Patent ID: 7403531

Claim:
A method for controlling admission of a new isochronous data stream, within a WLAN system that transports both isochronous and asynchronous data, the method comprising: evaluating actual access times of previously admitted isochronous data streams, comprising: providing a first threshold number; determining a first value equal to the length of an individual previous service period: calculating a second value equal to an average of actual total access times used for isochronous streams during each of the first threshold number of previous service periods; determining projected access times needed by the new isochronous data stream, comprising: calculating a third value equal to, if and when the new isochronous data stream is admitted, the length of a new service period; and calculating a fourth value equal to, if and when the new isochronous data stream is admitted, a total primary access portion of the new service period; and deciding to admit or reject the new isochronous data stream based on an evaluation of the actual and projected access times.
