2
4-7-2005Jerry Shih2 Outline History of MMS Project Where to Focus on Actions What is the Next Step
3
4-7-2005Jerry Shih3 Historical Background High Interests in the Industry Resulting in Parallel Efforts 3GPP Started the MMS Technical Specification Work in R99 3GPP Developed the MMS Network Reference Architecture which was Commonly Adopted Among Different Fora Initially, 7 Reference Points (MM1-MM7) were Identified in the Architecture and were Expanded to 10 In the Latest Release 3GPP Technical Specifications only Cover MM1, MM4 and MM7 WAP Forum (WAPF) Worked on Stage 3 of MM1 Reference Point With OMA Creation, WAPF work was Transferred to OMA 3GPP2 Started Their MMS Work Based on 3GPP R5 Specs 3GPP2 Developed Additional MM1 Interface based on SIP and MM3 Interface Based on EMAIL

4-7-2005Jerry Shih4 The Industry Landscape
5
4-7-2005Jerry Shih5 Problems with the Industry The Many Different Fora Working on MMS Created Confusion with the Following Problems: –Waste of Industry Resources –Too Many Meetings to Cover/Follow –Multiple Points for New Work Proposal –Multiple Decision Points for the Industry –Duplication of Similar Effort –Divergence of Functionality –Dangers of Backward and Forward Compatibility –Difficult in Interoperability Practices Hence in Global Roaming –Delay in Product Development
6
4-7-2005Jerry Shih6 Converged MMS Efforts OMA Hosted a MMS Workshop on November 7, 2003 Looking for a Better Way Moving Forward All Related MMS Fora (Such as OMA, 3GPP, 3GPP2, GSMA, CDG and Individual Companies) were Invited to Present Their Views Strong Consensus for a Unified MMS Industrial Activity in the Meeting Recommended to Combine Technology Independent Technical Specifications Development in One Place – OMA Progress Toward this Converged MMS Specification Development is Slow (many non-technical issues such as IPR and maintenance for existing Specs) The Starting Point is Post 3GPP R6 (OMA 1.3) Time Frame OMA MMSG Created the Landing Pad Task Force to Work On Recommendations on how to Move Forward

4-7-2005Jerry Shih7 Future MMS Specs Development Core Network Radio Access Network OMA (MMS, WAP,IM,Location, Games etc) 3GPP2 3GPP cdma2000 UMTS/EDGE Service Enabling Plane
8
4-7-2005Jerry Shih8 OMA Formed in June 2002 –WAP Forum –Location Interoperability Forum (LIF) –SyncML Initiative –MMS-IOP –Wireless Village –Mobile Gaming Interoperability Forum (MGIF) –Mobile Wireless Internet Forum (MWIF) Goals: –Deliver Technical Specs for Service Enablers to Reduce Industry Implementation Efforts –Ensure Interoperability (device, geographies, service providers, operators, networks, technologies) –Catalyst for the Consolidation of Standards –Provide Value and Benefits to all OMA Members

4-7-2005Jerry Shih9 OMA MMS 1.1 Summary Service Enabler Published in July2004 MMS Enabler 1.1 Contains the Protocol Specifications for MMS Client Communications. It uses WAP with the Functions of PUT, GET and PUSH Furthermore it Contains the MMS Conformance Document Version 2.0 (Define the MMS SMIL Presentation Language) The MMS Conformance Document 2.0 was Established by a Closed Manufacturer Group to Achieve Interoperability. Main Restrictions to 30 kByte on Message Size and a Selection of Media Formats (AMR, GIF, WBMP) The Attempt to Ensure Interoperability was not Successful
10
4-7-2005Jerry Shih10 OMA MMS 1.2 Objectives End-to-end Interoperability for mass market Person-to- Person MMS service Accelerated Commercial Availability (Major Push from GSMA) Persistent Network Based MM Storage Security on MM Content (Image Rich, Video)
11
4-7-2005Jerry Shih11 Main Elements for Interoperability Narrow the Scope for End-to-End Interoperability –No Mobile Device will Support all Available Media Types both for Technical and Economic Reasons –Core MM Content Domain Created –MM Content Classes Defined in Core MM Content Domain Guide the Mobile Device to Compliant with the Interoperability Scope –MM Creation Mode (Restricted, Warning, and Free) Content Adaptation –Major and Minor Adaptation Development
12
4-7-2005Jerry Shih12 New Functionality in MMS 1.2 –Terminal Capability Negotiation –MMBox –Digital Rights Management (DRM)
13
4-7-2005Jerry Shih13 OMA MMS 1.3 Objectives Person-to-Application, Content-to-Person Use Cases Better Content Protection Support User Device Evolution Message Template Application
14
4-7-2005Jerry Shih14 Classification of MMS Messaging Image Messaging -- Multimedia messaging using Image Basic, Image Rich and Megapixel MM content classes which are optimized for person-to-person use cases but also usable for content-to-person use cases Video Messaging – Multimedia messaging using Video Basic and Video Rich MM content classes which are optimized for person-to-person use cases but also usable for content-to-person and person-to-application use cases Content Messaging – Multimedia messaging using Content Basic or Content Rich MM content classes which are optimized for person-to-application and content-to- person services but also usable to person-to-person services with assisting techniques.
15
4-7-2005Jerry Shih15 Content Messaging Emphasis on Content Provider Use Cases –MMS Post Card Service –Consumer Headline News Clips –Consumer Webcam –Multiplayer Chess Game Better Content Protection Two new MM Content Classes Defined –Content Basic Content Class –Content Rich Content Class No Content Adaptation is Defined End-to-End Interoperability is not Defined
16
4-7-2005Jerry Shih16 Message Template Different way to Construct a Multimedia Message Service Provider Service Simplify the Composition of Feature-rich MM Examples: –MMS Originated Postcards –Greeting Cards –Multimedia Stationary –MMS Based Voting
17
4-7-2005Jerry Shih17 Summary OMA MMS 1.3 Service Enabler Introduces: –New Content Messaging (new Content MM Content Domain) –New Message Template Concept –Enhanced Voice Codec for Audio (AAC+) –Enhanced Video (SVG Tiny) –Enriched Image (1600 * 1200) (Megapixel and Content Rich content classes) –Better Content Protection (full DRM) –Sophisticated Presentation (PSS SMIL) –Optional Re-submission Mode
18
4-7-2005Jerry Shih18 MMS Next Step OMA MMS 1.3 Marks the end of the Current Technical Development –MMS 1.1 Service Enabler Package Published in 7-2004 –MMS 1.2 Candidate Enabler Package Approved in 06-2004 and Service Enabler Package Approved in 3-2005 –MMS 1.3 Technical Development Completed in 3-2005 Focus is on Service Deployment and Interoperability –Will see MMS 1.2 Deployed in 2005 –MMS 1.3 could be Deployed in 2006 Future Enhancements: –Spam and Fraud Control –User Service Management –Reliability and Maintainability
