Under the sweep frequency mode, the sweep frequency thread and the double DSPs work in a coordinated manner, and LTE sweep frequency, WCDMA sweep frequency and GSM sweep frequency are started in sequence. For example, in China, LTE scans Band1, band3, band5, band8, band34, band39, band40 and Band41 in sequence, WCDMA scans Band1 and Band8 in sequence, and GSM scans Band3 and Band8 in sequence. After the cell signal is scanned, the MIB and the main SIB are analyzed to obtain key information such as cell signal strength (RSRP), an operator code (PLMN), a frequency point (ARFCN), a Physical Cell ID (PCI) or a Primary Scrambling Code (PSC), and the same-frequency and different-frequency cell information of each cell.
The self-configuration algorithm extracts the key information, screens and sorts the key information according to a certain algorithm to obtain a working parameter combination list, and the most main parameters are working frequency points and working modes.
Next, the device enters an operation mode, and starts from LTE generally in China when starting the first set of operation modes and frequency points. If the suspected mobile phone currently resides on a certain frequency point of the LTE, when the equipment also operates to the frequency point, the suspected mobile phone can be quickly switched from an operator cell to the same frequency point cell of the equipment, and in the signaling interaction process, an International Mobile Subscriber Identity (IMSI) of the suspected mobile phone can be obtained, and the number is globally unique and is stored in a mobile phone SIM card. If the suspected mobile phone is not found in the first group of working frequency points, the mobile phone is switched to the second group of working modes and frequency points after a certain time (generally from tens of seconds to minutes).
If a suspected mobile phone is found in a certain working frequency point, the carrier wave can be kept unchanged, meanwhile, a measurement report of the mobile phone is initiated, and the position searching function of the mobile phone is completed independently or in combination with other tools.
The working mode of the dual carrier can be any one of the following combinations:
LTE-FDD1 and LTE-FDD2
LTE-TDD1 and LTE-TDD2
WCDMA1 and WCDMA2
GSM1 and GSM2
LTE-FDD1 and LTE-TDD1
LTE-FDD1 and WCDMA1
LTE-FDD1 and GSM1
LTE-TDD1 and WCDMA1
LTE-TDD1 and GSM1
WCDMA1 and GSM1
The working frequency point of the dual carrier can be any frequency point in a frequency Band of Band1\3\5\8\34\39\40\41.
Compared with the prior art, the 2G, 3G and 4G integrated dual-carrier portable detection device has the following beneficial effects:
1. The baseband board adopted by the invention supports dual carriers, each carrier can support any system of 2G (GSM)/3G (WCDMA)/4G (LTE-TDD and LTE-FDD), the two carriers can be any combination of the systems, and the invention also supports real-time switching work among the systems, thereby being very practical and convenient in the detection industry.
2. The invention adopts the broadband power amplifier and the built-in duplexer/filter technology to support all 8 working frequency bands of 234G in China, combines 8 power amplifiers and a plurality of external multichannel duplexer/filters into 3 power amplifier units, greatly reduces the volume, weight, power consumption and complexity of the equipment and realizes the portability of the equipment.
3. The invention adopts original radio frequency exchange technology to realize the random communication between the baseband signal of the double carrier and a plurality of frequency bands of a plurality of power amplifiers, thereby satisfactorily solving the limitation of signal amplification in the traditional equipment and leading the equipment to have extremely high practicability.
4. The device supports an independent frequency sweep function, realizes the function of scanning 2G/3G/4G environment signals on each frequency band and decoding the environment signals, and can be used as an input source for self-configuration work of the device and also can be used as an independent frequency sweep decoder.
The foregoing description of the preferred embodiments of the invention is not intended to limit the scope of the invention, but is intended to cover any modifications, equivalents, and improvements within the spirit of the invention.
