Claim 11:
12. A communications apparatus, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
receiving data of a quality of service (QoS) flow through a default data radio bearer (DRB); and
sending a data notification message from a central unit-user plane (CU-UP) of a radio access network (RAN) to a central unit-control plane (CU-CP) of the RAN, wherein the data notification message notifies the CU-CP that a data packet of the QoS flow is received for a first time through the default DRB and comprises a QoS flow identity (ID) of the QoS flow and a protocol data unit (PDU) session ID identifying a PDU session, wherein the PDU session comprises the data of the QoS flow.
