The GSMA RCS Project is a collaborative effort - now supported by nearly 100 operators, vendors and other telecommunication companies - to facilitate the introduction of commercial, IMS based rich communication services for UMTS and CDMA mobile as well as fixed networks. RCS features are described in a series of specification release documents that cover service definition, functional description and technical realization. The latest release is Release 3, December 2009. Comprehensive specifications are available for the core features of Enhanced Address Book, Rich Call and Rich Messaging for mobile and pc clients. The project is focussing on accelerating the take-up of RCS solutions by operators, expanding the features available in RCS and testing RCS solutions.
