RCS (Rich Communication Suite) was a join industry effort aiming to speed up the evolution of mobile phone communication towards rich communication.

The RCS initiative includes network operators, network and device vendors (Orange, Telecom Italia, Telefonica, TeliaSonera, Ericsson, Nokia Siemens Networks, Nokia, SK Telecom, Sony Ericsson and Samsung).

This service (also called Enhanced Phonebook or EAB) is the main RCS Service and could be seen as an enriched buddy list with rich presence information. It is possible to launch all other services (Image/Video Sharing, File transfer, SMS, MMS …) by selecting a contact from the phonebook.

The buddy list is expressed as XML documents and stored in various document repositories in the network where such documents can be located, accessed and manipulated (created, changed, deleted) by authorized principals. Such documents are accessed and manipulated using IETF XML Configuration Access Protocol (XCAP).
