Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an example of a system including a server and at least one terminal.

The system 1000 according to an embodiment may include a server 1100 and a plurality of user terminals 1200 to 1240 . The plurality of user terminals 1200 to 1240 is illustrated as five for convenience, but is not limited thereto.

For example, the system 1000 may be a system that provides a video call service. The video call service refers to a service in which a plurality of users can communicate with each other by transmitting their own images to the other party using their respective terminals and receiving the other's images. Users who use the video call service may exchange video and audio through their respective terminals, and may send and receive text through a chatting function.

A user who intends to use the video call service may directly designate a counterpart to whom the video call is made and use the video call service if the other party accepts the video call. Alternatively, the server 1100 that provides the video call service may designate a counterpart randomly or according to a predetermined method, and the user may use the video call service with the designated counterpart.

The server 1100 and the plurality of user terminals 1200 to 1240 may perform communication using a network. For example, a network includes a local area network (LAN), a wide area network (WAN), a value added network (VAN), a mobile radio communication network, a satellite communication network, and their It is a data communication network in a comprehensive sense that includes mutual combinations and enables each network constituent entity shown in FIG. 1 to communicate smoothly with each other, and may include a wired Internet, a wireless Internet, and a mobile wireless communication network. In addition, wireless communication is, for example, wireless LAN (Wi-Fi), Bluetooth, Bluetooth low energy, Zigbee, WFD (Wi-Fi Direct), UWB (ultra wideband), infrared communication (IrDA, infrared) Data Association), NFC (Near Field Communication), etc. may be there, but is not limited thereto.

The plurality of user terminals 1200 to 1240 include a smartphone, a tablet PC, a PC, a smart TV, a mobile phone, a personal digital assistant (PDA), a laptop, a media player, a micro server, a global positioning system (GPS) device, and an e-book terminal. , digital broadcast terminals, navigation devices, kiosks, MP3 players, digital cameras, home appliances, camera-equipped devices, and other mobile or non-mobile computing devices, but is not limited thereto.

The server 1100 may be an intermediary device that connects a plurality of user terminals 1200 to 1240 . The server 1100 may provide an intermediary service to transmit and receive data between the plurality of user terminals 1200 to 1240 . The server 1100 may transmit data to the plurality of user terminals 1200 to 1240 through a network or may receive data from the plurality of user terminals 1200 to 1240 .

The server 1100 may receive profile information from each of the plurality of user terminals 1200 to 1240 . The profile information may include at least one of a picture of each user, an image of each user, hobby information, nickname information, key information, date of birth information, gender information, residential area information, and school information.

For example, the user of the first terminal 1200 may execute an application provided by the server 1100 , and the first terminal 1200 is the user of the second terminals 1210 to 1240 from the server 1100 . Profile information of at least some of the users may be received.

That is, the user of the first terminal 1200 may be provided with profiles of some of the users of the second terminals 1210 to 1240 . For example, the user of the first terminal 1200 may generate a list including users with a favorable preference among users of the second terminals 1210 to 1240 based on the provided profile.

2 is a diagram illustrating an example in which a terminal is provided with profile information.

The first user of the first terminal 1200 may receive profile information of some of the users of the second terminals 1210 to 1240 from the server 1100 . For example, in FIG. 2 , the profile information 210 of the second user of the second terminal 1210 among a plurality of profile information received from the server 1100 is displayed on the display 200 of the first terminal 1200 . An example may be shown. The profile information 210 may include an image or an image including the face of the second user of the second terminal 1210 , but is not limited thereto.

For example, the like icon 220 and the non-like icon 230 may be displayed on the display 200 of the first terminal 1200 . The first user of the first terminal 1200 may select one of the favorable icon 220 and the unfavorable icon 230 based on the profile information 210 of the second user displayed on the display 200 . The first user of the first terminal 1200 may select the crush icon 220 if he wants to conduct a video call with the second user, and click the dislike icon 230 if he does not want to proceed with the video call with the second user. You can choose.

Meanwhile, the first terminal 1200 may transmit information that the first user has inputted a crush signal based on the profile information 210 of the second user to the server 1100 . Also, the second terminal 1210 may receive information from the first terminal 1200 or the server 1100 indicating that the first user of the first terminal 1200 has inputted a dislike signal.

