The present invention relates to an apparatus and method for providing location and direction information for a mobile communication terminal, and more particularly, to an apparatus and method for providing position and direction information visually and variously between mobile communication terminals. .

Recently, with the popularization of mobile communication terminals, various services such as location information service, wireless internet service for providing various types of information after basic voice call, text and voice message transmission have been provided to mobile communication terminal users.

Among these, the positioning service using a mobile communication terminal may be implemented by a method using a cell location registered in a home location register (HLR) and a method using location information by a global positioning system (GPS). In addition, there are a network-based method and a method based on a dedicated network, and a method of calculating the position of a mobile communication terminal by measuring the angle of arrival of a signal input from the mobile communication terminal (AOA: Angle Of Angle), There is also a method using time of arrival (TOA), or a hybrid method using a combination of the two methods for more accurate positioning.

For example, when a user wants to know his / her current location, and requests information on his / her location, that is, the current location information of the mobile communication terminal, using his mobile terminal, the mobile communication terminal For example, the current location information, such as simple location information divided by the same unit in the administrative district, may be provided in a text or map format.

Herein, the internal block diagrams of the user terminal 100 and the target terminal 110 are the same.

On the other hand, although both the user terminal 100 and the target terminal 110 can confirm the position and direction of each other, in the following description, for example, the position information on the target terminal 110 is displayed on the user terminal 100 as an example. Explain.

First, the controller 200 typically performs overall control operations of the terminals 100 and 110 such as performing wireless calls and data processing of the terminals 100 and 110. The controller 200 updates the screen according to the location information obtained through the above-described method in the location information display screen mode according to an embodiment of the present invention.

In particular, the control unit 200 determines the density and placement position of the visual item representing the distance and direction between the user terminal and the target terminal according to the location information provided in real time, and thereby visually expresses the visual item on the screen. Perform the function. Here, the location information refers to information indicating in which direction and how far the target terminal 110 is located based on where the user terminal 100 is located.

In addition, the control unit 200 according to the present invention detects the direction of the user terminal 100 in accordance with the signal through the geomagnetic sensor from the sensor unit 270 calculates the result value, and provides the calculated result value in real time Along with the location information to be applied, the density and placement position of the visual item is applied. Accordingly, the controller 200 calculates the contents of the screen displayed on the display 110 in response to the determined density and position of the visual item and controls to continuously update the screen. That is, the controller 200 controls the screen to be updated by providing the display unit 210 with screen data calculated using the location information and the result value according to the direction of the user terminal.

In this way, even if the user tilts his terminal, a visual item indicating the direction of the location where the other terminal is located can be displayed on the screen.

 The display unit 210 receives and displays display data on key input data input from the key input unit 220 under the control of the controller 200, or displays the operation state and a plurality of information of the mobile communication terminals 100 and 110.

In addition, the key input unit 220 includes various keys including numeric keys to provide the control unit 200 with key input data input by the user. That is, the key input unit 220 outputs its own key input data according to the input of each key provided, and the key input data output from the key input unit 220 is applied to the control unit 200 so that such key input data is stored. It is detected that the key input data according to the key input, the control unit 200 performs the operation according to the result.

In addition, the memory 230 connected to the controller 200 may include a read only memory (ROM) and a random access memory (RAM) for storing a plurality of programs and information necessary for controlling operations of the terminals 100 and 110. , Voice memory and the like. In addition, according to an embodiment of the present invention, various visual items, including basic visual items, may be additionally downloaded and stored in the memory 230.

In addition, the RF module 250 transmits / receives an RF signal with a base station through an antenna ANT. The RF module 250 converts the received RF signal into an IF (Intermediate Frequency) signal and outputs the signal to the baseband processor 240 and the baseband processor ( The IF signal input from 240 is converted into an RF signal and transmitted. The baseband processor 240 is a baseband analog ASIC (BAA) that provides an interface between the controller 200 and the RF module 250. The baseband processor 240 converts a baseband digital signal applied from the controller 200 into an analog IF signal. It is applied to the RF module 250, and converts the analog IF signal applied from the RF module 250 into a digital signal of the baseband and applies it to the control unit 200. And according to the first embodiment of the present invention may be provided with the location information received from the server 135 via the RF module 250.

