GL Announces Diameter Protocol Emulator for LTE
Gaithersburg, Maryland (PRWEB) June 26, 2012
GL Communications Inc. announced today the release of its latest product MAPS™ Diameter Protocol Emulator – Scripted LTE Diameter S6a, S6d, Cx, Dx, Gx, and Rx Interfaces Emulation.
Speaking to reporters, Mr. Karthik Ramalingam, Manager of Product Development, said, “The Diameter protocol is intended to provide a framework for Authentication, Authorization and Accounting (AAA) for applications such as network access, roaming, and IP mobility. AAA protocols are used to determine whether the user is allowed to connect to the network (Authentication) and use a particular service (Authorization). It is also used to track network resources used by end-user for accurate billing (Accounting).
AAA protocols such as TACACS and RADIUS were initially deployed to provide dial-up PPP and terminal server access. Over time, with the growth of the Internet and the introduction of new access technologies put new demands on AAA protocols, and as a result Diameter is a considerably more sophisticated protocol than RADIUS.”
He added, “Diameter protocol has been chosen as the AAA protocol in all next generation fixed and mobile IP- based networks (IMS, LTE). It is designed to support data, services, and applications with extreme flexibility and is expected to replace all legacy protocols such as MAP, LDAP, Radius, and others.
GL’s general-purpose platform for emulation of protocols is Message Automation & Protocol Simulation (MAPS™). Recently Diameter protocol for has been added to its wide range of emulation support. The MAPS™ Diameter gives the users the unlimited ability to edit S6a, S6d, Cx, Dx, Gx, and Rx interface messages to support various procedures such as Location Management, Subscriber Data Handling, Authentication, Fault Recovery, and Notification procedures over S6a interface and AA-Request/Answer, Re-Auth-Request/Answer, Abort-Session-Request/Answer, and Session-Termination-Request/Answer procedure over Rx interface.”
·Emulator can be configured as MME, HSS, PCRF, AF, CSCF, SGSN, and PDN GW entities to emulate S6a, S6d, Cx, Dx, Gx and Rx interfaces.
·User-friendly GUI for generating hundreds of UE Signaling (Load Testing)
·Ready scripts for Location Management, Subscriber Data Handling, Authentication, Fault Recovery, and Notification procedures over S6a interface. AA-Request/Answer, Re-Auth-Request/Answer, Abort-Session-Request/Answer, and Session-Termination-Request/Answer procedure over Rx interface
·Impairments can be applied to messages to simulate error conditions.
·Supports customization of call flows and message templates using Script editor and Message editor
·Ready-to-use scripts for quick testing
·Supports scripted call generation and automated call reception
·Provides protocol trace with full message decoding, and graphical ladder diagrams of call flow with time stamp
·Script based & protocol independent software architecture
·Provides call statistics and associated captured events and error events during call simulation
About GL Communications Inc.,
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL’s test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.
GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.
GL’s Voice Quality Testing (VQT) product line complements all of GL’s products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL’s VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.
GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GL’s compliance testing per G.168. G.167, and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.
GL’s wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.
GL’s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.
GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