As described above, when the user presses the crush icon 220 , the crush signal may be transmitted to the server 1100 , but is not limited thereto. For example, even when the user swipe or drags the crush icon 220 , the crush signal may be transmitted to the server 1100 . Similarly, when the user presses the unfavorable icon 230 , an unfavorable signal may be transmitted to the server 1100 , but is not limited thereto, and the unfavorable signal may be transmitted even when the user swipe or drag the unfavorable icon 230 . may be transmitted to the server 1100 .

3 is a diagram illustrating an example in which matching between terminals is completed.

As described above in FIG. 2 , the server 1100 may receive the crush signal transmitted from the first terminal 1200 based on the profile information of the second terminal 1210 .

Similarly, the profile information 310 of the first user of the first terminal 1200 may be displayed on the display 300 of the second terminal 1210 . In addition, the like icon 320 and the like icon 330 may be displayed on the display 300 of the second terminal 1210 . The second user of the second terminal 1210 may select the crush icon 320 if he wants to conduct a video call with the first user, and click the dislike icon 330 if he does not want to proceed with the video call with the first user. You can choose.

Also, the second terminal 1210 may transmit information that the second user has inputted a crush signal based on the profile information 310 of the first user to the server 1100 . As described above, when the second user presses the crush icon 320 , the crush signal may be transmitted to the server 1100 , but is not limited thereto. For example, even when the second user swipe or drags the crush icon 320 , the crush signal may be transmitted to the server 1100 .

At this time, the server 1100 receives the crush signal transmitted from the first terminal 1200 based on the profile information of the second user and the crush signal transmitted from the second terminal 1210 based on the profile information of the first user. When all are received, it may be determined that matching between the first user and the second user is completed. That is, the server 1100 determines whether the first user selected the unfavorable icon 230 based on the profile information 210 of the second user or the second user based on the profile information 310 of the first user. When information indicating that the unfavorable icon 330 is selected is received, it may be determined that matching between the first user and the second user is not completed.

4 is a diagram illustrating an example in which a call is transmitted when matching between terminals is completed.

When matching between the first user of the first terminal 1200 and the second user of the second terminal 1210 is completed, the server 1100 provides a call service between the first terminal 1200 and the second terminal 1210. can provide

For example, when matching between the first user of the first terminal 1200 and the second user of the second terminal 1210 is completed, the first terminal 1200 or the second terminal 1210 automatically initiates a call. can be sent out. That is, even if the first user or the second user does not input an input for performing a call to the first terminal 1200 or the second terminal 1210 , the call may be automatically transmitted.

The second terminal 1210 may receive the first crush signal transmitted from the first terminal 1200 to the server. Also, the second terminal 1210 may transmit a second liking signal for the first user of the first terminal 1200 to the server 1100 . In this case, the server 1100 may determine that matching between the first user of the first terminal 1200 and the second user of the second terminal 1210 is completed. Accordingly, the server 1100 may transmit a signal for establishing a call connection between the first terminal 1200 and the second terminal 1210 to the first terminal 1200 or the second terminal 1210 .

Referring to FIG. 4 , the second terminal 1210 may transmit the second crush signal to the first terminal 1200 after receiving the first crush signal. That is, the server 1100 receives the crush signal transmitted by the first terminal 1200 based on the profile information of the second user, and then the crush signal transmitted by the second terminal 1210 based on the profile information of the first user. signal can be received. In this case, the server 1100 may automatically transmit a call from the second terminal 1210 to the first terminal 1200 . For example, a call may be transmitted from the second terminal 1210 to the first terminal 1200 even if the second user of the second terminal 1210 does not perform a separate operation for making a call.

Meanwhile, the first terminal 1200 may determine whether to accept the call automatically sent from the second terminal 1210 . When the first terminal 1200 transmits a call accepting response to the server 1100 , a call between the first terminal 1200 and the second terminal 1210 may be performed. However, when the first terminal 1200 transmits a call rejection response to the server 1100 or the first terminal 1200 does not respond, the first terminal 1200 and the second terminal 1210 A call between the two may fail. However, the first terminal 1200 may store a list including users who have transmitted a crush signal from the first terminal 1200 to the server 1100, and the second user of the second terminal 1210 may store a list in the list. Since it is included, a call can be transmitted to the second terminal 1210 at any time. Similarly, since the first user of the first terminal 1200 is included in the list stored in the second terminal 1210 , the second terminal 1210 can make a call to the first terminal 1200 at any time.

