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
