Description

  The present invention relates to a system for notifying other terminals that a mail address of a terminal capable of sending mail has been changed, and a terminal and a server constituting the system, and in particular, changing a mail address without imposing a burden on the user. Can be notified.

  In many cases, the email address of the mobile phone is changed to prevent junk mail. In such a case, it is quite troublesome to communicate the updated email address to the person who wants to be notified of the change.

  Patent Document 1 below proposes a mail address change notification system for eliminating such trouble.

In this system, a user of a mobile phone registers in advance a notification destination e-mail address to be notified of the change of the e-mail address in the mobile phone carrier center. When there is a request for changing the mail address from the user's mobile phone, the mobile phone carrier center changes the mail address and then sends a notification of changing the mail address to the registered notification destination.
JP2003-316695A

  However, in this system, it is necessary for the user to register the mail address change notification destination in advance in the mobile phone carrier center (server), which places a burden on the user. In addition, when the number of users who use this system increases, the burden on the server side that manages a large amount of registered data also increases.

  The present invention was devised in view of such circumstances, and provides a mail address change notification system capable of reducing the burden on the user and the server, and also provides a terminal and a server used in the system. It is aimed.

  The present invention is a system comprising a terminal having a mail function and a server for changing the mail address of the terminal, the terminal holding an address book in which mail addresses of mail destinations are registered, When the terminal requesting the change of the e-mail address is notified of the completion of the e-mail address change process from the server, the e-mail address to which the address change notification e-mail is sent is determined from the e-mail destinations registered in the address book, An address change notification mail including the mail address before the change of the terminal and the mail address after the change of the terminal is transmitted to another terminal with the determined mail address of the mail transmission destination as a destination.

  As described above, in this system, the address change notification mail destination is determined from the address book of the terminal.

  In the system of the present invention, the server retains the mail address before and after the change of the terminal that has performed the mail address change process, and the terminal decides to send an address change notification mail. The mail address of the mail transmission destination is transmitted to the server, and the server generates an address change notification mail and transmits it to another terminal.

  In this system, the change of the mail address of the terminal is notified through the server.

  In the system of the present invention, the terminal holds the mail address before the change and the mail address after the change, and the terminal generates an address change notification mail and transmits it to another terminal.

  In this system, a change in the mail address of a terminal is transmitted to another terminal by the terminal itself.

  Further, in the system of the present invention, when the e-mail address before the change exists in the address book held by another terminal that has received the address change notification e-mail, the e-mail address is updated to the e-mail address after the change. To do.

  In this system, the mail address in the address book is automatically updated.

  In the system of the present invention, the terminal adds at least user-identifiable user information other than the mail address to the address change notification mail, and the other terminals that have received the address change notification mail hold the address When the e-mail address before change does not exist in the book, the e-mail address after change is added to the address book based on the user information included in the address change notification mail.

  In this system, even if the receiving terminal does not own the e-mail address of the terminal that issued the change notification, the changed address is stored in the address book based on the user information such as name and phone number. Can be added.

  In addition, the present invention is a terminal having a mail function, and includes an address book in which a mail address of a mail transmission destination is registered and an address book search unit that searches the address book, and requested to change its own mail address. When the mail address change processing completion is notified from the server, the mail destination to which the address change notification mail is sent is determined from the mail destinations registered in the address book, and the mail address of the mail destination is the address Ask from the book.

  As described above, when the mail address of the terminal is changed, the destination of the address change notification mail notifying the change is determined from the address book of the terminal.

  The terminal of the present invention further includes a data compression unit that compresses the data of the mail address obtained from the address book, and transmits the data compressed by the data compression unit to the server.

  The address change notification mail is created by the server and sent to the destination determined from the address book.

  In addition, the terminal of the present invention further includes a storage unit that holds the mail address before and after the change of the changed mail address, the mail address obtained from the address book as a destination, An address change notification mail including the mail address and the changed mail address is generated and transmitted to another terminal.

  The address change notification mail is created by the terminal and sent to the destination determined from the address book.

  The terminal according to the present invention further includes a mail header adding unit that adds attribute information indicating a change of a mail address to a mail header of the address change notification mail.

