Interception of groups of subscribers
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.
1 . Method for deciding whether to intercept a telecommunications connection wherein, for an identification detail relating to at least one subscriber of the telecommunications connection, a check is made as to whether this identification detail is included in at least one identification detail abbreviation relating to the subscriber to be monitored which is stored in a list, with interception of the telecommunications connection ( 6 ) being initiated if it is stored in the list.
2 . Method according to claim 1 , wherein the identification detail abbreviation is part of a identification detail relating to a mobile subscriber number.
3 . Method in accordance with one of the previous claims, an identification detail abbreviation is part of an e-mail address of a telecommunications subscriber.
4 . Method according to claim 3 , wherein the identification detail abbreviation is a domain name or a part of a domain name in an e-mail address of a telecommunications subscriber.
5 . Method according to claim 1 , wherein an identification detail abbreviation is part of a telecommunications terminal identification (IMEI).
6 . Method wherein the telecommunications connection is routed over a mobile radio network and/or fixed network and/or the Internet.
7 . Method according to claim 1 , wherein the checking is undertaken by equipment of a telecommunications network over which the telecommunications connection is routed or by equipment connected to it.
8 . Method according to claim 1 , wherein the interception is undertaken by official equipment.
9 . Method according to claim 1 , wherein identification details are checked when a connection is set up.
10 . Method according to claim 1 , wherein identification details of telecommunications subscribers are checked on transmission of data packets over a telecommunications connection.
11 . A device for deciding whether to intercept telecommunications connections,
with a list of identification detail abbreviations relating to telecommunications subscribers to be intercepted stored in a memory,
with comparison equipment for comparing identification details transferred over a telecommunications connection relating to subscribers of the telecommunications connection with stored identification detail abbreviations,
with decision equipment to initiate the monitoring of a telecommunications connection with at least one telecommunications subscriber identified as to be monitored by an identification detail abbreviation.
