Question: When a TDF detects the start/stop of an application's traffic matching an ADC Rule provided by the PCRF via the Sd interface, under what condition will it NOT report this information to the PCRF?
Option 1: If the PCRF has not subscribed to the APPLICATION_START/APPLICATION_STOP Event-Triggers.
Option 2: If the detected application's traffic does not match any ADC Rule.
Option 3: If a request to mute such a notification (Mute-Notification AVP) is part of the corresponding ADC Rule.
Option 4: If no enforcement actions are defined within the corresponding ADC Rule.
Explanation: According to the specified behavior, if a Mute-Notification Attribute Value Pair (AVP) is included in the ADC Rule, it instructs the TDF not to send a notification to the PCRF upon detecting the start/stop of the application's traffic, even if the PCRF had previously subscribed to such event triggers. This condition directly impacts the reporting behavior of the TDF to the PCRF.
