The IMS (IP Multimedia Subsystem) is an architectural framework for delivering Internet Protocol (IP) multimedia services. Originally designed by the 3GPP as a part of the vision for evolving mobile networks beyond GSM, this vision was later updated by 3GPP, 3GPP2 and TISPAN by requiring support of networks other than GPRS, such as Wireless LAN, CDMA2000 and fixed line. IMS uses IETF protocols wherever possible, e.g. Session Initiation Protocol (SIP).
IEEE Communications Society has chose IMS as this month’s featured technology. Papers discussing IMS are provided free this month for the visitors of IEEE Comsoc. Those include the IMS architecture and strategy; its usage in 3G, 4G, and IPTV; and the potential applications to develop over it.View Free Paper
