RCS Advanced Communications - Rich Communication Services

Summit Tech provides a full-featured, cross-platform Rich Communications Suite & Services (RCS Universal Profile) IMS stack & RCS SDK, RCS API and full featured client solutions ranging from RCS 5.1 clients, including support for VoLTE, to the latest RCS Universal Profile, all available across multiple form factors and platforms: Android, Android Wear, iOS, macOS, Windows Phone, Windows 7, 8, including RCS for Windows 10 and HTML5/WebRTC.

Individual SDK components and enablers within Summit's SDK are decoupled building blocks that can be integrated through RCS APIs with Summit's IMS / RCS stack or existing stacks and clients provided by carriers and OEMs. In addition, Summit's enhanced user-experience (UX) framework is available to OEMs allowing for the creation of a unique RCS flow that integrates seamlessly with existing components.

    Customized Enablers


    • Livecast: Users can broadcast live video from their handsets to multiple
      endpoints ranging from web browsers, smartphones and legacy phones

    RCS Web Gateway : Over-The-Top / WebRTC / Legacy Device Support

    To ensure RCS & RCSE clients have the widest possible reach, Summit offers an innovative IMS to web RCS gateway resulting in RCS web clients supporting both modern browsers supporting HTML 5 / WebRTC and legacy browsers and devices. Through RCS REST API (or Web Sockets), the CORG application server enables RCS web clients to share rich communication servivces with both web users and legacy devices.

    • For web endpoints (PC, Mac & Linux) signaling and traffic is encapsulated using the RTMP and HTTP-based RTMPT protocol supported by the Adobe Flash player

    • GSMA IR.84 support for legacy handsets is accomplished via RTSP/RTP re-encapsulation

    • Mobile to web call bandwidth is managed through CORG at both endpoints to ensure best possible quality

    Service Provisioning - Auto Configuration Server (ACS)


    The Summit Auto-Configuration Server (ACS) allows operators to easily deploy a scalable service provisioning solution for Rich Communication Services. Device management solutions (e.g. OMA DM) can be complex to integrate into telecom IP networks when factoring the additional requirement of deploying RCS combined with legacy services across multiple device OEMs, ranging from smartphones to tablets. ACS improves time-to-market by focusing on an operator's specific RCS configuration requirements as well as providing a customizable and adaptable interface to existing provisioning systems, including OMA DM.
