TRANSMISSION POLICY DETERMINATION METHOD, POLICY CONTROL METHOD, AND DEVICE

摘要

Embodiments of this application relate to the field of communication technologies, and provide a transfer policy determining method, a policy control method, and an apparatus, to resolve a conventional-technology problem that a PCF network element does not have enough information to determine an accurate BDT policy. The solution includes: A policy control network element receives first information of a network in a first network area from a slice management and control network element, where the first information includes at least one of load information of the network in a first time interval and load information of at least one network slice in the first time interval, and the network includes the at least one network slice. The policy control network element determines, based on the first information, a service data transfer policy of a terminal located in the first network area.
