Question: In a Telecommunication Management context, what is the primary condition for an Application Server or PCEF to provide 'Service Specific Info' (including sub-fields) for Charging Data Records (CDRs)?
Option 1: Only for pre-defined Policy and Charging Control (PCC) rules or Traffic Detection and Filtering (TDF) rules for predefined Application Detection and Control (ADC) rules.
Option 2: For all types of network sessions, regardless of the rule definitions.
Option 3: Exclusively when a User Equipment (UE) initiates a voice call.
Option 4: Solely for data transmissions exceeding a certain threshold.
Explanation: The correct answer is Option 1 because 'Service Specific Info' is provided by an Application Server or PCEF specifically under the condition that it's for pre-defined PCC rules or, in the case of TDF, for pre-defined ADC rules, ensuring specialized charging and management can be applied accurately based on predefined network policies.
