GPRS Analysis for Gb and Gn Interface

Overview

GPRS (General Packet Radio Service) permits continuous data connectivity over wireless GSM

networks. For example, mobile phones and laptops can be used to send and receive data over the

Internet, e.g. e-mail and WEB surfing are typical examples.

GLs GPRS Analyzer performs real time (and offline) analysis across the Gb (T1/E1) and Gn

(Ethernet) interface. The GPRS Analyzer when connected between SGSN and BSS elements of

a GPRS network permits the monitoring of Gb interface. Similarly, when connected between

SGSN and GGSN elements, permits monitoring of the Gn interface.

GL Communications supports the following types of GPRS analyzers:

Real-time GPRS Analyzer (Pre-requisites: GL's T1/E1 internal cards or USB T1/E1external units, required licenses and Windows 2000/XP/Vista Operating System)

Offline GPRS Analyzers (Pre-requisites: Hardware Dongle, and Windows 2000/XP /VistaOperating System)

Main Features Supports filtering and search based Gb Interface parameters such as Data Link, Network

Service, BssGp, LLC, Gprs Mobility/Session Mgmt, SMS, TOM and SNDCP and Gn

Interface parameters such as Data Link, MAC, IP, UDP, TCP, ICMP, GTP/GTP, GTP_IP

GTP_UDP, and GTP_TCP.

Summary View displays GB Interface information such as DLCI, FECN, BECN, SAPI,CTL, Session Mgmt Message, and more and Gn Interface information such as Protocols,Source/Destination IP Address, UDP Source/Destination port, TCP Source/Destination

Port, Message Type, and etc in a tabular format.

Detail View displays decodes of a user selected frame from the Summary View. Hex dump View displays the frame information in HEX and ASCII octet dump of a user-

selected frame from the summary view.

Statistics View displays statistics based on frame count, byte count, frames/sec, bytes/secetc for the entire captured data. It also displays Total Frames, Average Frames and

Utilization, Maximum Frames and Utilization, and so on.

Call Detail View displays called/ calling number, released calls, call status, & more. Supports simultaneous decode of multiple streams of GPRS traffic on different T1/E1

channels.

Capability to export Summary View details to comma separated values (CSV) format forsubsequent import into a database or spreadsheet.

Capability to export detail decodes information to an ASCII file. Streams can be captured on the selected time slots (contiguous or non-contiguous), sub-

channels or full bandwidth in Gb Interface and Ethernet based capture and filtering

capabilities in Gn Interface.

Summary, Detail and Hexdump Views

The analyzer displays summary, detail and hex dump view in

different panes. The summary pane displays GB Interface

information like DLCI, FECN, BECN, SAPI, CTL, Session Mgmt

Message etc and Gn Interface information like Source/Destination

IP Address, UDP Source/Destination Port etc. User can select a

frame in summary view to analyze and decode in the detail view.

The Hex dump view displays the frame information in HEX and

ASCII formats.

Real-time and Offline Analysis

Users can capture and analyze GPRS frames using either real-time

or offline analyzers, and record all or filtered traffic into a trace

file. The recorded trace file can be exported to a comma-delimited

file, or analyzed offline. The recorded trace file can then be

analyzed offline and exported to ASCII file, or printed. Real-time

capturing on Gb interface requires user to specify timeslots, bit

inversion, octet bit reversion, user/network side, FCS, and data

transmission rate.

*Specifications and features subject to change without notice.

Filtering and Search

Users can record all or filtered traffic into a trace file. Filter and

search capabilities adds a powerful dimension to the GPRS

Analyzer. These features isolate required frames from all frames

real-time /offline.

For Gb interface, users can specify custom values for frame lengt

to filter frames during real-time capture. The frames can also be

filtered after completion of capture according to Frame Number,

Time, C/R, SAPI, CTL and more. For Gn Interface, Ethernet base

real-time capture filtering capabilities based on Source/DestinatioIP address, Mac Layer Address, and more can be applied.

Similarly, search capability helps user to search for a particular

frame based on specific search criteria.

Call Detail Record & Statistics View

Call trace defining important call specific parameters like Call ID

Call Status, Call duration, Device Number, BVCI, Call type etc a

calculated for Gb Interface and IMSI, NSAPI for Gn Interface.

Call traces can also be logically grouped with each group

comprised of unidirectional (either Forward or Backward) dat

links. Statistics is an important feature available in GPRS analyze

and can be obtained for all frames both in real-time as well as

offline mode. Various statistics can be obtained to study the

performance and trend in the GPRS network based on protocolfields and parameters.
