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.
