Overview

MAPS™ 5G N20 interface can emulate Access and Mobility Management Function (AMF), within the 5G Core Network offering services to Short Message Service Function (SMSF) via the service based N20 interface.

MAPS™ N20 Interface emulator supports Nudm_UEAuthentication Services : Get and ResultConfirmation operations.

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.

The product supports Mobile traffic core - GTP (ETH101) emulation for user-plane packet transmission and reception services between any two nodes in 5G network. Mobile Traffic Core - Gateway (ETH102) module allows emulation of Gateway Traffic to test media gateway telephony interfaces over IP. These modules also support generation and verification of data traffic such as Email, FTP, Web (HTTP), Video, and more.

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
