Solution Overview

Problem

Existing QoE measurement frameworks fail to efficiently utilize network resources by storing QoE configuration and measurement data during idle states, leading to incomplete or delayed reporting of QoE metrics.

Innovation Solution

The proposed method involves storing QoE configuration and measurement data for UE in idle states, allowing for QoE and RVQoE measurements to be performed and reported upon transitioning back to connected states, with network nodes managing and transmitting data through signaling protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If QoE configuration is not stored during idle states, then network resources are saved, but QoE measurement completeness and timeliness deteriorate

Engineering Contradiction:
Improvenetwork resource usageVSAvoidQoE measurement completeness
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The network node stores QoE configuration information in the UE before the UE transitions to idle state. This preliminary action ensures that the UE has the necessary configuration data available when it wakes up, enabling immediate QoE measurement reporting without waiting for network re-provisioning, thus maintaining measurement completeness while minimizing network resource usage during idle periods

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If QoE measurements are performed during idle states without storing configuration, then measurement timing is delayed, but device complexity is reduced

Engineering Contradiction:
ImproveQoE reporting delayVSAvoidconfiguration management complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The network node provides QoE configuration information to the UE before the UE enters idle state. This allows the UE to perform QoE measurements immediately upon waking up and transitioning back to connected state, eliminating reporting delays. The configuration is stored in the UE's memory, avoiding the need for complex real-time configuration management during idle transitions

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If QoE configuration is stored in UE during idle states, then measurement timeliness is improved, but UE memory usage increases

Engineering Contradiction:
ImproveQoE reporting timelinessVSAvoidUE memory storage
Core Design Contradiction:
Loss of timeVSQuantity of substance

Solution Approach 1:

The patent extracts and stores only the essential QoE configuration information (such as measurement parameters, reporting criteria, and identification data) in the UE during idle state, rather than storing complete measurement datasets. This selective extraction approach enables timely QoE reporting when the UE reconnects while minimizing the memory storage burden on the UE device

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Systems and methods are disclosed that relate to storing of Quality of Experience (QoE) information or QoE configuration of a User Equipment (UE) while the UE is in an idle state. In some embodiments, QoE information or QoE configuration of a UE is stored by a network node while the UE is in the idle state and such stored information is utilized upon the UE transitioning back to the connected state. In some other embodiments, QoE information or QoE configuration of a UE is stored by the UE on behalf of the network while the UE is in the idle state and such stored information is utilized upon the UE transitioning back to the connected state. In some embodiments, QoE information or QoE configuration of a UE is stored by a first radio network node while the UE is in the idle state and such stored information is utilized upon the UE transitioning back to the connected state. Associated embodiments of core network nodes, radio network nodes and UEs and corresponding embodiments of methods of operation thereof are disclosed herein.
