Question: In MCPTT (Mission Critical Push To Talk) services over 5G Systems, how can floor control messages be transmitted during group calls utilizing an MBS (Multicast/Broadcast Service) session?
Option 1: Always on a separate, dynamically created 5G MBS session distinct from the media transmission session.
Option 2: Optionally on a separate pre-created or dynamic 5G MBS session, or alternatively, on the same MBS session used for media packets.
Option 3: Exclusively on pre-arranged group call sessions and not on chat group calls that use MBS.
Option 4: Never on an MBS session; always via unicast transmission to each receiving user.
Explanation: According to the specifications for MCPTT services over 5G systems, floor control messages have flexibility in their transmission method. They can either be sent over the same pre-created 5G MBS session used for distributing media packets or, optionally, a separate 5G MBS session (which could be either pre-created or dynamically created) might be utilized specifically for these messages, accommodating different operational needs within both pre-arranged and chat group calls.
