Description

  The present invention relates to a mail address change notification system and a mail address change notification method for transmitting a change notification mail for notifying a change of a mail address of a user's communication terminal.

  In recent years, so-called junk e-mails have been a problem in which e-mails such as advertisements and solicitations for site browsing are randomly transmitted to an unspecified number of communication terminals that can send and receive e-mails. When a terminal that transmits and receives mail is a mobile communication terminal such as a mobile phone, the receiver generally bears the communication cost required for mail reception processing. Therefore, an unnecessary communication cost is paid each time such junk mail is received. Problems arise. In addition, such a junk e-mail may arrive at an unexpected time zone, such as midnight, for example, and the user's sleep may be disturbed by the ringtone of the e-mail. .

  One measure for preventing such spam mails from being received is to change the mail address of the user's mobile phone to a long mail address. However, when the user changes the e-mail address, it is necessary to notify the friend / acquaintance, etc., who exchanges e-mails that the e-mail address has been changed by e-mail. Such an action is very troublesome for the user, and there is also a problem that the change notification is forgotten.

  Therefore, Patent Document 1 describes an e-mail address change notification system that automatically notifies the user that the e-mail address has been changed by e-mail when the user changes the e-mail address. In the e-mail address change notification system described in Patent Document 1, when an e-mail is sent to the user's old e-mail address, the e-mail sender is notified that the user has made a new e-mail address. The

In this way, by operating the cellular phone 60, the address book information stored in the address backup server 12 and the address book information of the cellular phone 60 are synchronized.

  Further, instead of manually transmitting the address book information to the address backup server 12 as described above, the address book information may be automatically transmitted to the address backup server 12. For example, the address book information may be automatically transmitted to the address backup server 12 at a predetermined time (for example, 10 minutes later) after the editing of the address book on the mobile phone 60 is completed. Further, the address book information may be automatically transmitted to the address backup server 12 based on a predetermined schedule set in advance. The schedule can be set as follows, for example. As shown in FIG. 6A, “address book backup schedule setting” is provided on the menu selection screen of the display screen of the mobile phone 60. When the user selects this “address book backup schedule setting”, a schedule setting screen as shown in FIG. 6B is displayed. From the screen shown in FIG. 6B, the user selects daily, weekly, or monthly, and determines the transmission time and transmission date and time. The cellular phone 60 stores the transmission schedule thus set in the internal memory, and transmits the address book information to the address backup server 12 based on the transmission schedule stored in the internal memory.

The address book backed up by the address backup server 12 can be edited by the personal computer 2 on the Internet. FIG. 7 is a control flow of the address backup server 12 when editing the address book. FIG. 8 is a sequence diagram when editing the address book of the address backup server 12.

Transmit to the backup server 12. When receiving the address data book information acquisition request together with the telephone number and the authentication password from the personal computer 2 (S1), the address backup server 12 determines whether the authentication password is correct (S2). The address backup server 12 stores a data table in which a telephone number and an authentication password are stored in association with each other, and the acquired telephone number and the authentication password are stored in the address backup server 12. It is determined whether or not they match. If they do not match, it is determined that the telephone number or the authentication password is wrong (NO in S2), and a WEB page describing that fact is transmitted to the personal computer 2.

  On the other hand, if they match, it is determined that the input telephone number and the authentication password are correct (YES in S2), and the address book information corresponding to the acquired telephone number is transmitted to the personal computer 2 via the Internet 4. (S3). When the user edits the address book by operating the WEB page on which the address book is displayed, the personal computer 2 transmits the address book editing information to the address backup server 12. When the address backup server 12 receives the address book editing information (YES in S4), the address backup server 12 updates the address book based on the address book editing information (S5). Next, the address backup server 12 transmits the edited address book information to the mobile phone 60 (S6). When the mobile phone 60 receives the address book information, the mobile phone 60 automatically updates the address book in the mobile phone 60 to the received address book information.

Next, the change notification mail transmission setting will be described. FIG. 9 is an explanatory diagram of screen transition of the display 67 of the mobile phone 60 when the change notification mail transmission setting is performed.
The user displays the menu selection screen in FIG. 9A on the display screen of the mobile phone 60. When the user selects “change notification transmission destination setting” on the menu selection screen of FIG. 9A, a change notification transmission destination setting screen as shown in FIG. 9B is displayed. In the change notification destination setting screen, the address book information registered in the address book is displayed below the explanatory text, and the user checks the mail address designated as the change notification destination. When the user selects a change notification transmission destination, a setting completion screen shown in FIG. 9C is displayed on the display 67.
Note that the method for setting the change notification transmission destination is not limited to this. For example, the change notification transmission destination can be specified on the registration / correction screen of the address book. In addition, it can be confirmed from the address book whether or not the change notification destination is designated. Of course, without such a function, when a user's e-mail address is changed, a change notification e-mail may be transmitted to all e-mail addresses registered in the address book.

  When “OK” on the setting completion screen shown in FIG. 9C is selected, the address book information stored in the internal storage device of the mobile phone 60 is updated. Further, the mobile phone number is assigned, and the address book information is transmitted to the backup server 12. The backup server 12 receives the address book information assigned with the mobile phone number from the mobile phone 60, and updates the address book stored in the database 12a.

