Alternatively, a plurality of programs in any combination may be stored. Here, it is assumed that all of these five programs are stored.

It should be noted that the processing executed by the control processing section 130 with reference to these programs may be realized by using a dedicated integrated circuit. Next, FIG. 4 shows a flowchart of the e-mail transfer process. Hereinafter, the flow of the e-mail transfer process will be described with reference to FIGS.

The electronic mail transmitted via the Internet 2a is received by the Internet mail server 20 (S41). The e-mail transfer device 10 logs in to the Internet mail server 20 at regular time intervals using the mail account of each user 31 stored in the user information database 140, and
A transmission request is made when there is an e-mail addressed to No. 1. The e-mail received by the transmitting / receiving device 110 is stored in the mailbox 160 (S42).

For this electronic mail, first, the control processing section 130 refers to the electronic mail selection program 120a to start the electronic mail selection processing (S43). In the e-mail selection program 120a, an e-mail satisfying a predetermined selection condition is selected according to the user settings stored in the user setting storage means 14.

In the user information database 140, processing conditions set by the user 31 for each mail account of the user 31 to be received are stored. As selection conditions for the processing of the e-mail selection program 120a, a character string to be searched in the e-mail and a part in the e-mail to search for this character string are specified.

The search location may be, for example, the sender name of the electronic mail, the sender's mail account, the subject, the address of the sender server, a part or all of the text, the address of the transfer destination, and the like. A plurality of search location conditions may be specified. If the set string exists in this specified search location,
This email is retrieved as the forwarded email, and the other emails are deleted from the mailbox. Only important emails are selected by the user,
Unnecessary e-mails are deleted and are not finally transmitted to the mobile phone 3a.

It should be noted that the user setting for the subsequent processing is collectively performed every time the search condition character string or the search location is specified in the electronic mail selection processing.
40 may be stored. As a result, the same processing is performed for e-mails selected under the same selection conditions in the e-mail selection processing. For example, the e-mail from Mr. A is the mobile phone 3a
All the contents are received, but the e-mail from Mr. B can be specified for each e-mail sender so that only the important parts are extracted and received by the processing described later. It is possible. If the user has subscribed to a plurality of mobile phone services, the processing content can be set for each of the mobile phone mail servers 30 to which the user is transferred.

Next, the attached file deletion program 120
With reference to b, if a file is attached to the e-mail, an attached file deletion process is performed to delete this file (S44). As a result, the amount of data finally transmitted to the mobile phone 3a is reduced.

As the user setting, designation of whether or not to delete all attached files and the file format of the file to be deleted may be designated. The destination information database 1 is used as destination information for each address of the mobile phone mail server 30 that transmits a file format that cannot be browsed by the mobile phone 3a to the mobile phone 3a.
50, and according to the transfer destination information,
The attached file to be deleted may be automatically selected. The transfer destination information is manually input by the service provider of the e-mail transfer device 10 from the input device 151, for example.
As a result, automatically without user setting,
Attachments that cannot be viewed are deleted and mobile phone 3
a.

Next, the e-mail conversion program 120c
Is referred to, an electronic mail conversion process for converting the electronic mail into a format that can be viewed on the mobile phone 3a is started (S45). As a result, even when the format of the transmitted e-mail is different from the format received and browsed by the mobile phone 3a, the user can reliably browse necessary information.

For example, the sender name, transmission date and time, CC (Carb
Information described in the head attached to the e-mail, such as the e-mail address or name recorded in “on copy”, may not be browsed on the mobile phone 3a. When the user 31 wants to browse, the user 31 sets the target information, and the necessary information is written in the body of the e-mail in accordance with the information.

The type of header information that cannot be browsed by the portable telephone 3a is stored in the destination information database 150 as destination information for each address of the portable telephone mail server 30 to be transmitted to the portable telephone 3a. Alternatively, a part that cannot be browsed may be automatically written in the body of the e-mail according to the transfer destination information.

Next, the character number compression program 120d is referred to, and a character number compression process for deleting unnecessary parts designated by the user from the electronic mail and compressing the entire character number is started (S46). As a result, the amount of data ultimately received by the mobile phone 3a is reduced, and the user can browse the minimum necessary e-mail content and understand the gist of the content.

For example, a character string to be deleted from the e-mail is set in the user information database 140, and the character string is deleted by searching the e-mail. As this character string, a decorative character or a blank portion can be specified. Alternatively, not only a character string but also a quoted portion from another e-mail may be specified. In this case, in the text of the e-mail, delete the part where the first character of the line is “>”, or recognize the part with this symbol at the beginning as a quoted part, and , Only a portion exceeding a predetermined number of characters or lines may be deleted. Through these processes, the user can understand the gist of the content of the e-mail, and if necessary, receive the e-mail again later using a personal computer or the like and view the full text.

Next, the e-mail division program 120e
, The e-mail division is started by dividing the e-mail into a predetermined number of characters according to the user setting and recreating the e-mail as a plurality of e-mails (S47). By the e-mail sending and receiving service provided by the telephone office 3,
In some cases, the number of characters per email that can be received by the mobile phone 3a is limited due to the limitation of the memory capacity of the mobile phone 3a. Subsequent contents may be deleted. In order to prevent this, according to the setting of the user 31 stored in the user information database, the body of the e-mail is divided for each predetermined number of characters, and each is created as a separate e-mail. Alternatively, the number of characters of one receivable e-mail is stored in advance in the destination information database 150 for each mobile phone mail server 30 of the transfer destination, and the transfer destination of the received e-mail is accordingly stored. Judge
The electronic mail may be automatically divided into receivable characters. By such a process, even when an e-mail having the number of characters or more that can be received by the mobile phone 3a is transmitted to the user 31, the contents can be completely browsed without any loss.

The number of divisions and the number may be written in the subject of each divided e-mail. For example, "1/3" or "2/3" at the end of the subject
, And the first and third divided parts are indicated, respectively, so that the user can recognize that the e-mail is divided and can easily read the e-mail.

When all the requested processes are completed by the user settings stored in the user information database 140, the e-mail is sent to the designated mobile phone mail server 3.
0 (S4).
8). The e-mail is temporarily stored in a mailbox in the mobile phone mail server 30 via the telephone line 2b and then immediately transmitted, and then transmitted from the transmission device of the wireless base station to the user's portable telephone 3a via the dedicated line ( S49). The mobile phone 3a can receive this e-mail in the standby state, and is viewed on a display device such as a liquid crystal display (S50). If the e-mail is not received because the mobile phone 3a is turned off, the e-mail is sent to the mobile phone mail server 30.
The mail is temporarily stored in the mail server and transmitted again after a predetermined time has elapsed.

As described above, the e-mail processed by the e-mail transfer device 10 has a part of the text or an attached file deleted, or is selected from the arrived e-mails and transferred. . For this reason, it is often necessary for the user to read the processed e-mail using the portable telephone 3a while away from home, for example, and then return to the home or office to read all the unprocessed e-mails again. Therefore, when transmitting the arriving e-mail to the e-mail transfer device 10, it is desirable that the Internet mail server 20 be set not to delete the e-mail from the mailbox in the Internet mail server 20 for a certain period of time.

Further, various electronic mail processing programs in the electronic mail transfer device 10 may be stored in the Internet mail server 20 and realized as one computer device. In this case, for example, the process of transferring an e-mail to the mobile phone 3a can be a kind of service provided by the Internet provider 2.

On the contrary, the above-described electronic mail processing program is stored in the mobile telephone mail server 30, receives the electronic mail arriving in the Internet mail server 20, and transfers it to the mobile telephone 3a. It may be realized as a kind of service provided by the telephone station 3.
