Thereafter, as shown in FIG. 11B, the display control unit 155 deletes the callback request icon 12a from the display unit 12 (step S403).

  The network side device 21 transmits a mail transmission completion notification indicating that the transmission of the mail addressed to the receiving terminal 10b is completed to the transmitting terminal 10a (step S404).

  According to the mobile communication system 3 according to the third embodiment, the display control unit 155 of the receiving terminal 10b receives the callback request icon 12a from the display unit 12 in response to the callback release request notified from the calling terminal 10a. to erase. For this reason, it is possible to prevent the user of the transmission terminal 10a from performing a callback that is unnecessary due to circumstances such as completing a request by e-mail or the like.

  Also, according to the mobile communication system 3 according to the third embodiment, the callback request icon 12a is displayed until the display control unit 155 of the receiving terminal 10b acquires the callback release request notified from the calling terminal 10a. Is continuously displayed without being erased from the display unit 12, so that it is possible to prevent a necessary callback from being forgotten.

[Fourth Embodiment]
Next, a mobile communication system 4 according to a fourth embodiment of the present invention will be described focusing on differences from the mobile communication system 1 according to the first embodiment.

  In the mobile communication system 4 according to the fourth embodiment, when the display control unit 155 of the receiving terminal 10b acquires the non-callback request (non-turnback transmission request) notified from the transmitting terminal 10a by the acquiring unit 154, Based on whether or not the callback request icon 12a is displayed on the display unit 12, the callback request icon 12a is deleted from the display unit 12, or a non-callback request icon 12b (non-callback transmission request icon) is displayed. It is displayed on the display unit 12.

  Specifically, the notification unit 153 of the transmission terminal 10a notifies the non-callback request to the reception terminal 10b. Here, the non-callback request indicates that no callback is required.

  The acquisition unit 154 of the receiving terminal 10b acquires the non-callback request notified from the transmitting terminal 10a. Further, the acquisition unit 154 updates the necessity of callback stored in the storage unit 13 in association with the identification information of the transmission terminal 10a to “No” based on the acquired non-callback request (see FIG. 5). .

  The display control unit 155 of the receiving terminal 10b determines whether or not the callback request icon 12a is displayed on the display unit 12. When the callback request icon 12a is displayed on the display unit 12, the callback request icon 12a is deleted from the display unit 12 in response to the non-callback request acquired by the acquisition unit 154. On the other hand, when the callback request icon 12a is not displayed on the display unit 12, the display control unit 155 responds to an incoming call from the transmission terminal 10a that is a notification source of the non-callback request among the incoming calls that the user cannot respond to. Then, as shown in FIG. 12, a non-callback request icon 12b indicating that a non-callback request is notified for the incoming call is displayed on the display unit 12.

  FIG. 13 is a flowchart showing the operation of the receiving terminal 10b in the mobile communication system according to the fourth embodiment of the present invention.

  As illustrated in FIG. 13, the acquisition unit 154 of the receiving terminal 10b acquires the non-callback request notified from the calling terminal 10a (step S501).

  The display control unit 155 of the receiving terminal 10b determines whether or not the callback request icon 12a is displayed on the display unit 12 (step S502).

  When the callback request icon 12a is displayed on the display unit 12, the display control unit 155 of the receiving terminal 10b displays the callback request icon 12a from the display unit 12 in response to the non-callback request acquired in step S501. Erasing is performed (step S503).

  When the callback request icon 12a is not displayed on the display unit 12, as shown in FIG. 12, the display control unit 155 of the receiving terminal 10b displays a non-callback request corresponding to the non-callback request acquired in step S501. The icon 12b is displayed on the display unit 12 (step S504).

  According to the mobile communication system 4 according to the fourth embodiment, when the display control unit 155 of the receiving terminal 10b displays the callback request icon 12a on the display unit 12, the non-call notified from the calling terminal 10a. In response to the back request, the callback request icon 12a is deleted from the display unit 12. For this reason, it is possible to prevent the unnecessary callback from being performed again due to circumstances such as the situation where the user of the transmission terminal 10a does not want the callback.

