Description

  The present invention relates to a message processing system and a message processing method for processing a message transmitted to old destination information of one communication terminal.

2. Description of the Related Art Conventionally, in a communication system such as a telephone or electronic mail, a technique for processing a message transmitted to old destination information of a communication terminal whose destination information such as a telephone number or a mail address has been changed is known. For example, Patent Document 1 below discloses an e-mail system that transfers an e-mail addressed to an old address of a user who has registered for address change to the new address of the user. This electronic mail system stores the old address and the new address of the address changer in association with each other based on the registration of the address changer. When the e-mail system receives a mail addressed to the old address, it extracts a new address corresponding to the old address and transfers the received mail to the new address.
JP 2001-111601 A

  However, since the e-mail system of the above-mentioned patent document 1 executes mail transfer unconditionally once the address changer's new address is registered, the address changer's undesired transfer is performed. For example, the address changer receives mail from a partner who has little chance of communicating in the future or who does not want to be contacted.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a message processing system and a message processing method capable of preventing transmission of a message that the address changer does not want to receive. .

  The message processing system of the present invention includes a destination storage means for storing old destination information before change of one communication terminal and new destination information after change, and a message addressed to the old destination information from another communication terminal. Receiving means for receiving; registration information storage means for storing registration information indicating the possibility of future communication between one communication terminal and another communication terminal; registration information stored in the registration information storage means; A determination unit that determines whether or not to execute a communication process that enables future communication between one communication terminal and another communication terminal based on the message received by the reception unit; And a processing unit that executes the communication process using the new destination information stored in the destination storage unit when it is determined to execute the communication process.

  The message processing method of the present invention is a message processing method in which a message processing system processes a message, and the message processing system uses the old destination information before the change of one communication terminal and the new destination information after the change. A destination storing step for storing in association, a receiving step for the message processing system to receive a message addressed to the old destination information from another communication terminal, and a message processing system between the one communication terminal and another communication terminal. A registration information storage step for storing registration information indicating the possibility of future communication, and a message processing system based on the registration information stored in the registration information storage step and the message received in the reception step. Whether or not to execute communication processing that enables future communication between the other communication terminal and another communication terminal And a processing step of executing the communication process using the new destination information stored in the destination storage step when it is determined that the message processing system executes the communication process in the determination step. Features.

  According to such a message processing system and message processing method, when a message addressed to the old destination information of the one communication terminal whose destination information has been changed is received, the one communication terminal that is the destination and the other source Whether or not to execute communication processing that enables future communication between one communication terminal and another communication terminal based on registration information indicating the possibility of future communication with the other communication terminal Determined. Only when it is determined to execute the communication process, the communication process is executed using the new destination information. In this way, the possibility of future communication between the two terminals is taken into consideration, and it is determined whether or not communication between the two terminals is enabled, thereby preventing transmission of messages that the destination changer does not want to receive. It becomes possible to do.

  In the message processing system of the present invention, the registration information is preferably a history of communication between one communication terminal and another communication terminal.

  In this case, it is determined whether or not to execute communication processing based on the history of communication between one communication terminal and another communication terminal. If you look at the history of communication between the communication terminal that sent the message and the communication terminal that is the destination of the message, the possibility of future communication between those terminals and the closeness of the users who communicate with each other It is possible to guess. Therefore, by determining whether communication processing is necessary based on the past communication status, it is possible to prevent transmission of a message that the destination changer does not want to receive.

  In the message processing system of the present invention, the registration information is the phone book information of one communication terminal including the destination information of the communication partner terminal, and the determination means is another communication terminal in the phone book information of the one communication terminal. It is preferable to determine whether or not to execute communication processing based on the presence or absence of registration.

  In this case, the necessity of communication processing is determined based on the presence / absence of registration of another communication terminal in the phone book information of one communication terminal that is the transmission destination. It can be said that the telephone directory information reflects the possibility and closeness of future communication with the communication partner. Therefore, by determining the necessity of message processing in consideration of the phone book information, the possibility and familiarity of future communication can be estimated more accurately, and the communication processing is executed more in accordance with the intention of the destination changer. It becomes possible.

  In the message processing system of the present invention, it is preferable that the communication process is a process of switching the destination of the message received by the receiving unit to the new destination information.

