Problems solved by technology

The identification of pseudo base stations is usually carried out during the access process of the mobile terminal. This method of checking the operator database usually takes a long time because of the large amount of data in the operator database, which affects the access speed of the mobile terminal. , thereby reducing the user experience of using mobile terminals

Embodiment 1

[0034] see figure 1 A flow chart of a base station discrimination method is shown, the method is applied to a mobile terminal, that is, it is described from the description of the mobile terminal side as an example, and includes the following steps:

[0035] Step S102, acquiring the current location information of the mobile terminal and positioning parameters of the target base station, the positioning parameters include: LAC (Location Area Code, location area code) and / or CID (Cell_ID, cell identification code).

[0036]In practical applications, the current location information of the mobile terminal can be determined according to the GPS (Global Positioning System) positioning signal of the mobile terminal, and the broadcast signal of the BCCH (Broadcast Control Channel, broadcast control channel) system of the cell where the target base station is located Determine the positioning parameters of the target base station. Usually a base station can be divided into one or mo...

Embodiment 2

[0047] On the basis of the foregoing examples, see figure 2 The flow chart of another base station discrimination method shown specifically includes the following steps:

[0048] Step S202, acquiring the current location information of the mobile terminal and positioning parameters of the target base station, where the positioning parameters include: LAC and / or CID.

[0049] Step S204, searching for the boundary range of legal positioning parameters corresponding to the location information.

[0050] This embodiment provides a method of setting the boundary range, that is, according to the base station positioning parameters included in the operator database, the boundary range of the legal positioning parameters of the specified area is set locally in the mobile terminal; wherein the specified area includes the location information corresponding to area.

[0051] Step S206, judge whether the positioning parameter of the target base station is within the boundary range, if ...

Embodiment 3

[0072] For the base station identification method provided in the foregoing embodiments, the embodiment of the present invention provides a base station identification device set on the mobile terminal side, see Figure 4 A structural block diagram of a base station discrimination device shown, the device includes the following modules:

[0073] An information acquisition module 402, configured to acquire the current location information of the mobile terminal and the positioning parameters of the target base station, where the positioning parameters include: LAC and / or CID;

[0074] A range search module 404, configured to find the boundary range of legal positioning parameters corresponding to the location information;

[0075] A parameter judging module 406, configured to judge whether the positioning parameters of the target base station are within the boundary range;

[0076] Index setting module 408, when the judging result of the judging module is that the positioning ...

Abstract

The present invention provides a base station discrimination method, device and mobile terminal, which relate to the field of communication technology. The method includes: obtaining the current position information of the mobile terminal and positioning parameters of the target base station, the positioning parameters including: LAC and / or CID; finding the position The boundary range of legal positioning parameters corresponding to the information; determine whether the positioning parameters of the target base station are within the boundary range; if not, set the risk index of the positioning parameters to be greater than 0; determine the authenticity of the target base station according to the risk index of the positioning parameters. The present invention does not need to search the positioning parameters of the target base station from the legal positioning parameters with a large amount of data, but only needs to judge whether the positioning parameters are within the boundary range of the legal positioning parameters, and then can give the corresponding risk index, which improves the efficiency of setting the positioning parameters The accuracy and efficiency of the risk index further improves the efficiency of the mobile terminal in discriminating the authenticity of the base station, and effectively speeds up the access speed of the mobile terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a base station discrimination method, device and mobile terminal. Background technique [0002] Mobile terminals (such as mobile phones) have become more and more integrated into people's daily life. People can not only use mobile terminals to communicate, but also use mobile terminals to conduct electronic payment or surf the Internet. Based on this, mobile terminals are directly related to people in the process of use. information security and property security. [0003] However, lawbreakers will build their own fake base stations to attract mobile terminals to attach, so as to send advertisements and fraudulent messages to mobile terminals through fake base stations. They can also use fake base stations to obtain information about mobile terminals and affect the normal operation of mobile terminals. Communication greatly threatens people's information and pro...