  The terminal that has received the address change notification mail can detect this attribute information and distinguish it from the address change notification mail.

  The terminal of the present invention further includes a mail identification unit for identifying whether or not the received mail is an address change notification mail and an address book update unit for updating the address book, and the received mail is an address change notification mail. When the e-mail address before change described in the address change notification e-mail exists in the address book, the e-mail address is updated to the e-mail address after change.

  Therefore, when an address change notification mail of another terminal is received, the mail address in the address book is automatically updated.

  In addition, the terminal of the present invention includes a mail identification unit and an address book update unit as described above, the received mail is identified as the address change notification mail, and the mail address before the change described in the address change notification mail is If it does not exist in the address book, it is determined whether or not user information that can identify at least a user other than an email address is added to the address change notification mail. If it is determined that the user information is added, other The terminal adds the mail address after the change to the address book based on the user information.

  In this terminal, even if the receiving terminal does not own the e-mail address of the terminal that issued the change notification, the changed address is stored in the address book based on user information such as name and phone number. Can be added.

  In the terminal of the present invention, the mail identification unit analyzes the mail header of the received mail, and identifies the mail as the address change notification mail when the mail transmission source is a server.

  Thus, the address change notification mail transmitted from the server can be identified.

  In the terminal of the present invention, the mail identification unit analyzes the mail header of the received mail, and when the mail header includes attribute information indicating the change of the mail address, the mail is identified as the address change notification mail. To do.

  In this way, the address change notification mail transmitted from the terminal can be identified.

  In addition, when the mail identifying unit detects a word indicating an address change from the received mail, the terminal according to the present invention identifies the mail as the address change notification mail.

  It is detected whether it is an address change notification mail by so-called ambiguous detection.

  In addition, the present invention is a server that performs a process for changing a mail address of a terminal, and includes an address change processing unit that performs the change process, a mail address before the change and a mail address after the change of the terminal that has performed the change process The address data decompression unit that decompresses the mail address data for the address change notification mail that is compressed and sent from the terminal, the mail address decompressed by the address data decompression unit as the destination, E-mail header addition part that creates an e-mail header including the e-mail address before change and the e-mail address after change, and attaches the e-mail header created by the e-mail header addition part to the address change notification e-mail to other terminals Send.

  The change of the mail address of the terminal is notified to other terminals through the server.

  In the e-mail address change notification system of the present invention, when notifying the change of the e-mail address of the terminal to other terminals, the user does not need to register the destination in advance in the server, or the server does not have to manage it. The burden on users and servers can be reduced. Also, the terminal and server of the present invention enable this system.

(First embodiment)
FIG. 1 is a schematic diagram of a mail address change notification system according to the first embodiment of the present invention.

  This system includes mobile phones 20, 30, 40, 50 having a mail function, and a server 10 that accepts a change of a mail address. Here, the mobile phone of user A is displayed as mobile phone A20, and the mobile phone of user B is displayed as mobile phone B30.

  User A accesses the server 10 with the mobile phone A20 and changes the mail address of the mobile phone A20. When the update of the e-mail address is completed, the mobile phone A20 causes the user A to select an e-mail address for notification of address change from the e-mail addresses registered in the telephone book (= e-mail address book), and the user A selects The mail address data is mailed to the server 10.

  Here, only the mail addresses of the mobile phone B30 of the user B and the mobile phone D50 of the user D are selected, and the mail address of the mobile phone C40 of the user C is not selected.

  The server 10 mails an address change notification that conveys the new mail address and the old mail address of the mobile phone A20 with the mail addresses of the mobile phone B30 and the mobile phone D50 as destinations.

  When the mobile phone B30 and the mobile phone D50 that have received this mail have the old mail address of the mobile phone A20 in the phone book, they update it with the new mail address.

  FIG. 2 is a block diagram showing the configuration of the mobile phone 20 (the configuration of the mobile phones 30 and 50 is the same).

  The mobile phone 20 includes a communication unit 23, a storage unit 22, a calculation unit 21, a display unit 24, and an input unit 25. The communication unit 23 includes a transmission unit 232 and a reception unit 231. The storage unit 22 includes a user new mail address storage unit 222 that stores the updated mail address, and a transmission destination mail address storage unit 223 serving as a telephone directory.

