JP5541570B2 - Mail management method, mail management apparatus and mail management program in terminal device - Google Patents

Description

  The present invention relates to a terminal device represented by a mobile phone, and more particularly to mail management in a terminal device.

  Mobile phones are generally widespread because of their convenience. In addition, electronic mail (hereinafter referred to as “mail” as appropriate) is often exchanged using a mobile phone. Mails that have been transmitted or received in the past are saved as a history in a mail box on a storage device of the mobile phone.

  However, since the mobile phone has a limited storage capacity, the number of mails that can be stored in the mail BOX is usually limited to a certain number. Therefore, it is necessary to delete unnecessary mail.

  However, since selecting a mail to be deleted one by one requires a lot of effort, when the mail box capacity is exceeded, it is automatically deleted from the old ones that have not been set so that they cannot be deleted (protection settings). There is a mobile phone equipped with.

  For example, in the invention described in Patent Document 1, electronic mail received from a mail server or the like is distributed and stored in a plurality of groups according to predetermined conditions. In addition, when it is detected that there is a new mail by communication with the electronic mail server, the storage management unit notifies that there is a new mail and the total capacity of the new mail. Upon receipt of the notification, the storage management unit calculates the remaining capacity that can be added to the storage unit, and when there is a shortage, deletes the old emails preferentially from the emails of the group set to be erasable.

A featured mail management program is provided.

  According to the present invention, when the capacity of the mail BOX is exceeded, the unnecessary mail is deleted preferentially and automatically, so that the mail for which the protection setting has been forgotten disappears without causing the user to perform complicated operations. Can be prevented.

It is a figure showing the basic composition of the embodiment of the present invention. It is a figure which shows an example of the data structure of the mail automatic deletion setting information in embodiment of this invention. It is a figure showing the basic operation | movement of embodiment of this invention.

  First, an outline of an embodiment of the present invention will be described.

  As a feature of e-mails of mobile phones, there are a large number of things such as a subject alone with no body text, a body text in one line, and no content. For example, “where I am now”, “I am in XX”, “when I will return”, “I will return from now”, “OK”, etc. These emails are numerous, but they rarely look back on their contents at a later date. In the embodiment of the present invention, these mails are automatically determined as unnecessary mails and are automatically deleted, so that it is possible to prevent the mails whose protection settings have been forgotten from disappearing.

  The above is the outline of the embodiment of the present invention.

  Next, the configuration of the embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a mobile phone 1000 with a mail management function according to an embodiment of the present invention.

  The cellular phone 1000 includes a clock unit 110, a display unit 120, an operation receiving unit 130, a speaker unit 140, a microphone unit 150, a communication unit 160, a control unit 170, a storage unit 180, and a mail management function unit 190.

  The clock unit 110 is a part that manages the current date and time. The control unit 170 can grasp the current date and time by referring to the clock unit.

  The display unit 120 is a part for presenting information to the user. Specifically, the display is an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence).

  The operation accepting unit 130 is a part that accepts an operation from the user, and specifically, an operation key or the like. Moreover, the speaker part 140 is a part which outputs an audio | voice, and the microphone part 150 is a part which receives an audio | voice input.

  The communication unit 160 is a device for the mobile phone 1000 to communicate with the outside.

  The control unit 170 is a part that controls the cellular phone 1000 by an arithmetic processing unit such as a CPU, a main storage unit such as a RAM, an auxiliary storage unit storing software, and the like cooperating with each other. The function of each unit of the present embodiment is realized by the control unit 170 controlling the hardware of the mobile phone 1000.

  The mail management function unit 190 includes a mail reception unit 191, a mail transmission unit 192, a mail automatic deletion setting unit 193, a mail automatic deletion execution unit 194, and a mail automatic deletion management unit 195.

  The mail receiving unit 191 stores the mail received via the communication unit 160 in the received mail BOX 181. If the received mail BOX 181 is full at this time, the automatic mail deletion execution unit 194 is called, and then the received mail is stored.

  The mail transmission unit 192 transmits the mail created by the display unit 120 and the operation reception unit 130 by the user's operation via the communication unit 160, and then stores the created transmission mail in the transmission mail BOX 183. At this time, if the transmission mail box 182 is full, the automatic mail deletion execution unit 194 is called, and then the transmission mail is stored.

  The automatic mail deletion setting unit 193 sets automatic mail deletion setting information 194 in accordance with an input from the operation receiving unit 130 by a user operation.

