The Internet Multimedia
Subsystem
The Internet Multimedia Subsystem (IMS), the Third-Generation
Partnership Project’s (3GPP) next-generation wireless/wireline
communication services reference architecture, is a highly
visible example of how SIP is enabling new services. IMS is a
standard architecture for telecom operators to provide next-
generation mobile and fixed multimedia services. It uses a
VoIP implementation based on a 3GPP standardized imple-
mentation of SIP, all running over IP. IMS will not only provide
new services but all the services that the Internet provides.
Users will be able to access their services when roaming as
well as from their home networks.