Meanwhile, even when the first user of the first terminal 1200 is not connected to the application provided by the server 1100 , the first terminal 1200 may receive a call from the second terminal 1210 . .

In this way, when the matching between users is completed, a call is automatically transmitted, thereby eliminating the burden of users having to make a direct call to the other party.

When the server 1100 transmits a call from the second terminal 1210 to the first terminal 1200 , a preliminary call between the first user and the second user may be performed after the call waiting time has elapsed. That is, after the call waiting time elapses, the first user of the first terminal 1200 may determine whether to accept the outgoing call, and the first user of the first terminal 1200 accepts the outgoing call. In this case, a preliminary call between the first user of the first terminal and the second user of the second terminal 1210 may be connected.

The preliminary call may be performed before the main video call between the first user of the first terminal 1200 and the second user of the second terminal 1210 is performed. That is, the preliminary call may be performed before the first user and the second user decide whether to proceed with the video call. For example, the preliminary call may correspond to a video call or a voice call mediated for a preset time.

The first user of the first terminal 1200 and the second user of the second terminal 1210 may determine whether to proceed with the main call after the preliminary call is terminated.

For example, the preliminary call may correspond to a voice call and the main call may correspond to a video call. That is, since it is possible to determine whether to perform a video call through an audio call before performing the video call, which is the main call, users may feel less burdened in performing the video call. In addition, when the preliminary call is an audio call rather than a video call, the conversion rate to the main call, which is a video call, may be increased. Meanwhile, the present invention is not limited thereto, and the preliminary call may correspond to a video call, and the main call may also correspond to a video call.

5 shows an example of a screen displayed on a display of a terminal during a call waiting time.

4, after receiving the crush signal transmitted by the first terminal based on the profile information of the second user, the crush signal transmitted by the second terminal based on the profile information of the first user is received. In this case, the server 1100 may automatically transmit a call from the second terminal 1210 to the first terminal 1200 .

On the other hand, when a call is made from the second terminal 1210 to the first terminal 1200 , the second user of the second terminal 1210 and the first user of the first terminal 1210 after the call waiting time elapses Calls between them can be connected.

For example, after the call waiting time has elapsed, the first user of the first terminal 1200 may determine whether to accept the outgoing call. When the first user of the first terminal 1200 accepts the outgoing call, a preliminary call between the first user of the first terminal 1200 and the second user of the second terminal 1210 may be connected, and the first When the first user of the terminal 1200 rejects the outgoing call, the preliminary call between the first user of the first terminal 1200 and the second user of the second terminal 1210 may not be connected.

During the call waiting time, each camera of the first terminal 1200 and the second terminal 1210 may be activated. 5 illustrates an example of a screen displayed on the display of the second terminal 1210 during a call waiting time.

Referring to FIG. 5 , the camera of the second terminal 1210 may be activated during the call waiting time, and an image of the second user captured by the camera may be displayed on the display 500 of the second terminal 1210 . . Although not shown in FIG. 5 , the image of the first user captured by the camera of the first terminal 1200 may be similarly displayed on the display of the first terminal 1200 . Accordingly, the user can check his or her face before a call is connected.

Also, the call waiting time may be sequentially counted down, and a screen in which the call waiting time is sequentially counted down may be displayed on the display 500 of the second terminal 1210 . Meanwhile, in FIG. 5 , the call standby time is set to 10 seconds, but is not limited thereto. When the call waiting time is 10 seconds, a screen in which call waiting times are sequentially counted from '10' to '1' may be displayed on the display 500 of the second terminal 1210 . For example, a screen counting down from '10' to '1' may be displayed on the display 500 of the second terminal 1210 in units of 1 second, but in FIG. 5 , the countdown of the call waiting time starts Only a time point, a time point at which 7 seconds remain, a time point at which 3 seconds remain, and a time point at which the countdown is terminated are briefly illustrated.

