ABSTRACT:
A subpacket control system used in a time division multiple access system in which a hub station communicates with a plurality of terminal stations via a satellite. When a datum to be transmitted from a terminal station to a hub station has a length exceeding one slot length, the datum is divided into subpackets each having one time slot length, and subpacket information indicating the sequential number of each subpacket in the subpackets is added to the subpacket. A plurality of subpackets are transmitted to the hub station without waiting for a return of an answer back with respect to a first subpacket. On the basis of the subpacket information, the hub station controls reservation access permission.
