This application provides a communication method and a communication apparatus, applied to the field of communication technologies. In the technical solutions provided in this application, a first network device receives a first splitting policy from a first core network element, where the first splitting policy indicates a QoS flow that is in a first PDU session and that is split to the first network device and/or a data volume that is of a QoS flow in the first PDU session and that is split to the first network device; and determines a first capability according to the first splitting policy, where the first capability is a capability that is in a capability of the first UE and that can enable the first network device to ensure the first splitting policy. In this application, in a core network splitting mechanism, a data transmission rate of UE is effectively increased.
