IP Multimedia Subsystem (IMS) represents a
framework for development, deployment, and operation of various
applications for support of any-network, any-device, and service
provider usage. IMS consists of standards based technologies,
architecture, and network elements that bring telephony type control to
Internet based applications.
The long-term promise of IMS is that it will dramatically simplify many operations include key OSS/BSS functions such as provisioning, administration, billing, and others. However, the more near term implementations of IMS fall short of this ultimate vision. Applications are initially deployed in a silo fashion as a prerequisite to a more integrated network realization.
This research evaluates the major challenges in implementing and operating a multi-application IMS environment. The research presents solutions including scenario analysis of different feature/application combinations. This report also addresses the business case for deploying mitigation solutions to enable more streamlined multi-application service environments.
