Wireless network system and communication method employing both contention mode and contention-free mode |
摘要 |
A network communication system is provided whereby communication stations can obtain priority for data transmission to communicate directly with each other in a contention-free mode communication period independently of a polling operation of the control station. The control station emits a series of beacons at equal intervals to initiate contention-free mode communication at the completion of a predetermined number of beacons. During the maximum contention-free mode communication period a contention-free communication operation is initiated, for allowing contention-free mode transmission, by a polling operation by the control station. A series of time-slots is imaginarily provided at equal intervals from the start of the contention-free period throughout the maximum contention-free period. A communication station conducts a call-connection procedure in order to obtain a priority for data transmission in a given set of time-slots.
