1. A quality of service (QoS) parameter processing method comprising:
obtaining, by a session management function device, a core network (CN) packet delay budget (PDB) between a target access network device and a user plane function device for a QoS flow, wherein the target access network device serves a terminal device after a handover;
sending, by the session management function device and to an access and mobility management function device, a context update response message comprising the CN PDB to prompt the access and mobility management function device to send a handover request message comprising the CN PDB to the target access network device;
receiving, by the target access network device, the CN PDB;
determining, by the target access network device, an access network (AN) PDB between the terminal device and the target access network device based on the CN PDB and an end-to-end PDB between the terminal device and the user plane function device; and
scheduling, by the target access network device, an air interface resource between the terminal device and the target access network device based on the AN PDB.
