  • Patent number: 11265786
    Abstract: 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.

  • Patent number: 10966108
    Abstract: 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.

  • Patent number: 10382883
    Abstract: 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.

  • Publication number: 20150072714
    Abstract: A method for providing accurate geolocation information is described in which geolocation information is received from a plurality of position information sources. A confidence indicator value is associated with each of the plurality of position information sources. Geolocation information received from two or more of the plurality of position information sources is combined based on the confidence value associated with each of the plurality of position information sources. A geolocation accuracy indicator (e.g., a graphical indicator) is provided to a user.

  • Patent number: 8849800
    Abstract: 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.
