The components shown in Fig. 1 are not essential, so that a mobile terminal having more or fewer components can be implemented.

Hereinafter, the components 110 to 190 of the mobile terminal 100 will be described in order.

The wireless communication unit 110 may include one or more modules for enabling wireless communication between the mobile terminal 100 and the wireless communication system or between the mobile terminal 100 and the network in which the mobile terminal 100 is located. For example, the wireless communication unit 110 may include a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short distance communication module 114, and a location information module 115.

The broadcast receiving module 111 receives broadcast signals and broadcast related information from an external broadcast management server through a broadcast channel. Here, the broadcast-related information means information related to a broadcast channel, a broadcast program, or a broadcast service provider. The broadcast-related information can also be provided through a mobile communication network. In this case, the broadcast-related information may be received by the mobile communication module 112. The broadcast signal and the broadcast-related information received through the broadcast receiving module 111 may be stored in the memory 160.

When the touch sensor and the display unit 151 have a mutual layer structure, the display unit 151 can be used as an input device in addition to the output device. The display unit 151 may be referred to as a 'touch screen'.

If there is a touch input via the touch screen, corresponding signals are sent to a touch controller (not shown). The touch controller processes the signals transmitted from the touch sensor, and then transmits data corresponding to the processed signals to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched.

In the case where the touch screen is electrostatic, it can be configured to detect the proximity of the sensing object by a change of the electric field along the proximity of the sensing target. Such a touch screen may be classified as proximity sensor 141. [

Here, the screen information is a graphic image that can be output on the display unit 151a, and is independent of the type.

For example, the screen information may be an execution screen of an application, an electronic document screen, a music playback screen, or an address book screen.

Next, in response to mutual proximity of the first and second terminals 100a and 100b, the first and second terminals 100a and 100b are connected via short-range wireless communication (S320).

Here, the first and second terminals 100a and 100b 'connect' can be expressed as' the first and second terminals 100a and 100b 'pair each other'. This means that the first and second terminals 100a and 100b are connected to transmit and receive information, that is, to transmit valid data.

When the first and second terminals 100a and 100b are connected as described above, the control unit 180a of the first terminal 100a is connected to the display of the first terminal 100a, Transmits data corresponding to at least a part of the screen information displayed on the display unit 151a (hereinafter referred to as "first display unit") to the second terminal 100b (S330).

For example, as shown in FIG. 4A, when the screen information displayed on the first display unit 151a includes a "mobile" telephone number, an "office" telephone number, an "email" address, and a "birthday" , The first controller 180a may transmit at least one of the included information to the second terminal 100b.

Here, the information transmitted to the second terminal 100b may be based on the user's selection or based on the information request signal received from the second terminal 100b. That is, the second terminal 100b can request the first terminal 100a with necessary information. Then, the first terminal 100a transmits the information requested from the second terminal 100b to the second terminal 100b 100b.

When data is received from the first terminal 100a, the control unit 180b of the second terminal 100b transmits a control signal to the display unit 151b of the second terminal 100b (Step S340), the first terminal 100a is located on the second display unit.

That is, the controller 180b of the second terminal determines an area of the screen display area (or display area) of the second display unit 151b that is close to the main body of the first terminal 100b.

On the other hand, the second control unit 180b uses the proximity sensor included in the second terminal 100b to provide information on the proximity of the main body of the first terminal 100b to the second display unit 151b Can be obtained.

If the area of the screen display area of the second display unit 151b adjacent to the first terminal 100b is determined as described above, the second controller 180b determines that the data received from the first terminal 100a on the identified area (S350).

In this way, by positioning the main body of the first terminal 100a in the area where the data received from the first terminal 100a is to be used in the screen display area of the second display part 151b, As shown in FIG.

4A, contact information is output on the first display unit 151a of the first terminal 100a, and mail information is displayed on the second display unit 151b of the second terminal 100b. Let's take a look at the case where the edit screen is displayed.

As shown in FIG. 4A, when information is displayed on each of the first and second terminals 100a and 100b, the first terminal 100a is connected to the second terminal 100b, The wireless communication modules of the first and second terminals 100a and 100b recognize each other. The first terminal 100a transmits information included in the screen information displayed on the first display unit 151a to the second terminal 100b such as a mobile phone number, "Address, and" birthday "date information to the second terminal 100b.

The data transmitted from the first terminal 100a to the second terminal 100b may be transmitted to the second display unit 151b of the second terminal 100b in association with an area close to the first terminal 100a .

