  • 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.
    Type: Grant

  • Patent number: 9485679
    Abstract: 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.

  • Publication number: 20150163624
    Abstract: A method for determining mobile device location in a wireless communication network having plural base stations and at least one repeater for communicating with a mobile device is performed by a geolocation detection program for locating a mobile device. The geolocation detection program determines whether a signal received from the mobile device has passed through the at least one repeater.

  • Patent number: 8811289
    Abstract: Systems and methods for Long Term Evolution (LTE) interface correlation are described. In some embodiments, a method may include receiving a first message, the first message having been intercepted over an air (Uu) interface of an LTE network (e.g., probed via a Common Public Radio Interface (CPRI) between an Evolved-Universal Terrestrial Radio Access Network (UTRAN) Node B (eNB)'s remote radio head and baseband processing unit), the first message having a first identifier. The method may also include receiving a second message, the second message having been intercepted over the S1 interface between the eNB and a Mobility Management Entity (MME) within an Evolved Packet Core (EPC) portion of the LTE network within a given time window from the first message, the second message having a second identifier. The method may further include correlating the first and second messages in response to a match between the first and second identifiers.

  • Patent number: 8744479
    Abstract: The present invention relates to a method for locating at least one mobile radio subscriber in a mobile radio network. The mobile radio subscriber transmits a measurement report that includes an itemization identifying at least two transmitting stations. A value correlated with the receive field strength of a signal from the transmitting stations is allocated to each transmitting station. A table is organized according to geographic units of a presettable area. A pre-calculated value correlated with the receive field strength of a signal from a transmitting station is allocated to each transmitting station. The transmitting stations are organized according to the values correlated with the receive field strength of the signal from the respective transmitting station. The location of the mobile radio subscriber is determined based on the geographic unit meeting at least one presettable criterion.

  • Patent number: 8326320
    Abstract: The present invention relates to a method for locating at least one mobile radio subscriber in a mobile radio network, wherein to each transmitting station a value correlated with the receive field strength of a signal from this transmitting station is allocated; including the following steps: a) from the information determined upon connection setup, a table is created per cell, in which at least one distance parameter to the transmitting station of the cell is allocated to the respective receive field strengths; b) for at least one value correlated with the receive field strength and transmitted in the measurement report, the allocated distance parameter to the transmitting station of the respective cell is read out from the table created in step a); and c) determining at least one point satisfying the distance parameter(s) read-out in step b).
