A computer-implemented method of monitoring a radio access network (RAN) is provided. The method includes receiving access stratum data that is a function of cell trace records (CTRs) associated with wireless communication transported to or from one or more cells of the RAN, wherein the CTRs are obtained at a granularity sufficient to detect one or more events, the events defining a segment or occurring during a segment, wherein a segment is defined by the beginning, end, or any handovers of a call included in the wireless communication. The method further includes detecting in the access stratum data one or more state transitions as indicated by the events and outputting an enhanced session record (ESR) including information processed from the access stratum data associated with the respective one or more detected state transitions.

Radio access network service mediated enhanced session records for artificial intelligence or machine learning

A method for assessing and improving network performance using video session data. Control plane signaling data comprising geographic location data from network monitoring equipment connected to a communications network is collected. Video session data comprising data of a plurality of video sessions from video monitoring equipment connected to the communications network is collected. The plurality of video sessions are associated with a plurality of mobile devices streaming videos on the respective mobile device across the communications network. The video session data and control plane signaling data within a cell of the communications network is correlated. The correlated data is provided to a communications network provider. The communications network is reorganized according to the correlated data.

A method for optimizing a radio access network includes receiving at least one area of the radio access network to be analyzed from a user and receiving a desired outcome from a user. A plurality of network monitoring parameters related to a user requested analysis is identified. The identified plurality of network monitoring parameters is correlated. A root cause analysis is performed using an automated classification model based on the correlated plurality of network monitoring parameters. A recommendation related to the desired outcome is generated based on the performed root cause analysis.

Optimizing radio cell quality for capacity and quality of service using machine learning techniques

A method for calibrating geolocation analytic system in a wireless network includes receiving a first data set including measurement data associated with a mobile device connected to the wireless network from a first data source. A second data set comprising external geo-location data associated with the mobile device is received from a second data source. The first data set is compared to the second data set to estimate geo-location of the mobile device and to identify one or more errors using calibration function. The identified one or more errors are corrected based on the comparison.

A method, computer program product and system for performing performance and root cause analysis of failures in a telecommunication network are provided. The telecommunication network includes User Equipment (UE) devices, core network and radio access network (RAN). Information related to impacted performance and failures reported in the telecommunication network is received. Telecommunication and transport network elements associated with the reported network performance and failures are identified. Performance and configuration data associated with the identified network elements is analyzed to identify one or more causes of the reported network failures. A root cause analysis of the reported network failures is performed using knowledge and statistical inference models for each of the identified causes to provide at least one recommendation for resolving the reported network failures.

Knowledge base radio and core network prescriptive root cause analysis

A method for analyzing a mobile radio network including the steps of collecting traffic data from call monitoring equipment connected to the mobile radio network, collecting signaling data from network monitoring equipment connected to the mobile radio network, correlating the traffic data and the signaling data related to a cell of the mobile radio network. and creating a graphical display of the correlated traffic data and the signaling data.

Apparatus and method for analyzing the quality of a cell in a mobile device network

A method, computer program product and system for determining quality of experience indicator in a telecommunication network including core network and radio access network (RAN) are provided. Quality of service indicators for a subscriber's session associated with the core network are received. Quality characteristics of a radio signal transmitted through the RAN or obtained from the user equipment and correlated to the subscriber's session are determined. A quality of experience indicator is generated for the subscriber's session based on the quality of service indicators for the core network and the quality characteristics of the radio signal.

Determining quality of experience confidence level for mobile subscribers

A system is described for collecting data records which have been correlated to subscriber, or end user, access network, core network, transport network, and application service information, referred to as end user correlated data records and utilizing those records in a wireless or wireline network to identify and address correctable conditions in a network, such as a wireless or wireline network. The system includes at least one probe in the network which is able to monitor network activity and provide detailed data records on that activity. These data records are sent to a mediation device that correlates those data records with subscriber and/or location data, to create the end user correlated data records. An intelligent application services device takes the end user correlated data records and examines the records to determine if there are any correctable conditions in the network or the end user devices.

A system and method for enforcing network policies is disclosed. Data is captured from network interfaces. A cell congestion level is determined from the captured data. Cells having a congestion level above a first threshold are identified. A first alert is transmitted to a network policy management entity when the cell is above the first threshold. Cells having a congestion level above a second threshold are identified. A second alert is transmitted to the network policy management entity when the cell is above the second threshold. The first threshold set at a point below a maximum capacity of the cell, and the second threshold set at a point near or at the maximum capacity of the cell.
