Abstract: A method for analysing performance of a network by managing network data relating to operation of the network is disclosed. The method comprises receiving a plurality of network data records from at least one network data source, processing the received plurality of network data records into a plurality of network data documents, each network data document corresponding to a received network data record, assembling the plurality of network data documents into document groups, generating statistical data for terms appearing in the document groups, and for at least one term, performing anomaly detection upon the statistical data for the term in the document groups, and detecting an anomaly in the term. The method further comprises performing at least one of identifying the term as an anomalous term, identifying the document group containing the anomaly as an anomalous group, and/or identifying a document containing the anomalous term as an anomalous document.

Abstract: A method for allocating radio channels for use in a wireless cellular network is disclosed. The method comprises receiving from a second system an authorization for the wireless cellular network to use radio channels The method also comprises calculating weights for a plurality of combinations of cells of the wireless cellular network with the radio channels from the second system and assigning at least some of the radio channels to at least some of the cells of the wireless cellular network based on the calculated weights. Apparatus and a computer program product for carrying out the method are also disclosed.

Abstract: Reallocation of a capacity boost cell between first and second operators in a cellular radio communications network is carried out by detecting a drop in load for the first operator, in the area of coverage of the capacity boost cell, below a first threshold, and reallocating automatically the capacity boost cell to the second operator in response to the detected drop in load, if the first operator has authorised a reallocation. The capacity boost cell can be reallocated automatically back to the first operator in response to detecting a subsequent increase in load above a second threshold for the first operator. This can improve utilisation of the capacity boost cell during low load periods while still having it available for the first operator for high load periods, and can provide access to additional capacity for the second operator without need for costly additional infrastructure.

Abstract: A method of identifying a network object group from a plurality of network objects (x1 to xM) of a communications network comprises grouping network objects based on a function of a plurality of key performance indicators, KPIs (k1 to kN) which are common to the plurality of network objects (x1 to xM).

Abstract: The present disclosure relates to coverage monitoring and in particular it relates to determining radio coverage, e.g. for small cell deployment in a building. The disclosure relates to methods for coverage determination as well as to corresponding devices and computer programs. According to one aspect, the disclosure proposes a method, performed in a wireless device 10, of determining radio coverage. The method comprises obtaining S1 at least one path along which radio condition measurements are to be performed and performing S2 radio condition measurements along the at least one path. The method further comprises determining S3 position estimates, wherein at least some of the position estimates correspond to the radio condition measurements.

Abstract: The present disclosure relates to coverage monitoring and in particular it relates to determining radio coverage using correlated radio condition measurements and position estimates, for example for small cell deployment in a building. The disclosure relates to methods for coverage determination as well as to corresponding devices and computer programs. According to some aspects, the disclosure proposes a method, performed in a node 10, 110 of determining radio coverage of at least one small cell base station in a wireless communications network. The method comprises the steps of obtaining radio condition measurements, wherein a respective first time value is associated to each radio condition measurement.

Abstract: A method for analysing performance of a network by managing network data relating to operation of the network is disclosed. The method comprises receiving a plurality of network data records from at least one network data source (102), processing the received network data records into a plurality of network data documents, each document corresponding to a received network data record (104) and assembling the network data documents into document groups (108). The method further comprises generating statistical data for terms appearing in the document groups (110) and for at least one term, performing anomaly detection upon the term statistical data for the document groups (114) and, if an anomaly is detected, performing at least one of identifying the term as an anomalous term (120), identifying the document group containing the anomaly as an anomalous group (122), and/or identifying a document containing the anomalous term as an anomalous document (124).
