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