Abstract

The invention provides a transmission method, a sending end PDCP (Packet Data Convergence Protocol) entity and a receiving end PDCP entity. The method corresponding to the sending end PDCP entity comprises the step of sending a target PDCP PDU (Protocol Data Unit) carrying an SDAP End-Marker Control PDU. According to the data transmission method, the SDAP End-Marker Control PDU is carried in the PDCP PDU, so that the SDAP End-Marker Control PDU can be transmitted along with the PDCP PDU. The transmission method is simple to implement, and the system overhead required by transmission is low.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a transmission method, a PDCP entity at a sending end, and a PDCP entity at a receiving end. Background technique [0002] SDAP (Service Data Adaptation Protocol, Service Data Adaptation Protocol) introduces a control PDU (Protocol Data Unit, Protocol Data Unit), that is, SDAP End-Marker Control PDU (Service Data Adaptation Protocol End Marker Control Protocol Data Unit). The End-Marker Control PDU can be used in the SDAP entity on the UE (User Equipment, user equipment) side, and is used to instruct to stop the SDAP SDU (Service Data Unit, service data unit) mapping of the QoS (Quality of Service, quality of service) flow. [0003] However, the SDAP End-Marker Control PDU format is different from the normal SDAP data PDU, so that it cannot be processed in the PDCP entity in the same way as other SDAP data. Contents of the invention [0004] The purpose of th...