  The calculation unit 21 includes an address data compression unit 211 that compresses address data, a phone book search unit 212 that searches a phone book, a mail header analysis unit 214 that analyzes a mail header, and a phone book update that updates the phone book. Part 215.

  The telephone directory search unit 212 searches the transmission destination email address storage unit 223 to select the email address of the address change notification destination, and selects the email address to be updated when the address change notification is received. The destination mail address storage unit 223 is searched. The address data compression unit 211 compresses address data to be sent to the server 10. The mail header analysis unit 214 analyzes the header of the received mail, and detects new and old mail addresses described in the mail header when the mail is an address change notification with the server 10 as a transmission source. Further, when the phone book search unit 212 searches for the old mail address from the destination mail address storage unit 223, the phone book update unit 215 updates it with the new mail address.

  The calculation unit 21 implements the address data compression unit 211, the phone book search unit 212, the mail header analysis unit 214, and the phone book update unit 215 by executing a mail address change notification program installed in the mobile phone 20. To do. In addition, the calculation unit 21 displays a screen for confirming the user's intention on the display unit 24 using a GUI specified by the program, and executes a specified process based on an input operation performed from the input unit 25. .

  FIG. 3 is a block diagram showing the configuration of the server 10. The server 10 includes a communication unit 13, a storage unit 12, and a calculation unit 11. The communication unit 13 includes a transmission unit 132 and a reception unit 131. The storage unit 12 includes a user old mail address storage unit 121 that stores an old mail address of each mobile phone whose address has been changed, and a user new mail address storage unit that stores a new mail address of each mobile phone whose address has been changed. 122. The calculation unit 11 includes an address change processing unit 111 that performs a mail address change process, an address data decompression unit 112 that decompresses the compressed address data, and a mail header that adds necessary data to the mail header of the address change notification. And an adding unit 113.

  The address change processing unit 111 performs a mail address change process in response to a request from the mobile phone, stores the mail address before the change in the user old mail address storage unit 121, and stores the mail address after the change in the user new mail address. Stored in the unit 122. The address data decompressing unit 112 decompresses the address data that is compressed and sent from the mobile phone, and restores the mail address. The mail header adding unit 113 adds the new and old mail addresses of the mobile phone to the header of the address change notification mail, and generates a mail header with the restored mail address as a transmission destination.

  The calculation unit 11 implements the address change processing unit 111, the address data decompression unit 112, and the mail header addition unit 113 by executing a mail address change notification program installed in the server 10.

Next, the processing procedure in this system will be described based on the flowcharts of FIGS.
User A inputs a new e-mail address from the mobile phone A and performs an e-mail address changing operation (step 1). The mobile phone A accesses the server and requests to change the mail address (step 2). The server performs an address change process for the mobile phone A, and stores the new and old mail addresses in the user old mail address storage unit 121 and the user new mail address storage unit 122, respectively (step 3). The server notifies the mobile phone A of the completion of the address change process (step 4).

  Receiving this notification, the computing unit 21 of the mobile phone A displays on the display unit 24 that the address change processing has been completed (step 5), and sets “e-mail address for the e-mail address registered in the phone book”. "Do you want to notify me of changes?" Is displayed (step 6). User A performs an operation of selecting one from the input unit 25 (step 7). If “No” is selected (No in Step 8), the process is terminated.

  When “Yes” is selected (Yes in Step 8), the calculation unit 21 checks the check box in front of the name of the address information searched by the telephone directory search unit 212 from the destination mail address storage unit 223 as shown in FIG. Is displayed, and “Please turn off the checkbox of the person who does not want to be notified that the mail address has been changed” is displayed (step 9). User A performs an operation of turning on / off the check box (step 10). If all the check boxes are unchecked (No in step 11), the message “All check boxes are unchecked. Do you want to interrupt the process?” Is displayed (step 15) and waits for the user's selection (step 16) If “Yes” (Yes in Step 17), the process is terminated. If “No” (No in Step 17), the process returns to Step 9.

