Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] The basic idea of ​​the present invention is: the radio frequency front-end, modem, codec, protocol stack and upper layer application module (scan configuration module, position update processing module, authentication and encryption module, storage module) constitute the special device capable of obtaining the IMEI of the mobile communication terminal. Base station, the base station can simulate the current wireless network functions but cannot provide communication services, and can simulate the completion of the location update process. The base stations mentioned below refer to this special base station. When the mobile communication terminal detects a strong signal in the coverage area of ​​the base station and there is no communication service, the mobile communication terminal actively initiates a location update request, and the base station simulates the c...

Abstract

The invention discloses a device and method for obtaining an international mobile equipment identifier of a mobile communication terminal by a base station. The device comprises a radio frequency front end, a modulator-demodulator, a coder-decoder, a protocol stack, a scanning configuration module, a position updating and processing module, an authentication and encryption module and a storage module, wherein the radio frequency front end is used for transmitting and receiving a radio frequency signal of a global system for mobile communications, receiving a signal from the modulator-demodulator to be transmitted in a free space, and receiving a signal from the free signal to be processed by the modulator-demodulator; and the modulator-demodulator is used for modulating and demodulating the radio frequency signal of the global system for mobile communications, demodulating the signal coded by the coder to be transmitted by the radio frequency front end, and demodulating the signal of the global system for mobile communications, which is received by the radio frequency front end and is decoded by the decoder. By adopting the device and the method, an identifier of a mobile communication terminal in a coverage range of the base station can be immediately obtained.

Description

technical field [0001] The invention relates to a method and a device for acquiring information of a mobile communication terminal, in particular to a method and a device for acquiring an international mobile equipment identification code of a mobile communication terminal, and the invention belongs to the technical field of mobile communication. Background technique [0002] International Mobile Equipment Identity (IMEI) is an "electronic serial number" consisting of 15 digits. This code is unique in the world, it corresponds to each mobile communication terminal one by one, and can be used to identify each independent mobile communication terminal in the mobile communication network, which is equivalent to the ID card of the mobile communication terminal. After each mobile communication terminal is assembled, it will be given a globally unique serial number, which will be recorded by the mobile communication equipment manufacturer from the production of the terminal to del...
