Question: In a Policy and Charging Control (PCC) architecture, under what condition is the authorization of predefined and/or dynamic Application Detection and Control (ADC) rules applicable for a Traffic Detection Function (TDF) session?
Option 1: Only in case of solicited application reporting.
Option 2: Only in case of unsolicited application reporting.
Option 3: In both solicited and unsolicited application reporting scenarios equally.
Option 4: Regardless of the type of application reporting, always applicable.
Explanation: The correct answer is Option 1 because, according to the 3GPP specifications for Policy and Charging Control architecture, ADC Rule authorization is specifically stated to be "only applicable in case of solicited application reporting". This indicates that the decision to activate predefined or dynamic ADC rules for a TDF session, including the selection of parameters for these rules, hinges on this particular scenario. Unsolicited application reporting has a different handling approach, as noted, where all pre-provisioned ADC rules at the TDF are authorized by default.
