Solution Overview

Problem

Current methods for detecting cell performance degradation in wireless communication systems have low accuracy in determining overall performance degradation, as they only detect issues for individual key performance indicators (KPI) items without integrating multiple factors.

Innovation Solution

A device and method utilizing AI modeling to analyze performance degradation by acquiring data from cells, applying it to a specific model with reference data, and determining performance degradation through data compression and decompression, allowing for the integration of multiple KPI items and feature grouping to identify degraded performance features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple KPI items are monitored individually using conventional methods, then each specific performance issue can be detected, but the overall performance degradation detection accuracy remains low

Engineering Contradiction:
Improveperformance degradation detection accuracyVSAvoidcomplexity of performance analysis system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple individual KPI detection results into a unified performance degradation assessment. By integrating data from multiple KPI items (throughput, latency, error rates, etc.) and applying machine learning models, the system merges separate measurements into a comprehensive evaluation that accurately identifies overall cell performance degradation while reducing false positives.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces machine learning models and data fusion mechanisms as intermediaries between individual KPI measurements and final performance degradation determination. These intermediaries process, correlate, and analyze multiple KPI data streams to produce an accurate assessment of overall cell performance, bridging the gap between individual metrics and holistic evaluation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If conventional rule-based methods are applied to each KPI item, then individual performance issues can be identified, but the overall cell performance assessment is inaccurate

Engineering Contradiction:
Improvecell performance assessment reliabilityVSAvoidtime for performance analysis
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-training machine learning models with historical KPI data and establishing baseline performance profiles before actual performance monitoring begins. This pre-processing enables the system to quickly and reliably assess current cell performance by comparing real-time data against pre-established patterns, reducing analysis time while maintaining high reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent incorporates feedback mechanisms where performance assessment results are continuously fed back into the machine learning models to refine and update performance profiles. This closed-loop approach improves assessment reliability over time as the system learns from accumulated data, while the automated nature of the feedback process minimizes additional time requirements.

Inventive Principle:
Principle #23Feedback
