Section: 6.2.5.1.4.5 Deleting a derived QoS rule in the UE
Content: Upon expiry of timer T3583 associated with a derived QoS rule, the UE shall remove the derived QoS rule. Upon release of the PDU session, the UE shall remove the derived QoS rule(s) associated with the PDU session. If the network accepts the request from the UE to revoke the usage of reflective QoS and sets the value of the RQ timer to "deactivated" or zero, the UE shall remove the derived QoS rule(s) associated with the PDU session. Upon inter-system mobility from WB-N1 mode to NB-N1 mode or from NR connected to 5GCN to NB-N1 mode, the UE shall remove the derived QoS rule(s) associated with the PDU session that is kept active. When a derived QoS rule is deleted, the timer T3583 associated with the derived QoS rule shall be stopped.
