The objective of this technical report is to study how mission critical communication services utilize MBMS. This may include study of modifications to the MCPTT architectures and/or procedures as specified in TS 23.179. This technical report will identify any enhancements needed to support mission critical services delivered over MBMS, based on the stage 1 requirements, including TS 22.179, TS 22.280, TS 22.281 and TS 22.282.
