Question: What is the primary function of the ADC-Rule-Name AVP in a Policy and Charging Control (PCC) context?
Option 1: To specify the QoS parameters for a particular IP flow within a TDF session.
Option 2: To define the charging key for online charging in a PCC rule.
Option 3: To identify the User Equipment (UE) in a Policy and Charging Rules Function (PCRF) request.
Option 4: To uniquely identify an Application Detection and Control (ADC) rule within a Traffic Detection Function (TDF) session or predefined rules.
Explanation: The ADC-Rule-Name AVP provides a unique identifier for each ADC rule, crucial for differentiation and application of rules within a TDF session or across predefined rules, as intended by the policy framework.
