User-plane congestion management in wireless networks
The granted patent (Publication Number: US11924680B2) discloses a method implemented by a first network node in a network. The method involves receiving a request from a second network node to monitor resource usage associated with at least one wireless transmit/receive unit (WTRU). The request includes a threshold and is related to a specific service and quality of service (QoS). The first network node monitors the resource usage, determines if the threshold is exceeded, and sends a report to the second network node accordingly. Additionally, the method includes actions such as performing policy and charging execution functions, providing updated control rules and quality of service rules, initiating session termination, and implementing congestion mitigation strategies based on the reported resource usage.
Furthermore, the patent also describes a first network node comprising a processor and a transceiver that is configured to receive requests from a second network node to monitor resource usage, determine if the threshold is exceeded, and send reports based on the determination. The first network node can also perform policy and charging execution functions and handle separate thresholds for low-priority services. Another aspect of the patent involves a method where the first network node sends a request to the second network node to monitor resource usage, receives a report indicating if the threshold is exceeded, and performs policy and charging rules functions. This method also allows for separate thresholds for low-priority services, emphasizing the importance of efficient resource management and quality of service in network operations.
