UE QoE Reporting With RAN-Visible Message and Bearer Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing QoE measurement frameworks in wireless communications networks, particularly in NR, struggle to efficiently handle both regular and RAN visible QoE reports, as they are inherently delay-insensitive and delay-sensitive, respectively, without clear mechanisms for prioritization and transmission based on criticality.
Innovation Solution
A mechanism is provided for user equipment (UE) to select message types and bearers for QoE reports based on the type and criticality of the measurement, ensuring that delay-sensitive RAN visible QoE reports are prioritized over delay-insensitive regular reports by using different message types or bearers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified QoE measurement framework is used for both regular and RAN visible QoE reports, then the framework structure is simple, but delay-sensitive RAN visible QoE reports cannot be prioritized over delay-insensitive regular reports
Solution Approach 1:
The patent segments the QoE measurement framework into separate handling paths for regular QoE reports and RAN visible QoE reports. Different message types (MeasReportAppLayer for regular, MeasurementReport for RAN visible) and bearers (SRB4 for regular, SRB1/SRB3 for RAN visible) are used to differentiate and prioritize delay-sensitive reports from delay-insensitive reports.
2Loss of time
If separate message types and bearers are used for regular and RAN visible QoE reports, then delay-sensitive reports can be prioritized, but the QoE measurement framework becomes complex
Solution Approach 1:
The patent applies local quality by assigning different properties (message types, bearers, prioritization rules) to different parts of the QoE measurement framework based on their specific requirements. RAN visible QoE reports use high-priority message types and bearers suitable for delay-sensitive traffic, while regular QoE reports use standardized lower-priority paths.
3Ease of operation
If all QoE reports are transmitted with the same priority, then the transmission mechanism is simple, but critical RAN visible QoE measurements cannot be ensured timely delivery
Solution Approach 1:
The patent introduces dynamic prioritization where the transmission priority of QoE reports is adjusted based on their type and criticality. RAN visible QoE reports are dynamically assigned higher priority through specific message types and bearers, allowing the system to adapt to different QoE measurement requirements in real-time.
4Loss of time
If RAN visible QoE reports are handled separately from regular QoE reports, then delay-sensitive reports receive timely handling, but the overall QoE measurement process becomes more complex
Solution Approach 1:
The patent implements preliminary action by pre-configuring separate message types and bearers for RAN visible QoE reports before transmission is needed. This allows the network to immediately route delay-sensitive reports through appropriate high-priority channels without requiring complex real-time decision-making, thus reducing handling time while maintaining manageable complexity.

AI summary
Embodiments herein relate to, for example, a method performed by a user equipment, UE, (10) for handling communication in a wireless communications network. The UE (10) receives from an upper layer an indication relating to a quality of experience, QoE, process; and applies the indication in one or more messages and/or for one or more bearers. The UE (10) applies the indication by selecting a message type and/or a bearer type to send the indication to a radio network node depending on a type of a QoE measurement and/or a criticality of the QoE measurement of the indication.
