Adaptive QoE Measurement With UE And Network-Side Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current QoE measurements from User Equipment (UE) are limited to application layer and cannot measure network-side performance, leading to suboptimal network configuration and security risks due to unauthorized data collection.
Innovation Solution
Collecting Minimized Drive Test (MDT) measurements from the RAN node and QoE measurements from the UE, correlating them with device and base station configuration parameters to generate optimized network settings using an analysis server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoE measurements are collected only from the UE application layer, then the measurement process is simple and secure, but the measurement precision is insufficient as network-side performance cannot be measured
Solution Approach 1:
The patent combines MDT measurements from the RAN node with QoE measurements from the UE application layer into a unified measurement framework. The MDT configuration includes parameters such as measurement quantity, measurement filter, and reporting configuration, which are integrated with existing QoE measurement processes to enable comprehensive network-side and device-side performance assessment
Solution Approach 2:
The measurement system is segmented into distinct components: MDT measurements for network-side performance (throughput, latency, packet loss) and QoE measurements for application-layer performance. Each segment operates with its own configuration parameters and reporting mechanisms, allowing independent optimization while contributing to overall measurement precision
2Measurement precision
If comprehensive measurements are collected from both network node and UE, then the measurement precision improves, but security risks increase due to unauthorized data collection
Solution Approach 1:
The patent implements an authorization feedback mechanism where the UE explicitly provides authorization information to the RAN node before MDT measurements are collected. The RAN node receives and processes this authorization feedback, ensuring that data collection occurs only with user consent. This feedback loop maintains security while enabling comprehensive measurements
Solution Approach 2:
The patent introduces an intermediary authorization mechanism that mediates between the RAN node's measurement needs and the UE's security requirements. The authorization information acts as an intermediary credential that validates the RAN node's right to collect data, preventing unauthorized access while facilitating legitimate measurement activities
3Loss of information
If MDT and QoE measurements are collected and correlated, then the loss of information is reduced, but the device complexity increases due to configuration management
Solution Approach 1:
The patent employs a universal Trace ID that serves multiple functions: it identifies MDT measurement configurations, correlates QoE measurements, and links reporting instances across different measurement types. This single universal identifier simplifies the correlation process by providing a common reference point, reducing the complexity of managing multiple configuration parameters while ensuring complete data association
