1. A method, comprising:
determining, by a first policy control network element, that a network performance in a first time window is lower than a preset threshold, wherein a first background data transfer policy includes the first time window, and the first background data transfer policy corresponds to a first reference identifier;
obtaining, by the first policy control network element from a first network element, all background data transfer policies stored in the first network element;
renegotiating, by the first policy control network element according to all the background data transfer policies stored in the first network element and based on the network performance, a background data transfer policy corresponding to the first reference identifier; and
sending, by the first policy control network element, a first message to the first network element, wherein the first message comprises the first reference identifier and first decision information, and the first decision information indicates that the background data transfer policy corresponding to the first reference identifier is being negotiated.
