Abstract

In a Push-To-All (PTA) service system and method enabling selective designation of data transmission targets, a transmitting PTA terminal requests a selective data transmission to a PTA server using a receiver-designated Talk Burst Control Protocol (TBCP) message containing information about some receiving PTA terminals 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.

Claims

1. A method, comprising:

joining a push-to-all (PTA) service session via an electronic device;

selecting a terminal from terminals participating in the session; and

transmitting a message to perform a selective transmission of content data between the electronic device and the terminal.

2. The method of claim 1, wherein the message comprises information of the terminal and the content data for the terminal.

3. The method of claim 1, wherein the message comprises a request for the selective transmission of the content data between the electronic device and the terminal and information of the terminal.

4. The method of claim 3, further comprising:

transmitting content data based at least in part on receiving a grant of the request.

5. The method of claim 1, wherein the message comprises a request for a termination of the selective transmission of the content data between the electronic device and the terminal.

6. The method of claim 1, wherein the transmitting comprises transmitting the message to a push-to-all service server hosting the push-to-all service session.

7. The method of claim 1, wherein the message is composed based at least in part on a talk burst control protocol (TBCP).

8. The method of claim 1, wherein the content data comprises at least one of push-to-talk (PTT) data, push-to-video (PTV) data, and message session relay protocol data.

9. A method, comprising:

establishing a push-to-all service session with a plurality of terminals, wherein the plurality of terminals comprises a first terminal and a second terminal;

receiving a request for a selective transmission of content data to the second terminal, from the first terminal;

receiving content data from the first terminal; and

transmitting the content data to the second terminal based at least in part on the request.

10. The method of claim 9, further comprising:

transmitting a message to grant the selective transmission of the content data in response to the request.

11. The method of claim 9, wherein the transmitting comprises terminating the selective transmission of the content data to the second terminal in response to another request for a termination of the selective transmission of the content data to the second terminal from the first terminal.

12. An apparatus, comprising:

a communication module; and

a controller operably coupled with the communication module, the controller configured to;

request a push-to-all service session,

select a terminal from terminals participating in the session, and

transmit a message to perform a selective transmission of content data between the apparatus and the terminal via the communication module.

13. The apparatus of claim 12, wherein the message comprises information of the terminal and the content data for the terminal.

14. The apparatus of claim 12, wherein the message comprises a request for the selective transmission of the content data between the apparatus and the terminal and information of the terminal.

15. The apparatus of claim 14, wherein the controller is configured to receive another message to grant the selective transmission of the content data in response to the request and transmit content data based at least in part on the other message.

16. The apparatus of claim 12, wherein the message comprises a request for a termination of the selective transmission of the content data between the apparatus and the terminal.

17. The apparatus of claim 12, wherein the controller is configured to transmit the message to perform a selective transmission of the content data between the apparatus and the terminal via the communication module to a push-to-all service server holding the push-to-all service session.

18. The apparatus of claim 12, wherein the message is composed based at least in part on a talk burst control protocol.

19. The method of claim 12, wherein the content data comprises at least one of push-to-talk data, push-to-video data, and message session relay protocol data.

20. A non-transitory, computer-readable storage medium comprising instructions, which when executed by one or more processors, cause the one or more processors to perform a method comprising:

establishing a push-to-all service session with a plurality of terminals, wherein the plurality of terminals comprises a first terminal and a second terminal;

receiving a request for a selective transmission of content data to the second terminal, from the first terminal;

receiving the content data from the first terminal; and

transmitting the content data to the second terminal based at least in part on the request.
