ABSTRACT:
A system for scheduling access times for transmitting data traffic in a WLAN including both isochronous streams and asynchronous bursts characterized by widely varying parameter values generates a succession of service periods, each having adjustable length and including two or other number of primary access intervals. The service periods may also be adapted to include one or more asynchronous burst periods, each immediately following a primary access interval. Access times for each isochronous stream are scheduled only during a primary access interval, or an immediately following extension period. Asynchronous bursts are scheduled for access times only during asynchronous burst periods. Epoch lengths fluctuate dependent on the dynamic needs and priorities of user traffic. Thus, an access time scheduling is made available that can readily adapt WLAN access to continually changing data traffic conditions, and thereby provide QoS by scheduling access times accordingly.
