Abstract

A communication apparatus having a main battery for performing main operations of the communication apparatus so as to connect or remove from the device freely. The communication apparatus includes a clock unit and a control unit. The clock unit configured to count a current time by using power supplied by the main battery, and configured to acquire the current time from a base station based on the main battery was connected after the main battery was removed the communication apparatus. And the control unit configured to control so as to set the current time acquired by the clock unit as the current time counted.

Claims

1. A communication apparatus having a main battery for performing main operations of the communication apparatus so as to connect or remove from the device freely, comprising:

a clock unit configured to count a current time by using power supplied by the main battery, and configured to acquire the current time from a base station based on the main battery was connected after the main battery was removed the communication apparatus, and

a control unit configured to control so as to set the current time acquired by the clock unit as the current time counted.

2. The communication apparatus according to claim 1, wherein

the clock unit is not capable of count the current time if the battery is not connected to the communication apparatus.

3. The communication apparatus according to claim 2, wherein

the clock unit configured to count the current time and to acquire the current time, even if a status of a power supply is ON or OFF and if the main battery is connected to the communication apparatus, and

the control unit configured to control to set even if the status of the power supply is ON or OFF.

4. The communication apparatus according to claim 1, further comprising:

a storage unit configured to store a schedule information, the schedule information including a designated time information of the schedule, a content information indicating a content displayed at the designated time of schedule, and an execution status information indicating whether notification has been done or not, and wherein

the control unit controls to, if the control unit sets the current time and if the control unit detects not to inform the content information despite passing the designated time, inform the content information passing the designated time.

5. The communication apparatus according to claim 2, further comprising:

a storage unit configured to store a schedule information, the schedule information including a designated time information of the schedule, a content information indicating a content displayed at the designated time of schedule, and an execution status information indicating whether notification has been done or not, and wherein

the control unit controls to, if the control unit sets the current time and if the control unit detects not to inform the content information despite passing the designated time, inform the content information corresponding to the designated time passed.

6. The communication apparatus according to claim 4, wherein,

the control unit informs the content information with alarm.

7. The communication apparatus according to claim 5, wherein,

the control unit informs the content information with alarm.

8. A communication apparatus having a rechargeable main battery for performing main operations of the communication apparatus so as to connect or remove from the device freely, comprising:

a clock unit configured to count a current time by using power supplied by the rechargeable main battery, and configured to acquire the current time from a base station based on started to recharge the rechargeable main battery after the communication apparatus could not keep a power on status according not to supply a power from the rechargeable main battery, and

a control unit configured to control so as to set the current time acquired by the clock unit as the current time counted.

9. The communication apparatus according to claim 8, wherein

the clock unit is not capable of count the current time if the battery is not connected to the communication apparatus.

10. The communication apparatus according to claim 9, wherein

the clock unit configured to count the current time and to acquire the current time, even if a status of a power supply is ON or OFF and if rechargeable main battery is connected to the communication apparatus, and
