Abstract

When electronic mail transmitting operation is performed, it is checked whether the standby mode is the digital mode. If the standby mode is not the digital mode, processing for changing the standby mode from the analog mode to the digital mode is executed. When the standby mode is changed to the digital mode, the electronic mail is transmitted through a digital channel. If the standby mode cannot be changed to the digital mode, the transmission electronic mail is stored in a memory, and message hold transmission control is executed afterward.

Claims

1. A mobile communication terminal capable of communicating with a base station based on one of first and second communication modes, comprising:

selecting means for selecting one of the first and second communication modes;

detecting means for detecting a mail communication request of communicating with an electronic mail;

determining means for, when the mail communication request is detected by said detecting means, determining whether the selected communication mode is the first communication mode capable of communicating the electronic mail or the second communication mode incapable of communicating the electronic mail; and

means for, when said determining means is determines that the selected communication mode is the second communication mode, making an attempt to change of the selected second communication mode to the first communication mode.

2. A mobile communication terminal capable of communicating with a base station based on one of first and second communication modes, comprising:

selecting means for selecting one of the first and second communication modes;

detecting means for detecting a mail communication request of communicating with an electronic mail;

determining means for, when the mail communication request is detected by said detecting means, determining whether the selected communication mode is the first communication mode capable of communicating the electronic mail or the second communication mode incapable of communicating the electronic mail; and

control means for, when said determining means is determines that the selected communication mode is the second communication mode, changing the selected communication mode from the second communication mode to the first communication mode.

3. The terminal according to claim 2, further comprising:

setting means for selectively setting a first changing mode of validating a change of the communication mode made by said control means and a second changing mode of invalidating the change of the communication mode;

means for, when said setting means sets the first mode, causing said control means to change the communication mode; and

means for, when said setting means sets the second mode, inhibiting said control means to change the communication mode.

4. The terminal according to claim 2, further comprising:

means for determining whether the selected communication mode is changed to the first communication mode; and

means for, when the selected communication mode is changed to the first communication mode, notifying a user of said mobile communication terminal of the changing to the first communication mode.

5. A terminal according to claim 2, further comprising:

means for determining whether the selected communication mode is changed to the first communication mode; and

means for, when the selected communication mode is not changed to the first communication mode, notifying a user of said mobile communication terminal of the not changing to the first communication mode.

6. The terminal according to claim 2, further comprising:

means for determining whether the selected communication mode is changed to the first communication mode; and

means for, when the selected communication mode is not changed to the first communication mode, causing said control means to perform processing for changing the selected communication mode to the first communication mode again.

7. The terminal according to claim 2, further comprising:

means for determining whether the selected communication mode is changed to the first communication mode; and

storage means for, when the selected communication mode is not changed to the first communication mode, storing the electronic mail.

8. The terminal according to claim 7, wherein said storage means comprises:

means for selectively setting a first storage mode of validating storage of the electronic mail and a second storage mode of invalidating the storage of the electronic mail; and

means for, when the first storage mode is set, storing the electronic mail.

9. The terminal according to claim 7 or 8, wherein said storage means comprises means for, when the electronic mail is stored, notifying a user of said mobile communication terminal of the storing the electronic mail.

10. The terminal according to claim 7, further comprising:

means for determining whether the selected communication mode is changed to the first communication mode while the electronic mail is stored; and

transmission control means for, when the selected communication mode is changed to the first communication mode while the electronic mail is stored, reading out the stored electronic mail and transmit the read out electronic mail.

11. The terminal according to claim 10, further comprising:

means for determining whether transmission of the stored electronic mail is completed; and

means for, when transmission of the stored electronic mail is completed, notifying a user of said mobile communication terminal of the transmission completion.

14. The terminal according to claim 13, further comprising:

a second determining section configured to determine whether the selected communication mode is changed to the first communication mode; and

a storage section configured to store the electronic mail, when the selected set communication mode is not changed to the first communication mode.

15. The terminal according to claim 14, further comprising:

a third determining section configured to determine whether the selected communication mode is changed to the first communication mode while the electronic mail is stored; and

a transmission circuit configured to read out the stored electronic mail and transmit the read out electronic mail, when the selected communication mode is changed to the first communication mode.

12. A mobile communication terminal capable of communicating with a base station based on one of first and second communication modes, comprising:

a selecting section configured to select one of the first and second communication modes;

a detecting section configured to detect a mail communication request of communicating with an electronic mail;

a determining section configured to determine whether the selected communication mode is the first communication mode capable of communicating the electronic mail or the second communication mode incapable of communicating the electronic mail, when the mail communication request is detected by said detecting section; and

control section configured to make an attempt to changing of the selected communication mode, when said determining section is determines that the selected communication mode is the second communication mode.

13. A mobile communication terminal capable of communicating with a base station based on one of first and second communication modes, comprising:

a selecting section configured to select one of the first and second communication modes;

a detecting section configured to detect a mail communication request of communicating with an electronic mail;

a first determining section configured to determine whether the selected communication mode is the first communication mode capable of communicating the electronic mail or the second communication mode incapable of communicating the electronic mail, when the mail communication request is detected by said detecting section; and

control section configured to change the selected communication mode from the second communication mode to the first communication mode, when said first determining section is determines that the selected communication mode is the second communication mode.
