Network switching method and device

The invention discloses a network switching method and device, and belongs to the technical field of communication. The problem that the quality is poor when the electronic equipment carries out voiceservice can be solved. The method comprises the steps that under the condition that at least two wireless fidelity Wi-Fi networks are connected at the same time and wireless voice VoWiFi service is performed through a first Wi-Fi network, at least two first signal parameters of the electronic equipment are acquired, and the at least two Wi-Fi networks comprise the first Wi-Fi network; and when the first signal parameter of the first Wi-Fi network is less than or equal to a first preset threshold and the first signal parameter of the second Wi-Fi network is greater than or equal to a second preset threshold, the current Wi-Fi network of the electronic equipment which performs VoWiFi service is controlled to switch from a first Wi-Fi network to a second Wi-Fi network, wherein the second Wi-Fi network is any Wi-Fi n
