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.

Computer implemented method for controlling a communications network

A computer implemented method for analysing antenna directions in a communications network. The method includes at least obtaining network related data; calculating a characteristic user direction of a first cell of a first base station; calculating a difference between the characteristic user direction and the antenna azimuth direction of the first cell; and responsive to detecting that the calculated difference is greater than a pre-set threshold angle, indicating an anomaly in the first cell.

Method for analysing antenna directions in a communication network

A computer implemented method of antenna analysis for a base station site of a communication network. The base station site serves at least a cell operating according to a first network technology and a cell operating according to a second network technology. The method includes receiving, from the base station site, performance data related to the first network technology and performance data related to the second network technology; analyzing the received performance data to check if the performance data indicates an antenna related performance problem; and outputting an indication of an antenna problem responsive to detecting an antenna related performance problem both in the performance data related to the first network technology and the performance data related to the second network technology.

Antenna analysis in communication networks

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.

Antenna tilting

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.

Method for optimizing antenna directions in a communications network

A computer implemented method of monitoring a communication network. The method includes obtaining first information related to remote electrical tilt configurations deployed in the communication network; obtaining second information related to cell documentation; comparing the first and second information to identify mismatches between the first and second information, if any; and outputting an alarm concerning mismatches identified as a result of the comparison.

Network monitoring related to remote electrical tilt

A computer implemented method of handling threshold value of an antenna performance parameter of an antenna of a telecommunication network. A default antenna performance parameter threshold value of the antenna is obtained; a second antenna performance parameter threshold value for the antenna is determined based on the default antenna performance parameter threshold value and loss information related to the antenna, or based on gradually testing antenna performance parameter threshold values; and the second antenna performance parameter threshold value is taken into use for the antenna.
