Hereinafter, a video call system and a method thereof according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

1 is a block diagram of a video call service system according to an embodiment of the present invention.

1, a video call service system according to an embodiment of the present invention, a plurality of originating terminals (111, 112, collectively referred to as 110 if no distinction is required below) forming an outgoing group, to form a destination group A plurality of called terminals 121, 122, collectively referred to as 120 if no distinction is required below, and a video call integration device 130 that interworks with the calling group and the called group through a wired or wireless communication network (mobile communication network, Internet, broadcasting network, etc.) do.

A plurality of originating terminals 110 conduct video calls with each other in an originating group, and an arbitrary originating terminal 110, for example, a first originating terminal 111, performs a video call with a called group during a video call. In order to connect the video call integration device 130 to request the integration of the video call.

The plurality of called terminals 120 conduct a video call with each other in a called group, and as the calling terminal 110 transmits a video call integration request, the call receiving terminal 120 receives an integrated request message from the video call integrator 130 during a call. In response, the approval or rejection message is transmitted to the video call integrator 130.

The video call integrating apparatus 130 transmits an integrated request message to all the called terminals 120 in the called group according to the video call integration request of the calling terminal 110, and all the called terminals 120 in the called group. Upon receiving approval from the caller, the caller terminal 110 in the caller group and the caller terminal 120 in the caller group are integrated to generate one unified group for conducting a video call.

The video call integration device 130 may be implemented in various forms according to the type of wired / wireless communication network, the calling terminal 110 or the called terminal 120. For example, a video call integrator in which a mobile switching center (MSC) or a GPRS support node (SGSN) in a mobile communication network integrates two video call groups, that is, a calling group and a called group. It may be used as a 130, a separate video call integration device 130 that performs a video call integration function in the broadcast network or the Internet may be built.

When creating a unified group, the video call unifying apparatus 130 releases a preset video call session in each of the calling group and the called group, and the user terminals belonging to the calling group and the called group, that is, the calling terminal in the calling group ( 110 and a video call session with each of the called terminals 120 in the called group, thereby connecting the multi-party video call of the unified group.

If only some user terminals in the called group approve the integrated request message, the video call integrating apparatus 130 integrates all the user terminals in the calling group and only the user terminals that have approved the integrated request message in the called group. Create one integration group. The user terminal that has approved the integrated request message in the called group participates in the unified group and the called group at the same time. In this case, the video call unifying apparatus 130 receives the video call traffic of the user terminal introduced from the called group into the unified group. Maintain the called group by forwarding to other user terminals in the group.

For example, while the first destination terminal 121 and the second destination terminal 122 perform a video call with each other by forming a destination group, video call integration is requested to the destination group, and the first destination terminal 121 is requested. Suppose that the video call integration is approved while the second called terminal 122 rejects the video call integration. In this case, the video call integrating apparatus 130 forms an integrated group by integrating all the calling terminals 110 and the first called terminal 121 in the calling group, but controls the video call traffic of the first called terminal 121. By forwarding to the second destination terminal 122, the video call connection between the first destination terminal 121 and the second destination terminal 122 and the presence of the destination group can be maintained as it is. At this time, the first destination terminal 121 participates in the unified group and the destination group at the same time.

As such, in a video call service using a wired / wireless communication network, when there are two video call groups (calling group and called group) in progress of a video call, a specific video call group (calling group) is assigned to the remaining video call group (called call group). When the video call integration request is made, the video call integration device 130 sends the integrated request message to all the destination terminals 120 in the destination group. If approval is received from all callers in the call group, the video call integrator 130 merges all the callers between the two video call groups (the call group and the call group). The integrated group allows video calls / conference calls to proceed.

Here, when merging two video call groups, there may be both a user who wants to belong to both video call groups and a user who does not want to participate at the same time, so only users who have approved video call integration can join the two video call groups. Belong to both video call groups, allowing them to participate in the conversation at the same time. According to this method, one caller may simultaneously participate in a plurality of video call groups and transmit their opinions, and the caller may be provided with information from the plurality of video call groups.

2A to 2E are diagrams illustrating screens of respective user terminals using the video call integration service of FIG. 1, illustrating screens of a calling terminal and a called terminal requesting video call integration.

