A second mail storage unit 52 for storing mail handled by the two-mail application is provided.

  Next, a mail communication processing method in the mail communication system 100 configured as described above will be described.

  First, in the mail communication system 100 shown in FIG. 1, the user of the mobile phone 10 performs an operation for transmitting the mail A toward the mobile phone 20 using the first mail application. The first mail application adds “A” which is the application ID of the first mail application to the data of the mail A to be transmitted, and transmits the mail C via the transmitting / receiving unit and the antenna of the mobile phone 10.

  Next, the user uses the second mail application and the third mail application to transmit mail B and mail C, respectively, similarly to the first mail application. Here, the application ID “B” is added to the mail B, and the application ID is not added to the mail C. Mail A, mail B, and mail C are transmitted to the mobile phone 20 via the base station 41, the mobile communication network 40, and the base station 42.

  On the other hand, the mobile phone 20 receives the mail A, mail B, and mail C with the first mail application activated. As shown in FIG. 6, when the mail reception distribution unit 36 receives the mail A, the mail B, and the mail C via the antenna 17 and the transmission / reception unit 22, the mail A including the application ID “A”, and The mail B including the application ID “B” is stored in the second mail storage unit 52, and the mail C including no application ID is stored in the first mail storage unit 51. FIG. 7 shows a state where each mail is stored.

  Since the mail for the third mail application of the basic processing section 32 has been received, the mail reception distribution section 36 displays on the display section 13 that the mail for the third mail application has been received and notifies the user. To do. Returning to FIG. 6, the mail reception distribution unit 36 notifies the active first mail application that the mail has been received. On the other hand, since the second mail application has not been activated, the reception is not notified.

  The first mail application that is notified that the mail has been received makes an acquired mail determination request to the acquired mail determination unit 37 with the application ID “A” as an argument. The acquired mail determination unit 37 that has received the mail determination request searches the mail stored in the second mail storage unit 52 for the mail with the application ID “A” and determines that the mail A is to be acquired. Then, a response to that effect is returned to the first mail application as a result of the acquired mail determination.

  Here, since the mail C is a mail to be acquired by the mail application C of the basic processing unit stored in the first mail storage unit, it is not a determination target for the acquired mail determination unit 37. Further, the mail B stored in the second mail storage unit has the application ID “B”, and therefore the acquired mail determination unit 37 does not determine that the mail should be acquired.

  In the case of an acquired mail determination response indicating that there is no mail to be acquired, the first mail application ends the mail acquisition process. On the other hand, in the case of a response indicating that there is a mail to be acquired, a request to acquire mail A is made to the mail acquisition unit 38 as shown in FIG. Upon receipt of the mail acquisition request, the mail acquisition unit 38 confirms that the mail A is a mail to be acquired, acquires the mail A from the second mail storage unit 52, and sends the mail A to the first mail application. Send mail response with data.

  Subsequently, the mail acquisition unit 38 deletes the mail A acquired by the first mail application from the second mail storage unit 52. On the other hand, the first mail application that has received the mail acquisition response displays the contents of the acquired mail. As is clear from the operation of FIG. 6, the first mail application installed in the mobile phone 20 has a function of acquiring and displaying the mail received during activation without a user instruction.

  Thereafter, as shown in FIG. 8, the user activates the second mail application, operates the operation unit 12, and performs an operation for confirming the received mail. The second mail application that receives the notification of the mail confirmation operation from the operation unit 12 uses the application ID “B” as an argument to the acquired mail determination unit 37 of the basic processing unit 32, as in the case of the first mail application. Make an acquisition mail judgment request. Receiving the acquired mail determination request, the acquired mail determination unit 37 searches the mail stored in the second mail storage unit 52 for the mail with the application ID “B” and determines that the mail B should be acquired.

  Subsequently, the acquired mail determination unit 37 responds to the second mail application as a result of the acquired mail determination. The second e-mail application that has received the response to the acquired e-mail determination displays the “subject” of the e-mail on the display unit 13 when there is an e-mail to be acquired, and if there is no e-mail to be acquired, A message to that effect is displayed on the display unit 13. When the user who has confirmed the display of the “subject” of the mail to be acquired performs an operation for acquiring the received mail B, the second mail application received from the operation unit 12 receives the mail acquisition unit 38. Request to obtain mail B.

  The mail acquisition unit 38 that has received the mail acquisition request confirms that the received mail B is the mail to be acquired, as in the case of the first mail application, and receives the mail B from the second mail storage unit 52. Obtain and send a mail acquisition response together with the mail B data to the second mail application. Subsequently, similarly to the first mail application, the mail acquisition unit 38 deletes the mail B acquired by the second mail application from the second mail storage unit 52.

  On the other hand, the second mail application that has received the mail acquisition response displays the contents of the acquired mail. As is apparent from the operation of FIG. 8, the second mail application installed in the mobile phone 20 has a function of acquiring and displaying the received mail when a user command is issued.

  As described above, in this embodiment, the mobile phone 10 uses the first mail application and the second mail application of the versatile mail application unit 31 and the third mail application of the basic processing unit 32, respectively. Mail A and mail B to which application IDs “A” and “B” are added, and mail C to which application IDs are not added are transmitted. The mobile phone 20 receives the mail A, the mail B, and the mail C while the first mail application 33 is activated, and the received mail A and the mail B are stored in the second mail storage unit 52. It is stored in the first mail storage unit 51.

  The mail reception allocating unit 36 notifies the activated first mail application of mail reception. Upon receiving the notification, the first mail application 33 first requests the acquired mail determination unit 37 to determine the acquired mail and receives a response indicating that there is a mail to be acquired. The mail is acquired with respect to the mail acquisition unit 38 and the mail A is acquired. The acquired mail A is displayed on the display unit 13.

  Next, when the second mail application is activated and the received mail is checked, the second mail application requests the acquired mail determination and there is a mail to be received as in the first mail application. Receive the response. The second mail application displays the “subject” of the mail. Subsequently, when the operation for acquiring the displayed mail is performed, the mail acquisition unit 38 acquires the mail determined to be acquired, and the mail B is acquired. The acquired mail A is displayed on the display unit 13.

  Therefore, according to the present embodiment, since the user can use a general-purpose mail application that does not depend on the platform, the user can select a mail application that meets his needs from various mail applications, and Even if the mobile communication terminal changes, the same mail application can be used. In addition, since it has a mail storage unit separate from the mail storage unit of the mail application of the basic processing unit, it can acquire only the mail of the same application, so that the confidentiality of the mail content is improved and only necessary mail is received Can do. In addition, since confidentiality between mail applications is high, it is possible to provide application programs having various functions that meet the needs of users.

  In this embodiment, the acquired mail determination and the mail acquisition are different sequences, but it is needless to say that one sequence may be used.

  Further, in the present embodiment, the first mail application acquires and displays mail even if there is no user instruction, and the second mail application acquires and displays mail when there is a user instruction. However, it is needless to say that the present invention can also be applied to the case where an application that performs processing other than the first and second applications is used by downloading an application that performs various processing.

  In the present embodiment, the application ID is used as the identifier. However, it is needless to say that the application ID can be applied even if another identifier such as a port number is used.
