  1. www.nethawk.fi New in NetHawk M5 – Air interface monitoringOne tool for both air and network interface real time monitoring

  3. NW Element NW Element NW Element NW Element Trace file www.nethawk.fi Solution in brief • NetHawk Air Interface Test UE is used as an adapter for capturing air interface signaling and user data. Simultaneously with M5 monitoring other interfaces: > Signalling can be seen in real time correlated with other interfaces (Iub, Iu…) in M5 Protocol Monitor application. Stand-alone – Test UE with M5 RF Probe application stores trace file to its internal memory: > Trace file can be analysed as such with M5 and also merged with trace files from other network interfaces. Test UE Trace file Test UE USB Trace file

  4. Trace file Trace file Test UE Iu-PS www.nethawk.fi Complete E2E test solutionPS session troubleshooting utilising automatic File Merge • Test UE is used as a stand-alone for recording PS session activations on the site meanwhile M5 Analyser is recording Iub and Iu-PS interfaces around RNC. • Trace files are merged after the test session automatically. • The merged trace file is analysed on M5 Analyser: • The subscriber filtering and session phases can be seen with the Call&Session Analysis application. • Detailed protocol messages from the failed or abnormally terminated sessions can be analysed by using Protocol Monitor.

  5. Test UE Meas report (.rec) Meas report (.rec) Meas report (.rec) Meas report (.rec) www.nethawk.fi New player on field measuringM5 RF Probe – Automatic RF measurement reports • Test UE is operating as a mobile Probe for measuring the essential RF quality parameters and KPIs on the field. • Measurements reports (.rec format) are sent automatically to file server by using FTP: • GPS location included • Measurement reports can be analysed with M5 or visualised in 3rd party systems: • Network designing and optimisation tools e.g. ECE eEPOSTM • Source data for QoS monitoring of live networks, e.g. mobile broadband subscribers

  6. Test UE SMS: 0403010981 0403010982 Start tracing;DUAL… Control mobile www.nethawk.fi New player on field measuring M5 RF Probe – Remote configuration • M5 RF Probe software can be configured remotely by using SMS commands: • Start/stop tracing • Network selection • Bearer type etc. • SMSs can be sent to single Test UE or broadcast many of them. • Makes possible to start tracing at the same time in all M5 RF Probes on the field.

  7. Test UE Trace file Trace file Trace file Start(5:00PM) Call(+358403010 598,,10,20s); Wait(30s); SMS(+358403010598, 10,”TestSMS”); Wait(30s); WWW(www.nethawk.fi,,10,60s); www.nethawk.fi New player on field measuring M5 RF Probe – Automated traffic generator • Test UE is operating as an active mobile on network. Capability to generate: • CS calls • SMS • PS sessions including application protocols HTTP, FTP... • Video calls utilising streaming protocols • Easy writing test case scripts allow to define • Timers • Loops etc. • SMS control enables to change the test script remotely

  8. www.nethawk.fi Use cases • Real-time Air IF monitoring simultaneously with other interfaces: • Functional testing of different transactions like CS calls, registrations, PS sessions, etc. in laboratory environment: • Monitoring of RF, RAN and Core interfaces at the same time. • End-to-end signalling and user data packets delay and quality measurements in laboratory or in real network: • Continuous QoS monitoring of 3G broadband services. • Acceptance testing after BTS installation or other network element upgrades: • Network dimensioning and optimization: • How new cell or additional sector operates with neighbour cells.

  9. www.nethawk.fi Benefits • Air interface and other network interfaces signalling can be analysed in the same tool together: • Network side problems inaccessible for pure drive test tools. • Enables end-to-end QoS measurements: • IP traffic delay, throughput, etc. • Subjective quality analysis for CS/PS voice and data. • Light and cost effective solution for basic level RF monitoring: • One heavy drive test tool can be replaced with several Air Interface Test UEs: • Covers many cells/sites at the same time • Remote usage and configurability • Full compatibility with M5 Analyser makes possible to troubleshoot Air IF data on low level --> Enables to reduce drive test toolinvestments and reduces the amount of working on the field!

  11. www.nethawk.fi M5 RF Probe • Air Interface Test UE is delivered with a Symbian based software application: • Stores Air IF signalling and user data when terminal is used as a stand alone test unit. • Trace file is in .rec format and can be copied into PC for analysis with M5. • User can do following operations: • Start and stop recording • Set network mode (GSM, UMTS, Dual) • Lock test terminal into user defined channel: • GSM – band and channel • UMTS – UARFCN and scrambling code • Select which information is stored into trace file: • Signaling bearers (control plane) • Data bearers (user plane) • Note! HSDPA excluded.

  12. www.nethawk.fi Air interface monitoring with M5 (1/4) • M5 sees the Air interface Test UE as any other interface adapter. • Terminal’s measurement options are configured via Adapter Options: • Trace settings • Signalling • User Data • Network selection • 3G • GSM • Automatic

  13. www.nethawk.fi Air interface monitoring with M5 (2/4) • RF signaling (RR, RRC, RLC, MAC) can be seen in real time in Protocol Monitor: • Detail level, format, colour settings of decoding with Layer Settings.

  14. www.nethawk.fi Air interface monitoring with M5 (3/4) • Trigger and Counter applications can be used normally. • Recorder application can store Air interface traffic into trace file and trace can be analysed with Protocol Monitor as usual.

  15. www.nethawk.fi Air interface monitoring with M5 (4/4) • Signalling can be analysed with Call & Session Analysis application as well: • Air interface signalling can be correlated with signalling from other network interfaces.
