METHOD FOR OPERATING DUAL MODE MOBILE DEVICE SIMULTANEOUSLY AND SAVING POWER BY CONTROLLING MODULATION SCHEME.

摘要

PURPOSE: A method for simultaneous communication and efficient power use through mutual modulation control in a dual mode wireless mobile communication terminal is provided to use mobile communication methods at the same time without an additional power supply device, thereby improving usability of the terminal. CONSTITUTION: An interface device notifies a currently used modulation method to the outside. A power consumption measurement device centralizes the interface device. The power consumption measurement device increases or decreases power capacity used of whole power capacity according to data inputted from each device. An observing device measures the amount of currently used power. The priority among plural mobile communication modes is determined. A transmission priority is assigned among respective modes according to importance of the plural mobile communication modes.