  Further, according to the mobile communication system 4 according to the fourth embodiment, when the display control unit 155 of the receiving terminal 10b does not display the callback request icon 12a on the display unit 12, the notification is sent from the calling terminal 10a. A non-callback request icon 12b corresponding to the non-callback request is displayed on the display unit 12. For this reason, it is more effective that the user who cannot respond to the incoming call of the incoming terminal 10b can explicitly recognize that the callback to the outgoing terminal 10a is unnecessary, and makes an unnecessary callback. Can be prevented.

[Modification 1]
Next, the mobile communication system 5 according to the first modification of the first to fourth embodiments of the present invention will be described focusing on differences from the mobile communication system 1 according to the first embodiment.

  In the mobile communication system 5 according to the first modification, the receiving terminal 10b notifies the receiving terminal 10b of a callback request including a refusal time for refusing the callback from the receiving terminal 10b, so that the receiving terminal 10b is within the refusal time. Prevent making a callback to.

  Specifically, the setting unit 152 of the transmitting terminal 10a sets a refusal time during which a callback from the receiving terminal 10b is rejected based on the operation of the operation unit 14 by the user. Further, the notification unit 153 notifies the receiving terminal 10b of a callback request including the callback rejection time set by the setting unit 152.

  The network side device 21 acquires the callback request from the calling terminal 10a, and corrects the rejection time included in the callback request according to the time difference between the area where the calling terminal 10a is located and the area where the receiving terminal 10b is located. To do. The network side device 21 notifies the call-in terminal 10b of a callback request including a correction rejection time that is a rejection time corrected according to the time difference.

  The acquisition unit 154 of the receiving terminal 10b acquires the callback request notified from the network side device 21. In addition, the acquisition unit 154 sets the correction rejection time included in the acquired callback request as the callback rejection time for the calling terminal 10a. Further, as illustrated in FIG. 14, the acquisition unit 154 stores the identification information of the transmission terminal 10 a, the correction rejection time, and the rejection request status in association with each other based on the acquired callback request. Here, the rejection request status indicates whether or not the current time is within the callback correction rejection time, and if the current time is within the correction rejection time, it is “requesting” and the current time is corrected. If it is outside the rejection time, “no request” is set.

  The calling / receiving unit 151 of the receiving terminal 10b rejects the callback to the calling terminal 10a within the correction rejection time. The display control unit 155 of the incoming terminal 10b causes the display unit 12 to display a callback rejection screen (see FIG. 17B described later) indicating that the outgoing call to the outgoing terminal 10a has been rejected because the correction rejection time has elapsed.

  FIG. 15 is a sequence diagram showing a mobile communication method in the mobile communication system according to the first modification of the present invention. In this sequence diagram, it is assumed that the receiving terminal 10b has not been notified of a callback request from other transmitting terminals other than the transmitting terminal 10a.

  As illustrated in FIG. 15, the setting unit 152 of the transmission terminal 10 a sets a refusal time for refusing the callback from the receiving terminal 10 b based on the operation of the operation unit 14 by the user (step S <b> 601). For example, as shown in FIGS. 16A and 16B, the setting unit 152 sets “1:00 to 6:00” as the rejection time.

  The outgoing / incoming part 151 of the outgoing terminal 10a makes outgoing calls to the incoming terminal 10b based on the operation of the operation part 14 by the user. Further, the notification unit 153 of the transmission terminal 10a notifies the network side device 21 of a callback request including the rejection time set in step S601 to the reception terminal 10b (step S602).

  The network side device 21 performs an incoming call to the receiving terminal 10b in response to a call from the calling terminal 10a (step S603).

  The network side device 21 corrects the rejection time included in the callback request according to the time difference between the area where the transmitting terminal 10a is located and the area where the receiving terminal 10b is located (step S604). For example, the network side device 21 corrects the rejection time “1:00 to 6:00” to the correction rejection time “11:00 to 16:00”.

  The network side device 21 notifies the incoming call terminal 10b of a callback request including the corrected refusal time which is the refusal time corrected in step S604 (step S605).

  The acquisition unit 154 of the receiving terminal 10b acquires a callback request including the correction rejection time, and associates the identification information of the transmission terminal 10a with the correction rejection time and the rejection request status in the storage unit 13 as shown in FIG. Store (step S606).

