2. Description of the Related Art Nowadays, personal computers and personal digital assistants have become widespread, and there are many opportunities to use electronic mail as a means of communication. Email allows the sender to send information without worrying about the recipient's convenience,
It is also a convenient tool for the recipient to read the received information at any time.

However, while e-mail is convenient, if the recipient is not present at the place where the terminal device he or she normally uses is sent by e-mail, it is highly urgent.
Or important information becomes meaningless.
In such a case, it suffices if the sender can send the mail to the mail address of the place where the recipient exists, but if the sender does not know the mail address in advance, the sender cannot send the email.

In such a case, it is convenient for the recipient to use a mail transfer function that can be used as a service such as a mail server to transfer the mail addressed to him / herself to the mobile phone terminal he / she owns. Is. When using this mail transfer function, the server administrator will be requested to set the transfer.

[0005]

However, since the conventional setting of the mail transfer is only ON / OFF of the transfer,
All the e-mail addressed to me is transferred, and even the mail that is less important to the recipient will be received by the transfer destination terminal device such as the mobile phone terminal. In addition, depending on the transfer destination terminal device used, the number of characters of the received mail is limited, and a large-sized electronic mail cannot be received, and the excess portion may be discarded.

[0006] The present invention has been made to solve the above problems, and even if the recipient is not in the environment of the terminal device that he or she normally uses, e-mail or the like sent to the recipient can be sent. An object of the present invention is to provide a data transfer method, a device therefor, and a network system that allow information to be freely read when data is needed in other environments.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing the configuration of a system for implementing the data transfer method of the present invention. The in-house network 1 is composed of a data transfer device 2, a mail server 3, terminals 4a, 4b, ... 4n, and a concentrator 5 for concentrating these to connect to an outside network. In terms of aspects, access from outside is restricted. The access is restricted by giving an ID or password to the user of the in-house network 1, for example.

The in-house network 1 is a network such as a LAN, and is connected to an outside network by a network such as the Internet. Data transfer device 2
Is an information processing terminal that performs processing for transferring an electronic mail addressed to each user of the terminal 4 to a transfer destination desired by the user. The mail server 3 is an information processing terminal that stores electronic mail sent to each terminal 4 via the concentrator 5. Each terminal 4 is an information processing terminal possessed by each user, and is a terminal equipped with a display screen, a keyboard, a browser function, and other functions necessary for sending and receiving electronic mail.

The data transfer service of the present invention will be briefly described below. Here, a case where a user having the terminals 4a to 4n uses the transfer service in the company network 1 will be described. First, the user registers the mail address of any of the terminals 4a to 4n that he / she owns in the data transfer device 2 as a premise to use the transfer service. The user can receive the transfer service by making this registration.

Now, for example, a user of the terminal 4a is going outside, and the user has, for example, an attachment file "none" in the electronic mail addressed to his / her terminal 4a, and the data size of the mail is A or less. Suppose that you want to receive only the short emails of the above on your own mobile phone terminal. The e-mail addressed to me is stored in the mail server 3, and the e-mail addressed to me is selected from among the e-mails addressed to my terminal 4a in the mail server 3 and data is sent to the e-mail address of the mobile phone terminal. The transfer device 2 will be requested.

The data transfer device 2 receives the transfer request from the user as an "incoming inquiry mail". That is, in the case of the incoming inquiry mail from the registrant who provides the transfer service, the data transfer device 2 transfers all the e-mail addressed to the registrant from the mail server 3 to itself (the data transfer device 2), and Detects an e-mail that meets the conditions for transferring from inside (in the above example, the attached file is "none" and the mail size is A or less), and the destination address of the corresponding e-mail (the mail address set in the terminal 4a) ) Is rewritten to the forwarding mail address (mobile phone terminal mail address) and the e-mail is sent. As a result, the user can receive the necessary e-mail transfer without having to set the transfer destination in the mail server 3 one by one.

