Overview

“GPRS Performance Analyzer” is a stand-alone, offline software application for the analysis of protocol trace files (Tektronix RF5 format); it runs on any Windows PC (Windows NT SP5, 2000, XP) and on Tektronix protocol testers.

The application generates statistical measurements on signaling and user traffic. The graphical user interface provides different tabular and chart views, with user-definable grouping on different dimensions (Layer, Cell, User) and top-down analysis, from summary statistics to single-procedure trace.

Predefined reports on network Key Performance Indicators (KPI) and user-defined reports are available, and can be exported in different formats.

Function Description

The GPRS Performance Analyzer runs on any PC ( 128 Myte RAM and 800 MHz CPU are recommended for large recording files) running Windows NT SP5, 2000, or XP. License is protected with a hardware dongle (a parallel port is required for the dongle).

The application analyzes protocol trace files in Tektronix .(.rf5) format. It support GPRS Gb interface (Rel. 98 and Rel. 99 protocols).

The application processes decoded data from a Gb recoding file and generates a database of statistical and detail measurements. Data are then offered for analysis in a feature-rich graphical user interface.

Basic Statistics/ Analysis based on each Routing Area (RA), Cell and Layer

Message breakdown

Message counts can be easily grouped by Layer, Message Type, Cell

Layer specified statistics/analysis based on Routing Area (RA), Cell

Radio Status Cause
Error Cause for each Layer
Failure Rate and Cause for each Procedure
Call/Procedure Trace on the single occurrence of each procedure

Network QoS Analysis

BSSGP,LLC, IP layer throughput
LLC Discard Analysis
Easy identification of Peak Uplink (UL) and Downlink (DL) Traffic and of Radio problems
Easy comparison among the Cells to find the Cell with a problem
Sampling time can be set by the user. Can be as low as 10 seconds

GPRS Mobility Management/ Session Analysis

Procedure Response Time
Attach/PDP Context Activation Failure Rate
Cell Reselection Analysis
Radio problem
Session Count and Traffic Statistics by APN (Access Point Name)

IP and upper level protocols analysis

IP Protocol analysis
IP protocol Type
IP Header Error
IP fragmented data analysis
TCP/UDP Port analysis
TCP Window Size, Throughput, Round-Trip Time

Users’ Behavior Analysis

Throughput analysis for each user, at BSSGP, LLC, IP layer
IP Analysis
MS (Mobile Station) Flow Control Analysis
TCP Session Analysis

KPI Analysis

KPI reports help the user to identify “worst” performing network cells and to prioritize problems. Different scenarios (Procedure Success Rate, Procedure Response Time, Throughput) extract and display the first “n” cells that perform worse than the average of other cells or worse than user-defined thresholds.

Powerful Filter

Filters include Cell, User (IMSI), Message Type and Cause Value. Wild card searching is supported.

Characteristics

Three-dimension statistics and analysis

Conduct the data statistics for:

Each Cell

Each Layer

Each User

Gradually explore the failure cause from Cell, Layer and User.

Drill-down to detail

Navigate via mouse clicks from statistical overview of signaling procedures, down to single procedure/single user (IMIS) and down to procedure tracing, with accurate and complete decoding of every protocol message.

Powerful Visualization tools

Tables and charts (X-Y diagrams, pie charts) open with a single click.

Generate Customer-specific Report.

Report tables can be exported in standard Microsoft Excel Format
