Leveraging Unified Communications on IMS networks


Published on

Today, Unified Communication is the term of choice. While solutions for UC are abundant today, there will be a need to glue them all together. IMS offers the glue with its standardized architecture that fits native IP communications. IMS offers ways in which IMS enhances the UC experience, which will be explored in this presentation.

Leveraging Unified Communications on IMS networks

  1. 1. Leveraging Unified Communications on IMS networks<br />Sagi Subocki<br />Products Manager, Head of IMS segment<br />
  2. 2. Unified Communication Services<br />User Mobility <br />Rich Presence <br />Telephony (voice, fax, etc.) <br />Voicemail/unified messaging <br />Email/calendaring <br />Conferencing (voice, video and web) <br />Instant messaging <br />
  3. 3. Unified Communication and IMS<br />Enhancing the communication experience<br />New advanced services<br />Enabling enterprise communication services anytime, anywhere<br />IMS enables connecting UC islands<br />Service Providers piloting IMS-based UC-like services.<br />
  4. 4. UC services over IMS<br />Both IMS and UC heavily rely on SIP<br />SIP: Open, Stable, Standard and Interoperable Foundation<br />Presence is the new Dialtone!<br />
  5. 5. UC service utilizing IMS<br />Enhancing enterprise UC applications.<br />Example: <br />Federated Presence and Directory service<br />City&apos;s Crisis Management Plan<br />
  6. 6. Elements of Presence-based Services<br />Based on Open Standards<br />Includes the following:<br />Presence – IETF/OMA SIMPLE<br />Configuration for Contact lists, Preferences, Privacy, Security – OMA XDM/IETF XCAP<br />Instant Messaging, File and Image Transfer – IETF MSRP<br />
  7. 7. Applications of Presence-based Services<br />SIP Networks<br />IMS/NGN Networks<br />Mobile phones/PDA<br />PC and embedded voice/video/chat clients<br />Set-top boxes and IPTV clients<br />Video-share applications<br />Interactive TV<br />Gaming applications and appliances<br />Collaboration solutions<br />IP PBX<br />IMS Rich Communication Suite (RCS)<br />
  8. 8. IMS RCS (Rich Communication Suite)<br />RCS – Initiative by GSMA<br />RCS goal: facilitate services such as instant messages, buddy lists and video sharing among users and devices across different networks. <br />Main elements of RCS:<br />Enhanced Phonebook<br />Enhanced Messaging<br />Enriched Call<br />
