具体而言，该AS向终端设备发送数据时，数据首先到达DNN，假设AS需要将第一数据P1发送给UE1，将第二数据P2发送给UE2，该第一数据P1的发送时间早于第二数据P2，则期望该第一数据早于该第二数据到达对应的目的终端。该DNN接收到该第一数据和第二数据后，可以根据该第一数据和第二数据中包括的目的终端的信息将该第一数据和第二数据发送给对应的UPF实体，例如，该第一数据中可以包括UE1的地址信息或设备标识信息等用于标识该UE1的信息，从而该DNN接收到第一数据后，可以根据该第一数据中的目的节点信息将该第一数据发送给UPF实体1，进一步地，该UPF实体1可以确定该第一数据向下一级网络节点即gNB1发送该第一数据的时间，同样地，该UPF实体2也可以确定将该第二数据发送给下一级网络节点即gNB2的时间。Specifically, when the AS sends data to the terminal device, the data first arrives at the DNN. Assume that the AS needs to send the first data P1 to the UE1 and the second data P2 to the UE2. The first data P1 is sent earlier than the first For the second data P2, it is expected that the first data arrives at the corresponding destination terminal earlier than the second data. After receiving the first data and the second data, the DNN may send the first data and the second data to the corresponding UPF entity according to the information of the destination terminal included in the first data and the second data, for example, the The first data may include information for identifying UE1 such as the address information or device identification information of UE1, so that after receiving the first data, the DNN may send the first data according to the destination node information in the first data To the UPF entity 1, further, the UPF entity 1 may determine the time when the first data sends the first data to the next-level network node, gNB1, and similarly, the UPF entity 2 may also determine to send the second data Time for the next level of network node, gNB2.
