Abstract: The invention relates to a method for lawful interception in the case of call forwarding (AW_TlnB) in a packet-oriented telecommunications network (TK1, TK2, TK3), in which switching functions (S-CSCF1, . . . , P-CSCF3) are made available by servers. The additional aim in this telecommunications network (TK1) is to monitor connections of a subscriber (Tln B) with call forwarding (AW_TlnB) by means of lawful interception. In this case, monitoring (ÜW_TlnB) of the connections of the subscriber (Tln B) is notified to a first switching function (S-CSCF1) which is responsible for a called subscriber (Tln B) with call forwarding (AW_TlnB). The first switching function (S-CSCF1) then writes (23) a tag for said subscriber (Tln B) to a predetermined parameter of a switching protocol. Only then is signalling of call forwarding (AW-TlnB) carried out to a second switching function (S-CSCF2) which is responsible for a calling subscriber (Tln A) and the connection is then forwarded to a third switching function (S-CSCF3).

Abstract: In a packet-switching and/or cell-switching communication network which comprises a plurality of switching nodes and in which the individual switching nodes in the communication network are each allocated a unique identification, eavesdropping measures are provided in order to eavesdrop on at least one data link that has been formed between two communication subscribers, in which case one of the two communication subscribers is identified by means of at least one eavesdropping measure as a communication subscriber to be eavesdropped on. The switching nodes which are intended for activation of eavesdropping measures are each allocated at least one activation database which has the identifications of the switching nodes which are enabled for activation of further eavesdropping measures.

Abstract: The invention relates to a gas-insulated bus bar component comprising a grounded housing that is filled with protective gas and at least one bus bar conductor, which extends in the longitudinal direction of the housing and is supported on said housing by means of insulating bus bar supports. According to the invention, each bus bar conductor is connected to a disconnecting switch that is insulated by protective gas. The aim of the invention is to provide a component of this type, which can be simply connected to and disconnected from an air-insulated conductor, even when operational. To achieve this, the disconnecting switch is located in an outdoor bushing that is fixed to the housing.

Abstract: Disclosed are a particularly efficient and resource-saving method and device for intercepting at least one user of a communication terminal in a communication network. The invention is characterized in that a central interception and evaluation unit (BAA) receives service data of at least one communication terminal (MS), said received service data is evaluated according to at least one predefined filtering criterion, and at least one evaluation result is forwarded to another network unit (LEA).

Abstract: An improved surveillance of subscribers of a mobile radio network by a monitoring center is made possible by a method for monitoring a subscriber of a mobile radio network. According to this method, a switching facility requests location data from a subscriber location data service facility, and after obtaining location data, sends this data in a in a monitoring information packet to a montioring center.

Abstract: An efficient decision of the necessity of an authority to intercept telecommunications connections is made possible by a method for deciding to intercept a telecommunications connection during which it is verified whether an identification detail concerning at least one subscriber of the telecommunications connection is contained in at least one identification detail abbreviation, which concerns the subscriber to be monitored and which is stored in a list. In the event this identification detail is contained in the list, an interception of the telecommunications connection is initiated.

Abstract: An efficient and reliable monitoring of users of a telecommunication network is achieved by means of a method for the monitoring of a telecommunication user's data transmitted by a telecommunication network (4). Copies of the data are transmitted to at least one listening station (LEA 6;7;8;9), whereby the data is sent from an exchange device (VSGSN; HSGSN etc.), as a copy, to a monitoring handling device (CIH 14) and sent from said device (CIH 14) to one (7) of a number of addresses of listening stations (LEA 7;8;9) known thereto (CIH 14).
