Samsung RCS AS

The next evolution of messaging

Samsung RCS AS is a hosted standards-based advanced messaging service that allows mobile network operators to rapidly deploy Rich Communication Services (RCS) with low risk and low capital expenditure. Created using the RCS standards defined by the GSMA, this service delivers to users many of the features found in popular third-party over-the-top messaging apps and provides an associated monetization ecosystem. This service is fully supported by Samsung flagship devices.

  • It supports specific national regulatory requirements.

1-to-1 chat is the core chat service that allows one user to exchange messages with another. Samsung RCS AS includes the basic features that are found in traditional SMS/MMS and enhances them with the following:

  • ‘Is typing’ notifications
  • Delivery status indicators
  • Higher message size limits (up to 8192 bytes)
  • Image sharing (taking and sharing pictures within a conversation)
  • Client fallback to SMS
  • Multiple 1-to-1 chat
  • Store and forward

The group chat feature in Samsung RCS AS allows users to exchange messages with many contacts at once in the same conversation. Members of a group chat will be aware of who is in the group and the messages sent by any group member in this conversation will be visible to all of its members.

Group chat incorporates many of the features found in 1-to-1 chat, as well as the following:

  • Easy creation
  • Subject titles
  • Auto accept
  • Store and forward
  • Long living group chats
  • Large groups (configurable, including profiles with 100 participants or more)

The file transfer feature in Samsung RCS AS allows users to send files to one or more contacts. This feature is accessible through 1-to-1 chat, group chat, camera, and gallery apps. It supports the following:

  • Transfer and receive files of any type.
  • Integrated content can be generated, displayed, and played directly in the client.
  • Delivery status indicators.
  • Choose picture and video size selections (high, medium, or low).
  • Large file sizes (configurable up to 100 MB).
  • Thumbnail previews.
  • Send contact information in VCF.
  • Send sketches.
  • Resume interrupted file transfers.
  • Store and forward.

The audio messaging feature in Samsung RCS AS allows users to send audio messages to one or more contacts. These are handled using the same rules as those found in file transfer, with the following features:

  • Record and send audio messages through 1-to-1 chat and in group chat.
  • Receive and listen to audio messages directly inside Samsung Messages app or another RCS-enabled client.

When Samsung Messages or another RCS-enabled client starts up, it will configure itself by connecting to a domain name defined by the RCS standard. This domain points to an RCS Auto-Configuration Server (ACS) that is part of Samsung RCS AS. This server authenticates the device. All of these steps are transparent to user.

Mobile network operators are able to:

  • Provide automatic and transparent configurations to user devices.
  • Enable, disable, or limit certain RCS functions.
  • Push configuration updates to existing users.

Device capability exchanges in Samsung RCS AS use the Discovery through Presence or OPTIONS mechanisms.
