Solution Overview

Problem

Current techniques for estimating wireless subscriber performance generalize the experience across a serving cell, ignoring actual UE environments and external factors, leading to inaccurate resource allocation and network adjustments.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If generalization of subscriber experience for entire serving cell is used, then device complexity is reduced, but measurement precision deteriorates

Engineering Contradiction:
Improvemodel complexityVSAvoidsubscriber experience prediction accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent divides the serving cell into multiple geographic areas or zones, each with its own machine learning model. This segmentation allows the system to capture local environmental characteristics and external factors specific to each area, thereby improving prediction accuracy without requiring a single overly complex model to account for all variations across the entire cell.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements location-specific machine learning models that are trained on data from particular geographic areas within the serving cell. Each model learns the local patterns, environmental conditions, and external factors relevant to its specific area, enabling more accurate predictions of subscriber experience for UEs in that location rather than using a generalized cell-wide model.

Inventive Principle:
Principle #3Local quality

2Measurement precision

If location-specific machine learning models are implemented, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvesubscriber experience prediction accuracyVSAvoidmodel selection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a dynamic model selection mechanism that adapts to changing conditions. The system monitors various parameters such as UE location, environmental conditions, and model performance metrics, and dynamically selects or switches between different machine learning models based on current conditions. This dynamic approach allows the system to maintain high prediction accuracy while managing complexity by only activating or selecting models when and where they are needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system includes automated model selection and performance evaluation mechanisms that operate without manual intervention. The machine learning framework automatically evaluates multiple models, selects the most appropriate one for given conditions, and can even retrain or update models based on new data. This self-service capability reduces the operational complexity of managing multiple location-specific models while maintaining their predictive benefits.

Inventive Principle:
Principle #25Self-service
