Whats IMS?

IMS is a standard architecture being developed by almost all tier 1 telecom operators and their vendors. It provides a service creation and delivery platform for new session initiation protocol (SIP) based multimedia services independent of network access technology. From a technical perspective the IMS architecture is a new standard that reuses previously developed IP protocols and introduces new application servers. So what is meant by standardized? It means that functions and interfaces can be located in multiple nodes (computers), or multiple functions can exist in a single node. Several IP protocols are reused, such as SIP; Diameter for authentication, authorization and accounting; and common open policy service (COPS) for gathering usage information from routers. What is new about IMS is the many new SIP servers and the additions to existing IP interface protocols.
