Question: During Lawful Interception (LI) in a 3GPP-compliant telecom network, if a Law Enforcement Agency (LEA) encounters a record with an unrecognized parameter name but recognizable layout, how should the LEA's system handle this situation?
Option 1: Reject the entire record to prevent potential security breaches.
Option 2: Halt processing of all subsequent records until the issue is resolved.
Option 3: Raise an alarm to the network operator's administration center for immediate attention.
Option 4: Ignore the unrecognized parameter and continue processing the rest of the record.
Explanation: According to 3GPP security standards for Lawful Interception, if a parameter's name is not recognized but its layout is (indicating a possible new specification version), the LEA's system should ignore the unrecognized parameter and proceed with processing the rest of the record. This approach minimizes disruptions while allowing for the handling of potentially new, unseen parameters without triggering unnecessary alarms or halting operations.
