  1. Open Mobile Alliance Presence Enabled Messaging Specifications Presence, Mobile Instant Messaging and Push to Talk Conference 21st-22nd January 2004 London, UK Mr. Frank Dawson, Chairman, Presence and Availability Working Group, Open Mobile Alliance

  2. Agenda • Open Mobile Alliance in brief • Presence in brief • OMA IMPS activities • Enabler Releases • IOP Testing and Benefits • Specification Evolution

  3. Open Mobile Alliance • The OMA is designed to be a center for mobile service specification work, stimulating and contributing to the creation of interoperable services “No matter what device or operating system you have, no matter what service you have, no matter what carrier you use, you can communicate, access and exchange information.”

  4. OMA’s mission • The mission of the Open Mobile Alliance is to facilitate global user adoption of mobile data services by specifying market driven mobile service enablers that ensure service interoperability across devices, geographies, service providers, operators, and networks while allowing businesses to compete through innovation and differentiation.

  5. Membership Update • As of December, 2003, OMA has approximately 350 member companies – representing the entire mobile value chain • Mobile Operators • Wireless Vendors • Information Technology Companies • Content Providers & Others • How to get involved • http://www.openmobilealliance.org

  6. Technical Plenary Working Groups Board of Directors Release Planning & Operations and Process Technical Plenary Management Committee Committee Interoperability Architecture Requirements Security Device Developers Game Services Management Interest Group Data Syncronization Mobile Mobile Web Location Commerce and Services Charging Push to Talk Browser and Presence and Messaging Availability Content Over Cellular

  7. Enabled IM, SMS, MMS, Chat, etc. Presence service as such Specific Active Phonebook, etc. PresenceAn enabler for other applications • Applications in the future are • Presence enabled (IM, multi-player games, etc.) • Presence specific (active phonebook, etc.) • IM being the first presence enabled application • Presence enables other applications to be richer, better and more valuable for the end user

  8. Presence Enabled Communication • Presence enhances end-user communication experience • People are interested in your availability • Presence initiates other communication • People do messaging instead of placing unanswered calls • Fixed Internet IM provides a paradigm for mobile IM

  9. Instant Messaging • Near real-timeexchange of messages containing multimedia content in a one-to-one or one-to-many connection • Instant Messaging is the first presence-enabled application in the mobile environment • Others to follow • Shared content • White board, conferencing, etc. • Group communication • Public/private chat rooms • Push to Talk over Cellular

  10. OMA IMPS v1.x Enabler Release • Completed in OMA IMPS working group • Based on contribution from Wireless Village initiative • V1.1 Specifications • Published November 2002 • Completed the consolidation of WV with OMA • Target for recent OMA IOP test events • V1.2 Specifications • Published February 2003 • Reflected implementation/IOP feedback • Focus of planned IOP test events

  11. Wireless Village Background • Formed in 2001 to specify mobile IMPS solution • Addressed common Presence and IM features • Services across both SMS and GPRS bearers • Both client-to-server and server-to-server specs • First specifications and demos in Feb 2002 • Numerous interoperability test events in 2002 • Consolidated into OMA in October 2002

  12. OMA IMPS v1.x Design Principles • Targets existing 2.5G and 3G networks • Service possible over SMS or GPRS connections • Based on IETF model for presence and IM (RFC2778) • Supports both mobile-to-mobile and mobile-to-Internet • Allow connection to existing IM portal communities • Lead use cases • “IM-ing” from mobile phones • Sharing one’s availability and status with contacts

  13. OMA IMPS v1.x Features • IM • Send and receive instant messages 1:1 or 1:many • Plain text and multimedia messages • Provisions for offline delivery • Presence • Update, share, subscribe and fetch presence information • List watchers of your presence • Contact list-based authorization model • Group Management • Administer public and private chat rooms • Search for, join/leave, invite to chat room discussions • Control access to presence information and chat rooms • Shared Content • Invite/cancel invitation to share content

  15. IOP Testing • Periodically scheduled OMA Test Fests • Targets individual OMA Service Enablers • Instrumental to identifying and fixing problems with OMA specifications • OMA IMPS 1.1 IOP testing conducted on: • Client-Server-Protocol (CSP) • Presence features • IM features • Numerous mobile and PC clients, as well as servers

  16. Benefits of Participation In OMA IOP Testing • Potentially expand the market with products and services that are based on OMA Service Enabler specifications and their interoperability tested implementations • Avoid costs and delays in product deployments by learning from early results of interoperability tests • Share views and expertise on how to the best resolve the technical issues related to OMA Service Enabler specifications and their implementation

  17. Specification Evolution • Separate the focus on presence and IM • IMPS WG split into separate Presence and Availability and Messaging working groups • Presence has applicability to other applications • Take current IM and Presence user-experience and separately extend to run over SIP technology • Work closely with 3GPP and 3GPP2 organizations • Explore Push to talk over cellular applications • Continue maintenance of v1.x specifications

  18. Collaboration / LiaisonWith Other Organizations • OMA activities necessitate collaboration and liaison with other industry bodies • Assure coordination of common requirements and technical specifications • Presence and IM activities within OMA involve such relationships with • 3GPP and 3GPP2 • GSMA and CDG • Parlay Group (PAM Forum) • IETF
