Claim 15:
16. An apparatus, comprising: a memory, a transceiver, and a processor, wherein the memory is configured to store computer programs, the transceiver is configured to send and receive data under a control of the processor, and the processor is configured to read the computer programs in the memory and perform the following operations:
receiving a Session Management (SM) policy modification request for a Protocol Data Unit (PDU) session, wherein the SM policy modification request triggers establishment of a first Quality of Service (QoS) flow in the PDU session, and the PDU session is established by a first terminal;
in response to no data transmission tunnel having a same identifier as a flow identifier of the first QoS flow existing between a first User Plane Function (UPF) of a first satellite and a second UPF of a second satellite, establishing a first data transmission tunnel between the first UPF and the second UPF, wherein the first satellite is a satellite serving the first terminal, the second satellite is a satellite serving a second terminal, and the second terminal is determined based on application layer information; and
instructing the first UPF to transmit data of the first QoS flow through the first data transmission tunnel.