For example, as shown in FIGS. 4A and 4B, the second display unit 151b includes a plurality of data input areas 410, 420, and 430, and data received from the first terminal 100a The first terminal 100a may be processed in association with an area in which the main body of the first terminal 100a is located, among the plurality of data input areas 410, 420, and 430. [

4C, when the main body of the first terminal 100a is close to the first area 410 (or the receiver information input area) of the second display unit 151b, as shown in FIG. 4C, An email address (mike@email.net) which is data received from the first terminal 100a in the first area 410 may be output on the second display unit 151b.

The information transmitted from the first terminal 100a to the second terminal 100b may be based on the user's selection or based on the information request signal received from the second terminal 100b. That is, the second terminal 100b can request the first terminal 100a with necessary information. Then, the first terminal 100a transmits the information requested from the second terminal 100b to the second terminal 100b 100b.

The information request to the first terminal 100a in the second terminal 100b may be made after the main body of the first terminal 100a approaches the second display unit 151b. That is, the second control unit 180b can determine which region the first terminal 100a is adjacent to, and determine data to be processed in association with the determined region. In addition, the second control unit 180b may request the first terminal 100a to transmit the determined data.

The control unit 180a of the first terminal 100b may also be configured to set a predetermined one of the plurality of data input areas 410, 420, and 430 included in the second display unit 151b, It is possible to determine the attribute of the region in which the portion is close. The first control unit 180a can transmit data corresponding to the determined attribute among the screen information displayed on the first display unit 151a to the second terminal 100b. Meanwhile, information related to the attribute may be transmitted from the second terminal 100b.

As described above, in the data communication system using the mobile terminal and the mobile terminal according to the present invention, data communication is performed corresponding to the approach of at least two mobile terminals, and furthermore, , It is possible to provide an intuitive data communication method to the user by transmitting and receiving appropriate data.

Hereinafter, a method of approving data communication will be described in detail with reference to the accompanying drawings. 5, 6A and 6B are conceptual diagrams for explaining a data transmission method in a data communication system using a mobile terminal according to an embodiment of the present invention.

In at least one of the first and second terminals 100a and 100b in the data communication system using the mobile terminal according to an embodiment of the present invention, data corresponding to the proximity of the first and second terminals 100a and 100b It is possible to determine an instruction that permits transmission and reception of data before transmission and reception.

The first control unit 180a of the first terminal 100a can determine whether the control command input to the first terminal 100a is a command that allows the second terminal 100b to transmit or receive data .

For example, the first controller 180a can perform data communication with the second terminal 100b only when a control signal corresponding to an input of a control command permitting data transmission / reception is generated.

Therefore, even if the second control unit 180a recognizes the second terminal 100b capable of short-range wireless communication using the short-range wireless signal, the control unit 180a can control the second terminal 100b, It is possible to control so that data is not transmitted or received when the user does not want to.

As an example, a control signal according to a control command that allows data communication may be generated when a predetermined portion of the first terminal 100a body is close to the second terminal 100b, as shown in FIG. 5 .

At this time, the first controller 180a may provide the user with information on the predetermined portion. For example, the information on the predetermined portion may be provided by outputting a pop-up window 520 on the first display unit 151a, as shown in FIG.

As another example, a control signal according to a control command for permitting data communication may be transmitted to the first terminal 100a by a sensing unit included in the first terminal 100a, as shown in FIGS. 6A and 6B, It can be generated when a movement pattern is detected.

For example, when the second terminal 100b is recognized, the sensing unit of the first terminal 100a may detect the position or inclination of the main body of the first terminal 100a and acquire a movement pattern of the main body .

Then, the first control unit 180a compares the sensed movement pattern with a pattern set for allowing data to be communicated. If the detected movement pattern corresponds to a predetermined pattern, the first controller 180a generates a control signal for allowing data communication with the second terminal 100b, and transmits the control signal to the second terminal 180b .

Here, the preset pattern may be a pattern stored in the first control unit 180a as a default setting, or may be a pattern set by a user's selection.

6A, when the first terminal 100a and the second terminal 100a are close to each other but the movement corresponding to the external force applied to the first terminal 100a is not applied, 100a do not perform data transmission to the second terminal 100b. 6B, when a predetermined movement pattern is applied to the main body of the first terminal 100a in a state where the first and second terminals 100a and 100b are close to each other, May transmit data to the second terminal 100b.