Also, as the call waiting time is sequentially counted down, the visibility of the second user's image area 510 displayed on the display 500 of the second terminal 1210 may change. As the call waiting time is sequentially counted down, the width or transparency of the region 520 covering at least a portion of the display 500 of the second terminal 1210 may change. That is, as the area 520 that covers at least a part of the display 500 of the second terminal 1210 changes, the visibility of the second user's image area 510 displayed on the display 500 may change. .

For example, when the countdown of the call waiting time starts, the area 520 covering at least a part of the display 500 of the second terminal 1210 may cover all of the image area 510 of the second user. . As the call waiting time is sequentially counted down, the area 520 covering at least a portion of the display 500 of the second terminal 1210 may also gradually change. Accordingly, when the countdown of the call waiting time ends, the area 520 covering at least a part of the display 500 of the second terminal 1210 disappears, and the image area 510 of the second user is completely exposed. can

For example, as the call waiting time is sequentially counted down, the width of the area 520 covering at least a part of the display 500 of the second terminal 1210 may gradually decrease, and The transparency of the region 520 covering at least a portion of the display 500 may gradually increase.

Referring to FIG. 5A , the width of the area 520 covering at least a part of the display 500 of the second terminal 1210 at the time when the countdown of the call waiting time starts is the second terminal 1210 . may be the same as the width of the display 500 of the second terminal 1210, the transparency of the region 520 that covers at least a part of the display 500 of the second terminal 1210 is a level enough to cover the image region 510 of the second user It can have a set value.

Referring to FIG. 5B , when the call standby time is 7 seconds remaining, the width of the region 520 covering at least a portion of the display 500 of the second terminal 1210 is the display of the second terminal 1210 . It may be set to a value multiplied by 0.7 by the width of 500 , and the transparency of the area 520 covering at least a part of the display 500 of the second terminal 1210 may cover the image area 510 of the second user. It may be set to a value obtained by multiplying a preset value of the degree by 0.7.

Also, referring to FIG. 5C , when the call standby time is 3 seconds remaining, the width of the area 520 covering at least a portion of the display 500 of the second terminal 1210 is the second terminal 1210 . may be set to a value multiplied by 0.3 by the width of the display 500 of It may be set to a value obtained by multiplying a preset value sufficient to cover .

Also, referring to FIG. 5D , when the call standby time is over, the area 520 that covers at least a part of the display 500 of the second terminal 1210 disappears, and the image area of the second user disappears. (510) can be fully revealed.

As described above, the width of the area 520 covering at least a part of the display 500 of the second terminal 1210 may be determined as a value obtained by multiplying the width of the display 500 of the second terminal 1210 by a certain ratio. have. For example, the constant ratio may be set as a value obtained by dividing the remaining call waiting time by the call waiting time as the countdown proceeds, but is not limited thereto. Similarly, the transparency of the region 520 that covers at least a part of the display 500 of the second terminal 1210 may be determined as a value obtained by multiplying a preset transparency by a certain ratio. At this time, the preset transparency may be set to a value sufficient to completely cover the image area 510 of the second user, and a certain ratio is obtained by dividing the remaining call waiting time by the video call waiting time as the countdown proceeds. It may be set to a value, but is not limited thereto.

Meanwhile, the image of the first user may be displayed on the display of the first terminal 1200 during the call waiting time as well, and as the call waiting time is sequentially counted, an area covering at least a part of the screen of the first terminal 1200 The change of may be the same as described above.

6 shows another example of a screen displayed on a display of a terminal during a call waiting time.

6 illustrates an example of a screen displayed on the display of the first terminal 1200 when a call is transmitted from the second terminal 1210 to the first terminal 1200 .

First, when a call is sent from the second terminal 1210 to the first terminal 1200 , the display 600 of the first terminal 1200 informs that the call is originating from the second user of the second terminal 1210 . A message window 610 may be displayed.

After the message window 610 indicating that a call has been sent from the second user of the second terminal 1210 is displayed, the camera of the first terminal 1200 may be activated. The display 600 of the first terminal 1200 may display an image of the first user captured by the camera, and at the same time, a screen in which the call waiting time is sequentially counted down may be displayed. A screen in which the call waiting time is sequentially counted down may be the same as described above with reference to FIG. 4 .

