Abstract:
1. A method of performing call admission control by assigning resource units required by a new user to timeslots, the method comprising: (a) determining, for each of a plurality of timeslots, a probability that the timeslot has a signal-to-interference ratio (SIR) that will fall below a predetermined value; (b) selecting one of the plurality of timeslots having the lowest probability determined in step (a); (c) assigning the selected timeslot to a first one of the resource units; (d) determining that the selected timeslot still has the lowest probability of having a SIR that will fall below a predetermined value after being assigned to the first resource unit; (e) assigning a second one of the resource units to the selected timeslot; (f) determining a total probability for the new user that the SIR of a timeslot assigned to the resource units will fall below a predetermined value; and (g) admitting the new user if the total probability is less than a predetermined value.
