IMS

Eager to increase revenue, service providers are looking to new value-added services to attract and retain customers and increase revenue. Because the success of particular services is difficult to predict, a dynamic architecture is needed to allow service providers to offer promising new services quickly, add resources for successful services as demand increases (sometimes very rapidly), and downplay or remove unsuccessful services easily.

The IP Multimedia Subsystem (IMS), a modular standards-based service platform that uses the Internet Protocol (IP) and the Session Initiation Protocol (SIP), appears poised to provide precisely the kind of dynamic architecture that service providers need.

During the past few months, Dialogic’s technologists have published several papers on various aspects of IMS:

• Addressing Video Processing Challenges with the IP Multimedia Subsystem: Performance, Architecture, and Network Topologies discusses how the IMS network can be used to convert video content so that it is accessible to any user, and how network-based processing techniques could be applied to a wide variety of applications.
• Security Applications and Technologies for IP Communications Networks briefly highlights past network security issues, examines the shortcomings of existing security architectures that do not address the future's security requirements, and presents possible approaches that can solve them.
• Bringing Video to the Mobile Handheld Market: Background, Challenges, and Potential presents a brief background on the evolution of the mobile wireless network, discusses some of the challenges to be overcome to make video to the mobile handheld practical, not only as a source of entertainment but also as an enhanced collaborative business-communication tool, and presents some scenarios on the potential for video to the mobile handheld market.
