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.

Abstract: This application provides an information transmission method and apparatus, and a storage medium. The method includes: A first server sends first information to a PCF, where the first information is for measuring a communication KPI corresponding to a first device, and the communication KPI includes a communication KPI between a UPF and the first server. The PCF sends a communication indicator measurement policy to an SMF based on the first information. The SMF sends a communication indicator measurement rule to a UPF according to the communication indicator measurement policy, and sends second information to the first server. The second information includes the communication KPI corresponding to the first device, or a parameter for obtaining the communication KPI corresponding to the first device. In this way, the first server may obtain the KPI between the UPF and the first server based on the second information.
