Intel and telcos left in virtual RAN limbo by rise of AI RAN
A multitude of general-purpose and specialist silicon options now confronts the world's 5G community, while Intel's future in telecom remains uncertain.
3GPP-compliant IP multimedia subsystem (IMS) uses IP and SIP technologies to enable integrated multimedia services
February 23, 2004
TOKYO -- NEC Corporation announced the launch of their 3GPP (3rd generation Partnership Project) compliant IMS (IP Multimedia Subsystem). The IMS platform enables new types of multimedia services on IP (packet) networks by utilizing IP and SIP (Session Initiation Protocol) technologies. NEC's platform brings voice and data services together, allowing operators to generate new revenues by developing and deploying new varieties of integrated solutions. NEC's IMS and SIP solutions are now trialing with a number of mobile operators around the world as a core solution for the next generation of ubiquitous mobile multimedia services.
NEC's IMS service line-up shows the potential of SIP services to increase the ARPU (Average Revenue Per User) of mobile operators, while tackling serious issues such as decreasing churn rates. SIP enables 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. With NEC's SIP gateways, mobile operators can deploy IMS services much more broadly across a combination of SIP and non-SIP terminals. In this way, operators can offer their customers a smoother service migration to IMS services and integrate these services with the existing service portfolio.
By leveraging NEC's experience of building network infrastructure and service solutions, NEC's IMS solution has, to the advantages of 3GPP compliance, added rich application services and a seamless service offering to mobile terminals. All of this is realized through a combination of NEC's own middleware and UNIX servers that distills high performance from a cost-effective, carrier-grade platform. NEC's IMS is available with both IPv6 and IPv4 address handling.
