Problems solved by technology

The above processing method is generally used in tablet computers. At present, as the size of mobile phones is getting closer and closer to that of tablet computers, it will sooner or later be used in mobile phones. The advantage is that the reduction is flexible and controllable. The disadvantage is that the sensitivity of the SAR antenna to sense the approach of the human body is reduced. (Sensing range) restricts the sensitivity of mobile terminal radiation power changes. What happens is that the human body is not close to the terminal sensor and the sensor has started to work, or the human body has been close to the terminal sensor and has not started to work, and misjudgment occurs

Embodiment Construction

[0024] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0025] In the prior art, commonly used SAR reduction methods cannot determine the exact position of the human body approaching the mobile terminal, and cannot use the optimal working mode of the sensor antenna to sense the human body approaching, and the sensing range is often too close or too small. Misjudgment occurs, the radiation power of the mobile terminal cannot be controlled in time, and the human body cannot be protected in...

Abstract

Provided are a method and device for controlling transmitting power. According to the method, when it is detected that a target object approaches a mobile terminal, a position, which the target object approaches, on the mobile terminal is determined, and an optimal sensing area for a Specific Absorption Rate (SAR) reducing antenna of the mobile terminal to sense a movement of the target object is selected according to the position; movement information of the target object is acquired by sensing the movement of the target object in the optimal sensing area by the reduced SAR antenna, and the transmitting power of the mobile terminal is controlled according to the movement information. The technical solution can ensure at all time that the position of the approaching human body is sensed by the reduced SAR antenna in an optimal working mode, thereby improving the sensing distance and range of the reduced SAR antenna, namely, improving the sensitivity of the reduced SAR antenna.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a transmission power control method and device. Background technique [0002] Mobile terminals have become an indispensable communication and entertainment tool in current life and work, and the trend of mobile terminals is developing in the direction of large screen and intelligentization. Currently, large-screen smartphones and tablet computers are more and more widely used, and there are signs of further encroachment on the traditional personal computer (Personal Computer, PC for short) market. Therefore, it is needless to say that various equipment manufacturers attach importance to and invest in mobile terminals. [0003] But on the other hand, the impact of mobile terminal radiation on the human body has also attracted the attention of various countries, organizations and consumers. At present, in the certification of mobile terminals, especially tablet products, the e...
