    Description


    [0001] The present invention relates to a video call terminal, a mobile phone and a control method thereof, in which mutual communication is possible for an effective video call.

    [0002] US2006/0172766 describes a video calling method capable of providing video through a separate display over a VOIP network.

    [0003] A video call using a related art mobile phone is not supported between second generation (2G) type mobile phones or between a 2G type mobile phone and a third generation (3G) type mobile phone. Although video calls are supported between two 3G type mobile phones, it has not been widely used as compared with voice calls because video calls have disadvantages such as the mobile phone has to be kept elevated, its screen size is relatively small, and the call charge is more expensive than that of a voice call.

    [0004] Meanwhile, in the case of a voice call using a Voice over Internet Protocol (VoIP) type video call terminal such as a VoIP monitor, a user has to know network information for connecting with the other party terminal and do his/her own setup related to a network. Thus, use of the voice call is limited since it is complicated and inconvenient. Also, in the case of a monitor type video call terminal, voice and video are input and output through an open microphone, loudspeaker, camera, display, etc., and therefore the monitor type video call terminal is improper for a private call or a security-required video call.

    [0005] Therefore, according to an aspect of one or more exemplary embodiments, there is provided a video call terminal, a mobile phone and a control method thereof, which can make a video call more conveniently and inexpensively.

    [0006] Another aspect of one or more exemplary embodiments is to provide a video call terminal, a mobile phone and a control method thereof, which can allow unspecified individuals having no network information to make a video call.

    [0007] Still another aspect of one or more exemplary embodiments is to provide a video call terminal, a mobile phone and a control method thereof, which can make a video call while protecting privacy and maintaining security.

    [0008] The foregoing and/or other aspects may be achieved by providing a video call terminal, as defined by independent claim 1, including: a voice input unit through which a voice for a video call is input; a video input unit through which a video for the video call is input; a first communication unit which performs communication for the video call with the other party terminal through an Internet protocol (IP) network; a voice output unit which outputs a voice of the other party terminal for the video call; a video output unit which outputs a video of the other party terminal for the video call; a second communication unit which performs local communication with a mobile phone; and a controller which transmits network information of the video call terminal to the mobile phone as requested by the mobile phone, receives network information of the other party terminal from the mobile phone, and controls the video call with the other party terminal to be implemented on the basis of the received network information.

    [0009] The controller may control the voice output unit and/or the video output unit not to output at least one of a voice and video of the other party terminal.

    [0010] The video call terminal may further include a command receiver to receive a user's command, wherein the controller determines whether to output a voice and video of the other party terminal on the basis of the user's command.

    [0011] The controller may control at least one of a voice and video from the mobile phone to be received and transmitted to the other party terminal.

    [0012] The controller may control at least one of a voice and video of the other party terminal to be transmitted to the mobile phone.

    [0013] The video call terminal may further include a storage unit which stores a record of the video call, wherein the controller deletes the record of the video call with the other party terminal from the storage unit.

    [0014] Another aspect may be achieved by providing a control method, as defined by independent claim 9, of a video call terminal, the control method including: transmitting network information of the video call terminal to a mobile phone as requested by the mobile phone by implementing local communication with a mobile phone; receiving network information of the other party terminal from the mobile phone; and implementing communication for a video call with the other party through an Internet protocol (IP) network on the basis of the received network information of the other party terminal.

    [0015] The control method may further include outputting at least one of a voice and video of the other party terminal.

    [0016] The control method may further include inputting a user's command, wherein the outputting includes outputting the at least one of the voice and video of the other party terminal on the basis of the user's command.

    [0017] The control method may further include receiving at least one of a voice and video from the mobile phone; and transmitting the received at least one of the voice and the video to the other party terminal.

    [0018] The control method may further include transmitting the at least one of a voice and video of the other party terminal to the mobile phone.

    [0019] The control method may further include storing a record of the video call; and deleting the record of the video call with the other party terminal.

    [0020] The above and/or other aspects will become apparent and more readily appreciated from the following description of the exemplary embodiments, taken in conjunction with the accompanying drawings, in which:

    [0033] FIG. 4 illustrates an example of operations in the video call terminal 10a, the other party terminal 10b, the mobile phone 20a, and the other party phone 20b of FIGs. 1 to 3. In FIG. 4, one user employs the mobile phone 20a and the video call terminal 10a for the vide call, and another user employs the other party phone 20b and the other party terminal 10b (hereinafter, referred to as "the other party" or "the other party user").

    [0034] First, at operation 401, the mobile phone 20a tries a voice call with the other party phone 20b as requested by a user. Responding to this, the other party phone 20b is connected with the mobile phone 20a. In this state, a user and the other party can conduct a voice call through the mobile phone 20a and the other party phone 20b, respectively.

    [0035] Then, at operation 402a, the mobile phone 20a searches any device capable of a video call in the vicinity thereof. As a result of searching, if the video call terminal 10a is detected, the mobile phone 20a makes a request to the video call terminal 10a to transmit its network information. In this exemplary embodiment, the network information includes an internet protocol (IP) address, a gateway address, router information, etc. of the video call terminal 10a. At operation 403a, the video call terminal 10a transmits its own network information to the mobile phone 20a, in response to the network information request. Similarly, at the operations 402b and 403b, the other party phone 20b also acquires the network information of the other party terminal 10b.

