A conventional mail delivery method allows a mobile terminal to receive a mail, and a method for delivering a mail to a mobile terminal when a mail server receives the mail. There is a method in which the mail is spooled to a mail server and the mobile terminal periodically checks with the mail server whether the mail has arrived.

[0006] However, when the mobile terminal regularly checks the mail server, it is necessary to periodically check whether or not the mail has arrived at the mail server where the mail is spooled. Many check whether mail has arrived through the public network, and frequent checks are costly, especially for mobile terminals. Conversely, if you do not check too often,
The time from when the mail is spooled to the mail server until the mail is viewed becomes longer.

[0007] Further, when mail is delivered to the mobile terminal when the mail server receives the mail, it is very costly when the mail is delivered through a public network. However, once the mail server is set to send mail to the mobile terminal, it is always sent to the mobile terminal.
If there is a recipient near the terminal, there is no need to send the mail to the mobile terminal, but even in such a case, the mail is sent to the mobile terminal.

[0008] When there is a mobile terminal in the premises,
Even in the case where a mail is transmitted to a mobile terminal without using a public terminal in a wireless RAN or the like, since wireless has a lower data transmission capability than that of a wired terminal, it is better not to flow unnecessary data. Also, since the mobile terminal screen is small and it is difficult to read the mail, it is better to use the terminal when the mail can be viewed on the terminal.

The present invention provides a data communication system capable of transmitting a mail to a mobile terminal when the user is near the terminal when receiving the mail, and transmitting the mail to the mobile terminal through a public network when the user wants to be near the terminal. It is an object to provide an apparatus and a mail delivery method.

[0010]

In order to solve the above problems, the present invention checks the extension number of the mobile terminal owned by the owner of the e-mail address from the address / telephone number correspondence table, and determines the extension number. P to determine if the mobile terminal
By confirming with the BX, the mail delivery destination can be appropriately changed according to the location of the mail address owner.
