Question: In a telecom network utilizing Diameter charging applications, what does the Accounting-Input-Octets AVP (AVP code 363) primarily measure for a data flow?
Option 1: The total number of packets transmitted during a billing cycle.
Option 2: The volume of downlink traffic in bytes per second.
Option 3: The number of octets transmitted in uplink traffic during a data container recording interval.
Option 4: The signal strength of User Equipment (UE) connections.
Explanation: This is correct because the Accounting-Input-Octets AVP specifically measures the volume counts for **uplink** traffic (data sent from the user to the network) during a defined recording interval, quantified in octets. This measurement is crucial for charging and billing purposes in telecom networks, allowing operators to accurately account for data usage.
