Abstract: A network standard switching method includes obtaining a network standard switching instruction including a target priority. The network standard switching instruction instructs a terminal device to be handed over to a target network whose standard is a target standard, and a priority of the target network is greater than a priority of a network in which the terminal device is currently located. The method further includes releasing a network link between the terminal device and a currently accessed first base station, intercepting and caching to-be-sent application-layer data of the terminal device, discarding a paging message in a packet switched (PS) domain received from a first-priority network to the terminal device, and handing over to the target network.
