APPARATUS AND METHOD FOR CONTROLLING ELECTRIC POWER OF BATTERY ACCORDING TO RECEIVED SIGNAL STRENGTH INDICATOR OF DUAL BAND DUAL MODE TERMINAL
First Claim
1. An apparatus for electric power management according to Received Signal Strength Indicator (RSSI) of a Dual Band Dual Mode (DBDM) terminal that provides a mobile communication service and a portable Internet service, the apparatus comprising:
- a mobile communication unit for transmitting/receiving a mobile communication signal;
a portable Internet unit for transmitting/receiving a portable Internet signal;
a battery measuring unit for measuring remaining battery capacity;
a power supply unit for supplying battery power to the mobile communication unit and portable Internet unit; and
a controller for deriving remaining run times of the mobile communication unit and portable internet unit using consumption current according to the RSSI of the mobile communication unit and the portable Internet unit when the remaining battery capacity of the battery measuring unit is less than a set value, and for controlling power supply of the power supply unit based on the derived remaining run times.
