Abstract
A mobile device and its control method allow a system booting in an emergency mode to operate by redefining a reference cutoff voltage when the mobile device enters into the power-off state in a cutoff mode, wherein the mobile device can support an emergency call service through a minimum booting procedure although other non-essential functions have been curtailed.
Claims16
A method for a cutoff-based power control in a mobile device, the method comprising:
- detecting by a control unit a power-off interaction of the mobile device;
- if the power-off interaction is based on a cutoff mode, redefining a reference cutoff voltage;
- forcing the mobile device to enter into a power-off state;
- and
- controlling a system driving of the mobile device on the basis of the redefined reference cutoff voltage in the power-off state based on the cutoff mode.
2 more elements
A mobile device comprising:
- a power supply configured to receive and supply power;
- a memory unit configured to store a reference cutoff voltage providing an entry into a power-off state based on a cutoff mode;
- and
- a control unit configured to redefine the reference cutoff voltage when the mobile device enters into the power-off state based on the cutoff mode, and to control a system driving of the mobile device on the basis of the redefined reference cutoff voltage.
