Patent attributes
Embodiments of this application provide a network switching method that comprises connecting, by a terminal device, to a first network, where a first application on the terminal device is connected to the first network, switching, by the terminal device, from the first network to a second network, and retaining a connection between the first application and the first network. The method further comprises receiving, by the terminal device, a network connection request from a second application on the terminal device, and connecting, by the terminal device, the second application to the second network. The network switching method does not cause interruption to the connection between the first application and the first network and to the ongoing data transmission between the first application and the first network, thereby improving data transmission performance.
