• In CCSA, TC5 is responsible for the Mobile Multimedia Broadcast Service (MMBS) standardization activities in CCSA. – Research and conclude the strategy of Mobile Multimedia Broadcast

Service standardization• Application

– Industry Standards have been approved.• Technical Specifications• Test Specifications

– CCSA High Level Architecture for Mobile Multimedia Broadcast Service

– The Service Protection• Radio Bearer

– Candidate technical specification have been submitted to National Standard Committee

• Frequency– Frequency resources investigation report for Mobile Multimedia

Broadcast Service system have been published

Current Activities

Current Activities (2)

• Application part– Developing standards to specify an access-agnostic interoperable Mobile

Multimedia Broadcast Service – Recently completed work:

• Technical Report completed– Providing proposed solutions and recommendation for Mobile Multimedia

Broadcast Service standardization• Technical Specifications, providing

– The general requirement, – The service protection requirement– The service guide technical requirement– The service platform equipment specification– The terminal equipment specification– Interfaces Technical Specification– Service Interactive Technical Requirement

• Test Specifications– The service platform equipment test specification– The terminal equipment test specification

4

Strategic Direction

• The CCSA MMBS standards development has been defined in three phases:– Phase 1: Requirement and Technical research– Phase 2: Requirement and Technical specifications– Phase 3: Test specifications

• Convergence– The High Level Architecture to connect the different industry (The business cooperation

between telecommunication industry and broadcast)– Service protection:

• Smartcard profile

• Key exchange interface

– Service Guide– Service Interactive

• The CCSA MMBS standards align with the work of other SDOs: OMA, 3GPP, 3GPP2

• The CCSA MMBS standards mainly focus on the service and application domain.

5

Challenges

• Application– Gaps between telecommunication operation and broadcast operation

– Service Protection interface be accept by both role

– Service protection solution for Non-communication terminal

• Significant discussion on the connection between telecommunication operation and broadcast operation– Architecture

– Service protection

– Service guide

6

Next Steps/Actions

• Application– Test– Instruct the business cooperation between telecommunication

industry and broadcast – Service protection solution for Non-communication terminal– Content Protection
