Description

  The present invention relates to a mail transmission / reception function in a mobile phone, and in particular, a mail that is divided and transmitted / received by character number restriction or a mail that is related to each other is associated as a mail group, and one mail of the associated mail group This is related to a mobile phone having a group processing function of transmitted / received mail that collectively processes a plurality of mails belonging to the same mail group when a desired mail operation is performed.

  With the development of information processing technology and communication technology in recent years, various portable information communication terminal devices (hereinafter referred to as mobile terminal devices) have become widespread. Such a mobile terminal device is connected to an information distribution server or a desired website that provides various services via a network such as the Internet when the user is out, or receives the service, or acquires information, It is possible to obtain information necessary for business by connecting to the company's network.

  Recently, the hardware and software functions of mobile phones have been enhanced, and the functions of conventional mobile terminal devices have been enhanced, and there is a remarkable increase in the penetration rate of mobile phones. The number of operators providing data communication services using mobile phones is increasing, and various services such as banking, Internet sales, navigation, vending machines, payment for transportation and convenience stores, etc. using mobile phones. It has become possible to receive. In particular, mobile phones can be equipped with various options and applications, and the types of services that can be used are increasing.

  In addition, a mobile phone called the third generation is equipped with a GPS receiver, can measure the current position (latitude / longitude) where the mobile phone itself is located, and a navigation system using the mobile phone as a terminal device is also available. It has been put into practical use. Various systems that can be used for confirming the position of elderly people, children, etc., and confirming the position at the time of reporting in cases such as crimes and fires, accidents using such a positioning system have been studied.

  In addition, users install various applications developed for mobile phones such as browsers, applications, and game software provided by service providers on their own mobile phones and add desired services and functions. Can be customized to do.

  The main function of a mobile phone is a call function, but many users use electronic mail (hereinafter simply referred to as mail) using the Internet as means for changing to a call. This is because the data communication charge using the Internet is lower than the call charge, and the flat rate charge has been established. In the case of e-mail, there is no need for a line connection between the sender and the receiver. This is because it is possible to perform mail transmission / reception operations when both parties are arbitrarily convenient.

In the transmission / reception of e-mails in mobile phones, most communication carriers have restrictions on the amount of data that can be transmitted / received at once, that is, the amount of communication packets. Generally, the amount of communication packets that can be communicated at one time is set to about 500 characters in text data. Due to such restrictions, when an e-mail body with a data amount exceeding 500 characters is created, the excess data is usually truncated and only halfway data can be transmitted and received.

Therefore, if you do not perform cumbersome operations such as sending an email after checking whether the amount of email data created by the user exceeds the restrictions, the email text sent to the other party will be truncated and the entire text will be An undelivered case occurs. When pasting an image or using pictograms in an email, there is a problem that the sender does not know that the text has been truncated because it does not know whether the amount of text exceeds the limit .

  In order to solve such a problem, there has also been proposed a communication apparatus having a function of automatically dividing and transmitting mail when the mail exceeds a prescribed data amount. For example, in the following Patent Document 1 (Japanese Patent Laid-Open No. 2002-157192), a warning screen is displayed when the number of characters of a mail created by the user exceeds the limit, and a selection screen for selecting whether or not to transmit as a divided mail Is displayed, the user knows that the number of restricted characters has been exceeded, and can specify whether or not to send a divided mail.

Also, in the following Patent Document 2 (Japanese Patent Laid-Open No. 2002-247102), when a divided mail transmitted from a sender is delivered to a destination, a mail that performs processing to add the presence / absence of a divided mail, the number of remaining characters, etc. to the header A mail transmission method provided with a processing server is disclosed. According to such a mail transmission method, the recipient of the divided mail can refer to the header to know the presence / absence of the divided mail and the number of remaining characters and select whether or not to receive the remaining divided mail. It becomes like this.

The same applies to mail transfer processing, in which all mail registered in a group for a specified transfer destination is transferred in a batch. Note that the collective processing here may include a mode in which the mail processing control unit 30 automatically and sequentially processes all mails without any user operation.

  Also, if a split ID is set when a mail is received and a group registration ID is automatically set, the same split ID is added if one of the split mails is selected and mail processing is specified. Multiple emails can be processed at once. If the mail processing control unit 30 is configured to collectively process mail having the same division ID by referring to the division ID in addition to the group registration ID when mail processing is performed, the group registration ID is assigned to the division mail. No need to set.

  Next, the group processing procedure of the mobile phone 10 described above will be described based on the flowcharts shown in FIGS. FIG. 5 is a flowchart showing a processing procedure for performing group registration by associating a plurality of related transmission / reception emails, and FIG. 6 is a flowchart showing a processing procedure for batch processing of emails. FIG. 7 is a flowchart showing a procedure for displaying a group-registered divided mail, and FIG. 8 is a flowchart showing a procedure for mail transmission processing.

  First, a mail group registration procedure will be described with reference to FIG. In the process of step S11, the mail processing control unit 30 determines whether or not a divided mail has been received. If it is not the reception of the divided mail, the process proceeds to step S14, and if it is the reception of the divided mail, the division ID is added to the divided mail in the process of step S12. The received mail is stored (saved) in the received mail storage unit 25 in the process of step S13.

