Method and system for performing call admission control in the uplink for third generation wireless communication systems
First Claim
1. A method for performing call admission control comprising:
- assigning resource units required by a new user to timeslots based on outage probability of each individual timeslot;
computing a total outage probability for the new user;
determining whether the total outage probability is below a predetermined value; and
admitting the new user where the determination is positive.

Abstract
A method and system for performing call admission control in wireless communication systems is disclosed. Resource units required by a new user are assigned based on an outage probability of each uplink timeslot. The outage probability of each timeslot is updated as the resource units are assigned so that each resource unit assignment results in the lowest possible contribution to total outage probability. Once all of the resource units are assigned, the total outage probability is computed based on the resource allocation. If the total outage probability is below a predetermined value, the new user is admitted. If the total outage probability is above the predetermined value, the new user is rejected.

4. A method for performing call admission control comprising:
-
computing an outage probability for each uplink timeslot;
assigning a first resource unit required by a new user to the timeslot having the lowest outage probability;
assigning subsequent resource units required by the new user to timeslots that will result in the lowest total outage probability for the new user;
computing a total outage probability based on which timeslots have been assigned resource units; and
admitting the new user if the total outage probability is below a predetermined value. - View Dependent Claims (5)

6. A method for performing call admission control comprising:
-
computing an outage probability for each timeslot;
identifying a timeslot having the lowest outage probability;
assigning a first resource unit required by a new user to the identified timeslot;
assigning subsequent resource units required by the new user to a group of timeslots that minimizes total outage probability of the new user;
computing a total outage probability based on which timeslots have been assigned resource units; and
admitting the new user if total outage probability is less than a predetermined value. - View Dependent Claims (7, 8)
