[0054] See also Figure 4 , provides a workflow for detecting the characteristic codes of LTE three-network users.

[0055] During the boot process, when each LTE module enters the initialization process, it shakes hands with the APP to obtain the working parameter mode. Mode 1 uses the last configuration parameters, and mode 2 uses the re-scan network self-configuration parameters. The configuration parameters of mode 1 are actually the saved results of the last network scan self-configuration parameters. The advantage is that the time for re-scanning network self-configuration is omitted, and the working state is entered faster. It is suitable for the case where the working city has not changed.

[0056] The network scanning and self-configuration process requires re-scanning and self-configuration after powering on in the case of a change of city or long-term non-use.

[0057] Establish a cell, prompt that it is ready to work, and enter the standby state to wait. In this step, each module establishes a cell according to the first working frequency in the working frequency list and sends a ready notification to the APP.

[0058] Mobile detection feature code process, after receiving the APP's command to turn on the radio frequency, the TDD-LTE module and the FDD-LTE2 module enter the mobile detection and feature code extraction workflow, and control the wireless router's Modem to work under the Modem2 route to ensure the normal access process of mobile communications. Among them, the FDD-LTE2 module works at the mobile's only FDD Band3 frequency point, and the TDD-LTE module works in multiple TDD frequencies according to the patrol rules. These working frequencies are included in Band39, Band34, Band40, and Band41. When the first round of mobile working frequencies is completed, the radio frequency is automatically turned off, the configuration is changed, and the telephone connection workflow is ready to start.

[0059] Telecom and Unicom (referred to as Telecom Union) detect feature code process. After automatically entering the process, the FDD-LTE1 and FDD-LTE2 modules enter the Telecom Union detection code and feature code extraction workflow, turn on the radio frequency, and control the wireless router's Modem to work under the Modem1 route to ensure that the Telecom Union communication access process is normal. Among them, the FDD-LTE1 module patrols under multiple frequencies of Telecom and Unicom's Band1, and the FDD-LTE2 module patrols under multiple frequencies of Telecom and Unicom's Band3. When the first round of Telecom Union working frequencies is completed, the radio frequency is automatically turned off, the configuration is changed, and preparations are made to start the mobile workflow.

[0060] After that, the device will work in a cycle of moving and connecting until the end. The end process is divided into receiving a command to turn off the radio frequency, or the device is directly turned off. After receiving the command to turn off the radio frequency, the device returns to the initial standby state.

[0061] The LTE three-carrier special detection portable device of the utility model can provide more mobile phone information besides IMSI, support the terminals of the three major domestic operators, and meet the market demand for high-level communication security. At the same time, it provides a structural design and a portable special detection device that completely isolates the signal source and the antenna.

[0063] 1. The use of three LTE signal sources can not only realize the commonly used functions such as code detection and positioning, but also realize more communication security information detection for the terminals of the three major domestic operators.
