QoE Measurement Handling During Wireless Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, during handover events, Quality of Experience (QoE) measurement reports are often fragmented and incomplete due to a lack of clear support from target radio network nodes, leading to resource wastage and incomplete data collection.
Innovation Solution
Incorporating explicit indications in handover messages regarding QoE measurement reporting support and measurement area status, allowing wireless devices to determine whether to continue or initiate QoE measurements based on the target node's capabilities and location within the measurement area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoE measurement reports are sent to target radio network nodes that do not support the feature, then measurement data collection is attempted, but network resources are wasted and the reports become fragmented and incomplete
Solution Approach 1:
The target radio network node includes a QoE measurement reporting support indication in the handover command message before the wireless device sends measurement reports. This preliminary indication allows the device to know in advance whether reporting is supported, preventing wasted resource consumption on unsupported nodes and ensuring complete reports are only sent when appropriate.
2Loss of energy
If QoE measurements are stopped during handover to avoid sending reports to unsupported nodes, then resource wastage is prevented, but measurement continuity is broken and reports become fragmented
Solution Approach 1:
The target radio network node provides feedback through the QoE measurement reporting support indication in the handover command. This feedback mechanism allows the wireless device to make informed decisions about continuing or pausing measurements based on the target node's capabilities, ensuring both resource efficiency and measurement continuity when supported.
3Productivity
If the RAN stops measurements when UE moves outside measurement area, then resource efficiency is improved, but complete session measurement is lost during handover
Solution Approach 1:
The system performs preliminary assessment of the target node's QoE measurement support capability before the UE leaves the measurement area. By including the support indication in the handover command, the system determines in advance whether measurements should continue, allowing complete session measurement while maintaining resource efficiency through informed decision-making.

AI summary
Methods and related wireless device and radio network node, which enable the handling of Quality of Experience, QoE, measurements during handover, are described. In some aspects, the wireless device may determine whether to report QoE measurements and whether to start new QoE measurements, in a cell served by a target radio network node, based, at least in part, on the presence or absence of QoE-measurement related indications in the handover command message received from the target radio network node.
