Abstract: A computer implemented method of antenna tilt analysis for a cell of a communication network. The method is performed by collecting performance data from the cell, determining number of bad coverage samples based on the performance data, determining value for a handover overlap parameter based on the performance data, detecting that the number of bad coverage samples and the value of the handover overlap parameter fulfil predetermined criteria, and responsively outputting instructions to change antenna tilt in the cell.

Abstract: A method for a mobile network, which mobile network is formed of cells. The method includes determining a weight factor between two cells of the mobile network, which determination of the weight factor includes calculating a distance factor between the cells, calculating an angle factor between the cells, and calculating the weight factor between the cells with an exponential function of the distance factor and the angle factor. The weight factors between the cells may be used for determining network parameters of a mobile network.

Abstract: Disclosed is a system and a method for detecting anomaly in a radio access network (RAN). The method includes receiving quality parameters data for a wide communication network established by plurality of base stations associated with the RAN; defining a first radio fingerprint based on the quality parameters data for the wide communication network; monitoring, by one of the base stations installed in a geological area, quality parameters data for a local communication network; defining a second radio fingerprint based on the quality parameters data for the local communication network; comparing the first radio fingerprint and the second radio fingerprint to determine variation in the quality parameters data therebetween; and generating an alert signal indicative of presence of a possible fake base station in the geological area based on the determined variation in the quality parameters data.

Abstract: A computer implemented method for uplink power control in a mobile network. The method is performed by obtaining (301) signal to interference and noise ratio, SINR, of a first cell of the mobile network; comparing (302) the SINR to current uplink power parameter of the first cell; determining (303) a new value for the uplink power parameter based on the comparison so that, if the SINR is higher than the current uplink power parameter, the current uplink power parameter is increased to obtain the new value for the uplink power parameter, and if the SINR is lower than the current uplink power parameter, the current uplink power parameter is decreased to obtain the new value for the uplink power parameter; and providing (304) the determined new value of the uplink power parameter for use in uplink power control of the first cell.

Abstract: Analyzing measurement results of a target system. Measurement results are obtained (401). The measurement results include multiple data entries, and each data entry includes multiple data values on a lowest hierarchy level and hierarchy information defining with which entities the entry is related to on different hierarchy levels. An aggregated anomaly score is determined (402) for each data entry. Data entries, wherein the aggregated anomaly score fulfils predefined criteria, are chosen for further analysis. Hierarchical clustering is performed (404) on the chosen entries based on dissimilarity of the chosen entries to combine at least some of the chosen entries together; and the hierarchically clustered entries are used (405) to identify one or more anomalous entities on hierarchy levels above the lowest hierarchy level.

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.

Abstract: A computer implemented method for energy savings management for cells of a sector or a base station of a communication network. The sector or base station has co-located cells that operate on different frequency bands. The method is performed by obtaining a default energy savings plan that calls for fully shutting down at least one of the cells for a first time period and provides a first amount of energy savings; evaluating energy savings achievable by using partial shutdown in cells and determining a second time period of partial shutdown that is needed for achieving the first amount of energy savings; obtaining a third time period that is usable for energy savings actions; and choosing to use partial shutdown in the cells, if the second time period is shorter than the third time period, and else choosing to use the default energy saving plan.
