<p>The invention discloses a method for performing a lawful interception in a packet network. The method comprises the steps of generating (S2) interception related information packets from a communication to be intercepted; generating (S2) communication content packets from a communication to be intercepted; providing (S3) identification data for the interception related information packets and for the communication content packets of one group of communication packets; providing (S5) ordering data for each of the interception related information data packets and for each of the communication content packets; and transmitting (S6) the interception related information packets, the communication packets, the identification data and the ordering data to an interception authority device. By this measure, a missequenced reception of interception related information (IRI) packets and communication content (CC) packets can be avoided. Also, the assembly of IRI packets between corresponding CC packets is possible by a corresponding LEMF of the interception authority.</p> |
