5G Core Emulation and Analysis Test Solutions

GL Communications Inc is pleased to announce the latest edition of the Newsletter, which offers insight into our 5G Core Network Test solutions. This powerful solution helps network operators, equipment manufacturers, and service providers thoroughly test and analyze their 5G core networks and ensure they are functioning optimally.

5G Core Network


GL’s Message Automation Protocol Simulation (MAPS™) suite offers powerful 5G emulation and analysis capabilities, along with the ability to emulate other protocols in Time-Domain Multiplexing (CAS, SS7, ISDN, etc.) and Voice over IP (SIP, RTP, SIGTRAN, etc.) domains. The MAPS™ software suite enables rigorous testing and troubleshooting of network infrastructure, software applications, and User Equipment (UE) for compliance.

The 5G network's End-to-End architecture connects 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) to Data Server or Application Functions and EPC/IMSS core, allowing seamless interoperability.

The MAPS™ framework accurately tests the functionalities and performance of the core network and its underlying entities with multiple base stations and tens of thousands of UEs, along with 5G core elements. This unique approach enables replacement of any element in the network with the device under test, facilitating wrap-around testing.

In addition, GL’s 5G Protocol Analyzer effectively monitors 5G networks, captures, decodes, and collects statistics over the N1N2, N4, N8, N12, and N13 interfaces of the 5G network, providing valuable insights for efficient 5G network operation.
