Patent number: 10966108Abstract: 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: GrantFiled: July 11, 2018Date of Patent: March 30, 2021Assignee: NetScout Systems, IncInventors: Robert William Froehlich, Ralf Kreher

Patent number: 8811289Abstract: 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.Type: GrantFiled: June 28, 2012Date of Patent: August 19, 2014Assignee: Tektronix, Inc.Inventors: Aleksey G. Ivershen, Vignesh Janakiraman, Martin Winau, Ralf Kreher, Julien Schnerrer, Martin Polak

Patent number: 8744479Abstract: 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.Type: GrantFiled: August 26, 2009Date of Patent: June 3, 2014Assignee: Tektronix International Sales GmbHInventors: Ralf Kreher, Martin Polak
