What is relation between user throughput and APN-AMBR?

Hi Experts,
What is relation between user throughput and APN-AMBR?

Throughput is limited by AMBR.

Yes. @RFSpecialist, is it set on Core side?

Yes. At PGW.

In HSS per IMSI based.

PGW enforces it. UE-AMBR and APN-AMBR in HSS profiles per IMSI.

anybody knows what is the difference btw extended and extended -2?

Do you know how to get APN AMBR values in 5G NSA L3 message? I saw the values of APN ABMR in LTE NAS signalling , but I think this is the threshold of 4G LTE due to UE use LTE first in NSA , In fact, we still collect many samples with value higher than threshold.

This is Aggregate Maximum Bit Rate (AMBR) is the total maximum bit rate of all Non-GBR connections for that particular APN .For an example.IMS APN this value is the SIP signalling max load.Simply putting it Maximum rate of QCI 5.
