Terminal and operating method thereof

1. A terminal operating method comprising:

receiving, by a first terminal, profile information from each of a plurality of terminals;

receiving, by the first terminal, a first signal from each of a subset of the plurality of terminals;

receiving, at the first terminal, a second signal generated by a user of the first terminal, wherein the second signal is a favorable signal associated with a user of a second terminal of the subset of the plurality of terminals;

upon determining that the first signal from the second terminal is a favorable signal received from the user of the second terminal, sending, by the first terminal, a video call request to the second terminal; and

displaying, during a waiting time after the sending of the video call request, a screen sequentially counting down the waiting time on the first terminal until the waiting time ends; and

when the video call request is not accepted before the waiting time ends, displaying a message window on the first terminal to send a message to the second terminal.

2. The terminal operating method according to claim 1 , wherein the user of the first terminal has a first gender, and users of the plurality of terminals have a second gender.

3. The terminal operating method according to claim 1 , further comprising, in response to the second terminal declining the video call request during the waiting time, displaying a message window on the first terminal to send a message to the second terminal.

4. The terminal operating method according to claim 1 further comprising transmitting a third signal from the first terminal to a second subset of the plurality of terminals prior to receiving the first signals, wherein the third signal is transmitted based on profile information received from the plurality of terminals, and

profile information received from a certain terminal of the plurality of terminals comprises at least one of photographs, hobby information, nickname information, height information, date of birth information, gender information, residential area information, school information, and videos of a user of the certain terminal.

5. The terminal operating method according to claim 4 , wherein the first signal is a favorable signal regarding the profile information received from a certain terminal of the plurality of terminals, and the second signal is a favorable signal regarding profile information of the user of the first terminal.

6. A non-transitory computer readable recording medium where a program for performing the method of claim 1 , is recorded.

7. A terminal comprising:

a communication interface configured to communicate with a plurality of terminals;

an input/output interface configured to receive signals generated by a user of the terminal; and

a processor configured to:

receive, by the terminal, profile information from each of the plurality of terminals;

receive, by the terminal, a first signal from each of a subset of the plurality of terminals;

receive, at the terminal, a second signal generated by a user of the terminal, wherein the second signal is a favorable signal associated with a user of a second terminal of the subset of the plurality of terminals; and

if it determines that the first signal from the second terminal is a favorable signal received from the user of the second terminal, send, by the terminal, a video call request to the second terminal;

wherein, during a waiting time that begins after the sending of the video call request, the input/output interface displays a screen, on which the waiting time is sequentially counted down, until the waiting time ends; and

wherein, when the video call request is not accepted before the waiting time ends, the input/output interface displays a message window to send a message to the second terminal.

8. The terminal according to claim 7 , wherein the user of the terminal has a first gender, and users of the plurality of terminals have a second gender.

9. The terminal according to claim 7 , wherein, when a terminal receiving the video call request which is made by the processor does not accept the video call request before the waiting time, the input/output interface displays a message window to send a message to the second terminal.

10. The terminal according to claim 7 , wherein the processor is further configured to transmit a third signal from the terminal to a second subset of the plurality of terminals prior to receiving the second signal from each of the plurality of terminals, wherein the third signal is transmitted based on the profile information received by the plurality of terminals, and

the profile information received from a certain terminal of the plurality of terminals comprises at least one of photographs, hobby information, nickname information, height information, date of birth information, gender information, residential area information, school information, and videos of a user of the certain terminal.

11. The terminal according to claim 10 , wherein the second signal is a favorable signal regarding the profile information, and the first signal is a favorable signal regarding profile information of the user of the terminal.

12. The terminal operating method according to claim 1 , wherein receiving the first signal from each of the subset of the plurality of terminals comprises receiving the first signal through a server.

13. The terminal operating method according to claim 1 , further comprising transmitting the second signal to the second terminal through a server.

14. The terminal operating method according to claim 1 , wherein, if the user of the second terminal receives and accepts the video call request before the waiting time ends, a video call session is established between the first terminal and the second terminal.

15. The terminal according to claim 7 , wherein, if the user of the second terminal receives and accepts the video call request before the waiting time ends, the communication interface initiates a video call session with the second terminal.
