Linked Radio-Layer and Application-Layer Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in coordinating and analyzing Quality of Experience (QoE) measurements and Radio Resource Control (RRC) signaling, leading to independent collection and reporting of application-layer and radio-layer measurements, which hinders accurate network optimization and user experience assessment.
Innovation Solution
Implementing methods for user equipment (UE) to perform concurrent radio-layer and application-layer measurements, with linked configurations and control indications, allowing for synchronized data collection and reporting to improve measurement coordination and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If application-layer and radio-layer measurements are collected and reported independently, then each measurement type can be optimized separately, but accurate correlation and analysis between the two measurement types becomes difficult
Solution Approach 1:
The patent combines application-layer QoE measurements and radio-layer MDT measurements into a unified measurement framework. The UE performs both measurement types concurrently and reports them together in a single measurement report message to the network, enabling accurate correlation between application performance and radio conditions while simplifying the measurement coordination mechanism.
2Measurement precision
If measurements are performed concurrently with linking configurations, then measurement correlation accuracy improves, but configuration and control complexity increases
Solution Approach 1:
The network configures the UE with linked measurement configurations in advance before measurements begin. The configuration includes parameters that establish the relationship between QoE and MDT measurements, such as common measurement identifiers and timing relationships. This preliminary configuration enables automated concurrent measurement execution without real-time coordination complexity.
Solution Approach 2:
The patent creates a universal measurement configuration framework that simultaneously controls both application-layer QoE measurements and radio-layer MDT measurements through a single configuration structure. This multi-functional configuration approach allows one set of configuration parameters to govern multiple measurement types, reducing overall configuration complexity while maintaining measurement synchronization.
3Productivity
If independent measurement reporting is used, then reporting simplicity is maintained, but network optimization effectiveness decreases due to lack of coordinated analysis
Solution Approach 1:
The patent merges QoE measurement results and MDT measurement results into a single measurement report message that is transmitted from the UE to the network. This combined reporting structure includes both application-layer performance data and radio-layer conditions data, enabling the network to perform coordinated analysis and optimization based on the correlated measurements while maintaining a simple single-report transmission mechanism.

AI summary
Embodiments include methods for a user equipment (UE) to perform radio-layer and application-layer measurements in a radio access network (RAN). Such methods include receiving the following from a RAN node: a first configuration of radio-layer measurements to be performed by the UE, a second configuration of application-layer measurements to be performed by the UE, and an indication that the radio-layer measurements and the application-layer measurements should be linked. Such methods include performing application-layer measurements related to one or more applications based on the second configuration, and performing radio-layer measurements based on the first configuration. At least a portion of the radio-layer measurements are performed concurrently with at least a portion of the application-layer measurements. Other embodiments include complementary methods for RAN nodes and network nodes or functions outside the RAN. Other embodiments include corresponding apparatus configured to perform these methods.
