Gaithersburg, Maryland, USA - Aug 5, 2022 - GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their 5G Core Network Test solutions.

Overview

GL’s Message Automation Protocol Simulation (MAPS™) software emulation suite can emulate a multitude of different protocols spanning Time-Domain Multiplexing (CAS, SS7, ISDN, etc.), Voice over IP (SIP, RTP, SIGTRAN, etc.), and Wireless (5G, 4G LTE, 3G) domains. It can be used to test and troubleshoot network infrastructure, software applications and User Equipment (UE) and ensure compliance.

“The End-to-End 5G network comprises the 5G Access Network (gNB), Access and Mobility Management Function (AMF), Authentication Server Function (AUSF), Network Slice Selection Function (NSSF), Unified Data Management (UDM), Session Management Function (SMF), Equipment Identity Register (EIR), Short Message Service Function (SMSF), Network Exposure Function (NEF), and User Plane Function (UPF) connected to Data Server or Application Functions and EPC/IMSS core for interoperability. The core network and all its underlying entities can be accurately tested for functionalities and performance using the MAPS™ framework”, said Vijay Kulkarni, CEO of GL Communications.

The MAPS™ application provides fully configurable multiple base stations with tens of thousands of UEs along with 5G core elements. This approach allows to replace any element in the network with the device under test and carry out wrap-around testing.
