Method and radio communication network for securing the SIM card in a mobile station

摘要

The protection method responds to use of a mobile subscriber device in a new radio cell location (NEWC) for paging the subscriber within the previous radio location (OLDC) for indicating fraudulent use of the same subscriber identity module when the subscriber responds to the paging signal. The location of the mobile subscriber and the subscriber identification may be provided in response to the received paging signal, evaluated for indicating fraud, or for updating the actual subscriber location.
