Title (EN) USING SDAP HEADERS FOR HANDLING OF AS/NAS REFLECTIVE QOS AND TO ENSURE IN-SEQUENCE PACKET DELIVERY DURING REMAPPING IN 5G COMMUNICATION SYSTEMS
(FR) UTILISATION D'EN-TÊTE SDAP POUR LA GESTION DE QOS RÉFLECTIVE AS/NAS ET POUR GARANTIR UNE DISTRIBUTION DANS L'ORDRE DE PAQUETS PENDANT LA RÉAFFECTATION DANS DES SYSTÈMES DE COMMUNICATION 5G
Abstract:
(EN) 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.
(FR) Un aspect de l'invention concerne un appareil. L'appareil reçoit un paquet de données de liaison descendante et détermine un flux de données de service associé au paquet de données de liaison descendante. L'appareil extrait, du paquet de données de liaison descendante, un indicateur d'indication de QoS réflective (RQI) hors strate d'accès (NAS) qui donne pour instruction à l'UE d'associer un flux de données de service au flux de QoS. L'appareil extrait en outre, du paquet de données de liaison descendante, un identifiant de flux de qualité de service (QoS) identifiant un flux de QoS. L'appareil génère un premier mappage de NAS qui associe le flux de données de service au flux de QoS, en réaction à une détermination selon laquelle le flux de données de service n'est pas associé au flux de QoS au niveau de l'appareil. L'appareil émet en outre, selon le premier mappage de NAS, un paquet de données de liaison montante associé au flux de données de service par l'intermédiaire du flux de QoS.
