Abstract:
1. A method for admission control in wireless communications, wherein data is prioritized by access categories, the method comprising: calculating a transmission budget for each access category (AC) at an access point (AP); calculating a total transmission budget for all ACs requiring admission control; receiving a traffic stream admission request at the AP; calculating a medium time value for the traffic stream at the AP, the medium time value being based on the admission request; comparing the medium time value to the transmission budget for the AC corresponding to the traffic stream and the total transmission budget; accepting the traffic stream if the medium time value is not greater than both the transmission budget for the AC corresponding to the traffic stream and the total transmission budget; and rejecting the traffic stream if the medium time value is greater than one of the transmission budget for the AC corresponding to the traffic stream and the total transmission budget.
