Base Station Battery Level Configuration for Mobile Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, mobile stations face high power consumption when fully awake, which reduces battery life, as existing methods for minimizing power consumption are inadequate in managing power usage based on battery levels.
Innovation Solution
A system where a base station monitors and receives battery level feedback from mobile stations, using this information to configure operation parameters such as receiver schemes, error control schemes, and paging configurations to optimize power usage and extend battery life, by adjusting settings like reducing power-intensive components and increasing idle mode duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the mobile station operates in idle mode to minimize power consumption, then battery life is extended, but communication responsiveness deteriorates
Solution Approach 1:
The system dynamically adjusts the mobile station's operational state based on battery level. When battery level is high, the mobile station operates in connected mode with full functionality. When battery level drops below a threshold, the system transitions to idle mode with extended sleep periods, dynamically balancing power consumption and communication responsiveness based on real-time battery status.
Solution Approach 2:
The invention changes the operational parameters of the mobile station based on battery level. Specifically, it modifies the idle mode duration, paging cycle length, and wake-up frequency as battery level decreases. This parameter adjustment allows the system to extend battery life by increasing idle mode duration while maintaining acceptable communication responsiveness through adaptive parameter tuning.
2Loss of time
If the mobile station wakes up frequently to check for pages, then communication responsiveness is improved, but power consumption increases
Solution Approach 1:
The system implements periodic wake-up cycles where the mobile station alternates between sleep mode and active state. During idle mode, the mobile station sleeps for extended periods and wakes up at predetermined intervals to check for pages. This periodic action reduces average power consumption compared to continuous operation, while still maintaining communication responsiveness by ensuring the station wakes up regularly to check for incoming communications.
3Use of energy by moving object
If power-intensive components are reduced to conserve battery, then energy efficiency is improved, but communication quality deteriorates
Solution Approach 1:
The system applies different operational qualities to different components based on battery level. When battery level is high, all components operate at full quality. When battery level drops, the system selectively reduces power consumption in specific components (such as lowering transmit power, reducing receiver sensitivity, or simplening processing) while maintaining critical communication functions. This local quality adjustment conserves energy without completely sacrificing communication quality.
