Section: 5.7.1.3 Control of QoS Flows
Content: The following options are supported to control QoS Flows: 1) For Non-GBR QoS Flows, and when standardized 5QIs or pre-configured 5QIs are used and when the 5QI is within the range of the QFI (i.e. a value less than 64), the 5QI value may be used as the QFI of the QoS Flow. (a) A default ARP shall be pre-configured in the AN; or (b) The ARP and the QFI shall be sent to RAN over N2 at PDU Session Establishment or at PDU Session Modification and when NG-RAN is used every time the User Plane of the PDU Session is activated; and 2) For all other cases (including GBR and Non-GBR QoS Flows), a dynamically assigned QFI shall be used. The 5QI value may be a standardized, pre-configured or dynamically assigned. The QoS profile and the QFI of a QoS Flow shall be provided to the (R)AN over N2 at PDU Session Establishment/Modification and when NG-RAN is used every time the User Plane of the PDU Session is activated. Only options 1b and 2 may apply to 3GPP ANs. Options 1a, 1b and 2 may apply to Non-3GPP access. NOTE: Pre-configured 5QI values cannot be used when the UE is roaming.
