What is a 5QI?
A 5G QoS Identifier (5QI) is a scalar that references a pre-defined set of QoS characteristics in the 5G System. Each standardised 5QI maps to a Resource Type (GBR, Non-GBR, or Delay Critical GBR), a Default Priority Level, a Packet Delay Budget (PDB), a Packet Error Rate (PER) target, and — for GBR flows — a Default Maximum Data Burst Volume (MDBV) and Default Averaging Window. The canonical list lives in 3GPP TS 23.501 Table 5.7.4-1 and is reused across the AMF, SMF, PCF and NG-RAN.
GBR vs Non-GBR vs Delay-Critical GBR
GBR (Guaranteed Bit Rate) flows get a network commitment on bandwidth — voice, live video, mission-critical push-to-talk. Non-GBR flows are best-effort — web, buffered video, default internet bearer (5QI 9). Delay-Critical GBR is the URLLC family: the PDB is 5–30 ms, PER is 10⁻⁴ or tighter, and MDBV is constrained. These are the 5QIs industrial automation, high-voltage power grids and V2X collision avoidance rely on.
Picking the right 5QI
VoNR typically runs on 5QI 1 (conversational voice). IMS signalling uses 5QI 5. Default data bearer is 5QI 9. Cloud gaming and XR aim for 5QI 80 or 87–90. Operators can also define non-standard 5QIs in their PCF by signalling a full set of QoS characteristics inline, but the 5QIs on this page are the ones every interoperable device and core network understands out of the box.

Frequently Asked Questions
Which 5QI is used for VoNR?
Voice over NR typically uses 5QI 1 (Conversational Voice — GBR, priority 20, PDB 100 ms, PER 10⁻²). IMS signalling for call setup rides on 5QI 5.
Which 5QI for URLLC industrial automation?
Discrete Automation Type 1 uses 5QI 82 (Delay Critical GBR, 10 ms PDB, 10⁻⁴ PER, 255-byte MDBV). Type 2, with a larger payload, maps to 5QI 83. For high-voltage electricity distribution the answer is 5QI 85 with a 5 ms PDB and 10⁻⁵ PER.
Can operators add custom 5QIs?
Yes. 3GPP allows dynamically signalled, non-standard 5QIs where the PCF pushes the full QoS characteristics (resource type, priority, PDB, PER, MDBV, averaging window) to the NG-RAN and SMF. The standardised 5QIs on this page are the pre-configured shortcuts — they do not need to be signalled per-flow because every NF already knows what they mean.
How does 5QI map to LTE QCI?
Most 5QIs inherit directly from the QCI table in TS 23.203. 5QI values 1–9 have the same meaning as QCIs 1–9, and the 6x / 7x / 8x ranges for mission-critical and V2X were first added to QCI and then brought into 5QI. The 8x Delay-Critical GBR range is the main 5G-specific addition.
How to use the 5QI Reference Lookup
- Search by service or number. Type a service name (such as voice, gaming, or automation), a 5QI number, or a resource type into the search box.
- Filter by resource type. Tick or untick GBR, Non-GBR and Delay Critical GBR to narrow the table.
- Tighten priority, PDB and PER. Drag the priority and packet-delay-budget sliders and pick a packet-error-rate threshold to find flows that meet a hard requirement.
- Sort the columns. Click the 5QI, Resource Type, Priority or PDB headers to sort ascending or descending.
- Expand a row. Click any 5QI to see its full QoS budget and a note on how that flow is typically configured at the gNB and UPF.
Frequently asked questions
- What is 5QI 1 used for?
- 5QI 1 is conversational voice. It is a GBR (Guaranteed Bit Rate) flow with priority level 20, a 100 ms packet delay budget and a 10⁻² packet error rate, which is the profile Voice over NR (VoNR) speech runs on. The matching IMS signalling for call setup rides on 5QI 5.
- What is the difference between GBR and non-GBR in 5G?
- A GBR flow gets a bandwidth commitment from the network with admission control — voice, live video, mission-critical push-to-talk. A non-GBR flow is best-effort and shares the remaining capacity, policed by an aggregate maximum bit rate (AMBR) rather than a guaranteed rate — web browsing, buffered video, the default internet bearer. Delay-Critical GBR is a third category for URLLC, adding a tight packet delay budget and a maximum data burst volume.
- Which 5QI is the default bearer?
- The default best-effort internet bearer typically uses 5QI 9 — a non-GBR flow with priority 90 and a 300 ms packet delay budget. It carries TCP-based traffic such as web, email and buffered video where there is no guaranteed-rate requirement.
