Abstract

A power consumption control apparatus and a method thereof in the PDA phone comprise: transiting the PDA phone from an idle mode to a sleep mode automatically after a certain amount of time or by user'"'"'s input signal; transiting the PDA phone from a called mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal; transiting the PDA phone from a calling mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal; and transiting the PDA phone from an in-call mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal, so that the power consumption control apparatus and the method thereof in a personal digital assistant (PDA) phone in accordance with the present invention can reduce power consumption of the PDA phone by transiting the PDA phone from a called mode, an in-called mode and a calling mode to a sleep mode, and cope with the circumstances which may occur in every state of the PDA phone.

Claims

1. A power consumption control apparatus in a personal digital assistant (PDA) phone, performing the steps of:

transiting the PDA phone from an idle mode to a sleep mode automatically after a certain amount of time or by user'"'"'s input signal;

transiting the PDA phone from a called mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal;

transiting the PDA phone from a calling mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal; and

transiting the PDA phone from an in-call mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal.

2. The apparatus of claim 1, further performing:

transiting the PDA phone from the sleep mode, which is transited from the idle mode, to the called mode when a call signal is received.

3. The apparatus of claim 1, further performing:

transiting the PDA phone from the sleep mode, which is transited from the called mode, to the in-call mode when the received call signal is accepted.

4. The apparatus of claim 1, further performing:

transiting the PDA phone from the sleep mode, which is transited from the calling mode, to the in-call mode when the sent call signal is accepted.

5. The apparatus of claim 1, further performing:

transiting the PDA phone from the sleep mode, which is transited from the in-call mode, to the idle mode when a phone call is terminated.

6. The apparatus of claim 1, further performing:

transiting the PDA phone from the sleep mode, which is transited from the called mode, to the called mode when a user sends an input signal.

7. The apparatus of claim 1, further performing:

transiting the PDA phone from the sleep mode, which is transited from the calling mode, to the calling mode when the user sends an input signal.

8. The apparatus of claim 1, further performing:

transiting the PDA phone from the sleep mode, which is transited from the in-call mode, to the in-call mode when the user sends an input signal.

9. A power consumption control method in a personal digital assistant (PDA) phone, comprising:

transiting the PDA phone from an idle mode to a sleep mode automatically after a certain amount of time or by user'"'"'s input signal;

transiting the PDA phone from a called mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal;

transiting the PDA phone from a calling mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal; and

transiting the PDA phone from an in-call mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal.

10. The method of claim 9, further comprising:

transiting the PDA phone from the sleep mode, which is transited from the idle mode, to the called mode when a call signal is received.

11. The method of claim 9, further comprising:

transiting the PDA phone from the sleep mode, which is transited from the called mode, to the in-call mode when the received call signal is accepted.

12. The method of claim 9, further comprising:

transiting the PDA phone from the sleep mode, which is transited from the calling mode, to the in-call mode when the sent call signal is accepted.

13. The method of claim 9, further comprising:

transiting the PDA phone from the sleep mode, which is transited from the in-call mode, to the idle mode when a phone call is terminated.

14. The method of claim 9, further comprising:

transiting the PDA phone from the sleep mode, which is transited from the called mode, to the called mode when a user sends an input signal.

15. The method of claim 9, further comprising:

transiting the PDA phone from the sleep mode, which is transited from the calling mode, to the calling mode when the user sends an input signal.

16. The method of claim 9, further comprising:

transiting the PDA phone from the sleep mode, which is transited from the in-call mode, to the in-call mode when the user sends an input signal.

17. A power consumption control method in a PDA phone, comprising:

transiting the PDA phone from a called mode to a sleep mode automatically after a certain amount of time or by user'"'"'s input signal.

18. A power consumption control method in a PDA phone, comprising:

transiting the PDA phone from a calling mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal.

19. A power consumption control method in a PDA phone, comprising:

transiting the PDA phone from an in-call mode to the sleep mode automatically after a certain amount of time or by user'"'"'s input signal.
