Abstract
A method for performing a Push To Talk (PTT) group communication using a PTT scheme in a mobile communication terminal is disclosed. The method includes the steps of selecting one called user with whom a calling user wants to communicate through one-to-one communication from a PTT communication group of members that are taking part in the PTT group communication, performing a voice-record operation, if a predetermined Push To Data (PTD)-sending operation is executed for the one-to-one communication, and transmitting the voice-recorded PTD data to a PTT server which then transfers the voice-recorded PTD data to a called mobile communication terminal of the selected called user for the one-to-one communication. The PTT group communication allows two terminals to communicate with each other by a one-two-one scheme even while the PTT group communication is progressing.
