Embodiment 1

[0047] In the first embodiment, the transmission power adjustment module (203) reduces the signal transmission power of the mobile terminal when the distance between the human body and the mobile terminal is within a preset distance range; When the distance range is exceeded, the signal transmission power of the mobile terminal is increased.

Embodiment 2

[0048] In the second embodiment, the transmission power adjustment module (203) reduces the signal transmission power of the mobile terminal when the bottom side of the current position of the mobile terminal is adjacent to the terminal antenna; When the side is not adjacent to the terminal antenna, the signal transmission power of the mobile terminal is increased.

Embodiment 3

[0049] In Embodiment 3, when the distance between the human body and the mobile terminal is within a preset distance range and the bottom side of the current position of the mobile terminal is learned through the gravity sensor is the adjacent side of the terminal antenna, the transmission power adjustment module (203) reduces the The signal transmission power of the mobile terminal; when the distance between the human body and the mobile terminal is not within the preset distance range or when the gravity sensor knows that the bottom side of the current position of the mobile terminal is not the adjacent side of the terminal antenna, increase the mobile The signal transmission power of the terminal.

[0050] Wherein, the state monitoring module (202) can determine the screen display direction of the mobile terminal based on the data of the gravity sensor, so as to determine the bottom side of the current position of the mobile terminal.

[0051] The method for adjusting the e...

Abstract

The invention discloses a method for adjusting an electromagnetic wave energy absorption ratio based on a sensor and a mobile terminal. The mobile terminal adjusts signal transmitting power of the mobile terminal according to whether the distance which is acquired by a proximity sensor and between a human body and the mobile terminal is located in a preset distance range and/or whether a bottom side surface of the current position, acquired by a gravity sensor, of the mobile terminal is the adjacent side surface of a terminal antenna. The scheme disclosed by the invention controls the signal transmitting power of the mobile terminal according to data of the sensors, therefore, the electromagnetic wave energy absorption ratio is controlled, the problem that the human body is affected due to the fact that an SAR (specific absorption rate) value is out of limit in the prior art, and users of the mobile terminals are protected in real time.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a sensor-based method for adjusting an electromagnetic wave energy absorption ratio (Specific Absorption Rate, referred to as SAR) and a mobile terminal. Background technique [0002] Mobile terminals (eg, mobile phones, tablet computers) have become indispensable communication tools, but at the same time, the radiation of mobile terminals' transmission power to the human body has also been valued by various countries and organizations. [0003] SAR is usually called specific absorption rate, which refers to the absorption ratio of electromagnetic wave energy of mobile terminals, which is the electromagnetic power absorbed or consumed by human tissue per unit mass, and the unit is W / kg, or mW / mg. The SAR requirements under FCC certification are extremely high. For example, when the diagonal size of the tablet computer is greater than 8 inches, the other 5 surfaces except the LC...
