1. A method for controlling disorder of downlink data, wherein the method comprises:
receiving, by a second user plane device, indication information from a control plane device, wherein a transmission path before switching passes through a data network, a session anchor, and a first user plane device, and a transmission path after switching passes through the data network, the session anchor, and the second user plane device;
receiving, by the second user plane device, downlink data from the session anchor;
buffering, by the second user plane device according to the indication information, the downlink data received from the session anchor; and
sending, by the second user plane device, the buffered downlink data to a radio access network device after reception, by the second user plane device, of an end marker from the first user plane device;
wherein there is a connection between the first user plane device and the second user plane device through which the end marker is passed from the first user plane device to the second user plane device.
