Description

  The present invention relates to a data processing method and a mobile terminal for deleting a plurality of types of data.

  Currently, various application functions such as e-mail, schedule management, camera shooting, and voice download are added to mobile terminals. As a result, the mobile terminal manages data for each function, and when there is data to be changed such as correction or deletion, the user operates the management menu for the data type.

  A conventional operation screen of the mobile terminal will be described. FIG. 4 shows an example of the operation screen.

  As shown in FIG. 4, the operation screen is hierarchized for each function from the main menu screen. <Phonebook> is an operation screen for searching for a telephone number, newly registering, correcting, and the like. <Mail> is an operation screen for creating an e-mail and browsing received mail and transmitted mail. <Schedule> is an operation screen for inputting and confirming a schedule. <Picture> is an operation screen for displaying registered moving image and still image data on the screen. <Melody> is an operation screen for playing a registered melody.

  When the user operates the portable terminal and selects any item from the <Menu> screen, an operation screen for a function corresponding to the selected item is displayed. When the user selects “shoot” from the <menu> screen, the mobile terminal executes a shooting function, and when the user selects “net connection”, the mobile terminal connects to a network such as the Internet. When the user selects “setting”, the mobile terminal displays a screen for setting various functions.

  When the user wants to operate the e-mail function, when the user selects <e-mail>, three types of options of <create new mail>, <received mail>, and <sent mail> are displayed on the screen. <New mail> is an option for opening the mail creation screen, <Received mail> is an option for displaying the contents of the received mail, and <Sent mail> is for displaying the contents of the already sent mail. Is an option for.

  Subsequently, when the user selects <Received Mail> from the three options, a list showing the data names of the stored received mails is displayed on the screen. “Received mail 1” and “received mail 2” shown in FIG. 4 correspond to data names. The user can delete unnecessary received mail by operating the mobile terminal while viewing the received mail list screen. When <Sent Mail> is selected, the sent mail can be deleted. <Received mail> and <Sent mail> operation screens correspond to the management menu screen.

As a method for managing data stored in a portable terminal, a method for efficiently deleting a telephone call history and a call history is disclosed (see Patent Document 1). If this method is applied to each function, the history of each function can be managed.
JP 2003-179679 A

  In the conventional portable terminal, as described above, various types of data are managed for each function. The method disclosed in Patent Document 1 also needs to operate a management menu for each type of data. For this reason, when a large amount of data is to be deleted due to data reduction or the like, the user needs a complicated operation of starting the management menu of each function and deleting the data. A specific example of the problem will be described.

  Here, it is assumed that the user wants to delete e-mail 1, moving image data 1 and additional melody 1 in FIG. After the e-mail 1 is first deleted by the procedure described in the background art, the portable terminal is operated to return the operation screen to the <Menu> screen. Next, select the “Picture” item on the screen, and select “Movie” on the <Picture> screen. The <Movie> screen with “Movie data 1” and “Movie data 2” as options is displayed. Is done. Operate the mobile terminal to delete “moving image data 1”. Thereafter, in order to delete the additional melody 1 of the download melody, the user needs to return the operation screen to the <Menu> screen once and perform the same operation as that for deleting the moving image data 1. Even if only the above three data are deleted, the operation screen changes at least 10 times, and the number of operations accompanying screen switching increases.

  The above problems are caused by the difficulty in integrating the development work of each function with the increase in the number of functions of mobile terminals and the increase in development scale, and the provision of an interface that is easy to use for the user.

  The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide a data processing method and a mobile terminal that can delete data in the mobile terminal in an integrated manner. To do.

The data processing method of the present invention for achieving the above object is a data processing method of a portable terminal in which a plurality of different types of data are stored in a storage unit due to a difference in application function,
A list in which data names of the plurality of data are registered is stored in the storage unit;
When an instruction to delete data is input, a list of the data names registered in the list is displayed on the output unit,
When a data name is selected from the list, data specified by the selected data name is deleted from the storage unit.

  In the present invention, a list in which individual data names are described for a plurality of different types of data corresponding to the application function is displayed on the output unit, and data having a data name selected from the list is deleted. Therefore, even if the data to be deleted is a plurality of different types of data, it is possible to delete a plurality of types of data collectively by selecting their data names.

  According to the present invention, it is possible to erase different types of data collectively in correspondence with a plurality of types of application functions, so there is no need to operate a management menu for deleting data for each function, The user's effort is reduced.

  The portable terminal of the present invention displays a list of data names for a plurality of different types of data depending on the application function, and when a data name is selected from the list, the data corresponding to the selected data name is displayed. Is to be deleted. Examples of the portable terminal according to the present invention will be described below.

  The configuration of the mobile terminal of this embodiment will be described. In this embodiment, a data processing method related to the present invention will be described in detail, and normal functions such as a telephone function, an e-mail function, and a network connection function are the same as those in the past, and thus detailed description thereof will be omitted. To do.

