Abstract

A method for implementing the sequential transmission of uplink data during Qos stream remap is provided. An end tag packet is constructed by reserving a bit position 1 in an internetwork protocol (IP) header, the operation is simple and easy to implement, which effectively reduces the processing overhead of the SDAP layer when the receiving end identifies the uplink end tag packet, and can reserve two bits for the SDAP header, so that the size of the QFI field in the uplink SDAP header which is still under discussion can be enlarged by one bit.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a dual connection scenario in 5G cellular mobile communication, and in particular to a method for realizing sequential transmission of uplink data during Qos flow remapping. Background technique [0002] Multiple Radio Access Technology-Dual Connectiviti (MR-DC) is an evolution of the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (Evolved Summary of dual connectivity in UMTS TerrestrialRadio Access Network, referred to as E-UTRA). Wherein, user equipment (User Equipment, referred to as UE) is provided with access services by two different base stations, one provides E-UTRA access, and the other provides New Radio (New Radio, referred to as NR) access. One base station serves as a main station node (Main Node), and the other base station serves as a secondary node (Secondary Node, SN for short). NR-E-UTRA Dual Connectivity (NE-DC...