  In this case, based on the registration information, it is determined whether or not to switch the message destination to the new destination information. Only when it is determined to switch the destination, the message destination is switched to the new destination information. In this way, a message that the destination changer does not want to transfer by determining whether or not destination switching (transfer) is necessary in consideration of the possibility of future communication between one communication terminal and another communication terminal. It becomes possible not to transfer.

  In the message processing system of the present invention, the communication process is preferably a process of notifying other communication terminals of the new destination information.

  In this case, based on the registration information, it is determined whether to notify the new destination information of the one communication terminal to the other communication terminal that has transmitted the message addressed to the old destination information of the one communication terminal. The notification process is performed only when it is determined to notify. Thereby, it is possible to prevent the new destination information from being notified to an unspecified number of people, and to notify the new destination information only to a communication partner or an intimate partner with a high possibility of future communication. That is, the security of the new destination information can be improved.

  According to such a message processing system and a message processing method, based on registration information indicating the possibility of future communication between one communication terminal as a transmission destination and another communication terminal as a transmission source. Because it is determined whether or not to execute communication processing that enables future communication between the communication terminal and another communication terminal, it is possible to prevent transmission of a message that the destination changer does not want to receive become.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

  First, the mail transfer system (mail processing system) 10 according to the embodiment will be described with reference to FIGS. FIG. 1 is a diagram illustrating an overall configuration of a communication system including a mail transfer system 10 and a portable terminal 30. FIG. 2 is a diagram illustrating a functional configuration of the mail transfer system 10. FIG. 3 is a diagram illustrating an example of address data stored in the address storage unit 11 illustrated in FIG. FIG. 4 is a diagram illustrating an example of user information stored in the user information storage unit 12 illustrated in FIG. FIG. 5 is a diagram illustrating an example of processing rules stored in the rule storage unit 14 illustrated in FIG.

  The mail transfer system 10 and each portable terminal 30 illustrated in FIG. 1 can perform data communication with each other via the network N. Although two portable terminals 30 are shown in FIG. 1, the number of portable terminals 30 is not limited.

  The mail transfer system 10 transmits and receives electronic mail (hereinafter simply referred to as “mail”) based on the SMTP (Simple Mail Transfer Protocol) protocol, the POP (Post Office Protocol) protocol, or the IMAP (Internet Message Access Protocol) protocol. It is a computer system. The specific hardware configuration of the mail transfer system 10 is not limited. For example, the mail transfer system 10 may be configured with a single server, or may be configured with a distributed system including a plurality of servers.

  Specifically, the mail transfer system 10 receives a mail (message) transmitted from the mobile terminal 30 and transmits the mail (message) to another mobile terminal 30, or the other mobile phone constructed in a storage area such as a hard disk. Or storing it in the mailbox of the terminal 30. The mail transfer system 10 can also send and receive mail to and from other communication devices (not shown) (for example, other mail servers and relay devices). Further, the mail transfer system 10 can transfer a mail transmitted to the old address of the mobile terminal 30 whose mail address has been changed to the new address of the mobile terminal 30. Further, the mail transfer system 10 can store a backup of the phone book information registered in each mobile terminal 30.

  The mobile terminal 30 is a communication terminal having a call function and a mail transmission / reception function, and specifically, a mobile phone or a portable information terminal (PDA: Personal Digital Assistant). The portable terminal 30 includes a database (memory) for storing telephone numbers and mail addresses as destination information of other portable terminals 30 as telephone book information. The portable terminal 30 can read the phone book information and set a call destination or mail transmission destination, or update the phone book information. Further, the mobile terminal 30 can send and receive phone book information to and from the mail transfer system 10. Thereby, the portable terminal 30 can store a backup of the phone book information in the mail transfer system 10 and restore the phone book information in the own device using the backup as necessary.

  The network N is configured by a mobile communication network, the Internet, a LAN (Local Area Network), and the like. The network N may be a network dedicated to one telecommunications carrier or a set of networks of a plurality of telecommunications carriers. The specific configuration of the network N is not limited.

  Next, the functional configuration of the mail transfer system 10 will be described with reference to FIG. The mail transfer system 10 includes an address storage unit (destination storage unit) 11, a user information storage unit (registered information storage unit) 12, a mail reception unit (reception unit) 13, a rule storage unit 14, and a transfer determination unit (determination unit) 15. , A mail transfer unit (processing unit) 16, a notification determination unit (determination unit) 17, and a notification unit (processing unit) 18.

