Overview

IP Multimedia Subsystem (IMS) Status Report: Emerging from the Trough of Disillusionment provides a valuable independent IMS status report that can help all in the industry have a clear view on its current status and the likely paths operators will take in the evolution of their networks.

Report Structure:

This report provides an independent and quantified view of what is happening in the industry with IMS (IP Multimedia Subsystem), through the presentation of results from an industry-wide survey that encompasses 137 interviews (101 of with network operators). The report also includes operator and supplier case studies, presenting a factual based current state of the market, without the hype and marketing spin that has frustrated many people on this topic. These two objectives are reflected in the two main sections of this report: Market Survey Results and Case Studies which include Verizon, China Mobile, and Vodafone Spain.

Key Report Findings:

• IMS remains niche, with only 8% of those operators surveyed deploying IMS. (Note, none of those operators have completed the conversion of their network, all considered it a 5-7 year process) Another 12% are in an extended field trial, which is characterized by services being launched on the IMS core, with in some cases paying customers; but a decision has not yet been made to commit to service migration onto the IMS core.
• IMS does not appear to be entering a period of rapid adoption, rather a linear growth in initial adoption over the next 5 years, with by 2014 about 32% of operators commencing an IMS deployment.
• Regionally, NAR (North America Region) provides the bulk of the growth in years 2010 and 2011, while EMEA (Europe Middle East and Africa) and APAC (Asia Pacific) regions provide the bulk of growth in later years.
• Lack of business case, lack of standards compliance and BOSS (Business and Operational Support System) integration were the top three barriers to adoption as identified by operators.
