Patent number: 11412354Abstract: 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.Type: GrantFiled: December 2, 2020Date of Patent: August 9, 2022Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Min-suk Ko, Jun-hyuk Ko, Jae-sang Lim, Jin-su Jeong, Bo-ra Hyun
