In addition, according to another object of the present invention, in a mobile communication system including a DM terminal, an operating agent terminal and an SMS center, and provides a mobile communication service, each signal level is received and stored from a plurality of DM terminals at regular intervals. After calculating the average value of the signal level to generate the on-site quality reference level, check whether the on-site quality reference level is two or more, and if the result is two or more, calculate the average value of the on-site quality reference level to determine the quality index. After generating the signal level from the DM terminal, and confirming whether or not the specific value of the quality indicator, and if the result is greater than or equal to the specified value, the wireless environment to send the field check SMS to the operating personnel terminal using the SMS center It provides a check message notification system according to a wireless environment detection, comprising a detection server.
