Study on Multimedia Broadcast and Multicast Service (MBMS) usage for mission critical communication services
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 3GPP TS 23.179 [6]. This technical report will identify any enhancements needed to support mission critical services delivered over MBMS, based on the stage 1 requirements, including 3GPP TS 22.179 [2], 3GPP TS 22.280 [3], 3GPP TS 22.281 [4] and 3GPP TS 22.282 [5].
