MAPS™ GPRS Gb Interface Emulator

Overview

MAPS™ is designed to simulate GPRS Gb interface messages and signaling specification as defined by 3GPP standards. MAPS™ GPRS Gb currently supports Gb interface between the BSS (Base Station Subsystem) and the SGSN (Serving GPRS Support Node) over IP transmission protocol. Emulation over Frame Relay transmission protocol will be supported in future.

Besides testing network elements (SGSN and BSS), the tester also involves error tracking, regression testing, and load testing/call generation. MAPS™ GPRS Gb interface Emulator supports various procedures including Network Service Control, Identity Check, Combined GPRS / IMSI Attach, and Routing Area Update. It can run pre-defined test scenarios against the interface test objects in a controlled & deterministic manner.

MAPS™ GPRS Gb Interface Emulator supports powerful utilities like Message Editor, Script Editor, and Profile Editor which allow new scenarios to be created or existing scenarios to be modified as per the protocol standards listed in the table below.

GL’s MAPS™ GPRS Gb software benefits Network Equipment Providers of SGSN, and BSS entities, with –

Accelerated time to market
Reduced development costs
Reduced project risk of internally-developed applications
