UE Idle Mode Measurement Threshold Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face high power consumption in mobile devices due to excessive measurements during idle mode, which reduces battery duration and efficiency.
Innovation Solution
A power management method that adjusts idle mode measurement thresholds in user equipment (UE) to minimize unnecessary measurements, specifically for devices expected to remain stationary for extended periods, by configuring a 'stationary extra-long battery device configuration' to decrease power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If idle mode measurements are performed frequently to ensure network connectivity and signal quality, then measurement precision and network responsiveness are improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the measurement threshold adjustable based on device characteristics. The network can dynamically configure different threshold values for different UEs, allowing the measurement trigger condition to adapt to the device's power capabilities and mobility requirements, thus resolving the contradiction between measurement precision and power consumption
Solution Approach 2:
The patent applies local quality by providing differentiated measurement thresholds tailored to specific device types. Stationary devices with extra-long battery life receive higher thresholds (less frequent measurements), while mobile devices receive lower thresholds (more frequent measurements), optimizing the balance between measurement precision and power consumption for each local context
2Reliability
If idle mode measurements are performed frequently to maintain network awareness, then network responsiveness is improved, but battery duration decreases
Solution Approach 1:
The patent applies parameter changes by modifying the measurement threshold parameter based on device characteristics. By changing this critical parameter, the system achieves different measurement frequencies that balance network responsiveness requirements with battery conservation, allowing stationary devices to extend battery duration while maintaining adequate network awareness
3Loss of information
If measurement threshold is lowered to increase measurement frequency, then network awareness is improved, but power consumption efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by enabling the measurement threshold to be dynamically adjusted based on device characteristics and network conditions. This dynamic adjustment allows the system to optimize the balance between maintaining network awareness (avoiding information loss) and conserving energy, with different thresholds applied to different device types
