FIELD: inserting control information about transmission window at radio link control level.
SUBSTANCE: in order to eliminate such drawback as transfer of control information about transmission window only once when determining need for its transfer according to initialization protocol, RLS receiving end periodically finds out if control information about transmission window should be inserted, then it transmits SUFI information about window size once every definite interval, transfers same SUFI information about window size many definite times, and restarts new process upon completion of transfer. Novelty is that sending RLC end can frequently receive SUFI information about window size by periodically inserting SUFI information about window size on RLC receiving end to enhance reliability of transferring SUFI information about window size and to eliminate drawbacks in method for transmitting SUFI information about window size inherent to state of the art. Transmission window size can be adjusted in due time and reduction in effectiveness of using bandwidth for RLC protocol can be eliminated.
EFFECT: provision for eliminating information loss and data transfer control failure.
