Message Automation & Protocol Simulation (MAPS™) Multi-Interface, Multi-Protocol Simulator - TDM, IP, 2G, 3G, 4G, 5G Overview GL's Message Automation & Protocol Simulation (MAPS™) is a protocol simulation/ emulation and conformance test tool that supports a variety of protocols such as MGCP, SIP, MEGACO, SS7, ISDN, GSM, CAS, MC- MLPPP, MAP, LTE, UMTS, SS7 SIGTRAN, ISDN SIGTRAN, SIP I, Diameter, MAP IP, 5G N1 N2, N4 and others. This protocol emulation tool covers solutions for both protocol simulation and analysis. The product also supports RTP, TDM, TRAU GSM, and Mobile traffic simulation over various network. The application includes various test plans and test cases to support the testing of real- time entities. Along with automation capability, the application gives users the unlimited ability to edit messages and control call scenarios (message sequences). "Call Scenarios" are generated through scripts. MAPS™ is designed to work on TDM interfaces as well as on the Ethernet interfaces. TDM signaling protocols such as SS7, ISDN, CAS, MC-MLPPP, MAP, IUP, CAP, INAP, GSM, and FXO/FXS operate over TDM networks, whereas SIP, MEGACO, and MGCP operate over IP networks. MAPS™ supports 3G & 4G mobile protocol simulation such as LTE (S1, eGTP) interfaces, LTE Diameter [S6a, S6d, S13, Cx/Dx, Gx, Rx, SLg, SLh], INAP IP (ANSI, ITU), CAP IP (ANSI, ITU), GSM A over IP, SKINNY, MAP IP, BICC IP, GPRS, and UMTS (IuCS, IuPS, IuH) over IP. MAPS™ architecture supports both Binary and Text Based Protocol Simulation. MAPS™ also supports Location Services (LCS) simulation for positioning mobile devices. Simulates SLg, SLh interfaces (GMLC, MME, HSS), Lg, Lh interfaces (GMLC, MSC, SGSN, HLR), SLs interface (MME, E-SMLC) and Lb interface (MME, SMLC) and interfaces implementing positioning functionality in a cellular network.
