Section: 5.7.1.2 QoS Profile
Content: A QoS Flow may either be 'GBR' or 'Non-GBR' depending on its QoS profile. The QoS profile of a QoS Flow is sent to the (R)AN and it contains QoS parameters as described below (details of QoS parameters are described in clause 5.7.2): - For each QoS Flow, the QoS profile shall include the QoS parameters: - 5G QoS Identifier (5QI); and - Allocation and Retention Priority (ARP). - For each QoS Flow, the QoS profile may also include the QoS parameters: - PDU Set QoS Parameters (described in clause 5.7.7). - For each Non-GBR QoS Flow only, the QoS profile may also include the QoS parameter: - Reflective QoS Attribute (RQA). - For each GBR QoS Flow only, the QoS profile shall also include the QoS parameters: - Guaranteed Flow Bit Rate (GFBR) - UL and DL; and - Maximum Flow Bit Rate (MFBR) - UL and DL; and - In the case of a GBR QoS Flow only, the QoS profile may also include one or more of the QoS parameters: - Notification control; - Maximum Packet Loss Rate - UL and DL. NOTE: In this Release of the specification, the Maximum Packet Loss Rate (UL, DL) is only provided for a GBR QoS Flow belonging to voice media. Each QoS profile has one corresponding QoS Flow identifier (QFI) which is not included in the QoS profile itself. The usage of a dynamically assigned 5QI for a QoS Flow requires in addition the signalling of the complete 5G QoS characteristics (described in clause 5.7.3) as part of the QoS profile. When a standardized or pre-configured 5QI is used for a QoS Flow, some of the 5G QoS characteristics may be signalled as part of the QoS profile (as described in clause 5.7.3).
