摘要：A network communication system is provided whereby communication stations

can obtain priority for data transmission to communicate directly with each other in acontention-free mode communication period independently of a polling operation of thecontrol station. The control station emits a series of beacons at equal intervals to initiatecontention-free mode communication at the completion of a predetermined number ofbeacons. During the maximum contention-free mode communication period a contention-free communication operation is initiated, for allowing contention-free modetransmission, by a polling operation by the control station. A series of time-slots isimaginarily provided at equal intervals from the start of the contention-free periodthroughout the maximum contention-free period. A communication station conducts acall-connection procedure in order to obtain a priority for data transmission in a given setof time-slots.
