Abstract

PURPOSE:To increase the line utilization rate, by giving the slot reservation number of priority, slot using number in the next frame, and slot reservation number of ordinary class to the reservation burst transmitted from a plurality of earth stations of a satellite communication line. CONSTITUTION:The communication line of a communication satellite 1 and earth stations 2-4 is constituted with incoming channels 5-7 and an outgoing channel 8. Each earth station transmits reservation bursts 12-14 in time division. The reservation bursts are transmitted with a priority slot SL reservation number 21, priority SL number 21 requesting the SL assignment of the priority class actually in the next one frame, and ordinary SL reservation number 23. The earth station 2 assigns received bursts 12-14 from the channel 8 from the head SL in one frame by sequentially checking the priority SL using number 22 of each earth station. Next, the assignment of the ordinary class SL is made with the priority. Thus, even with the SL reservation of priority class, if an SL not transmitting data burst is present, the transmission of the data burst of ordinary class can be made, allowing to use lines without waste.
