IMS (IP Multimedia Subsystem) IMS (IP Multimedia Subsystem) OverviewOverview The IP Multimedia Subsystem (IMS) is an open,

standardised, configurable, next-generation multi-media architecture for mobile and fixed IP services.

IMS is emerging as the “glue” that will allow operators to create, scale and evolve converged services, quickly and cost-effectively:

Services that can straddle networks — old and new, wired and wireless, data and voice, yours and mine; Services that will blend multiple modes of communication seamlessly — text with voice, chat with mail, video with blog; Services that will be defined and delivered at a fraction the cost and the time required today.