For example, when a pattern for tilting the main body of the first terminal 100a to a range of 90 degrees is set in a predetermined pattern, as shown in FIG. 6B, when the main body 100 is tilted to about 90 degrees by the user, The control unit 180a determines that the control command is input.

When the control command is input and the control signal is generated, the first terminal 100a is allowed to communicate data with the second terminal 100b.

As described above, the data communication system using the mobile terminal and the mobile terminal according to the present invention does not perform data communication when a control command satisfying a certain condition is not input, thereby enhancing the security of the data communication. have.

Hereinafter, a method of transmitting data from a first terminal to a second terminal will be described in detail with reference to the accompanying drawings. 7A, 7B, and 7C are conceptual diagrams illustrating a method for selecting data in a data communication system using a mobile terminal according to an embodiment of the present invention. 8A, 8B, 8C, 9A, 9B, 9C, 10A and 10B are conceptual diagrams for explaining data transmitted in a data communication system using a mobile terminal according to an embodiment of the present invention to be.

The data transmitted from the first terminal 100a to the second terminal 100b among the data corresponding to the screen information displayed on the first terminal 100a is transmitted to the first controller 180a of the first terminal 100a, Based on at least one of the determination of the first terminal 100a and the request of the second terminal 100b.

Next, a method of selecting data to be transmitted from the first terminal 100a to the second terminal 100b will be described.

For example, as shown in FIG. 7A, a plurality of images 711, 712, 713, 714, 715, and 716 are included in the screen information displayed on the first display unit 151a of the first terminal 100a At least one image 714 is selected from the user. 7B, when the main body of the first terminal 100a approaches the second terminal 100b, as shown in FIG. 7C, the first display portion 151a of the second terminal 100b The selected image 714 is output.

As described above, the first terminal 100a transmits the data selected by the user to the second terminal 100b, and the second terminal 100b transmits the selected data to the area 740 in which the main body of the first terminal 100b is close .

Next, a method for updating (or updating) information stored in the second terminal 100b based on data transmitted from the first terminal 100a will be described.

As shown in FIG. 8A, in a state in which profile information about "MIKE" is output to both the first and second terminals 100a and 100b, the first and second terminals 100a and 100b And 100b are close to each other, the first terminal 100a can transmit all data corresponding to the screen information output to the first display unit 151a to the second terminal 100b.

Then, the second terminal 100b compares the data corresponding to the screen information outputted to the second display unit 151b with the data transmitted from the first terminal 100a. As a result of the comparison, it is possible to update the data that is different or does not exist from the data stored in the second terminal 100b. For example, when the "email" address information (see 830a, 830b) is different from the "mobile" telephone number, the "office" telephone number, the "email" The second control unit 180b may update the "email" address information to the data received from the first terminal 100a, as shown in FIG. 8C (see 830'b in FIG. 8C). In this case, the second terminal 100b does not determine where the first terminal 100a is located in the second terminal 100b, and determines that the data corresponding to the screen information output to the second display unit 151b, It is possible to compare the data transmitted from the first terminal 100a as a whole and to update the data which are different or do not exist.

Next, a method of transmitting data corresponding to an area in which the first terminal 100a is close to the second terminal 100b will be described.

In the data communication system using the mobile terminal according to the present invention, the first terminal 100a can determine the data to be transmitted to the first terminal 100a according to the attribute of the area close to the second terminal 100b.

For example, as shown in FIG. 9A, the first area 910 of the first display unit 151a includes "email" address information, and the second area 920 includes an image. The second display unit 151b is divided into a plurality of areas 930, 940 and 950. The first area 930 of the plurality of areas 930, 940 and 950 receives the "email & The first control unit 180a of the first terminal 100a may be configured such that the main body of the first terminal 100a is connected to the main body of the second display unit 151b, Depending on which of the plurality of areas 930, 940, and 950 is near, the adjacent area and appropriate data can be transmitted.

As described above, the type of data transmitted from the first terminal 100a to the second terminal 100b may be based on an information request signal received from the second terminal 100b. That is, the second terminal 100b can request the first terminal 100a with necessary information. Then, the first terminal 100a transmits the information requested from the second terminal 100b to the second terminal 100b 100b.

The information request to the first terminal 100a in the second terminal 100b may be made after the main body of the first terminal 100a approaches the second display unit 151b. That is, the second control unit 180b can determine which region the first terminal 100a is adjacent to, and determine data to be processed in association with the determined region. In addition, the second control unit 180b may request the first terminal 100a to transmit the determined data.

