IMS Technology
Technologia IMS – architektura i procedury
This training provides a comprehensive survey of IMS with the focus on its architecture and key procedures. The presentation of signaling issues is complemented with description of major protocols including SIP, H.323/MEGACO, and DIAMETER. Finally, this course also introduces the concept of RCS and explains its relation to IMS.
Target Audience
Those who seek for a more in -depth understanding of IMS concept and the way it provides advanced IP based services.
Prerequisites
Prior knowledge of IP based signaling protocols wil l be advantageous when attending this training.
