The IP Multimedia Subsystem (IMS) is an access-independent service control architecture that enables multimedia services to end users via Internet-based protocols. Expertise on IMS is essential for communication professionals to successfully develop and deploy new multimedia services that are IMS-based. This course investigates the IMS architecture including functions of nodes, key protocols and end-to-end operations for services using IMS. Enabling technologies and protocols such as SIP, Megaco, RTP and the use of these technologies within the IMS architecture are explored. Service continuity, interconnection, and current policy control are discussed. (Please note that this course does not cover any specific access technology.)
Learning Objectives
After completing this course, the student will be able to: • List the motivation, benefits and challenges associated with IMS • Sketch IMS network architecture • List the functions of the key components in IMS • Explain functions of key protocols such as SIP, Megaco, and RTP • Describe basic IMS operations • Explain how IMS enables dynamic Quality of Service (QoS) • Explain how IMS provides a service delivery platform • Discuss the IMS security architecture • Describe the IMS interconnection strategy • Explain how IMS is being used to provide service continuity between different access networks • Depict scenarios that illustrate interworking with the PSTN • Sketch the IMS charging architecture
Intended Audience
This course is intended to provide a technical overview of the IMS. It is appropriate for all technical personnel as well as those in product management, technical sales, planning, architecture, design, deployment and support.
