Abstract: A terminal participates in a group call based on a Mission Critical Push to Talk (MCPTT) service. The terminal includes a baseband processor and an application processor. In some embodiments, the baseband processor receives an MCPTT service-related message from outside and determines whether to transmit the MCPTT service-related message to the application processor. The baseband processor may make the determination based on the MCPTT service-related message or based on an operation state of the application processor. As a result of the determining, some embodiments include performing, by at least one of the baseband processor and the application processor, MCPTT service-related operations.

Abstract: A method of operating a first terminal participating in a Mission Critical Push To Talk (MCPTT) group call in an off-network includes: receiving a first floor grant message configured to indicate a floor transfer from a second terminal to a third terminal; storing a Synchronization Source (SSRC) of the third terminal included in the first floor grant message as an SSRC of a next floor arbitrator; receiving a media packet or a floor control message; and, if a transmitter of the media packet or the floor control message is the next floor arbitrator, updating an SSRC of a current floor arbitrator as the SSRC of the next floor arbitrator.
