5G N20 Interface Emulation
MAPS™ 5G-N20 can emulate and test Access and Mobility Management Function (AMF) and Short Message Service Function (SMSF) entities in 5G Core Network (5GC) elements via the service-based N20 interface.Brochure
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.
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.

5G N20 Interface Procedure
In 5G N20 interface, MAPS™ acts as either AMF to test SMSF or SMSF to test AMF emulating the procedure Nsmsf_SMService Operation.
Registration procedure using Activate service operation Services
The below figures depict the Call Generation and Reception of 5G N20 interface between AMF and SMSF.
Please Note: The XX in the Item No. refers to the hardware platform, listed at the bottom of the Buyer's Guide, which the software will be running on. Therefore, XX can either be ETA or EEA (Octal/Quad Boards), PTA or PEA (tProbe Units), UTA or UEA (USB Units), HUT or HUE (Universal Cards), and HDT or HDE (HD cards) depending upon the hardware.
