  • Patent number: 9088875
    Abstract: Provided is a communication terminal that prevents a listener from missing a conversation during a group call and enables the listener to identify a speaker. Mobile telephones of users B and C receive, from a mobile telephone of a user A who is a speaker, DTMF information having a value of “1” and identifying the user A, and audio data of the user A; output an identification tone indicated by the DTMF information, and audio of the user A; and store the DTMF information and a flag indicating “other”. When a speaker is switched to the user B, the mobile telephone of the user B generates audio data of the user B, selects DTMF information having a value of “2” as information identifying the user B; and transmits the selected DTMF information and the audio data of the user B to the mobile telephones of the users A and C.
