  • Patent number: 7720498
    Abstract: Apparatus and method are provided for displaying a push-to-talk (PTT) communication service subscriber having the right to speak in a portable terminal capable of using a PTT communication service. When the PTT communication service is executed, information of a PTT communication service subscriber having the speaking right is received. Image information is extracted from the received information of the PTT communication service subscriber having the speaking right. The extracted image information is displayed. While the PTT communication service is executed, an image of a buddy having the speaking right can be displayed. Accordingly, the PTT communication service can be realistically executed, the speaking right that is frequently shifted can be clearly identified, and user convenience can be improved.
