Question: In the context of PCC using Gx reference point, what is the specific value that the Vendor-ID AVP must be set to when accompanied by an Experimental-Result-Code AVP in a request processing outcome?
Option 1: IETF (1)
Option 2: ETSI (269)
Option 3: IEEE (701)
Option 4: 3GPP (10415)
Explanation: In the Policy and Charging Control (PCC) framework, specifically over the Gx reference point, when utilizing Experimental-Result AVPs to convey the outcome of request processing, it is crucial for interoperability that the Vendor-ID AVP is correctly identified. For specifications aligned with 3GPP standards, setting the Vendor-ID AVP to 10415 (which corresponds to 3GPP) ensures that the Experimental-Result-Code AVP is interpreted within the context of 3GPP-defined values, facilitating seamless communication between network elements. This precise identification is vital for accurate processing and decision-making based on the experimental result codes.
