  The DB management unit 33 reads the destination e-mail address from the input e-mail information, and records the read destination e-mail address and the e-mail information in association with each other in the e-mail DB 34 (step Sb2). Next, the DB management unit 33 inputs the information of the recorded email address to the notification unit 35. The notification unit 35 transmits information on the input e-mail address to the SMS transmission unit 42 of the SMS server device 40 (step Sb3). The SMS transmission unit 42 transmits a search request including information on the email address received from the notification unit 35 to the DB management unit 22 of the user information server device 20 (step Sb4).

  The DB management unit 22 searches the user information DB 23 for an entry that includes an e-mail address that matches the e-mail address information received from the SMS transmission unit 42, and includes connection destination identification information and a telephone number included in the searched entry. Is read (step Sb5). Then, the DB management unit 22 transmits a search response including the read connection destination identification information and the telephone number to the SMS transmission unit 42 (step Sb6).

  The SMS transmission unit 42 reads the connection destination identification information from the received search response, and inputs selection instruction information including the read connection destination identification information to the connection unit 41. The connection unit 41 switches the connection to the mobile phone network 10A corresponding to the connection destination identification information included in the input selection instruction information. Next, the SMS transmission unit 42 reads the telephone number from the received search response, makes a call to the mobile phone network 10A based on the read phone number, establishes a line with the mobile phone terminal 50, and is established. An e-mail incoming notification is transmitted through the line (step Sb7).

  The SMS reception processing unit 53 of the mobile phone terminal 50 receives the radio signal including the SMS information transmitted from the base station apparatus 11A, reads the SMS information included in the received radio signal, and performs the SMS information reception process ( Step Sb8). When the SMS reception processing unit 53 detects that the read SMS reception information includes an e-mail arrival notification, the SMS reception processing unit 53 generates an e-mail acquisition request including the e-mail address of the own terminal, and generates the generated e-mail acquisition request. The included radio signal is transmitted to the base station apparatus 11A. The base station apparatus 11A detects that the e-mail acquisition request included in the received radio signal is communication for the Internet network 100, and outputs the e-mail acquisition request to the GW 12A. The GW 12A acquires the e-mail to the Internet network 100. Send a request.

  The e-mail acquisition request is transferred to the e-mail server device 30 through the Internet network 100. The transmission / reception unit 32 of the e-mail server device 30 receives the e-mail acquisition request from the mobile phone terminal 50 via the connection unit 31 and reads the e-mail address information included in the received e-mail acquisition request. Then, the transmitting / receiving unit 32 inputs read instruction information including information of the read e-mail address to the DB management unit 33. The DB management unit 33 searches the e-mail DB 34 for an entry that matches the e-mail address information included in the input read instruction information, and sets the entry that matches the e-mail address information included in the retrieved read instruction information. The included email information is read from the email DB 34 (step Sb10).

  The DB management unit 33 inputs the read electronic mail information to the transmission / reception unit 32, and the transmission / reception unit 32 transmits the electronic mail information input to the Internet network 100 via the connection unit 31 (step Sb11). The electronic mail information is transferred to the GW 12A through the Internet network 100. The GW 12A transmits the received e-mail information to the base station apparatus 11A, and the base station apparatus 11A transmits a radio signal including the e-mail information received from the GW 12A to the mobile phone terminal 50 (step Sb11). The mail receiving unit 54 of the mobile phone terminal 50 reads e-mail information from the received radio signal, and displays the read e-mail information on the screen or records it in an internal storage area.

Here, details of the SMS reception process in step Sb8 in FIG. 5 will be described with reference to FIG. The SMS system related to the SMS reception process described in FIG. 6 is a system standardized by OMA (Open Mobile Alliance) and includes a process for automatic incoming e-mail.
First, the SMS reception processing unit 53 of the mobile phone terminal 50 receives the SMS information (Step Sc1, Step Sb7). The SMS reception processing unit 53 determines whether or not the received SMS information is special SMS information for automatically receiving an e-mail (step Sc2). Here, whether or not it is special SMS information is determined based on information included in the header of the SMS information. When it is determined that the SMS reception processing unit 53 is not special SMS information, the SMS reception processing unit 53 performs a normal SMS reception operation. Here, the normal SMS reception operation refers to an operation for displaying a message included in the received SMS information on a screen (step Sc3).

