Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated measures are implemented to monitor and optimize network operation, then network optimization efficiency is improved, but system complexity increases
Solution Approach 1:
The system performs self-verification by automatically comparing network configuration data with planning data to identify missing RET equipment links. The automation engine independently detects discrepancies and triggers corrective actions without requiring manual intervention, enabling the network optimization system to self-manage RET equipment linking status.
Solution Approach 2:
The system establishes a feedback loop where the automation engine continuously monitors RET equipment links, compares actual configuration against planned configuration, and triggers corrective actions when discrepancies are detected. This closed-loop feedback mechanism ensures automated optimization while maintaining data accuracy through iterative verification and correction.
2Measurement precision
If manual verification of RET equipment links is performed, then accuracy of link data is improved, but time consumption increases
Solution Approach 1:
The system replaces manual mechanical verification processes with automated electronic data comparison. The automation engine electronically retrieves network configuration data and planning data, automatically compares them using algorithmic logic, and identifies discrepancies without human intervention. This substitution of manual mechanical verification with automated electronic processing maintains high accuracy while dramatically reducing time consumption.
Solution Approach 2:
The system creates and compares data copies of network configuration information and planning information to verify RET equipment links. By working with copied data rather than directly manipulating live network configurations, the system can perform comprehensive accuracy verification without time-consuming manual field checks, as the comparison can be executed rapidly through automated data processing.
3Measurement precision
If comprehensive data comparison is performed to identify missing links, then detection precision is improved, but computational load increases
Solution Approach 1:
The system extracts and compares only the specific critical data elements necessary for verifying RET equipment links - namely, cell identifiers, RET equipment identifiers, and link relationship data. By extracting and comparing only these essential elements rather than performing comprehensive analysis of all network parameters, the system achieves high detection precision for link accuracy while minimizing unnecessary computational load and energy consumption.

AI summary
A computer implemented method for controlling a communications network. The method includes 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.
