The IP Multimedia Subsystem (IMS) was introduced in Release 5 of the 3GPP UMTS specifications and has been updated through successive releases of standards ever since.
UMTS and LTE are not simply mobile phone systems with ever faster data rates. They are predicated on several major changes; the predominance of data communication, the move to an all-IP structure with the consequent removal of circuit switched telephony and the need for lower end to end delay. This means that a set of functions is needed to support media conversion to other networks and, at the same time, add sophisticated charging and policy based functions. The IP Multimedia Subsystem is charged with supporting these functions. IMS requires protocols and interfaces such as SIP - Session Initiation Protocol, DIAMETER, etc to enable it to work.
This course introduces both IMS and the necessary enabling technologies for it.
The evolution of IMS through the releases of UMTS and onwards to LTE is described.
Training Course Objectives
On completing this course, you will be able to:
Understand IMS services and standards bodies
Be able to describe IMS protocols, procedures and components
Be aware of the role of SIP (Session Initiation Protocol) in IMS
Appreciate the role and use of Diameter as well as RTP
Understand IMS security, QoS and Service provision
Receive an explanation of the evolution and changes of IMS through Releases 5 to 8 (UMTS to LTE)
Who should attend
Delegates needing an in-depth understanding of IMS and its evolution
Such delegates would be employed or contracted to:
Regulators in the mobile communications industry.
This course assumes an understanding of LTE technical concepts and architecture.
Lifetime Post-Course Support
After completing this course, delegates receive lifetime post-training support from LEVER Technology Group PLC, to help them apply the technologies and skills they have learned with us, to provide career-long support, and to ensure they are better equipped for their future roles in IT and networking.
Evolution of 3GPP-specifiied Networks
Release 99 to Release 7 (UMTS) and LTE (Release 8)
