Problems solved by technology

[0003] However, the existing GSM (Global System for Mobile Communication, Global System for Mobile Communications) mobile communication system has the defect of one-way authentication, that is, only the network authenticates the terminal, and the terminal cannot identify the legality of the network identity. Base station, when users connect to the network, the security is low, and they are vulnerable to the intrusion of fake base stations

Embodiment 1

[0060] The present invention provides a pseudo base station identification method for terminals, see figure 2 as shown, figure 2 A flow chart of the process of a pseudo base station identification method provided by the present invention; the method includes:

[0061] Step s101: After the terminal reselects the base station cell, it receives the system information sent by the reselected base station cell;

[0062] Step s102: sending a location update request to the cell of the base station;

[0063] Step s103: According to the system information, it is judged whether the cell of the base station satisfies the judging criteria of the pseudo base station, and if so, proceed to step s104;

[0064] Step s104: After receiving the identity request information sent by the base station cell, send false identity information to the base station cell;

[0065] Step s105: Determine whether the identity request information sent by the base station cell continues to be received, and if...

Embodiment 2

[0068] Based on the first embodiment, the present invention also provides another pseudo base station identification method. see image 3 as shown, image 3 A flow chart of the process of another pseudo base station identification method provided by the present invention; the method includes:

[0069] Step s101: After the terminal reselects the base station cell, it receives the system information sent by the reselected base station cell;

[0070] The terminal here is a mobile phone or a tablet computer, etc., of course, the present invention is not limited thereto.

[0071] Pseudo base stations generally work in the GSM900 frequency band and only have one GSM frequency point, that is, only one base station cell. The pseudo base station can change its own frequency point to the current network frequency point, and can adjust its own transmission power at the same time. Since the terminal has been measuring the signals of the neighboring cells in the idle state, when the sig...

Abstract

The invention discloses a method and a system for recognizing a pseudo base station, which are used in a terminal. When base station cell reselection happens to the terminal, system information sent by a base station cell after reselection is received; a position updating request is sent to the base station cell; according to the system information, whether the base station cell meets a pseudo base station judging criterion is judged, and if yes, after identity request information sent by the base station cell is received, false identity information is sent to the base station cell; whether the identity request information sent by the base station cell is received continuously is judged, and if yes, the address of the base station cell is marked as pseudo base station; and another base station cell is reselected by the terminal. The pseudo base station can be recognized, information leakage of the terminal user during the recognition process can be avoided, and the network security of the terminal user is greatly ensured. The invention also provides a terminal comprising the above pseudo base station recognition system. The terminal also has the above beneficial effects which are not described any more.

Description

technical field [0001] The invention relates to the technical field of GSM communication, in particular to a pseudo base station identification method and system. The invention also relates to a terminal. Background technique [0002] The fake base station is a base station of a public mobile operator forged by criminals. The fake base station attracts mobile phone users around by forging some network parameters and increasing its own transmission power. When the mobile phone user successfully resides in the fake base station, the fake base station can obtain the mobile phone user identity information, and then carry out a large volume of illegal information transmission, and then obtain illegal profits from it. see figure 1 as shown, figure 1 Flowchart of the process of working for the current pseudo base station. [0003] However, the existing GSM (Global System for Mobile Communication, Global System for Mobile Communications) mobile communication system has the defec...