In addition, according to the second embodiment of the present invention, each terminal 100 and 110 includes a GPS receiver 260 that receives a GPS signal received from the GPS satellites 105. Then, the controller 200 calculates the location information of the target terminal 110 through the signal provided from the GPS receiver 260.

On the other hand, the terminal 100, 110 according to the present invention further includes a sensor unit 270 for detecting the degree of rotation direction. Sensor unit 270 according to an embodiment of the present invention means a geomagnetic sensor.

Therefore, when the sensor unit 270 receives a detection signal indicating the rotation of the terminals 100 and 110 detected by the geomagnetic sensor in a predetermined direction, the sensor unit 270 distinguishes the rotation directions of the terminals 100 and 110 and determines a result value according to the classification. It is configured to be connected to the control unit 200 to calculate.

Next, the control operation in the control unit 200 will be described with reference to FIG. 3. 3 is a control flowchart illustrating a process of controlling a location information display screen according to changed location information according to an exemplary embodiment of the present invention.

First, the control unit 200 receives information on the target terminal 110 to know the location information through the key input unit 220 of the user terminal 100 in step 300 and registers it in the terminal 100. . Also, in another embodiment of the present invention, information about the target terminal 100 may be registered in advance in the server 135.

Then, the control unit 200 monitors the location information, that is, the correct distance and direction with respect to the target terminal 110 in step 310. Then, the controller 200 calculates the location information between the user terminal 100 and the target terminal 110 by using the location information provided in real time from the server 135 or the GPS satellite 105 in step 320. In other words, the controller 200 calculates the direction of the location where the target terminal 110 is located based on the distance difference between the user terminal 100 and the target terminal 110 using the location information provided. do. Then, the controller 200 continuously updates the screen according to the position information calculated in step 330.

Here, a visual item is displayed on the updated screen to visually and vividly express the location information. In detail, the density of the visual item displayed on the screen is determined according to the distance from the target terminal 110, and the position of the visual item on the screen is determined according to the direction of the target terminal 110.

Meanwhile, the visual item may be selected by the user according to his or her taste. This visual item setting process will be described with reference to FIG. 4. 4 is a control flowchart for visual item setting according to an embodiment of the present invention.

 First, the control unit 200 determines whether there is a key input for selecting a visual item menu for setting a visual item from the user in step 400. If the visual item menu is selected by the user, the control unit 200 proceeds to step 410 to display the visual item list. For example, a visual item refers to a conventional icon such as a flower blossom or an arrow. Then, the controller 200 determines in step 420 which one of the visual items is selected by the user.

As a result of the determination, when any one visual item is selected by the user, the controller 200 proceeds to step 430 and displays the selected visual item on the screen. In this case, only one visual item may be displayed or the selected visual items may be displayed at different densities. In particular, the density of a visual item according to an embodiment of the present invention may be expressed as the number of visual items displayed on the screen and the density of the visual item color.

Then, the controller 200 determines whether the visual item selection currently displayed by the user is completed in step 440. Therefore, when the selection is completed with the visual item currently being displayed, the control unit 200 proceeds to step 450 to set the selected visual item as the basic visual item. Accordingly, the location information display screen may display the location and direction of the target terminal 110 using the set visual item.

Then, referring to FIG. 5 to describe in more detail the process of updating the location information display screen according to the above-described location information change in FIG. 3. FIG. 5 is a control flowchart illustrating a process of updating the location information display screen according to the change of location information in FIG. 3.

Referring to FIG. 5, the controller 200 determines whether a location information display screen mode for displaying a counterpart's position and direction through a visual item is selected in operation 500. In other words, it is determined whether a predetermined key for switching the current mode to the location information display screen mode in the standby state is input.

