Abstract

A mobile apparatus including: a wireless communication module that receives a signal transmitted via a base station; a display that displays character; an input module that inputs the character or operation data; a first operating mode in which electric power is supplied to the display; a second operating mode in which electric power is not supplied to the display; an information reception module that receives information received via the wireless communication module or power saving monitoring information; an input monitoring module that monitors an unoperated state; a display controller that switches the first operating mode to the second operating mode when the unoperated state is detected; and a power saving controller that reduces information reception frequency at the information reception module when the unoperated state is detected by the input monitoring module.

Claims

1. A mobile apparatus comprising:

a wireless communication module configured to receive a signal transmitted via a base station;

a display configured to display graphic or character;

an input module configured to input at least one of the graphic or character and operation data;

a first operating mode in which electric power is supplied to the display;

a second operating mode in which electric power is not supplied to the display;

an information reception module configured to receive at least one of information received via the wireless communication module and power saving monitoring information of the mobile apparatus;

an input monitoring module configured to monitor an unoperated state that includes a state where the input module is not operated;

a display controller configured to switch the first operating mode to the second operating mode when the unoperated state is detected by the input monitoring module; and

a power saving controller configured to reduce information reception frequency at the information reception module when the unoperated state is detected by the input monitoring module.

2. The mobile apparatus of claim 1, wherein the power saving controller is configured to reduce information reception frequency at the information reception module in accordance with the switching to the second operating mode.

3. The mobile apparatus of claim 2, wherein the power saving monitoring information includes at least one of:

reception processing information of a message given from a push application, information of a notice of electric field intensity change given from a voltage level monitoring module, and information of a notice of time given from a time monitoring module.

4. The mobile apparatus of claim 2, wherein:

the display controller is configured to switch the second operating mode back to the first operating mode when the unoperated state is not detected by the input monitoring module; and

the power saving controller is configured to increase the reduced information reception frequency to original frequency in accordance with the switching to the first operating mode.

5. The mobile apparatus of claim 4, wherein the power saving monitoring information includes at least one of:

reception processing information of a message given from a push application, information of a notice of electric field intensity change given from a voltage level monitoring module, and information of a notice of time given from a time monitoring module.

6. The mobile apparatus of claim 1, wherein, when the unoperated state is not detected by the input monitoring module:

the display controller is configured to switch the second operating mode back to the first operating mode; and

the power saving controller is configured to increase the reduced information reception frequency to original frequency.

7. The mobile apparatus of claim 6, wherein the power saving monitoring information includes at least one of:

reception processing information of a message given from a push application, information of a notice of electric field intensity change given from a voltage level monitoring module, and information of a notice of time given from a time monitoring module.

8. The mobile apparatus of claim 1, wherein the power saving monitoring information includes at least one of:

reception processing information of a message given from a push application, information of a notice of electric field intensity change given from a voltage level monitoring module, and information of a notice of time given from a time monitoring module.

9. A power saving control method in a mobile apparatus including:

a wireless communication module configured to receive a signal transmitted via a base station;

a display configured to display graphic or character;

an input module configured to input at least one of the graphic or character and operation data;

a first operating mode in which electric power is supplied to the display;

a second operating mode in which electric power is not supplied to the display, the power saving control method comprising;

monitoring an unoperated state that includes a state where the input module is not operated;

switching the first operating mode to the second operating mode when the unoperated state is detected; and

reducing frequency of reception of at least one of information received via the wireless communication module and power saving monitoring information of the mobile apparatus when the unoperated state is detected.

10. The power saving control method of claim 9, wherein the reducing step includes reducing frequency of reception of at least one of information received via the wireless communication module and power saving monitoring information of the mobile apparatus in accordance with the switching to the second operating mode.

11. The power saving control method of claim 10, further comprising:

switching the second operating mode back to the first operating mode when the unoperated state is not detected; and

increasing the reduced information reception frequency to original frequency in accordance with the switching to the first operating mode.

12. A power saving control method of claim 9, wherein, when the unoperated state is not detected:

switching the second operating mode back to the first operating mode; and

increasing the reduced information reception frequency to original frequency.

13. A non-transitory computer-readable medium containing software instructions for causing a mobile apparatus to perform a power saving control process, the mobile apparatus including:

a wireless communication module configured to receive a signal transmitted via a base station;

a display configured to display graphic or character;

an input module configured to input at least one of the graphic or character and operation data;

a first operating mode in which electric power is supplied to the display;

a second operating mode in which electric power is not supplied to the display, wherein the software instructions comprise;

monitoring an unoperated state that includes a state where the input module is not operated;

switching the first operating mode to the second operating mode when the unoperated state is detected; and

reducing frequency of reception of at least one of information received via the wireless communication module and power saving monitoring information of the mobile apparatus when the unoperated state is detected.

14. The non-transitory computer-readable medium of claim 13, wherein the reducing step includes reducing frequency of reception of at least one of information received via the wireless communication module and power saving monitoring information of the mobile apparatus in accordance with the switching to the second operating mode.

15. The non-transitory computer-readable medium of claim 14, wherein the software instructions further comprise:

switching the second operating mode back to the first operating mode when the unoperated state is not detected; and

increasing the reduced information reception frequency to original frequency in accordance with the switching to the first operating mode.

16. The non-transitory computer-readable medium of claim 13, wherein the software instructions further comprise switching the second operating mode back to the first operating mode and increasing the reduced information reception frequency to original frequency when the unoperated state is not detected.
