    Leveraging Unified Communications on IMS networks Leveraging Unified Communications on IMS networks Presentation Transcript

    • Leveraging Unified Communications on IMS networks
      Sagi Subocki
      Products Manager, Head of IMS segment
    • Unified Communication Services
      User Mobility
      Rich Presence
      Telephony (voice, fax, etc.)
      Voicemail/unified messaging
      Email/calendaring
      Conferencing (voice, video and web)
      Instant messaging
    • Unified Communication and IMS
      Enhancing the communication experience
      New advanced services
      Enabling enterprise communication services anytime, anywhere
      IMS enables connecting UC islands
      Service Providers piloting IMS-based UC-like services.
    • UC services over IMS
      Both IMS and UC heavily rely on SIP
      SIP: Open, Stable, Standard and Interoperable Foundation
      Presence is the new Dialtone!
    • UC service utilizing IMS
      Enhancing enterprise UC applications.
      Example:
      Federated Presence and Directory service
      City's Crisis Management Plan
    • Elements of Presence-based Services
      Based on Open Standards
      Includes the following:
      Presence – IETF/OMA SIMPLE
      Configuration for Contact lists, Preferences, Privacy, Security – OMA XDM/IETF XCAP
      Instant Messaging, File and Image Transfer – IETF MSRP
    • Applications of Presence-based Services
      SIP Networks
      IMS/NGN Networks
      Mobile phones/PDA
      PC and embedded voice/video/chat clients
      Set-top boxes and IPTV clients
      Video-share applications
      Interactive TV
      Gaming applications and appliances
      Collaboration solutions
      IP PBX
      IMS Rich Communication Suite (RCS)
    • IMS RCS (Rich Communication Suite)
      RCS – Initiative by GSMA
      RCS goal: facilitate services such as instant messages, buddy lists and video sharing among users and devices across different networks.
      Main elements of RCS:
      Enhanced Phonebook
      Enhanced Messaging
      Enriched Call
    • Advanced Services Framework Architecture
      Advanced Services / RCS Application
      Advanced Services Framework
      FW/NAT-T
      SIP/IMS Core
      SIMPLE
      XDM
      MSRP
    • ASF Components: SIMPLE Toolkit(SIP Toolkit + SIMPLE Add-On)
      Implements full set of SIMPLE-related RFCs, 3GPP and OMA specifications
      Can be used for development of any Presence and Instance Messaging application
      Main features:
      Serves as a Presence Engine for SIP/IMS applications
      Establishes presence subscriptions for remote parties and maintains remote party presence information
      Establishes WINFO subscriptions and maintains a “WINFO derived” buddy lists
      Maintains and publishes a local presence state
    • ASF Components: MSRP Toolkit
      Supports session and message-based Instant Messaging, as well as File Transfer and Image Sharing
      Can be used to build wide variety of applications from cell phones to the fixed clients and high-end servers.
      Implements IETF RFC4975
      Main features:
      Supports session-based operations
