Summary

This study examines the market for the IP Multimedia Subsystem (IMS) standard, which is increasingly gaining traction within the telecommunications industry. This traction can be seen in the large number of players that are committing to the standard. Equipment providers and operators regard IMS as the next step in next-generation network convergence that enables the new services across wireless and wireline domains as well as across operators.

This document presents a forecast and analysis of IMS in Western Europe for the 2005?2010 period. In addition, it provides an outline on how key European vendors approach IMS.

Rogier Mol, senior analyst, European VoIP Infrastructure, states that, "Despite the fact that it's still the early days for IMS and that currently few carriers have revealed their IMS plans in Europe, the promise of faster deployment of new revenue-generating services based on a standardized architecture that can be used in wireline and wireless networks across operator domains is already making IMS appear in many RFPs for network equipment."

Companies Mentioned: Alcatel; Ericsson; Siemens; Nokia; NetCentrex; Cirpack; Nortel
