 IMS Core Networks: A Dynamic Service-Based Architecture
Beyond VoIP, Push to X, Convergence, Unified Messaging, and Unified Address Books IMS is not new and it is not an application, it is the foundation for service creation architecture. IMS enables operators to quickly develop and deploy new services. Operators can no longer compete on bandwidth and are now offering unlimited voice packages both in wireless and wire-line networks. As a result, they have to devise new means of generating revenue. In 2008, large operators such as Verizon will deploy IMS networks as a means of providing unified services across their disparate access networks. Cable companies will deploy IMS to migrate their non-resilient legacy architecture to a more flexible, service-oriented architecture. This will present a huge opportunity for vendors with strong professional or managed services organization. IMS is challenging to integrate and operators are looking to partner with vendors who can easily meet this challenge. This study provides a comprehensive look at the IMS activities in wireline and wireless access networks. It offers insight into how operators are using IMS, and its role in future network migration. The report also provides market data to help operators and vendors assess the true value of IMS and to quantify the market opportunity.  What Does This Report Answer?
