Mobile terminal detection method and system based on software radio

Abstract

Aiming at defects of the conventional mobile terminal detection, the invention provides a mobile terminal detection method and system. The method comprises the following five steps: configuring a system, obtaining the information of a base station, constructing a pseudo base station, monitoring uplink signaling of a mobile terminal and recognizing the uplink signaling of the mobile terminal; the mobile terminal detection system comprises a radio frequency unit, an intermediate frequency unit, a base band processing unit and a control unit which are sequentially connected in series. The mobile terminal detection method and system have the technical effects as follows: a hardware platform shared by both a GSM module and a CDMA module is used, the processing control of the radio frequency, the intermediate frequency and the base band is completed through the control unit, and the GSM and CDMA parameter selection is completed through the control unit, so that the system structure is simplified, and the great convenience in carrying and layout is achieved. According to the invention, a three-passageway mode is adopted, the pseudo base station is adopted to send a signal to induce a mobile phone to send a message, thus, the capturing and detection of identity information of a target can be completed, and a high speed and high accuracy are achieved.

Description

technical field [0001] The invention belongs to the technical field of communication monitoring, and in particular relates to a mobile terminal detection system and detection method.

Problems solved by technology

[0011] The above detection methods all have deficiencies and cannot meet the detection requirements of large-scale, high-speed, high-precision, and high-efficiency mobile terminals. The specific performance is as follows:

[0012] (1) The service base station and network detection method require the help of the operator, the operation process is complicated, and the coordination workload is heavy. For small-scale mobile detection such as conference rooms, it cannot be accurately completed, and it is easy to cause the leakage of mission objectives and content;

[0013] (2) In the traditional third-party mobile terminal detection method, it is only for the detection of a single network user, and cannot complete the detection of multiple network mobile terminals, which is not suitable for actual use;

[0014] (3) The existing moving target detection systems are all independent, that is, each moving target detection system is composed of independent radio frequency units, baseband units and control units, which makes the system large in size and high in cost. Not suitable for miniaturized application scenarios

In addition, since the radio frequency unit, baseband unit and control unit in the moving target detection system are directly connected to finished products, there is no integrated design and processing, there are a lot of redundant functions and interfaces, and there is a waste of functions
