Course Code: MB1402
This course provides an understanding of the IP Multimedia Subsystem’s (IMS) role in Next Generation Networking. It provides a detailed description of the IMS architecture including security, charging and Policy and Charging Control (PCC). Additionally it identifies the main protocols associated with IMS including SIP, Diameter and SDP and analyzes their role in the IMS registration and session control procedures. It also provides a brief look at some of the applications enabled by the IMS.
Those requiring a full understanding of the architecture, interfaces and procedures of the IMS.
An understanding of SIP and the packet-switched domains in LTE, GPRS and UMTS networks and their functionality is an advantage.
