Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated measures are used to monitor and optimize network operation, then network optimization efficiency is improved, but the complexity of detecting and correcting RET equipment linkages worsens due to missing or incorrect data
Solution Approach 1:
The system implements automated feedback mechanisms by continuously monitoring network operation data and comparing it against planned configurations. The computer automatically detects discrepancies in RET equipment linkages and triggers corrective actions, creating a closed-loop control system that improves detection capability while maintaining automation efficiency
Solution Approach 2:
The invention introduces an intermediary computer system that acts as a mediator between network operation data and optimization actions. This computer receives data from multiple sources, performs automated analysis to detect missing or incorrect RET linkages, and generates correction instructions, thereby simplifying the detection process while maintaining high optimization efficiency
2Measurement precision
If manual intervention is used to detect and correct RET equipment linkages, then detection accuracy is improved, but labor time and operational complexity worsen
Solution Approach 1:
The system implements self-service automation where the computer automatically performs data collection, analysis, and correction without human intervention. The automated process retrieves network operation data, compares it with planned configurations, identifies missing or incorrect RET equipment linkages, and generates correction instructions, thereby maintaining high detection accuracy while eliminating manual labor time
Solution Approach 2:
The invention replaces manual mechanical processes with automated computer-based systems. Instead of human operators manually checking RET equipment linkages, the system uses automated data retrieval, comparison algorithms, and analysis processes to detect and correct linkages, achieving both high accuracy and time efficiency through substitution of mechanical human labor with automated computational processes
3Ease of operation
If RET equipment is adjusted remotely without verification, then operational efficiency is improved, but network reliability worsens due to potential interference from incorrect linkages
Solution Approach 1:
The system performs preliminary verification actions before executing remote RET adjustments. The computer automatically checks network operation data against planned configurations to ensure correct RET equipment linkages are in place before allowing remote adjustments, thereby maintaining operational ease while preventing reliability issues caused by incorrect linkages
Solution Approach 2:
The invention implements preliminary anti-action by proactively detecting and correcting potential problems before they can cause network interference. The automated system continuously monitors for missing or incorrect RET linkages and prevents remote adjustments until proper linkages are confirmed, thereby protecting network reliability while maintaining ease of operation when conditions are correct

AI summary
A computer implemented method for controlling a communications network. The method comprises obtaining, from the network, cell identifiers, remote electrical tilt, RET, equipment identifiers, link data comprising information about links between cells and RET equipment, and network configuration data, and, from a data storage, network planning data; finding a first cell, if any, missing a link to a RET equipment; searching based on comparing the network configuration data and the network planning data to which RET equipment, if any, the first cell should be linked, and responsive to detecting that the first cell and a first RET equipment should be linked, forming a link between the first cell and the first RET equipment; updating the link data with information comprising the formed link, if any; and using the updated link data in network control operations.