  The automatic mail deletion execution unit 194 executes deletion of mail.

  The automatic mail deletion management unit 195 periodically starts the automatic mail deletion execution unit 194 according to the contents set by the automatic mail deletion setting unit 193.

  The storage unit 180 stores a received mail BOX 181, a transmitted mail BOX 182, and mail automatic deletion setting information 183.

  The received mail BOX 181 stores mail received by the mobile phone 1000. Similarly, a transmission mail BOX 182 stores a mail transmitted from the mobile phone 1000. Note that so-called draft mail (mail that was created for transmission but has not yet been actually transmitted) may be stored in the transmission mail BOX, or stored in a location other than the transmission mail BOX. You may make it exclude from the deletion object of a form.

  The automatic mail deletion setting information 183 is setting information related to the operation of this embodiment. FIG. 2 shows an example of the data structure of the automatic mail deletion setting information 183.

  The automatic mail deletion setting information 183 includes a periodic deletion flag 210, a periodic deletion execution schedule 220, a deletion exclusion period 230, and a previous execution date / time 240.

  The periodic deletion flag 210 is information regarding whether or not to delete unnecessary mails periodically. The periodic deletion execution schedule 220 is information on what intervals are used for periodic deletion. The deletion exclusion period 230 is a period for which the object to be deleted is to be excluded. The previous execution date and time 240 is the latest date and time when automatic deletion was performed.

  The periodic deletion flag 210, the periodic deletion execution schedule 220, and the deletion exclusion period 230 are set by the mail automatic deletion setting unit 193, and the previous execution date and time 240 is set by the mail automatic deletion execution unit 194.

  Next, the operation of the embodiment of the present invention will be described with reference to the flowchart of FIG.

  When the automatic mail deletion execution unit 194 starts its operation, it first determines from which of the mail reception unit 191 or the mail transmission unit 192 it is activated (step S11, step S21).

  When activated from the mail receiving unit 191 (Yes in step S11), since the received mail BOX 181 is full, an operation of deleting one mail from the received mail BOX is started.

  First, the oldest mail is read from the received mail BOX 181 (step S12).

  Next, it is checked whether or not there is a text in this mail (step S13).

  If there is no body text (Yes in step S13), it is deleted as an unnecessary mail because it is only the subject of the mail, and the process is terminated (step S18).

  If there is a text (No in step S13), it is checked whether the text is one line (step S14).

  If the text is one line (Yes in step S14), since there is almost no content, it is deleted as an unnecessary mail, and the process is terminated (step S18).

  If this determination is not met (No in step S14), it is determined that the target mail is not an unnecessary mail, the process proceeds to the next mail ("Yes" in step S16), and the process is repeated until one is deleted.

  When there is no longer any mail that can be determined to be unnecessary (“None” in step S16), one unprotected mail is deleted from the older one, which is a general process, and the process ends (step S17).

  When activated from the mail transmission unit 192 (Yes in step S21), since the received mail BOX 182 is full, an operation of deleting one mail from the transmitted mail BOX is started.

  First, the oldest mail is read from the transmitted mail BOX 182 (step S22).

  It is checked whether or not there is a text in this mail (step S23).

  If there is no text (No in step S23), it is deleted as an unnecessary mail because it is only the subject of the mail, and the process is terminated (step S28).

  If there is a text (No in step S23), it is checked whether the text is one line (step S24).

  When the text is one line (Yes in step S24), since there is almost no content, it is deleted as an unnecessary mail, and the process is terminated (step S28).

  If this determination is not met (Yes in step S24), it is determined that the target mail is not an unnecessary mail, and the process proceeds to the next mail ("Yes" in step S26), and is repeated until one is deleted.

  When there is no longer any e-mail that can be determined to be unnecessary, one unprotected e-mail is deleted from the oldest, which is a general process, and the process ends (step S27).

  If it is neither the activation from the mail reception unit 191 nor the activation from the mail transmission unit 192 (No in step S21), it can be determined that the activation is based on the schedule from the automatic mail deletion management unit 195. For this reason, an operation for deleting unnecessary mails excluding the deletion exclusion period 230 is started.

  First, the next of the mail checked by this function last time is read from the received mail BOX 181 (step S31).

  This determination is the oldest mail in the first operation because there is no previous operation, and the second and subsequent mails are about the deletion exclusion period 230 before the previous execution date 240.

