QoE Measurement Timing for Mobility Handover Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QoE measurement systems in cellular communications systems are not effectively configured to continue measurements during mobility events, leading to potential loss of data due to overwriting configurations.
Innovation Solution
Implementing a QoE measurement configuration with an associated measurement duration timer that continues measurements during mobility events, allowing for controlled and consistent data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If QoE measurement configuration is maintained during mobility events, then measurement continuity is improved, but configuration overwriting and data loss occur
Solution Approach 1:
The patent applies preliminary action by introducing a measurement duration timer that is started before the mobility event occurs. This timer pre-defines the measurement window, allowing the system to proactively manage the measurement lifecycle rather than reactively handling configuration overwriting issues during handover. The timer ensures that measurements are collected for the intended duration and automatically stopped before configuration overwriting can occur.
Solution Approach 2:
The patent implements feedback through the measurement duration timer mechanism that provides continuous time information to the QoE measurement process. The timer feedback allows the system to track measurement progress and automatically terminate measurements when the configured duration is reached, preventing configuration overwriting during mobility events while ensuring complete data collection for the intended measurement period.
2Duration of action of stationary object
If measurement duration timer is used to manage QoE measurements, then measurement continuity during mobility is improved, but system complexity increases
Solution Approach 1:
The measurement duration timer operates as a self-service mechanism that automatically manages the QoE measurement lifecycle without requiring complex external control logic. The timer self-starts when measurements begin, self-tracks the measurement duration, and self-terminates measurements when the configured time elapses, even during mobility events. This self-service approach simplifies the overall system architecture by replacing complex management logic with a straightforward timing mechanism.

AI summary
Systems and methods are disclosed herein that relate to Quality of Experience (QoE) measurement configuration and reporting in a cellular communications system during mobility. In one embodiment, a method performed by a User Equipment (UE) comprises receiving a QoE measurement configuration and a measurement duration time associated to the QoE measurement configuration, starting to perform QoE measurements in accordance with the QoE measurement configuration, starting a measurement duration timer upon starting to perform the QoE measurements, the measurement duration timer being initialized to the measurement duration time associated to the QoE measurement configuration, and continuing to perform the QoE measurements while the measurement duration timer is running. Embodiments related to the method of operation of a RAN node are also disclosed.
