A Real-Time Monitoring Tool for Nokia Networks

• Wide application within the operator´s business processes

- Real-time traffic monitoring & trouble-shooting tool

- Tool for subscriber and network behaviour analysis

• Speech & data call and short message specific performance data in real-time via Nokia MSCs from the entire network

• Visualises the network traffic with real-time graphs and alarms

• Gives very detailed information on subscriber level with off-line tools

• 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
