BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described through embodiments of the present invention. However, the following embodiments do not limit the claimed invention, and all combinations of the features described in the embodiments are not limited to the scope of the present invention. It is not always necessary for the solution.
[0012]
FIG. 1 is a diagram schematically illustrating the entire wireless communication system according to the present embodiment. The wireless communication system includes mobile terminal devices 10 and 20, a mobile communication network 30, a general public network 40, a mail server 50, an Internet network 60, and a communication terminal device 70.
[0013]
The mail server 50 receives an e-mail from the sender terminal 10 or the communication terminal device 70 via the mobile communication network 30, the general communication network 40, and the Internet 60, for example. The mail server 50 transmits the e-mail received from the sender terminal 10 or the communication terminal device 70 to the recipient terminal 20 having the destination address of the e-mail. In addition, the mail server 50 can receive an e-mail from the sender terminal 10 and transmit the e-mail to the receiver terminal 20 or the communication terminal device 70 having the e-mail destination address.
[0014]
FIG. 2 is a diagram illustrating a functional configuration of the mail server 50 according to the present embodiment. As illustrated, the mail server 50 includes a storage unit 51, an information management unit 52, a search unit 53, a communication unit 54, a determination unit 55, and a mail storage unit 56.
[0015]
The storage unit 51 stores the mail transmitted from the sender side portable terminal device 10, and stores a mail by setting a mailbox for each mail destination (address information).
[0016]
The information management unit 52 is a processing unit that manages address information of each destination of an e-mail registered in advance.
[0017]
The search unit 53 searches the management information of the information management unit 52 based on the mail information received from the sender-side mobile terminal device 10, and obtains address information of the receiver.
[0018]
The communication unit 54 transmits the mail to the receiver-side mobile terminal device 20 based on the address information obtained by the search unit 53 and transmits the mail.
[0019]
The determination unit 55 determines whether or not the mail transmitted by the communication unit 54 has been received by the recipient mobile terminal device 20 and notifies the sender portable terminal device 10 of the determination result via the communication unit 54. Is a processing unit that performs the following. Specifically, if not received, an e-mail with character information indicating that it has not been received, and if received, an e-mail with character information indicating that it has been received, and a process for notifying the sender side portable terminal device 10 is performed.
[0020]
The mail storage unit 56 stores mail information for notifying the determination result of the determination unit 55 to the sender side portable terminal device 10 via the communication unit 54.
