Question: In Sponsored Data Connectivity, what triggers the PCRF to generate a monitoring key and request usage monitoring control for the monitoring key?
Option 1: Receipt of ADC Rule provisioning without Sponsor-Identity AVP
Option 2: Receipt of usage thresholds from the AF (Application Function) with sponsor identity
Option 3: Modification of Reporting-Level AVP to SERVICE_IDENTIFIER_LEVEL
Option 4: Update of Charging Key for online charging
Explanation: In Sponsored Data Connectivity, when the PCRF receives usage thresholds from the AF (Application Function) that include sponsor identity information, it uses this sponsor identity to generate a monitoring key. This monitoring key is then used to request usage monitoring control, following specific procedures outlined for managing sponsored connectivity. This process ensures accurate tracking and billing of sponsored data usage.
