A method for managing a mission critical push-to-talk, MCPTT, communication, the method comprising: receiving, by a floor control server, a first floor request message from a primary floor participant while a floor is granted to a secondary floor participant (160(a)) and first media transmission is performed by the secondary floor participant (160(a)); in response to receiving the first floor request message, applying, by the floor control server, an audio cut-in policy; transmitting, by the floor control server, to the secondary floor participant (160(a)), a first floor revoke message for stopping the first media transmission of the secondary floor participant (160(a)) and transmitting, by the floor control server, a first floor grant message to the primary floor participant, based on the audio cut-in policy; transmitting, by the floor control server, to the secondary floor participant (160(a)), a first floor taken message including information of the primary floor participant granted the floor; receiving, by the floor control server, a second floor request message from the secondary floor participant (160(a)), while the floor is granted to the primary floor participant and second media transmission is performed by the primary floor participant; in response to receiving the second floor request message, applying, by the floor control server, the audio cut-in policy; transmitting, by the floor control server, to the primary floor participant, a second floor revoke message for stopping the second media transmission of the primary floor participant and transmitting, by the floor control server, a second floor grant message to the secondary floor participant (160(a)), based on the audio cut-in policy; and transmitting, by the floor control server, to the primary floor participant, a second floor taken message including information of the secondary floor participant (160(a)) granted the floor. receiving, by a floor control server, a first floor request message from a primary floor participant while a floor is granted to a secondary floor participant (160(a)) and first media transmission is performed by the secondary floor participant (160(a)); in response to receiving the first floor request message, applying, by the floor control server, an audio cut-in policy; transmitting, by the floor control server, to the secondary floor participant (160(a)), a first floor revoke message for stopping the first media transmission of the secondary floor participant (160(a)) and transmitting, by the floor control server, a first floor grant message to the primary floor participant, based on the audio cut-in policy; transmitting, by the floor control server, to the secondary floor participant (160(a)), a first floor taken message including information of the primary floor participant granted the floor; receiving, by the floor control server, a second floor request message from the secondary floor participant (160(a)), while the floor is granted to the primary floor participant and second media transmission is performed by the primary floor participant; in response to receiving the second floor request message, applying, by the floor control server, the audio cut-in policy; transmitting, by the floor control server, to the primary floor participant, a second floor revoke message for stopping the second media transmission of the primary floor participant and transmitting, by the floor control server, a second floor grant message to the secondary floor participant (160(a)), based on the audio cut-in policy; and transmitting, by the floor control server, to the primary floor participant, a second floor taken message including information of the secondary floor participant (160(a)) granted the floor.
