Reflective quality of service qos method and apparatus

A reflective quality of service (QOS) method, comprising:

• generating, by a network device, a first packet;
• and
• sending the first packet to a terminal device, wherein the first packet comprises third indication information, wherein the third indication information indicates to the terminal device to determine a first rule in a first reflective QoS manner, or the third indication information indicates that the first packet is a packet of a first QoS type;
• wherein the first rule comprises a QoS rule and/or a QoS flow to DRB mapping rule, wherein the first reflective QoS manner indicates the terminal device to identify classification information of a packet, and wherein the classification information is associated with distinguishing between packets in a same internet protocol (IP) flow.

A reflective quality of service (QOS) method, wherein the method comprises:

• generating, by a network device, fourth indication information;
• and
• sending the fourth indication information to a terminal device, wherein the fourth indication information indicates the terminal device to determine a first rule for a first information element in a first reflective QoS manner, wherein the first rule comprises a QoS rule or a QoS flow to data radio bearer (DRB) mapping rule, the first reflective QoS manner indicates the terminal device to identify classification information of a packet, and the classification information is for distinguishing between packets in a same internet protocol (IP) flow;
• wherein the information element comprises at least one of a QFI a QoS flow identifier (QFI), a DRB identifier, a network slice identifier, a data network name, a logical channel identifier, a logical channel group identifier, or an IP flow identifier.
