A software application for emulating LTE interfaces.
Gaithersburg, MD (PRWEB) May 19, 2011
GL Communications Inc. announced today the release of its latest product LTE Protocol Simulator- a software application for emulating LTE interfaces. Disclosing the news to media, Mr. Vijay Kulkarni, CEO of the company said,” Long Term Evolution (LTE) is about a mobile technology that can change the way you work and play. It can improve or destroy your productivity. In the diagram below, some of the internals of a LTE network are shown. The user (UE) has very high speed RF connection to the nearest local tower. This high speed connection is always ON, as long as the mobile is powered up.”
He added, “LTE is an all IP infrastructure with service priority built in – audio and video are given priority. All necessities like IP address, authentication, and security are validated. Instant resources over RF (the air) and IP (internal network) are made available depending on what the user is attempting to do. Also, LTE is designed for compatibility with older 2G and 3G mobile systems.”
Mr. Kulkarni further added, “GL has released LTE Protocol Simulation for several interfaces – currently S1 – MME, and eGTP (S5/S8 and S11). Its Message Automation & Protocol Simulation (MAPS™ - LTE-S1 and LTE eGTP) is designed for LTE Testing. It can simulate eNodeB (also called Evolved NodeB), and MME (Mobility Management Entity) and other interfaces as provided in the diagram below.”
He added, “MAPS™ - LTE-S1 can act either as eNodeB or as MME and simulate the other entity. It can generate any LTE-S1 messages in an automated, interactive, and scripted fashion. Possible applications include:
•Simulate up to 500 Smartphones (UEs) powering up and down
•Authenticate and confirm security procedures
•QoS requests for greater or lesser bandwidth
•Temporary addressing management for mobility and security
LTE-S1 Testing Features
•Simulates eNodeB and MME
•Supports LTE control plane
•Generates hundreds of UE Signaling
•Generates and process S1/NAS valid and invalid messages
•Supports message templates for both S1-AP and NAS message and customization of the field values
•Allows defining variables for various fields of the selected message type
•Ready-to-use scripts for quick testing
•Supports customization of call flow and messages
•Supports scripted call generation and automated call reception
•Script based & protocol independent software architecture
•Supported on Windows® XP or higher version operating systems
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.
