Voice Over LTE (VoLTE) & IMS

( Duration: 5 Days )

In Voice Over LTE (VoLTE) & IMS training course, you will learn about VoLTE, IMS, and the SIP protocol. This course thoroughly covers call flow through the EU-TRAN, the EPC, and into the IMS core. This course also covers enough of other technologies like Diameter and DNS, providing them with a clear understanding of the complete picture.

By attending Voice Over LTE (VoLTE) & IMS workshop, delegates will learn:

  • IMS architecture
  • IMS and the DNS
  • IMS access using VoLTE
  • LTE E-UTRAN

  • Basic undertanding of GSM Core network
  • Understanding of Packet core elements
  • Aware of LTE basics

This Voice Over LTE (VoLTE) & IMS class is intended for:

  • Individuals who need to understand how LTE networks carry voice and other real time services
  • Anyone who works on a narrow part of 4G networks that needs to understand what the surrounding components do
