Variable Configuration Device for Proactive QoS Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing quality of service (QoS) in 3GPP networks often lead to negative user experiences due to late notifications of QoS violations, resulting in disruptions that could have been prevented with earlier intervention.
Innovation Solution
A variable configuration method and device that utilize incident prediction notifications from the network to proactively determine and output configuration variables, allowing for preemptive adjustments to QoS settings before a predicted QoS violation occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system waits for QoS violation to be detected and then issues notification, then the detection accuracy is improved, but the response time is delayed causing negative user experience
Solution Approach 1:
The system performs preliminary actions by predicting potential QoS violations before they actually occur. The PCF receives incident prediction notifications and proactively adjusts configuration variables (such as QoS parameters, resource allocation) in advance, modifying the PDU session configuration before the violation happens to prevent service disruption and maintain user experience.
2Reliability
If the system proactively adjusts QoS settings before violation occurs, then user experience is improved, but the system complexity increases
Solution Approach 1:
The PCF acts as an intermediary between the RAN and the PDU session management. It receives incident prediction notifications from the RAN, processes the prediction information, determines appropriate configuration variables, and outputs the modified configuration. This intermediary role simplifies the overall system architecture by centralizing the predictive QoS management function in a dedicated component rather than distributing complexity across multiple elements.

AI summary
A variable configuration method and a variable configuration device thereof are disclosed. The variable configuration method for the variable configuration device includes receiving an incident prediction notification from a network at a first time instant, determining at least one variable at a second time instant in response to the incident prediction notification, and outputting the at least one variable at a third time instant. The incident prediction notification is used to instruct the variable configuration device to determine the at least one variable to respond to a quality of service (QoS) violation prediction at a fourth time instant later than the third time instant.
