Question: When provisioning authorized QoS per QCI for non-GBR (Non-Guaranteed Bit Rate) bearers in a 3GPP-GPRS IP-CAN type, which of the following AVPs are used in the QoS-Information AVP, and what is the handling of Guaranteed Bitrate values?
Option 1: Maximum-Requested-Bandwidth-UL AVP only, with Guaranteed Bitrate values always filled.
Option 2: Both Maximum-Requested-Bandwidth-UL AVP and/or Maximum-Requested-Bandwidth-DL AVP, with Guaranteed Bitrate values not filled up.
Option 3: QoS-Class-Identifier AVP alone, without referencing bandwidth or bitrate values.
Option 4: Neither Maximum-Requested-Bandwidth-UL nor Maximum-Requested-Bandwidth-DL AVPs are used, but Guaranteed Bitrate values are always provided.
Explanation: This is correct because, for non-GBR bearers in a 3GPP-GPRS context, the PCRF provisions authorized QoS per QCI using both uplink and/or downlink bandwidth AVPs (Maximum-Requested-Bandwidth-UL and/or Maximum-Requested-Bandwidth-DL) within the QoS-Information AVP, alongside the QoS-Class-Identifier AVP. Guaranteed Bitrate values are specifically not filled up for non-GBR bearers, as they apply to GBR scenarios. This approach allows for flexible bandwidth management without guaranteeing a specific bitrate, which is characteristic of non-GBR services.
