Abstract:
IP Multimedia Subsystem (IMS) is a generic architecture for offering multimedia and voice over IP services, defined by 3rd Generation Partnership Project (3GPP). IMS is access independent as it supports multiple access types including GSM, WCDMA, CDMA2000, WLAN, Wire line broadband and other packet data applications. Existing phone systems (both packet-switched and circuit-switched) are supported. IMS will make Internet technologies, such as web browsing, e-mail, instant messaging and video conferencing available to everyone from any location. It is also intended to allow operators to introduce new services, such as web browsing, WAP and MMS, at the top level of their packet-switched networks.