2A shows a screen (left) of the called terminal C and the called terminal D in a video call, and a screen (right) of the calling terminal A and a calling terminal B in a video call.

While the calling terminal A is in the process of making a video call with the calling terminal B, the video call integrating apparatus 130 transmits the integration request message from the calling terminal A to the called terminal C as it requests the video call integration to the called terminal C. Then, it forwards it to the called terminal D. When the called terminals C and D approve the video call integration, the calling group and the called group are merged so that the users between the two video call groups participate in one integration group.

FIG. 2B shows a screen of the calling terminal A requesting video call integration to the called terminal C of the called group, and FIG. 2C shows a screen of the called terminal C receiving the received video. The video call integrator 130 transmits the integration request message to the called terminal C, and at the same time, forwards the integrated request message to the called terminal D in the call with the called terminal C to inquire whether the video call is integrated.

2D and 2E illustrate the screen mode of the calling terminal A after the called terminal C approves the video call integration to generate the unified group with the calling group.

When one user joins a plurality of video call groups, the video call integrator 130 may provide images of counterpart callers to the user terminal in various modes. Modes available in the user terminal are typically a bandwidth intensive method as shown in FIG. 2D, and a bandwidth equalization scheme as shown in FIG. 2E.

In the bandwidth concentrating method of FIG. 2D, when a user selects a video call group that is currently interested or delivers a word, the bandwidth is allocated to all the images of callers belonging to the selected video call group, and the remaining video call groups are allocated to the remaining video call groups. The image of the callers to be updated only a new image at a predetermined cycle. 2E divides and displays images of callers belonging to a plurality of video call groups in the screen of the user terminal, but divides and allocates limited bandwidth evenly to display images of each caller.

FIG. 3 is a detailed configuration diagram of the video call integration device shown in FIG. 1.

Referring to FIG. 3, the apparatus for integrating a video call includes an integration request query unit 131, a video call session integrator 132, and a traffic transmitter 133.

The integrated request query unit 131 receives a video call integration request from an originating group that is conducting a video call between a plurality of calling terminals 110, and integrates a video call with the calling group as the video call integration request is received from the calling group. An integrated request message for inquiring whether or not is generated and transmitted to the called group. The integration request message generated by the integration request query unit 131 is transmitted to all the plurality of destination terminals 120 undergoing a video call in the destination group.

When the video call session integrator 132 receives the approval from the called terminal 120 in the called group, the video call session integrating unit 132 receives the calling terminals 110 in the calling group and the called terminal 120 approved for the integrated video call in the called group. After releasing the preset video call session as a target, a new video call session is established with each of the user terminals whose video call session is released, thereby connecting the multi-party video call of the calling group and the called group. That is, the video call session integrating unit 132 is a preset video call session for all of the plurality of calling terminals 110 in the calling group and at least one called terminal 120 approving the integrated request message in the called group. After requesting to release the call, the video call session is established with each of the calling terminal 110 and the called terminal 120 in which the video call session has been released, in order to relay the video call by resetting the call path between the calling group and the called group. The video call is connected between the group and the called group.

When all of the plurality of called terminals 120 belonging to the called group have approved the integrated request message, the video call session integrating unit 132 may call all the plurality of calling terminals 110 in the calling group and all the plurality of called terminals in the called group. After requesting to release the preset video call session with respect to 120, the user establishes a video call session with each user terminal, whereby all the plurality of calling terminals 110 in the calling group and all the called terminals in the called group are connected to the unified group. Involve 120). If only a part of the plurality of called terminals 120 in the called group approves the integrated request message, all of the plurality of calling terminals 110 in the calling group and the called group are controlled under the control of the video call session integrating unit 132. One unified group is created in which only the called terminal 120 which has approved the unification request message among the plurality of called terminals 120 participates. In this case, the called group is maintained as it is, the receiving terminal 120 approved video call integration will participate in the called group and the integration group at the same time. In order to maintain the called group, the video call session integrator 132 integrates the video call traffic between the called terminal 120 and the calling group simultaneously participating in the called group and the integrated group through the traffic transmitter 133. Allows forwarding to another called terminal 120 in the rejected called group.

