Newsletter: GL Announces End-to-End Wireless Network LAB Solutions (2G, 3G, and 4G)

Welcome to another November 2013 issue of GL Communications' Newsletter providing information and insight into our Complete End-to-End Wireless Network LAB Solutions (2G, 3G, & 4G). GL provides both Radio Access and Circuit Core Network versions as shown below.



Emulate 2G, 3G, & 4G Wireless Networks End-to-End

Overview

GL supports a wide range of wireless network simulators, which provide reliable integrated solutions to vendors and service providers for Testing, Simulation, Monitoring, and Troubleshooting 2G, 3G and 4G mobile networks. These networks can be invaluable for protocol characterization and testing, performance measurement, and training.

GL's 'MAPS™ 2G, 3G, and 4G Lab Suite' along with Radio Access Elements are a set of test systems used to provide an advanced full-fledged network environment that enables user to test their applications, devices, and services prior to deployment on a real-time network. The test suite can be used to simulate all or specific elements within wireless networks infrastructure using simple ready-to-use test bed setups. The test systems allow for simultaneous execution of various test cases across networks. It also allows for performance and conformance testing compliant with 3GPP standards.

The network architecture shown below outlines the implementation of Wireless Networks Lab with the help of GL's MAPS™ Platform. With the integration of third party tools for radio access network, and widely available mobile phones, the entire wireless network can be operated in real-time.


2G, 3G, and 4G scenarios that can be simulated using MAPS™ are discussed in the following sections.

GL's Implementation of GSM-GPRS LAB System

MAPS™ 2G Lab System can test BSC completely by simulating several BTS nodes on Abis interface. Similarly, MAPS™ 2G LAB System can also test MSC and SGSN/GGSN elements on the A and Gb interfaces respectively. With this simulator we provide circuit switched traffic through RTP.

MAPS™ SGSN emulator can be configured to simulate both SGSN and BSC nodes as depicted in the network setup below. It supports both control-plane and user-plane packet switched traffic.

MAPS™ 2G Lab Systems can be used to simulate multiple instances of nodes in network such as MSC, BSS, SGSN, and GGSN to perform functional and load/stress testing.

The lab system can operate with real mobiles or optionally with a simulator such as GL's TRAU Testing Solution.

Configurations

MAPS™ (Message Automation and Protocol Simulation) is dongle based licensed software supporting a variety of protocols under a common architecture. Ready-to-use scripts makes testing simpler and allows users to quickly setup calls for generating and verifying data traffic. The scripts are event-driven and provide fine control over call behavior.

Complementing the simulation capability in MAPS™, is GL's PacketScan™, an all-in-one call signaling and traffic monitoring tool, which can be used to capture and analyze signaling and data in a live network across any IP interface. Also available are other GL's protocol analyzers such as GSM, GPRS, and UMTS analyzers over TDM and Optical interfaces.

MAPS™ can be used in any of following configurations depending on the device or network under test requirements -

Single Interface Test Setup - A single interface can be tested using MAPS™, which can embed all the functionality of the entities interacting with the interface.
   
Multi Interface Test Setup - DUTs over different interfaces can be tested simultaneously using a single MAPS™, which provides all of the required functionality over multiple interfaces.
   
   
Wrap Around Test Setup - Vendors can test their DUT by replacing all the nodes interacting with the device with appropriate MAPS™ products.
