1. A communication method, comprising:
determining that a first session is a multi-access protocol data unit (MA-PDU) session, wherein data flows of the first session are transmitted on a data transmission channel of a first access technology and data transmission channels of a second access technology, the data transmission channels of the second access technology include a first data transmission channel and a second data transmission channel;
an aggregation point of the data transmission channel of the first access technology and the first data transmission channel is a first user plane network element; and
an aggregation point of the first data transmission channel and the second data transmission channel is an uplink classifier (UL CL);
sending a first aggregate maximum bit rate (AMBR) to the first user plane network element, wherein:
the first AMBR is used by the first user plane network element to control one or more data flows that are in the data flows of the first session and that are transmitted on the data transmission channel of the first access technology;
sending a second AMBR to the UL CL, wherein:
the second AMBR is used by the UL CL to control data flows that are in the data flows of the first session and that are transmitted on the data transmission channels of the second access technology.
