Question: In a PCC architecture supporting Rule Versioning, what is the expected behavior of the PCRF when modifying a PCC rule that had a content version assigned?
Option 1: The PCRF updates the existing content version without re-sending the entire rule content.
Option 2: The PCRF assigns a new content version but only sends the modified parts of the rule to the PCEF.
Option 3: The PCRF ignores content versioning for subsequent modifications if the previous version was successfully installed.
Option 4: The PCRF assigns a new, unique content version and includes all related content for the PCC rule in the update.
Explanation: This is because when RuleVersioning is supported and a PCC rule is modified with an assigned content version, the PCRF must assign a new content version. To ensure proper installation, all content related to that PCC rule must be included with each modification, making Option 4 correct. This ensures the PCEF has the complete and latest information for the rule, aligning with ensuring proper rule installation in telecom networks.
