PURPOSE: An audio data checking method for debugging of audio data in mobile radio communication is provided to discriminate a cause for deteriorating the quality of sound by detecting the condition of audio data and decreasing the debugging interval. CONSTITUTION: When a call between a mobile terminal and a wire terminal is set, it is determined whether audio loop back instruction is inputted(S103). If audio loop back instruction is inputted, an audio signal is inputted via the mobile terminal(S104). The mobile terminal transforms the audio signal to QCELP data, and transmits to a base station(S105). The base station transmits the QCELP data to the TSB of a control station by a predetermined period(S106). The TSB stores sequentially an inner buffer with the QCELP data(S107). The stored QCELP data is read by a predetermined period, and transmitted to the mobile terminal via the base station.
