All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to overcome the problems in the prior art, the embodiment of the invention provides an electronic fence system and an operation method thereof, and the invention has the advantages that the signal changes of an electronic fence and a public network base station are monitored in real time, the coverage area of the electronic fence is adjusted in time, and the interference to a public network is reduced. The coverage of the target area is automatically obtained and conveniently adjusted, and the interference to the public network environment is reduced and eliminated.
Fig. 1 is a schematic structural diagram of an electronic fence system according to an embodiment of the present invention. As shown in fig. 1, the electronic fence system includes a communication base station 101, a monitoring apparatus 102, and a control apparatus 103.
And the communication base station 101 is used for transmitting the cell signals with the transmission power to form an electronic fence.
Specifically, the communication base station 101 may be a base station supporting any one of communication systems such as 2G, 3G, 4G, and 5G. Preferably, the communication base station 101 may be a 4G base station.
The communication base station 101 may include a GPS module, a tri-baseband board, filters of each frequency band, and a power amplifier, and is implemented to establish a TDD cell and two FDD cells so that a user terminal (e.g., a mobile phone) can successfully camp on the TDD cell and the FDD cell.
The communication base station 101 may also include one transmit antenna. The transmitting antenna can be an omnidirectional antenna, and transmits the cell signal of the base station by using transmitting power, so that corresponding gain amplification is realized, and a certain range is covered.
The communication base station 101 is generally disposed near the center of the target area.
And the monitoring device 102 is configured to receive a cell signal and a public network signal.
In particular, the monitoring device 102 may include an antenna. The antenna may be disposed near an edge of the target area for receiving cell signals and public network signals transmitted by the communication base station 101.
The public network is a mobile communication network of a mobile communication operator. The public network signal is a signal transmitted by a base station of a mobile communication operator.
The monitoring device 102 may be electrically connected to the control device 103, and may transmit the received cell signal and the public network signal to the control device 103.
And the control device 103 is configured to determine a new transmission power according to the signal strengths of the cell signal and the public network signal if it is determined that the signal strengths and the frequency point information of the cell signal and the public network signal meet the preset power adjustment condition, so that the communication base station transmits the cell signal with the new transmission power.
Specifically, after the control device 103 acquires the cell signal and the public network signal sent by the monitoring device 102, the signal strength and the frequency point information of the cell signal and the signal strength and the frequency point information of the public network signal may be acquired according to the cell signal and the public network signal.

If not, it indicates that the electronic fence formed by the communication base station 101 with the current transmission power can meet the access of the communication terminal within the coverage area of the electronic fence, and will not cause interference to the public network. Therefore, the transmission power of the communication base station 101 does not need to be adjusted.
If the current transmission power is satisfied, it indicates that the electronic fence formed by the communication base station 101 with the current transmission power may cause that the communication terminal cannot normally access in the coverage area of the electronic fence, or cause interference to the public network. Therefore, the transmission power of the communication base station 101 needs to be adjusted.

Accordingly, the control device 103 may first determine whether the signal strength and the frequency point information of the cell signal acquired this time and the signal strength and the frequency point information of the public network signal have changed compared with the previous time.
If no change occurs, the explanation is the same as the previous case, and it is not necessary to determine whether the preset power adjustment condition is satisfied. If the situation is the same, judging whether the preset power adjustment condition is met.

Qrxlevmeas>＝threshX-High+Qrxlevmin。

Therefore, the minimum value of the signal strength of the cell signal under the pilot frequency adsorption condition can be calculated.
In order to control the coverage area and reduce the interference to the public network, the signal strength of the cell signal with the limitation condition is increased to be not more than threshX-High + Qrxlevmin + N2.
