IP Multimedia Subsystem (IMS)
Description Objectives
The IP Multi-Media Subsystem (IMS) is an IP multimedia and telephony core network. It is defined by 3GPP and 3GPP2 standards and organizations based on IETF Internet protocols. IMS is access independent as it supports IP to IP session over wireline IP, 802.11, 802.15, WiMAX, CDMA, GSM/EDGE/UMTS and other packet data
applications. IMS permits and enhances real time, multimedia mobile services such as rich voice, video telephony, messaging, conferencing and push services by responding to the emerging trend to move toward a common, standardized subsystem. As data services proliferate and the value chain expands, current vertical application platforms are proving
insufficient to meet operator needs. IMS represents a standardized, reusable platform providing a better
way to experiment with, deploy, integrate, and expand consumer and enterprise voice and data services. This course provides an advanced technical overview of IMS. In this course we will discuss various advanced
concepts that are integral to the development of IMS and all IP networks.
After completing this course, students will be able to:
Understand concepts behind All-IP Multimedia Networks
Understand IMS architecture
Explain IMS reference architecture
Understand IMS session control and
connection control
Explore SIP and SDP extensions used in IMS
Explain IMS services
Understand IMS Security and QoS
Who Should Attend
This course is designed for strategic or technical
managers, consultants, communications professionals, software engineers, system engineers, network professionals, marketing and sales professional, IT professionals, and others who plan on using, evaluating or working with IMS.
