Abstract
A method of generating optimal packet workload for achieving a balance between maximizing cell throughput and fairness across multiple users in UMTS/HSPA Network is disclosed. The packet scheduler of the current invention enhances the performance of other schedulers, such as Proportionally Fair Scheduler in NodeB and RNC in UMTS/HSPA Networks by monitoring recent RAN bandwidth to each mobile device, and increasing buffer occupancy of high rate data-flows in the RAN devices. The scheduler uses the desired performance goals of maximum cell throughput and fairness at various network congestion levels, and controls egress burst rate while delivering packets to the RAN (Radio Access Network).