  Next, it is determined whether or not the read mail is an exclusion period (calculated from the execution date and time of this function and the deletion exclusion period 230) (step S32). As a result of the determination, if the period is an exclusion period (Yes in step S32), the received mail BOX 181 has no mail to be checked, so the process proceeds to the check of the next outgoing mail BOX 182. On the other hand, if it is not the exclusion period (No in step S32), the process proceeds to the deletion determination of the received mail BOX 181.

  Next, it is checked whether or not there is a body text in the read mail (step S33).

  If there is no body text (No in step S33), it is deleted as an unnecessary mail because it is only the subject of the mail, and the process is terminated (step S38).

  If there is a text (No in step S33), it is checked whether the text is one line (step S34).

  If the text is one line (Yes in step S34), it is deleted as an unnecessary mail because there is almost no content, and the process is terminated (step S38).

  If this determination is not met (Yes in step S34), it is determined that the target mail is not an unnecessary mail, and the process moves to the next mail ("Yes" in step S36).

  This process is repeated until there is no next mail (“None” in step S37) or the exclusion period is reached (Yes in step S32).

  This completes the deletion of unnecessary mail from the received mail BOX 181.

  Next, the next of the mail checked with this function last time is read from the transmission mail BOX 181 (step S41).

  This determination is the oldest mail in the first operation because there is no previous operation, and the second and subsequent mails are about the deletion exclusion period 230 before the previous execution date 240.

  Next, it is determined whether or not the read mail is an exclusion period (calculated from the execution date and time of this function and the deletion exclusion period 230) (step S42). As a result of the determination, if the period is an exclusion period (Yes in step S42), there is no mail to be checked in the sent mail BOX 181, so that the next sent mail BOX 182 is checked. On the other hand, if it is not the exclusion period (No in step S42), the process proceeds to deletion determination of the outgoing mail BOX 181.

  Next, it is checked whether or not there is a body text in the read mail (step S43).

  If there is no text (No in step S43), it is deleted as an unnecessary mail because it is only the subject of the mail, and the process is terminated (step S48).

  If there is a text (No in step S43), it is checked whether the text is one line (step S44).

  If the body text is one line (Yes in step S44), since there is almost no content, it is deleted as an unnecessary mail and the process is terminated (step S48).

  If this determination is not met (Yes in step S44), it is determined that the target mail is not an unnecessary mail, and the process proceeds to the next mail ("Yes" in step S46).

  This process is repeated until there is no next mail (“None” in step S47) or until the exclusion period is reached (Yes in step S42).

  As a result, the deletion of unnecessary mail from the transmission mail BOX 182 ends. Finally, the current date and time are written in the previous execution date and time 240 (step S48), and the process ends.

  By the above operation, the mail with only the subject and the mail with only one line of the text are automatically deleted as unnecessary mail.

  The embodiment of the present invention described above has many effects as described below.

  The first effect is that it is possible to prevent the e-mail forgetting the protection setting from disappearing.

  The reason is that when the capacity of the mail box is exceeded, the unnecessary mail is preferentially deleted.

  The second effect is that it is easy to check old mail even if the mobile phone has a smaller screen than a personal computer or the like.

  The reason is that unnecessary mail disappears when automatic deletion is used.

  A third effect is that the user does not have to perform an operation more than necessary.

  The reason is that it is not necessary to set detailed items of special conditions (words, destinations, senders, etc.) as the target mail to be deleted.

  The fourth effect is that the processing time required for the mail confirmation processing is short and the battery consumption is small.

  The reason is that emails checked in the past are not confirmed.

  Although the mail management apparatus according to the embodiment of the present invention can be realized by hardware, the computer reads a program for causing the computer to function as the mail management apparatus from a computer-readable recording medium and executes the program. Can also be realized.

  In addition, the mail management method according to the embodiment of the present invention can be realized by hardware, but the computer can also read and execute a program for causing the computer to execute the method from a computer-readable recording medium. Can be realized.

  Moreover, although the above-described embodiment is a preferred embodiment of the present invention, the scope of the present invention is not limited only to the above-described embodiment, and various modifications are made without departing from the gist of the present invention. Implementation in the form is possible. For example, this time it has been described as an example of mounting on a mobile phone, but it can be mounted by any device as long as it is a device having a mail communication function, such as PHS. In the above-described embodiment, whether or not the body text is one line is used as a criterion (for example, steps S14, S24, S34, and S44), but is not a single line but a predetermined number of characters (for example, 10 characters) or not. May be used as a criterion.
