Process and device to identify a mobile user in a digital cellular mobile radio

摘要

The invention relates to a method and a simulator for identifying and/or tapping a mobile terminal in a digital 5 cellular mobile radio network, in which data is transmitted according to a code multiplex method. The aim of the invention is to enable a terminal to be identified in a mobile radio network, in which data is transmitted according to a code multiplex method and if required to 10 enable the tapping of conversations that are conducted via the mobile telephone. To achieve this: a simulator is positioned in close proximity to the terminal to be identified; the parameters that are relevant to the data transmission of base stations in the mobile radio network 15 that are in close proximity to the simulator are determined by a measuring system and are transferred to the simulator; the simulator is operated as a new base station, taking into consideration the determined parameters, but having another location area code; the 20 terminal to be identified recognizes the simulator as a new base station and logs on to said station using its identification parameters; the terminal is identified by means of the transmitted identification parameters; after identification, the terminal is redirected to a GSM mobile 25 radio network. 35235461 (GHMatters) P90955.AU 31/07/12 -V) 0: CN m
