UE QoE Reporting Prioritization During RAN Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio access network (RAN) overload can cause the pause of all quality of experience (QoE) measurement configurations, including high-priority reports, leading to incomplete network deployment or optimization, which affects the network's ability to pinpoint specific performance issues.
Innovation Solution
User equipment (UE) implements a pause/resume mechanism for QoE reporting based on event-triggered information and report selection criteria, allowing selective partial reporting during RAN overload to prioritize high-priority or critical QoE measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RAN pauses all QoE measurement reporting during overload, then network overload is reduced, but high-priority QoE reports are lost affecting network optimization capability
Solution Approach 1:
The patent segments QoE measurement configurations into different priority levels (first priority and second priority). During RAN overload, the network equipment selectively pauses only lower-priority measurements while maintaining higher-priority measurements. This segmentation allows differential treatment of QoE reports based on their importance, ensuring critical performance data continues to be collected even when the network is overloaded.
Solution Approach 2:
The patent applies local quality by assigning different qualities (priorities) to different QoE measurement configurations. Each QoE measurement configuration is tagged with a priority level, and the network equipment makes localized decisions about which measurements to pause or resume based on current network conditions and the specific priority of each measurement type. This allows critical local measurements to continue while non-critical ones are paused.
2Loss of energy
If RAN pauses all QoE measurement configurations during overload, then signaling load is reduced, but measurement completeness is compromised
Solution Approach 1:
The patent implements partial action by selectively pausing only a subset of QoE measurement configurations (those with lower priority) during RAN overload, rather than pausing all measurements. The network equipment evaluates the current overload condition and the priority levels of pending measurements, then partially suspends reporting for non-critical measurements while maintaining reporting for critical measurements. This partial approach reduces signaling load sufficiently to manage overload while preserving essential measurement data.
3Stability of the object's composition
If RAN stops new QoE measurement configurations during overload, then network stability is improved, but optimization granularity is reduced
Solution Approach 1:
The patent introduces dynamic adaptability by allowing the network equipment to flexibly adjust QoE measurement configuration acceptance based on real-time network conditions and priority levels. During moderate overload, the network can still accept new high-priority measurement configurations while pausing lower-priority ones. The system dynamically evaluates incoming measurement configuration requests against current network state and priority criteria, enabling adaptive response to varying overload conditions while maintaining network stability.
Data Source
AI summary
A user equipment and a method related to reporting management are provided. In the method, event-triggered information is received for a quality of experience (QoE) measurement configuration. A pause indication is received. To send or pause one or more QoE reports is determined based on the event-triggered information. The QoE report is associated with the QoE measurement configuration.
