3 and 4 are flowcharts illustrating an application management process in a mobile terminal device according to an embodiment of the present invention.

In the mobile terminal device according to the present invention, FIG. 3 is a flowchart illustrating a process of managing an application according to a battery level, and FIG. 4 is a flowchart of a process of managing an application according to the usage of a central processing unit (CPU). .

First, a process of managing an application according to the remaining battery level will be described with reference to FIG. 3.

The controller 180 of the mobile terminal device determines the remaining battery level (S110). The battery remaining amount is expressed as a relative value (for example, 50%, 20%, etc.) when the battery is fully charged.

When the remaining battery level determined in step S110 is equal to or less than a first reference value (S120), that is, when the remaining battery level falls below the first reference value due to continuous use of the mobile terminal device, the controller 180 executes an application manager. A message window on whether or not is displayed on the display unit 151. Here, the application manager, which collectively refers to a series of processes for performing an application management function according to the present invention, can be understood as a kind of application or application program. The first reference value may be set to be equal to a battery remaining in a low battery state which is normally set in the mobile terminal device. For example, the first reference value may be set to a case where the battery remaining amount is 20%. When the remaining battery level determined in step S110 is greater than the first reference value, the controller 180 continuously determines the remaining battery level while maintaining the existing operation.

The controller 180 stops all or part of the running application according to the user's selection (S130). The user's selection may be input through the user input unit 130, where the user input unit 130 may be configured as a touch pad. The touch pad is a type of sensor (ie, a touch sensor 142) for detecting a touch operation, and the mobile terminal device according to the present invention includes the touch in which the display unit 151 and the touch sensor 142 form a mutual layer structure. It may include a screen. Therefore, the display unit 151 may also be used as an input device in which a user inputs data for controlling the operation of the mobile terminal device in addition to the output device. That is, the user's selection input through the user input unit 130 described above may be understood as a user's touch operation on the display unit 151.

The user's selection may be a selection regarding whether the application manager is executed or a selection regarding a part of an application set as a management target of the application manager. This will be described in detail with reference to FIGS. 5A and 5B.

When the user selects to execute the application manager, the controller 180 stops all of the applications set as the management targets among the running applications. At this time, if the running application and the application set as the management target coincide, the controller 180 stops all of the running applications. When the user selects a part of the application set as the management target, the controller 180 stops only the application selected by the user among the running applications.

Thereafter, the controller 180 continuously determines the remaining battery level (S140).

Since the user can charge the battery after the remaining battery level is lower than or equal to the first reference value in step S120 (ie, when the battery becomes a low battery), the controller 180 determines whether the remaining battery level is equal to or greater than the second reference value. It is determined (S150). The second reference value is preferably set to a value larger than the first reference value, and for example, may be set to a case where the battery remaining amount is 40%.

As a result of the determination in step S150, when the battery level is greater than or equal to the second reference value, the controller 180 controls the application that was stopped in step S130 to be rerun (S160). Re-execution of such an application may be set to re-execute all of the applications suspended in step S130 at a time, and may be set to re-execute sequentially according to a user setting, the redo of the application is preferably performed automatically. Do.

Next, a process of managing an application according to CPU usage will be described with reference to FIG. 4.

The controller 180 of the mobile terminal device determines the CPU usage (S210).

When the CPU usage determined in step S110 is greater than or equal to a third reference value (S220), that is, when the CPU usage exceeds a third reference value due to continuous use of the mobile terminal device, the controller 180 determines whether the application manager is executed. The message window relating to the display unit 151 is displayed. The third reference value refers to a heavy load state that can be typically set in relation to the CPU usage of the mobile terminal device. For example, the third reference value may be set when the CPU usage is 90%.

The controller 180 stops all or part of the running application according to the user's selection input through the user input unit 130, that is, the user's touch operation on the display unit 151 (S230). Here, the user's selection and the touch operation have the same meanings as described with reference to FIG. 3.

When the user selects a part of the application set as the management target, the controller 180 stops only the application selected by the user among the running applications.

Thereafter, the controller 180 continuously determines the CPU usage (S240).

After the CPU usage is greater than or equal to the third reference value (ie, heavy load) in step S220, a change in CPU usage may occur, such as a decrease in CPU usage due to the execution of an application, and so on. 180 determines whether the CPU usage is equal to or less than the fourth reference value (S250). The fourth reference value is preferably set to a value smaller than the third reference value. For example, the fourth reference value may be set when the CPU usage is 60%.

As a result of the determination in step S250, when the CPU usage is less than or equal to the fourth reference value, the controller 180 controls the application that was stopped in step S230 to be rerun (S260). Re-execution of such an application may be set to re-execute all of the applications suspended in step S230 at a time, and may be set to re-execute sequentially according to a user setting, the redo of the application is preferably performed automatically. Do.
