Problems solved by technology

The above method has the following problems: After the antenna is switched, it will work on the antenna with better performance, but at the same time it may cause the problem of an increase in the SAR (Specific Absorption Rate, electromagnetic wave absorption ratio or absorption ratio). The heat energy generated by electromagnetic waves is a measure of the impact on the human body, and the unit is W / Kg (watts / kg)
How to make a trade-off between the two indicators of signal quality and SAR value, the current general methods have not solved it

Abstract

The invention discloses an antenna switching method, device and equipment, and a computer readable storage medium, and belongs to the technical field of communication. The method comprises the steps of obtaining signal quality and an electromagnetic wave absorption ratio of two antennas; detecting the signal quality of the first antenna, the signal quality of the second antenna and a preset signalquality threshold; when the signal quality of the first antenna and the signal quality of the second antenna are both greater than a preset signal quality threshold, selecting the antenna with a smaller electromagnetic wave absorption ratio as a working antenna; when one of the signal quality of the first antenna and the signal quality of the second antenna is smaller than a preset signal qualitythreshold, selecting the antenna with higher signal quality as a working antenna; by detecting and comparing the current signal receiving quality of the two or more antennas with the SAR value, carrying out switching, so that the terminal works on the antenna with better signal quality and smaller SAR value, the harm to a human body is avoided, the received signal of the terminal is improved, anda user has better user experience.

Description

technical field [0001] This article relates to the field of communication technologies, and in particular to an antenna switching method, device, equipment, and computer-readable storage medium. Background technique [0002] With the development of the communication industry, the standards that mobile terminals need to support cover 2G, 3G, and 4G. In the 4G era, terminal antennas need to support more frequency bands and wider bandwidths. Business requirements such as CA and MIMO also put forward higher requirements for antennas. At the same time, the appearance of the terminal is becoming more and more important. Metal machines that meet the higher aesthetic requirements of users have also become popular, but at the same time, the antenna indicators will deteriorate and the work performance will decrease; on the other hand, people are becoming more and more concerned about their health. We always hope that electronic products will have the least impact on our health and saf...
