IMS And The Importance Of Access Network Management (2006)

By Rich Higgins, C-COR, Inc.

IP Multimedia Subsystem (IMS) is positioned to become the primary next generation IP network services architecture for broadband service providers worldwide. IMS has the potential to increase revenue opportunities by allowing greater flexibility in both services and the types of devices that consumers will use to access these services. IMS also has the potential to lower service development costs and reduce time to market.

The need for access network management both to prevent theft/abuse and ensure a quality user experience grows as more services come to depend on this shared infrastructure.

This paper will examine some of the IMS architecture/service elements and the implications of IMS for the cable access network architecture with particular emphasis on the Policy Decision Function (PDF) and access network security.