    [0036] Next, at operation 404, the network information of the video call terminal 10a is transmitted from the mobile phone 20a to the other party phone 20b, and the network information of the other party terminal 10b is transmitted from the other party phone 20b to the mobile phone 20a. Then, at operation 405a, the mobile phone 20a transmits the network information of the other party terminal 10b, received from the other party phone 20b, to the video call terminal 10a. Likewise, at operation 405b, the other party phone 20b transmits the network information of the video call terminal 10a, received from the mobile phone 20a, to the other party terminal 10b.

    [0037] Then, at operation 406, the video call terminal 10a and the other party terminal 10b are connected for the video call on the basis of the received network information. When the video call connection is achieved, at operation 407a the video call terminal 10a receives an input voice signal and video signal for the video call and transmits the input voice signal and video signal to the other party terminal 10b, thereby allowing the other party terminal 10b to output the transmitted voice and video signals. Simultaneously, at operation 407b, the other party terminal 10a receives an input voice signal and video signal for the video call and transmits the input voice signal and video signal to the voice call terminal 10a , thereby allowing the video call terminal 10a to output the transmitted voice and video signals. If the video call is implemented between the video call terminal 10a and the other party terminal 10b, the mobile phone 20a and the other party terminal 10b may terminate a voice call at operations 408a and 408b.

    [0038] As described above, according to an exemplary embodiment, the video call is possible using the IP network such as the VoIP, so that it can be less expensive than using the mobile network. Also, network setup is automatically implemented for the video call between the video call terminal and the mobile phone, and therefore a user does not have to set up the network, thereby enhancing convenience and enabling unspecified individuals having no network information to make a video call.

    [0039] FIG. 5 illustrates another example of operations in the video call terminal 10a and the other party terminal 10b, and the mobile phone 20a and the other party phone 20b of FIGs. 1 to 3. In the exemplary embodiment of FIG. 5, repetitive illustration and descriptions about the configurations equal to or similar with that of FIG. 4 will be avoided as necessary. For example, the operations S401 to 405a and 405b are the same as those of FIG. 4, and thus they are not illustrated.

    [0040] Referring to FIG. 5, at operation 406 if the video call terminal 10a and the other party terminal 10b are connected for a video call, at operations 509a and 509b the video call terminal 10a and the other party terminal 10b respectively determine which devices will be used for outputting a voice signal and video signal of the video call. Specifically, the video call terminal 10a and the other party terminal 10b respectively display menus for allowing users to select output devices for the voice and video signals of the video call, and thus determine the output devices in accordance with a user's selection. The output devices can be variously selected. For example, both the video and voice signals of the video call may be output through only the video call terminal 10a. Alternatively, the video signal of the video call may be output through the video call terminal 10a, and the voice signal of the video call may be output through the mobile phone 20a. Further, both the video and voice signals of the video call may be output through only the mobile phone 20a. If a user selects the output device, at operations 510a and 510b the video call terminal 10a and the other party terminal 10b may transmit the selection results to the mobile phone 20a and the other party phone 20b, respectively. Alternatively, the selection of the output device may be carried out in the mobile phone 20a and/or the other party phone 20b. In this case, the mobile phone 20a and/or the other party phone 20b may transmit the selection results of the output devices to the video call terminal 10a and/or the other party terminal 10b, respectively.

    [0041] Then, at operation 511 the mobile phone 20a inputs the voice signal and/or video signal for the video call in accordance with the selection results of the output devices. At operation 512, the mobile phone 20a transmits the input voice signal and/or video signal for the video call to the video call terminal 10a. At operation 513, the video call terminal 10a sends the transmitted voice signal and/or video signal for the video call to the other party terminal 10b. At operation 514, the other party terminal 10b selectively sends the transmitted voice signal and/or video signal for the video call to the other party phone 20b in accordance with the other party's selection results of the output device. Also, at operation 515, the other party terminal 10b selectively outputs the transmitted voice signal and/or video signal for the video call in accordance with the selection results of the output device. Meanwhile, at operation 516, the other party phone 20b outputs the voice signal and/or video signal for the video call, transmitted from the other party terminal 10b.

    [0042] For convenience, the exemplary embodiment shown in FIG. 5 illustrates only the case that the voice signal and/or video signal for the video call are input to the mobile phone 20a and transmitted to and output through the other party phone 20b, but the exemplary embodiment is not limited thereto and is capable of operating in the reverse direction. Also, the exemplary embodiment shown in FIG. 5 describes that both the video call terminal 10a and the other party terminal 10b selects the output devices, respectively, but the exemplary embodiment is not limited thereto. Alternatively, only one of the video call terminal 10a and the other party terminal 10b may select the output device.

    [0043] As described above, according to an exemplary embodiment, the output of the voice signal and/or video signal for the video call is limited in an open video call terminal, but achieved in a private mobile phone. Accordingly, it is possible to protect privacy and maintain security.

    [0044] Although it is not shown in FIGs. 4 and 5, the video call terminal 10a and the other party terminal 10b can store and maintain a record of the video call. In this case, the video call terminal 10a and the other party terminal 10b may delete the record of the corresponding video call if requested by a user. In light of deleting the record of the video call, the video call terminal 10a and the other party terminal 10b may display a menu related to the record deletion of the video call and delete the record of the video call in accordance with a command input by a user. Accordingly, the privacy protection and the security maintenance can be further improved.

    [0045] Therefore, according to an exemplary embodiment, using only a video call terminal and a mobile phone, a video call is possible, and a private video call is also possible, all over the world beyond the limit of a local network. Also, unspecified individuals having no network information can make a video call. For example, anyone can readily make a video call, even while not in a place that uses a static IP address, like a home, but in a public place such as a café.

    [0046] Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles of the invention, the scope of which is defined in the appended claims.
