Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single machine learning model is used for all network slices, then the device complexity is reduced, but the measurement precision and reliability of network analytics deteriorate

Engineering Contradiction:
Improvemodel management complexityVSAvoidnetwork analytics precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent divides the monolithic machine learning model into multiple specialized models, with each model trained and optimized for a specific network slice or network side target. This segmentation allows each model to focus on the specific characteristics and requirements of its target slice, thereby improving measurement precision while managing complexity through modular architecture where models are independently trained and can be selectively deployed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by training different machine learning models with different characteristics for different network slices. Each model is optimized for the specific analytics needs of its target slice, such as different feature sets, loss functions, or data processing approaches, allowing each local region (network slice) to receive tailored analytics quality appropriate to its specific requirements.

Inventive Principle:
Principle #3Local quality

2Measurement precision

If multiple machine learning models are trained for different network slices, then the network analytics precision improves, but the device complexity and model management overhead increase

Engineering Contradiction:
Improvenetwork analytics precisionVSAvoidmodel management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a universal machine learning model management system that can handle multiple specialized models. The system includes a centralized management component that can train, deploy, monitor, and update various models for different network slices using common infrastructure and procedures. This multi-functional approach allows the system to manage model diversity without proportionally increasing complexity, as the same management framework serves all models.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes parameter changes in the model selection and training processes to adapt to different network slice requirements. The system can adjust model parameters such as training data scope, feature engineering approaches, performance metrics, and update frequencies based on the specific needs of each network slice, allowing precise analytics while managing complexity through parameterized configuration rather than structural complexity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If dedicated machine learning models are provided for specific network slices, then the reliability of network analytics improves, but the productivity of model training and deployment decreases

Engineering Contradiction:

Solution Approach 1:

The patent implements preliminary action by pre-training specialized machine learning models for different network slices before they are needed in production. The system can prepare models in advance using historical data and simulation environments, then deploy them rapidly when required. This allows the system to maintain high reliability through specialized models while improving productivity by avoiding time-consuming on-demand training and enabling parallel preparation of multiple models simultaneously.

Inventive Principle:
Principle #10Preliminary action
