IMS/RCS

For a long time, IP Multimedia Subsystem (IMS) was nothing more than just a revolutionary idea to move all existing teleservices, including telephony to the PS domain of the mobile network and to create a vast variety of brand new teleservices totally based on end-to-end IP connectivity. Today, thanks to Rich Communication Suite-enhanced (RCS-e) initiative, there is a clear path and agreement on how to turn IMS into practice. RCS-e ensures that the same initial subset of IMS services will be introduced by all operators, infrastructure and terminal vendors and will work smoothly also in inter-operator scenarios. The course explains RCS-e services, underpaying IMS architecture and basic procedures and their impact on existing operator infrastructure.

Since the first operators are already running RCS-e services, it is time to prepare for the next step in RCS evolution - RCS 5. RCS-e has not introduced any new revolutionary services, all RCS-e’s services were available much earlier from Over-The-Top (OTT) providers. The role of the RCS-e, was rather to create basis architecture and interworking procedures, that could be used to keep those services under control of a large number of independent cellular operators. RCS 5 is required to take full advantage of the IMS based system, introduced by the operator due to the launch of RCS-e and/or VoLTE services. At the same time the variety and quality of the RCS 5 services will allow mobile operators RCS5 reach significant advantage over OTT providers. The course explains RCS 5 services, underpaying IMS architecture and basic procedures and their impact on existing operator infrastructure.

For a long time, IP Multimedia Subsystem (IMS) was nothing more than just a revolutionary idea to move all existing teleservices, including telephony to the PS domain of the mobile network and to create a vast variety of brand new 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 the same initial subset of IMS services will be introduced by all operators, infrastructure and terminal vendors and will work smoothly also in inter-operator scenarios. The course explains IMS architecture, addressing, signalling procedures and services paying a special attention to the solutions selected by GSMA RCS Releases 1, 2 and RCS-e including details of inter-operator IPX procedures.
 
 

New EPC (Evolved Packet Core) call control is based on SIP (Session Initiation Protocol) and SDP (Session Description Protocol). “SIP for IMS” course focuses on signalling in IMS network. During the course registering and services request voice and video call, sending pictures, sharing pictures, short messages and chats are presented in details.
