Solution Overview

Problem

Existing wireless communication systems face challenges in managing Quality of Experience (QoE) measurement collection and reporting, especially during mobility and state transitions, which can lead to intermittent quality degradation affecting real-time services.

Innovation Solution

A network node implements Quality of Experience (QoE) measurement collection and supports configuration and reporting for multiple simultaneous QoE measurements. The Radio Access Network (RAN) uses a mapping between reference IDs and QoE configurations to identify measurements and manage activation, modification, and release functionality, including pausing and resuming QoE reporting during handover scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If QoE measurement collection and reporting is continuously performed during handover, then measurement precision is improved, but device complexity increases and reliability deteriorates due to intermittent quality degradation

Engineering Contradiction:

ImproveQoE measurement precisionVSAvoidservice quality reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The system performs preliminary actions by pausing QoE measurement collection before handover occurs and resuming it after handover completion. This prevents measurement interruptions during critical handover phases, thereby maintaining measurement precision while avoiding the complexity and reliability issues associated with continuous measurement during state transitions

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements periodic measurement collection by enabling QoE measurements during stable connected states and pausing them during handover transitions. This periodic approach ensures measurements are taken when reliable while reducing system complexity and improving overall service reliability by avoiding measurements during unstable states

Inventive Principle:

Principle #19Periodic action

2Reliability

If QoE reporting is paused during handover, then reliability is improved by avoiding intermittent quality degradation, but measurement precision deteriorates due to measurement gaps

Engineering Contradiction:

Improveservice quality reliabilityVSAvoidQoE measurement precision

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The system resumes QoE measurement collection immediately after handover completion as a preliminary action to capture post-handover quality metrics. This ensures measurement precision is restored without permanent gaps, while maintaining reliability by pausing only during the actual handover transition period

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuity of useful measurement action by pausing QoE collection only during handover and immediately resuming afterward. This minimizes measurement gaps while ensuring reliability during transitions, achieving both high reliability and acceptable measurement precision through brief, controlled interruptions

Inventive Principle:

Principle #20Continuity of useful action

3Adaptability or versatility

If multiple simultaneous QoE measurements are supported, then adaptability is improved for different service types, but device complexity increases

Engineering Contradiction:

Improveservice type adaptabilityVSAvoidQoE management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments QoE measurement management by maintaining separate QoE configurations for different service types (e.g., streaming, MTSI, MBS, XR). Each configuration can be independently activated, modified, or paused, which improves adaptability to different services while managing complexity through modular, service-specific measurement sets

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements universal QoE measurement capabilities that can serve multiple service types through a common framework. The RAN node can handle multiple QoE configurations simultaneously with unified management procedures, achieving versatility across different services without proportionally increasing device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A radio access network (RAN); a core network (CN) or operations, administration, and management (OAM) node; and a user equipment (UE) can implement a method for managing Quality of Experience (QoE) reporting from the UE. The method includes: facilitating QoE reporting to a QE node for the UE; determining to perform a handover for the UE from a source node of the RAN to a target node of the RAN; and pausing the QoE reporting. The method may further providing information to identify a QoE configuration of multiple configurations. The information may include QoE configurations, reference identifiers, QoE configuration identifiers, and information about associations between the reference identifiers and the QoE configuration identifiers.