  The address storage unit 11 is means for storing a mail address of the mobile terminal 30 (user). Specifically, the address storage unit 11 stores address data in which a user ID for identifying a user of the mobile terminal, a current address (new address), and an old address are associated with each other. The information used for identifying the user of the mobile terminal is not limited to the user ID, and the user may be identified by a telephone number, a terminal ID of the mobile terminal, or the like. An example of stored address data is shown in FIG. In the example of FIG. 3, for the users A and F, since the mail address has been changed, both the new address and the old address are stored. On the other hand, for the users B to E, since the mail address has not been changed, only the current address is stored.

  The user information storage unit 12 is means for storing telephone directory information and communication history for each portable terminal 30 (for each user). As shown in FIG. 4, the user information storage unit 12 stores one or more pieces of user information identified by a user ID and including telephone directory information and communication history.

  The phone book information includes partner information in which a user ID (partner ID) for identifying a communication partner terminal is associated with a mail address (partner address) that is destination information of the communication partner. Since the user of the mobile terminal 30 generally communicates with a communication partner registered in the phone book information in general, the phone book information is a kind of registration information indicating the possibility of future communication between the two terminals. It is. The user information storage unit 12 receives telephone book information registered and transmitted by each portable terminal 30 for purposes such as backup. Subsequently, the user information storage unit 12 extracts the user ID from the received phone book information, and updates or newly creates the phone book information of the corresponding user ID. Note that the update or creation of the phone book information may be executed by other components not shown.

  The communication history includes the date and time when the mail transfer system 10 relayed the mail, the user ID (communication partner ID) indicating the communication partner (destination or transmission source) of the mail, and the mail address (communication partner address) of the mail communication partner. Is a set of communication records associated with. Since the trend of the communication status (communication time, communication frequency, etc.) between the two terminals can be acquired by looking at the communication history, the communication history is a type of registration information indicating the possibility of future communication between the two terminals. The user information storage unit 12 acquires a mail when the mail receiving unit 13 described later receives the mail, and extracts a destination address and a transmission source address from the mail. Further, the user information storage unit 12 acquires the date and time when the mail is acquired or the mail reception date and time as the relay date and time. Subsequently, the user information storage unit 12 reads the user ID corresponding to each extracted address from the address storage unit, and adds a communication record to the user information (communication history) of the corresponding user ID.

  For example, when a mail having a source address “aaa@xxx.ne.jp” and a destination address “bb2@xxx.ne.jp” is received, the user information storage unit 12 obtains these two addresses from the mail. get. Subsequently, the user information storage unit 12 reads the user IDs “user A” and “user B” corresponding to each address from the address storage unit 11. Subsequently, the user information storage unit 12 adds a communication record including the acquired relay date and time, the user ID “user B” and the communication partner address “bb2@xxx.ne.jp” to the communication history of the user A, A communication record including the date and time, the user ID “user A” and the communication partner address “aaa@xxx.ne.jp” is added to the communication history of the user B.

  FIG. 4 shows user information of users A and B. Both the user information of the users A and B include both the phone book information and the communication history. Among the user information stored by the user information storage unit 12, either of the phone book information or the communication history is included. Some may include only one of them. For example, the user information of the mobile terminal 30 that has backed up the phone book information using the mail transfer system 10 but has not yet exchanged mail with another communication terminal includes only the phone book information. become. In addition, the user information of the mobile terminal 30 that has sent and received mail with other communication terminals but has not backed up the phone book information includes only the communication history.

  Note that the update / creation of the phone book information and the creation of the communication record may be performed by other components not shown.

  The mail receiving unit 13 is means for receiving a mail (message) from the portable terminal 30 and outputting the mail to the transfer determining unit 15 and the notification determining unit 17. In the following description, the mobile terminal 30 that transmitted the mail is particularly referred to as a transmission source terminal (another terminal terminal) 30a, and the mobile terminal 30 that is a mail transmission destination is particularly referred to as a transmission destination terminal (one communication terminal) 30b.

  The rule storage unit 14 is a means for storing rules for processing received mail. Specifically, the rule storage unit 14 transmits a rule (transfer rule) used when determining whether or not to forward the received mail to the new address of the transmission destination terminal 30b, and a change notification to be described later, the transmission source terminal 30a. The rule (notification rule) used when determining whether to transmit to is stored.

