NEC Announces 3GPP IP Multimedia Subsystem (IMS)

NEC introduced its 3GPP (3rd generation Partnership Project) compliant IMS (IP Multimedia Subsystem). enables new types of multimedia services on IP (packet) networks by utilizing IP and SIP. The platform could be used for SIP services such as Presence (a mechanism for sharing users' status and context information over the mobile network), PoC (Push-to Talk over Cellular - a real-time half-duplex voice service), instant messaging and group chat. A key element of the NEC IMS product strategy is the SIP gateways that allow non-SIP mobile terminals to use IMS services, providing a smoother service migration to IMS services for mobile operators.



NEC said its IMS and SIP solutions are now trialing with a number of mobile operators. http://www.nec.com
