Outline Brief introduction to Open Mobile Alliance (OMA) Why mobile broadcast in OMA? BCAST in OMA - What is that? Aspects on ensuring end-to-end interoperability Positioning of OMA enablers in the full system context Architecture of Mobile in OMA
Open Mobile Alliance Open Mobile Alliance (OMA) provides specifications that enable globally interoperable mobile services. The specifications are independent of transport, OS /execution environment, and hardware. By the end of 2004, there were 27 OMA Enabler Releases Produced and Published For example, MMS, DRM, Download, Browsing Hundreds of products with OMA specifications been commercially released and tested for interoperability in 8 Test Fests OMA has over 400 members The entire mobile industry value chain from content to user. Major categories: Content/ Providers, IT Companies, Operators, Vendors OMA is a catalyst for collaboration by Facilitating interoperability between technology implementations from various vendors through testing Reducing the overlap of work within other organizations and SDO s (3GPP, 3GPP2, ETSI, GSMA, ITU-T, Mobey Forum, MPF, W3C, WiFi)
Motivation for mobile broadcast work in OMA Mobile has significant business potential enables cost-efficient delivery of media content to large audiences Media industry has content which interests mobile users Mobile industry has infrastructure to manage distribution of media content to mobile users; and; to collect revenues from mobile consumers of media content Technology fragmentation is a BIG risk for realizing the globally significant business potential of Mobile! all the stakeholders of this business share the above concern: Mobile network operators Mobile service providers network operators ers and media companies Terminal vendors Network and IT infrastructure vendors
OMA Mobile s (BCAST) What does OMA mean by Mobile s? s which are made available through broadcast s which may jointly leverage the broadcast and the interaction s which can be received, used, and purchased with battery powered, wireless hand held terminals both indoor and outdoor Location of recipient/receiver may change over time Note: OMA scope is limited to bearer agnostic levels OMA BCAST SWG was created and chartered to Define the requirements for the enabler for Mobile s Specify the set of functions needed to enable the mobile broadcast, including but not limited to service guide, service/content protection Package the functions as a Enabler, which facilitates global interoperability and is bearer independent in order to be useful for a diverse and heterogeneous infrastructure.

Relevant work ongoing in several organizations In addition to OMA, Mobile standards work is done in the following, related groups: DVB (Work item on IP Datacast over DVB-H) 3GPP (Work item on MBMS) 3GPP2 (Work item on BCMCS) IETF WGs (RMT and MMUSIC)