  As shown in FIG. 5, the processing rules stored in the rule storage unit 14 include three types of attributes (phone book mutual registration, latest communication timing, and communication count) indicating the relationship between the transmission source terminal 30a and the transmission destination terminal 30b. And a flag indicating whether or not to forward the received mail and notify the transmission source.

  The phone book mutual registration is an attribute indicating whether or not the other party's mail address is registered between the transmission source terminal 30a and the transmission destination terminal 30b. This attribute is determined based on the phone book information stored in the user information storage unit 12. If the phone book information of the transmission source terminal 30a includes the mail address of the transmission destination terminal 30b and the phone book information of the transmission destination terminal 30b includes the mail address of the transmission source terminal 30a, the phone book mutual registration is performed. It is determined to be “present”, and “other” is determined otherwise. Therefore, it is determined that the phone book information of the transmission source terminal 30a or the transmission destination terminal 30b does not exist in the user information storage unit 12 as “none”.

  The latest communication time is an attribute indicating whether or not mail transmission / reception has occurred in a predetermined period between the transmission source terminal 30a and the transmission destination terminal 30b. In the example of FIG. 5, whether or not mail transmission / reception has been performed in the last month is a criterion for determination. The communication count is an attribute indicating the number of times that mail transmission / reception has been performed between the transmission source terminal 30a and the transmission destination terminal 30b in a predetermined period. In the example of FIG. 5, the number of times of mail transmission / reception performed in the latest half year is used as a criterion. Therefore, it can be said that the latest communication time and the number of communication are attributes indicating the history of communication between the transmission source terminal 30a and the transmission destination terminal 30b. It should be noted that the latest communication time and the communication frequency setting method (setting of period, frequency threshold, etc.) may be arbitrarily set.

  In FIG. 5, the flag indicating the received mail processing is indicated by a symbol “◯” or blank. The symbol “◯” indicates that the corresponding process is executed, and the blank indicates that the corresponding process is not performed. According to the transfer rule of FIG. 5, if the phone book mutual registration is made, the transfer is performed regardless of the communication history. If the phone book mutual registration is not made, the first predetermined period (the latest communication time) The transfer is performed only when communication is performed within the period defined by According to the notification rule of FIG. 5, if the phone book mutual registration is made, the communication has been performed within the first predetermined period or the number of communication in the second predetermined period (period defining the number of communication) is predetermined. Notification is made on condition that the threshold is equal to or greater than the threshold value. Even if the phone book mutual registration is not performed, notification is executed if communication is performed within the first predetermined period.

  For example, when phonebooks are registered with each other and communication has been carried out within the last month, and the number of communications in the last six months is five times, mail forwarding and notification to the sender are executed. Is done. On the other hand, if the phone book is not mutually registered and communication has not been performed within the last month, mail transfer and notification to the sender will be performed no matter how many times the communication has been performed in the last six months. Absent.

  Note that how the flag is set is arbitrary. For example, in order to further increase the security of the new address, the notification flag may be set to “◯” only when the phonebook mutual registration is “present”.

  Returning to FIG. 2, the transfer determination unit 15 sets the destination of the mail addressed to the old address received by the mail reception unit 13 to the new address based on the phone book information and the communication history stored in the user information storage unit 12. It is means for determining whether or not to switch. For example, the transfer determination unit 15 determines whether or not the transmission destination terminal 30b is registered in the telephone directory information of the transmission source terminal 30a, whether or not the transmission source terminal 30a is registered in the telephone directory information of the transmission destination terminal 30b, and transmission. Based on the communication history between the original terminal 30a and the destination terminal 30b, it is determined whether or not to switch the mail destination to the new address of the destination terminal 30b.

  The transfer determination unit 15 first acquires a destination address and a transmission source address by analyzing a mail header of the input mail. Subsequently, the transfer determination unit 15 searches the address storage unit 11 based on the destination address to determine whether the address is a new address (current address) or an old address. At this time, if the destination address of the mail is a new address (current address), the forwarding determination unit 15 determines that the forwarding of the mail is unnecessary and the mail is transmitted as it is. In this case, the transfer determination unit 15 outputs the input mail to the mail transfer unit 16.

