Feature Description

The APN-AMBR is a subscription parameter that is stored per APN in the HSS. S-GW provides APN-AMBR during default bearer establishment procedure. APN-AMBR limits the aggregate bit rate that can be expected to be provided across all non-GBR bearers and across all PDN connections of the same APN. Each of those non-GBR bearers can potentially utilize the entire APN-AMBR, for example, when the other non-GBR bearers do not carry any traffic. The P-GW enforces the APN-AMBR in downlink and uplink direction.
