The search is on within the Service Provider community for a solution that can address the challenge of and provide the opportunity for leveraging existing, proven applications and network assets across IMS infrastructure. This white paper examines the state of IMS and how the Service Broker can enable a cost effective, future proof answer to the question of how best to navigate the transition to IMS. Service Providers face a number of issues as they continue to struggle with ways to enable efficient, effective and timely application introduction. The challenge is not a new one. Tried and true application connectivity models for TDM/IN networks tend to utilize a “siloed” approach in which applications are individually configured and connected into networks. This can be seen in standalone voice applications as well as within large SCP based IN services. While the approach worked it came with a variety of issues (or challenges) for the Service Providers as they looked to enhance or adapt the application to the underlying network change and evolution.
