Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DRX parameters are configured using real-time auxiliary information from terminals, then DRX parameter optimization is improved, but power consumption increases and data privacy security risks worsen
Solution Approach 1:
The base station performs preliminary actions by acquiring historical DRX transmission feature data from terminal equipment before configuring DRX parameters. The neural network model is trained in advance using this historical data, enabling the base station to predict service types and determine optimal DRX parameters without requiring real-time auxiliary information transmission from the terminal, thus reducing power consumption while maintaining optimization effectiveness
2Adaptability or versatility
If DRX parameters are configured using real-time auxiliary information from terminals, then DRX parameter optimization is improved, but data privacy security risks worsen
Solution Approach 1:
The invention extracts and utilizes only the necessary historical DRX transmission feature data from the terminal equipment to train the neural network model. By taking out only the essential features (such as traffic patterns, transmission timing) rather than requiring comprehensive real-time auxiliary information, the system achieves DRX parameter optimization while minimizing data privacy security risks associated with transmitting and processing sensitive terminal data
3Adaptability or versatility
If terminal equipment transmits auxiliary information to base station for DRX configuration, then DRX parameter optimization is improved, but signaling overhead increases
Solution Approach 1:
The invention extracts only the essential historical DRX transmission feature data needed for neural network model training, eliminating the need for terminals to transmit comprehensive auxiliary information. This selective extraction approach reduces signaling overhead while still providing sufficient data for the base station to accurately predict service types and optimize DRX parameters
4Use of energy by moving object
If DRX parameters are not optimized, then power consumption is reduced, but battery life decreases
Solution Approach 1:
The invention changes DRX parameters dynamically by predicting service types using a neural network model trained on historical transmission features. The base station adjusts DRX parameters (such as active time, sleep time, reactivation timing) based on predicted service characteristics, enabling the system to optimize the balance between power consumption and battery life by adapting parameters to actual transmission needs rather than using fixed or overly aggressive power saving settings
