IMS in UMTS Networks *RETIRED*

UMTS (WCDMA) creates a platform to converge the different worlds of voice and data services to create a global market for mobile multimedia. This two-day course is intended for those seeking an overview of UMTS’ vision for the next generation All-IP multimedia networks known as IP Multimedia Subsystem (IMS). This course provides an overview of the various concepts used in IMS architecture, functions, components and interfaces. Enabling technologies such as SIP, MEGACO and IPv6 and the use of these technologies within the IMS architecture will be studied. A discussion of Quality of Service (QoS) follows, with a presentation of key protocols and the scenarios associated with QoS. Voice Call Continuity (VCC) between IMS and a circuit switched environment will be studied. It concludes with a brief discussion on transition from R99 to IMS.

Learning Objectives

After completing this course, the student will be able to:
• List the driving forces, requirements and goals of the UMTS Core Networks
• Describe the building blocks that will be used to construct the Release 5 IMS Core Networks
• List the functions of the UMTS Release 5 IMS architectures
• Explain the signaling and transport protocols like SIP, BICC, Megaco and RTP
• Sketch the end-to-end service establishment flows in the Release 5 IMS architecture
• Depict scenarios that illustrate interworking with the PSTN and legacy wireless networks
• Identify various services that are supported in Release 6
• Describe how Session Border Controller enables access of a common IMS network with different access technologies like CDMA 200, WiMAX etc
• Explain Voice Call Continuity (VCC) which enables an IMS subscriber on a VoIP call to continue the call into a circuit switched environment.
• Explain how functions such as mobility, roaming and call processing are carried out in the new architecture

Intended Audience

This course is intended to provide a technical overview of the UMTS IMS Core Networks. It is appropriate for all technical personnel, including those in product management, planning, architecture, design and deployment.
