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.

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 Advanced Services / RCS Application Advanced Services Framework FW/NAT-T SIP/IMS Core SIMPLE XDM MSRP

10. 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

11. 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 Supports message-based operations Supports boundary-based message framing

12. ASF Components: XDM Toolkit XDM is used to access and manipulate various XML document stored across the network, all with established identity, authorization and appropriate security Complies with OMA definitions Main features: Enables the Application to send XCAP requests and receive responses to perform XDM operations on documents stored on the network Supports Contact List Management Supports Presence State Management Fully supports XML parsing Supports the use of both HTTP and HTTPS transports

13. Service Network Architecture

14. ASF Optional Component: FW/NAT Traversal TK Supports set of open standards for FW/NAT Traversal including: STUN (Simple Transfer of UDP through NATs) TURN (Traversal Using Relay NATs) ICE (Interactive Connectivity Establishment) Easily integrated with the SIP Toolkit Interoperable with wide variety of STUN and TURN servers
