Mobile Terminal Measurement Cycle Control for Link Status Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in reducing power consumption and network load during link status monitoring, as measurements are often performed unnecessarily in areas with good reception quality, leading to increased power usage and network load.
Innovation Solution
A mobile terminal determines its measurement cycle based on the reception quality of the radio signal from a base station, switching on or off measurements and adjusting their frequency based on whether the quality is above or below a predetermined threshold, thereby controlling the execution of link status measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurements are performed frequently to ensure accurate link status monitoring, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the measurement cycle adjustable rather than fixed. The mobile terminal dynamically changes the measurement cycle based on reception quality conditions - using shorter cycles when quality is poor and longer cycles when quality is good, thereby optimizing the balance between measurement accuracy and power consumption
Solution Approach 2:
The patent changes the measurement cycle parameter based on reception quality. When reception quality is below a threshold, the measurement cycle is set to a first (shorter) value for accurate monitoring. When reception quality is above the threshold, the cycle is set to a second (longer) value to reduce power consumption, thus adapting the system parameter to operational conditions
2Measurement precision
If measurements are performed frequently to ensure accurate link status monitoring, then measurement precision is improved, but network load increases
Solution Approach 1:
The system dynamically adjusts the measurement cycle based on reception quality conditions. In good reception areas, the extended measurement cycle reduces the frequency of measurements and subsequent report transmissions, thereby decreasing network signaling volume and load while maintaining adequate monitoring accuracy
Solution Approach 2:
The patent applies partial action by performing measurements at reduced frequency when reception quality is good. Since accurate link status monitoring is less critical in good reception conditions, the system performs fewer measurements and reports only when necessary, reducing network load while maintaining sufficient monitoring capability
3Use of energy by moving object
If the measurement cycle is extended to reduce power consumption, then power consumption is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent changes the measurement cycle parameter based on reception quality thresholds. When reception quality is below the threshold, the cycle is set to a first (shorter) value for accurate monitoring. When reception quality is above the threshold, the cycle is set to a second (longer) value to reduce power consumption, thus adapting the system parameter to operational conditions
Solution Approach 2:
The patent applies local quality by differentiating measurement behavior based on local reception quality conditions. In areas with poor reception, frequent measurements are performed to ensure accuracy. In areas with good reception, less frequent measurements are sufficient, allowing the system to optimize power consumption locally based on actual conditions

AI summary
A mobile station determines, in accordance with reception quality of a radio signal from a base station, a measurement cycle of a predetermined measurement on a link status and/or on/off of the predetermined measurement and controls execution of the predetermined measurement based on the determination.
