Reflective quality of service configuration method and device, and information sending method and device

Abstract

Disclosed are a reflective quality of service configuration method and device, an information sending method and device, user equipment, a base station, and a computer readable storage medium. The reflective quality of service configuration method comprises: receiving first indication information sent by an SDAP sending end, the first indication information being used for indicating a sequence number (SN) of a PDCP packet corresponding to the first SDAP packet sent according to a new configuration of a pre-established DRB, or the SN of the PDCP packet corresponding to the last SDAP packet sentaccording to an old configuration of the pre-established DRB; obtaining the received SN of the PDCP packet corresponding to the SDAP packet; and comparing the obtained SN with the SN indicated by thefirst indication information to determine whether the corresponding SDAP packet contains an SDAP packet header. By means of embodiments of the present invention, whether the corresponding SDAP packetcontains an SDAP packet header can be determined; the implementation mode does not require extra bits to be carried in the packet header, and the overhead of the packet header is low.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for configuring Reflective Quality of Service (QoS), an information sending method and device, user equipment, a base station, and a computer-readable storage medium. Background technique [0002] With the development of communication technology, the fifth generation of mobile communication technology (5th Generation, 5G for short) appears. The 5G new air interface (new radio, NR) user plane introduces a new protocol layer on top of the existing packet data convergence protocol (PDCP) layer. [0003] For the convenience of description, the newly introduced protocol layer is called the service data adaptation protocol (Service data adaptation protocol, SDAP) layer, wherein, the SDAP layer is located at the upper layer of the PDCP layer, and is responsible for transferring the quality of service (QoS) flow (flow) of the upper layer ) is ma...

AI Technical Summary

Problems solved by technology

[0007] At present, there is the following problem: when a DRB is configured to include or not include the SDAP header, and then reconfigure whether the DRB includes the SDAP header, the SDAP data that has been submitted to the PDCP layer by the SDAP sender will continue to use the previous SDAP Packet header configuration, the new configuration will be used for data that has not been submitted to the PDCP layer

For the SDAP receiving end, the SDAP data with the old configuration and the SDAP data with the new configuration may be received at the same time, causing the SDAP receiving end to be unable to distinguish
