GL Communications, Inc., a supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks, has launched its Long Term Evolution (LTE) Protocol Simulator. The LTE protocol standard provides users with enhanced mobile Internet access.

In a press release, Vijay Kulkarni, the company’s chief executive officer, 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.”

Kulkarni clarified that LTE is an all IP infrastructure with service priority built in – audio and video are given priority and all necessities like IP address, authentication, and security are validated.

“Instant resources over RF and IP 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," Kulkarni said.

According to Kulkarni, “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.”

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; and temporary addressing management for mobility and security.

Key features of LTE-S1 Testing includes: simulates eNodeB and MME; supports LTE control plane; generates hundreds of UE Signaling; handles retransmissions; 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; and supported on Windows XP or higher version operating systems.

In February 2010, the company released its PacketScanWeb software, a real-time network monitoring system for VoIP networks. Last month, the company launched its enhanced RTP ToolBox software, a perfect tool to test, simulate and monitor voice traffic carried by RTP & RTCP Packets.
