IMS - IPTV moving together

摘要

The IP multimedia Subsystem (IMS) is a network functional architecture that is seen as a promising solution for facilitating multimedia service creation and deployment, as well as supporting interoperability and network convergence. IMS allows network operators to play a central role in traffic distribution, therefore being more than “bit pipes”. The move towards all IP architecture for service delivery appears to be a string trend. In this context, customers seem to desire an access to personalized interactive, multimedia services, on any device and anywhere. This trend introduces new requirements for network infrastructures. The IMS is seen as a promising solution for fulfilling these expectations.
