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.

Claims

1. A method for performing a Push To Talk (PTT) group communication using a PTT scheme in a mobile communication terminal, the method comprising 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 transfers the voice-recorded PTD data to a called mobile communication terminal of the selected called user for the one-to-one communication.

2. The method as claimed in claim 1, wherein, in the step of performing the voice-record operation, PTT group call traffic messages currently being received are temporally buffered.

3. The method as claimed in claim 1, wherein, in the step of performing the voice-record operation, group call traffic messages currently being received are discarded.

4. A method for performing a Push To Talk (PTT) group communication using a PTT scheme in a mobile communication terminal, the method comprising 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;

displaying menu items for the user to select one of two operations, when the user performs a Push To Data (PTD)-sending operation in a mobile communication terminal, wherein the two operations comprise a first operation for sending one of previously stored files and a second operation for recording a voice;

performing the second operation for recording the voice, if the menu item for the second operation is selected; and

transmitting the voice-recorded PTD data to a PTT server which transfers the PTD data to a mobile communication terminal of the selected called user for one-to-one communication.

5. The method as claimed in claim 4, wherein the method further comprises:

selecting a desired file from among the previously stored files, if the menu item for the first operation is selected; and

transmitting the selected file to the PTT server which then transfers the selected file to the mobile communication terminal of the selected called user for one-to-one communication.

6. The method as claimed in claim 4, wherein, in the step of performing the second operation for recording the voice, PTT group call traffic messages currently being received are temporally buffered.

7. The method as claimed in claim 5, wherein, in the step of performing the second operation for recording the voice, PTT group call traffic messages currently being received are temporally buffered.

8. The method as claimed in claim 4, wherein, in the step of performing the second operation for recording the voice, group call traffic messages currently being received is discarded.

9. The method as claimed in claim 5, wherein, in the step of performing the second operation for recording the voice, group call traffic messages currently being received is discarded.

10. Program code embodied on a computer-readable medium comprising:

a first set of instructions for selecting one called user, with whom a calling user wants to communicate through one-to-one communication, from a Push To Talk (PTT) communication group of members that are taking part in the PTT group communication;

a second set of instructions for performing a voice-record operation, if a predetermined Push To Data (PTD)-sending operation is executed for the one-to-one communication; and

a third set of instructions for transmitting the voice-recorded PTD data to a PTT server which transfers the voice-recorded PTD data to a called mobile communication terminal of the selected called user for the one-to-one communication.

11. Program code as claimed in claim 10, wherein said second set of instructions for performing the voice-record operation, PTT group call traffic messages currently being received are temporally buffered.