If a predetermined key is input by the user to switch to the location information display screen mode, the controller 200 proceeds to step 505 to determine whether there is a preset visual item. If there is no visual item preset by the user, the control unit 200 proceeds to step 510 to load the basic visual item from the memory 230. On the contrary, if there is a visual item preset by the user in step 505, the control unit 200 proceeds to step 515 to load the preset visual item from the memory 230.

Then, the controller 200 starts to monitor the position and direction of the target terminal 110 in step 520. Here, the controller 200 receives location information from the server 135 or the GPS satellite 105 according to the location and direction monitoring of the target terminal 110. Then, the control unit 200 proceeds to step 525 to calculate the correct position and direction information using the received position information. That is, it is calculated how far the target terminal 110 is located from the user terminal 100 and in which direction.

The control unit 200 determines the screen on which the visual item is placed according to the position information calculated through the above method. In detail, the density of the visual item is determined according to the distance between the user terminal 100 and the target terminal 110, and the position at which the visual item is displayed on the screen is determined according to the direction in which the target terminal 110 is located. do. When the arrangement screen of the visual item is determined as described above, the controller 200 displays the arrangement screen on the display unit 210 in operation 535. Then, the control unit 200 determines whether another function is selected by the user in step 540.

In other words, unless another function is selected by the user in step 540, the process from step 520 to step 535 is repeatedly performed, and thus the location information on the user terminal 100 is The display screen changes according to the movement of the other party. Therefore, the present invention can emotionally express the place where the other party is located by using a visual item indicating the position and direction, even if the other party is not in direct communication with the interested party, and the distance between each other in real time through the screen on which the visual item is displayed. By visualizing the direction, the user can grasp the movement of the other party at a glance.

Next, the foregoing will be described in more detail with reference to FIGS. 6A to 6C. 6A to 6C are screen exemplary views illustrating a screen updated according to a change of location information according to an exemplary embodiment of the present invention. In particular, FIGS. 6A to 6C illustrate screens in which the location information display screen is updated as a counterpart having a target terminal 110 registered as a target of interest moves.

First, as shown in FIG. 6A, a visual item is displayed at the lower left of the location information display screen when the other party is located southwest within a radius of 7 km. At this time, the distance between the user and the counterpart is expressed by the density of the visual item, and the density is expressed by the number of visual items and the density of colors. That is, the closer the distance to the other party, the higher the density of the visual item is displayed. As the distance increases, the number of visual items is increased to display and the color of the visual item is also displayed darker. Therefore, the density of a visual item according to an embodiment of the present invention is an expression method for emotionally representing a near and far distance of an opponent.

For example, when the visual item is set to a flower blossom as shown in FIG. 6A, and the other party is located southwest within a radius of 7 km, the location information display screen displays about 1 flower flower, which is a visual item, in the southwest direction, and the flower color is pale. It is colored. In addition, the distance to the other party may be displayed at the bottom of the screen to inform the user of the more accurate distance.

Subsequently, as the counterpart approaches the user from the southwest, as shown in FIGS. 6A to 6C, the screen is periodically updated and displayed as if the blossoms are gradually blooming one by one.

Thereafter, when the other party approaches from the southwest to within a radius of 3 km, as shown in FIG. 6B, the location information display screen is displayed as more blossoms are gradually blooming, and the blossom color is also displayed more intensely than in FIG. 6A. Subsequently, when the other party continues to approach within a radius of 1 km, a darker and larger number of flowers are displayed on the location information display screen as shown in FIG. 6C. According to the density and position of the visual item displayed as described above, the user can perceive the presence of the other party emotionally.

 On the other hand, the bar has been described only when the user is holding the terminal fixedly and the user's eyes and the terminal screen facing each other, in another embodiment of the present invention will be described a case in which the user turns the terminal screen. That is, below, an example of controlling the location information display screen according to the direction of the user terminal will be described.

