Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional drive test methods using SIM-equipped mobile phones are used to evaluate mobile network performance, then network coverage and signal quality can be measured, but the process is inefficient and costly
Solution Approach 1:
User equipment automatically performs network performance measurements and reports results to the server without requiring manual drive test operations. The UE self-measures signal parameters (RSRP, RSRQ, SINR) and self-reports them via measurement reports, eliminating the need for specialized test equipment and operators.
Solution Approach 2:
The patent replaces manual mechanical drive test methods with automated electronic measurement and reporting systems. Instead of physical drive tests with specialized equipment, the system uses UE-based electronic measurements combined with server-side processing and satellite positioning for automated network evaluation.
2Measurement precision
If satellite positioning is used to obtain location information for network performance evaluation, then positioning accuracy is improved, but the system complexity increases
Solution Approach 1:
The patent combines satellite positioning with cellular network measurement in a unified system. The server integrates location data from satellite systems with network performance data from measurement reports, creating a comprehensive evaluation system that leverages existing infrastructure from both satellite and cellular domains.
Solution Approach 2:
The server performs multiple functions: collecting measurement reports from UEs, obtaining satellite positioning data, calibrating location information, and evaluating network performance. This multi-functional approach consolidates what could be separate systems into a single unified platform, managing complexity through integration.
3Ease of operation
If location information from measurement reports is used directly without calibration, then the process is simple, but positioning accuracy is insufficient
Solution Approach 1:
The server receives measurement reports containing location information, compares these with independently obtained satellite positioning data, and uses the satellite data as feedback to calibrate and correct the measurement report locations. This feedback loop improves accuracy while maintaining operational simplicity through automated calibration processes.
