Problems solved by technology

Since IRI packets and CC packets are sent to the LEA through logically separate connections, and the number of CC and IRI packets is generally not 1:1, it is difficult to effectively correlate the two packets
Therefore, if such delays and misordering of IRI and / or CC packets occur in the LI, then this will cause serious problems, since instead of getting these packets in an easily recognizable order from the first possible location Putting these groups into the correct order afterwards is a much more complex task than

Embodiment Construction

[0054] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to these drawings.

[0055] figure 1 A network system that can implement this embodiment is shown. because figure 1 It has already been described in the Introduction, so unnecessary repetition is omitted here. However, it should be noted that according to this embodiment, some modifications are made to the intercepting node (ie GSN 3) and LEA 1, as described later.

[0056] According to the present invention, IRI packets (relating to intercepted packet-switched or circuit-switched communications) are numbered, for example starting from 0 and incremented by 1 on a packet-by-packet basis. Likewise, CC packets related to a certain communication session (eg PDP context in GPRS) are also numbered. Then, the IRI packets IRI0, IRI1, IRI2, . The actual communication content (CC) data can be obtained in the correct order. The same applies to CC groups CC0, CC1, CC2, . . ...

Abstract

The invention discloses a method for performing a lawful interception in a packet network. The method comprises the steps of generating interception related information packets from a communication to be intercepted; generating communication content packets from a communication to be intercepted; providing identification data for the interception related information packets and for the communication content packets of one group of communication packets; providing ordering data for each of the interception related information data packets and for each of the communication content packets; and transmitting 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.

Description

technical field [0001] The present invention relates to a method and system for performing legal interception in a packet network. Background technique [0002] Statutory interception is a requirement of national law and it is usually mandatory. Sometimes, network operators and / or service providers are required to provide interception results related to specific identities to specific interception management agencies or law enforcement agencies (LEAs) in accordance with statutory authority. [0003] Interception has various aspects. The laws of each country stipulate in what circumstances and under what constraints interception can be carried out. If the LEA wants to use statutory interception as a means, then a statutory authority, such as a license, can be requested from the inspector or other responsible person. If legal rights are granted, the LEA may present its legal rights to the access provider (which provides access from the user terminal to the network), to the ...
