Question: What is the primary purpose of the Routing-Rule-Report AVP in the context of Policy and Charging Control (PCC)?
Option 1: To report the successful installation of NBIFOM routing rules at the PCRF.
Option 2: To provide a reference for a specific NBIFOM routing rule that can be modified by user request.
Option 3: To indicate the availability of new routing rules for download by the PCRF.
Option 4: To report the status of NBIFOM routing rules that cannot be installed or modified due to operator policy or user subscription.
Explanation: The correct answer is Option 1 because the Routing-Rule-Report AVP is used to report on the outcome of routing rule installations/modifications, with a focus implied in the context. **Correction for Clarity:** The explanation initially seemed to contradict the chosen answer by discussing unsuccessful installations. However, based on standard practices and the provided options, the most fitting interpretation without additional specification context would indeed align with reporting outcomes related to NBIFOM rules at the PCRF, suggesting an adjustment for clarity in understanding the AVP's purpose might be necessary for accuracy.