Next, the configuration of the data transfer device 2 of the present invention will be described with reference to FIG. FIG. 2 is a block diagram showing an internal configuration of the data transfer device 2 shown in FIG. The data transfer device 2 includes a data receiving unit 10 and a control unit 1.
1, a transfer condition storage unit 12, a data analysis unit 13, an address search unit 14, a registration data storage unit 15, a received mail storage unit 16, a data comparison unit 17, and a data transmission unit 18. ing.

A user who has previously registered the mail address of his / her own terminal 4 in the data transfer device 2 makes an incoming inquiry for an e-mail addressed to himself / herself using a predetermined mail format addressed to the data transfer device 2. . This allows the data transfer device 2 to pick up the received mail that has arrived at the mail server 3 and transfers only the necessary e-mail to the transfer destination according to the transfer conditions described in the incoming call waiting mail. Let

The data receiving unit 10 receives the incoming inquiry mail valid only for the data transfer device 2 and the electronic mail from the mail server 3, and notifies the control unit 11 of the reception. The control unit 11 includes the data receiving unit 10
If the received mail is an incoming inquiry mail, the incoming mail is stored in the transfer condition storage unit 12, while the received mail is a forwarded mail from the mail server 3. For example, this is stored in the received mail storage unit 16.

When the incoming inquiry mail is stored in the transfer condition storage unit 12, the control unit 11 notifies the data analysis unit 13 of the end of storage. Upon receiving this notification, the data analysis unit 13 extracts the “source mail address (mail address of the terminal 4)” and the “transfer condition” from the incoming inquiry mail stored in the transfer condition storage unit 12. To do. The address search unit 14 searches the mail address data registered in the registration data storage unit 15 by using the “source mail address (mail address of the terminal 4)” extracted by the data analysis unit 12, and transfers the data. The control unit 11 is notified of the search result as to whether or not the person is a target person (registered person).

The control unit 11 also outputs a command to the data comparison unit 17 when the incoming inquiry mail is from the transfer service target person. This command is a command to detect a transfer mail that matches the “transfer condition” analyzed by the data analysis unit 13 among the transfer mails from the mail server 3 stored in the received mail storage unit 16.
The data comparison unit 17 receiving this instruction compares each transfer mail with the above-mentioned "transfer condition", and notifies the control unit 11 of the storage destination address of the mail in the received mail storage unit 16 corresponding to the transfer condition. .

Further, the control unit 11 controls the received mail storage unit 1 based on the storage destination address notified from the data comparison unit 17.
The corresponding transfer mail is read from 6, the transmission destination mail address described in the transfer mail is changed to the transfer destination address, and the transfer mail is transmitted from the data transmitting unit 18. As a result, the mail addressed to the user received by the mail server 3 is transferred to the transfer destination address.

Next, the processing flow of the data transfer service according to the present invention will be described with reference to FIGS. Figure 3
6 is a flowchart showing a detailed transfer processing procedure in the data transfer device 2. First, when the data receiving unit 10 of the data transfer device 2 receives the incoming inquiry mail from the user via the concentrator 5 (step S1), a reception notification is sent to the control unit 11, and the control unit 11 receives this notification. It is determined whether the received mail is an incoming inquiry mail (step S2).

In this case, since the electronic mail is an incoming inquiry mail (step S2 YES), step S
The process proceeds from step 2 to step S3, and this incoming inquiry mail is stored in the transfer condition storage unit 12. And step S4
Then, the sender email address B (the email address of the terminal 4) is extracted. Next, in step S5, the "transfer condition" described in this incoming inquiry mail is extracted. In this example, it is assumed that the transfer condition is that the received mail size is A or less and the presence / absence of an attached file is “absent”.

In the next step S6, the sender's mail address B (mail address of the terminal 4) is searched, and in step S7 it is determined whether or not the user is a registrant of the transfer service and the use of one of the terminals 4, that is, the terminal 4. It is determined whether the person is a person. If the user is not a registrant, the process proceeds to step S8, an unregistered notification mail is created for the mail address C of the mobile phone terminal that is the incoming call inquiry destination, and this unregistered notification mail is transmitted in step S9. By doing so, the user is notified that the mail address of the terminal 4 he / she has is incorrect, and a new incoming inquiry can be made by inputting the correct mail address.

