Question: In a Policy and Charging Control (PCC) context, when a request is successfully completed between peers, which of the following best describes the type of Result-Code AVP values used to inform the peer?
Option 1: Custom PCC-specific codes defined exclusively in 3GPP TS specifications.
Option 2: A combination of IETF and 3GPP custom codes for broader applicability.
Option 3: Experimental Result-Code AVP values as per IETF RFC guidelines.
Option 4: Result-Code AVP values defined in the Diameter base protocol, as specified by IETF (e.g., RFC 6733).
Explanation: The correct answer is based on the principle of standardization and interoperability in telecom networks. Using Result-Code AVP values from the Diameter base protocol (IETF RFC 6733) ensures consistency across different systems and vendors, facilitating smoother communication between peers in a PCC setup. This approach aligns with the goal of standardized protocols like those defined by 3GPP and IETF, promoting widespread adoption and reducing integration complexities.
