Patent number: 11153443Abstract: A system and method is provided for calculating session initiation protocol (SIP) key performance indicators (KPIs) for multimedia communication in a network accessing network packets monitored over time. The method includes accessing network packets monitored over time, detecting a SIP response message of the monitored network packets, and accounting for the detected SIP response message in a time window of a series of consecutive time windows that includes the SIP response message's associated observed time. The SIP response message has an associated observed time at which the monitored SIP message was observed during monitoring. The method further includes pairing a SIP request message expected to be paired with the detected SIP response message with the detected SIP response message and accounting for the paired SIP request message in the time window with which the detected SIP response message is accounted.Type: GrantFiled: February 22, 2017Date of Patent: October 19, 2021Assignee: NetScout Systems, IncInventors: Bruce A.

Patent number: 10631182Abstract: First and second pluralities of packets transmitted between UE and the USN over a first interface and a second interface are continuously captured. The first, second and third pluralities contains temporary and permanent identifying information and ciphering key information. A fourth plurality of packets transmitted between the USN and a HSS over a fourth interface is captured. The temporary, permanent identifying information and the ciphering key information are correlated to determine mappings stored in a data repository. A fifth plurality transmitted over a fifth interface is continuously captured. Permanent identifying information corresponding to the temporary identifying information retrieved from the unciphered packets of the fifth plurality is retrieved from the data repository based on the stored mappings. NAS deciphering key information corresponding to the retrieved permanent identifying information is retrieved.Type: GrantFiled: April 17, 2017Date of Patent: April 21, 2020Assignee: Netscout Systems, Inc.Inventors: Tauras Liubinskas, Abhishek Saraswati, Subappriya Muthuchamy, Apurva Prakash, Sandeep Prasad

Patent number: 10111147Abstract: A plurality of data packets is received from a wireless communication system. At least one of SIP signaling messages and S1-AP signaling messages associated with calls being made or attempted in the wireless communication system are analyzed for a specified time period to identify one or more dropped calls. At least one of SIP signaling error codes and S1-AP signaling cause codes associated with the identified dropped calls are analyzed to identify one or more call drop reasons. An ASI data set is generated based on the analysis of the at least one of the SIP signaling messages and the S1-AP signaling messages and based on the analysis of the at least one of the SIP signaling error codes and the S1-AP signaling cause codes.Type: GrantFiled: October 6, 2017Date of Patent: October 23, 2018Assignee: NetScout Systems, Inc.Inventors: Sandeep Prasad, Abhishek Saraswati, Tauras Liubinskas, Erdem Uysal, Claudio Guerrini, Rajeev Nadkarni, Brandon Wayne Bass
