IP Multimedia Subsystem,
Charles Tuyryagyenda, CEMAS Research Fellow
The Internet Protocol (IP) Multimedia Subsystem (IMS) is a core network architectural framework for delivering telephony and multimedia services. IMS was originally designed in 2005, by the third generation partnership project (3GPP) with a vision of evolving wireless mobile networks beyond GSM.
One of the main attractive features of IMS is the provision of multimedia services (voice, video, chat etc) independently from access networks (GSM, LTE, HSPA etc). This is achieved a through distinct separation of the services layer from the access network layer thus enabling opportunities for the creation of advanced multimedia services and 3rd party applications.
In order to ease the integration with the Internet, IMS utilises Internet Engineering Task Force (IETF) approved protocols wherever possible such as Session Initiation Protocol (SIP).
This talk discusses the functions of the IMS core network entities and the respective reference points that facilitate interconnection among the network functional elements.
