Call Trace Management & Analysis

What 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 Management

The 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.

Engineering Management

3. Difficulty providing end to end view of network.

2. Expert Engineers use individually traces and then discard results when finished. No GEO Location No data or expertise sharing.

1. Manual loading and analysis of Call Trace Data Lack of GEO Location Network configuration data needs to be found

Call Trace Management

Actix Solution A consolidated Call Trace Management solution that:
Automates the collection and analysis of the Call Trace data sources automatically identifying problems Automatically geographical locates Call Trace data (ActixOne 2.1) Provides out of the box analysis on par with Drive Survey analysis to deskill the analysis of Call Trace data. Enables organisational wide access to Call Trace data Correlates Call Trace with other Network Data sources for enhanced analysis and improved diagnosis.

Solution Overview

ERICSSON GPEH SUPPORT

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