  If at least one check box is selected (Yes in step 11), “Please write the title / text of the mail” is displayed (step 12), and user A receives the mail title as shown in FIG. And the text (step 13), the message “Notify the person whose check box is turned on that the mail address has been changed. Are you sure?” (Step 14) is displayed.

  When the user A selects “No” (No in Step 18), the process returns to Step 6. If “Yes” is selected (Yes in Step 18), the address data of the user whose check box is checked is read out from the destination mail address storage unit 223 and compressed (Step 19), and the mail shown in FIG. The address data is attached and transmitted to the server (step 20).

  Upon receiving this mail (step 21), the computing unit 11 of the server decompresses the address data (step 22), and, as shown in FIG. 9, the old mail address (Previous-mail-address) of the user A previously stored is stored. ) And a new mail address (Current-mail-address) are added to the mail header, and a mail addressed to the mail addresses of the users B and D whose check boxes are turned on is transmitted (step 23).

  When the mobile phones B and D receive this mail (step 24), the computing unit 21 of the mobile phones B and D analyzes the mail header and identifies whether “From” in the mail header is an address of the server. (Step 25). If it is not the server address (No in step 25), normal mail reception processing is performed (step 34).

  If it is a server address (Yes in step 25), the mail header "Previous-mail-address" is referenced (step 26), and the mail address and destination mail address storage section of this "Previous-mail-address" The mail address recorded in 223 is compared (step 27), and the same mail address is detected (step 28). If the same mail address cannot be detected (No in step 28), the process is terminated. When the same mail address is detected (Yes in step 28), the new mail address of user A is acquired from “Current-mail-address” of the mail header (step 29), and “A's mail address is set to user Do you want to change from -a-previous@docomo.ne.jp to user-a@docomo.ne.jp? "(step 30).

  The process waits for selection of the users B and D (step 31), and when “No” is selected (No in step 32), the process ends. When “Yes” is selected (Yes in step 32), the old mail address of the user A is deleted and a new mail address is registered (step 33).

  Thus, in this system, when the mail address of the mobile phone is changed, the address change notification is automatically sent to the mail address of the other party selected by the user from the mail addresses registered in the mobile phone phone book. Sent.

  Therefore, the user does not need to register the address change notification destination in advance in the server, and the server does not need to manage the address change notification destination designated by each user. Therefore, the burden on the user and the server can be reduced.

  Here, the address data is compressed and sent from the mobile phone A to the server. However, if the data amount of the address data is small, it may not be compressed.

(Second Embodiment)
In the mail address change notification system according to the second embodiment of the present invention, the address change notification is sent as a normal mail from the mobile phone whose address has been changed to the mobile phone of the address change notification destination.

  The schematic diagram of this system is the same as FIG. However, the server 10 only performs the process of changing the address of the mobile phone A20, and the mail notifying the address change transmitted by the mobile phone A20 performs only the normal mail process for transferring to the destination mail address.

  FIG. 10 is a block diagram showing the configuration of the mobile phone 20 of this system (the configuration of the mobile phones 30 and 50 is the same).

  This mobile phone 20 has a user old mail address storage unit 221 that stores a mail address before update in the storage unit 22, and includes a phone book search unit 212, a mail header analysis unit 214, a phone book update in the calculation unit 21. A mail header adding unit 213 for adding necessary data to the mail header is provided together with the unit 215. Other configurations are the same as those of the first embodiment (FIG. 2).

  The mail header adding unit 213 adds an attribute indicating that the mail address has been changed to the header of the mail notifying the address change.

  The computing unit 21 implements a phone book search unit 212, a mail header analysis unit 214, a phone book update unit 215, and a mail header addition unit 213 by executing a mail address change notification program installed in the mobile phone 20. .

  Next, the processing procedure in this system will be described based on the flowcharts of FIGS. 11, 12, and 13.

  User A inputs a new e-mail address from the mobile phone A and changes the e-mail address (step 50). The mobile phone A accesses the server and requests to change the mail address (step 51). The server performs an address change process for the mobile phone A (step 52), and notifies the mobile phone A of the completion of the address change process (step 53).

