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: A computer implemented method for adjusting a tilt angle of an antenna of a base station of a communications network is provided. The method includes at least: obtaining data related to the base station having user equipment distance data and antenna data; calculating a main radiation beam reach for a first antenna from the antenna data; calculating a characteristic user equipment distance from the user equipment distance data; comparing the calculated main radiation beam reach and the calculated characteristic user equipment distance; and responsive to detecting that the characteristic user equipment distance is greater than the main radiation beam reach, calculating a new antenna tilt angle for the first antenna.

Abstract: A computer-implemented method for automatically detecting a fraud call. A call request is received from a caller device to initiate a voice call with a called device at a local Public Land Mobile Network (PLMN). The call request is identified originating from a foreign Public Land Mobile Network (PLMN). In response to detecting that a caller ID of the caller device is associated to a local Public Land Mobile Network (PLMN), current location information is requested from a database of the local Public Land Mobile Network (PLMN). If the location information indicates the caller device is attached to the foreign Public Land Mobile Network (PLMN), determining the call request as authentic; and if the location information indicates the caller device is attached to the local Public Land Mobile Network (PLMN), determining the call request as fraud.

Abstract: Disclosed herein is a computer-implemented method for detecting activity in an audio stream. In at least one embodiment, the method includes: obtaining an audio stream; and detecting activity in the audio stream based on detection criteria, where the detection criteria include at least two of: an audio amplitude threshold, where sections of the audio stream with an audio amplitude less than the audio amplitude threshold are classified as inactive; a detection delay defining a time interval of the audio stream during which activity in the audio stream is ignored; a minimum activity duration defining a minimum duration for an active section in the audio stream; and/or a maximum inactivity duration defining a maximum duration of inactivity in the audio stream.

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: Example embodiments may relate to detection of overshooting cells in a radio network. A computer-implemented method may comprise: communicating data traffic via a first cell of a first access node of a communication network, wherein a sector of the first access node comprises the first cell and a second cell of the first access node; restricting amount of data traffic communicated via the first cell; and determining that a third cell of a second access node is overshooting, in response to determining, after restricting the amount of data traffic communicated via the first cell, that at least part of the data traffic is communicated via the third cell and not via the second cell.

Abstract: A method of improving fault tolerance of a network. The network includes a plurality of relay nodes, internet access node and plurality of customer nodes. The method includes identifying first set of relay nodes connecting one of customer nodes to internet access node, selecting a first relay node from first set of relay nodes, to be simulated as a first faulty node in the network, detecting, based on the simulation, number of customer nodes without at least one corresponding network path connecting to the internet access node due to the selection of the first relay node as the first faulty node, determining impact score of the first relay node based on the detected number of customer nodes without at least one corresponding network path connecting to the internet access node, and triggering one or more changes in topology of network according to the impact score to improve fault tolerance of network.

Abstract: A computer implemented method for controlling a communications network. It is checked whether amount of handover failures from a first cell to a second cell exceeds a first threshold. Responsive to identifying that the amount of handover failures from the first cell to the second cell exceeds (301) the first threshold, a new cell identifier code is set (306) for the second cell in the communication network.
