ABSTRACT:
In a pocket switching communications system of the type in which each station sends its packet into an unoccupied block within a frame, the retransmission interval is determined by generating a random number, weighting the random number in accordance with the number of collisions which the station has encountered since it first requested transmission and/or the degree of congestion monitored in the frame in which the most recent collision occurred. The retransmission interval is then determined in accordance with the weighted number.
