IMS Workshop
Course Duration  
3-day instructor-led training, 0900-1700

Course Overview		  
IMS is the cornerstone of the future IP based cellular networks. It was designed to support the most advanced data services from day one. IMS offers built-in mechanisms for IP-based charging (postpaid and prepaid) as well as quality of service and high level of security. The IMS framework supports: Network level, personal and group communications; Rich multimedia and IP based applications; End-to-end QoS through control plane and media plane; Reduction in deployment costs due to standard based components; Built-in connectivity to circuit-switched telephony and wireless standards. During this day we will cover IMS architecture and components as well as service flows and initial market data.

Who Should Attend?
The course is intended for operators, system integrators and vendors who wish to understand the standards and technologies behind the emerging IMS framework as the new core network. It can also be beneficial for developers exploring how to take advantage of this new architecture and what interfaces and methods are available for application development.
