  15. Patent-pending solution for user-plane analysis NetHawk iPro with M5 – User plane analysis

  16. NW Element NW Element Test UE USB Air interface monitoring on site • NetHawk Air Interface Test UE is used as an adapter for capturing air interface signaling and user data. • NetHawk M5 can combine and synchronise in real time the air interface signaling with the signaling from other interfaces (Iub, Iu…) in Protocol Monitor application.

  17. Test UE NW Element NW Element Trace file Air interface monitoring in the field • Air interface test UE stores trace file to its internal memory with the help of NetHawkM5 RF Probe application: • Trace file can be analysed as such with NetHawkM5 and also merged with trace files from other network interfaces.

  18. Network monitoring with the NetHawk M5 • Analysis of the captured data with the help of intelligent applications in real-time/offline: • Detailed root-cause analysis with Protocol Monitor • Troubleshooting with Call & Session Analysis • Speech playback and recording of CS calls • Objective voice quality measurements • Delay, throughput, jitter, packet count and packet loss measurements with QoS • Over 100 pre-defined KPIs with Network Statistics • Data-mining: Storing of xDRs, KPIs and QoS counters to database and doing graphical analysis with Diagnostics reporting tool

  21. Adjustable views in M5 -Docking panels allows user to define the analyser views the most efficient way! E.g. in PM, Detailed Decoding view can be moved from bottom to side. -Floating applications let user to move any application out of M5 working area, even to different screen!

  22. Call & Session Analysis • Real-time tracing of CS calls, PS sessions, handovers with phase information: • LTE: S1, EPC (control plane) • UTRAN: Iub, Iu-CS, Iu-PS • Correlation: Iub with Iu • GERAN: Abis, A, Gb, A+, Ater, UMA Up • Correlation: Abis with A, A+, Ater, and Gb with Gn, Gi • Core: MAP, ISUP, INAP, CAP, Mc/Nc/Nb, Gn, Gi, Gs • Correlation: MAP with Iu, Iub, or MAP with Abis, A, Mc with Nc, Nb • IMS: SIP with user plane, Diameter • Setup time measurements between user-defined messages.

  23. Call & Session Analysis GUI Calls/sessions correlated over the monitored interfaces Available columns, e.g. over 200 LTE specific columns Detailed decoding with a mouse click

  24. Speech Playback for Iub, Iu-CS, Abis, A, Ater and SIP interfaces • Listening to speech of selected voice calls through PC’s loudspeakers. • Recording speech to .wav-format e.g. for PESQ analysis. • Abis Scanner for easy configuration of Abis voice listening • Supported speech codecs: • G.711 (A-law/µ-law) • GSM HR, GSM FR, GSM EFR • AMR-NB, AMR-WB • G.723.1 • G.726 • G.729, G.729A, G.729B, G.729AB • iLBC PESQ = Perceptual Evaluation of Speech Quality

  25. Voice Quality Measurement (NINA+) • No-reference approach for evaluation listening quality of speech files. • NetHawk solution is based on SwissQual’s NiNA+ algorithm: • In comparison to ITU-T P.563 – where SwissQual is also owner partially – NiNA+ has much less complexity. • Restricted to narrow-band speech: • AMR-WB signal can be analysed but only the narrow-band spectral parts are taken into account allowing to predict transmission errors of the AMR-WB against error-free AMR-WB transmissions. • Minimum period of the sample speech must be of five seconds. Speech period can be more than 20 seconds but the only first twenty second is analysed: • NiNA+ makes use of a sophisticated pre-processing step that checks for silence and sufficient speech activity in the signals.

  26. Voice Quality Measurement (NINA+) – parameters

  27. Network Statistics • Based on the traced CS and PS transactions at Iub, Iu-CS, Iu-PS, Abis, A, Gb, MAP and ISUP interfaces: • Call setups, dropped calls, SMS, PDP context activations, routing area updates… • Stored to database • Illustrated in graphics with Diagnostics reporting tool: • Count of occurrences • Success/failure rates (Key Performance Indicators) • Distribution of failure causes to LAC and Cell level • Own KPIs with protocol counters
