Course 519: IMS Training Course - IP Multimedia Subsystem - TONEX.com

TONEX IP-Multimedia Subsystem (IMS) Training course provides an advanced technical overview of IMS, SIP and Diameter.

In this course we will discuss various advanced concepts that are integral to the development of IMS,  LTE, IP networks, security, SIP and Diameter.

The IP-Multimedia Subsystem (IMS) defines the functional architecture and requirements  for a managed IP-based network. It is an open, standards-based network that delivers integrated multimedia services to service providers.

After completing this course, students will be able to:

• Understand concepts behind All-IP Multimedia Networks
• Explain IMS services
• Understand IMS architecture
• Explain IMS reference architecture and interfaces
• Understand IMS session control, connection control and applications services
• Explore SIP and SDP extensions used in IMS
• Understand IMS Security and QoS
• Relate to IMS in the context of UMTS/HSPA+, LTE, TISPAN,, FMC, and CableLabs Packetcable
