Abstract: PROBLEM TO BE SOLVED: To avoid the wasteful use of the channel resource of a communication system by minimizing the number of occurring times of time-outs. SOLUTION: In a method for controlling time-out of communication protocol, the length of the time-out is decided, based on the sum of an average channel delay and the quadruple of the deviation of a channel delay. When the deviation of the channel delay is increased by introducing a delay to a communication channel, the time required for the time-out becomes longer. Consequently, the channel resource of the communication system can be utilized effectively, because the length of the time-out dramatically decreases and wasteful ramp up times become shorter.
