Question: In a scenario where Policy and Charging Control (PCC) is enabled, a downlink IP packet within an IP CAN session matches multiple PCC rules with overlapping criteria but these rules have the same precedence. One rule is PCRF-provided, while the other is predefined. Which PCC rule shall be applied to the packet?
Option 1: The predefined PCC rule with the application identifier
Option 2: The PCRF-provided PCC rule with the service data flow filter
Option 3: Both rules are applied sequentially based on their type (filter first, then identifier)
Option 4: In case of a tie in precedence, the packet is silently discarded due to ambiguity
Explanation: According to the specified behavior for handling PCC rules with the same precedence, when a PCRF-provided PCC rule and a predefined PCC rule overlap, the downlink service data flow template of the **PCRF-provided PCC rule** shall be applied. This ensures consistent policy enforcement prioritizing rules directly provided by the Policy Charging Rules Function (PCRF).
