Question: How is the Presence-Reporting-Area-Identifier AVP (AVP code 2821) encoded in a Policy and Charging Control (PCC) context for 3GPP-EPS access type?
Option 1: ASCII Encoding with Decimal Representation
Option 2: Binary Encoding with Octal Representation
Option 3: Full Hexadecimal Representation (Binary, not ASCII encoding)
Option 4: URL Encoding with Base64 Representation
Explanation: In the context of Policy and Charging Control for 3GPP-EPS access type, precise encoding is crucial for accurate location and presence reporting. The correct answer, Full Hexadecimal Representation (Binary, not ASCII encoding), ensures that the Presence-Reporting-Area-Identifier AVP is encoded in a manner that maintains its integrity and readability across different systems, which is vital for managing user equipment's (UE) entry or exit from specific presence reporting areas within telecom networks. This encoding method supports efficient processing of location updates and presence reports, aligning with the technical requirements for seamless communication services.
