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: In a method, a first transmission server determines, based on first quality of service measurement information and/or first quality of service monitoring information, that the first transmission server is to be switched, and determines a second transmission server. Quality of service of serving by the second transmission server connected to the first transmission client via the first access network device and a second user plane function network element satisfies a quality of service requirement of an application layer application. In other words, the first transmission server may determine, based on QoS information obtained through measurement and UE-RAN QoS information, RAN-UPF QoS information, or UE-RAN-UPF QoS information obtained through 5GC monitoring, whether the first transmission server is to be switched. In addition, the first transmission server may determine the second transmission server that satisfies the QoS requirement, so that the first transmission server can be switched to the second transmission server.

Abstract: The disclosure provides a communication method and apparatus. The method is performed by an access network device, and includes: receiving reference information of a first multicast/broadcast service (MBS) session from an access and mobility management network element, where the reference information of the first MBS session indicates a feature of the first MBS session; and triggering, based on the reference information, a first receive end corresponding to the first MBS session to enter an idle state or a radio resource control (RRC) inactive state. In this application, a receive end corresponding to an MBS session is not always in an RRC connected state, and the method can avoid maintaining a large quantity of receive ends corresponding to the MBS session in the RRC connected state for a long term, and further save processing resources of the access network device.

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.
