Abstract:
1. A method for scheduling access times for transmitting data frames from a first transmission point in a WLAN to a second transmission point therein, wherein data frame traffic includes both isochronous streams and asynchronous bursts and is characterized by variations in specified parameter values, the method comprising: defining a succession of service periods, each service period including a specified number of isochronous epochs; adapting at least one of the service periods to include at least one asynchronous epoch, each asynchronous epoch immediately following an isochronous epoch of the same service period and each asynchronous epoch is followed by at least one isochronous epoch of the same service period; and scheduling the access times for the isochronous streams only during the isochronous epochs, and for the asynchronous bursts only during the asynchronous epochs, wherein the lengths of the isochronous and asynchronous epochs fluctuate dependent on the dynamic needs and priorities of user traffic.