  Receiving this notification, the computing unit 21 of the mobile phone A stores the old mail address in the user old mail address storage unit 221, stores the new mail address in the user new mail address storage unit 222 (step 54), and changes the address. The completion of processing is displayed on the display unit 24 (step 55).

  The subsequent processing in steps 56 to 67 is the same as that in steps 6 to 17 in the first embodiment (FIG. 4), and the other party who notifies the change of the mail address from the addresses registered in the telephone directory. Is specified based on the intention of the user A.

  The computing unit 21 of the mobile phone A confirms to the user A about notifying the other party specified by the check box of the change of the mail address (step 68), and then mails the address data of the user whose check box is turned on. Are added to the mail address, an attribute indicating that the mail address has been changed is added to the mail header, and the old mail address stored in the user old mail address storage unit 221 and the user new mail address storage unit 222 are added. The new mail address saved in is added to the header.

  FIG. 14 shows the mail header subjected to the processing in step 69. In the destination, the mail addresses of the mobile phones B and D informing the address change are described, and “Mail-address-changed: yes” is described as an attribute indicating that the mail address has been changed. An address (Previous-mail-address) and a new mail address (Current-mail-address) are described.

  The mobile phone A transmits this mail (step 70). The server performs normal mail processing (step 71) (step 72).

  Upon receiving this mail (step 73), the computing units 21 of the mobile phones B and D analyze the mail header and identify whether “Mail-address-changed” in the mail header is “Yes” (step 74). ). When it is not “Yes” (No in step 74), a normal mail reception process is performed (step 83).

  When “Mail-address-changed” is “Yes” (Yes in Step 74), the same processing as Steps 26 to 33 in the first embodiment (FIG. 4) is performed as the processing of subsequent Steps 75 to 82. . That is, referring to “Previous-mail-address” in the mail header (step 26), when the same mail address as that of “Previous-mail-address” is recorded in the destination mail address storage unit 223. After confirming the intentions of the users B and D, the old mail address of the user A is deleted and a new mail address is registered.

  Thus, in this system, when the e-mail address of a mobile phone is changed, the e-mail notifying the address change directly to the other party selected by the user from the e-mail addresses registered in the mobile phone's phone book Will be sent.

  Therefore, the user does not need to register the address change notification destination in advance in the server, and the server does not need to perform special processing. Therefore, the burden on the user and the server is reduced.

  In the first and second embodiments, the title / text of the mail informing the user of the address change is written (steps 13 and 63). However, in order to save the user's trouble, a standard one is used. You may do it.

  In the first and second embodiments, when the mail address is changed, a check box for specifying the address change notification destination is turned on / off (steps 10 and 60). This operation may be performed in advance before the change, and when the mail address is changed, the operation result may be displayed and confirmed.

  In addition, since the mobile terminals B and D that have received the mail have the server described in the mail header transmission source in the first embodiment, the mail address in the mail header in the second embodiment. Is identified as an address change notification because it has an attribute indicating that it has been changed, but using so-called fuzzy search, words / words (such as “address change”, “change notification”, etc.) ) May be identified as a change notification.

(Other embodiments)
In the first and second embodiments described above, the receiving terminal (mobile phone BD) that receives the address change notification refers to the old mail address added to the mail header of the received mail, and the mail address Is recognized (step 28 in FIG. 6). However, under this configuration, if the recipient's terminal does not hold the old email address of the other party whose email address has been changed (for example, only the name and phone number are held), the other party can be detected. Even if a notification of a new mail address is received, the user cannot easily take the new address into the terminal as in steps 29 to 33 in FIG.

  Here, the first and second embodiments can be modified so that the receiving side can easily capture a new mail address even under the above-described circumstances.

  FIG. 15 is a block diagram showing a configuration of the mobile phone 20 in a modification of the first embodiment. In addition to the configuration in FIG. 2, a user information storage unit 224 is added to the storage unit 22. The user information storage unit 224 is a part for storing user information other than the mail address, and stores information for identifying a user other than the mail address, such as a user name and a telephone number.

