MAPS™ 5G N17 Interface Simulation


GL's Message Automation & Protocol Simulation (MAPS™) 5G System as a service-based architecture, includes a set of Network Functions (NFs) providing services as defined in 3GPP standards. The service-based interfaces use HTTP/2 protocol with JavaScript Object Notation (JSON) as the application layer serialization protocol.

MAPS™ 5G N17 interface can emulate Equipment Identity Register (EIR), within the 5G Core Network offering services to Access and Mobility Management Function (AMF) via the service based N17 interface.

MAPS™ N17 Interface emulator supports N5g-eir_EquipmentIdentityCheck Services procedure.

GL has enhanced its MAPS™ protocol emulation tool to emulate multi-protocol and multi-interface offering a complete range of test solutions, covering the entire 5G, 4G, 3G and 2G networks.

By mimicking real-world customer behavior in lab environments, our solutions allow mobile operators and equipment manufacturers to verify their 5G networks before deployment.

GL also provides a GUI based Multi-Protocol Analyzer for on-line capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.

Main Features

  • Emulates EIR and AMF network function
  • Supports Equipment Identity services via the N5g-eir service based N17 interface

  • Supports TLS and TCP transports
  • Supports scripted call generation and automated call reception
  • Supports customization of call flow and message templates using Script Editor
  • Ready-to-use scripts for quick testing
  • Provides Call Statistics and Events Status
  • Emulates Multiple Subscribers using CSV Profiles
