Pseudo base station identification method and device

Abstract

The embodiment of the invention discloses a pseudo base station identification method. The method comprises the steps of receiving a measuring result reported by UE (User Equipment), wherein the measuring result comprises a frequency point, a cell identifier and global cell identification code information; searching whether the matched frequency point, cell identifier and global cell identification code information in the measuring result exist in a pre-stored legal base station background network management database or not; and determining a base station corresponding to the frequency point, cell identifier and global cell identification code information to be a pseudo base station if the completely matched frequency point, cell identifier and global cell identification code information cannot be searched in the pre-stored legal base station background network management database. The embodiment of the invention also provides a pseudo base station identification device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for identifying a pseudo base station. Background technique [0002] At present, according to the strength of the pilot signal transmitted by the base station, the terminal selects a signal with a strong signal for connection. In the prior art scheme of connecting according to the strength of the signal transmitted by the base station, when the pseudo base station transmits a strong signal, it is easy for the terminal to select the pseudo base station for connection and disconnect the previously connected legal base station. [0003] During the authentication process between the terminal and the fake base station, it is easy to cause the terminal's International Mobile Subscriber Identification Number (IMSI) to be intercepted by the fake base station, and the fake base station will send corresponding fraudulent text messages to the terminal, cau...

In the prior art scheme of connecting based on the signal strength of the base station, when the pseudo base station transmits a strong signal, it is easy for the terminal to choose the pseudo base station for connection, and disconnect the previously connected legal base station

[0003] During the authentication process between the terminal and the fake base station, it is easy to cause the terminal's International Mobile Subscriber Identification Number (IMSI) to be intercepted by the fake base station, and the fake base station will send corresponding fraudulent text messages to the terminal, causing the user to believe the fraud SMS causes certain losses to users
