However, the real-time shared chat system mentioned below includes at least one of the components shown in FIG. 1, but is not limited thereto.

The first terminal 110 and the second terminal 120 may perform a chat (or messenger) function with each other through the network 130 while at the same time sharing a real-time function between the terminals (first terminal or second terminal) Terminal. That is, a terminal that provides a real-time sharing function without interruption during communication such as a chat between the first terminal 110 and the second terminal 120. Although only the first terminal 110 and the second terminal 120 are shown in FIG. 1, the real-time sharing chat system according to the present invention may include more terminals. That is, a plurality of terminals in excess of two can receive a real-time shared chat service according to the present invention. In the present specification, a service sharing two or more terminal-to-terminal and real-time functions is referred to as "real-time shared chat ".

The chat referred to in the present invention refers to a service capable of exchanging various types of messages in real time with communication users worldwide based on RCS (Rich Communication Suite), and can perform one-to-one text chatting or group chatting among a plurality of users can do. In addition, the function of the terminal, which is the real-time sharing target of the terminal in the present specification, can be collectively referred to as all the functions that can be performed in the terminal, and includes functions basically installed in the terminal, application). Examples of such functions may include screen sharing between terminals, audio sharing, control, sketching, file transmission, camera sharing, location sharing, and the like.

If you look at the functions of each terminal, the sketch function means a service that can communicate with the other party by handwriting or picture. That is, a display (e.g., a letter, a picture, or the like) received from the user by the touch input can be outputted from the counterpart terminal equally. The audio sharing function refers to a service shared by the terminal, such as audio or voice, which is output from the terminal or input to the terminal. The screen sharing function means a service for sharing the terminal screen of the user to the other party. The location sharing function refers to a service that shares my place, another place, or desired place with a map application or the like. The camera sharing function is a service that shares the screen viewed with the camera to the other party. The control function means a service for remotely controlling a counterpart terminal through a screen output from the counterpart terminal, and the control authority can be performed only under the acceptance of the controlled terminal. The file transfer function refers to a service for transferring photographs, images, address books, documents, etc. by utilizing the RCS file transfer function.

An example of real-time shared chat according to the present invention using the functions of the terminal is as follows. In an example of screen sharing or audio sharing, a screen (i.e., image) or audio And can perform character chatting while outputting the same (mirroring) to the counterpart terminal through streaming. In addition, as an example of the above-described control function, it is possible to control the setting of the counterpart terminal to be changed or to control the content transmission so that the counterpart terminal can receive the content of the counterpart terminal while mirroring the counterpart terminal's screen. In addition, in the example of the sketch function described above, a character or a picture input from one terminal may be displayed on the other terminal and stored in the other terminal while outputting the same screen to each other. As described above, by outputting the same input from the screen and the user at both terminals, it is possible to edit documents in real time by sharing various documents and the like. In addition, as an example of the camera function described above, a character chat can be performed while a screen viewed through a camera from one terminal is outputted as a background screen on both terminals equally. In addition, it is possible to share the current location of both terminals and output the same on the screen of both terminals, for example, as an example of the location sharing function. As an example of the above-described file transfer function, it is also possible to transfer a file (photo, image, music, document file, etc.) from one terminal to another terminal while the aforementioned functions are mutually shared. Also, it is possible to simultaneously perform text chatting while simultaneously executing the same application in both terminals.

In order to perform a real-time shared chat between terminals, any one of the chatting terminals requests a real-time shared chat to the counterpart terminal (i.e., real-time sharing request) . In addition, in order to perform a real-time shared chat between terminals, a terminal in real-time sharing may request a real-time shared chat (i.e., a chat request) with a counterpart terminal and may be connected to each other by a counterpart terminal responding thereto. At this time, in addition to the response message indicating acceptance or rejection, the counterpart terminal that has requested the real-time shared chat can determine whether the real-time shared chat operation is possible and transmit a response message (possible or not) to the requesting terminal. In addition, although not shown in FIG. 1, a service server supporting real-time shared chat is additionally included in the real-time shared chat system to determine whether real-time shared chat can be performed for each terminal. That is, when a terminal requesting a real-time shared chat requests a real-time shared chat by specifying a counterpart terminal, the service server determines whether or not the specified counterpart terminal can perform a real-time shared chat operation and transmits a response message To the requesting terminal.

The first terminal 110 and the second terminal 120 described in the present specification may be used in a mobile phone, a smart phone, a tablet PC, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), a cellular phone, a PCS (Global System for Mobile) phone, a WCDMA (Wideband CDMA) phone, a MBS (Mobile Broadband System) phone, and the like. Although FIG. 1 shows only a mobile terminal, a PC, a notebook, . Of course, this is merely an example, and it should be construed as a concept including a device that is currently developed, commercialized, or capable of all communication to be developed in the future, in addition to the above-described examples.

The network 130 refers to a data communication network for data transmission and information exchange between the first terminal 110 and the second terminal 120, and the type thereof is not particularly limited. For example, i-bimnet, which provides high-capacity data transmission and reception services through Internet Protocol (IP), and data service without disconnection, is an i-bimetal architecture that integrates different networks based on IP, It can be network. The network 130 may be a mobile communication network including a wired network, a Wibro (Wireless Broadband) network, a Wimax (World Interoperability for Microwave Access) network, a mobile communication network including WCDMA, a High Speed Downlink Packet Access (HSDPA) , LTE advanced mobile communication network, satellite communication network, and WLAN (Wi-Fi) network.

