GL Communications—LAB Solutions For End-to-End Wireless Networks (Comms—Testing)

[SatNews] 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.

Communications Network Lab (2.5G, 3G, 4G, IP, TDM)

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.

Message Automation & Protocol Simulation (MAPS™)

The network architecture 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.

Supported Technologies

  • 2G and 2.5G Network
    • Abis interface
    • A interface
    • Gb, Gr (GPRS interfaces)
    • MAP - B, C, D, E, F, G, H, Gc, Gr, Gf, Gd interfaces
  • 3G UMTS Network
    • IuCS, IuPS, IuH, Iu UP, Gn Gp interfaces
  • 4G LTE Network
    • S1, S3, S4, S11, S5/S8, S10, S16, X2 & SGs interfaces
    • Diameter-S6a, S6d, S13, Cx/Dx, Sh, Gx, Rx & SGI interfaces
    • 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,circuit switched traffic is provided 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.
