FIELD: physics, communications.
SUBSTANCE: invention relates to the radio communication and is intended for the interaction of the first station with the second station. For that purpose, the first station uses the first communication plan and contains the first coder and the first decoder, and the second station uses the second communication plan and contains the second coder and the second decoder, the communication between the first and second stations is implemented by transmitting the signal coding parameters related to the audio signal from the coder of one of the stations (first or second) to the other station decoder. The audio signal is classified in order to determine if the signal coding parameters should be transmitted from the coder of one station to the other station decoder using the first communication mode, in which the full transmission rate is used for the transmission of the signal coding parameters. If the audio signal classification determines that the signal coding parameters should be transmitted using the first communication mode and if a request for transmitting the signal coding parameters from the coder of one station to the other station decoder using the second communication mode intended for decreasing the transmission rate during the signal coding parameters transmission is received, part of the signal coding parameters is deleted from the coder of one station, while the remaining signal coding parameters are transmitted to the other station decoder using the second communication mode. The deleted part of the signal coding parameters is recovered before the other station decoder decodes the signal coding parameters.
EFFECT: increase in reliability of radio communication.
