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...
