Problems solved by technology

Its shortcoming is that it does not take into account the latest development trend of current mobile terminals. Now more and more mobile terminals adopt all-metal body, and at the same time, multi-antenna is designed to solve the situation of users holding dead, and it supports multi-antenna switching technology. The power consumption of the mobile terminal is different in different scenarios, and the second method cannot be realized.

Embodiment 1

[0041] figure 1 It is a schematic flowchart of the first embodiment of a method for adjusting radiation in the present invention. The method for adjusting radiation is applied to a mobile terminal, and the method flow shown in this embodiment includes the following steps:

[0042] Step S14, in response to the occurrence of a radiation event, determine the radio frequency transmitting antenna supported by the mobile terminal according to the radiation event in the frequency band where the mobile terminal is currently working.

[0043] Wherein, the radiation event is an event that may generate radiation to a human body during use of the mobile terminal. For example, "response to the occurrence of a radiation event" refers to the occurrence of the scene in which the WIFI hotspot is turned on, the scene in which the mobile terminal is close to the user's head to talk, or the scene in which the mobile terminal is turned on under the WIFI hotspot to talk close to the user's head. ...

Abstract

The invention provides a method for adjusting radiation. The method for adjusting radiation is applied to a mobile terminal, and the method comprises the following steps: making response to the occurrence of a radiation event, and determining a radio frequency transmitting antenna supported by the mobile terminal on a frequency band where the mobile terminal is working at present according to the radiation event; obtaining a preset power value corresponding to the radio frequency transmitting power of the determined antenna; and controlling the determined antenna to transmit power according to the obtained preset power value. The invention further provides an apparatus for adjusting radiation. Different antennas are controlled to transmit power at a power value not exceeding the maximum limited power value according to the radiation event of the mobile terminal, and the human body radiation SAR of the mobile terminal designed by multiple antennas is dynamically adjusted to reduce the human body radiation.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for adjusting radiation. Background technique [0002] There are two existing methods for reducing human body radiation SAR ("specific absorption ratio", electromagnetic wave absorption ratio) by mobile terminals. The first method: by pre-judging the harmful radiation direction of electromagnetic waves in the design stage of the mobile terminal, adding absorbing materials or scattering electromagnetic wave materials at the corresponding positions, so as to achieve the purpose of reducing the SAR radiation of the human body. The disadvantage is that the cost of the mobile terminal is increased, and at the same time, the difficulty of structural design is increased under the trend that the structure of the mobile terminal becomes more and more complex and thinner. [0003] The second method: Dynamically adjust the transmission power from the software...
