MAPS™ 5G N12 Interface Simulation

Overview

MAPS™ 5G N12 interface can emulates AUSF, within the 5G Core Network offering services to the AMF via the Nausf service based N12 interface.

MAPS™ N12 Interface Emulator supported Procedures are -

  • Nausf_UEAuthentication (Authentication and Key Agreement)
  • Authentication Result Removal with 5G AKA method

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 2G, 3G, 4G and 5G network.

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.

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/ HTTP2 protocol with JavaScript Object Notation (JSON) as the application layer serialization protocol.

Main Features

  • Emulates AUSF and AMF elements
  • Supports Authentication and Key Agreement (AKA) and Authentication Result Removal with 5G AKA method services via Nausf service based N12 interface
  • Services use REST APIs based on HTTP and JSON data format
  • Supports TLS and TCP transports
  • Supports scripted call generation and automated call reception
  • Supports customization of call flow and message templates to create valid and invalid scenarios
  • Ready-to-use scripts for quick testing
  • Provides Call Statistics and Events Status
  • Emulates Multiple Subscribers using CSV Profiles
  • Automation, Remote access, and Schedulers to run tests 24/7
