The Session Initiation Protocol (SIP) technology is a flexible and extensible protocol for making, changing, and terminating data sessions between one or more participants. SIP has been adopted by many wireless and wireline telecommunications providers. While the basic operations of the protocol are simple and straightforward, its level of sophistication and functional richness warrant a detailed analysis. This course provides an overview of the SIP architecture, related protocols and Diameter in the context of IMS and VoLTE. The focus is to provide an introduction to the SIP architecture, SIP protocol and Diameter to understand how these protocols come together with IMS and LTE to deliver voice services. Students will then step through some key SIP and Diameter operations as they relate to delivering Voice services. The course concludes with a discussion of a Call Setup scenario to tie all the concepts together.
Learning Objectives
After completing this course, the student will be able to: • Explain the motivation for SIP for IMS and VoLTE • Describe the SIP architecture for IMS • List the key nodes and interfaces for IMS and VoLTE • Recognize how SIP interacts with other significant signaling protocols • Describe Diameter and its role in the context of IMS/VoLTE • Describe Megaco and its role in the context of IMS/VoLTE • Explain the SIP protocol and operations for session establishment and session changes • Describe key SIP operations including registration and authentication • Synthesize at a high-level the concepts of SIP and Diameter and how they apply to delivering VoLTE using IMS.
Intended Audience
This introductory course addresses the needs of technical professionals who need to understand the use of SIP and Diameter in the context of IMS and LTE to deploy VoLTE services.
