Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices waste power due to frequent updates of servo base stations during the cell reselection process, as they often switch base stations based on slight changes in signal intensity, leading to unnecessary power consumption.
Innovation Solution
A wireless communication device with a signal detection unit, signal differential accumulation unit, and determination unit that periodically assesses signal intensity differences between servo and candidate base stations, only updating the servo base station group when the total signal intensity difference exceeds a predetermined threshold, thereby reducing unnecessary updates and conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the mobile phone updates the servo base station list frequently when signal intensity changes slightly, then the base station selection responds quickly to signal changes, but considerable power is wasted due to excessive updates
Solution Approach 1:
The patent implements a dynamic threshold mechanism where the threshold for base station selection is adjusted based on historical signal intensity data. When signal changes are minor and frequent, the threshold increases to prevent excessive updates. When signal changes are significant, the threshold decreases to allow faster response. This dynamic adjustment resolves the contradiction by making the system responsive to meaningful changes while filtering out noise.
Solution Approach 2:
The patent changes the parameter of threshold value dynamically based on signal characteristics. By modifying the threshold parameter according to signal intensity variations and update frequency, the system achieves both quick response to important signal changes and reduced power consumption by suppressing unnecessary updates caused by minor fluctuations.
2Adaptability or versatility
If the mobile phone uses a low threshold for updating servo base stations, then the system adapts quickly to signal changes, but unnecessary updates occur frequently causing power waste
Solution Approach 1:
The threshold is made dynamic rather than fixed. The system monitors signal intensity patterns and adjusts the threshold accordingly - using lower thresholds when signal changes indicate genuine improvement opportunities and higher thresholds when changes are likely to be noise. This maintains adaptability while reducing unnecessary updates.
Solution Approach 2:
The system incorporates feedback mechanisms where previous update outcomes and signal patterns are used to adjust future threshold settings. If recent updates resulted in minimal signal improvement, the threshold increases to prevent repeated unnecessary updates. This feedback loop maintains adaptability while conserving energy.
3Loss of energy
If the mobile phone implements strict criteria for base station updates, then power consumption is reduced, but the response to genuine signal improvements is delayed
Solution Approach 1:
The threshold dynamically adapts to signal conditions - becoming more stringent during periods of stable signals to save power, and becoming more permissive when significant signal changes occur to ensure quick response. This resolves the contradiction by making strictness context-dependent rather than absolute.
Solution Approach 2:
The system changes the threshold parameter based on signal characteristics and update history. When signal intensity shows sustained improvement trends, the effective threshold decreases to allow faster selection. When signals fluctuate without clear improvement, the threshold remains high to prevent unnecessary updates, thus balancing power savings with response speed.

AI summary
A wireless communication device and method includes selecting a group of neighboring base stations having a relatively stronger signal intensity among the neighboring base stations as servo base stations, and periodically detecting the signal intensities of the servo base stations and the candidate base station. Differences between the signal intensities of two selected neighboring base stations for each cycle of a continuous cycles are accumulated, where when the accumulated value exceeds a threshold value in a each cycle, the group of servo base stations are updated and weakest servo base stations with the strongest candidate base station in that cycle are replaced.
