Embodiment 1
[0047] refer to figure 1 , showing Embodiment 1 of a terminal signal shielding method of the present application, including the following steps:
[0048] Step 101, read the integrated circuit card identification code (ICCID) of the SIM card of the terminal, and check whether the information of the terminal is recorded in the database, if so, go to step 103, otherwise, go to step 102.
[0049] The terminal can be a mobile phone, a tablet computer, and other devices that can install a SIM card. The integrated circuit card identification code (ICCID, Integrate circuit card identity) in the terminal SIM card is used to uniquely identify the SIM card and the terminal with the SIM card, recorded in the unique identification number file (2FE2) of the SIM card, find the unique identification number file, the IC card identification code can be read from it.
[0050] Reading the IC card identification code of the terminal SIM card can be realized by a card reader capable of reading SI...

The invention provides a method for shielding a terminal signal. The method comprises the following steps of: reading an integrated circuit card identification code of a terminal subscriber identity module (SIM), querying whether terminal information is recorded in a database; if the terminal information is recorded in the database, executing the next step; if the terminal information is not recorded in the database, reading an international mobile user identification code of the terminal SIM, recording the integrated circuit card identification code and the international mobile user identification code as the terminal information, and executing the next step; transmitting a file content update instruction to the SIM, and emptying the international mobile user identification code in an international mobile user identification number file of the SIM; and transmitting a restarting instruction to the SIM, and restarting a terminal. The invention also provides a device for shielding the terminal signal, a method and a device for removing shielding of the terminal signal, and a terminal signal management system. By the devices, the methods and the system, a signal shielding range can be expanded, and utilization cost can be reduced.
Description
technical field [0001] The present application relates to the technical field of mobile signal processing, in particular to a terminal signal shielding device and method, a canceling device and method, and a management system. Background technique [0002] With the rapid development of mobile communication technology, terminals such as mobile phones are popular among users due to their convenience, speed, and freedom from time and place restrictions. One of the missing tools. While mobile phones are becoming more and more popular and bringing great convenience to people, it should also be seen that with the unlimited use of mobile phones, the noise pollution produced by mobile phones has become more and more serious. For example, in conference rooms, courtrooms, theaters, libraries, hospitals, academic lecture halls, classrooms and other public places, the random use of mobile phones affects and interferes with the normal progress of certain activities. In special places i...
