Question: What action does the Policy and Charging Rules Function (PCRF) take if it determines a received CC-Request has timed out based on the Origination-Time-Stamp AVP and Maximum-Wait-Time AVP?
Option 1: The PCRF will queue the request for further evaluation to ensure no other checks are pending.
Option 2: The PCRF rejects the CC-Request by setting the Experimental-Result-Code to DIAMETER_ERROR_TIMED_OUT_REQUEST.
Option 3: The PCRF ignores the timeout and processes the CC-Request as if it were still valid.
Option 4: The PCRF sends a notification to the originating entity to reinitiate the request with updated timestamps.
Explanation: This is because, according to the specified telecom protocol behavior, when the PCRF identifies a CC-Request as timed out (based on the provided timestamps), it should reject the request. The rejection is specifically done by setting the Experimental-Result-Code to DIAMETER_ERROR_TIMED_OUT_REQUEST, ensuring clear communication of the reason for rejection back through the network, maintaining efficiency and preventing stale requests from being unnecessarily processed.
