Abstract: Analyzing measurement results of a target system. The analysis is performed by receiving a first matrix including first measurement results of the target system; training a matrix decomposition model with the first matrix to obtain a third matrix of normal or stable measurement results and a fourth matrix of anomalous or unstable measurement results; receiving a second matrix including second measurement results of the target system, wherein the second measurement results are later measurement results compared to the first measurement results; selecting from the third matrix a subset that matches with the second matrix; subtracting the selected subset from the second matrix to obtain a fifth matrix; outputting the fifth matrix or information derived from the fifth matrix for the purpose of evaluating performance of the target system.

Abstract: A computer implemented method for analyzing operation of cells of a communications network is provided. The method includes: obtaining data comprising performance indicators data from a first cell and a group of reference cells for a selected time period; —identifying, for the first cell, first change point of a first performance indicator, calculating magnitude of the change of the first performance indicators at the first change point, and defining the calculated magnitude as a first magnitude; identifying, for the group of reference cells, a group of reference change points of the first performance indicator, calculating magnitudes of the changes of the group of reference change points, and defining the calculated magnitudes as a group of reference magnitudes; comparing the first magnitude to the group of reference magnitudes to determine the relevance of the change point of the first cell; and providing output indicating the first change point of the first cell in response to detecting that said change point is determined relevant, or otherwise, providing output indicating that no relevant change points are identified.

Abstract: A computer implemented method for evaluating effect of a change made in a communication network. The method is performed by comparing values of the performance indicator in a cell of interest before and after the change to obtain a first comparison result; comparing values of the performance indicator in a set of reference cells before and after the change to obtain a second comparison result; and evaluating the effect of the change made in the communication network based on difference between the first comparison result and the second comparison result.

Abstract: Analysis of operation of a communications network. The analysis is performed by obtaining (301) time series of performance data of a cell of the communications network: selecting (302) a change point in the time series: determining (303) a first linear regression model before the selected change point and a second linear regression model after the selected change point; determining (304) offset difference between the first linear regression model and the second linear regression model; and determining (306) anomaly

Abstract: A computer implemented method of cell overlap analysis of a communication network. The method includes determining coverage area of a first and a second cell of the communication network, wherein determination of the coverage area of a cell is based on user distribution in the respective cell; determining intersecting area as an area where the determined coverage area of the first cell and the determined coverage area of the second cell overlap; and determining a first impact value reflecting impact of the overlap on the first cell as a ratio of the determined intersecting area and the determined coverage area of the first cell.
