CONSERVING NETWORK RESOURCES DURING TRANSMISSION OF PACKETS OF INTERACTIVE SERVICES
A data transmission method includes receiving policy information transmitted by a core network device and related to a Protocol Data Unit (PDU) session, the policy information instructing transmission delay monitoring to be performed on data sub-packets obtained by splitting a data packet of an interactive service. The method further includes, in response to identifying that a data packet transmitted by a previous node is one of the data sub-packets obtained by splitting the data packet of the interactive service, detecting, according to the policy information in a process of transmitting the data sub-packets to a subsequent node, whether transmission of the data sub-packets meets a delay requirement. The method further includes, in response to detecting that the transmission of the data sub-packets does not meet the delay requirement, stopping transmitting remaining data sub-packets obtained by splitting the data packet of the interactive service to the subsequent node.