  FIG. 1 is a block diagram illustrating a configuration example of a mobile terminal according to the present embodiment. FIG. 2 is a diagram illustrating an example of an operation screen of the mobile terminal according to the present embodiment. As shown in FIG. 2, the operation screen is hierarchized for each application function.

  As shown in FIG. 1, the portable terminal of this embodiment includes an input unit 1 including a plurality of keys for a user to input instructions, a storage unit 2 that stores various data, and a processing unit that operates under program control. 3 and an output unit 4 of a display device for displaying data stored in the storage unit 2.

The storage unit 2 stores data groups 22 _{1 to} 22 _{n for} each function. n is an integer of 2 or more indicating the number of types of data to be classified. In the example shown in FIG. 2, the data is classified into seven types such as received mail and download melody. Regarding melody data, in this embodiment, two types of cases are shown: an initial registration melody that is a melody registered in advance when the mobile terminal is shipped, and a download melody that is a melody additionally registered by the user via a network.

Each of the data groups 22 _{1 to} 22 _n corresponds to each type of data such as received mail, moving image, still image, melody, schedule, and the like shown in FIG. When the received mail data is the data group 22 ₁ , the moving image data corresponds to the data group 22 ₄ , and the still image data corresponds to the data group 22 ₅ . Each of the data groups 22 _{1 to} 22 _n is not limited to a plurality of data, but may be a single data group.

  Although not shown in FIG. 2, the data group is not limited to the above seven types, and there may be a data group for collecting data management information (information such as folders and control rules). Further, there may be a data group for registering the incoming call history and outgoing call history.

Further, in the present embodiment, the storage unit 2 stores a erasable data list 21 including information on data that can be deleted by a user operation among the data groups 22 _{1 to} 22 _n . The deleteable data list 21 includes, for each data that can be deleted by the user, a data name, a data type, link information to the data group, and information indicating whether or not a PIN number is required to be deleted. Related information is registered. Each time new data is registered in the storage unit 2 by the user, the processing unit 3 adds the data related information of the new data to the erasable data list 21.

  The <Data Delete> screen in FIG. 2 corresponds to a list of data names that do not require input of a personal identification number among the data in the erasable data list 21. The password is input in advance by the user and registered in the storage unit 2.

In the <DATA DELETION> screen in FIG. 2, data names of data that can be deleted by the user from the received mail 1 to the additional melody 2 are displayed. In the data groups 22 _{1 to} 22 _n shown in FIG. 2, the initial registration melody is data that cannot be deleted by the user. Therefore, the initial melody 1 and the initial melody 2 are not displayed on the <DATA DELETION> screen. Further, as data requiring the input of a personal identification number, for example, telephone book data can be considered.

The processing unit 3 includes a CPU (Central Processing Unit) (not shown) that executes predetermined processing according to a program, and a memory (not shown) for storing the program. The processing unit 3 includes an integrated deletion menu unit 31, a deletion process distribution unit 32, and data management units 33 _{1 to} 33 _n . Various means are virtually comprised in a portable terminal because CPU runs a program.

  The integrated deletion menu means 31 displays the data name of the deleteable data list 21 on the output unit 4 and identifies the deletion target data selected by the user. When the item “DATA DELETION” is selected by the user from the <MENU> screen shown in FIG. 2, the integrated deletion menu means 31 is activated and displays on the output unit 4 a request for input of a personal identification number. In FIG. 2, illustration of the password input screen is omitted.

  When the number is input by the user, the integrated deletion menu means 31 checks whether or not the input number matches the registered password, and if these numbers match, the deleteable data list All the data names included in 21 are displayed on the output unit 4. The screen displayed at this time corresponds to the <DATA DELETE> screen in FIG.

  On the other hand, after notifying the user of the input request for the password, if no number is input or if the input number does not match the registered password, it can be deleted by referring to the deleteable data list 21. Of the data included in the data list 21, the data name of data that does not require the input of a password is displayed on the output unit 4.

  After that, when the data name is selected by the user, the integrated deletion menu means 31 reads the deletion target data information including the selected data name and link information of the data from the deleteable data list 21 and deletes the deletion process distribution means. Pass to 32. Further, the data related information corresponding to the selected data name is deleted from the deleteable data list 21 and the updated deleteable data list 21 is displayed on the output unit 4.

  Upon receiving the deletion target data information from the integrated deletion menu unit 31, the deletion process distribution unit 32 specifies the data group from the link information, passes the data name to the data management unit of the specified data group, and requests the deletion process. .

Each of the data management units 33 _{1 to} 33 _n is a management unit that performs a process of deleting data included in each of the data groups 22 _{1 to} 22 _n . When each data management unit receives the data name of the data to be deleted, the data management unit deletes the data specified by the data name from the storage unit 2.

  Next, the operation procedure of the mobile terminal according to the present embodiment will be described in detail. FIG. 3 is a flowchart showing the operation procedure of the portable terminal of this embodiment.

  When the user operates the input unit 1 and selects “DATA DELETE” from the <MENU> screen, the processing unit 3 activates the integrated deletion menu means 31. Then, the output unit 4 displays a display requesting the input of the password (step 101).

