The 3G IP Multimedia Subsystem (IMS)
Merging the Internet and the Cellular Worlds
Gonzalo Camarillo, Miguel A. Garcia-Martin
Résumé
WCDMA, CDMA2000 and UMTS were developed with a primary goal in mind: delivering new services to the end users, and thus, new revenue opportunities for the operators. IMS is seen as one of the key multimedia enablers towards providing such services and, therefore, a thorough knowledge of IMS equates to an understanding of why we need 3G and how it will provide enriched end user services. With the standardisation of the first phase of IMS completed in June 2003, the first 3G networks supporting IMS are expected to be commercially deployed during 2004.
The 3G IP Multimedia Subsystem:
- Covers the hot topic of IMS which will provide multimedia Internet services to mobile wireless users
- Presents a high level overview of IMS
- Explains how the IMS system which covers all the existing capabilities of voice, data and messaging, will also facilitate new media services such as video or high quality audio to be set up between two or more users
- Includes extensive figures showing network architectures, message flows, protocol operations and photographs of 3G equipment
Authored by two systems experts based at Ericsson this title will have instant appeal to a wide range of readers, from mobile phone vendors and network manufactures to mobile operators, ISPs and third party service providers.