  On the other hand, when the destination address is the old address of the destination terminal 30b, the transfer determination unit 15 determines whether or not to forward the mail by switching the mail destination to the new address of the destination terminal 30b. Specifically, the transfer determination unit 15 reads the transfer rule stored in the rule storage unit 14. Subsequently, the transfer determination unit 15 extracts the user ID corresponding to the destination address and the user ID corresponding to the transmission source address from the address storage unit 11. Subsequently, the transfer determination unit 15 extracts user information identified by the extracted user ID, that is, user information of the transmission source terminal 30a and user information of the transmission destination terminal 30b. Then, the transfer determination unit 15 determines whether to perform transfer based on the transfer rule and the two pieces of user information.

  When the user A is the owner of the transmission source terminal 30a and the user B who has changed the mail address as shown in FIG. 3 is the owner of the transmission destination terminal 30b, the transfer determination unit 15 displays the user information shown in FIG. An example in which the necessity of transfer is determined based on the transfer rule No. 5 will be described. It is assumed that the determination timing of the transfer determination unit 15 is August 10, 2007. In this case, since the phone book information of the users A and B is registered with each other, the phone book mutual registration is “present”. Further, when viewing the communication history of the users A and B, since mail transmission / reception is performed between the users A and B on June 5, 2007 and August 1, 2007, the latest communication time is “1”. “There is communication within a month” and the number of communication is “twice”. Therefore, the transfer determination unit 15 determines to perform transfer processing.

  When it is determined that the transfer is necessary, the transfer determination unit 15 extracts the new address “bb2@xxx.ne.jp” of the destination terminal 30b from the address storage unit 11, and inputs the new address and the input mail. Is output to the mail transfer unit 16. On the other hand, when it is determined that the transfer is unnecessary, an instruction signal for transmitting a transmission impossible notification to the transmission source terminal 30 a is generated and output to the mail transfer unit 16.

  The mail transfer unit 16 is means for switching the mail destination to a new address and transferring the mail when the transfer determination unit 15 determines to switch the mail destination. When the new address and mail of the destination terminal 30b are input, the mail transfer unit 16 switches the mail destination to the input new address and transfers the mail to the new address. On the other hand, when an instruction signal for transmitting a transmission impossible notification is input, the mail transfer unit 16 generates a transmission impossible notification indicating that the mail cannot be transmitted and transmits the notification to the transmission source terminal 30a. When only the mail is input from the transfer determination unit 15, the mail transfer unit 16 transmits the mail to the destination address of the mail.

  When the mail transfer unit 16 switches the mail destination to the new address of the destination terminal 30b, the mail from the source terminal 30a is transmitted to the destination terminal 30b, and the user of the destination terminal 30b can read the mail. It becomes possible. Therefore, it can be said that such a mail transfer process is a communication process that enables future communication between the transmission source terminal 30a and the transmission destination terminal 30b.

  The notification determination unit 17 assigns the new address of the transmission destination terminal 30b to the transmission source terminal 30a based on the phone book information and communication history stored in the user information storage unit 12 and the mail received by the mail reception unit 13. It is means for determining whether or not to notify. For example, the notification determination unit 17 determines whether the transmission destination terminal 30b is registered in the telephone directory information of the transmission source terminal 30a, whether the transmission source terminal 30a is registered in the telephone directory information of the transmission destination terminal 30b, and transmission. Based on the communication history between the source terminal 30a and the destination terminal 30b, the necessity of notification of the new address is determined.

  The notification determination unit 17 first acquires a destination address and a transmission source address by analyzing a mail header of the input mail. Subsequently, the notification determination unit 17 searches the address storage unit 11 based on the destination address to check whether the address is a new address (current address) or an old address. At this time, if the destination address of the mail is a new address (current address), the notification determination unit 17 determines that the notification is unnecessary and ends the processing.

  On the other hand, when the destination address is the old address of the destination terminal 30b, the notification determination unit 17 determines whether to notify the source terminal 30a of the new address of the destination terminal 30b. Specifically, the notification determination unit 17 reads the notification rule stored in the rule storage unit 14. Subsequently, the notification determination unit 17 extracts the user ID corresponding to the destination address and the user ID corresponding to the transmission source address from the address storage unit 11. Subsequently, the notification determination unit 17 extracts user information identified by the extracted user ID, that is, user information of the transmission source terminal 30a and user information of the transmission destination terminal 30b. And the notification determination part 17 determines whether the notification of a new address is performed based on a notification rule and two user information.

