QoE Reporting Priority Control During NR Network Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QoE measurement systems in New Radio (NR) face challenges in managing multiple simultaneous measurements, leading to reporting storms during network overload, with no effective control over priority settings, resulting in potential interruptions and inefficiencies.
Innovation Solution
Implementing a priority setting mechanism where the gNB generates indications based on QoE measurement priorities, allowing the UE to suspend or resume reporting based on predefined thresholds, ensuring high-priority measurements are maintained during network overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gNB controls QoE measurement reporting to manage overload situations, then the reliability of high-priority reporting is improved, but the device complexity increases due to the need for priority-based indication generation and transmission
Solution Approach 1:
The QoE measurement reporting is segmented by priority levels. The gNB generates separate indications for different priority levels (first priority, second priority, etc.), allowing selective control of reporting based on overload conditions. This segmentation enables the system to maintain high-priority reporting reliability while managing overall system complexity through structured, priority-based control.
Solution Approach 2:
The gNB changes the parameter of indication transmission based on overload levels. When overload is detected, the gNB modifies which priority levels receive reporting indications, effectively using parameter changes (priority level selection) to maintain reliability for critical measurements while adapting to system constraints.
2Productivity
If the gNB suspends low- and middle-priority QoE measurements during overload, then the productivity of high-priority reporting is improved, but the loss of information increases for suspended measurements
Solution Approach 1:
The gNB performs preliminary actions by generating and transmitting indications to suspend or resume measurements before overload conditions fully impact the system. This allows the UE to proactively adjust measurement activities, maintaining high-priority reporting productivity while minimizing information loss through timely resumption of suspended measurements when conditions improve.
Solution Approach 2:
The measurement reporting system is made dynamic through the gNB's ability to generate different indications based on current overload conditions. The system can dynamically suspend or resume measurements of different priority levels, allowing flexibility in managing productivity versus information loss based on real-time network state.
3Ease of operation
If the UE autonomously determines reporting based on received indications, then the ease of operation is improved, but the measurement precision may be affected by incorrect interpretation of priority-based indications
Solution Approach 1:
The gNB provides feedback through structured indications that convey priority-based reporting requirements to the UE. The UE uses these feedback signals to autonomously determine which measurements to report, suspending or resuming based on clear priority directives. This feedback mechanism maintains measurement precision by ensuring the UE correctly interprets gNB intentions regarding measurement priority and reporting requirements.

AI summary
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of priority setting for Quality of Experience (QoE). The method comprises receiving, from a second device, an indication associated with reporting at least one QoE measurement to be performed at the first device, the indication generated by the second device based on respective priorities of the at least one QoE measurement and determining the reporting of the at least one QoE measurement based on the indication. In this way, the gNB have capability to control configured QoE measurement reporting of the UE and the QoE reporting of the UE with high priority can be maintained without interruption in low-level and middle-level overload situation.
