1. A data flow transmission method, performed by network-side device and comprising:
determining a mapping relationship between Quality of Service (QOS) flows of Multicast and Broadcast Services (MBS) and a radio bearer with multicast and broadcast transmission and a mapping relationship between the QoS flows of the MBS and a radio bearer with unicast transmission;
transmitting the QoS flows through at least one of the radio bearer with multicast and broadcast transmission or the radio bearer with unicast transmission based on the mapping relationship;
wherein the QoS flows mapped to the radio bearer with multicast and broadcast transmission in the QoS flows of the MBS and the QoS flows mapped to the radio bearer with unicast transmission in the QoS flows of the MBS are partially or totally different.
