Why Mobile Multicast / Broadcast?Why Mobile Multicast / Broadcast?

u May Help to Answer to the Question “What Happens When 3G Multimedia Applications Are Really Successful?”

u Guaranteed QoS� Not sensitive to time and space congestion � Broadcast traffic latency and QoS is unaffected by point-to-point network status and

traffic volumes� Most relevant for simulcast media streaming (“Mobile TV”) and notification apps

u Zero Incremental Cost� Efficiency benefit for high uptake services with common content� Use for catalog or teaser content to generate point-to-point transactions that are known

to have revenue attached to them• Avoid operator cost associated with unbilled point-to-point data traffic

� Relevant for content distribution applications even without QoS issues

u Localization� Natural localization at granularity of broadcast technology

• Network efficiency may allow finer localization based on client filtering


BCMCS OverviewBCMCS Overview

u Specification for Multicast Within EV-DO� Coexists with point-to-point packet data� Reuse and extension of existing IP packet encapsulation protocols� Single copy of multicast packet reaches all listeners

u Packets Sent Over Forward Link� Static: sent to a predetermined set of sectors� Dynamic: sent to sectors in which terminals have registered for a given flow

u New Functional Elements� Broadcast Serving Node: multicast packet distribution within core� Controller: multicast session information and scheduling, key distribution � Content Server: multicast reflector, encryptor

u Protocols Added for� Path setup and RAN session information� Session information to terminal� Security and media encryption


BCMCS Network ArchitectureBCMCS Network Architecture


BCMCS CapabilitiesBCMCS Capabilities

u Basic BCMCS (or ‘BCMCS Gold’)� Air interface defined in C.S0054� Physical layer reuses EV-DO Rev. 0 physical layer

• Enhancements such as soft combine

� Data rates up to ~400kbps

u Enhanced BCMCS (or ‘BCMCS Platinum’)� Air interface defined in C.S0054-A� Capability available in Rev. A chipsets� Physical layer uses OFDM, integrated with EV-DO TDM

• Improved energy and behavior at cell edges allows higher rates

� Data rates up to ~1.5Mbps

BCMCS As Mobile Broadcast BearerBCMCS As Mobile Broadcast Bearer

u Generic Broadcast Advantages� Zero incremental cost� Consistent QoS, simultaneous delivery

u Advantages Versus Dedicated Broadcast� Easy to roll out incrementally

• Existing radio network and receiver

� Dynamic resource usage• Network and/or terminal-driven path setup

� Fine-grained localization - sector level

u Disadvantages� Limited bandwidth

• Total IPDC bandwidth for single carrier smaller than typical dedicated network• Initial rollouts may cannibalize EV-DO data usage


Mobile Broadcast Application CategoriesMobile Broadcast Application Categories

u Mobile Streaming Media� High profile initial mobile broadcast application is “Mobile TV”� Improved video quality versus unicast simulcast media services� For high uptake, clear cost issues for unicast solution� Natural fit for existing broadcast infrastructure vendors

u Dynamic Multicast Media� Multicast PTT� Large-scale videoconferencing� Emergency notification

u IP Datacast� Content distribution� Real-time event streams� Large-scale real-time notifications

Datacast Application AttributesDatacast Application Attributes

Mix datacast modes and/or tie datacast to other broadcast content (trivia, voting, advertising)

Synergy

Trickle data in the background (“push portal”, may contain “teaser” or full content), or dynamically push data objects

Background Transfer

Network manages coarse- or fine-grained localization of content, may be further filtered by the client based on location

Localized Broadcast

DescriptionCharacteristic

Large # of clients receiving same data simultaneously; synch with “real world” events

Concurrent / Real-Time

“Bulk” data pushed, elements of interest are filtered up by client software

One way flow of structured data which is “visualized” on the mobile device (event stream, notifications, data object distribution)

Client Filtered

Push Data


Example Datacast ApplicationsExample Datacast Applications

Active Wallpaper Real-time Sports Datacasting Broadcast Storefront(“Push Portal”)

BCMCS Use Case: Optimization of Unicast ServicesBCMCS Use Case: Optimization of Unicast Services

u KDDI announcement of Gold BCMCS deployment� Preceded Rev. A deployment scheduled for EOY2006

u Multicast Employed for Optimized Versions of Services That Already Existed in That Market (and Others)

u “EZ News Flash”� Periodic update of news, weather, entertainment, sports information� Displayed on idle screen (“Active Wallpaper”)� Links to portal sites for additional information

u “EZ Channel”� Overnight download of media content subscribed to by user (“Push Portal”)� Currently point-to-point download


BCMCS Use Case: Localized DatacastBCMCS Use Case: Localized Datacast

u Asian Operator With Existing Partnership for Mobile TV� Dedicated mobile broadcast network operated by partner� Limited revenue share to mobile operator

u Trialing BCMCS for Localized Services� Limited media streams