  On the other hand, if the SMS reception processing unit 53 determines that the information is special SMS information, the SMS reception processing unit 53 then determines whether or not the “email arrival notification” information is included in the header of the SMS information (step Sc4). . If the SMS reception processing unit 53 determines that the “email arrival notification” information is not included in the header of the SMS information, the SMS reception processing unit 53 discards the received SMS information (step Sc5). On the other hand, when the SMS reception processing unit 53 determines that the information of “Email arrival notification” is included in the header of the SMS information, the email address included in the SMS information is set in the mobile phone terminal 50. In step Sc6, it is determined whether or not automatic reception is set. If the SMS reception processing unit 53 determines that the e-mail address included in the SMS information is not set for automatic reception, the SMS reception processing unit 53 discards the received SMS information (step Sc5). On the other hand, if the SMS reception processing unit 53 determines that the email address included in the SMS information is set for automatic reception, the SMS reception processing unit 53 sends an email acquisition request to the Internet network 100 (step Sc7, step Sb9).

  With the configuration of the above-described embodiment, even if the contracted mobile phone carrier is changed, it is possible to continue to use it without changing the e-mail address. In addition, similar to the e-mail service provided by current mobile phone carriers, it is possible to notify the arrival of an e-mail, and the mobile phone terminal equipped with the SMS system standardized by OMA also notifies the incoming call. Can be received and an e-mail acquisition request can be transmitted to the e-mail server device without intervention of a user operation to receive e-mail information from the e-mail server device.

  Also, with the current service of mobile phone carriers, it was necessary to change the e-mail address along with changing the phone number without changing the contracted mobile phone carrier, In the above embodiment, even if the telephone number is changed, it can be continuously used without changing the e-mail address. As a result, when the number portability system is introduced, there is no need to change the e-mail address as well as the telephone number even if the mobile phone carrier is changed, so that there is no barrier to changing the contracting party.

  In addition, the current service of mobile phone carriers cannot use the e-mail service if it is canceled, lost or suspended, or if the mobile phone terminal breaks down. In the configuration of the embodiment, if there is a newly contracted mobile phone terminal or another mobile phone terminal, it is possible to continue to use the email service with the same email address on the mobile phone terminal. .

  In addition, by introducing the joint email server system 200 according to the above-described embodiment, a newly entered mobile phone carrier can start an email service without building an email service system by itself. Is possible. In this case, there may be only one mobile phone network, and the connection unit 41 of the SMS server device 40 is fixedly connected to the one mobile phone network. It can be set as the structure which does not use information.

  Moreover, even if the joint e-mail server system 200 according to the above-described embodiment is introduced, there is no need for an existing mobile communication carrier to change the equipment, and the e-mail service is operated by itself. However, since the traffic of the e-mail information itself does not decrease, there is an effect that there is no economical obstacle in introduction.

  In addition, in a conventional e-mail service operated by a mobile phone carrier, the mobile phone carrier manages if the mobile phone terminal 50 is turned off or out of service area from the base station device. Stored in the server. When the mobile phone terminal is turned on or within range, it is not automatically sent from the server, and e-mail information is sent from the server to the mobile phone terminal at the next retransmission. It is configured. On the other hand, since the SMS system is used in this embodiment, when the power of the mobile phone terminal is turned on or when the mobile phone terminal is in an area, the SMS transmission unit 42 is autonomous about the incoming email notification that could not be notified. To establish a line with the mobile phone terminal 50, and send an incoming e-mail notification through the established line. Therefore, it is possible to receive the e-mail information without a request from the mobile phone terminal 50 operated by the user and without waiting for the next retransmission, and until the e-mail information is received as compared with the conventional case. It becomes possible to shorten the time.

  In the above embodiment, the DB management unit 33 of the e-mail server device 30 outputs the e-mail address information to the notification unit 35. However, the present invention is not limited to this, and the received e-mail information is not limited thereto. If the UID is included, the UID is output to the notification unit 35, and the SMS transmission unit 42 may perform the subsequent processing using the UID instead of the e-mail address. If the received e-mail information includes a UID, the e-mail DB 34 also stores e-mail information in association with the UID instead of the destination e-mail address, and the UID is included in the e-mail acquisition request. May be included.

  In the above embodiment, the e-mail acquisition request includes an e-mail address. However, the present invention is not limited to this embodiment, and a password set by the user himself / herself may be included. In that case, the information included in the e-mail acquisition request is a combination of an e-mail address and a password or a combination of a UID and a password. At this time, the information stored in the email DB 34 is a combination of an email address, a password, and email information, or a combination of a UID, password, and email information. Then, the DB management unit 33 determines whether or not the password included in the e-mail acquisition request matches the password stored in the e-mail DB 34.
