Method for judging and positioning pseudo base station based on reported information of terminal

Abstract

A method for judging and positioning a pseudo base station based on reported information of a terminal includes the steps that after receiving a message, the terminal judges whether the message is a spam message or not according to key words and a mobile phone number; if yes, a message or voice service is triggered immediately; if network connection fails, the position is judged to be a suspected covering area of the pseudo base station; the longitude and latitude of the position are recorded through a GPS chip of the terminal, when network coverage recovers, the covering position of the suspected pseudo base station is uploaded to a base station; if the terminal supports a route test function, the updating time of the position area, retention and reselection parameters and area codes are stored at the same time, so that a network monitoring server accurately discriminates and draws the covering area of the suspected pseudo base station according to a great deal of information such as the longitude and latitude of the covering position of the suspected pseudo base station, wherein the information is reported by the base station and comes from the terminal or a route test terminal, and then the position where the pseudo base station is located is judged rapidly and accurately. The method is easy and convenient to operate, high in efficiency and good in accuracy and does not increase interfaces and signaling loads of the base station or a core network, and it is necessary to modify hardware configuration of the terminal and an existing communication protocol.

Description

technical field [0001] The invention relates to a method for judging and locating a pseudo base station based on information reported by a terminal, and belongs to the technical field of wireless communication systems. Background technique [0002] With the development of mobile communication technology, the cellular network standard has developed from the first generation network of analog communication to the fourth generation network of digital broadband. According to the latest report of the World Bank, the number of mobile communication users in the world has exceeded 6 billion, basically reaching a mobile phone per person. In 2013, the output value of China's communication equipment industry reached 1,509.2 billion yuan, and the output value of mobile Internet will also exceed 100 billion yuan. It is precisely because of such great business opportunities and influence that some criminals take advantage of the loopholes in the mobile communication network protocol to m...

Problems solved by technology

The content of spam messages involves bad information such as telecom fraud and illegal advertisements, so that the owners of fake base stations can obtain illegal profits

Moreover, after the terminal is connected to the pseudo base station, it cannot make calls, send and receive text messages, or initiate data services normally, and is harassed by spam text messages from time to time, which seriously affects the user experience.

Telecom operators will also cause a decline in user traffic and a serious increase in complaint rates due to the existence and harassment of pseudo base stations

[0005] The characteristics of the pseudo base station can be summarized as the following six points: (1) The transmission power of the pseudo base station is small

(2) The coverage area is small, use Yagi antenna or omnidirectional antenna, and the antenna gain is small

(3) Extreme cell residence parameters and reselection parameters, whose configuration information is easy to induce terminals to access

This method of identifying and locating fake base stations based on network monitoring does not take advantage of the positioning function of a large number of user terminals in the wireless network. It also needs to add interfaces between the base station and the core network side, and needs to detect a large amount of data for investigation and send scientific and technological personnel to search manually. As a result, its response speed is slow, and it cannot respond quickly to the moving pseudo base station

In addition, the above method does not consider the service characteristics of the terminal after accessing the pseudo base station, that is, it will receive spam text messages and cannot make calls, send text messages, or perform data services
