Ranking-Based Scheduling for Wireless QoS Compliance

The patent implements a feedback mechanism where the scheduler continuously monitors actual bandwidth shares received by each traffic class and compares them against target bandwidth shares. Based on this feedback, the scheduler dynamically adjusts service priority weights for different traffic classes to correct deviations and ensure QoS compliance while maintaining system capacity.

The patent introduces dynamic service priority weights that adapt to changing network conditions and actual bandwidth share deviations. Instead of using fixed priorities, the system continuously adjusts the weight assigned to each traffic class based on real-time performance measurements, allowing the scheduler to respond to rapid radio link quality variations and maintain both capacity and QoS compliance.

The patent implements a self-adjusting scheduling mechanism where the system automatically monitors its own performance and corrects deviations without external intervention. The scheduler computes actual bandwidth shares, compares them to targets, and autonomously adjusts service priority weights based on predefined adjustment rules, reducing the need for complex external control mechanisms.

The patent changes the scheduling parameter (service priority weight) dynamically based on measured bandwidth share deviations. By adjusting this single key parameter according to simple proportional rules, the system achieves QoS compliance without introducing complex multi-parameter control algorithms, keeping the scheduling logic relatively simple while effective.