To this end, referring to FIG. 7, which is a control flowchart for explaining a process of updating a screen corresponding to a direction of a user terminal according to another embodiment of the present invention. In addition, the process of FIG. 7 will be described with reference to FIGS. 8A to 9B to explain in detail. 8A to 8B are screen exemplary views showing an example of a screen that changes in response to a direction of a user terminal according to an embodiment of the present invention, and FIGS. 9A to 9B are directions of a user terminal according to an embodiment of the present invention. A screen example showing another example of a screen that is changed in correspondence with the.

First, when the user switches to the location information display screen mode, the controller 200 initializes the screen to the location information display screen. When the location information display screen mode is performed, the controller 200 receives location information on the target terminal 110 in step 700. Then, before determining the screen on which the visual item is placed using the location information, it is determined whether the direction of the user terminal 100 is changed in step 710. That is, it is determined whether the user terminal 100 is turned in a predetermined direction by the user.

Here, the controller 200 calculates the direction of the user terminal 100 by using a signal input from the sensor unit 270 using a geomagnetic sensor. This is to display the direction in which the target terminal 110 is located on the screen, regardless of the rotation, even if the user rotates his terminal and sees it at an angle.

If the direction of the user terminal 100 is not changed in step 710, the controller 200 calculates a basic direction value of the user terminal in step 720. In contrast, when the direction of the user terminal 100 is changed, the controller 200 calculates the direction of the user terminal 100 to determine in which direction how much the user terminal 100 has rotated in step 730.

Then, the controller 200 calculates a location information display screen to display a visual item indicating a distance and a direction of the target terminal 110 by using the result value and location information calculated in step 740. In operation 750, unless another function is selected, the controller 200 continuously updates the location information display screen as the calculated result value and the location information are changed. That is, the controller 200 determines the content of the screen to be displayed next based on the calculated result value and position information.

For example, as illustrated in FIG. 8A, the target terminal 110 is located north of the user terminal 100, and when an arrow item, which is a visual item, is displayed on the location information display screen, the target terminal 110 of the user terminal 100 is displayed. The location information display screen on the terminal having a direction of 90 ° is displayed so that the arrow shape is perpendicular to the lower side of the screen. That is, the arrow-shaped arrow direction is displayed facing the north where the target terminal 110 is located.

On the contrary, when the target terminal 110 is located at the north side of the user terminal 100 and the direction of the user terminal 100 is turned to the right by 45 ° as shown in FIG. 7B, the control unit 200 has the arrow direction of the screen. The screen is calculated and generated so that it is displayed obliquely at an angle of 45 ° from the left to the right with respect to the lower side. Accordingly, even if the user rotates his terminal and sees it at an angle, the screen always displays the direction in which the target terminal is actually located.

If it is assumed that the position information per second is periodically received and the screen is updated every second, the density and placement position of the visual item may be determined as much as the calculated position information and the calculated result value each time. Through this process, the location information display screen of the user terminal is changed by the result value according to the location information and the direction of the user terminal.

8A to 8C described above, the visual item is an arrow shape, and the screen for displaying the opponent's position by varying the number and arrangement of the arrow shape is taken as an example, but an example of a compass screen is shown in FIGS. 9A to 9B. . In the compass screen as shown in FIGS. 9A to 9B, the compass needle may be changed depending on the direction where the target terminal 110 is located and the direction of the user terminal 100. Here, the visual item corresponds to a compass needle, and the distance to the opponent is displayed as a number at the bottom of the screen rather than the density of the visual item. By doing so, the user viewing the location information display screen always sees the compass screen pointing to the other party regardless of the direction of his terminal.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. For example, FIGS. 8A to 9B illustrate examples in which embodiments of the present invention can be applied, and the present invention is not limited to the above-described embodiments. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below, but also by the equivalents of the claims.

As described above, according to the present invention, as the distance and direction between the user and the counterpart are changed in the mobile communication terminal, the user's special needs may be satisfied by controlling the density and movement of the visual item and displaying the same on the screen. In addition, according to the present invention, since the screen of the user terminal is changed according to the distance and direction of the other terminal, it is possible to give a variety of changes to the location information display screen to have fun for the user.
