POLICY CONTROL METHOD, RELATED APPARATUS, AND POLICY AND CHARGING CONTROL SYSTEM

摘要

Embodiments of the present invention provide a policy control method, a related device and a policy and charging control system in a mobile communication system. The policy control method includes: obtaining description information of two or more sub-flows, wherein the two or more sub-flows belong to a same application; respectively generating policy and charging control PCC rules for the two or more sub-flows according to the description information of the two or more sub-flows; and transmitting at least one generated PCC rule to a PCEF entity or a bearing binding and event report function BBERF entity, so as to perform policy control for the sub-flows by the PCEF entity or the BBERF entity. With the policy control method, the related device, and the policy and charging control system according to embodiments of the present invention, a network side entity of the 3GPP network learns that the same application includes multiple sub-flows, and learns the description information of each sub-flow, such as IP address information, related information of QoS and so on, so that policy control for multiple sub-flows can be performed correctly.