The traffic transmission unit 133, if some of the destination terminal 120 in the destination group rejects the video call integration, in order to maintain the destination group, the destination terminal introduced from the originating group and the destination group into the integration group Video call traffic between the 120 is forwarded to other destination terminals 120 in the destination group.

4 is a flowchart illustrating a video call service method according to an embodiment of the present invention, which illustrates a video call service providing a video call merge function.

If the caller attempts to connect the video call to a third user (called party) during the video call, but the other party is in the middle of the video call with another user (S110), the caller who attempted the connection has a specific button or feature code. By pressing, the video call integration device 130 requests the video call integration (merge) to receive an approval or rejection message from the called party (S120).

First, the first calling terminal 111 and the second calling terminal 112 form a calling group by connecting a video call to each other using a wired / wireless communication network (mobile communication network, broadcasting network, Internet, etc.) (S111). Similarly, a video call is connected between the first destination terminal 121 and the second destination terminal 122 through a wired / wireless communication network to form a destination group (S112).

The first calling terminal 111 of the calling group attempts to make a video call connection to a third user, that is, the first called terminal 121 of the called group, during the video call with the second calling terminal 112 (S113). ). The first called terminal 121 informs the first calling terminal 111 that the call is in progress, and the first calling terminal 111 that recognizes the call transmits a video call integration request to the video call integrating apparatus 130. The video call integrating apparatus 130 is the first call terminal 111 and the second call terminal 112 is a video call from the originating group in which the first call terminal 121 and the second call terminal 122 is a video call In step S121, the video call integration request for connecting the video call to the incoming call group is received.

Receiving the video call integration request, the video call integrator 130 determines whether the video call is integrated with the calling group for all the called terminals 120 belonging to the called group. The integrated request message is sent (S122, S123). That is, the integrated request message is transmitted to the first destination terminal 121 of the called party who is the video call request target (S121), and the integrated request message is transmitted to the second destination terminal 122 of the other party on the call with the called party. By forwarding and delivering (S123), the integrated request message is sent to all users in the called group. At this time, in order to allow the users in the called group to know the caller, information on the caller who requested the video call integration (mobile phone number, face image, etc.) together with the integrated request message, or in the calling group currently in call with the caller Information (mobile phone number, face image, etc.) about the other party's caller may be transmitted.

Users in the called group who receive the integration request message can approve the integration by pressing a specific button. If all the users in the destination group approve the integration, the video call integration device 130 generates a single integration group by integrating all the user terminals between the calling group and the destination group. At this time, the video call session between all calling terminals 110 in the calling group requesting video call integration and all called terminals 120 in the called group approving video calling integration pass through the video call integrating device 130. It is integrated in one path and all the user terminals in the integration group proceed with the video call through the video call session with the video call integration device 130. That is, when all the users in the called group approve the video call integration, after the preset video call session is released between the users in the calling group and the called group, the video call integrating device 130 and the calling group and the called group are released. As each video call session between users belonging to the group is newly established, a single unified group that connects the multi-party video call between the calling group and the called group is created.

If only some user terminals in the called group approve the video call integration, all the user terminals in the calling group and only some user terminals approved for integration in the called group are made. Specifically, when only some user terminals in the called group approve the unified request message, the unified group is created as a group in which only the user terminals that have approved the unified request message among the user groups of the calling group and the called group participate. The user terminal that approves the unification request message among the called groups participates in the unified group and the called group simultaneously.

In FIG. 4, the first destination terminal 121 approves the video call integration for convenience (S124), while the second destination terminal 122 rejects the video call integration (S125). In this case, each of the first calling terminal 111, the second calling terminal 112, and the first called terminal 121 may be preset in each of the called group and the calling group under the control of the video call integrator 130. After releasing the video call session (S131 to S134), each video call session is newly formed with the video call integrator 130 to form an integrated group, and the multi-party video call is connected through the video call integrator 130 ( S135, S136). As such, when only some user terminals in the called group approve the integrated request message, the video call consolidation apparatus 130 integrates only the user terminals in the calling group and the user terminals that approve the integrated request message in the called group. Create a unified group of (S130).

