1. www.nethawk.fi 16th December 2008 New in NetHawk M5 – Air interface monitoring One tool for both air and network interface real time monitoring

2. www.nethawk.fi 16th December 2008 New interfaces in NetHawk M5 Playground Supported air interface

3. www.nethawk.fi 16th December 2008 Solution in brief >NetHawk Air Interface Test UE is used as an adapter for capturing air interface signaling and user data. NW Element NW Element Test UE USB Simultaneously with M5 monitoring other interfaces: > Signalling can be seen in real time correlated with other interfaces (Iub, Iu…) in M5 Protocol Monitor application. NW Element NW Element 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. Trace file Test UE Trace file

4. www.nethawk.fi 16th December 2008 Complete E2E test solution PS 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. Test UE Trace file Iu-PS Trace file 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. www.nethawk.fi 16th December 2008 >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 eEPOS TM –Source data for QoS monitoring of live networks, e.g. mobile broadband subscribers New player on field measuring M5 RF Probe – Automatic RF measurement reports Meas report (.rec) Test UE Meas report (.rec)

6. www.nethawk.fi 16th December 2008 >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. New player on field measuring M5 RF Probe – Remote configuration SMS: 0403010981 0403010982 Start tracing;DUAL… Test UE Control mobile

7. www.nethawk.fi 16th December 2008 >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 New player on field measuring M5 RF Probe – Automated traffic generator Trace file Test UE Trace file Start(5:00PM) Call(+358403010 598,,10,20s); Wait(30s); SMS(+358403010598, 10,”TestSMS”); Wait(30s); WWW(www.nethawk.fi,,10,60s);

8. www.nethawk.fi 16th December 2008 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 16th December 2008 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 tool investments and reduces the amount of working on the field!
