Overview

GL’s End-to-End Wireless Network Simulation Test Suite provides you an advanced full-fledged “Live Network” at your company premises in any customized package to suit test requirements.

The entire test suite is built on common MAPS™ Platform framework architecture. 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 suite provides reliable integrated solutions to vendors and service providers for simulation, monitoring, troubleshooting the any wireless network, including, 4G, 3G, 2G and upcoming 5G. All functionalities conform to industry standards.

Test, monitor, and troubleshoot all the core network elements and traffic types within the Wireless infrastructure for deployment-readiness, functionalities, inter-operability, performance and latest mobile features. Test end-user applications, devices, and services on a simulated wireless infrastructure environment prior to deployment on a real-time network.

Why MAPS™ Wireless Network Simulation Test Suite?

Simple-to-setup and execute

  • All operations and individual nodes in a network can be controlled remotely from a Remote MAPS™ system
  • Simple test bed configurations to establish communication between different network elements, and the mobile phones
  • Ability to add unlimited number of user profiles, and scripts
  • The ready-to-use scripts makes testing procedure simpler which are used to quickly setup calls generating and verifying data traffic.  

Performance

  • Higher volume Voice and SMS calls (hundreds of calls/sec and 64,000 simultaneous calls/platform) with MAPS™ RTP HD appliance.

The application can remotely control multiple MAPS™ Servers running on different PCs from a single remote client application. One or more MAPS™ applications can be installed on each sever. With this practically all the nodes (network elements) associated with a protocol, including protocol standards and profiles can be remotely configured from a single client GUI. The Remote MAPS™ application communicates with the multiple MAPS™ Server via Listener over TCP/IP.

  • Multi-node and multi-interface simulation from a single GUI
  • Suitable for testing any core network, access network, and inter-operability functions
  • Single Licensing Server controlling server and client licenses (no. of users)
  • Unlimited number of remote client user can be defined at the server

GL’s Implementation of 5G NR LAB System

3GPP is defining both a new 5G core network, referred to as 5GC, as well as a new radio access technology called 5G “New Radio” (NR). Unlike previous generations that required that both access and core network of the same generation to be deployed (e.g. Evolved Packet Core (EPC) and LTE together formed a 4G system), with 5G it is possible to integrate elements of different generations in Standalone (SA) and Non-standalone (NSA) different configurations.

GL’s comprehensive Signalling and Traffic Emulation Suite for 5G/4G Wireless Networks, provides a unique “programmable, scriptable” framework that is independent of any protocol or under-lying network; it makes easier to perform cross-domain testing and transition tests to new technology such as 5G. The 5G core network and all its underlying entities can be accurately tested for functionalities and performance.

  • Basic connectivity of devices to a 5G network (including interoperability between 5G and LTE networks)
  • IMS (IP Multimedia Subsystem) services delivered over NR
  • Inter-operability and roaming scenarios
