Multimedia Broadcast/Multicast Service (MBMS) improvements; MBMS operation on demand
The present document covers:
- Use cases on the dynamically establishment of MBMS User Services to offload unicast delivery of certain contents, either real-time or non-real-time based, which reach a certain traffic volume due to the popularity of those contents.
- Use cases for terminating a previously established MBMS User Service due to subsequently decrease in its consumption.
- Recommended requirements on the BM-SC and UE to support on-demand MBMS.
- Gap analyses in the existing TR 26.346 specification for supporting the recommended requirements for MooD operation.
- High-level MBMS and unicast network architecture in the context of MooD.
- Message sequence diagrams illustrating examples of MooD operation.
- Description of solution frameworks that enable MooD operation, including configuration data, necessary interaction between BM-SC and UE to activate or trigger the MBMS client for reception of newly-established MBMS User Service, and the reporting of ongoing consumption of the MBMS service to enable measurement of ongoing demand for that service.
