Method for reducing SAR value of mobile terminal, storage medium and mobile terminal

Abstract

The invention discloses a method for reducing an SAR value of a mobile terminal, a storage medium and the mobile terminal. The method comprises the following steps: in a call process, detecting and comparing the signal strength of an upper antenna and a lower antenna of the mobile terminal in real time; and when it is detected that the signal strength of the upper antenna of the mobile terminal is greater than that of the lower antenna, switching the communication work of the mobile terminal to the upper antenna, and reducing the radio frequency transmitting power of the upper antenna. By adoption of the method disclosed by the invention, the communication work of the mobile terminal is always implemented by the antenna with greater signal strength, and when the upper antenna is switched to implement the communication work of the mobile terminal, the SAR value of the mobile terminal can be reduced by reducing the radio frequency transmitting power of the upper antenna.

Description

Technical field [0001] The invention relates to the field of mobile terminals, in particular to a method for reducing the SAR value of a mobile terminal, a storage medium and a mobile terminal. Background technique [0002] The current mobile terminal antenna design is becoming more and more complicated. Taking mobile phones as an example, in order to meet its communication performance, many mobile phone project designs will adopt the upper and lower antenna switching mechanism. That is to say, when the user holds the phone's lower antenna, the communication performance of the lower antenna will decrease. At this time, the communication should be switched to the upper antenna to meet the specifications of the antenna to transmit and receive signals. [0003] However, this antenna switching method will bring a problem, that is, when the user makes a call, the upper part of the mobile phone is close to the user's head. At this time, if the high frequency band in the mobile phone is e...

Problems solved by technology

[0005] In view of the deficiencies in the prior art above, the purpose of the present invention is to provide a method for reducing the SAR value of a mobile terminal, a storage medium, and a mobile terminal, aiming to solve the problem that the user's head is easily caused when the existing mobile terminal switches to the upper antenna for communication. The SAR value exceeds the standard, which endangers the health of users