For example, as shown in FIG. 9B, when the main body of the first terminal 100a is close to the first region 930 of the second display portion 151b, the first region 930 Data corresponding to the "email" address included in the first area 910 of the data corresponding to the screen information of the first terminal 100a may be output. 9C, when the main body of the first terminal 100a is close to the third region 950 of the second display portion 151b, the third region 950 is provided with the first Data corresponding to the image included in the second area 920 of the data corresponding to the screen information of the terminal 100a may be output.

The data transmitted from the first terminal 100a to the second terminal 100b is selectively transmitted from the first terminal 100a to the data corresponding to the adjacent region of the second display unit 151b The first terminal 100a can transmit data corresponding to the screen information to the second terminal 100b as a whole. In this case, the second terminal 100b can determine which region the first terminal 100a is close to, and then input the appropriate data to the adjacent region.

Next, a method of transmitting data based on the degree of overlap between the first and second terminals will be described.

Data transmitted from the first terminal 100a to the second terminal 100b may be based on the degree to which the first and second terminals 100a and 100b overlap (or overlap).

For example, as shown in FIG. 10A, an image is output to the first display portion 151a of the first terminal 100a, and as shown in FIG. 10b, (100a, 100b) overlap at least partially. When the first and second terminals 100a and 100b are overlapped with each other, the first and second terminals 100a and 100b of the image 1000 shown in FIG. The image 1000a may be specified on the second display unit 150. The second display unit 151b of the second terminal 100b corresponds to the specified first image 1000a as shown in FIG. The image 1000a 'may be outputted.

The degree of overlap between the first and second terminals 100a and 100b may be sensed through proximity sensors included in the first and second terminals 100a and 100b, It is possible to transmit data corresponding to the degree of overlapping of the second terminal 100b among the screen information displayed on the first display unit 151a to the second terminal 100b.

For example, the first terminal 100a may be connected to the second display 100b of the second terminal 100b, and the second terminal 100b may be connected to the second terminal 100b. The second terminal 100a can transmit data corresponding to the area overlapping with the first terminal 151b.

In this manner, the user can intuitively select data to be transmitted among the screen information displayed on the first terminal 100a using the degree of overlap of the first and second terminals 100a and 100b.

Hereinafter, a method of controlling the second terminal according to the transmission of data from the first terminal to the second terminal will be described in detail with reference to the accompanying drawings. 11A and 11B are conceptual diagrams illustrating areas in which data is received in a data communication system using a mobile terminal according to an embodiment of the present invention.

For example, the second control unit 180b of the second terminal 100b outputs data transmitted from the first terminal 100a to an area corresponding to a point where the first terminal 100a is sensed, through the proximity sensor And the highlighting of the area can be performed. The highlighting of the area may be accomplished through a variety of visual methods, such as changing the color of the area, blinking, or changing the transparency.

11A, when the first terminal 100a is detected in the first area 1110 of the second terminal 100b, the first area 1110 is highlighted, The second area 1120 can be highlighted when the first terminal 100a is detected in the second area 1120 of the second terminal 100b.

Accordingly, the user of the second terminal 100b can recognize where the data transmitted from the first terminal 100a is input.

Such an associated function may be executed automatically in response to the data being received, or may be executed after receiving approval from the user.

For example, in the second terminal 100b, if the data received from the first terminal 100a is identification information of an external terminal such as a Tell URI (Uniform Resource Identifier) such as a telephone number, ). In addition, the second terminal 100b may store the Tell URI as contact information of the external terminal.

Meanwhile, in response to the reception of data from the first terminal 100a, the function performed by the second terminal 100b may be determined according to the screen information displayed on the second display unit 151b. That is, the second control unit 180b of the second terminal 100b can perform different functions according to the screen information displayed on the second display unit 151b when the data is received from the first terminal 100a.

For example, as shown in FIG. 12A, when data corresponding to the Tell URI is received from the first terminal 100a while the home screen page is output on the second display unit 151b , The second control unit 180b can send a call to an external terminal corresponding to the Tell URI as shown in FIG. 12 (b). 12B, when data corresponding to the Tell URI is received from the first terminal 100a in a state that the contact editing screen is displayed on the second display unit 151b, The second control unit 180b may store the call URI as contact information on the memory, as shown in (b) of FIG. 12B.

As described above, the second terminal performs an appropriate function corresponding to the data received from the first terminal, so that the user can reduce the hassle of searching for and selecting a function to be executed using the received data.