Meanwhile, after the call waiting time is over, a message window 620 asking whether to accept the call with the second user of the second terminal 1210 may be displayed on the display of the first terminal 1210 .

When the first user of the first terminal 1200 selects the button to accept the outgoing call, a preliminary call between the first user of the first terminal 1200 and the second user of the second terminal 1210 is connected. can In addition, when the first user of the first terminal 1200 selects a button to reject the outgoing call, a preliminary call between the first user of the first terminal 1200 and the second user of the second terminal 1210 is selected. may not be connected.

For example, when the first user of the first terminal 1200 selects a button to accept the outgoing call, the server 1100 performs a preset call between the first terminal 1200 and the second terminal 1210 . You can mediate over time.

After a preset time during which the preliminary call is brokered has elapsed, the server 1100 receives a response to whether to perform the video call from the first user of the first terminal and the second user of the second terminal, You can decide whether to proceed with the call or not.

Meanwhile, during the preliminary call, the first screen displayed on the respective displays of the first terminal 1200 and the second terminal 1210 and the first terminal 1200 and the second terminal 1210 while the main video call is in progress ) The second screen displayed on each display may be different from each other. The first screen displayed on the respective displays of the first terminal 1200 and the second terminal 1210 during the preliminary call will be described with reference to FIG. 7 below.

7 illustrates an example of a screen displayed on a display of a terminal while a preliminary call is in progress.

During the preliminary call, the display of each of the first terminal 1200 and the second terminal 1210 may display an image area of a user of the opposite terminal performing a spare call and a blocking area covering at least a portion of the image area. . For example, the blocking area may change as a preset time during which the preliminary call is relayed elapses, and the visibility of the user's image area of the counterpart terminal may change based on the blocking area.

For example, each camera of the first terminal 1200 and the second terminal 1210 may be activated during a preset time during which the preliminary call is performed. The image of the second user captured by the camera of the second terminal 1210 may be displayed on the display of the first terminal 1200 , and the image of the second user captured by the camera of the second terminal 1210 may be displayed on the display of the second terminal 1210 . An image of the first user who becomes a user may be displayed. 6 shows an example of a screen displayed on the display 700 of the second terminal 1210 for a preset time.

Referring to FIG. 7 , preset times may be sequentially counted down, and a screen in which preset times are sequentially counted down may be displayed on the display 700 of the second terminal 1210 . Meanwhile, in FIG. 7 , the preset time is set to 30 seconds, but is not limited thereto. When the preset time is 30 seconds, a screen in which preset times from '30' to '1' are sequentially counted may be displayed on the display 700 of the second terminal 1210 . For example, a screen counting down from '30' to '1' may be displayed on the display 300 of the second terminal 1210 in units of 1 second, but in FIG. 7 , the countdown of the preset time starts Only a time point, a time point at which 15 seconds remain, a time point at which 3 seconds remain, and a time point at which the countdown is terminated are briefly illustrated.

Also, as the preset time is sequentially counted down, the visibility of the first user's image area 710 displayed on the display 700 of the second terminal 1210 may change. As the preset time is sequentially counted down, the width or transparency of the blocking area 720 covering at least a part of the display 700 of the second terminal 1210 may change. That is, as the blocking area 720 covering at least a part of the display 700 of the second terminal 1210 changes, the visibility of the first user's image area 710 displayed on the display 700 may change. have.

For example, the image area 710 of the first user may be completely revealed at the time when the countdown of the preset time starts. As the preset time is sequentially counted down, the blocking area 720 covering at least a portion of the display 700 of the second terminal 1210 may also gradually change. Accordingly, when the countdown of the preset time ends, the blocking area 720 covering at least a part of the display 700 of the second terminal 1210 may completely cover the image area 710 of the first user. have.

For example, as the preset time is sequentially counted down, the width of the blocking area 720 covering at least a portion of the display 700 of the second terminal 1210 may gradually increase. Alternatively, the transparency of the blocking region 720 covering at least a portion of the display of the second terminal 1210 may gradually decrease.

Referring to (a) of FIG. 7 , the image area 710 of the first user may be completely revealed at the point in time when the countdown of the preset time starts.

