A recently granted patent (Publication Number: US11997532B2) outlines a method and system for congestion management on a network. The method involves identifying congested cells on the network and determining suffering users with Quality of Experience (QoE) below a configurable threshold. Traffic flow criteria of suffering users are then used to shape network traffic of other users until a predetermined threshold is reached. The system includes modules for QoE determination, analysis, and shaping to effectively manage network congestion.

Furthermore, the patent details the periodic review of suffering user QoE, identification of heavy users with high application throughput, and the continuous shaping of network traffic until user QoE improvement ceases. The system also considers factors such as application type, device type, user quota, and subscriber location in shaping traffic. Additionally, the determination of congestion based on Throughput, Round Trip Time, and Loss experienced by subscribers is a key feature. The system aims to enhance user experience by dynamically adjusting network traffic based on real-time conditions and user requirements, ultimately optimizing network performance and user satisfaction.