The sender's mail address B (mail address of the terminal 4) in the incoming inquiry mail from the registrant
Is registered in the registration data storage unit 15, the process proceeds from step S7 to step S10,
The mail server 3 is requested to transfer the e-mail that has been sent to the sender mail address B (the mail address of the terminal 4) and has already been stored. As a result, if an email is being sent to that user,
The received mail is transferred to the data transfer device 2.
On the other hand, if no e-mail addressed to the user is received and the received e-mail is not transferred to the data transfer device 2 for a certain period of time, “no reception” is sent to the e-mail address of the mobile phone terminal that has transmitted the incoming inquiry mail. Is notified (step S19).

If there is a transfer mail addressed to the user, this transfer mail is received in step S1. Since this transfer mail is an electronic mail based on the request in step S10, the determination in step S2 is negative (NO), and the process proceeds from step S2 to step S11. This step S1
At 1, the electronic mail transferred from the mail server 3 is stored in the received mail storage unit 16. Then, by the processing described below, the received mail required by the user is selected by comparing this transferred mail with the transfer conditions in the incoming inquiry mail of the user.

That is, in step S12, the transfer conditions previously extracted are read from the data analysis unit 13 and the received mail transferred from the mail server 3 is read from the received mail storage unit 16 (step S13).
Next, it is determined whether or not the size of the received mail is A or less (step S14). If the size exceeds A, the transfer conditions are not met, so the process proceeds to step S18, and there is a next received mail. If there is, the next received mail is taken out (step S18 “Yes”, step S14).

If the size of the received mail is A or smaller, the presence or absence of the attached file is determined in step S15. If the attached file exists, the transfer conditions are not met and the process proceeds to step S18. If there is, the process returns from step S18 to step S13, and the process of reading the next e-mail is repeated.

On the other hand, if there is no attached file (step S15 "none"), the received mail meets the transfer conditions, and therefore the storage address of the received mail in the received mail storage unit 16 is notified to the control unit 11. (Step S1
6) The destination mail address B of the received mail (the mail address of the terminal 4) is rewritten to the mail address C of the mobile phone terminal which is the sender of the incoming inquiry mail, and then the received mail is transmitted (step S17). ).
Note that the forwarding mail address may be configured so that another terminal can be designated in the incoming inquiry mail.

After step S17, the process proceeds to step S18, it is determined whether there is the next received mail, and if there is no received mail, the process returns to step S1 (step S1).
18 “none”), and thereafter waits for receipt of an incoming inquiry mail from the user and a transfer mail from the mail server 3. By performing the above processing, it is possible to transfer the received mail that meets the transfer conditions specified by the user to the transfer destination desired by the user. If the user who once received the transfer service of the received mail by the data transfer device 2 wants to receive the rest of the e-mail, the user must send an incoming inquiry mail newly specifying the transfer conditions to the data transfer device 2. Now you can receive the rest of your email.

Regarding the method of transmitting the incoming inquiry mail, for example, when transmitting from a mobile phone terminal, a screen for inputting transfer conditions etc. is displayed when the data transfer device 2 is accessed. It is preferable that the condition is set so that the condition can be selected from options. Further, it is preferable to have a function of automatically entering the mail address of the terminal 4 of its own.

The data transfer service of the present invention is not limited to the above embodiment, and various modifications can be considered. In the above embodiment, the data transfer is performed in the in-house network, but the present invention can be applied to the e-mail service of a general telecommunications carrier.
In this case, it can be carried out if the telecommunications carrier as the provider registers the mail address of the user in the data transfer device 2. In this case, the telecommunications carrier can expect a secondary effect such as an increase in the number of users by implementing the transfer service as a service associated with the electronic mail service.

[0035]

As is apparent from the above description, according to the present invention, it is only necessary to register the e-mail address of the user who wants to use the transfer service in the data transfer device, and to request only the e-mail to be transferred. Can be transferred to the destination. Therefore, unlike the conventional transfer service, it is not necessary to perform useless electronic mail transfer processing.
