  • Patent number: 11412354
    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.
