RCS Technology

Technologia GSMA Rich Communication Suite

For a long time, IP Multimedia Subsystem (IMS) was nothing more than just a revolutionary idea to move all teleservices totally based on end -to-end IP connectivity. Today, thanks to GSMA Rich Communication Suite (RCS) initiative, there is a clear path and agreement on how to turn IMS into practice. RCS ensures that th e same initial subset of IMS services will be introduced by all operators, infrastructure and terminal vendors and will work smoothly a lso in inter-operator scenarios. The course explains services selected by GSMA RCS Releases 1 to 5 together with their technical realizations.

Target Audience

The course is intended for technical mobile network staff and their manageme nt who plan to or already work on in troducing IMS/RCS/RCSe services.


Prior to attending this event, the participants should already have an understanding of the IMS principles and a basic knowledge on architecture of telecommunication network concepts.
