System and method for managing audio cut-in policy in mcptt communication

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 and a second floor request message from a tertiary floor participant, while a floor is granted to a secondary floor participant;
• applying, by the floor control server, an audio cut-in policy in response to determining that the first floor request message received from the primary floor participant is latest floor request message received;
• granting, by the floor control server, the floor to the primary floor participant while terminating a media transmission of the secondary floor participant by revoking the floor from the secondary floor participant;
• and
• transmitting, by the floor control server, a floor grant message to the primary floor participant and a floor taken message to the secondary floor participant and the tertiary floor participant, wherein the floor taken message includes information of the primary floor participant.

A floor control server for managing a mission critical push-to-talk (MCPTT) communication, the floor control server comprising:

• a communication unit configured to receive a floor request message from a primary floor participant while a floor is granted to the secondary floor participant,
• an audio cut-in policy unit configured to apply an audio cut-in policy, and
• a coordination unit configured to grant the floor to the primary floor participant while terminating a media transmission of the secondary floor participant by revoking the floor from the secondary floor participant, and
• transmit a first floor taken message to the secondary floor participant,
• wherein the first floor taken message includes information of the primary floor participant.

A floor control server for managing a mission critical push-to-talk (MCPTT) communication, the floor control server comprising:

• a primary floor control server;
• and
• a secondary floor control server;
• wherein the primary floor control server is configured to:
• receive a first floor request message from a primary floor participant while a floor is granted to a secondary floor participant,
• apply an audio cut-in policy, and
• grant the floor to the primary floor participant,
• wherein the secondary floor control server is configured to:
• receive a second floor request message from the secondary floor participant while the floor is granted to the primary floor participant, and
• forward the second floor request message received from the secondary floor participant to the primary control server, and
• wherein the primary control server is further configured to:
• receive the second floor request message forwarded from the secondary floor control server while the floor is granted to the primary floor participant,
• apply the audio cut-in policy,
• revoke the floor from the primary floor participant, and
• grant the floor to the secondary floor participant.
