The 3g Ip Multimedia Subsystem: Merging The Internet And The Cellular Worlds

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.
