  • 1. Leveraging Unified Communications on IMS networks
    Sagi Subocki
    Products Manager, Head of IMS segment
  • 2. Unified Communication Services
    User Mobility
    Rich Presence
    Telephony (voice, fax, etc.)
    Voicemail/unified messaging
    Email/calendaring
    Conferencing (voice, video and web)
    Instant messaging
  • 3. 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.
  • 4. UC services over IMS
    Both IMS and UC heavily rely on SIP
    SIP: Open, Stable, Standard and Interoperable Foundation
    Presence is the new Dialtone!
  • 5. UC service utilizing IMS
    Enhancing enterprise UC applications.
    Example:
    Federated Presence and Directory service
    City's Crisis Management Plan
  • 6. 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
  • 7. 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)
  • 8. 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
  • 9. Advanced Services Framework Architecture
