Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If predictive machine learning models are deployed in mobile networks, then network performance and mobility efficiency are improved, but model validity and reliability cannot be guaranteed due to corruption or lack of experience in certain situations

Engineering Contradiction:
Improvenetwork performanceVSAvoidmodel validity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the mobile terminal evaluates the predictive model's predictions against actual network behavior. The terminal compares predicted handover targets with actual handover outcomes and network conditions, then reports evaluation results back to the network. This feedback loop enables continuous validation and refinement of model validity, ensuring reliability while maintaining productivity benefits.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The mobile terminal autonomously performs evaluation of the predictive model's validity by comparing predictions with actual network behavior. The terminal independently determines whether the model is working properly based on local measurements and observations, without requiring constant network intervention. This self-service approach ensures continuous reliability monitoring while maintaining network performance optimization.

Inventive Principle:
Principle #25Self-service

2Reliability

If predictive models are continuously evaluated and refined, then model reliability is improved, but signaling overhead and system complexity increase

Engineering Contradiction:
Improvemodel validityVSAvoidsignaling overhead
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent implements partial evaluation by the mobile terminal, where the terminal performs local validation of model predictions against actual network behavior. Instead of comprehensive continuous evaluation, the terminal selectively evaluates models based on specific conditions and triggers, reducing signaling overhead while maintaining sufficient reliability. The terminal reports only when evaluation results indicate model validity issues or when configured thresholds are exceeded.

Inventive Principle:
Principle #16Partial or excessive action

3Speed

If predictive models are downloaded to mobile terminals for local inference, then processing speed is improved, but device complexity and memory requirements increase

Engineering Contradiction:
Improveprediction speedVSAvoidterminal complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent segments the machine learning system into two parts: the predictive model is downloaded to the mobile terminal for fast local inference, while the model evaluation and validation functionality is distributed to the terminal. This segmentation allows speed improvement through local prediction while managing device complexity by offloading complex evaluation tasks to the network based on terminal reports.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The predictive model is downloaded to the mobile terminal in advance before it is needed for inference. This preliminary action enables fast local predictions without real-time network communication delays, improving speed. The model is prepared and stored on the terminal beforehand, reducing processing latency when predictions are required for handover decisions.

Inventive Principle:
Principle #10Preliminary action
