Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mail data sharing system in which various terminal devices such as a mobile phone, a mobile terminal, and a personal computer share mail data and have a common e-mail function. The present invention relates to a mail data sharing system for sharing mail data and holding an e-mail function in common when terminal devices send and receive e-mails in an Internet environment or an intranet environment.
[0002]
[Prior art]
As a technique for sharing mail data among a plurality of terminal devices, for example, a technology is known in which telephone directory information of a mobile phone is backed up to a personal computer via a data center (for example, see Patent Document 1). That is, the telephone directory information possessed by the mobile phone is transmitted to the personal computer via the data center, and the personal computer edits the telephone directory information and replies to the mobile telephone via the data center. As a result, the mobile phone can acquire the telephone directory information from the personal computer and overwrite it as needed. In this case, since the telephone directory information is converted into a CSV (Comma Separated Value: comma-separated value) format between the mobile phone and the personal computer, the mobile phone does not need to use a dedicated program to perform data conversion. Can be.
[0003]
Further, as another example, a terminal device that does not store ISP (Internet Service Provider) information or mail account information uses a memory card storing ISP information or mail account information to itself to use the e-mail function. Is known (for example, refer to Patent Document 2). If the mail data is stored in the memory card in advance, the terminal device can fetch the mail data from the memory card and send the e-mail, and the mail data received by the terminal device can be stored in the memory card. It can be updated by overwriting. In the case of this technology, since the terminal device does not have a CSV format conversion function, the terminal device needs to have a dedicated program for data conversion.
[0004]
FIG. 3 is a conceptual diagram of a conventional data transfer system having no CSV conversion function. In other words, this figure shows the concept of a data transfer system in the case where data conversion is performed between the personal computer 11 and the mobile phone 12 to transfer data. As shown in FIG. 3, in the conventional data transfer system without the CSV conversion function, when the mail data is shared between the personal computer 11 and the mobile phone 12, the communication between the personal computer 11 and the mobile phone 12 is performed. The connection is made with a dedicated cable 13 or a general-purpose cable. Then, after the e-mail function is started by the mailer (e-mail software) 15 provided in the personal computer 11, the data is converted by the data transfer / conversion program 14, and then the mail data is transferred to the mobile phone 12. The mail data is shared between the personal computer 11 and the mobile phone 12 for use.

[0006]
[Problems to be solved by the invention]
However, as shown in FIG. 3, the method in which the personal computer 11 performs data conversion using the data transfer / conversion program 14 and then transfers the data has the following various problems. The first problem is that when mail data is shared and used, it is necessary to perform a transfer process between a plurality of terminal devices such as a personal computer 11 and a mobile phone 12, so the data is transferred and the mail data is shared. To do so, a plurality of terminal devices are required. For this reason, when the terminal devices are frequently used, wasteful processing may be required to transfer the mail data, or the communication system may be congested. The second problem is that the mobile information system including the mobile phone 12 has a small memory size, and thus has a limited storage capacity for mail information. Therefore, when data is transferred from a system having a large storage area such as the personal computer 11, it may not be possible to transfer all data to a mobile information system such as the mobile phone 12.
[0007]
Further, in the technique disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2000-330904), an electronic mail function is activated by one terminal device taking in ISP information and mail account information from a memory card without using a plurality of terminal devices. However, if the terminal device is not provided with a CSV format conversion function and the terminal device is small, such as a mobile phone, it cannot be provided with a data transfer / conversion program as shown in FIG. Therefore, although the minimum e-mail information such as ISP information and mail account information can be captured from the memory card, it is not possible to capture all desired mail data while converting the data. In the technique disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2001-177624), since a portable terminal and a personal computer communicate wirelessly, a dedicated cable as in the system of FIG. There is a problem that at least two terminal devices are required to share the terminal. Further, the problem of wasting communication resources every time data transfer is performed between a plurality of terminal devices is not solved.
[0008]
The present invention has been made in view of the above circumstances, and an object of the present invention is to eliminate a data transfer processing operation and to use a large amount of mail data by sharing it among a plurality of terminal devices. Another object of the present invention is to provide a mail data sharing system.
