N-to-N protocol data unit acknowledgment mechanism for improving interception data reliability

In a 5G telecommunications mobile network, a system for improving data reliability of a lawful interception network interface via n-to-n acknowledgments, comprising:

• a processing system comprising a processor;
• and
• a computer memory comprising instructions that, when executed by the processing system, cause the system to perform operations comprising:
• based on receiving a protocol data unit (PDU) from a point of interception (POI) application, starting a PDU receipt timer having a first duration;
• generating a sequence number list of PDU sequence numbers based on identifying PDU sequence numbers from PDUs received from the POI application during the first duration of the PDU receipt timer;
• and
• providing, to the POI application, a PDU acknowledgment packet that includes the sequence number list of PDU sequence numbers from the PDUs received during the first duration of the PDU receipt timer.

A computer-implemented method for improving data reliability of a lawful interception network interface within a telecommunications mobile network via n-to-n acknowledgments, comprising:

• based on receiving a protocol data unit (PDU) from a point of interception (POI) application, starting a PDU receipt timer having a first duration;
• generating a sequence number list of PDU sequence numbers based on identifying PDU sequence numbers from PDUs received from the POI application during the first duration of the PDU receipt timer;
• and
• providing, to the POI application, a PDU acknowledgment packet that includes the sequence number list of PDU sequence numbers from the PDUs received during the first duration of the PDU receipt timer,
• wherein providing the PDU acknowledgement packet including the sequence number list of PDU sequence numbers to the POI application further causes the POI application to perform one or more actions with one or more PDUs from the set of PDUs.
