Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in effectively presenting location-specific and time-variant radio resource usage information in a shared spectrum environment, where a large amount of data needs to be visualized across different domains like time, location, and frequency, which becomes complex when presented on a static 2D medium.
Innovation Solution
A method and system that receive radio resource reservation data, allow users to select geographical areas and time periods of interest, divide the area into subareas, calculate utilization rates, and render these as a colored geographical map, enabling easy visualization and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If radio resource usage information is presented in detail across multiple domains (time, location, frequency), then information completeness is improved, but visualization complexity increases
Solution Approach 1:
The patent segments the geographical area into multiple cells and divides radio resource usage information into different dimensions (geographical, temporal, frequency). Each dimension is visualized separately using color-coded heat maps, allowing comprehensive information presentation without overwhelming complexity. The segmentation of space and information types enables manageable visualization of multi-domain data.
Solution Approach 2:
The patent transforms multi-dimensional radio resource usage data into a 2D visual representation by adding the spatial dimension through geographical mapping. Time and frequency information are encoded through color intensity and temporal slicing, converting abstract multi-dimensional data into intuitive spatial visualizations that can be displayed on standard 2D screens while preserving information completeness.
2Loss of information
If comprehensive radio resource information is displayed, then data coverage is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies local quality by allowing users to focus on specific geographical areas, time periods, or frequency bands of interest. The system provides both overview and detailed views, enabling users to drill down into specific regions or time windows for in-depth analysis while maintaining the ability to view comprehensive data at higher levels. This hierarchical approach maintains ease of operation by letting users control the level of detail displayed.
Solution Approach 2:
The patent uses color-coded heat maps to represent radio resource usage intensity across different dimensions. Color intensity visually encodes utilization rates, making it easy to identify high and low usage areas at a glance. This visual encoding transforms complex numerical data into intuitive color patterns, significantly improving ease of analysis while maintaining comprehensive data coverage.
3Measurement precision
If detailed radio resource reservation data is presented, then measurement precision is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The patent performs preliminary processing of radio resource reservation data by calculating utilization rates and organizing information by geographical cells, time periods, and frequency bands before visualization. This pre-processing aggregates and structures raw data into meaningful metrics that can be directly mapped to visual representations, reducing the complexity of detecting and measuring while preserving measurement precision.
Solution Approach 2:
The patent introduces intermediate visual representations (heat maps, color-coded regions) that mediate between detailed numerical data and human perception. These visual intermediaries translate precise measurement data into intuitive spatial patterns, making it easier to detect and analyze radio resource usage while maintaining the precision of the underlying measurements through appropriate color scaling and legends.
