1. A method, comprising:
receiving a first data packet by a user plane function (UPF) network element;
determining, by the UPF network element, whether the first data packet is an uplink data packet or a downlink data packet based on a device that sent the first data packet;
generating, by the UPF network element, first indication information that indicates that the first data packet is the uplink data packet, or indicates that the first data packet is the downlink data packet; and
sending, by the UPF network element, the first data packet and the first indication information to an access network device, wherein the first indication information is used by the access network device to determine an access network (AN) packet delay budget (PDB) of a first quality of service (QOS) flow corresponding to the first data packet.