When only some users of the called group approve the video call, and the other users reject the video call, the user terminal that approves the integrated request message in the called group joins the unified group and the called group at the same time. At this time, the video call consolidation apparatus 130 receives video call traffic of the user terminal, for example, the first destination terminal 121, which flows from the destination group into the integration group, and other user terminals of the destination group, for example, the second destination terminal 122. Forwarding to ensure that the called group is maintained.

To this end, when only a specific user among the users who receive the integration request message approves the integration, and the remaining users reject the integration, the video call integration device 130 may approve the integration, for example, the first user. The receiving terminal 121 sends a message inquiring whether to simultaneously participate in the called group and the calling group, and inquires whether the simultaneous participation is performed (S126).

When the user who receives the simultaneous participation inquiry presses a specific button and approves to simultaneously participate in both video call groups (calling group and called group) (S127), the first called terminal 121 of the corresponding user is preset. The video call session is terminated (S131 and S133), and at the same time, the video call session with the video call integrator 130 is connected (S135).

The video call integrator 130 forwards the video call traffic of the user who has connected the video call session to the caller of the called group to which the user has previously called, and simultaneously communicates with the callers in the integrated group. Perform a video call. In the case of FIG. 4, since the first called terminal 121 simultaneously participates in the unified group and the called group, the video call integrating apparatus 130 removes the video call traffic of the first called terminal 121 connecting the session with itself. 2 Forward to the terminating terminal 122. As a result, if only some of the users in the called group approve the video call integration, the user of the called group who approved the video call integration will proceed with the video call with the callers in the called group previously, and request a new connection. Then, the video call with the callers of the integrated group that has approved this (S136).

Hereinafter, a video call system and a method thereof according to another embodiment of the present invention will be described in detail with reference to FIGS. 5 to 8.

5 is a configuration diagram of a video call service system according to another exemplary embodiment of the present invention, and FIG. 6 is a diagram illustrating screens of respective user terminals using the video call sharing service of FIG. 5.

Referring to FIG. 5, the video call service system according to another embodiment of the present invention includes a calling terminal 210, a plurality of called terminals 221, 222, 223, hereinafter referred to as 220 forming a sharing group, and wired and wireless networks. The video call sharing device 230 and the user profile server 240 interworking with the calling terminal 210 and the plurality of called terminals 220 through a communication network and controlling a sharing group.

In order to participate in the sharing group, the calling terminal 210 transmits a participation request for the sharing group to the video call sharing device 230, photographs authentication content for approval of participation, and provides the same to the video call sharing device 230. do. The plurality of called terminals 220 forms a sharing group capable of sharing content with each other through a video call session.

The video call sharing device 230 establishes a video call session with each of the plurality of destination terminals 220 belonging to the sharing group, sets up a sharing group, and requests a participation in the sharing group from the calling terminal 210 when the user profile server is present. The introductory content of the sharing group registered in advance is retrieved from the 240 and provided to the calling terminal 210. For example, when a caller wants to join a specific sharing group, when the call is sent by pressing a specific special character and the sharing group number of the desired sharing group, the video call sharing device 230 registers in advance during the outgoing connection. Introduction content (introduction image or image, string, etc.) of the sharing group is downloaded to the calling terminal 210, so that the caller can obtain information about the sharing group.

In addition, the authentication content is received from the originating terminal 210 requesting participation in the sharing group, and authentication is performed, and the approval of the participation of the sharing group is determined according to the authentication result.

The user profile server 240 registers contents for authentication for each user for a plurality of users, and provides contents for authentication of each user according to a request of the video call sharing device 230 in the process of performing authentication.

In the sharing group, the contents that can be shared include text, voice, image, and video provided through a video call path.

The calling terminal 210 accesses the video call sharing device 230, searches for a sharing group list first, and then selects a desired sharing group from the sharing group list and transmits a join request.

For example, if a caller joins the video call sharing device 230, selects a sharing group search menu, enters a keyword, or selects a category while the caller joins the sharing group A, the video call sharing device 230 is selected. Downloads introduction content such as a sharing group name and number, an introduction description, and the like related to the corresponding keyword to the calling terminal 210 so that the caller can obtain information about another sharing group. The calling terminal 210 may download the introduction content for the sharing group through the data logical channel or the control channel for the video call.

