In a Push-To-All (PTA) service system and method enabling selective designation of data transmission targets, a transmitting PTA terminal (100-1) requests a selective data transmission to a PTA server (110) using a receiver-designated Talk Burst Control Protocol (TBCP) message containing information about some receiving PTA terminals (100-2,100-3) participating in the same session as the transmitting PTA terminal, and the PTA server transmits data received from the transmitting PTA terminal to designated receiving PTA terminals by referring to the information contained in the receiver-designated TBCP message. Thus, a selective data transmission can be performed within one PTA session. |
