Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] Before explaining and describing the embodiments of the present invention in detail, firstly, terms involved in the embodiments of the present invention will be described.

[0047] LA (Location Area, location area): LA refers to a set of cells in the mobile communication system. The function of setting LA is to enable MSC (Mobile Switching Center, mobile switching center) to confirm the location of the terminal in time. When calling a terminal, the MSC only needs to search all cells in the terminal's LA to find the terminal quickly and accurately.

[0048]CSFB (Circuit Switched Domain Fall Back, Circuit Switched Domain Fall Back): CSFB refers to the process that when a terminal resides in a cell where circuit domain services can...

Abstract

The invention discloses a pseudo base station recognition method, a device and a terminal, and belongs to the technical field of the communication. The method comprises the following steps: redirecting the terminal to a target cell capable of performing the circuit domain business when receiving a first call request in a first service cell incapable of performing the circuit domain business; sending a location update request to the located base station of the target cell when multiple stored location area identifiers (LAI) do not comprise the LAI of the target cell, wherein the multiple LAIs are obtained through the sending of the located base station of the first service cell; when receiving a update reject message sent by the located base station of the target cell and the update reject message carries an appointed reason value, determining the located base station of the target cell as the pseudo base station. By use of the recognition method disclosed by the invention, the accuracy of recognizing the pseudo base station can be improved, and then a condition that the subsequent terminal is faulty resided to the cell of the pseudo base station can be avoided, the normal call to the terminal is guaranteed, and the call completion ratio is effectively improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a pseudo base station identification method, device and terminal. Background technique [0002] With the popularization of terminals such as mobile phones, people are more and more accustomed to performing various life-related operations through the terminal, and the terminal usually needs to communicate through the base station of the operator. In some bustling commercial areas, there are often false base stations disguised as operator base stations. Since these false base stations often pretend to be other people's mobile phone numbers and forcefully send spam messages such as fraudulent and advertising promotions to the terminal, in order to protect the data security of the terminal , it is necessary to identify these pseudo base stations that bring troubles to people's lives. [0003] At present, when a terminal receives a call request in an LTE (Long Term Evo...
