Solution Overview
Problem
Existing communication quality prediction methods struggle to accurately estimate changes in communication quality using selected terminal information, leading to inadequate prediction of wireless network fluctuations.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If terminal information including position, posture, motion, control information, camera information, sensor information, and past communication information is collected and used to generate a communication quality model, then communication quality prediction capability is improved, but device complexity and data processing requirements increase significantly
Solution Approach 1:
The patent extracts only the essential blocking object detection function from the complex terminal information set. Instead of using all terminal information (position, posture, motion, control information, camera information, sensor information, and past communication information), the invention focuses specifically on image data from the camera to detect blocking objects, thereby reducing system complexity while maintaining prediction capability
Solution Approach 2:
The patent replaces the complex communication quality model generation approach with a simpler blocking object detection and prediction system. By using image processing and blocking object analysis instead of comprehensive terminal information processing, the system achieves communication quality prediction with reduced complexity
2Device complexity
If only selected terminal information is used for communication quality estimation, then device complexity is reduced, but communication quality prediction accuracy deteriorates
Solution Approach 1:
The patent introduces blocking objects as an intermediary element to predict communication quality. Instead of directly using complex terminal information or attempting to model communication quality from limited data, the system uses blocking objects detected from image data as a mediator to infer communication quality changes, achieving accurate prediction with simpler processing
Solution Approach 2:
The patent uses image data as a visual copy or representation of the physical environment between the moving body and base station. By analyzing this visual copy to detect blocking objects, the system can predict communication quality without needing to process actual complex terminal information, thereby maintaining accuracy while reducing complexity
