A method for detecting QoS, including: obtaining information in packets transferred between MGWs, and obtaining packet loss ratio, jitter and delay of each channel of users in an office direction in communication with the MGWs through the obtained information; obtaining average packet loss ratio, average delay and average jitter of the office direction according to the packet loss ratio, the jitter and the delay of each channel of users; and obtaining overall QoS of the office direction according to the average packet loss ratio, the average delay and the average jitter of the office direction as well as the weight coefficient of the foregoing three indices affecting the voice quality.
