Lucent Introduces IP Multimedia Subsystem for 3G Networks

Lucent Technologies unveiled its "Accelerate" IMS (IP Multimedia Subsystem) for supporting VoIP and multimedia services over 3G networks.



The Accelerate IMS is based on IP core networking standards that have been developed by the 3G Partnership Project (3GPP) and 3GPP2. At the heart of the Accelerate) IMS solution is the Lucent Softswitch, a next-generation switching platform that manages voice and multimedia communications on IP networks. The Accelerate IMS solution also incorporates the Cisco MGX 8000 Series Media Gateways, which are offered as part of a joint solution with Cisco Systems. Lucent also is working with IBM to leverage and integrate IBM WebSphere infrastructure and software as part of the Accelerate IMS solution and incorporating IBM eServer BladeCenter and IBM Service Provider Delivery Environment (SPDE) framework and applications.



Another central element of the Accelerate IMS architecture is Lucent's Super Distributed Home Location Register (S-DHLR), which serves as the Home Subscriber Server (HSS) for the IMS, maintaining information such as subscriber profiles and user location on mobile networks. The S-DHLR enables the creation of a single subscriber profile for each customer and all of the services they use, in contrast to the traditional method of maintaining individual subscriber databases for each service.



Lucent is also developing a series of new services targeted at the consumer market. These include the "MiRingBack/MiVideoPortal" service, which allows end-users to personalize an audio or video greeting that is played on a calling party's mobile phone or other device; "iLocator", which is a service that tracks people, events or businesses and displays their positions on a map; and "AnyPath Mobile Messaging", which allows subscribers to have their voice mail messages automatically downloaded directly to their MMS, BREW, or J2ME enabled devices. http://www.lucent.com
