequency) receiver(318) of a base station(316) by using a direct path and a reflection path. When calls are connected through the direct and reflection paths between the base station and a terminal(300), the VSWR measuring device measures base station reception sensitivity of each path by using the terminal transmission signals, and calculates a VSWR by using the measured sensitivity.
