Title
(EN) Communication link switching method and device, terminal and computer readable storage medium
(ZH) 通信链路的切换方法、装置、终端和计算机可读存储介质
Abstract
(EN)
The embodiment of the invention discloses a communication link switching method and device, a terminal and a computer readable storage medium. The method comprises the following steps: detecting the signal intensity of a first network signal and the signal intensity of a second network signal in real time; when the signal intensity of the first network signal and/or the signal intensity of the second network signal is greater than or equal to a first threshold, selecting the first communication link and/or the second communication link to transmit data according to a preset transmission strategy; and when the signal intensity of the first network signal and the signal intensity of the second network signal are smaller than a second threshold, selecting the third communication link to transmit data. Through the method, the communication link can be automatically switched according to the signal intensity of different network signals, the stability of the communication system is improved, and the robustness of the terminal equipment in the communication process is improved.
