Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If C-DRX technology is continuously applied to save battery, then battery consumption is reduced, but data transmission delay increases
Solution Approach 1:
The patent applies dynamics by making the C-DRX configuration changeable based on real-time application characteristics. The system dynamically adjusts whether to use C-DRX or not, depending on the detected application type and its delay sensitivity, rather than using a fixed configuration. This allows optimization between battery saving and low latency requirements.
Solution Approach 2:
The patent changes the operational parameter (C-DRX enabled/disabled state) based on application characteristics. By detecting whether an application is delay-sensitive and adjusting the C-DRX parameter accordingly, the system optimizes the trade-off between energy consumption and transmission delay for different use cases.
2Use of energy by moving object
If C-DRX technology is applied for battery saving, then energy efficiency is improved, but communication responsiveness deteriorates
Solution Approach 1:
The system dynamically adapts the C-DRX configuration based on the detected application's communication needs. When delay-sensitive applications are detected, the system disables C-DRX to maintain responsiveness. When non-delay-sensitive applications are detected, the system enables C-DRX to optimize energy efficiency, thus dynamically balancing productivity and energy consumption.
Solution Approach 2:
The patent implements feedback by detecting application characteristics and using this information to adjust C-DRX configuration. The system continuously monitors application behavior and adjusts the communication mode accordingly, creating a closed-loop control that optimizes both energy efficiency and responsiveness based on actual usage patterns.
3Device complexity
If fixed C-DRX configuration is used, then implementation complexity is reduced, but adaptability to different applications deteriorates
Solution Approach 1:
The system performs self-service by automatically detecting application characteristics and autonomously determining the appropriate C-DRX configuration without requiring manual user input or complex network-side control. The terminal itself analyzes application behavior and adjusts its communication mode, simplifying the overall system architecture while improving adaptability.
Solution Approach 2:
The patent changes the operational parameter (C-DRX enabled/disabled state) based on application characteristics. By detecting whether an application is delay-sensitive and adjusting the C-DRX parameter accordingly, the system optimizes the trade-off between battery saving and low latency requirements for different use cases.
Data Source
AI summary
A method for dynamically applying a battery saving technology by a terminal is disclosed. The method comprises transmitting a first message requesting an activation of a battery saving technology dynamic service to an authentication server, receiving a second message being a response to the first message from the authentication server, transmitting and receiving data with a base station in a battery saving technology deactivated state, when response information included in the second message comprises authentication success, and at least one application included in the second message is running, and maintaining a battery saving technology activated state when the application included in the second message is not running.
