GL Communications Inc. addressed the press regarding their solutions for emulating various telecom protocols (VoIP, TDM, Analog, Wireless) within a single framework – Message Automation and Protocol Simulation. The application includes various test cases to confirm the functionality of telecom infrastructure.

GL’s comprehensive Signaling and Traffic Emulation test equipment suite, commonly referred to as Message Automation and Protocol Simulation (MAPS), provides a programmable, highly flexible, script-based, multi-protocol, multi-interface emulation framework and makes it easy to perform cross-domain testing and transition tests to new technologies such as 5G. The core network and all its underlying entities can be accurately simulated for functionalities and performance.

The test suite can work with GL’s High-Density Call Generator for IP & Wireless Networks, a specialized hardware platform for generating tens of thousands of simultaneous calls. Using a stack of such servers, a larger test system with up to 100,000 simultaneous calls is achievable for enterprise testing.

MAPS 5G Emulator can emulate multiple UEs and interfaces such as N1, N2, N4, N8, N10, N11, N12, N13, N17, N21, N29, and N51 on the 5G core network.

MAPS 4G Emulator supports emulation of various interfaces of LTE (S1-u, S1-MME, S3, S4, S5/S8, S6a, S11, S13, SLs), and IMS (Diameter) (Cx/Dx, Mw, Mi) interfaces.

MAPS 3G Emulator tests all 3G interfaces such as IuCS, IuPS, IuH, IuPC, and Gn Gp. MAPS UMTS Lg, Lh interface emulator supports necessary protocols in UMTS Location Service (LCS) architecture for emulating network elements over Lg (MSC/VLR, SGSN, GMLC), Lh (HLR, GMLC), IuPC (SAS and RNC) interfaces.

MAPS 2G Emulator emulates various interfaces of 2G (GSM, GPRS, MAP, CAP, INAP, BICCIP, and GPRS) elements such as SGSN, and GGSN to support mobile call and traffic emulation.
