[ This will be useful for editing the image displayed on the display unit 151. [

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be, for example, activation or deactivation of the display unit 151 or the touch pad.

Hereinafter, embodiments of a method that can be implemented in a terminal configured as above will be described with reference to the accompanying drawings. The following embodiments can be used alone or in combination with each other. In addition, the embodiments described below may be used in combination with the above-described user interface (UI).

2 is a flow chart illustrating a method according to a first embodiment of the present invention.

2, in the method according to the first embodiment of the present invention, the user can easily know which of the icons of the application displayed on the screen is the application using the data service. . For this purpose, an icon of the application using the data service is displayed together with a specific indicator indicating that the data service is being used. Specifically, it is as follows.

First, when entering the idle screen mode (S101), the control unit 180 checks whether there is an application running in the background (S102). At this time, entering the idle screen mode may be canceled from the screen locked state. Or entering the idle screen mode may be that the specific application is being executed and the idle screen is displayed by removing the specific application screen. Or entering the idle screen mode may be that the specific application is running in the foreground and the idle screen is displayed by changing the specific application in the background.

If there is an application running in the background, the control unit 180 checks whether there is an application using the data service (S103).

There are various ways to check whether there is an application using the data service. First, in order to use the data service, an application may have to use a specific API (Application Programming Interface). The specific API may be one of the mobile communication module 112, the wireless Internet module 113, and the short-range communication module 114. Therefore, the control unit 180 can check whether there is an application that uses the data service by checking whether there is an application in which the specific API is used.

Alternatively, the mobile communication terminal 1000 may have a function of monitoring the usage status of the data service. Therefore, the control unit 180 can confirm whether there is an application using the data service from the function.

If it is determined that there is an application using the data service, a specific indicator is displayed together with the icon of the application using the data service (S104). In other words, an icon of various applications is displayed on the idle screen, and a specific indicator can be added to the icon of the application using the data service so that the application using the data service can be distinguished from the application using the data service . The form of the specific indicator will be described later with reference to FIG. 3 to FIG.

FIG. 3 is an exemplary view showing an example of the first embodiment of the present invention, and FIG. 4 is an exemplary view showing another example of the first embodiment of the present invention.

As can be seen from Figs. 3 and 4, when the screen is released from the locked state and the idle screen is displayed or the specific application which is being executed is terminated, the screen of the specific application disappears and the idle screen is displayed, The icon for the applications installed in the mobile communication terminal 100 is displayed when the specific application screen disappears and the idle screen is displayed by changing the specific application running in the foreground in the background.

At this time, for the application using the data service, a special symbol (e.g., " @ ") or a special image may be displayed on the corresponding icon as shown in FIG. The special symbol or the special image may be displayed at the upper left corner of the icon or at the upper right corner as shown in FIG. Alternatively, the special symbol or the special image may be displayed at an arbitrary position in the lower part of the icon.

By displaying the special symbol or the special image in this manner, the user can easily distinguish between the application using the data service and the application using the data service. Thus, the user can know whether or not a particular application that he / she does not intend to use continues to use the data service, thereby terminating the specific application. For example, suppose a user runs a first application in foreground, then changes it in the background, runs a second application, and then terminates the second application. After that time, the user can not easily know whether the first application is still running or not. To understand this, it is cumbersome to execute an application for managing running applications separately. However, even if the management application is executed as described above, there is a problem that it is not easy to know what application is currently using the data service. On the other hand, if a special symbol or a special image is displayed on the icon of the application using the data service as in the first embodiment of the present invention, the user can know whether or not to use the data service more conveniently.

5 is an exemplary view showing a modification of the first embodiment of the present invention.

As can be seen from FIG. 5, when the screen is released from the locked state to display the idle screen, or the specific application which is being executed is terminated, the screen of the specific application disappears and the idle screen is displayed. The amount of data transmitted and received by the specific application can be displayed when the user selects an icon of the specific application in a state where the screen of the specific application disappears and the idle screen is displayed by changing the specific application in the background.

At this time, the amount of data transmitted and received by the specific application may be time, specific time period, daily, or monthly. Or the amount of data may be a cumulative amount since the user has run the application. Alternatively, the amount of data may be the amount of data transmitted and received while operating in the background. At this time, when the background is switched back to the foreground, the amount of the data may be flushed.

Thus, by displaying the amount of data transmitted and received by the application together with the icon, the user can more conveniently understand the data service usage status.

6 is an exemplary view showing another modification of the first embodiment of the present invention.

As can be seen with reference to FIG. 6, statistics on the amount of data sent and received by applications may be displayed along with icons. The statistics on the amount of data sent and received can be displayed only for applications that can use the data service.

The statistics can be represented by a bar graph. Alternatively, the statistics may be expressed in numbers. Alternatively, the statistics may be time, specific time period, daily, or monthly. Alternatively, the statistics may be accumulated after the screen lock is set.

By displaying the statistics of the amount of data transmitted and received by the application along with the icon of the application, the user can more conveniently know the data service usage status

7 is an exemplary view showing a method according to a second embodiment of the present invention.

7, when a specific application is executed in the foreground, a specific symbol or a specific image (e.g., an arrow mark or an hourglass mark) indicating whether the specific application is using the data service is displayed as a status Line. The status indicator may be displayed at the top of the display unit of the mobile communication terminal as shown in FIG. Alternatively, the status bar may be displayed on the right / left side of the display unit of the mobile communication terminal.

Further, according to the second embodiment of the present invention, statistics of data transmitted and received by the application together with the specific symbol or the specific image or alone can be displayed. The statistics may be hourly, daily, or monthly as described above. Or the statistics may be accumulated after the application is changed to foreground.

