After an initial flurry, IP Multimedia Subsystem (IMS) deployments slowed as operators realised that the technology could not address pressing issues, such as the need to deploy services quickly and inexpensively across various access networks. Despite this faltering start, IMS has attracted renewed interest during the past two years.
This Viewpoint provides:
- an analysis of the number of publically announced IMS deployments worldwide from 2005 to 2010, based on our Worldwide IMS deployments database (which is included with this Viewpoint)
- an assessment of equipment vendors’ market shares of IMS contracts
- five-year forecasts of live IMS deployments and IMS capacity in terms of subscribers
- an examination of market drivers and inhibitors, as well as the business environment
- recommendations for vendors and operators.
This will be of value to vendors that wish to size the IMS market and to operators that want to know the depth of the IMS ecosystem before committing to their own deployment.
