Abstract: Embodiments of this application provide a method, an apparatus, and a system for reporting data usage, so that for a PDU session into which a UL CL user plane network element or a BP user plane network element is inserted, statistics can be accurately collected on data usage. The method includes: An aggregate user plane network element determines discarded data usage of the aggregate user plane network element, and sends the discarded data usage to a session management network element. The first session management network element receives the discarded data usage, and receives transport data usage of one or a plurality of anchor user plane network elements, which are anchor user plane network elements connected to the aggregate user plane network element. The first session management network element determines actual data usage of a terminal device based on the discarded data usage and the transport data usage.

Abstract: A multicast communication method and a communication apparatus provide for transmission of data of a multicast service using a PDU session established by a terminal device to improve network element utilization. An AF network element sends first multicast service indication information to a session management network element indicating a first multicast service. The session management network element sends, based on the first multicast service indication information, multicast service information to an access network device that serves a terminal device. The access network device establishes an association relationship between the terminal device and the first multicast service based on the multicast service information, so that the access network device can send, when receiving data of the first multicast service, the data of the first multicast service to the terminal device using a PDU session.

Abstract: Embodiments of this application provide a data transmission method, with step including receiving, by user equipment, a first message, where the first message is used to instruct the user equipment to activate a reflective quality of service RQ mechanism; generating, by the user equipment, an implicit quality of service implicit QoS rule according to the RQ mechanism; receiving, by the user equipment, a second message, where the second message is used to instruct the user equipment to stop using the RQ mechanism; and stopping, by the user equipment, using the RQ mechanism, and deleting the implicit QoS rule. The user equipment receives the second message indicating that using of the RQ mechanism needs to be stopped, and deletes the implicit QoS rule, so as to implement switching between an explicit QoS rule and the implicit QoS rule, and flexibly configure a QoS rule for uplink data according to a policy of an operator.
