The architecture aims to define a model that separates the services provided by mobile (traditional cellular), fixed-line (traditional telcos), and converged service providers (cable companies and others that offer triple-play like voice, video, and data services) from the access networks used to receive those services. IP Multimedia Subsystem (IMS) is an evolving definition of an architecture that solves users' and enterprises' continuing demands and challenges.
The IP Multimedia Subsystem (IMS) Services Market is expected to register a CAGR of 16.5% over the forecast period. Still confused? Spot a mistake? Give us your feedback on this definition.IP Multimedia Subsystem Services Market Analysis It is intended to eventually replace all circuit-based technologies currently used in mobile networks, although it can easily be phased in, in a piecemeal fashion, integrating with circuit-based technologies and existing billing systems, etc. The idea behind IMS is to eventually move all voice and multimedia communication (mobile and fixed) to flexible, packet-based technologies derived from Internet protocols.
IMS is a back-end, foundational technology that enables other services, not something a user would interact with directly.įor carriers, benefits of IMS include increased flexibility for carriers to offer new 3G services, and lower costs.
Video, or any combination of these – in a highly personalized and controlled IMS is based primarily on SIP (session initiation protocol).įor users, IMS-based services enable person-to-person and person-to-contentĬommunications in a variety of modes – including voice, text, pictures and It is a core network technology, that can serve as a low-level foundation for technologies like Voice over IP (VoIP), Push-To-Talk (PTT), Push-To-View, Video Calling, and Video Sharing. IMS is a general-purpose, open industry standard for voice and multimedia communications over packet-based IP networks.
