FIELD: information technologies.
SUBSTANCE: transmitting device codes voice superframes DMR using coding parameters, and sends coding parameters in at least one of voice superframes with the help of the following: identification of a selected number of bits from multiple frames of a vocoder of a voice superframe; replacement of each of identified bits with an appropriate bit of the first coding parameter; placement of at least one coding parameter in the field of inbuilt alarm of the voice superframe; and transmission of a voice superframe with coding parameters into a receiving device. The receiving device extracts coding parameters, which may be an identifier of a key, an identifier of a logic and an initialisation vector for use in decoded messages from the transmitting device.
EFFECT: expansion of functional possibilities due to transfer of coding parameters, which may be implemented in a DMR system.
