Abstract: Various embodiments provide a packet transmission method and an apparatus. In those embodiments, a first device supports a first protocol layer, and replicates a packet at the first protocol layer. A second device supports a second protocol layer, and deduplicates the packet at the second protocol layer. When receiving a first packet, a first access device converts a sequence number of the first protocol layer in the first packet into a sequence number of the second protocol layer, and then sends, to the second device, a second packet that carries the sequence number of the second protocol layer and a data packet of the first packet. For example, if the first access network device receives two packets having same data packets, the first access network device separately coverts sequence numbers in the two packets without performing operations of first deduplicating and then replicating the packet.

Abstract: The present invention provides a method, an apparatus, and a system for deploying a service flow forwarding function. The method includes: sending, by a control plane network element, a notification message to an infrastructure controller, the notification message includes at least one forwarding identifier corresponding to a user service flow and includes an identifier of a target forwarding plane network element providing service processing for the user service flow; the notification message is used to instruct the infrastructure controller to determine a first forwarding rule including the at least one forwarding identifier and the identifier of the target forwarding plane network element and send the first forwarding rule to an infrastructure forwarder controlled by the infrastructure controller. The present invention is used for service flow forwarding, resolves a problem that flexibility of service flow forwarding is relatively low, and achieves an effect of improving flexibility of service flow forwarding.

Abstract: A communications method and apparatus, where the method includes: sending, by a session management network element, first indication information when the session management network element determines, based on first information, to establish a first low-latency service flow for a session, wherein the first indication information is used to indicate to set the session to an always-on session. According to solutions of this application, when determining to establish the low-latency service flow, the session management network element flexibly indicates to a terminal apparatus to set the session to the always-on session. This avoids a resource waste caused by setting the session to the always-on session all the time, and avoids a transmission latency caused when the session is not set to the always-on session in time, such that resource utilization and transmission efficiency are improved.

Abstract: The present disclosure relates to quality of service (QoS) information notification methods, devices, and systems. In one example method, a user plane network element obtains a first QoS notification, where the first QoS notification includes first QoS information used to indicate QoS of a target service. The user plane network element sends first indication information to an application network element to which a QoS notification needs to be reported, where the first indication information is used to indicate a second QoS notification, the second QoS notification includes second QoS information of the target service, and the first QoS notification is the same as the second QoS notification, or the second QoS notification is determined based on the first QoS notification.