In such a system, a user who can make a video call using a wired / wireless network sends a call to a shared group number or a master terminal number of a shared group to request to join the shared group, and the shared group is provided during the outgoing connection. Introductory content (for example, teaser video streaming) can be viewed.

In FIG. 6, (a) shows a screen of the calling terminal 210 requesting to join the sharing group, and (b) shows that the called terminal 220 designated as the master terminal of the corresponding sharing group is the group of the calling terminal 210. The screen is an example of receiving a participation request.

During the outgoing connection, the calling terminal 210 photographs authentication contents such as a user's face and provides them to the video call sharing device 230, and the video call sharing device 230 receives the authentication content received from the calling terminal 210. To perform authentication by comparing with the user's authentication contents stored in the user profile server 240, and the user participates based on user information (eg, age, history, etc.) registered in the user profile server 240 After determining whether it is possible to access the corresponding sharing group, the video call is connected according to the determination result.

The video call sharing device 230 determines a user level of each user participating in the sharing group, and grants upload / download authority of each user terminal according to the determined user level. For example, when a user level is divided into a master, an uploadable user, and a general user, the master or uploadable users may upload source data such as an image or a video to the video call sharing device 230. Ordinary users are provided with the contents uploaded by the master or uploadable users by accessing the video call sharing device 230 by the master or uploadable users, or by the Uniform Resource Locator (URL) or IP (Internet) designated by the master or uploadable users. Protocol) You can download and enjoy the contents you want through the video call route in real time. In the case of general users who are not master or uploadable users, video upload is impossible, only the text or voice can be uploaded, and in the case of general users, uploadable users may be approved by the master.

FIG. 7 is a detailed configuration diagram of the video call sharing device shown in FIG. 5.

Referring to FIG. 7, the video call sharing apparatus includes a video call session processor 231, a participant user authentication unit 232, an integrated execution unit 233, an introductory content provider 234, and a shared group database 235. do.

The video call session processor 231 forms a video call session with each of the plurality of called terminals 220 to set up a sharing group capable of content sharing, and shares content among the plurality of called terminals 220 in the set sharing group. It plays a role of relaying. Contents that can be shared within a sharing group include text, voice, image, and video provided through a video call path.

When the participation user authentication unit 232 transmits a participation request for the sharing group from the calling terminal 210, it requests the authentication content to the calling terminal 210 and receives it, and is pre-registered in the user profile server 240. After retrieving the content for authentication of the user, authentication is performed by comparing the content for authentication transmitted from the calling terminal 210 with the content for authentication of the registered user. In addition, the participating user authentication unit 232 grants the upload / download authority of the calling terminal according to the user level in accordance with the result of authenticating the content for authentication.

The integration execution unit 233 determines whether to approve participation in the sharing group of the calling terminal 210 according to the user authentication result of the participating user authenticator 232, and informs the calling terminal 210 of the result. If the authentication of the originating terminal 210 is successfully performed by the participating user authentication unit 232, the integrated execution unit 233 controls the video call session processing unit 231 to renew the video call session of the originating terminal 210. By setting and joining the calling terminal 210 to the sharing group, the calling terminal 210 can share the content with the destination terminal 220 in the sharing group through the video call session connected to the video call sharing device 230 Support.

The introduction content providing unit 234 first provides a list of sharing groups for a plurality of sharing groups so that a user of the calling terminal 210 may select a sharing group to join. Subsequently, when a caller selects a specific sharing group from the sharing group list and the participation request for the sharing group is transmitted from the calling terminal 210, the introductory content provider 234 is registered in advance from the sharing group database 235. The introductory content of the sharing group is searched and provided to the calling terminal 210. The sharing group database 235 stores a list of sharing groups including a variety of information (shared group name, shared group number, shared terminal master terminal number, etc.) including introduction contents of each shared group for a plurality of shared groups.

The video call sharing device 230 forms a video call session with a plurality of user terminals to form a sharing group capable of content sharing, and relays content sharing within the sharing group to provide a content sharing service to users in the sharing group. (S210). A plurality of user terminals are designated as a video call sharing group during the multi-party video call through the video call sharing device 230, are assigned a sharing group number from the video call sharing device 230, and belong to the sharing group. The master terminal is designated among these. Alternatively, a specific user terminal may access the video call sharing device 230 to be assigned a sharing group number, and designate a master terminal in the sharing group.