  FIG. 16 is a block diagram showing a configuration of the server 10 in the modification of the first embodiment. In addition to the configuration in FIG. 3, user information having the same function as the user information storage unit 224 in the mobile phone 20 is shown. A memory 123 is added.

  The processing procedure in this modification will be described based on the flowcharts of FIGS. It is assumed that the mobile phone A performs a procedure that is exactly the same as the processing procedure of the flowchart of FIG. However, in Step 6, the part “for the mail address registered in the telephone book” becomes “for the person registered in the telephone book”.

  As shown in FIG. 17, unlike the case of FIG. 5 of the first embodiment, in this modification, in step 20, in addition to the address data, own user information (for example, name and name) stored in the user information storage unit 224 is displayed. A phone number is also attached to the email and sent to the server. Therefore, unlike FIG. 8 which is the mail according to the first embodiment, the mail according to the present modification has “User-name” and “Phone-number” added thereto as shown in FIG.

  Upon receiving this mail (step 21), the computing unit 11 of the server decompresses the address data (step 22), and the old mail address (Previous-mail-address) of the user A previously stored as shown in FIG. In addition to the new mail address (Current-mail-address), the user information held in the user information storage unit 123 is added to the mail header as shown in FIG. 20, and the users B and D whose check boxes are on are added. An email addressed to the email address is transmitted (step 23).

  Next, B and D processing of the mobile phone on the receiving side will be described with reference to FIG. The processing in steps 24 to 27 is the same as that in FIG. However, if “From” in the mail header is not the server address in step 25 (No in step 25), the process is terminated.

  If it is a server address (Yes in step 25), the mail header "Previous-mail-address" is referenced (step 26), and the mail address and destination mail address storage section of this "Previous-mail-address" The mail address recorded in 223 is compared (step 27), and the same mail address is detected (step 28). If the same mail address can be detected (Yes in step 28), the migration process is the same as in FIG.

On the other hand, when the same e-mail address cannot be detected (No in step 28), this example further refers to “User-name” and “Phone-number” in the e-mail header shown in FIG. 20 (step 35). “User-name” and “Phone-number” are compared with information registered in the address book (user information storage unit 224 of the storage unit 22) (step 36). And
If both “User-name” and “Phone-number” match (Yes in step 37), it becomes clear that the name and phone number of user A are registered (the email address is not registered). In step 29 and subsequent steps, the address of user A is registered. If both “User-name” and “Phone-number” do not match (No in step 37), the process ends.

  As described above, in this example, when the mail address of the mobile phone is changed, the address change notification is automatically sent to the mail address of the other party selected by the user from the mail addresses registered in the mobile phone phone book. At this time, other specific information (name, telephone number, etc.) on the transmitting side is also sent.

  Therefore, even if the sender's terminal does not keep the sender's old email address whose email address has been changed (for example, only the name and phone number), the sender is detected and specified. The new address can be easily taken into the terminal.

  Although the above description relates to a modification of the first embodiment, the second embodiment can be similarly modified. FIG. 21 is a block diagram showing a configuration of the mobile phone 20 in a modification of the second embodiment. In addition to the configuration of FIG. 10, a user information storage unit 224 is added to the storage unit 22.

  The processing procedure in this modification is represented as shown in the flowchart of FIG. Note that the processing procedure in the mobile phone A is the same as that in the first embodiment. Unlike the mail of FIG. 14 which is the mail of the second embodiment, the mail in this modified example is one in which “User-name” and “Phone-number” are added as shown in FIG.

  The process of FIG. 22 is obtained by adding steps 84 to 86 corresponding to steps 35 to 37 of the process of FIG. 18 to the process of FIG. Also in this modification, the same effect as the modification mentioned above is acquired.

  In the above-described embodiment, after the address data is compressed by the address data compression unit (for example, step 19 in FIG. 5), the compressed data is transmitted, but the data is further encrypted and transmitted. In this way, security can be improved.

  In the above-described embodiment, the configuration has been described in which the side (mobile phone B, D) that receives the new mail address asks the user for confirmation when deleting the old mail address (for example, step 30 in FIG. 4). However, this configuration is not essential, and the old e-mail address may be deleted automatically by the receiving terminal.
