Figure 16 describes each QCI type and provides an application example for each type.
Figure 16: QCI Types
GBR provides a guaranteed bit rate and is associated with parameters such as GBR and MBR,
as follows:

GBR:
The minimum guaranteed bit rate. Specified independently for the UL and
DL.

MBR:
The maximum guaranteed bit rate. Specified independently for the UL and
DL.
The Non-GBR bearer does not provide a guaranteed bit rate and has the parameter
UE-AMBR, as follows:

UE-AMBR:
The UE aggregate maximum bit rate is the maximum allowed total
non-GBR throughput among all APNs to a specific UE.
QoS provisioning per UE can be either iHSS (in EPC and BreezeVIEW) or AAA.

BreezeCOMPACT Equal Time/Equal Rate Scheduler
The system enables two scheduling schemes to support fairness between different UEs. It takes into account
scenarios in which the system is overloaded and has limited air resources. The BreezeCOMPACT scheduler
supports the following scheduling schemes: Equal Time and Equal Rate.
In order to ensure GBR committed rates in QCI 1-4, Equal rate scheduling is assigned always to
the GBR portion.
For the un-committed (MBR / AMBR), operator can configure the eNB for Equal time or Equal
rate.