Hereinafter, for the sake of convenience of description, a situation in which a real-time screen sharing function is performed during a chat between terminals will be described as an example, and this will be referred to as "real-time screen sharing chat ". However, the present invention is not limited to this, and it is possible to share various functions in addition to the real-time screen sharing among the chatting terminals as described above. Hereinafter, it is assumed that a terminal that provides a screen of its own to a counterpart terminal in real time is a terminal 1 (or a user A), a terminal that receives a screen of a counterpart terminal in real time is called a terminal 2 (or a user B) .

FIG. 2 is a view illustrating a screen of each terminal before a real-time screen sharing chat according to an embodiment of the present invention.

2 (a) illustrates a screen of the terminal 1, and FIG. 2 (b) illustrates a screen of the terminal 2. FIG.

2, a real-time screen sharing chat related icon 213 for activating (or requesting) the real-time screen sharing chatting function is provided at the upper part of the chat screens 210 and 250 of the terminals (terminal 1 and terminal 2) 253) is displayed. Of course, this is only an example, and the real-time screen sharing chat related icons 213 and 253 can be displayed in addition to the other screens in the chat screens 210 and 250 as well as the chat screens 210 and 250 .

When the terminal 1 receives a touch input to the icon 213 from the user to request a real time screen sharing chat to the other terminal, the terminal 1 transmits a message for requesting the real time screen sharing chat to the terminal 2 (or the service server). At this time, when the user receives the touch input from the icon 213, the real-time screen sharing chat request confirmation message 220 may be displayed before transmitting the message for requesting the real-time screen sharing chat to the terminal 2 (or the service server) . In this context, the message may be displayed in the form of a pop-up window to inform the user of specific information related to the real-time screen sharing chat or to receive selection input according to specific information from the user. Hereinafter, for convenience of explanation, a pop-up window will be described as an example.

Also, after transmitting a message for requesting the real-time screen sharing chat to the terminal 2 (or the service server), until a response message (acceptance / rejection / non-acceptance) for the request message is received from the terminal 2 (or the service server) The terminal 1 may display a pop-up window 230 among the real-time screen sharing chat requests. In other words, when the terminal 1 receives a touch input from the user on the icon 213, the terminal displays the real-time screen sharing chat request confirmation pop-up window 220 and receives the confirmation input (YES) (Or accepting / rejecting / rejecting) a response message to the request message from the terminal 2 (or the service server) until the pop-up window of the real-time screen sharing chat request is received (230) can be displayed. On the other hand, upon receiving a cancel input ('cancel') of the user in the real-time screen sharing chat request confirmation pop-up window 220, the terminal 1 cancels (stops) the real-

Upon receiving the real-time screen sharing chat request message from the terminal 1, the terminal 2 (or the service server) determines whether or not the terminal 2 can perform a real-time screen sharing operation during chatting. 2 (or the service server) transmits a response message to the terminal 1 that the real-time screen sharing chat operation is impossible. Here, the terminal 2 (or the service server) can determine whether or not a real-time screen sharing chat is possible through whether an application (or a program) for supporting a real-time sharing chat operation is installed in the terminal 2. When the terminal 1 receives a response message indicating that the real-time screen sharing chatting is not possible from the terminal 2 (or the service server), the terminal 1 displays the real-time screen sharing chat unavailable pop-up window 240 and the real-time screen sharing chatting procedure ends.

If the terminal 2 can perform a real-time screen sharing operation during a chat, the terminal 2 displays a real-time screen sharing chat request pop-up window 260. At this time, the terminal 2 receives the real-time screen sharing chat request message from the terminal 1 from the service server, and can display the real-time screen sharing chat request pop-up window 260. When the terminal 2 receives the acceptance input of the user (YES), the terminal 1 and the terminal 2 complete the connection for the real-time screen sharing chat and share the real-time screen and perform the chatting. On the other hand, when the terminal 2 receives the rejection input ('NO') of the user, the terminal 2 transmits a response message to the terminal 1 denying the real-time screen sharing chat, and the real-time screen sharing chatting procedure ends.

A translucently displayed chat window means a window for displaying a chat message (content) input by each terminal in chat and an input time of a chat message, sorted by terminal and displayed in chronological order. The terminal can output a plurality of layers overlaid on one screen. In this case, a layer displaying the chat window can be displayed at the top of the layer displaying the shared image. The translucent chat window is displayed after the connection for the real-time screen sharing chat is completed. That is, the chat contents displayed in the chat window before and after the real time screen sharing chat connection are displayed in the same manner, and the chat contents are displayed in a translucent manner after the real time screen sharing chat connection. Here, a home screen (or a home-screen image) means an image in a state in which an execution screen of an application is not displayed. That is, a state in which the terminal is displayed for the first time when the lock screen state is released may correspond to a state in which the terminal executes the application but the output image for the application is not displayed on the screen.

Chat window control icons 311 and 321, shared status display areas 312 and 322 and real time screen sharing chat related icons 313 and 323 are displayed on the screen 310 of the terminal 1 and the screen 320 of the terminal 2 . The chat window control icons 311 and 321 control the semitransparent chat window on the terminal screen or hide (or remove) the semitransparent chat window on the terminal screen. That is, when the user inputs a touch input to the chat window control icons 311 and 321 from the user while the translucent chat window is displayed, the translucent chat window is hidden, and the chat window control icons 311, 321), a translucent chat window is displayed. Accordingly, the chat window control icons 311 and 321 can be displayed at all times while real-time screen sharing chat is performed between the terminals.
