发明名称 MOBILE TERMINAL PERFORMING INFRARED COMMUNICATION WITH LOW POWER
摘要 A mobile communication terminal performing infrared communication with low power is provided to enable a control unit to generate a control signal for controlling the intensity of power applied to an IrDA module on the basis of a calculated distance, thereby saving the power of the mobile communication terminal necessary for the infrared communication. A mobile communication terminal comprises the followings: a calculating unit(14) which calculates connection setup time between the primary station and the mobile communication terminal on the basis of the number and contents of frames, transceived between the primary station and an IrDA(Infrared Data Association) module(12), and calculates a distance between the primary station and the mobile communication terminal on the basis of the calculated connection time; a control unit(16) which generates a control signal for controlling the intensity of power applied to the IrDA module(12) on the basis of the calculated distance; and a power supply unit(18) which supplies power corresponding to the control signal to the IrDA module(12).
