Traffica in Service Assurance
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 levels MSC / BSC / LAC / Cell, MSC/CGR / PCM / TSL

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 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
