Question: In a Policy and Charging Control (PCC) scenario with two PCC rules having Application Detection Filters for a specific service data flow, which rule will be applied first by the PCEF for enforcement of QoS and charging control if Rule A has a Precedence AVP value of 10 and Rule B has a Precedence AVP value of 5?
Option 1: Rule A (Precedence AVP value: 10) will be applied first because higher values indicate higher priority.
Option 2: Rule B (Precedence AVP value: 5) will be applied first because lower values indicate higher priority.
Option 3: Both rules will be applied simultaneously as the Precedence AVP only affects service data flow detection, not application detection filters.
Option 4: The order of application is determined by other factors within the Charging Rule Definition AVP, not by the Precedence AVP.
Explanation: A lower value in the Precedence AVP indicates higher evaluation precedence. Thus, Rule B (with a value of 5) will be applied first by the PCEF for QoS and charging control enforcement, ensuring higher-priority rules are executed before lower-priority ones.
