The present invention provides a charging processing method, a centralized network control node, a function node, and a system. The method includes: receiving, by an SNC in a centralized manner, a service bearer setup request sent by a user; obtaining a corresponding charging policy from a PCRF entity according to characteristic information in the request; sending charging control information including the charging policy to a function node FN; and receiving charging information that is reported by the FN according to the charging control information and a service data flow to be processed, and interacting with a charging system, so that the charging system performs, according to the charging information, charging settlement processing on the service data flow to be processed. Functions of a control plane and a data plane are divided in a charging process, and are respectively processed by an SNC and an FN. When the FN in a network cannot meet a requirement, a charging processing capability of the network can be expanded as long as an FN is added, which facilitates implementation of flexible configuration, facilitates centralized charging control and distributed data processing, and helps improve processing efficiency. |
