The IP Multimedia Subsystem (IMS) is an essential component of Next Generation Networks. The IMS enables cross-provider access to services via the Internet Protocol. The 3GPP and ETSI define the servers, switching and handover points, as well as the communication relationships and processes. The central signaling protocol is SIP. Other protocols are used for database access and the control of gateways and other components. The IMS standards describe security measures and concepts for ensuring quality of service. Another focus is the provision of specific services. In the course of the course, a conceptual understanding of the IP Multimedia Subsystem is built up. Through in-depth discussion of the protocols and processes used, the necessary detailed knowledge is acquired to understand and competently assess the IMS.
Several European providers have put an IP Multimedia Subsystem into service or have taken concrete steps to do so. Standardization is also more detailed in many respects than it was a few years ago. The frequently voiced accusation that SIP has no performance features is now being refuted as part of IMS standardization. There are also concrete proposals on security issues. In our course, new aspects of signaling with SIP and Diameter are discussed using the standards and concrete examples. Detailed call flows on performance features and security will also be discussed. Topics such as emergency calls, location-based services, quality of service and billing/charging will also be discussed. -

Classroom training
- Do you prefer the classic training method? A course in one of our Training Centers, with a competent trainer and the direct exchange between all course participants? Then you should book one of our classroom training dates!
-
Hybrid training
- Hybrid training means that online participants can additionally attend a classroom course. The dynamics of a real seminar are maintained, and the online participants are able to benefit from that. Online participants of a hybrid course use a collaboration platform, such as WebEx Training Center or Saba Meeting. To do this, a PC with browser and Internet access is required, as well as a headset and ideally a Web cam. In the seminar room, we use specially developed and customized audio- and video-technologies. This makes sure that the communication between all persons involved works in a convenient and fault-free way.
