MAPS™ Diameter Protocol Emulator

Overview

MAPS™ Diameter can simulate S6a, S6d, S13, Cx/Dx, Gx, Rx, Sh, and Gy/Ro interfaces and test IMS network elements such as the MME (Mobility Management Entity), HSS (Home Subscriber Server), AF (Application Function), PCRF (Policy and Charging Rules Function), CSCF (Call Session Control Function), SGSN (Serving GPRS Support Node), PCEF (Policy and Charging Enforcement Function), EIR (Equipment Identity Register), PDN GW (Packet Data Network Gateway), AS (Application Server), CTF (Charging Trigger Function), and OCS (Online Charging System).

The application is available as –

• MAPS™ Diameter (Item # PKS139) for S6a, S6d, S13, Cx, Dx, Gx, Rx, Sh, and Gy/Ro interfaces

Other interfaces such as Rf, Dh,  Gq, Zh, Zn, Wa, Wd, Wx, Wm, Wg, Pr will also be supported by the application in near future.

The application supports both SCTP (Stream Control Transmission) and TCP (Transmission Control Protocol) transport protocol layers for PSTN signalling messages over IP networks. MAPS™ Diameter also supports TCP/TLS (Transport Layer Security) for the secured information transfer.

• MAPS™ Diameter Emulator includes powerful utilities like Message Editor, Script Editor, and Profile Editor which allow new scenarios to be created or existing scenarios to be modified using Diameter messages and parameters. “Message sequences” are generated through scripts. “Messages” are created using message templates. These features give the users the unlimited ability to edit messages on supported interfaces to support various procedures listed below.

MAPS™ also supports an End-to-End 4G LTE Communications Network Lab with all components to simulate E-UTRAN, EPC (Evolved Packet Core) and IMS, allowing complete testing of the LTE-IMS network.

Possible applications include:

Simulate up to thousands of Smartphones (UEs) powering up and down
Authenticate and confirm security procedures
Temporary addressing management for mobility and security

GL also provides a GUI based All-IP PacketScan Analyzer for on-line capture and decode of the Diameter signaling in real-time both during tests and as a stand-alone tracer for live systems
