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
  • 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
  • Supported on Windows XP or higher version operating systems
