Service data flow transmission method, communication apparatus, and communication system

A communication apparatus comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium configured to storestoring a program, comprising instructions that, when to be executed by the processor, the program including instructions for cause the communication apparatus to perform the operations:
• receiving characteristic information of a service data flow and quality of service (QOS) information of the service data flow, wherein the characteristic information of the service data flow indicates traffic characteristic information corresponding to different time slices within the service data flow in a time period, and the QoS information indicates QoS class identifiers (QCIs) corresponding to the different time slices;
• determining, based on the characteristic information and the QoS information of the service data flow, a configuration parameter corresponding to a data packet of the service data flow;
• and
• sending the data packet to a terminal device based on the configuration parameter.

A communication system, comprising an access network device and a session management network element, wherein

• the session management network element is configured to send characteristic information of a service data flow and quality of service (QOS) information of the service data flow to the access network device, wherein the characteristic information of the service data flow indicates traffic characteristic information corresponding to different time slices within the service data flow in a time period, and the QoS information indicates QoS class identifiers (QCIs) corresponding to the different time slices;
• and
• the access network device is configured to:
• receive the characteristic information of the service data flow and the QoS information of the service data flow from the session management network element;
• determine, based on the characteristic information and the QoS information of the service data flow, a configuration parameter corresponding to a data packet of the service data flow;
• and
• send the data packet to a terminal device based on the configuration parameter.