Thus, when the application is executed in the foreground, a specific indicator or a specific image indicating whether the application is using the data service is displayed, and the statistics on the amount of data transmitted and received are displayed, The data service usage status can be known

FIG. 8 is a flowchart illustrating a method according to a third embodiment of the present invention, and FIG. 9 is an exemplary view showing a screen according to the method of the third embodiment of the present invention.

As can be seen from FIG. 8, when the amount of data transmitted and received by an application running in the background exceeds a predetermined threshold value, the user is notified so that the user can easily know whether or not the data service is used . Specifically, the following description will be given.

First, the controller 180 of the mobile communication terminal 100 checks whether there is an application running in the background (S201). The check may be performed when entering the idle screen mode. Alternatively, the check may be performed periodically.

If there is an application running in the background, the control unit 180 checks whether there is an application using the data service (S202).

As described above, there are many ways to check whether there is an application using the data service. A description thereof will be omitted.

If there is an application using the data service, it is determined whether the amount of data transmitted and received by the application is greater than or equal to a preset threshold value (S203). The threshold value can be preset by the user.

If the amount of data transmitted and received by the application is equal to or greater than a preset threshold value, the user is notified (S204).

9, the notification may be displayed on the display unit so as to be superimposed on the idle screen. The guiding text may be superimposed over the icons of the plurality of applications so that the user can confirm the guiding text and take other actions, as shown in Fig. A button for receiving an input from the user, for example, confirmation, may be displayed along with the guidance text.

Alternatively, the notification may be to generate sound through the acoustic thrust module 152 shown in FIG. Alternatively, the notification may be generated by the alarm unit 152 or the haptic module 154 shown in FIG.

As described above, when the amount of data transmitted and received by an application running in the background exceeds a predetermined threshold value, the user is notified so that the user can prevent the unwanted application from being continuously executed.

10 is an exemplary view showing a screen according to the method of the third embodiment of the present invention.

8 and 10, if the amount of data transmitted and received by the application is equal to or greater than a predetermined threshold value, the icon of the application is subjected to special effect processing such as sound film, transparency, or highlight, .

As described above, when the amount of data transmitted / received by a specific application is a preset threshold value, the icon of the specific application is displayed by special effect processing so that the user can immediately know and can terminate the application accordingly.

11 is an exemplary view showing a method according to a fourth embodiment of the present invention.

As can be seen from FIG. 11, in the method according to the fourth embodiment, the applications that can use the data service and the applications that do not use the service are grouped and displayed separately on the idle screen.

Specifically, according to the method according to the fourth embodiment, it is checked whether each application uses a specific API (Application Programming Interface) for a data service. If there are applications using the specific API, . Icons of applications that do not use the specific API are separately grouped and displayed.

As can be seen with reference to FIG. 11, the icons of the applications that can use the data service are displayed at the top of the display unit, and the applications that do not use the data service can be displayed at the bottom.

As described above, according to the fourth embodiment of the present invention, since the icons of the applications are grouped according to whether the data service is used, the user can execute an appropriate application according to his / her data communication use status. For example, let's say you have several applications for games. At this time, let's assume that one application is a game using a data service and the other is an application that does not use a data service. If the user has a lot of data usage and is concerned about the fee, the user can select and execute a game not using the data service from among the grouped icons. Therefore, convenience for the user is increased.

As a modification of the fourth embodiment, when an idle screen is displayed, a specific indicator or a specific image is displayed for an icon of an application using the data service so as to distinguish between applications that can use data services and those that do not It may be displayed together. Or an icon of an application using the data service may be displayed with a special effect process (e.g., highlight, shading, etc.).

12 is an exemplary view showing a method according to a fifth embodiment of the present invention.

12, when the data service through the mobile communication network or Wi-Fi is impossible or excessive, icons displayed on the idle screen are subjected to special effect processing and displayed, So that the application does not need to be executed unnecessarily. Specifically, it is as follows.

For example, assume that a user has moved to an area where voice calls are possible but data services are not available, and then the user runs an application that uses the data service. The executed application will then try the data service. However, since the data service is impossible, the executed application is freezed and does not operate. Nevertheless, running the application only results in wasting the battery of the mobile communication terminal.

As another example, suppose that a user has used more than the amount of data that can be used according to his / her rate plan. In such a case, since the user can not conveniently know whether he or she has used the data in excess of the amount of data, the application using the data service is repeatedly executed, resulting in a large cost.

Therefore, in the fifth embodiment of the present invention, when the data service is impossible or when the amount of the predetermined data is exceeded, the icon of the application using the data service is displayed by special effect processing. For example, as shown, the icon of the application can be shaded and displayed or transparently displayed.

Meanwhile, the fifth embodiment of the present invention can provide an option that allows a user to set whether a specific application performs a data service using a mobile communication network or a data service using Wi-Fi. When the mobile communication terminal is set to perform the data service using the Wi-Fi, the icon of the application may be displayed with a special effect when the mobile communication terminal is in a geographical location where Wi-Fi is impossible.

As described above, according to the fifth embodiment of the present invention, when the data service through the mobile communication network or Wi-Fi is impossible or excessive, the special effect processing is performed on the icons displayed on the idle screen So that the user can selectively execute the application.

Various embodiments described up to now can be implemented in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

For example, the methods according to embodiments of the present invention may be implemented in a software program, and then stored in the memory 160 shown in FIG. 1 and executed by the control unit 180.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, May be modified, modified, or improved.
