  • Handling QoS Flow without a Mapping Data Radio Bearer
    Publication number: 20190313262
    Abstract: A PDU session and QoS flow handling mechanism is proposed when a QoS flow of a PDU session does not have a mapping DRB after a handover or a service request procedure. If the QoS flow is associated with a default QoS rule, the UE can locally release the PDU session, initiate a PDU session release procedure, send a 5GSM status message with proper cause, or assume the PDU session is not reactivated. On the other hand, if the QoS flow is not associated with a default QoS rule, the UE can locally delete the QoS flow, delete the QoS flow by using a PDU session modification procedure, or send a 5GSM status message with proper cause.