  When the user A is the owner of the transmission source terminal 30a and the user B is the owner of the transmission destination terminal 30b, the notification determination unit 17 performs notification based on the user information in FIG. 4 and the notification rule in FIG. An example of determining necessity is described. The determination time of the notification determination unit 17 is assumed to be August 10, 2007. In this case, since the phone book information of the users A and B is registered with each other, the phone book mutual registration is “present”. Further, when viewing the communication history of the users A and B, since mail transmission / reception is performed between the users A and B on June 5, 2007 and August 1, 2007, the latest communication time is “1”. “There is communication within a month” and the number of communication is “twice”. Therefore, the notification determination unit 17 determines to perform notification processing.

  When it is determined that the notification is necessary, the notification determination unit 17 extracts the new address “bb2@xxx.ne.jp” of the destination terminal 30b from the address storage unit 11, and the new address and the mail source address (The mail address of the transmission source terminal 30a) is output to the notification unit 18. On the other hand, if it is determined that notification is not required, the notification determination unit 17 ends the process.

  The notification unit 18 is means for notifying the transmission source terminal 30a of the new address when the notification determination unit 17 determines to notify the transmission destination terminal 30b of the new address. Specifically, the notification unit 18 first generates a change notification including the input new address of the destination terminal 30b, and transmits the change notification to the input mail address of the source terminal 30a. The notification unit 18 notifies the transmission source terminal 30a of the new address of the transmission destination terminal 30b, so that the user of the transmission source terminal 30a can transmit mail to the new address. Therefore, it can be said that such a change notification transmission process is a communication process that enables future communication between the transmission source terminal 30a and the transmission destination terminal 30b.

  Next, the processing of the mail transfer system 10 shown in FIG. 2 and the mail processing method according to the present embodiment will be described with reference to FIGS. FIG. 6 is a flowchart showing processing of the mail transfer system 10. FIG. 7 is a flowchart showing details of the transfer process shown in FIG. FIG. 8 is a flowchart showing details of the notification process shown in FIG.

  In the mail transfer system 10, the address storage unit 11 stores a new address (current address) or an old address of the portable terminal 30 (destination storage step). Further, the user information storage unit 12 stores the phone book information and communication history of each portable terminal 30 (registration information storage step). Thereafter, when a mail addressed to another mobile terminal 30 is transmitted from a certain mobile terminal 30, the mail receiving unit 13 of the mail transfer system 10 receives the mail (step S10, receiving step). Subsequently, a mail transfer process is performed by the transfer determination unit 15 and the mail transfer unit 16 (step S20), and a process for notifying the new address is performed by the notification determination unit 17 and the notification unit 18 (step S30).

  Next, details of the transfer process will be described with reference to FIG. First, the transfer determination unit 15 determines whether the destination address of the received mail is a new address (current address) or an old address (step S201). At this time, if the destination address is a new address (current address) (step S202; YES), the transfer determination unit 15 determines that mail transfer is unnecessary and the mail is transmitted as it is. Based on the determination, the mail transfer unit 16 transmits a mail to the new address (current address) (step S203).

  On the other hand, when the destination of the mail is the old address (step S202; NO), the transfer determination unit 15 acquires the transfer rule stored in the rule storage unit 14 (step S204). Subsequently, the transfer determination unit 15 acquires the user ID corresponding to the mail destination address and the transmission source address from the address storage unit 11, and based on these user IDs, the user of each of the transmission source terminal 30a and the transmission destination terminal 30b. Information (phone book information and communication history) is acquired from the user information storage unit 12 (step S205).

  Subsequently, the transfer determination unit 15 determines whether or not to switch the mail destination to the new address of the destination terminal 30b based on the acquired transfer rule, the phone book information of the two terminals, and the communication history (step S206). Judgment step). Specifically, the transfer determination unit 15 determines the presence / absence of phone book mutual registration by checking the phone book information of the two terminals, and checks the communication history of the two terminals to determine the latest communication time and the number of communication. get. Then, the transfer determination unit 15 determines whether or not transfer is necessary by applying the acquired telephone directory mutual registration, the latest communication timing, and the communication count to the transfer rule as shown in FIG.

