Patent ID: 8060152

Claim:
An apparatus for current control in a mobile terminal, the apparatus comprising: a first communication unit for providing communication with a first communication network; a second communication unit for providing communication with a second communication network having a lower priority order than that of the first communication network; a power supply unit for supplying current; a monitoring unit for measuring a total required current amount, detecting whether the total required current amount is greater than a limit threshold value, and controlling a current amount to be consumed in the second communication unit to be reduced through a hardware control path when the total required current amount is greater than the limit threshold value; a memory unit for storing a current distribution table with information about supply current amounts for respective components of the mobile terminal, the supply current amounts for the respective components corresponding to the total required current amount; and a power distribution unit for searching the supply current amounts using the current distribution table when detecting through the monitoring unit that the total required current amount is greater than the limit threshold value, and controlling the power supply unit to supply current to the respective components according to the searched supply current amounts, wherein the power distribution unit controls interruption of supplying current to some of the respective components that do not affect the communication function of the first communication unit according to the result of searching the current distribution table.
