The Open Mobile Alliance VISION No matter what device I have, No matter what service I want, No matter what carrier or network I m using, I can communicate, access and exchange information Created June 2002 by leading mobile operators, device and network suppliers, information technology companies, content and service providers -- now near 400 member companies International organisation developing open, market driven interoperable specifications for global adoption of data services Robust Interoperability Testing Program members test product implementations in a trusted zone 3

OMA deliverables and value OMA develops specifications, promoting application level interoperability Broadcast Services, Digital Rights Management, Mobile Location Services, Games Services, Device Management, Advertising, Messaging Reaching beyond mobile market Applicable to IP based networks both fixed and mobile Consumer Electronics devices Traditional PC and telephone environments OMA avoids duplication, divergence and fragmentation OMA has an extensive network of liaison relationships W3C, 3GPP/2, IETF, Java Community Process, Web Services Interoperability Organization, WiMAX Forum and others 4

OMA s work in messaging standards MMS Media Control Charging QoS........ Streaming Media Control Charging QoS........... Gaming Media Control Charging QoS........ OMA, like industry trends, has historically focused on the task at hand creating application silos Multimedia Messaging Instant Messaging (IMPS) Network Subsystem Streaming and Gaming Base Station Subsystem PoC Presence... IM For IMS-based enablers, OMA has improved matters Interoperability across different network types Working with 3GPP ensure OMA enablers and IMS are compatible Reusing other enablers such as Presence and XDM (for contact list and group management) e.g. PoC, SIMPLE IM 2.5G/3G IP Multimedia Subsystem Multi -service IP Network WLAN... Session Control Media Control QoS Charging....... PSTN 5

OMA s work in messaging standards OMA has new approach to messaging standardisation single set of protocols for communication services support for existing and many different user experiences accessible from any device, over any IP network multiple devices per user Interworks with existing messaging services and handsets common message repository reuse of other enablers e.g. Presence and XDM reuse of existing specifications e.g. PoC and SIMPLE IM, as needed Converged IP Messaging () 6

Improved Customer Experience Dave New phone Conversation with Anders Dave: Hi Anders Anders: Hi wassup?? New Platform Messaging Presence Presence Conversation model Multi-party conversations No limits to formats e.g. pictures, audio etc. Multiple Devices Dave: Hi will you be going to the Nokia meeting? Anders: Yes I was planning to attend between 2 and 4pm. Interworking with SMS/MMS SMS inbox Dave Dave Dave MMS inbox Dave: Great can we meet afterwards to discuss DVBH? BTW. Check out this new Nokia WiFi phone SMS/MMS Platforms Dave Dave Anders: Yep that would be great Saw the Nokia. It has integrated VoIP. I would also like to discuss WiFi strategy. Dave: OK no problem. See you later. MMS SMSC SMSB Anders Legacy SMS phone Anders: Cheers. 10

Technology convergence No need to maintain existing messaging silo applications in IP multimedia networks e.g. text only or voice only services Lack of interoperability between application platforms own O&M procedures own handset client and configuration data new training for engineers and customer care OMA moving to common, more generic platforms Enable converged messaging technology, and still support different user paradigms: push, session or pull Enable interworking between existing messaging services and a new converged messaging services Initial users must not be isolated! 11

Integration and Interoperability New services and network capabilities opportunities multiple access methods and services OMA track record of integrating fixed and mobile technologies to enable global interoperability Planning smooth migration of SMS/MMS user experience to new IMS-based messaging architecture This will require: specification of richer messaging experience for devices interworking between IMS-based Messaging and legacy MMS/SMS/IM/Voicemail services 14

New Vision: Converged IP Messaging Converged IP Messaging () enables creation of services allowing Communication without knowing the technology supporting a given messaging experience or session Parallel conversations across multiple devices and media types Personalised services through predetermined preferences E.g. which messages are sent to which device(s), Storage of any type of message and media in common network repository Seamless communication between legacy voice, video and messaging services (such as MMS, SMS), and services, Use of presence support to enhance communications experiences, Integration of all service communities within a single framework including a converged address book 15

Evolving Ecosystem User Non - enabled user User -enabled value-added application 1 5 4 2 Remote Enabler Service Provider 3 Subscriber 3 Enabler Service Provider Resources 6 Non - User In remote domain 1 User - using enabled communication services in his home domain 4 Value -added application communication services - using enabled over open interface 2 Remote User - using -enabled communication services between different -enabled domains 5 Non- User - using communication services with Users utilizing Enabler s interworking functions 3 Service provider offering -enabled services to its subscribers 6 Remote Non- User - using communication services with Users utilizing Enabler s interworking functions between domains 16

Use Cases Converged user paradigms in one conversation thread Check presence Presence List Checked Voice Call Started Start voice discussion Add unidirectional streamed video Add picture Video Clip Change over to text added Presence List Checked Chat Session Picture attached Multimedia group communication Multiple device environment Multiple addresses Seamless interworking between a user and a non- communication service user VAS application messaging Network-based storage (Common Repository) Converged address book Absence service t 17

Conversations - A New Paradigm A conversation is a dialogue between 2 or more parties Allows discrete message/media exchange and/or continuous media exchange Discrete message exchange can be part of a session, or outside a session Session is from the user perspective and depends only on whether the conversation is real time A conversation can be stored in the network (common repository) as a Thread 18
