Abstract: This application provides example rule processing methods. One example method includes receiving, by a user plane function node, a first data packet. The user lane function node can then perform rule matching on the first data packet to obtain a first predefined rule. In response to determining that no quality of service (QoS) flow meets the first predefined rule, the user lane function node can then send a first message to a session management function node, where the first message includes information about the first predefined rule. The user lane function node can then receive rule update information sent by the session management function node, where the rule update information includes an identifier of a first QoS flow, and where the first QoS flow meets the first predefined rule.
