Interception and control of ongoing radio connections through interposition and impersonation of a mobile device and cellular radio system

摘要

Taking control of a subscriber terminal is disclosed. An apparatus (114) comprises a processor (116) configured to cause the apparatus (114): to control a stand-alone base station (110) so that an emulated cell (128) of a cellular radio system (100) is formed by transmitting a control channel (134) with information of a real cell (126) and with such transmission power that a subscriber terminal (106) having an ongoing connection (130) with a serving cell (124) base station (102) is caused to measure reception (134) of the stand-alone base station (110) as being better than reception (130) of the serving cell (124) base station (102); and to control the stand-alone base station (110) to perform cell reselection with the subscriber terminal (106) so that the ongoing radio connection (130) with the serving cell (124) base station (102) is transferred to continue with the stand-alone base station (110).
