1. A non-transitory computer-readable storage medium storing a program to be executed by one or more processors, the program including instructions, which when executed by the one or more processors cause an apparatus to perform the operations of:
receiving 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 apparatus;
receiving downlink data from the session anchor;
buffering, according to the indication information, the downlink data received from the session anchor; and
sending the buffered downlink data after reception, by the apparatus, of an end marker from the first user plane device,
wherein there is a connection between the first user plane device and the apparatus through which the end marker is passed from the first user plane device to the apparatus.
