This course has been designed to give delegates a solid foundational understanding of the IP Multimedia Subsystem’s (IMS) role in Next Generation Networking.
It provides an overview description of the IMS architecture including security, charging and Policy and Charging Control (PCC). Additionally it identifies the main protocols associated with the IMS and analyzes their role in IMS registration and session control procedures. It also provides a brief look at some of the applications enabled by the IMS.
This course is an ideal introduction to the IMS for those who do not require the detail covered in Wray Castle’s 3-day IMS and SIP course.
Who would benefit
This session is for those aiming to better understand the architecture and operation of the IMS, potentially in relation to VoLTE, as well as those looking for an introduction to SIP.
An understanding of packet switched domains in LTE, GPRS and UMTS networks and their functionality is an advantage.
