VoLTE with IMS Focus

Course Description

Mobile Operators are looking ahead towards future architecture, standards, technology and applications for the Core Networks.

Deploying LTE radio access technology, Voice over Long Term Evolution (VoLTE) which utilizes IMS technology is recognized as the industry-agreed progression of voice services.

The VoLTE scheme was devised as a result of operators seeking a standardized system for transferring traffic for voice over LTE.

VoLTE facilitates far richer multi-media voice services, increasing the service quality delivered to consumers.

The training “VoLTE with IMS Focus” is high-lighting coming technologies, systems and platforms. Already existing and implemented legacy systems will not be particularly focused on rather more briefly discussed and mentioned in order to be able to present the new technologies in a well-established and understood context.

The below listed topics will be discussed and analyzed as they emerge during the course of the training.
