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 identification method, device and terminal, which belong to the technical field of communication. The method includes: when a first call request is received in a first serving cell that cannot perform a circuit domain service, redirecting the terminal to a target cell that can perform a circuit domain service; when the stored multiple LAIs do not include the target cell When the LAI is determined, a location update request is sent to the base station where the target cell is located, and multiple LAIs are sent by the base station where the first serving cell is located; when the location update request does not receive a response from the base station where the target cell is located within the first preset time period, And when the time interval at which the base station where the target cell is located instructs the terminal to update the location is greater than the second preset duration or less than the third preset duration, the base station where the target cell is located is determined as a pseudo base station. The invention improves the accuracy of identifying the pseudo base station, thereby preventing the terminal from incorrectly camping on the cell of the pseudo base station, ensuring normal calls to the terminal, and effectively improving the call-through rate.

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...
