Problems solved by technology

[0008] Defect: Often the location data is directly reported to the terminal, it will not be uploaded to the positioning platform, and cannot be used by the technical investigation system
[0011] Disadvantage: Active positioning must know the mobile phone number in advance, otherwise it cannot be located, so it is not suitable for technical investigation systems
[0014] Defect: It can be used by the technical investigation system, but the fake base station will interfere with the normal network of the mobile operator and make the terminal break away from the operator's network

Embodiment Construction

[0040] The embodiment of the present invention adopts passive positioning. The principle of passive positioning is: when a terminal uses a mobile communication network, the network needs to advise the terminal from which base station to obtain services, and the terminal will also report its own location to the network so that it can be found when called. During this process, a large amount of location data related to the location of the terminals will be generated. By recording and analyzing the location data, the locations of all terminals in the network can be known.

[0041] The use of passive positioning can eliminate the need to specify the terminal ID in advance. As long as the terminal is connected to the wireless communication network, the location data related to the terminal location will be generated. By continuously collecting the location data of the terminal on the network of the operator, it can be a technology based on passive positioning. The investigation syst...

Abstract

The present invention discloses a technical investigation method and system based on passive positioning. The technical investigation system acquires terminal positioning data by adopting passive positioning, performs distributed cache for the terminal positioning data, performs unified storage for the cached terminal positioning data, analyzes behavior characteristics of a terminal by utilizing the unified-stored terminal positioning data, and outputs a terminal identify (ID) of a suspected terminal according to the analysis result, thereby finding out possible suspects.

Description

technical field [0001] The invention relates to the technical investigation field, in particular to a passive positioning-based technical investigation method and system. Background technique [0002] Wireless device positioning usually has the following means: [0003] 1. GPS positioning: [0004] GPS (Global Positioning System) is the global positioning system, which is a satellite navigation and positioning system developed by the United States. [0005] The GPS system includes 24 GPS working satellites, and these GPS working satellites together form the GPS satellite constellation. Each GPS working satellite sends out a signal for navigation and positioning. It is these signals that GPS users use to do their work. [0006] The user part of GPS is composed of GPS receiver, data processing software and corresponding user equipment, such as computer meteorological instruments and so on. The role of the user part is to receive signals sent by GPS satellites, and use the...
