Claim 0:
1. An operating method of a transmission terminal for transmitting an audio signal, the method comprising:
determining a first bit rate range for a sending direction of the transmission terminal and a second bit rate range for a receiving direction of the transmission terminal;
transmitting at least one parameter indicating the first bit rate range and the second bit rate range to a reception terminal;
receiving combination determination information from the reception terminal;
compressing the audio signal according to the received combination determination information; and
transmitting the compressed audio signal to the reception terminal,
wherein the combination determination information is determined based on a third bit rate range for a receiving direction of the reception terminal, by the reception terminal, and
wherein when the first bit rate range and the second bit rate range are the same, one parameter indicating the first bit rate range and the second bit rate range is transmitted to the reception terminal, and
when the first bit rate range and the second bit rate range are different, two parameters indicating the first bit rate range and the second bit rate range respectively are transmitted to the reception terminal.
