Problems solved by technology

[0006] The current false base station detection technology can only be detected when the mobile terminal is connected to the false base station. The disadvantage is that the detection is not timely and the interference of spam messages cannot be completely avoided.

Embodiment 1

[0041] Such as figure 1 As shown, a pseudo base station identification method mainly includes the following steps:

[0042] S01, monitor the broadcast information of the base station, and analyze the RXLEV-ACCESS-MIN information of each base station.

[0043] S02. When the RXLEV-ACCESS-MIN information of a base station does not meet the preset integer value, determine that the base station is a pseudo base station. Generally, the RXLEV-ACCESS-MIN information (minimum access power) of a true base station is a confirmed integer value, such as -101db, so the RXLEV-ACCESS-MIN information of a true base station can be preset based on experience. However, the pseudo base station does not meet the preset integer value, which is generally an interval such as less than -110db. This method can identify the pseudo base station only by analyzing the broadcast, so the scheme can judge the existence of the pseudo base station before the mobile terminal is connected to the pseudo base stat...

Embodiment 2

[0045] In order to further improve the accuracy of false base station detection, other characteristics of the base station can also be used to detect the false base station. For example, the LACs of real base stations are very regular, and the LAC values ​​of real base stations in adjacent cells are relatively close, while the LAC values ​​of pseudo base stations are quite different.

[0046] Specifically, such as figure 2 As shown, a pseudo base station identification method mainly includes the following steps:

[0047] S01A, monitor the broadcast information of the base station, and analyze the RXLEV-ACCESS-MIN information and LAC information of each base station.

[0048] S02A. Set the relevant information of base stations whose RXLEV-ACCESS-MIN information is a preset integer value in the second base station list, otherwise set in the first base station list. The relevant information of the base station includes base station RXLEV-ACCESS-MIN information, LAC information...

Embodiment 3

[0062] On the other hand, if image 3 As shown, the present invention discloses a pseudo-base station identification device, which mainly includes a monitoring analysis module 10 and a judgment module 20 connected to each other, wherein:

[0063] The monitoring analysis module 10 is used to monitor the broadcast information of the base station, and analyze the RXLEV-ACCESS-MIN information of each base station;

[0064] The judging module 20 is used for judging that the base station is a pseudo base station when the RXLEV-ACCESS-MIN information of the base station does not meet the preset integer value.

Abstract

The invention provides a pseudo base station detection method. The pseudo base station detection method comprises the steps of: monitoring broadcast information of base stations, and analyzing RXLEV-ACCESS-MIN information of various base stations; and, when the RXLEV-ACCESS-MIN information of a base station does not satisfy a pre-set integer value, judging that the base station is the pseudo basestation. According to the scheme, existence of the pseudo base station can be judged before a mobile terminal and the pseudo base station are connected; and thus, the method has the characteristics ofbeing timely to detect, high in accuracy rate, low in cost and wide in application range. The invention further discloses a pseudo base station detection device and system, and a communication server.

Description

technical field [0001] The present invention relates to the technical field of electronic information, in particular to a pseudo base station identification method, device, system and a communication server. Background technique [0002] Because the 2G communication network adopts one-way authentication, that is, only the 2G base station authenticates the mobile terminal, but the mobile terminal does not authenticate the 2G base station, so the criminals use this defect to connect the mobile terminal to the fake base station to send the mobile terminal Sending spam text messages and even conducting fraudulent activities have greatly affected the lives of users. Although the 4G communication network adopts a two-way authentication method, which can effectively prevent mobile terminals from connecting to pseudo base stations, all current 4G mobile phones support 2G communication networks. As long as the 4G communication network is interfered, the network of mobile terminals wi...
