Method for controlling human body radiation absorptivity and mobile terminal

The embodiment of the invention provides a method for controlling the human body radiation absorptivity and a mobile terminal, and the method comprises the steps: judging whether the mobile terminal is in a human body radiation working state or not, and reducing the signal intensity through a signal directivity weakening device when the mobile terminal is in the human body radiation working state.By means of the method, it is ensured that only when the mobile terminal is in the human body radiation working state, the signal directivity weakening device can reflect or weaken signals of the frequency band corresponding to the antenna, the intensity of wireless signal radiation emitted by the antenna in the human body direction is reduced, and then the effect of reducing SAR is achieved. 本发明实施例提供了一种控制人体辐射吸收率的方法和移动终端，其中，所述方法包括：判断移动终端是否处于人体辐射工作状态，当移动终端处于人体辐射工作状态时，通过信号方向性衰弱装置降低信号强度。通过上述方法，从而确保移动终端只有在处于人体辐射工作状态时，信号方向性衰弱装置才会起到对天线对应频段的信号产生反射或衰弱作用，降低天线发射的无线信号辐射在人体方向的强度，进而起到了降低SAR的作用。
