Abstract: Certain embodiments propose to conceal interception from network operators by receiving a setup message to set up a monitoring connection towards another entity (e.g. an ISUP IAM), analyze the received setup message, and responsive thereto, establish the monitoring connection towards the another entity. The control unit is further configured to confirm that a preconfigured identifier representative for a lawful interception is included within the setup message (e.g. inside the field Called Party Subaddress, under Operator ID—octets 4, 5 and 6), and responsive thereto, suppress at least partially a generation of data records for the monitoring connection.

Abstract: Methods, computer program products and apparatuses enabling to conceal lawful interception from network operators by suppressing the generation of the corresponding Call Detailed Record, CDR. The present invention proposes to conceal interception from network operators by receiving a setup message to set up a monitoring connection towards another entity (e.g. an ISUP IAM), analyze the received setup message, and responsive thereto, establish the monitoring connection towards said another entity, wherein the control unit is further configured to confirm that a preconfigured identifier representative for a lawful interception is included within said setup message (e.g. inside the field Called Party Subaddress, under Operator ID—octets 4, 5 and 6), and responsive thereto, suppress at least partially a generation of data records for said monitoring connection.