  When the transfer determination unit 15 determines to switch the destination (step S206; YES), the mail transfer unit 16 switches the mail destination to the new address of the destination terminal 30b and transfers the mail to the new address ( Step S207, processing step). On the other hand, when the destination is not switched (step S206; NO), the mail transfer unit 16 generates a transmission impossible notification and transmits it to the transmission source terminal 30a (step S208).

  Next, a process for notifying the transmission source terminal 30a of the new address will be described with reference to FIG. First, the notification determination unit 17 determines whether the destination address of the received mail is a new address (current address) or an old address (step S301). At this time, if the destination address is a new address (current address) (step S302; YES), the notification determination unit 17 determines that notification of the new address is unnecessary, and ends the process.

  On the other hand, when the mail destination is the old address (step S302; NO), the notification determination unit 17 acquires the notification rule stored in the rule storage unit 14 (step S303). Subsequently, the notification determination unit 17 acquires the user ID corresponding to the mail destination address and the transmission source address from the address storage unit 11, and based on these user IDs, the user of each of the transmission source terminal 30a and the transmission destination terminal 30b. Information (phone book information and communication history) is acquired from the user information storage unit 12 (step S304).

  Subsequently, the notification determination unit 17 determines whether or not to notify the transmission source terminal 30a of the new address of the transmission destination terminal 30b based on the acquired notification rule, the phonebook information and the communication history of the two terminals ( Step S305, determination step). Specifically, the notification determination unit 17 determines the presence / absence of phone book mutual registration by checking the phone book information of the two terminals, and checks the communication history of the two terminals to determine the latest communication time and the number of communication. get. And the notification determination part 17 determines the necessity of notification of a new address by applying the acquired telephone directory mutual registration, the latest communication time, and the communication frequency to a notification rule as shown in FIG.

  When the notification determination unit 17 determines to notify the new address (step S305; YES), the notification unit 18 generates a change notification including the new address of the transmission destination terminal 30b and transmits the change notification to the transmission source terminal 30a. (Step S306, processing step). On the other hand, when the notification determination unit 17 determines not to notify the new address (step S305; NO), the process ends.

  As described above, according to the present embodiment, when a mail addressed to the old address of the destination terminal 30b whose mail address has been changed is received, a history of communication between the source terminal 30a and the destination terminal 30b. Based on the above, it is determined whether or not to switch the mail destination to the new address of the destination terminal 30b. Only when it is determined that the destination is to be switched, the mail destination is switched to the new address.

  By looking at the history of communication between the transmission source terminal 30a and the transmission destination terminal 30b, it is possible to infer the possibility of future communication between those terminals and the familiarity between users performing communication. . For example, if a lot of e-mails are sent and received between a certain mobile terminal in the last month, or if e-mails are sent and received several times a month, users who communicate with each other It is intimate, and it can be expected that mail will be sent and received between these portable terminals in the future. On the other hand, if emails have not been exchanged between certain mobile devices even once in the last six months, the intimacy between users is low, and it is expected that emails will not be sent and received between these mobile devices in the future. it can.

  Therefore, by determining whether or not the destination switching (transfer) is necessary based on the past communication status, it becomes possible for the address changer (the user of the transmission destination terminal 30b) not to transfer the mail that the transfer is not desired. Thus, since the mail transfer system 10 automatically determines whether transfer is necessary, the address changer performs a complicated operation (such as registration of a user who refuses reception) in order to refuse reception of unwanted mail. There is no need to do it.

  In the present embodiment, in addition to the communication history, the presence / absence of registration of the transmission destination terminal 30b in the telephone directory information of the transmission source terminal 30a and the registration of the transmission source terminal 30a in the telephone directory information of the transmission destination terminal 30b Whether or not to switch destinations is determined based on the presence or absence of the destination. It can be said that the telephone directory information reflects the possibility of the future communication with the communication partner and the familiarity. For example, if the mail address of the communication partner is registered in the telephone directory, it can be predicted that there is a high possibility that mail will be transmitted / received to / from the communication partner in the future. Therefore, by determining whether or not to switch the destination in consideration of the telephone directory information in addition to the communication status, the possibility and familiarity of future communication can be estimated more accurately, and the address changer (destination terminal 30b) can be estimated more accurately. The necessity of mail transfer can be determined according to the intention of the user.

