Embodiment 1

[0063] The pseudo base station identification method provided by the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0064] Step 101: Obtain the location update parameter of the user location update event from the Mc interface;

[0065] Here, the location update parameters include at least the LAC and the cell. Specifically, it includes source LAC, source cell, current LAC, and current cell information.

[0066] The Mc interface is an interface between a mobile switching center server (MSC Server) and a media gateway (MGW).

[0067] Step 102: Based on preset rules, using the acquired location update parameters of at least one user, determine the abnormal current cell; and obtain the coordinate information of the abnormal cell;

[0068] Specifically, for each location update parameter, it is judged whether the source LAC in the location update parameter is in the set LAC table; the set LAC table represents all LAC records set by ...

Embodiment 2

[0105] On the basis of the first embodiment, this embodiment describes in detail the identification process of the pseudo base station.

[0106] figure 2 It is the main technical framework of the embodiment of the present invention. combine figure 2 It can be seen that in the embodiment of the present invention, as image 3 As shown, the identification process mainly includes the following steps:

[0107] Step 301: Obtain signaling data of the Mc interface;

[0108]Here, the recognition algorithm mainly involves five fields in the MC interface signaling: event type (eventid), source location area code (OLAC), source cell (oci), current location area code (LAC), current cell ( ci).

[0109] The signaling data whose event type is location update is screened out, so as to obtain the location update parameter from the signaling data of the Mc interface.

[0110] Step 302: using a pseudo base station identification algorithm to identify the pseudo base station, thereby obta...

Embodiment 3

[0160] In order to implement the method of the embodiment of the present invention, this embodiment provides a pseudo base station identification device, such as Figure 6 As shown, the device includes:

[0161] An acquisition unit 61, configured to acquire a location update parameter of a user location update event from the Mc interface; the location update parameter includes at least a location area code LAC and a cell;

[0162] The first determining unit 62 is configured to determine an abnormal current cell by using the acquired location update parameters of at least one user based on a preset rule; and obtain coordinate information of the abnormal cell;

[0163] The second determination unit 63 determines the coordinate information of the pseudo base station by using the coordinate information and the weight of the abnormal cell; the weight of the abnormal cell represents the number of users switched to the abnormal cell within the first preset time period .

[0164] In...

Abstract

The invention discloses a false base station identification method, comprising: obtaining the location update parameters of user location update events from the Mc interface; the location update parameters include at least a location area code (LAC) and a cell; based on preset rules, using the obtained The location update parameters of at least one user determine the abnormal current cell; and obtain the coordinate information of the abnormal cell; use the coordinate information and the weight of the abnormal cell to determine the coordinate information of the pseudo base station; the weight of the abnormal cell Characterizes the number of users switched to the abnormal cell within the first preset time period. The invention also discloses a false base station identification device.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for identifying a false base station. Background technique [0002] Pseudo base station crimes have endangered national communication security, disrupted social public order, and caused huge social harm. [0003] At present, the main pseudo-base station identification schemes are as follows: first, it is necessary to manually judge some characteristics of the pseudo-base station, such as interference location, interference phenomenon, occurrence time, etc.; according to these characteristics, the coverage of the pseudo-base station is initially determined, and then the parameters of the coverage base station are analyzed or actual business behavior to identify pseudo base stations. [0004] However, this method requires a lot of labor costs, and the accuracy of the recognition method is low or the recognition process is complicated and not flexible enoug...
