FIELD: physics; communications.
SUBSTANCE: invention relates to a method and device for accessing message memory of a communication module in modes of entering data into message memory or extracting data therefrom. The method of accessing message memory of a communication module in the said modes involves entering data into the corresponding main buffer memory and switching between modes of accessing the main buffer memory and shadow memory with possibility of entering next data into the shadow memory and simultaneous extraction from the main buffer memory already entered data in a specified direction. The message memory is connected to a buffer memory unit. Data are transferred in the first direction - into the message memory, and in the second direction - from the message memory. For data transferred in the first direction, the buffer memory unit has an input buffer, and an output buffer for data transferred in the second direction. Each of the said buffers is divided into two parts: main buffer memory and the associated shadow memory.
EFFECT: optimisation of the process of transferring data between the processor of user equipment and message memory with relation to transfer rate and providing data integrity.
