Method and apparatus that annunciates when a mobile telephone is out of a service area
View Patent ↗The mobile telephone includes (a) a detector which transmits a detection signal when the detector detects that the mobile telephone is in a stand-by mode where the mobile telephone waits receiving a radio signal from a base station, and that the mobile telephone is located out of a service area, (b) a timer which starts measuring a period of time in which the mobile telephone keeps located out of the service area, on receipt of the detection signal, and (c) at least one annunciator which makes at least one of sounds and vibration. The detector annunciates that the mobile telephone keeps located out of the service area for a predetermined first period of time, when the mobile telephone is in a stand-by mode, to a user through the annunciator, when a period of time measured by the timer reaches the predetermined first period of time.
1. A method of operating a mobile telephone, comprising:
annunciating through at least one of sounds and vibration when said mobile telephone has been out of a service area for a predetermined first period of time and is in a stand-by mode;
setting said predetermined first period of time while said telephone is operating;
interrupting a supply of power to the mobile telephone at a time that the annunciating has finished; and
setting a second period of time regarding a duration of said annunciating.
2. The method as set forth in claim 1 , further comprising returning to said stand-by mode.
3. The method as set forth in claim 1 , further comprising:
returning to said stand-by mode, if said mobile telephone moves into said service area before said predetermined first period of time has passed after said mobile telephone has moved out of said service area.
4. The method as set forth in claim 1 , further comprising selecting at least one of a speaker constituting a hand-set, a sounder making a single or mixed sound, and a vibrator which vibrates said mobile telephone, for said annunciation.
5. The method as set forth in claim 1 , further comprising ceasing said annunciating in response to actuation of a predetermined key.
6. The method of claim 1 , wherein said mobile telephone waits to receive a radio signal from a base station during said stand-by mode.
7. A method of operating a mobile telephone, comprising:
setting a predetermined first period of time while said telephone is operating;
annunciating through at least one of sounds and vibration when said mobile telephone has been out of a service area for said predetermined first period of time and is in a stand-by mode;
turning off a power supply of said mobile telephone at the time that said annunciating finishes; and
setting a second period of time regarding a duration of said annunciating.
8. A method of operating a mobile telephone, comprising:
setting a predetermined first period of time while said telephone is operating;
annunciating through at least one of sounds and vibration when said mobile telephone has been out of a service area for said predetermined first period of time and is in a stand-by mode;
ceasing said annunciation and returning to said stand by mode if said mobile telephone moves into said service area during said annunciation; and
interrupting a power supply to the mobile telephone at the time that said annunciating finishes and said mobile telephone remains out of said service area; and
setting a second period of time regarding a duration of said annunciating.
9. A method of operating a mobile telephone, comprising:
annunciating through at least one of sounds and vibration when said mobile telephone has been out of service area for a predetermined first period of time and is in a stand-by mode;
setting a second period of time regarding a duration of said annunciating is carried out; and
interrupting a power supply to the mobile telephone at the time that said annunciating finishes.
10. A mobile telephone comprising:
a detector that transmits a detection signal when said detector detects that said mobile telephone is in a stand-by mode and is located out of a service area;
a timer that starts measuring a period of time in response to said detection signal; and
at least one annunciator that makes at least one of sounds and vibration, when the period of time measured by said timer reaches a predetermined first period of time;
an interface that sets said predetermined first period of time while said telephone is operating; and
a power supply that interrupts power to the mobile telephone at a time that said at least one annunciator finishes annunciating, and wherein a second period of time regarding a duration of said annunciation can be determined by a user through said interface while said telephone is operating.
11. The mobile telephone as set forth in claim 10 , wherein said detector returns said mobile telephone to said stand-by mode after said annunciator has finished annunciating.
12. The mobile telephone as set forth in claim 10 , wherein said detector returns said mobile telephone to said stand-by mode, if said mobile telephone moves into said service area before said predetermined first period of time has passed after said mobile telephone has moved out of said service area.
13. The mobile telephone as set forth in claim 10 , further comprising:
a speaker constituting a hand-set;
a sounder making a single or mixed sound; and
a vibrator that vibrates said mobile telephone, and
wherein a user can select at least one of said speaker, said sounder and said vibrator as said annunciator through said interface.
14. The mobile telephone as set forth in claim 10 , wherein a user can compulsively cease said annunciating through said interface, while said annunciating is being carried out.
15. The mobile telephone of claim 10 , wherein said mobile telephone waits to receive a radio signal from a base station during said stand-by mode.
16. A mobile telephone comprising:
a detector that transmits a detection signal when said detector detects that said mobile telephone is in a stand-by mode and is located out of a service area;
a timer that starts measuring a period of time in response to said detection signal;
an annunciator that makes at least one of sounds and vibration when the period of time measured by said timer reaches a predetermined first period of time, wherein said detector interrupts a power supply to said mobile telephone, at a time that said annunciator has finished annunciating; and
an interface that sets said predetermined first period of time while said telephone is operating, and wherein a second period of time regarding a duration of said annunciation can be determined by a user through said interface while said telephone is operating.
17. A mobile telephone, comprising:
a detector that transmits a detection signal when said detector detects that said mobile telephone is in a stand-by mode and is located outside of a service area;
a timer that starts measuring a period of time in response to said detection signal;
an annunciator that makes at least one of sounds and vibration when the period of time measured by said timer reaches a predetermined first period of time, wherein said detector ceases annunciation and returns said mobile telephone to said stand-by mode, if said mobile telephone moves into said service area while said annunciation is being carried out;
an interface that sets said predetermined first period of time while said telephone is operating; and
a power supply that interrupts power to the mobile telephone at a time that said annunciator finishes annunciating while said mobile telephone is located outside of said service area, and wherein a second period of time regarding a duration of said annunciation can be determined by a user through said interface while said telephone is operating.
