Base Station Sleep Interval Adjustment for Power and Delay Trade-offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-real time data transmission methods in mobile networks face a challenge in balancing power-saving with reduced time delays, as exponential growth in sleep intervals leads to significant time delays, restricting transmission performance.
Innovation Solution
A base station dynamically adjusts the sleep interval based on the ratio of the sleep interval to the sleep cycle, data transmission efficiency, and packet delay status, using a processor to determine optimal sleep interval values and inform mobile apparatuses, thereby maintaining a balance between power-saving and short data transmission time delays.

Engineering Contradiction Analysis
1Loss of energy
If exponential growth in sleep intervals is used for non-real time data transmissions, then power-saving effect is improved, but time delay increases significantly
Solution Approach 1:
The patent implements dynamic adjustment of sleep interval lengths based on real-time network conditions and data transmission requirements. The base station monitors data arrival patterns and dynamically modifies the sleep interval duration, transitioning from fixed exponential intervals to adaptive intervals that respond to actual traffic conditions, thereby balancing power consumption with transmission delay
Solution Approach 2:
The patent changes the parameter of sleep interval length from a static exponential growth pattern to a dynamically adjustable parameter. By modifying the sleep interval duration based on data transmission efficiency metrics and network conditions, the system optimizes the trade-off between power saving and transmission delay, allowing flexible adaptation to varying data traffic patterns
2Device complexity
If fixed exponential sleep intervals are used, then device complexity is reduced, but adaptability to different data transmission conditions deteriorates
Solution Approach 1:
The patent introduces a feedback mechanism where the base station monitors data transmission efficiency, data arrival patterns, and network conditions, then uses this information to dynamically adjust sleep interval lengths. The system continuously receives feedback about actual transmission performance and modifies sleep intervals accordingly, enabling adaptation to varying data transmission conditions without requiring complex predetermined configurations
Solution Approach 2:
The sleep mechanism performs self-adjustment based on monitored network conditions and transmission patterns. The base station automatically modifies sleep interval parameters in response to observed data traffic characteristics, eliminating the need for manual configuration or complex external control systems while maintaining adaptability to different transmission scenarios
