RAN Node QoE Measurement Reporting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in ensuring uninterrupted Quality of Experience (QoE) measurement collection and reporting, particularly during network overload conditions, which can lead to insufficient or inadequate data collection and increased network interference.
Innovation Solution
Implementing signaling mechanisms in the radio access network (RAN) to stop QoE measurements during overload and notify the core network management system, allowing the management system to adjust measurement collection strategies accordingly, such as increasing measurement areas or durations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If QoE measurement collection is performed continuously in wireless networks, then measurement data availability is improved, but network overload and interference increase
Solution Approach 1:
The patent implements discontinuous QoE measurement collection where the RAN node periodically activates and deactivates measurement reporting based on network conditions. During non-overload periods, measurements are collected; during overload periods, collection is suspended. This periodic on/off action maintains data availability while preventing network overload, directly resolving the contradiction between continuous measurement and network health.
Solution Approach 2:
The patent establishes a feedback mechanism where the RAN node monitors network overload conditions and sends notifications to the management system. When overload is detected, the RAN node activates QoE measurement discontinuity and notifies the management system, which then adjusts measurement configurations. This closed-loop feedback enables dynamic adaptation of measurement collection to network conditions, balancing data availability with network load.
2Object-affected harmful factors
If QoE measurement reporting is stopped during network overload, then network interference is reduced, but measurement data availability decreases
Solution Approach 1:
The patent applies preliminary action by having the RAN node proactively activate QoE measurement discontinuity before overload severely impacts network performance. The node detects early signs of overload and preemptively suspends measurement reporting, preventing further degradation. This advance action reduces network interference while minimizing data loss by resuming measurements once conditions improve.
Solution Approach 2:
The management system receives notifications from the RAN node about discontinuity activation and uses this feedback to adjust measurement configurations. The management system can modify measurement parameters, extend measurement durations, or expand measurement areas to compensate for interrupted collection, thereby maintaining overall data availability despite temporary suspensions during overload periods.
3Reliability
If the management system adjusts measurement collection strategies proactively, then measurement data quality is improved, but system complexity increases
Solution Approach 1:
The patent extracts the complex measurement management functions from the RAN node and concentrates them in the management system. The RAN node's role is simplified to detecting overload conditions and sending notifications, while the management system handles the complex tasks of adjusting measurement configurations, extending durations, and expanding areas. This extraction reduces RAN node complexity while maintaining proactive measurement quality through centralized management.
Solution Approach 2:
The management system acts as an intermediary between the RAN node and the QoE measurement collection process. It receives notifications from the RAN node about network conditions and mediates the adjustment of measurement parameters accordingly. This intermediary role allows complex adaptive measurement strategies to be implemented without burdening the RAN node with complex decision-making logic, thus improving data quality while managing system complexity.
