Wi-Fi Module Listen Interval Control to Reduce Unnecessary Wake-Ups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi module management in terminal devices leads to unnecessary power consumption due to frequent wake-ups based on a fixed listen interval, regardless of data transmission frequency.
Innovation Solution
Adjust the listen interval of Wi-Fi modules based on the data transmission and reception volume, inversely proportional to the volume, to reduce unnecessary wake-ups and conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Wi-Fi module uses a fixed listen interval to wake up regardless of data transmission frequency, then the Wi-Fi module can reliably check for data, but unnecessary power consumption increases
Solution Approach 1:
The patent applies dynamics by making the listen interval adjustable rather than fixed. The system dynamically modifies the listen interval based on actual data transmission characteristics, transitioning from a static wake-up schedule to a adaptive one that responds to network conditions and data activity levels.
Solution Approach 2:
The patent changes the parameter of listen interval based on data transmission volume and frequency. By monitoring actual data communication patterns and adjusting the wake-up interval parameter accordingly, the system optimizes the balance between reliable data detection and power consumption reduction.
2Reliability
If the Wi-Fi module wakes up frequently to check for data, then data transmission reliability is maintained, but battery power consumption increases
Solution Approach 1:
The patent implements feedback by monitoring actual data transmission volume and using this information to adjust the listen interval. The system continuously measures data communication characteristics and modifies wake-up frequency accordingly, creating a closed-loop control system that optimizes power consumption while maintaining transmission reliability.
Solution Approach 2:
The patent applies periodic action by establishing regular wake-up cycles adjusted to actual needs. Instead of continuous monitoring, the system uses optimized periodic wake-ups based on observed data patterns, reducing unnecessary power consumption while ensuring data is checked at appropriate intervals.
3Use of energy by moving object
If the listen interval is extended to reduce wake-ups, then power consumption decreases, but the risk of missed data transmission increases
Solution Approach 1:
The system dynamically adjusts the listen interval based on real-time data transmission observations. When data activity is low, the interval is extended to save power; when data activity increases, the interval is reduced to maintain reliability, creating an adaptive balance between energy efficiency and communication reliability.
Solution Approach 2:
The system performs preliminary monitoring of data transmission characteristics and uses this information to proactively adjust the listen interval before power consumption becomes excessive. By anticipating data needs based on observed patterns, the system prevents both excessive wake-ups and potential data loss.

AI summary
Embodiments of the present disclosure provide a terminal device control method and a terminal device. The method includes: obtaining a target data transmission and/or reception volume of a target Wi-Fi module in the terminal device; determining a target listen interval of the target Wi-Fi module that corresponds to the target data transmission and/or reception volume, where a listen interval of the target Wi-Fi module is inversely proportional to the data transmission and/or reception volume; adjusting the listen interval of the target Wi-Fi module to the target listen interval; and waking up the target Wi-Fi module according to the target listen interval in a case that the target Wi-Fi module is in a sleep state.
