Abstract
Embodiments of this application provide an uplink PDR generation method, an apparatus, and a system, to resolve a problem in a conventional technology that an uplink data packet may be discarded because a PCF network element may not include uplink SDF information when generating a PCC rule including an RQC indication. The method includes: A session management network element receives a first policy and charging control PCC rule from a policy control network element, where the first PCC rule includes downlink service data flow SDF information that corresponds to a first service. When the first PCC rule includes a reflective quality of service control RQC indication, the session management network element generates, according to the first PCC rule, a first uplink PDR that corresponds to the first service. The session management network element sends, to a user plane network element, the first uplink PDR that corresponds to the first service.
