Solution Overview
Problem
Current wireless communication devices face challenges in determining the geographic accuracy of device locations used by applications, leading to resource wastage and privacy concerns, as the accuracy often exceeds the requirements of the application and is difficult to assess.
Innovation Solution
A data processing system that correlates device locations with applications to determine geographic accuracy metrics by analyzing statistical features such as location entropy, block entropy, and radius of gyration, categorizing accuracy as high, medium, or low, and aggregating these metrics for individual applications.

Engineering Contradiction Analysis
1Measurement precision
If GPS accuracy is used for all applications, then location accuracy is improved, but energy consumption increases
Solution Approach 1:
The system dynamically changes the accuracy parameter of location data based on application requirements. By analyzing application characteristics and location usage patterns, the system adjusts the precision level (GPS, network triangulation, or base-station centroid) to match actual needs, thereby reducing energy consumption while maintaining sufficient accuracy.
2Measurement precision
If high accuracy device locations are used, then measurement precision is improved, but resource consumption increases
Solution Approach 1:
The system applies partial action by providing only the necessary level of location accuracy rather than maximum accuracy for all applications. By matching location precision to actual application requirements, the system avoids excessive resource consumption associated with high-accuracy GPS while maintaining sufficient precision for each specific use case.
3Device complexity
If device location accuracy is not assessed, then system complexity is reduced, but loss of information increases
Solution Approach 1:
The system implements self-service by automatically assessing and tracking geographic accuracy metrics without requiring manual intervention. The network element autonomously analyzes location data, correlates it with application usage, and generates accuracy metrics, thereby providing valuable information while minimizing additional system complexity.
