Embodiment Construction

[0117] Figure 1a A wireless communication device 1 of the type to which the present invention is applied as an embodiment is schematically shown. The wireless communication device 1 is shown in a spatial relationship with a cell 7 of a cellular network 6 . In particular, the cellular network supports the Long Term Evolution (LTE) technical standard, ie a wireless communication device supporting this standard can operate with a base station (eNodeB) of the cellular network. The base station 4 provides a counterpart on the air port 3 between the wireless communication device 1 and the cellular network 6 . The base station 4 is further connected to the core network 8 of the cellular network 6, which provides a communication connection to other devices via the Internet or in the same or another cellular network.

[0118] The wireless communication device 1 is equipped with a processing circuit 10 , a transceiver circuit 9 and a connection antenna 2 in this exemplary embodiment. ...

Abstract

The present invention relates to a method for operating a wireless communication device configured to operate in a cellular network comprising a plurality of base stations, the wireless communication device operating in conjunction with a first base station, the method comprising wireless communication Steps of the device: - determine further suitable base stations, in case at least one suitable second base station is found which differs in characteristics from the first base station, - check whether the cell identifier of this second base station is listed in the list from the first base station a list of neighboring cells received by a base station, and - check the signaling power of the second base station, - in case the measured signaling power is significantly higher than the signaling power of the first base station, evaluate the second base station as a false base station , and in case the rating of the second base station as a pseudo base station is higher than a predetermined threshold, the cell identifier of the second base station is not listed in the list of neighboring cells: - remove the second base station from the list of suitable base stations Second base station.

Description

technical field [0001] The invention relates to a method for operating a wireless communication device in a cellular network. [0002] The invention also relates to a wireless communication device using the method. Background technique [0003] In general, in the field of wireless communications according to wireless cellular technology standards such as 3GPP (GSM, UMTS, LTE, etc.), there is a growing problem of illicit behavior by users attempting to exploit the most vulnerable components of wireless communications equipment - Air Interface - Interfering with wireless communications equipment. It is known that those interferences include, inter alia, pseudo base stations (such as IMSI catchers), which pretend that the wireless communication device belongs to a certain cellular network. Thus, instead of providing the service, the IMSI catcher allows recording and locating the wireless communication devices represented by the SIM card (and accordingly their identities). Kn...
