Message Automation and Protocol Simulation – MAPS™

5G Core Network Simulation using MAPS

The demand for 5G is not limited to High speed data & high quality voice services. It is going to play an important role in other vertical industries like Automotive, Health Care, Smart cities etc. This requires low latency, scalable and customizable network that can be tailored to requirements from multiple services and vertical markets. Testing of such complex network is very challenging & GL's 5G testing products based on feature rich MAPS™ emulation framework is of great value.


  • GL’s MAPS™ supports simulation of 5GC network interfaces - N1, N2, N3, N4, N6, N8, N9, N10, N11, N12, N13, N14, N22, and other GTP interfaces

  • Supports High Density user plane traffic generation using PacketLoad and RTP HD.

  • Supports generation and verification of traffic over LTE, including VoLTE (Voice), FTP, Web (HTTP), Video

  • Regular software updates to meet compatibility with latest 3GPP specifications
  • Compliance with HTTP 2.0 & OpenAPI

Any of the network elements in the above architecture can be replaced with user's DUT to perform single interface, multi-interface, or wrap-around testing -


  • Single Interface Test Setup - With this solution, a single interface can be tested using MAPS™, which can embed in itself all the functionalities of the entities interacting with this interface.
  • Multi Interface Test Setup - With this solution, DUTs over different interfaces can be tested simultaneously using a single MAPS™, which provides all the required functionalities over these interfaces.
  • Wrap Around Test Setup - With this solution, vendors can test their DUT by replacing all the nodes interacting with the device with appropriate MAPS™ products
