IP Multimedia Subsystems (IMS) - The Open Industry Standard Supporting the Next Generation of Converged Network Services

The next generation communications network is already taking shape, driven by the demand for new, converged services from consumers and business professionals alike. To take advantage of this opportunity, service providers are adopting new business models and moving to open standards in order to provide their customers with ubiquitous services that can be accessed by any end-user device. IP Multimedia Subsystem (IMS) is emerging as the industry standard of choice for the next generation network. IMS was initially developed by the 3GPP (3rd Generation Partnership Project) and 3GPP2 organizations, primarily as an IP core network architecture for cellular/wireless operators. Industry leaders are now turning to the standard to support converged services from all types of services providers - wireless, wireline, cable, and applications.