Referring to (b) of FIG. 7 , when the preset time is 15 seconds left, the width of the blocking area 720 covering at least a part of the display 700 of the second terminal 1210 is that of the second terminal 1210 . The width of the display 700 may be set to a value multiplied by 0.5, and the transparency of the blocking region 720 covering at least a part of the display 700 of the second terminal 1210 is the image region 710 of the first user. It may be set to a value multiplied by 0.5 from a preset value sufficient to cover .

In addition, referring to (c) of FIG. 7, when the video call standby time is 3 seconds remaining, the width of the blocking area 720 covering at least a part of the display 700 of the second terminal 1210 is the second terminal ( The width of the display 700 of the 1210 may be set to a value multiplied by 0.9, and the transparency of the blocking region 720 covering at least a part of the display 700 of the second terminal 1210 is the image region of the first user. It may be set to a value multiplied by 0.9 from a preset value sufficient to cover 710 .

In addition, referring to (d) of FIG. 7 , when the video call standby time is over, the width of the blocking area 720 covering at least a part of the display 700 of the second terminal 1210 is the second terminal ( The width of the display 700 of the 1210 may be set to be the same, and the transparency of the blocking region 720 covering at least a part of the display 700 of the second terminal 1210 is the image region 710 of the first user. It may be set to be the same as a preset value to cover the .

As described above, the width of the blocking region 720 covering at least a part of the display 700 of the second terminal 1210 is determined by multiplying the width of the display 700 of the second terminal 1210 by a certain ratio. can For example, the constant ratio may be set as a value obtained by dividing an elapsed time by a preset time as the countdown starts, but is not limited thereto. Similarly, the transparency of the blocking region 720 that covers at least a part of the display 700 of the second terminal 1210 may be determined as a value obtained by multiplying a preset transparency by a certain ratio. At this time, the preset transparency may be set to a value sufficient to completely cover the image area 710 of the first user, and the predetermined ratio is a value obtained by dividing the elapsed time by the preset time as the countdown starts. may be set, but is not limited thereto.

In addition, the image of the second user of the second terminal 1210 may be similarly displayed on the display of the first terminal 1200 for a preset time, and as the preset time is sequentially counted, the The change of the area covering at least a part of the display may be the same as described above.

As described above, as the preset time is sequentially counted down, the face of the other party is gradually hidden on the screen of the terminal, so that the user's burden can be relieved when deciding whether to proceed with the main video call after the preliminary call is ended. have.

Meanwhile, referring to (d) of FIG. 7 , after a preset time has elapsed, the display 700 of the second terminal 1210 requests a response as to whether to proceed with the video call with the first user. A message window 730 may be displayed. Also, after a preset time has elapsed, a message window requesting a response as to whether to proceed with the video call with the second user may be displayed on the display of the first terminal 1200 similarly. The responses of the first user and the second user may be transmitted to the server 1100 , and the server 1100 may or may not proceed with the video call based on the responses.

For example, the server 1100 may proceed with the video call when receiving a response from each of the first terminal 1200 and the second terminal 1210 that accepts whether to proceed with the video call. Also, when receiving a response rejecting whether to proceed with the video call from the first terminal 1200 or the second terminal 1210 , the server 1100 may not proceed with the video call.

8 is a diagram illustrating a process in which a video call is made in a system including a first terminal, a server, and a second terminal according to an embodiment.

Referring to FIG. 8 , in step 801 , the server 1100 may transmit profile information of the second user of the second terminal 1210 to the first terminal 1200 . Also, in step 802 , the server 1100 may transmit the profile information of the first user of the first terminal 1200 to the second terminal 1210 .

In step 803 , the first user of the first terminal 1200 may click the like icon based on the profile information of the second user. When the first user of the first terminal 1200 clicks the crush icon, the server may receive information from the first terminal 1200 that the first user has selected the crush icon based on the profile information of the second user. have.

Also, in step 804 , the second user of the second terminal 1210 may click the liking icon based on the profile information of the first user. When the second user of the second terminal 1210 clicks the crush icon, the server may receive information from the second terminal 1210 indicating that the second user has selected the crush icon based on the profile information of the first user. have. The server 1100 receives both the information that the first user has selected the crush icon based on the profile information of the second user and the information that the second user has selected the crush icon based on the profile information of the first user. In this case, it may be determined that matching between the first user and the second user is completed.

