IP MULTIMEDIA SUBSYSTEM(IMS)

IP Multimedia Subsystem (IMS) solution enables service providers to dramatically transform both the end user communications experience and their own business models. IMS is a standardized service delivery architecture based on the Session Initiation Protocol (SIP) that equips service providers to deliver a far richer service experience via a fully converged network across both wireline and wireless access.
Our experience and leadership in the following key areas will enable service providers and cable operators to successfully deploy IMS services:

SIP Application - Developing and deploying real-time multimedia applications
IMS Solution Openess - Nortel's Open SIP Interoperability program opens our solution to developers, partners and application providers, securely and reliably
IMS Control Architecture - Nortel has one of the industry's most advanced IMS Session and Service Control architecture - the essential ingredient to unleash the true power of IMS; and
IMS Deployment Flexibility - Providing cost-effective alternatives to trial and deploy IMS empowered services.
