Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If MICO mode parameters are set to reduce terminal power consumption, then power consumption decreases, but service quality may deteriorate

Engineering Contradiction:
Improveterminal power consumptionVSAvoidservice quality
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent dynamically adjusts MICO mode parameters (such as periodic registration timer values, active time settings, and communication intervals) based on terminal behavior patterns and network conditions. By changing these parameters adaptively rather than using fixed values, the system optimizes the balance between power consumption and service quality for different scenarios.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements feedback mechanisms where the network analyzes terminal communication patterns, service types, and performance metrics to continuously refine MICO mode parameter settings. This feedback loop ensures that parameter adjustments maintain service quality while achieving power savings, preventing degradation by learning from actual system performance.

Inventive Principle:
Principle #23Feedback

2Use of energy by moving object

If MICO mode parameters are optimized for power saving, then power consumption decreases, but communication efficiency may be reduced

Engineering Contradiction:
Improveterminal power consumptionVSAvoidcommunication efficiency
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The patent introduces dynamic parameter adjustment where MICO mode settings are not static but adapt in real-time based on terminal activity patterns, service requirements, and network conditions. This dynamics allows the system to switch between more aggressive power-saving settings and performance-optimized settings as conditions change, maintaining communication efficiency while achieving power savings.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary analysis of terminal behavior patterns and service characteristics before finalizing MICO mode parameter settings. By predicting future communication needs based on historical data and current context, the system pre-optimizes parameters to prevent both power waste and communication inefficiency, ensuring parameters are set optimally before communication events occur.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If network analysis information is collected and processed, then MICO mode optimization improves, but network complexity increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a network data analytics function (NWDAF) as an intermediary component that专门 handles the complex tasks of collecting, processing, and analyzing terminal behavior data. This intermediary separates the optimization intelligence from the core MICO mode management, allowing the network to benefit from sophisticated analysis without significantly increasing the complexity of the MICO management logic itself. The NWDAF acts as a dedicated analytics layer that simplifies the overall system architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)