The master terminal of the sharing group first starts a video call session with the video call sharing device 230 and starts sharing video call content such as streaming. Alternatively, while the video call is already in progress, the master terminal may start content sharing of the video call by pressing a specific button or a feature code. The contents that can be shared include various data such as text, voice, image, and video provided through a video call path.

In a sharing group, only a master terminal and a user terminal having a source provisioning authority designated by the master terminal can provide video content that can be viewed by users in the sharing group. Here, the method of providing content may be a direct video transmission method, an indirect video transmission method, a method of receiving from a specified URL, a method of receiving from a specified IP, or the like.

In the case of the direct video transmission method, the user terminal directly transmits the image captured by the user terminal or data in the user terminal to the video call sharing device 230 and then to another user terminal in the sharing group. In the case of the indirect video transmission method, a user capable of providing a master or a source belongs to two or more sharing groups at the same time, and transmits content provided from one side sharing group to a user terminal in another sharing group through the video call sharing device 230. do.

In the case of a method of receiving from a designated URL, the user terminal in the sharing group downloads data such as a video from an Internet site of a URL designated by the user who can provide the source. In the case of receiving from the designated IP, if the user who can provide the source designates the IP address of the computer running the utility that sends the streaming to the specific IP port, the user in the sharing group can access from the IP address in real time. Receive video data.

As such, content such as a video provided directly or indirectly by a master terminal of a sharing group or a user terminal having authority to provide a source, or transmitted from a specified IP / URL, is used by user terminals participating in the sharing group through a video call session. Can be delivered and viewed simultaneously.

The calling terminal 210 accesses the video call sharing device 230, retrieves a list of sharing groups, and transmits a join request to the video call sharing device 230 to join a specific sharing group desired by the caller. An outgoing connection is attempted to the master terminal of the group (S220).

The video call sharing device 230 provides the introductory content of the sharing group registered in advance to the calling terminal 210 during the outgoing connection (S230), and requests the content for authentication to the calling terminal 210 for authentication to provide it. Receive (S240). That is, when a user wants to participate in a specific video call sharing group, when a user sends a video call by inputting (specific special characters) + (shared group number) on the calling terminal 210, the calling terminal 210 makes a call. During the connection, the introductory content of the sharing group registered in advance from the video call sharing device 230 can be downloaded during the connection (S230), and at the same time, the user's authentication content (for example, a face image or video) is called from the calling terminal. The video call sharing apparatus 230 is transmitted from 210 to S230.

In this case, the video call sharing device 230 first provides the calling terminal 210 with a list of sharing groups for a plurality of sharing groups so that the caller can search for a sharing group that the caller wants to join, and then the caller sends a specific sharing group. If you select to receive a participation request for a specific sharing group from the originating terminal 210 in response to the sharing group list (S230)

Thereafter, the video call sharing device 230 authenticates the authentication content received from the calling terminal 210 during the outgoing connection with the authentication content of the registered caller in advance, and then authenticates the participation of the sharing group according to the authentication result. I approve it. In detail, the video call sharing device 230 confirms that the user is the user by comparing the user's authentication content received from the user terminal with the user's authentication content received from the user profile server 240 (S250). After transmitting the user's information stored in the server 240 to the master terminal of the sharing group and inquiring whether the user can participate in the sharing group requesting participation (S260), according to the response result of the master terminal (S270), the calling terminal Approve the participation of the sharing group of 210 (S280), or transmit a participation rejection message to the calling terminal (210) (S290).

In this case, the video call sharing device 230 may grant the upload / download right of the calling terminal 210 according to the user level according to the authentication result of the authentication content. For example, a user who participates in a sharing group for the first time may only download the video stream in real time, and may not transmit his or her own video, but may transmit his / her opinion only by text and voice to other users in the sharing group.

When a user can provide a source by specifying a master user, content such as a source video can be provided through direct / indirect upload, a method of specifying a URL with content, or an IP of content. have.

When the video call sharing device 230 approves participation of the calling terminal 210 in the sharing group, the calling terminal 210 forms a video call session with the video calling sharing device 230 and joins the sharing group, thereby allowing other members of the sharing group. Content sharing such as streaming with the user terminals becomes possible.
