Embodiment 1

[0021] see figure 1 , figure 1 It is a schematic flowchart of a method for locating a pseudo base station in Embodiment 1 of the present invention. The specific steps are:

[0022] Step 101, the positioning system acquires a measurement report of the GSM network within a first preset time.

[0023] When obtaining the measurement report, collect the measurement report through the Abis interface or collect the measurement report through the measurement report data collection interface of the base station controller. In specific implementation, it may also be a measurement report collected by any means and reported by the terminal, which is not limited in the specific embodiment of the present invention.

[0024] The Abis interface is defined as the interface between the Base Station Controller (BSC) and the Base Transceiver Station (BTS).

[0025] The measurement report reported by the terminal is the measurement result data packet of each neighboring cell, which specificall...

Embodiment 2

[0043] see figure 2 , figure 2 It is a schematic flowchart of a method for locating a pseudo base station in Embodiment 2 of the present invention. The specific steps are:

[0044] In step 201, the positioning system acquires location update signaling reported by terminals within a second preset time period, and determines that the location update signaling is an unexpected location update event according to preset rules.

[0045] In this step, the location update signaling includes the original location area code, the new location area code and the cell identification code.

[0046] In specific implementation, the location update process of the update type on the A interface in the second preset period is obtained (Location updating type: Normal location updating), and combined with the Abis signaling, each location update signaling is analyzed. The A interface is defined as the interface between the network subsystem (NSS) and the base station subsystem (BSS), that is, ...

Abstract

The invention discloses a pseudo base station positioning method, comprising steps of obtaining a measurement report of a GSM network in first preset time, screening out the measurement report of an adjacent area the measurement result of which is abnormal, performing analysis and statistics on the measurement reports screened out, determining geographic location areas where suspected pseudo base stations are positioned, BCCH frequency points of the suspected base pseudo base stations and identification codes of the base stations, following and positioning the pseudo base stations step by step in the determined geographic location areas where the suspected pseudo base station are positioned. The pseudo base station positioning method can position the pseudo base station quickly and accurately.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a pseudo base station positioning method. Background technique [0002] In the cellular mobile communication system, the terminal searches for signals of surrounding cells in idle mode, and selects a cell to camp on according to the signal strength of each cell. Each cell broadcasts the location area to which the cell belongs in the system broadcast message. When the cell the terminal chooses to camp on belongs to a new location area, the terminal initiates a location update process and reports the location area number the terminal previously camped on to the The internet. [0003] In the Global System for Mobile Communications (GSM) cellular mobile communication system, the terminal uploads a measurement report to the base station in the connection mode, and the measurement report includes the downlink signal strength of the current serving cell of the terminal, one or ...
