Embodiment Construction

[0027] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described:

[0028] See figure 1 , the present invention relates to a false base station warning method, and its preferred embodiment comprises the following steps:

[0029] Step S1: automatically scan the frequency of the mobile phone with an invalid SIM card to search for the base station;

[0030] In the present invention, an invalid SIM card refers to a SIM card that cannot be connected to a base station of a regular communication operator, such as a SIM card that has been canceled or reported lost.

[0031] Step S2: Judging whether the base station is found, if yes, execute step S3; if not, execute step S1;

[0032] Step S3: judging whether the base station is successfully connected, if yes, execute step S4; if not, execute step S2;

[0033] Step S4: Determine whether the mobile phone has changed from the offline state to the connected state, if yes, exe...

Abstract

The invention discloses a pseudo base station alarm method and system, and the method comprises the steps: S1, carrying out automatic frequency sweep through a cellphone which is provided with an invalid SIM card, so as to search a base station; S2, judging whether the base station is searched or not: executing step S3 if the base station is searched, or else, executing step S1; S3, judging whether the base station is connected successfully or not: executing step S4 if the base station is connected successfully, or else, executing step S2; S4, judging whether the state of the cellphone is switched to an online state from an offline state or not: executing step S5if the state of the cellphone is switched to the online state from the offline state, or else, executing step S2; S5, determining the base station as a pseudo base station or not, and sending an alarm signal. The method and system can timely find a farer pseudo base station, enlarges the detection range of the pseudo base station, reduces the report leakage, is timely in detection, and is quick in response.

Description

technical field [0001] The invention relates to a false base station alarm method and system. Background technique [0002] "Pseudo base station" is a fake base station, which is generally composed of specific module equipment and a laptop computer. By disguising as an operator's base station, it transmits mobile communication network signals and sends short messages such as fraud and advertising to nearby mobile phones. [0003] A normal short message contains the correct source number, which can trace the source of the short message and prevent impersonation of a public service number, but the source number in the short message sent by a fake base station can also be forged. Numbers, such as 10086 or 95588, make mobile phone users mistakenly believe that they are really text messages sent by mobile companies or ICBC, and carry out illegal and criminal activities such as telecom fraud and advertising sales, causing serious social harm. [0004] The fake base station first ...