  In response to the callback request acquired by the acquisition unit 154, the display control unit 155 of the receiving terminal 10b displays a callback request icon 12a (for example, FIG. 6A) on the display unit 12 (step S607). When the callback request icon 12a is selected by the operation of the operation unit 14 by the user, the display control unit 155 displays a rejection time notification screen indicating the correction rejection time to the user as shown in FIG. It is displayed on the display unit 12. If the user performs a call operation for instructing a callback within the correction refusal time, the calling / receiving unit 151 rejects the callback, and the display control unit 155 displays the call back as shown in FIG. Then, a callback rejection screen for rejecting the callback is displayed on the display unit 12.

  According to the mobile communication system 5 according to the modification example 1, the callback time notified from the calling terminal 10a includes the refusal time for refusing the callback from the receiving terminal 10b. For this reason, it is possible to prevent the user of the receiving terminal 10b who has not been able to respond to the incoming call from the transmitting terminal 10a from making a callback at a time not desired by the user of the transmitting terminal 10a.

  Also, according to the mobile communication system 5 according to the first modification, the network side device 21 determines the rejection time included in the callback request from the transmission terminal 10a as the coverage area of the transmission terminal 10a and the coverage area of the reception terminal 10b. Correct according to the time difference from the area. For this reason, even if there is a time difference between the area where the calling terminal 10a is located and the area where the receiving terminal 10b is located, the user of the receiving terminal 10b can be called appropriately at a time when the user of the calling terminal 10a does not want to The back can be prevented.

[Modification 2]
Next, the mobile communication system 6 according to the second modification of the first to fourth embodiments of the present invention will be described focusing on differences from the mobile communication system 1 according to the first embodiment.

  In the mobile communication system 6 according to the modified example 2, the network side device 21 determines whether or not the receiving terminal 10b is a terminal corresponding to the callback request, and based on the determination result, the callback request from the calling terminal 10a. To refuse.

  Specifically, the network side device 21 manages whether the receiving terminal 10b is a terminal corresponding to a callback request or a non-compatible terminal. When the network side device 21 acquires a callback request from the calling terminal 10a to the receiving terminal 10b, the network side device 21 determines whether or not the receiving terminal 10b is a terminal corresponding to the callback request. When the receiving terminal 10b is a compatible terminal, as described above, the network side device 21 transfers a callback request to the receiving terminal 10b. On the other hand, when the receiving terminal 10b is not a compatible terminal, the network side device 21 notifies the calling terminal 10a of a callback request disapproval notification indicating that the receiving terminal 10b is a non-compatible terminal for the callback request.

  FIG. 18 is a sequence diagram showing a mobile communication method in the mobile communication system 6 according to the second modification of the present invention. Note that steps S701 to S702 in FIG. 18 are the same as steps S101 to S102 in FIG.

  As shown in FIG. 18, the network side device 21 determines whether or not the receiving terminal 10b is a terminal corresponding to the callback request in response to the callback request from the transmitting terminal 10a (step S703).

  If the receiving terminal 10b is not a compatible terminal, the network side device 21 notifies the calling terminal 10a of a callback request disapproval notification indicating that the receiving terminal 10b is a non-compatible terminal for the callback request (step S704). ).

  The display control unit 155 of the calling terminal 10a displays a screen indicating that the callback request cannot be notified because the receiving terminal 10b is not a terminal that supports the callback request in response to the callback request notifying notification from the network side device 21. It is displayed on the display unit 12 (step S705).

  According to the mobile communication system 6 according to the modified example 2, the originating terminal 10a can detect that the terminating terminal 10b is not a terminal that supports the callback request based on the notification that the callback request is not received from the network side device 21. . For this reason, the user of the transmission terminal 10a can easily deal with contact with the user of the reception terminal 10b by using other means such as mail.

[Other changes]
When the receiving terminal 10b acquires the callback request including the callback request, the callback release request, the non-callback request, and the correction rejection time notified from the same transmitting terminal 10a, the receiving terminal 10b receives the latest notification. Based on this, updating of the storage unit 13 and display control of the display unit 12 may be performed. In addition, the above-described first to fourth embodiments and the mobile communication system according to the first or second modification can be used in combination.
