A computer-implemented method for analyzing the operation of a cell in a communications network has been detailed in a filed patent (Publication Number: US20240007200A1). The method involves collecting data on signal level performance indicators from multiple cells, calculating characteristic values based on the collected data, determining differences between calculated values and actual measurements, and providing output information if discrepancies exceed a preset threshold. The analysis can be performed for various cell types, including GSM900, LTE800, LTE1800, LTE2100, LTE2600, and 5G, and for different signal level performance indicators such as RSRP, RSRQ, RSSI, SNR, SINR, RSCP, CQI, and TA indicators. The method also allows for identifying specific issues with antenna systems, radios, antennas, and antenna ports based on the detected discrepancies.

Furthermore, the patent includes provisions for analyzing operation at different frequency bands, antenna azimuth directions, and antenna port levels. The method can be conducted daily, weekly, monthly, or at other fixed intervals to ensure continuous monitoring and maintenance of the network. Additionally, the patent describes an apparatus and a computer program product that can execute the method by collecting data, calculating characteristic values, determining differences, and providing output information. The apparatus includes a processor and memory with computer program code, while the computer program product comprises non-transitory executable code for performing the analysis. Overall, the patent outlines a comprehensive approach to monitoring and identifying operational issues within a communications network, enhancing efficiency and performance.
