Abstract: The present disclosure relates to data transmission methods and apparatus. One example method includes receiving, by user equipment, a first message sent by a control plane network element or a user plane network element, where the first message includes a correspondence between a first quality of service identifier (NQI) and a first reflective quality of service identifier (RQI), obtaining, by the user equipment, a second message sent by the user plane network element, and if the second message does not carry a second RQI, generating, by the user equipment, a first quality of service rule based on the second message and the correspondence between the first NQI and the first RQI, where the second RQI is used to instruct the user equipment to activate a reflective quality of service (RQ) mechanism.

Abstract: In a method for configuring a policy for user equipment (UE), a PCF network element receives policy information of the UE from a first network element. The policy information of the UE indicates a current policy of the UE. The PCF network element sends configuration information to the UE based on the policy information of the UE, and the configuration information instructs the UE to update the policy of the UE. The policy control function network apparatus then sends to the first network apparatus update information that comprises either the configuration information or an identifier of the configuration information.

Abstract: An information transmission method is provided. An apparatus receives a first session request from a third party application function, which includes identity information of the third party application function and identity information of a destination entity in a network. The apparatus establishes a first session with the third party application function; sends a second session request to the destination entity, which includes identity information of an anchor entity and the identity information of the third party application function. The apparatus establishes a second session with the destination entity; receives information reported by the destination entity, which includes a report event and identity information of the third party application function. The apparatus forwards the report event to the corresponding third party application function according to the identity information of the third party application function included in the information. Correct identification and forwarding of a packet flow is achieved.

Abstract: A method for sending an end marker, a device, and a system, where the method includes receiving, by a source AN through a source path between the source AN and a core-network user-plane device, a first end marker sent by the core-network user-plane device. The method further includes generating, by the source AN, N second end marker(s) based on the first end marker, where N is the number of source DRB(s) corresponding to the source path, and sending, by the source AN, the N second end marker(s) to a target AN through a forwarding path corresponding to the source path. According to the method, when a DRB is unknown to a core network, a target AN can accurately obtain a DRB-based end marker. This ensures correct sorting of downlink data of UE on a target DRB in a handover scenario.

Abstract: A data routing method and apparatus resolve a problem that data packet forwarding efficiency is greatly reduced because a service function instance sequence needs to be retrieved for each data packet according to a 5-tuple of a data flow to which the data packet belongs. The data routing method includes: receiving, by a traffic classifier, a data packet, where the data packet belongs to a first data flow; allocating, by the traffic classifier, a first data route identifier to the first data flow, where the first data route identifier is used to identify a service function chain of the first data flow and is used to identify the first data flow; adding, by the traffic classifier, the first data route identifier to the data packet; and sending, by the traffic classifier, the data packet to a service function forwarding device.

Abstract: The present application relates to the field of mobile communications technologies, and in particular, to a data packet sending apparatus and method and a data processing apparatus and method. In embodiments of the present application, at least two cached data packets are sent to a target network, so that a sending quantity is increased, that is, a case in which a data packet may be lost is fully considered, so as to ensure as much as possible that the target network can receive all data packets. In this way, a case in which the target network requests a server to retransmit data is avoided as much as possible, and if a retransmission mechanism-based transfer protocol is a TCP/IP protocol, a TCP disconnection is avoided as much as possible, and service transmission continuity is ensured.
