5G QoS Parameters
This value is used as a reference to 5G QoS characteristics defined in clause TS 23 501 5.7.4 table.
This value will have a one-to-one mapping to standard combination of 5G QoS characteristics as specified in Table 5.7.4-1.
This parameter specifies the information about the priority level, the pre-emption capability and the pre-emption
This will help to decide if a QoS flow establishment/modification/handover may be accepted or needs to be rejected in the case of resource limitations.
Priority level 1-8 should be applied to QoS flow in home domain, 9-15 may be applied when UE is in roaming.
3. RQA: Reflective QoS Attribute
This is an optional parameter which indicates if a traffic carried on Q0S flow is subjected to Reflective QoS.
5G QoS characteristics
The below mentioned characteristics associated with 5QI.
Below are the characteristics that a QoS flow receives edge to edge between UE and the UPF:
1. Resource Type (GBR, Delay critical GBR or Non-GBR);
> It determines the type of QoS flow.
2. Priority Level;
> This indicates a priority in scheduling resources among QoS flows.
> Lowest value corresponds to highest priority.
3. Packet Delay Budget (including Core Network Packet Delay Budget);
> PDB defines the upper bound for the time that a packet may be delayed between UE and N6 terminal point at UPF.
4. Packet Error Rate;
> The Packet Error Rate (PER) defines an upper bound for the rate of PDUs that have been processed by the sender of a link layer protocol
5. Averaging window (for GBR and Delay-critical GBR resource type only);
> The Averaging window represents the duration over which the GFBR and MFBR shall be calculated.
6. Maximum Data Burst Volume (for Delay-critical GBR resource type only).
> MDBV denotes the largest amount of data that the 5G-AN is required to serve within a period of 5G-AN PDB.
1. One or more PDR in upstream and downstream provided by SMF to the UPF.
2. To the access network, the QoS profile is delivered to the AN (N2 port) by the SMF through the AMF or pre-configured in the AN.
3. The network sends one or more QoS rules to the terminal through N1 port.
