Problems solved by technology

However, fake base stations may use other users' numbers to send short messages, so in many cases the sending number cannot be used as a reference for identification
And according to short message content keywords and short message center number are not accurate
Moreover, the current pseudo-base station identification schemes are basically passive identification. Only when the user is trapped in a pseudo-base station can it be detected whether the current pseudo-base station is a pseudo-base station. There is no active method for detecting a pseudo-base station.

Embodiment 1

[0057] refer to figure 1 As shown, it is a flowchart of a method for detecting a specified type of cell provided by Embodiment 1 of the present invention. The technical solution of this embodiment is applicable to the situation of detecting and searching for a specified type of cell. Wherein, the specified type of cell may be any cell with a specific configuration, typically such as a pseudo base station cell around the current environment. Before detection, all frequency points around the current environment are searched to obtain all signal cells around the current environment, so as to detect a specified type of cell from all signal cells. The method can be executed by a device for detecting cells of a specified type, and the device can be implemented in software and / or hardware, and configured to be executed in a communication terminal.

[0058] A kind of detection method of specified type sub-district provided by the present invention, the steps of this method are as fol...

Embodiment approach 1

[0063] To sum up, according to the configuration parameters in the received cell system information, a cell of a suspected designated type can be obtained through different implementation methods, and the preferred implementation mode 1 here specifically includes:

[0064] S1110. Receive system information of all signal cells around the current location to obtain configuration parameters of the signal cells, where the configuration parameters at least include public land mobile communication network identifiers and location area identifiers.

[0065] As mentioned above, after the detection device searches the surrounding environment and finds all the cells with signals, then the detection device can read the system information of all the cells with signals. Therefore, it is necessary to obtain the parameters of the cell from the system information, and judge whether the cell is a suspected specified type of cell in the subsequent steps according to the cell parameters. Here, t...

Embodiment approach 2

[0072] According to the configuration parameters in the received cell system message, different implementations can be used to obtain the suspected specified type of cell, and the second preferred implementation here specifically includes:

[0073] S1120. Receive the cell signal strength values ​​and system information of all signal cells around the current location, and set the received cell signal strength values ​​to be the same, and acquire configuration parameters in the system information, wherein the configuration parameters include Reselect parameters.

[0074] As mentioned above, after the detection device searches the surrounding environment, it finds out all the cells with signal, then the detection device detects the cell signal strength values ​​(RLA_C) of all the cells with signal, here, the cells of different cells with signal The signal strength values ​​are not exactly the same. In order to facilitate the reselection evaluation of different cells, here, the ce...

Abstract

The invention discloses a specified type cell detection method, a specified type cell detection device and a communication terminal. The specified type cell detection method comprises the steps of: acquiring a suspected specified type cell according to configuration parameters in a received cell system message; and residing in the suspected specified type cell, and confirming whether the suspected specified type cell is a specified type cell according to communication state of the communication terminal in the suspected specified type cell. The specified type cell detection method, the specified type cell detection device and the communication terminal provided by the invention can judge all suspected specified type cells surrounding the current environment quickly and accurately, detect the specified type cell out from the suspected specified type cells quickly, and have the advantages of being able to achieve detection of the specified type cell and preventing a user from being caught in the specified type cell simply, quickly and accurately.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and communication terminal for detecting a specified type of cell. Background technique [0002] A fake base station is a fake base station, which is a high-tech instrument, generally composed of a host computer and a laptop computer. By disguising itself as an operator's base station, modifying the configuration of the base station allows the surrounding terminals to reside in the fake base station, and arbitrarily using other people's or enterprise mobile phones number (you can choose a number with a better ending number, or use a number with a ending number of 10086 or 95588, so that mobile phone users mistakenly believe that it is really a text message sent by a mobile company or Industrial and Commercial Bank of China), and forcibly send fraudulent, advertising, etc. to the user's mobile phone Text Message. [0003] The pseudo-base station modi...
