Abstract
PURPOSE:To improve the utilizing efficiency of a channel by controlling the degree of appearance of transmission interval between transmission timing signals in response to the length of same information signal even when plural terminal stations are going to send an information signal of nearly the same length in the same time zone. CONSTITUTION:A central station 21 is provided with a means 12 sending plural transmission timing signals at plural different transmission intervals, and means 14, 15 monitoring the traffic of a burst signal sent by plural terminal stations 22 respectively. Each of plural terminal stations 22 is provided with a means 33 discriminating plural different transmission intervals of the received transmission timing signal and a means 36 sending the information signal in response to the transmission interval of the sent timing signal as a burst signal based on the result of discrimination. The central station 21 controls the rate of appearance of the different transmission interval between plural transmission timing signals from the traffic of the burst signal. Thus, in sending the packet of various length, the channel utilizing efficiency is improved without requiring a complicated equipment.
