MAPS™ GSM Abis Interface Emulator

Overview

GL’s MAPS™ is an advanced protocol simulator/tester for GSM Abis interface simulation over TDM and IP that can simulate BTSM messages and signaling specification as defined by 3GPP standards. The tester supports testing network elements BTS and BSC, Error tracking, regression testing, conformance testing, load testing/call generation and generation of high volumes of GSM traffic. It is able to run pre-defined test scenarios against GSM Abis interface test objects in a controlled & deterministic manner.

MAPS™ emulator for GSM Abis protocol over TDM (with XX693 license) and over IP (with PKS134 license) supports powerful utilities like Message Editor, Script Editor and Profile Editor, which allow new scenarios to be created or existing scenarios to be modified using BTSM messages and parameters.
MAPS™ GSM Abis over TDM supports TRAU traffic with additional licenses. The TRAU Traffic commands includes Transmit TRAU DTMF Digits (Send TRAU File, Send TRAU Tones), Receive Actions (Monitor TRAU Digits, Rx TRAU File, Monitor TRAU Tones), and Stop Traffic Actions.

GL has enhanced the MAPS™ protocol emulation tool to simulate multi-protocol and multi-interface offering a complete range of test solutions, covering the entire 2G, 3G, and 4G network.

By mimicking real-world customer behavior in lab environments, our solutions allow mobile operators and equipment manufacturers to verify their wireless networks before deployment. In other words, one can setup a virtual real-time network simulating all the network elements using “MAPS™ 2G Wireless Lab Suite”. The test suite supports simulation of GSM Abis, GSM A, C/D/E, Gb, and GnGp interfaces.

MAPS™ GSM Abis over IP supports CS Domain RTP traffic with additional PKS102 licenses. Supported RTP traffic types include – Auto Traffic Tx Rx File, Tones, Digits, FAX, User-defined traffic, and IVR.

With the purchase of RTP Core license (PKS102), MAPS™ GSM Abis supports transmission and detection of CS Domain RTP traffic such as, digits, voice file, single tone, dual tones, IVR, FAX*, and Video*. With regular RTP traffic, the maximum Simultaneous Calls up to 2500, and Calls per Second up to 250 is achievable. Almost all industry standard voice codec supported.

GL also provides an independent GUI based GSM protocol analyzer for TDM interfaces (optional application – XX150) and PacketScan™ for IP interfaces (optional application – PKV100) for online capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.

Possible applications include:

Setup a virtual real-time network simulating 2G-GSM GPRS network elements using ‘MAPS™ 2G Wireless Lab Suite’
Multi-protocol, Multi-interface Simulation
Provides fault insertion, and erroneous call flows testing capability.
Performance testing, Load Testing, Function al testing, Regression testing and Conformance testing of network elements.
Ready scripts makes testing procedure simpler, less time consuming and hence time to market products.
Test response of network against protocol message modification, or corruption
Inter-operability testing of networks
Wrap-around testing (WAT)
SMS Testing from within the Wireless Infrastructure using MAPS™
