Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio parameter optimization techniques face challenges in accurately determining optimal radio parameters due to varying radio quality reports from moving radio terminals, leading to increased processing loads and difficulty in optimizing parameters for specific movement states, such as in-store or station communications, and handover scenarios.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement information from all radio terminals is collected and processed, then comprehensive data for optimization is obtained, but processing load increases
Solution Approach 1:
The patent extracts and processes only the measurement information from radio terminals that are stationary or within a predetermined movement range. By filtering out measurement data from terminals with excessive movement, the system reduces processing load while maintaining optimization accuracy for relevant areas.
Solution Approach 2:
The patent applies different processing approaches based on terminal movement characteristics. Stationary terminals receive full processing for optimization, while moving terminals beyond the predetermined range have their measurements excluded or given lower weight, creating a localized quality approach tailored to each terminal's movement state.
2Quantity of substance
If measurement information from moving radio terminals is processed, then more data points are available, but measurement accuracy deteriorates due to movement variations
Solution Approach 1:
The patent changes the selection criterion parameter from simply accepting all measurements to filtering based on terminal movement range. By setting a predetermined movement range threshold, the system maintains measurement precision by excluding data from terminals that have moved excessively, while still processing measurements from terminals within the acceptable range.
3Ease of operation
If radio parameters are optimized without considering terminal movement, then processing is simplified, but optimization effectiveness decreases for specific scenarios
Solution Approach 1:
The patent introduces dynamic adjustment of processing based on terminal movement state. The system automatically adapts which measurement information to process by evaluating terminal movement ranges, making the optimization process responsive to actual network conditions while maintaining operational simplicity through automated decision-making.
