Abstract: A computer implemented method for optimizing directions of antennas of a base station of a communications network is provided. The method includes receiving antenna sector configuration data with sector information of each antenna and an azimuth angle of a main antenna direction of each antenna; receiving performance indicators of multiple subsectors of each antenna sector; calculating a cost function value indicating inter-sector impact between neighboring subsectors of adjacent sectors based on the performance indicators for the current antenna configuration and for at least one other possible antenna configuration; and identifying an antenna configuration yielding minimum cost function value of the calculated values as an optimized antenna configuration.

Abstract: A computer implemented method for analyzing operation of a cell of a communications network includes collecting data with measurement samples of signal level performance indicators from multiple cells of the communications network; calculating a characteristic value for a signal level performance indicator for a first cell type based on the collected data, wherein a part of the best measurement samples of the signal level performance indicator of the first cell type are taken into account in the calculation of the characteristic value; calculating a difference between the calculated characteristic value and a measurement sample of signal level performance indicator of a first cell of the first cell type; and providing output information indicating that an antenna system of the first cell is operating incorrectly in response to detecting that the calculated difference is greater than a preset threshold.
