Abstract: A call switching method includes: when a first terminal device detects an input operation that is of initiating a call request to a second terminal device, or when a first terminal device receives a first call request that is initiated by a second terminal device by using a second-type communications network, detecting whether both the first terminal device and the second terminal device are in a first-type communications network; and when the first terminal device detects that both the first terminal device and the second terminal device are in the first-type communications network, initiating a second call request to the second terminal device by using the first-type communications network, or sending first prompt information to the second terminal device
