The Design And Implementation Of Base Station Information Querying System Based On Embedded System

In the process of current criminal case detection, the call repords have been become one of the clues to solve crimes. By collecting the base station information of the scene, the public security personnel can know which base station to provide communication service. Then they will find the suspicious number from the base station database. It can narrow the scope of suspected objects and reduce the time of screening and improve the working efficiency. But the public security personnel can not get the base station information of the scene conveniently and handle it. And they can not obtain the useful clues quickly. So in this paper, the main research work is to design and realize an information query system running on a mobile device.The system has four main functions:the main cell site information and location information acquisition and showing and storage; checking the store information; using the wireless network to transmit data to the designated IP PC server; providing electronic map service. On the server side, this paper designs and implements the software to receive and process data.The system can collect 3G/2G main cell site information, including Unicom format, Telecom format and Mobile format. It also can collect location information. After each collecting one message, the system will store it into the database and show it.Information view function can pull up the information stored in the database. Users can choose the type of information and query the specific record. It can avoid querying all the information and save time and improve the efficiency of the query.The information query system is on the client side and the designated IP PC is on the server side. The client side transmits data to the server side to help other users to use it. The server side extracts the data related to base station location to display.According to the positioning data, the system can draw those places that the data describes with the map API interface and help other users to know the geographical situation.The experimental results show that this paper implements all the functions and the system can work well.