In step 805 , the server 1100 may automatically transmit a call from the second terminal 1210 to the first terminal 1200 . That is, the server 1100 may automatically transmit a call to the first terminal 1200 even if the second user does not perform an input for performing a call.

When a call is automatically sent from the second terminal to the first terminal 1200, a message window informing that the call is originating from the second user of the second terminal 1210 may be displayed on the display of the first terminal 1200. . When a call is automatically transmitted from the second terminal 1210 to the first terminal 1200 , a preliminary call between the second user and the first user may be connected after the call standby time has elapsed. The call waiting time may be sequentially counted down, and a screen in which the call waiting time is sequentially counted down may be displayed on the displays of the first terminal 1200 and the second terminal 1210 .

In step 806, the first terminal 1200 may accept the call after the call waiting time is over. For example, after the call waiting time is over, a message window asking whether to accept the call with the second user of the second terminal 1210 may be displayed on the display of the first terminal 1200 .

In step 807 , the server 1100 may set a time to broker a preliminary call between the first terminal 1200 and the second terminal 1210 . For example, the server 1100 may mediate the preliminary call only for a set time, and determine whether to proceed with the main video call after the set time has elapsed.

In step 808, the server 1100 may set a blocking area that changes as the set time is sequentially counted down. For example, the server 1100 may set the width and transparency of the blocking area that change as the set time is sequentially counted down. The blocking area may correspond to an area covering at least a portion of the display of each of the first terminal and the second terminal. The width of the blocking area may increase as the set time is sequentially counted down, and the transparency of the blocking area may decrease as the set time is sequentially counted down. For example, the width of the blocking area may be determined as a value obtained by multiplying the width of the display by a predetermined ratio. The constant ratio may be determined as a value obtained by dividing a time at which the countdown is performed in advance by the time at which the countdown is performed, but is not limited thereto. Similarly, the transparency of the blocking region may be determined as a value obtained by multiplying a preset transparency by a predetermined ratio. The constant ratio may be determined as a value obtained by dividing a time at which the countdown is performed in advance by the time at which the countdown is performed, but is not limited thereto.

In step 809, the server 1100 may output the blocking area to the displays of the first terminal and the second terminal. For example, the server 1100 may output a blocking area that changes based on the set width and transparency on the displays of the first terminal 1200 and the second terminal 1210 . As the blocking area that changes based on the determined width and transparency is output to the displays of the first terminal 1200 and the second terminal 1210, the image area of the second user displayed on the display of the first terminal 1200 is The visibility may change, and the visibility of the image region of the first user displayed on the display of the second terminal 1210 may change.

In operation 810 , the server 1100 may output a message window asking whether to proceed with the video call on the displays of the first terminal 1200 and the second terminal 1210 after the set time has elapsed.

In step 811 , the first terminal 1200 may transmit a response of accepting or rejecting whether to proceed with the video call to the server 1100 . Also, in step 812 , the second terminal 1210 may transmit, to the server 1100 , a response of accepting or rejecting whether to proceed with the video call.

In step 813, the server 1100 may determine whether to proceed with the video call based on the received response. For example, the server 1100 may extend the current video call when receiving a response accepting whether to proceed with the video call from each of the first terminal 1200 and the second terminal 1210 . Also, when receiving a response rejecting whether to proceed with the video call from the first terminal 1200 or the second terminal 1210 , the server 1100 may not proceed with the video call.

9 is a flowchart of a method for brokering a call according to an embodiment.

Referring to FIG. 9 , in step 910 , the server 1100 may check whether matching between the first user of the first terminal and the second user of the second terminal is completed.

For example, the server 1100 transmits a crush signal transmitted by the first terminal based on the profile information of the second user of the second terminal and the second terminal based on the profile information of the first user of the first terminal. When all of the crush signals are received, it may be determined that matching between the first user and the second user is complete. That is, the server 1100 sends an unfavorable signal transmitted by the first terminal based on the profile information of the second user of the second terminal or an unfavorable signal transmitted by the second terminal based on the profile information of the first user of the first terminal. is received, it may be determined that matching between the first user and the second user is not completed.

In step 920, the server may mediate a preliminary call between the first terminal and the second terminal for a preset time based on whether or not there is a match.

