This article describes the latest buzzword in telecommunication, referring to the Internet protocol (IP) Multimedia Subsystem (IMS). IMS is an architecture that defines how IP networks should handle voice calls and data sessions. It essentially takes the place of the control infrastructure in the traditional circuit-switched telephone network, with the key difference that it separates services from the underlying networks that carry them. This way, services such as text messaging, voice mail, and file sharing can reside on application servers anywhere and be delivered by multiple wired and wireless service providers.