  In the case where the user selects whether or not to save the received mail, the procedure of steps S12 and S13 may be performed when the mail saving process is selected.

  Next, in the process of step S <b> 14, the mail processing control unit 30 displays a message for inquiring whether or not to group the received mail on the display unit 23. If the user does not select group registration, the process returns to the mail reception determination waiting state in step S11.

  When group registration is selected by the user, in the process of step S15, the received mail list and the transmitted mail list shown in FIGS. 3 and 4 are displayed on the display unit 23, and when the user selects mail to be group registered, step The process proceeds to S16. When the user inputs the group registration ID in the process of step S16, the group registration ID input to each mail is added, and the mail is associated. When the mail processing control unit 30 is configured to automatically assign and add a group registration ID, the process of step S16 can be omitted, and the user's input can be saved.

  In the process of step S17, a message for confirming to the user whether there is another mail for group registration is displayed. If the user selects another mail with group registration, the process returns to step S15 and the above process is repeated. If no mail for group registration is selected, the process returns to the mail reception determination waiting state in step S11.

  Note that the processes in steps S14 to S18 can also be executed by the user selecting a mail group registration process other than when receiving a mail.

  Batch processing of a plurality of related mails registered as a group is performed according to the procedure shown in FIG. In the process of step S21, the mail processing control unit 30 selects one of the mails stored in the received mail storage unit 25 or the transmitted mail storage unit 26 and performs mail processing operations such as mail deletion processing and mail transfer processing. To determine whether or not

  If the mail processing operation has not been performed, the process ends. If the mail processing operation has been performed, the process proceeds to step S22, and the mail processing control unit 30 sends the selected mail to the received mail storage unit 25 or the transmitted mail. Read from the storage unit 26.

  Next, the mail processing control unit 30 refers to the received mail list and the transmitted mail list in FIGS. 3 and 4 in the process of step S23, and the same group registration ID as the group registration ID added to the mail selected by the user in the process of step S21. It is determined whether or not there is a mail with a registration ID added. If there is no mail with the same group registration ID, the process proceeds to step S25, and the mail process read in the process of step S22 (the process specified in step S21) is executed. For example, if the designated process is a mail deletion process, a mail deletion process is performed, and if the designated process is a mail transfer process, a process of forwarding the mail to a designated destination is performed.

  When it is determined that there is a mail with the same group registration ID added in the process of step S23, the mail processing control unit 30 reads the mails from the received mail storage unit 25 and the transmitted mail storage unit 26 in the process of step S24. All of the read mails are collectively processed in the process of step S25.

  Further, when the user performs a split mail display processing operation, the related split mails are combined and displayed on the display unit 23 according to the processing procedure of FIG. That is, when the user selects an arbitrary mail in the process of step S31 and performs a display process operation, the mail display control unit 28 performs the received mail list and the transmitted mail list of FIGS. 3 and 4 in the process of step S32. In step S31, it is determined whether or not there is a mail with the same division ID as the division ID added to the mail selected by the user in the process of step S31.

  If there is no mail with the same division ID, the process proceeds to step S35, and the process proceeds to step S35. The selected mail is read from the received mail storage unit 25 or the transmitted mail storage unit 26 and displayed in the process of step S36. The processing is expanded in the memory 29, displayed on the display unit 23, and the processing is terminated.

  If there is a mail to which the same division ID is added, the mail display control unit 28 reads all the mails to which the same division ID is added from the received mail storage unit 25 or the transmission mail storage unit 26 in the process of step S33, and step S34. In the process, the mails are combined with the display memory 29 and expanded, and displayed on the display unit 23 in the process of step S36, and the process ends.

  Next, the mail transmission procedure will be described. As shown in the flowchart of FIG. 8, when the user performs a mail transmission operation in the process of step S41, the mail processing control unit 30 calculates the data amount of the mail (transmitted mail) created by the user in the process of step S42. In the process of step S43, it is determined whether the data amount of the outgoing mail is within the prescribed data amount. If the calculated data amount exceeds the prescribed data amount, the mail processing control unit 30 divides the transmitted mail in the process of step S44, and transmits the divided mail to the designated destination in the process of step S45. If the calculated data amount is within the range of the prescribed data amount, the mail is directly transmitted to the designated destination in step S45.

  The mail processing control unit 30 determines whether or not to save the transmitted mail in the process of step S46. If the user has not designated saving of the outgoing mail, the process is terminated. If the saving has been designated, the outgoing mail is saved in the outgoing mail storage unit 26 in step S47. Then, in the process of step S48, it is determined whether or not the outgoing mail is a divided mail.

  If the outgoing mail is not a split mail, the mail processing control unit 30 adds the data related to the outgoing mail to the outgoing mail list shown in FIG. When the outgoing mail is a split mail, the mail processing control unit 30 adds and stores a split ID for each outgoing mail divided when adding data related to the outgoing mail to the outgoing mail list shown in FIG. Exit.

  As described above, according to the present invention, it is possible to perform mail processing on the received or transmitted divided mail and related mail registered by the user as a group. Further, when displaying the divided mail, the divided mails can be combined and displayed.
