Network Element Performance Measurement Report Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-organizing networks (SON) in 3GPP systems face challenges in optimizing coverage and capacity due to the mixing of periodic and event-based measurement triggers for minimization of drive test data, leading to suboptimal performance measurements that are not useful for all use cases, and privacy issues with data correlation.
Innovation Solution
A method and apparatus for sending performance measurement job activation to collect minimization of drive test data, converting user equipment measurement reports into performance measurements, and transmitting these measurements to the manager, allowing for separate analysis of periodic and event-based measurements, thereby optimizing data collection and addressing privacy concerns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If minimization of drive test data is converted into performance measurements using both periodic and event-based triggers, then the coverage of measurement scenarios is improved, but the reliability and usability of the measurements for specific use cases deteriorates
Solution Approach 1:
The patent segments the mixed measurement data into separate periodic measurement results and event-based measurement results. The network element generates distinct performance measurement reports for each type, allowing the network manager to selectively use appropriate measurement types for specific use cases, thereby maintaining both broad scenario coverage and high reliability for individual applications.
2Loss of information
If all connected UEs are used for measurement collection to support downlink coverage map use case, then the completeness of coverage data is improved, but the complexity of data correlation and processing increases
Solution Approach 1:
The patent extracts and separates the data correlation function from the network element to the network manager. The network element simply collects and reports raw measurement data from multiple UEs, while the network manager performs the complex task of correlating data from different UEs to generate coverage maps, thereby reducing the complexity burden on individual network elements while maintaining complete coverage data.
3Measurement precision
If minimization of drive test data is collected and correlated at the network manager layer, then the accuracy of coverage optimization is improved, but the privacy issues with data correlation worsens
Solution Approach 1:
The patent introduces performance measurements as an intermediary that aggregates and anonymizes raw minimization of drive test data. Instead of correlating individual UE measurement data which raises privacy concerns, the system uses aggregated performance measurement results that preserve coverage optimization accuracy while eliminating privacy issues by removing individual user identification information.

AI summary
Various communication systems may benefit from methods, apparatuses, and systems for data collection. For example, wireless communication systems of the third generation partnership project (3GPP) may benefit from data collection in network management layer coverage and capacity optimization. For example, a method may include sending performance measurement job activation indicating that minimization of drive test data is to be collected (in an alternative, the job can be configured to indicate that non-MDT data is to be collected). The method may also include receiving performance measurements in response to the job activation.
