What is Rich Communication Services (RCS)?
It is a communication protocol between mobile telephone carriers and between phone and carrier, aiming at replacing SMS messages with a text-message system that is richer, provides phonebook polling (for service discovery), and can transmit in-call multimedia.
It is also marketed as Advanced Messaging, Advanced Communications.
History of RCS
- The Rich Communication Suite industry initiative was formed by a group of industry promoters in 2007. In February 2008 the GSM Association officially became the project 'home' of RCS and an RCS steering committee was established by the organisation.
- The scope of the steering committee's work was to entail the definition, testing, and integration of the services in the application suite known as RCS. Three years later, the RCS project released a new specification – RCS-e (e = 'enhanced'), which included various iterations of the original RCS specifications. The GSMA program is now called Rich Communication Services.
- The GSMA published the Universal Profile in November 2016.[10] The Universal Profile is a globally agreed, single GSMA specification for advanced communications. Carriers that deploy the Universal Profile guarantee interconnection with other carriers. 47 mobile network operators, 11 manufacturers, and 2 OS providers (Google and Microsoft) have announced their support. Google's Jibe Cloud platform is an implementation of the RCS Universal Profile, designed to help carriers launch RCS quickly and scale easily.
- Samsung is the major device OEM to support RCS globally. Samsung RCS capable devices have been commercially launched in Europe since 2012 and in the United States since 2015.
- Google supports RCS on Android devices with its Android SMS app Messages. In April 2018, it was reported that Google would be transferring the team that was working on its Google Allo messaging service to work on a wider RCS implementation, which will be marketed under the branding Chat.
- In June 2019, Google announced that it would begin to deploy RCS on an opt-in basis via the Messages app, with an RCS-compliant service hosted by Google rather than the user's carrier. The rollout of this functionality will begin in France and the United Kingdom, and it will be compatible with other RCS implementations compliant with the Universal Profile. In response to concerns over the lack of end-to-end encryption in RCS, Google stated that it would only retain message data in transit until it is delivered to the recipient.
The universal RCS profile
While RCS messaging was designed to move mobile networks beyond texting, different approaches made it difficult and costly for carriers to bring it to users.
By aligning on the GSMA's universal RCS profile - with the Messages RCS client app - carriers can now provide RCS messaging across the Android ecosystem.
