Methods and Equipment for Performing Reflective Quality of Service (QoS) in Wireless Communities

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for performing reflection-type QoS in a wireless communication system. SOLUTION: The method receives a downlink PDU from a network via a downlink data wireless bearer (DRB), and the downlink PDU receives a QFI (QoS flow identifier) and a QoS flow for an AS (Access Stratum) level. Includes a first indicator related to and a second indicator related to quality of service (NOS) levels. The first indicator indicates that the downlink mapping rule between the QoS flow and the DRB of the downlink PDU is stored as the uplink mapping rule between the QoS flow and the DRB for the uplink transmission, and the second indicator is Notify the NAS hierarchy of the QoS of the downlink PDU.
