Question: What happens to excess traffic when the Aggregate Maximum Bit Rate (APN-AMBR) limit is reached for non-Guaranteed Bit Rate (GBR) PDP Contexts/bearers within the same APN?
Option 1: Excess traffic is buffered and transmitted when bandwidth becomes available.
Option 2: Excess traffic is redirected to a different APN with available capacity.
Option 3: The system automatically upgrades the subscription to accommodate the excess traffic.
Option 4: Excess traffic may get discarded by a rate shaping function.
Explanation: APN-AMBR limits the aggregate bit rate across all non-GBR PDP Contexts/bearers and PDN connections of the same APN. When this limit is reached, to maintain network performance and adhere to the set bitrate cap, excess traffic cannot be accommodated in real-time, leading to potential discarding by a rate shaping function to prevent network congestion.