When matching between the first user of the first terminal and the second user of the second terminal is completed, the server 1100 may provide a call service between the first terminal and the second terminal. The server 1100 may transmit a request for establishing a communication connection between the first terminal and the second terminal to the first terminal or the second terminal.

That is, when matching between the first user of the first terminal and the second user of the second terminal is completed, the first terminal or the second terminal may automatically initiate a call. Even if the first user or the second user does not input to the first terminal or the second terminal for performing a call, the call may be automatically made. Also, when a call is automatically sent from the second terminal to the first terminal, a message window informing that the call is originating from the second user of the second terminal may be displayed on the display of the first terminal.

On the other hand, when a call is automatically transmitted from the second terminal to the first terminal, a preliminary call between the second user of the second terminal and the first user of the first terminal may be connected after the call waiting time has elapsed. For example, the preliminary call may correspond to a video call or a voice call mediated for a preset time. During the call waiting time, each camera of the first terminal and the second terminal may be activated. The call waiting time may be sequentially counted down, and a screen in which the call waiting time is sequentially counted down may be displayed on the displays of the first terminal and the second terminal. After the call waiting time is over, a message window asking whether to accept the call with the second user of the second terminal may be displayed on the display of the first terminal. When the first user of the first terminal selects the button for accepting the outgoing call, a preliminary call between the first user of the first terminal and the second user of the second terminal may be connected.

In this case, the server may mediate the preliminary call between the first terminal and the second terminal only for a preset time. Each camera of the first terminal and the second terminal may be activated for a preset time. The image of the second user captured by the camera of the second terminal may be displayed on the display of the first terminal, and the image of the first user photographed by the camera of the first terminal may be displayed on the display of the second terminal.

During the preset time, a screen for sequentially counting down the preset time may be displayed on each of the first terminal and the second terminal. As the preset time is sequentially counted down, the visibility of the image region of the second user displayed on the display of the first terminal changes, and the visibility of the image region of the first user displayed on the display of the second terminal changes. can

For example, as the preset time is sequentially counted down, the width of the first area that covers at least a part of the display of the first terminal increases, the transparency of the first area decreases, and at least a part of the display of the second terminal increases. The width of the second region to be covered may increase, and transparency of the second region may decrease.

In step 930, the server may receive, from each of the first terminal and the second terminal, a response as to whether to proceed with the main call after a preset time has elapsed.

After the preset time has elapsed, a message window for requesting a response as to whether to proceed with the main call with the first user may be displayed on the display of the second terminal. Also, after a preset time has elapsed, a message window requesting a response as to whether to proceed with the main call with the second user may be displayed on the display of the first terminal as well. The responses of the first user and the second user may be transmitted to the server 1100 . For example, this call may correspond to a video call or an audio call.

In operation 940, the server may determine whether to proceed with the call based on the response.

For example, the server may proceed with the main call when receiving a response accepting whether to proceed with the main call from each of the first user of the first terminal and the second user of the second terminal. Also, when receiving a response rejecting whether to proceed with the main call from the first user or the second user, the server 1100 may not proceed with the main call.

When the communication unit 1010 receives both the information that the first user has selected the crush icon based on the profile information of the second user and the information that the second user has selected the crush icon based on the profile information of the first user, In this case, the processor 920 may determine that matching between the first user and the second user is completed.

The processor 1020 may mediate a preliminary call between the first terminal and the second terminal for a predetermined time based on whether or not there is a match. The controller 1020 may set a time to broker the preliminary call, and may perform a countdown for the set time. The controller 1020 may determine the width of the blocking area that changes as the preset time is sequentially counted down, and may determine the transparency of the blocking area that changes as the preset time is sequentially counted down. The controller 1020 may output the blocking area on the screens of the first terminal and the second terminal, respectively, based on the determined width and transparency.

After a preset time has elapsed, the communication unit 1010 may receive a response to whether to proceed with the video call from each of the first terminal and the second terminal.

The processor 1020 may determine whether to proceed with the video call even after a preset time has elapsed based on the received response. The processor 1020 may proceed with the main video call when receiving a response for accepting whether to proceed with the video call from each of the first terminal and the second terminal. Also, when receiving a response rejecting whether to proceed with the video call from the first terminal or the second terminal, the processor 1020 may not proceed with the video call.
