Abstract

A data transmission method and apparatus, a system, and a storage medium are provided. In the method, a user plane function network element performs transmission through an established unicast user plane connection, and when sending data of a first service to an access network device, the user plane function network element can be configured to send only the data that is of the first service and that is carried in one data flow to improve use efficiency of resources on a core network side. Then, the access network device can send, in a multicast manner through an established unicast channel, the received data of the first service to a group of terminals corresponding to the data of the first service, and does not need to additionally establish a multicast channel and switch to the multicast channel, thereby further reducing data transmission delay.
