7. Question 5/16: Mobility for Multimedia Systems & Services recommendations • Scope: • To develop recommendations on Mobility for Multimedia System and Services with end-to-end IP transport

8. Question 5 Work Items • Enhance H.323 systems with Terminal, user, service mobility in All IP networks • Develop Global Mobility Management system for Interoperability between H.323 and mobile networks • Enhance Presence and Instant Messaging capability in the H.323 mobility systems • Develop interoperability between Presence and Instant Messaging Servers and H.323 mobility systems

9. Q.5/16 WORK PLAN (2001-2004) • Progress work on recommendations: • H.MMS.0 (General Mobility Management for Multimedia Systems) • H.MMS.1 (Mobility for H.323 Multimedia Systems) • H.MMS.2 (Global Mobility Management Interoperability) • H.MMS.3 (Mobility Presence for Multimedia Systems and Services) • H.MMS.4 (Interoperability between Presence and Instant Messaging and Mobility Presence MM service)

10. Work plan cont..

11. H.323 Mobility Network Architecture – in progress

12. H.246 Annex E Network Architecture

13. Progress: H.246 annex E • H.246 Annex E.1, E.2 recommendations (H.323 & Mobile Networks Inter-working Gateway) • Allows H.323 terminals to be identified as Mobile phones • Published H.246 Annex E.1 (software based User Identification Module (e.g., SoftSIM) • Published H.246 Annex E.2 (H.323 and North American Mobile Networks IWG) • Future work on H.246 Annex E.3 (IWG for GSM), E.4 (IWG for PDC, Japan) • Works with zero changes to PLMN

14. H.246 Annex E1, E2 Recommendations new usages 1. Utilize the PC (or other IP device) as a Mobile Station (handset) - User Identity Module (UIM) is uploaded into Laptop, PDA • For GSM, SIM card adapter to PCMCIA or USB 2. PC connects to managed IP network via ISP or corporate LAN 3. The PC application uses UIM to register with the VLR/MSC (via the GK) 4. PLMN HLR is updated with the location of the mobile subscriber in H.323 Network. 5. Subscriber’s mobile services will be enabled for End-user in the H.323 network and Terminal (e.g., delivery of voice calls, SMS services etc.)

MM 1 External Server#1 (e.g. E-Mail) External Server#N (e.g. Fax-GW) „Foreign“ MMS Relay/Server 3GPP MMS Standards - Architecture Elements Status: Release 4, 2001: Completed Stage 1 (Requirements), Stage 2 (Architecture) Release 5, 2002: Stage 3 (protocols and procedures) MMS Relay/Server (MM 2)

16. GSM Association: M-Services Task Group • What is the Mobile (M-Services) Services Task Group? • GSM Association formed MSIG (Mobile Services Interest Group) now known as M-Services Task Group • To address mobile handset services fragmentation • To publish mobile features guideline that aim to help ensure that operators could depend on a certain set of consistent features and services in mobile handsets • Released M-Services phase1 guidelines document with timeline (year 2000, 2001) for the availability of products with the specified mobile data services • Working on releasing M-Services Phase 2 guidelines document with timeline (year 2002-2003) for the availability of terminals, network functions products with specified mobile data services. • All GSM/GRPS/WCDMA carriers and some vendors like Intel, Openwave, Microsoft, are behind this effort.

17. M-Services Phase 2 work • What are the core elements that M-Services phase2 guidelines document will cover? • The M-Services Phase II Guidelines cover: • Custom User Interfaces • Browsers for Mobile Terminals • A common framework for Downloading consumer/operator-oriented content • Multimedia Messaging Services • Usage models for a number of common applications in phones like Presence and real-time collaboration features like video phone, Multimedia Instant Messaging etc.

18. M-Services Task GroupDeliverables • Complete Phase-II M-Services guidelines document by Q1, 2002 • Complete the M-Services Phase II Test Handbook for conformance and inter-operability testing by Q1, 2002. • Complete minimum performance benchmark document for phase-II M-Services (e.g., Mobile Multimedia terminal performance benchmark) • For insuring uniform and acceptable end-user experience.

19. Multimedia Messaging Services will be new revenue generating services in Wireless Internet markets Standards and Inter-operability testing will the key for success of MMS and TTM advantage Future Mobile Collaboration services like Presence with location information will be the key enablers of MMS Summary Call to Action Need IMTC’s help in leading Inter-operability testing bake-off events of Multimedia Messaging Services including Multimedia Instant Messaging and Presence Service
