The RCS Landscape

The RCS initiative from the GSMA is intended to provide a specification for future IP-based messaging, voice and multi-media services, through which mobile operators will be able to remain relevant as a service provider in the face of the threat from OTT players. RCS is predicated around the MSISDN as the key end user identity, and defines a uniform set of capabilities around chat, group chat, file transfer and in-call content sharing that are interoperable across all mobile operators (like SMS) and across native RCS delivered on OEM devices.

The specification includes the RCS CPR profile, which defines an interoperable operator service covering legacy SMS, IP messaging, voice and video, across downloadable apps for smartphones, tablets, web and TV, and that is interoperable with native RCS from device OEMs. CPR introduced Enhanced Calling allowing the transformation of the user experience around voice calling.

Most recently, GSMA Universal Profile, supported by Google, to unify the regional variances of RCS and to accelerate the mass-market reach of RCS in all Android devices. Whilst not aiming to extend the feature set of RCS, Universal Profile will simplify, unify and lay the foundation for future A2P BOT services to be offered to RCS communities.

Opportunities provided by RCS for mobile operators are:

  • To remain relevant as a service provider (rather than just be an access provider) in the face of the cannibalisation of messaging revenues from the OTT players.
  • To offer a forward path for legacy messaging (like SMS and MMS), and to extend the reach of messaging and voice services to tablets, web and TV.
  • To take advantage of new propositions like Enhanced Calling and VoWiFi, preventing the future cannibalisation of voice revenues by OTT players.
  • To exploit their combined 4.7bn users by offering conversational services through the RCS service using A2P BOTs.

On the smartphone space, there is a wide range of vendors providing applications for RCS as the focus of the industry is still on the smartphones. Several device manufacturers are including a vanilla version of RCS into their high-end devices. Google itself joined the RCS ecosystem. Apple is still not in the game, and WIT is the solid provider of RCS apps for iOS. WIT is leveraging its state of the art RCS Stack to build an intuitive and easy to use interface for both Android and iOS devices as a complete communication application that can be launched by Mobile Operators.

What is the Universal Profile?

The Universal Profile, published in November 2016, is a globally agreed, single GSMA specification from which Operator advanced communications services are being built.

It contains a set of Advanced Calling and Messaging features and agreed enablers for innovation – such as application to person messaging (chatbots) and conversational commerce (the seamless integration of transactions and messaging), evolving SMS for 6.7 billion consumers.

As a result of the Universal Profile, most smartphones will ship with a built-in Advanced Messaging app, so consumers will easily be able to text, chat and share media without having to identify and download which apps their contacts are using.
