USING SDAP HEADERS FOR HANDLING OF AS/NAS REFLECTIVE QOS AND TO ENSURE IN-SEQUENCE PACKET DELIVERY DURING REMAPPING IN 5G COMMUNICATION SYSTEMS

摘要

In an aspect of the disclosure, an apparatus is provided. The apparatus receives a downlink data packet and determines a service data flow associated with the downlink data packet. The apparatus extracts, from the downlink data packet, a Non-Access Stratum (NAS) Reflective QoS Indication (RQI) indicator that instructs the UE to map a service data flow to the QoS flow. The apparatus further extracts, from the downlink data packet, a Quality of Service (QoS) flow identifier identifying a QoS flow. The apparatus generates a first NAS mapping that maps the service data flow to the QoS flow, in response to a determination that the service data flow is not mapped to the QoS flow at the apparatus. The apparatus further transmits, in accordance with the first NAS mapping, an uplink data packet associated with the service data flow through the QoS flow.
