摘要：The communication form of each terminal which participates in PTT

communication is registered in a call control server in advance. When performing PTTcommunication, a call control server (100a) detects the communication form of eachterminal. As a result, speech data is extracted from moving image data transmitted froma transmission terminal and is delivered to a speech PTT terminal which can receive onlyspeech data (S11, S12). On the other hand, moving image data transmitted from atransmission terminal is delivered to a moving image PTT terminal compatible withmoving image data without any change (S13). This makes it possible to implement PTTcommunication in accordance with the communication form of each terminal.
