IMS Solution for Mobile Service Providers
The IP Multimedia Subsystem (IMS) is a framework for providing much more than VoIP. It provides real multimedia services, combining text, images and video. It is the foundation for a world where services and transport are IP-based. IMS manages all the various mobile access networks (3G; 2,5G; EDGE; Wifi; WiMAX), but now has been extended to also support the fixed access methods such as xDSL, while services are access agnostic and can be common to the fixed and mobile world. It is THE foundation for fixed and mobile convergence.