Next, control when the user changes the mail address will be described.
FIG. 10 is an explanatory diagram of screen transition of the display of the mobile phone when the user changes the mail address. FIG. 11 is a sequence diagram of the mail address change notification system 10 when the user changes the mail address. FIG. 12 is a control flow of the mail address change notification system 10.
The user displays the menu selection screen shown in FIG. 10A on the display 67 of the mobile phone 60. Then, when the user selects “change mail address” on the menu selection screen in FIG. 10A, a mail address change screen as shown in FIG. 9B is displayed on the display 67 of the mobile phone 60. . When the user inputs a new e-mail address in the e-mail address input unit 120 on the e-mail address change screen and selects the OK button, the new e-mail address input from the mobile phone 60 to the e-mail address input unit 120 is transferred to the mail server 11. Sent.

  When the mail server 11 receives the new mail address (S11), the mail server 11 searches the mail server 11 for the same address as the received new mail address, and whether the same mail address as the new mail address has already been registered in the mail server 11. It is checked whether or not (S12). If the same mail address as the new address is already registered in the mail server 11 (YES in S12), the mail server 11 transmits to the mobile phone 60 as a search result that there is the same mail address. When the mobile phone 60 receives the same mail address as a search result, the mobile phone 60 displays the screen shown in FIG. The user selects “Return”, displays the screen of FIG. 10B again, and inputs a different new mail address to the mail address input unit 120.

  On the other hand, when the same mail address as the new address is not registered in the mail server 11 (NO in S12), the mail server 11 transmits to the mobile phone 60 as a search result that there is no same mail address. When the mobile phone 60 receives the search result indicating that there is no identical mail address, the mobile phone 60 changes to a new mail address and displays the screen shown in FIG. When the user selects “notify new address”, the cellular phone 60 transmits the cellular phone number, the new address, and the old address to the mail server 11.

  When the mail server 11 receives the mobile phone number, the new address, and the old address (YES in S13), the mail server 11 deletes the old address and registers a new mail address (S14). In addition, the search unit 11 a of the mail server 11 specifies an address book corresponding to the mobile phone number received from the address table stored in the cache server 13. The e-mail address registered as the change notification transmission destination is searched from the identified address book information (S15), and the change notification transmission destination e-mail address is acquired. Further, the mail creation unit 11b of the mail server 11 creates a change notification mail as shown in FIG. 13 based on the old address and the new address received from the mobile phone 60 (S16). Then, the mail server 11 transmits the change notification mail created by the mail creating unit 11b to the mail address acquired by the search unit 11a (S17).

  As shown in FIG. 13, a link is pasted to the new mail address of the change notification mail. When the change notification mail recipient clicks on this link, the display screen of the recipient mobile phone 60 displays the address. Commands that change to the book registration / modification screen are described. As a result, when the change notification mail recipient clicks on this link, the control unit of the mobile phone 60 receives this command and starts a program for transitioning the display screen of the recipient mobile phone 60 to the address book registration / correction screen. Let

  When the above link is clicked, the mobile phone 60 searches the address book information in which the old address is registered based on the old address described in the change notification mail, and automatically changes it to the new address. May be. Also in this case, as described above, a start command for starting a program for automatically changing to a new address stored in the internal memory of the mobile phone is described in the link part of the change notification mail. When the change notification mail recipient clicks this link, the control unit of the mobile phone receives this command, starts the program stored in the internal memory of the mobile phone, and automatically changes to the new address.

  In the present embodiment, the search unit 11a uses the cache server 13 in which the search database is constructed. However, an address data table that is backed up in storage means in the address backup server 12 may be used. .

  In this embodiment, the user himself / herself sets a new e-mail address. However, an unregistered arbitrary new e-mail address may be acquired from the mail server.

  As described above, according to the e-mail address change notification system of the present embodiment, a change notification e-mail is sent to an e-mail address registered for e-mail transmission / reception in the user's mobile phone address book, thereby changing to a junk e-mail sender. No notification email is sent.

  In addition, the mail address change notification system of this embodiment has a backup server that backs up an address book stored in a mobile phone. Thereby, even if the address book data stored in the mobile phone is damaged, the address book stored in the mobile phone can be restored by downloading the backed-up address book from the backup server.

  In addition, a change notification mail is transmitted using the address book backed up on the backup server. This eliminates the need for the mail server to acquire the address book information stored in the mobile phone by communicating with the mobile phone when transmitting the change notification mail.

  Further, the backup server receives the address book information stored in the mobile phone when the address book information stored in the mobile phone is updated as shown in FIG. 2, or the mobile phone as shown in FIG. The address book information stored in the telephone is periodically received and synchronized with the address book information stored in the mobile phone. As a result, the address book of the mobile phone is updated with the changed recipient's email address, but the backup server can suppress problems such as not being updated with the changed recipient's email address. . As a result, the change notification mail can be reliably transmitted to a predetermined destination.

  Further, the mail server acquires a mail address from the cache server having the search database and transmits a change notification mail. For this reason, the load of the backup server can be reduced as compared with the case where the mail address is acquired from the address book of the database 11a as the storage means of the backup server. Thereby, the fall of the speed of a synchronous process can be suppressed.

  The address book stored in the database 11a of the backup server can be edited with a personal computer or the like. Thereby, the address book can be edited by a communication terminal such as a personal computer having a display screen larger than the display screen of the mobile phone, and the address book of the mobile phone can be easily edited.
