To help service providers make a successful transition to these new opportunities, Cisco Systems has developed an architecture called the Cisco IP Next-Generation Network (IP NGN). Cisco IP NGN helps service providers develop and plan their organizations, their specific network architectures, and business models for the future. Within the NGN arena, a new set of standards is gaining momentum. The IP Multimedia Subsystem (IMS) is an open, standardized architecture that aims to merge multimedia services across the cellular world and IP networks, using the same standard protocols for both mobile and fixed IP services. Based on Session Initiation Protocol (SIP), IMS defines standard control plane interfaces for creating new applications.
