MAPS™ 5G N29 Interface Emulation

Overview

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 N29 interface can emulate Network Exposure Function (NEF), within the 5G Core Network offering services to Session Management Function (SMF) via the service-based N29 interface. MAPS™ 5G N29 supports Nsmf_EventExposure service 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 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.

Main Features
