Call Trace Management & AnalysisWhat is it?• Call Trace data sources provide important insight into real subscriber experience.
• Complements existing data sources
• Drive Survey Data
• OSS Data: Performance, Fault and Configuration Management

Call Trace ManagementThe Challenge Operators are struggling to
systemize their use of Call Trace data - it remains a narrow troubleshooting tool used by a few experts:
Lack of scalable systems to support the high volumes of data generated by Call Trace prevents continuous data collection
Inability GEO locate Call Trace data means that all statistics are defined at a sector level only.
The inability to collate Call Trace data with other sources such as Performance Management, Faults and Drive Survey data.
3. Difficulty providing end to end view of network.
1. Manual loading and analysis of Call Trace DataLack of GEO LocationNetwork configuration data needs to be found
2. Expert Engineers use individually traces and then discard results when finished. No GEO LocationNo data or expertise sharing.

ERICSSON GPEH SUPPORTSolution Overview
Copyright © Actix 2008. Commercial in confidence.
GPEH Overview General Performance Event Handling
(GPEH) function handles the management and collection of predefined events in the WCDMA RAN.
There are two types of events: Node-internal events - are events produced within the
RNC, due to a specific condition, for example the detection of missing neighbours, Compressed Mode activation.
Inter-node events (protocol events, layer 3 messages) - are protocol messages sent or received from UE, RBS, RNC. These being a subset of RRC, NBAP, RANAP, RNSAP protocols
Depending on what events are collected a single switch (250 sites) can generate between 6MBytes and 150MBytes every 15 minutes
Copyright © Actix 2008. Commercial in confidence.
Uses of GPEH Data Neighbor analysis
– Missing neighbor analysis– Existing neighbor analysis – Detection of Iur issues– Inter frequency analysis.
IRAT HO Analysis– Compressed Mode Activities– HO performance
RF performance & Radio Quality analysis– EcNo vs RSCP charts– Pilot Pollution– Other2Own Cell interference (DL)– SIR- Error, Transmitted CodePower,
UL interference– EcNo initial value, from RRC
request message Capacity Analysis
– DL power information analysis– Admission control analysis – DL channelization code allocation
analysis
HSPA Analysis– HS Cell change analysis – Average and Maximum HS user
analysis – Not defined Cell change
Neighbour analysis Connection Analysis
– Connection replay– Connection signalling
visualisation– RRC connection Metrics – Connection Metrics– Support for RRC, RAB message,

– Periodic KPI collection of network elements using GPEH