  In the present embodiment, the communication history, the presence / absence of registration of the transmission destination terminal 30b in the telephone directory information of the transmission source terminal 30a, and the presence / absence of registration of the transmission source terminal 30a in the telephone directory information of the transmission destination terminal 30b. Based on this, it is determined whether or not to notify the transmission source terminal 30a of the new address of the transmission destination terminal 30b, and the notification process is performed only when it is determined to notify the new address. As a result, it is possible to prevent a new address from being notified to an unspecified number of people, and to notify a new address only to a communication partner or a close partner who has a high possibility of future communication. That is, the security of the new address can be increased. Further, since the necessity of notification is determined based on two types of information, that is, communication history and phone book information, the security of the new address can be sufficiently increased.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.

  In the above embodiment, the transfer determination unit 15 and the notification determination unit 17 determine whether or not the destination switching or notification is necessary based on the two types of information of the communication history and the phone book information. The determination may be made using only the type of information. For example, the transfer determination unit 15 may determine whether or not destination switching (transfer) is necessary based on only the communication history, while the notification determination unit 17 may determine whether notification is necessary based only on the phone book information.

  In the above embodiment, when determining based on the communication history, the transfer determination unit 15 or the notification determination unit 17 uses two types of determination criteria, that is, the latest communication time and the number of times of communication. You may use only. Moreover, you may use the criteria different from the newest communication time and the frequency | count of communication. For example, a criterion of whether or not the interval between two email transmission / receptions recently performed between a specific mobile terminal 30 may be within 3 days, or the communication count for the last six months and the communication for the most recent month may be used. A criterion based on the number of times may be used. As described above, the determination criterion related to the communication history can be set in various forms according to the use or purpose of the system.

  In the above embodiment, the presence / absence of mutual registration is used as the criterion for the phone book information. However, other criteria may be used. For example, in the case of mutual registration, if only the destination terminal registers the email address of the communication partner (source terminal), only the source terminal registers the email address of the communication partner (destination terminal). In the case where both are present, a determination criterion constituted by four stages in the case where the mail address of the communication partner is not registered may be used. Thereby, for example, a process of performing transfer or notification can be executed only when mutual registration is performed and only when the destination terminal registers the mail address of the communication partner. As described above, the determination criteria related to the phone book information can be set in various forms according to the use and purpose of the system.

  In the above embodiment, the transfer determination unit 15 and the notification determination unit 17 check the registration status of the mail address of the communication partner using both the phone book information of the transmission source terminal 30a and the phone book information of the transmission destination terminal 30b. However, it is not always necessary to use two phone book information. For example, the transfer determination unit 15 and the notification determination unit 17 may determine whether transfer or notification is necessary using only the phone book information of the destination terminal 30b whose email address has been changed. For example, the transfer determination unit 15 and the notification determination unit 17 can determine to perform transfer or notification when the mail address of the transmission source terminal 30a is registered in the phone book information of the transmission destination terminal 30b. Further, the transfer determination unit 15 and the notification determination unit 17 can determine whether transfer or notification is necessary based on the presence / absence of registration of the transmission source terminal 30a in the telephone directory information of the transmission destination terminal 30b and the communication history. .

  In the above embodiment, the mail transfer system 10 has the change notification transmission function, but this function may not be provided. In this case, the mail transfer system 10 does not need to include the notification determination unit 17 and the notification unit 18. The present invention is also applicable to a mail processing system having only a change notification transmission function. For example, the address storage unit 11, the user information storage unit 12, the mail reception unit 13, the rule storage unit 14, the notification determination unit 17, and the notification unit 18 in the above embodiment are provided with functional components, and the destination terminal 30 b It is also possible to construct a system that notifies the new address.

  In the above embodiment, the phone book information and the communication history are included in one user information and stored in the user information storage unit 12. However, the phone book information and the communication history are stored in separate storage means. May be.

  Moreover, although the said embodiment was related with the mail transfer system, the data to transfer are not limited to a mail. For example, the present invention may be applied to a telephone transfer mechanism to construct a telephone transfer system similar to the mail transfer system 10. In such a telephone transfer system, the destination information is a telephone number, and the transferred message is data (data including the telephone number of the called party) transmitted by a selection signal or a voice signal.

  Moreover, in the said embodiment, although the communication terminal was the portable terminal 30, the kind of terminal is not limited and fixed terminals, such as a personal computer, may be sufficient.
