Description: The purpose of this course is to provide an understanding of the signaling protocols used in the IP Multi-media Subsystem (IMS) to support voice and other services. The course will give you the knowledge to understand the evolving telecommunications network including the IMS. IMS is an architecture that enables network operators to offer their subscribers multimedia services based on and built upon Internet applications, services and protocols. This course covers the basic terms and concepts and explains IP (Internet Protocol) architectures and protocols that are being used to implement VoLTE in the IMS.

What You Will Learn: This course will examine the key concepts, terms and protocols of the IMS. The course provides an understanding of the primary protocols, SIP and Diameter and message flows used for VoLTE and other services.

Who Will Benefit From This Course: This course is designed for individuals responsible for or involved with network planning, interconnection, technical support or network operations.
