DRX Parameter Adjustment for Mobile Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent monitoring of downlink channels by mobile devices to receive notification messages from numerous applications leads to high power consumption, potentially causing low battery issues and reduced standby time, especially when users fail to recharge promptly.
Innovation Solution
Implementing a power saving trigger mechanism that negotiates with a base station to adjust DRX-related parameters, such as prolonging the DRX cycle, reducing the frequency and duration of downlink channel monitoring, thereby conserving power and extending standby time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal monitors the downlink channel at a fixed frequency to receive notification messages, then the notification messages can be received timely, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the DRX parameters adjustable rather than fixed. The terminal can dynamically modify DRX cycle length, monitoring frequency, and other parameters based on battery status, service type, and network conditions. This allows the system to adapt between aggressive monitoring (for reliability) and conservative monitoring (for power saving) depending on current conditions.
Solution Approach 2:
The patent directly applies parameter changes by modifying DRX-related parameters such as DRX cycle length, monitoring frequency, and threshold values. When battery level drops below a threshold, the system changes these parameters to reduce monitoring frequency, thereby reducing power consumption while maintaining acceptable notification reception performance.
2Use of energy by moving object
If the DRX cycle is prolonged to reduce power consumption, then the standby time increases, but the notification message reception may be delayed
Solution Approach 1:
The system dynamically adjusts the DRX cycle length based on current conditions. Rather than using a fixed long DRX cycle that would cause delays, the terminal can shorten the cycle when notifications are expected or when power status allows, and extend it when power is critical and traffic is low. This dynamic adjustment balances power saving with timely reception.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal monitors both battery status and network conditions, then uses this feedback to adjust DRX parameters. If notifications are missed or power drops further, the system can respond by adjusting parameters to prevent further delays, creating a closed-loop control that balances power consumption and reception timeliness.
