Abstract: A data transmission method includes receiving third information from a session management network element. The third information includes first transmission delay information of data packet transmission between an access network element and a terminal device. The data transmission method further includes determining congestion control parameter information based on the third information, and sending the congestion control parameter information to the data sending network element. The congestion control parameter information is useable to indicate that a data amount of a first service sent by a data sending network element to a second user plane function network element for the first time after a user plane function network element that is configured to serve the first service in the data sending network element is switched from a first user plane function network element to the second user plane function network element.

Abstract: A communication method, apparatus, and system. Through capability exposure of a radio access network device, the radio access network device may obtain a congestion parameter of a radio access network based on indication information, to determine whether congestion occurs in the radio access network. In addition, the radio access network device may send the congestion parameter to a proxy entity. The proxy entity may identify the congestion parameter of the radio access network, so that congestion control on a wireless network can be optimized.
