Detection and protection mechanism for fake relay station in telecommunication network

Abstract

A detection and protection system for fake relay stations in a telecommunication network comprises a core network, which comprises a threat detection device comprising a radio terminal and a processor; and a plurality of signal relay stations, wherein the radio terminal is communicated with the signal relay stations, the threat detection device performs a wireless signal scanning, and the processor identifies the signal relay stations according to a result of the wireless signal scanning and judges whether there are fake relay stations among the signal relay stations; wherein, the processor decodes the information in the result of the wireless signal scanning, compares the identification information of each signal relay station in the information with a white list, so as to identify whether the signal relay stations include fake relay stations which do not belong to the white list, wherein the white list contains the identification information of legitimate relay stations; and wherein in case that the fake relay stations are identified, the processor sends out an alarming message.
