• Traffica as a data source for - NetAct Monitor (alarms)- NetAct Reporter (PIs)- NetAct Service Quality Manager (GSM and GPRS: alarms via
Monitor, GSM: PIs)- External systems (raw data via Traffica Database Export)
• Traffica as a surveillance tool- Graphs give a daily summary of network and service situation
and help in benchmarking- User-defined graphs can focus to customer specific services- Alarms indicate problems in the network
• Traffica as a troubleshooting tool- Clear Codes help determine the cause of problems- Traffic News for tracing details of problematic events- Graphs allow drilling Clear Codes and other data values into
different network entity levelsMSC / BSC / LAC / Cell, MSC/CGR / PCM / TSL
Traffica in Service Assurance

• Success of calls, SMSs and GPRS events • Dropped calls, setup problems and handover failures
• Per RNC/BSC, SAC/LAC, Cell • Per CGR, PCM-TSL
• Failed GPRS events• Per RAC, LAC, Cell, GGSN, PAPU
• International destinations and roaming intensity• Average call duration, paging times, delivery times• Mobile type usage• Used services and contacted Access Point Names
Nokia NetAct Traffica Visualising with Real-time
graphsNokia provides an extensive selection of predefined real-time graphs e.g:
• Voice and Data calls• MO and MT Short Messages• HSCSD• Dual band • Attaches & Detaches• Routing Area Updates• PDP Context Activations, Modifications and Deactivations

Service Specific Monitoring
• In Traffica, Service specific monitoring can be implemented based on, for example
- IMSI or Direction_Number ranges
- Traffic Category, Route Category
- IN indicator- TCH Access Information- Used CGRs
• Any other data in the RTT can be combined to the service definition to allow, for example, drill-down functionality

Monitor Erlangs• Traffica allows you to monitor erlangs toward, for example, different
destinations and route categories (VMS, PSTN): note that Traffica graphs always provide an Erlang approximation, not the exact Erlang value
• Erlang summary is automatically provided with Traffica Summary Report Tool

Monitor Call Lengths
• Since Traffica registers the call start and end times, it is possible to calculate call length with Traffica
• The average call length can be monitored on different network entity levels, and call specific length is visible in Traffic News query output
• Very short calls may give indications of connection quality problems, and can be monitored using for example tailored graphs

Using Alarms to Detect and Predict Problems
• User can define KPI-based alarms that are triggered by threshols
- Detect problems proactively- Detect how physical network
problems affect actual traffic
