White Paper:
Transforming Service Delivery Via IMS

As telecom networks evolve toward VoIP and other IMS/IP-based services, operators will require well-managed transition converged service solutions that protect existing revenue streams, simplify migration of services to IP-based services and provide competitive differentiators for enhanced revenue opportunities. IMS service solutions provide network operators with powerful capabilities to help them:

• Introduce new services that increase revenues and provide a unified user experience which in turn reduces customer churn.
• Retain existing revenue - existing voice service offerings are ready for the growing market of VoIP users
• Simplify service migration - IMS converged services can be delivered on true converged network platforms that allow existing services to smoothly support both VoIP and wireless networks from a single, easy-to-maintain service environment

Operators will be looking for a broad set of IMS capabilities including a converged application server, flexible service creation spanning IP and circuit networks, a next-generation real time charging solution, a flexible customer data architecture and a set of high value applications

This paper provides a brief overview on the 3rd Generation Partnership Project (3GPP) IP Multimedia Subsystem (IMS) service architecture and its various service creation capabilities.
