Abstract
A method for communicating using a Push To Talk (PTT) call traffic scheme in a mobile communication system. The method comprises the steps of selecting at least one subscriber with whom a calling user wants to communicate through the PTT call traffic scheme, determining if a Push To Data (PTD) is to be transmitted when sending a PTT call request, and selecting the PTD to be transmitted if the PTD is to be transmitted, in a calling mobile communication terminal, transmitting the PTD and the PTT call request message from the calling mobile communication terminal to at least one called mobile communication terminal of the selected subscriber via a PTT server, outputting contents of the PTD and indicating reception of the PTT call request to the selected subscriber by the called mobile communication terminal, when receiving the PTD and the PTT call request; and transmitting a PTT call request acceptance message to the PTT server to allow the calling and the called mobile communication terminals to communicate with each other through the PTT call traffic if the at least one called mobile communication terminal inputs the PTT call request acceptance key by the subscriber's operation.
