Particularly for voice communication, the National Public Safety Telecommunications Council (NPSTC) has previously defined that mission critical voice, such as MCPTT, must include direct mode, off-network capability or it cannot be considered for mission critical use ('Mission Critical Voice Communications Requirements for Public Safety', August 2011). In addition to voice operation, off-network capabilities for data are also required, for example to be used in rail communication when exchanging data for train safety purposes. As part of the ongoing study of FS_MCOver5GS, SA WG6 is currently analysing the key issues for enabling Mission Critical services over 5GS. It has identified that direct mode, D2D, communication mechanisms, including UE-to-Network Relay, are lacking in 5GS, creating a significant gap to e","secretary_remarks":"Response drafted in SP-190254.