  Subsequently, the integrated deletion menu means 31 determines whether or not a number has been input (step 102). If a number has been input, it is checked whether or not the input number matches the registered personal identification number (step 103). If these numbers match, all the data names included in the erasable data list 21 are displayed on the output unit 4 (step 104).

  On the other hand, if the number is not input in step 102 or the number input in step 103 does not match the registered personal identification number, the deleteable data list 21 is referred to. Of the data included in the erasable data list 21, the data name of data that does not require the input of a password is displayed on the output unit 4 (step 105).

  Thereafter, the user operates the input unit 1 to select the data name of data to be deleted. At that time, a plurality of data names may be selected. When the data name is selected (step 106), the integrated deletion menu means 31 refers to the deleteable data list 21, and deletes the deletion target data information including the selected data name and link information of the data. Pass to means 32.

When the deletion process distribution unit 32 receives the deletion target data information from the integrated deletion menu unit 31, the deletion process distribution unit 32 specifies the data group from the link information (step 107), and the data management unit 33 _k (k is 1 from the specified data group). any integer) to activate the one of the n, to request the deletion process by passing the data name to the data management means 33 _k.

  When a plurality of data are to be deleted and there are a plurality of types of data groups, there are a plurality of data management means to be activated. In this case, the deletion processing distribution unit 32 makes a data deletion request to the data management unit in correspondence with the type of data group of the data to be deleted, and therefore repeats the data deletion request by the number of types of the data group.

Upon receiving the data name and the deletion request instruction, the data management unit 33 _k deletes the data corresponding to the data name from the data group 22 _k in the storage unit 2 (step 108). When there are a plurality of types of data to be deleted, when the deletion process is completed in all of the corresponding data management units, the operation of the deletion process distribution unit 32 ends. The integrated deletion menu means 31 deletes the data related information of the data to be deleted from the deleteable data list 21 and displays the updated deleteable data list 21 on the output unit 4 (step 109). Thereafter, the process returns to step 106, and if the user selects a data name to be deleted, the processing from step 107 to step 109 is performed, and if the user performs another operation, the data deletion operation is terminated.

  In the data processing method of the present embodiment, the number of times of switching the operation screen including the input screen for the personal identification number is only two, regardless of the number of types of data to be deleted. Since the number of switching operation screens is smaller than before, the number of operations associated with the screen switching is smaller than before.

  As described above, according to the data processing method of the present embodiment, data over a plurality of types of functions in the mobile terminal can be deleted with a single interface. Since it is possible to erase data collectively over a plurality of types of functions, it is not necessary to operate a management menu for deleting data for each function, thereby reducing the labor of the user.

  Conventionally, even after starting the management menu, it has been difficult for general users to distinguish between data that can be deleted and data that cannot be deleted in advance prepared by the manufacturer of the portable terminal. In the present embodiment, by excluding from the list of data names displayed for data that cannot be deleted by the user or data registered in advance by the manufacturer, a burden is imposed on the user to determine whether or not the data can be deleted. I won't let you.

  Further, conventionally, depending on the type of data, there is a case where an input of a personal identification number is requested at the time of data deletion, and the user has to input a personal identification number every time data of a different type is to be deleted. In this embodiment, the user is required to input a password only before displaying a list for deleting a plurality of types of data, so that it is not necessary to input the password a plurality of times.

  Before displaying the list on the output unit 4, it is possible to prevent important data from being deleted by a person other than the user by confirming whether or not the user is the user himself / herself by the personal identification number. In the present embodiment, input of a personal identification number is requested before the list is displayed, but input of a personal identification number may be requested when the integrated deletion menu means 31 is activated. Further, if it is set in advance so that only data that does not have a problem even if it is deleted, it is not necessary to manage it by inputting a personal identification number.

  Furthermore, on the side that develops each function of the mobile terminal, it is only necessary to provide a registration processing or extraction method to the list of data that can be deleted and an interface for deletion, and it is possible to perform independent development for each function. Become.

  In the present embodiment, the case of a mobile phone having a wireless telephone function has been described. However, a mobile terminal not having a telephone function may be used. Unlike desktop and notebook PCs (personal computers), mobile terminals have a limited display size, so there are restrictions on data deletion methods. As described in this embodiment, each mobile device has a different function. This is because it is often necessary to delete data. The output unit 4 may be a printer device.

  In this embodiment, data is added to the erasable data list 21 when newly registering data. However, data related information is extracted from the newly registered data when the <Data Delete> menu screen is activated. May be added to the deleteable data list 21.

  Further, the display format of the information extracted from the erasable data list 21 on the output unit 4 may be either a list type or a tree type, and the display content is not limited to the data name but also displays the type of data. It may be.

  Furthermore, the data content of the selected data name may be previewed on the output unit 4 by the user operating the portable terminal on the <DATA DELETION> screen. This can be done by the processing unit 3 specifying data from the data name using the link information described above. By performing the preview, the user can confirm again whether or not the data is necessary.
