Abstract
A dynamic frame length slotted ALOHA communication system has a central station which monitors the traffic congestion and determines the optimum frame length. This is transmitted to the sub-stations in the form of a service information message when there is to be a change in the frame length but not, as is conventional, at the beginning of each frame. The amount of time available for the useful transmission of communication messages is thus optimized.
