Description

Technical Field

[0001] The embodiments of the present invention relate to the field of wireless communications, and in particular, to a method, device, storage medium and electronic device for sending an interference signal. Background Art

[0002] Mobile communication public network shielding technology is widely used in places such as examination halls where mobile phone communications need to be prohibited. Signal interference equipment is used to absorb or prevent mobile phones from connecting to the mobile communication public network. For example, based on receiving the (wireless) frame signal of the air base station, the LTE and 5G base station signals are shielded by signal forwarding. This method has the advantages of high shielding efficiency, controllable boundaries, and no interference to the base station. The current signal interference equipment receives the base station signal sent by the base station in real time, and uses the base station signal received in the current time slot as the shielding signal of the current time slot, thereby interfering with the base station signal of the current time slot received by the mobile phone. However, since the traffic volume carried by the base station signal sent by the base station during normal operation of the base station is fluctuating, the power of the base station signal sent by the base station is fluctuating in real time. At this time, the output power of the signal interference device shielding signal also fluctuates synchronously. The signal interference device consumes a lot of power when working in this variable power state for a long time, and the shielding effect of the signal is also poor.

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a block diagram of the hardware structure of a mobile terminal of the method for sending an interference signal according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0028] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for sending interference signals in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0029] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0030] In this embodiment, a method for sending an interference signal is provided. Figure 2 is a flow chart of a method for sending an interference signal according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0031] Step S202, obtaining a first base station signal sent by the base station in the current downlink timeslot;

[0032] Step S204, acquiring a second base station signal whose traffic volume carried by the base station signal meets the traffic volume condition from the first base station signal and the base station signal set, wherein the base station signal set is used to record the base station signal sent by the base station received before the current downlink timeslot;

[0033] Step S206: generating an interference signal according to the second base station signal, wherein the interference signal is used to interfere with decoding of the first base station signal;

[0034] Step S208: sending the interference signal to a terminal that receives the first base station signal.

[0035] Through the above steps, the base station signal sent by the base station before the current downlink time slot is recorded in the base station signal set. When generating an interference signal, the second base station signal whose business volume carried in the base station signal meets the business volume condition is first obtained from the first base station signal and the base station signal set, so that the business volume of the second base station signal used when generating the interference signal is relatively stable. Therefore, the operating power of the signal interference device is relatively stable when generating the interference signal. This also facilitates increasing the interference area of ​​the signal interference device, and can also ensure the quality of the generated interference signal, thereby improving the interference quality of the base station signal. Therefore, the problem of low interference signal generation efficiency of the signal interference device in the related technology is solved, and the effect of improving the interference signal generation efficiency of the signal interference device is achieved.

[0036] In the technical solution provided in the above step S202, the first base station signal can be a base station signal sent by one or more base stations in the current downlink time slot. In the case where the first base station signal is multiple base station signals sent by multiple base stations, the signal parameters of each base station signal can take any value, for example, the base station signal can be any frequency point, any frequency band, etc., and this solution does not limit this.

[0037] Optionally, in this embodiment, the base station can be a base station of any business mode, for example, the base station can be but not limited to a 4G base station, a 5G base station, a frequency division duplex base station, a time division duplex base station, etc., and this solution does not limit this.

[0038] In the technical solution provided in the above step S204, what is stored in the base station signal set may be all base station signals sent by the base station received within the target time period before the current time slot, or part of the base station signals sent by the base station received within the target time period before the current time slot. For example, all base station signals sent by the base station received within 5 minutes before the current time slot may be stored in the base station signal set, or base station signals sent by the base station that meet the traffic volume conditions and are received within 5 minutes before the current time slot may be stored in the base station signal set, and the base station signal set may be updated in real time by replacing the base station signal of the earliest time slot with the base station signal of the latest time slot, or base station signals sent by the base station that meet the traffic volume conditions and are received within 5 minutes before the current time slot may be stored in the base station signal set.

[0039] Optionally, in this embodiment, the traffic volume condition may be, but is not limited to, indicating a base station signal whose traffic volume carried by the base station signal falls within a target traffic volume range. The target traffic volume range may be pre-set, or may be generated based on the traffic volume carried by the first base station signal and the base station signals in the base station signal set, or, for example, based on the traffic volume carried by the first base station signal and the traffic volume carried by the base station signals in the base station signal set, the traffic volume carried by the base station signal with the largest or smallest traffic volume is used as the boundary value of the target traffic volume range.

[0040] In the technical solution provided in the above step S206, generating an interference signal based on the second base station signal may include but is not limited to screening the second base station signal and using the screened base station signal as the interference signal, or may also include extracting features from the second base station signal and generating an interference signal based on the extracted features, which is not limited in this solution.

[0041] In the technical solution provided in the above step S208, the interference signal may be sent in an omnidirectional broadcast manner, or may be sent in a directionally directed manner to a designated terminal.

[0042] As an optional embodiment, acquiring, from the first base station signal and the base station signal set, a second base station signal whose traffic volume carried by the base station signal meets a traffic volume threshold, includes:

[0043] Acquire the time domain power of the first base station signal and the time domain power of each base station signal included in the base station signal set to obtain a time domain power set;

[0044] A second base station signal whose corresponding time domain power falls within a target time domain power range is obtained from the first base station signal and the base station signal set according to the time domain power set, wherein the traffic carried by the second base station signal is less than a target traffic volume threshold.

[0045] Optionally, in this embodiment, the time domain power of the base station signal is used to indicate the traffic volume carried by the base station signal. For example, when the traffic volume carried by the base station signal is low, the difference between the power of the symbol area containing the reference symbols and the power of the symbol area not containing the reference symbols in the time domain power of the base station signal is large. Therefore, the larger the difference between the power of the symbol area containing the reference symbols and the power of the symbol area not containing the reference symbols, the smaller the traffic volume carried by the base station signal.

[0046] Optionally, in this embodiment, the target power range is used to indicate a value range of the power of a symbol area containing reference symbols and the power of a symbol area not containing reference symbols in the time domain power of the base station signal.

[0047] As an optional embodiment, acquiring, according to the time domain power set, from the first base station signal and the base station signal set, a second base station signal whose corresponding time domain power falls within a target time domain power range, includes:

[0048] Acquire a first time domain power in which a first time domain power level value and a second time domain power level value in the time domain power set fall within the target time domain power range, wherein the first time domain power level value is determined according to a time domain power level value of a symbol area including a reference symbol in a base station signal, and the second time domain power level value is determined according to a time domain power level value of a symbol area not including the reference symbol in the base station signal, and the reference symbol is a symbol used to demodulate base station transmission information;

[0049] The base station signal corresponding to the time domain power with the largest difference between the first time domain power level value and the second time domain power level value in the first time domain power is determined as the second base station signal, wherein the difference between the first time domain power level value and the second time domain power level value is negatively correlated with the traffic carried by the base station signal.

[0050] Optionally, in this embodiment, the reference symbols may include but are not limited to CRS (Common Reference Signal), PSS (Primary Synchronization Signal), SSS (Secondary Synchronization Signal), PBCH (Physical Broadcast Channel), etc., and this solution does not limit this.

[0051] Optionally, in this embodiment, the time domain power of the base station signal includes a symbol area of ​​reference symbols and a symbol area not including reference symbols. The symbol area not including reference symbols is used to transmit pure business data. Therefore, the time domain power level value of the symbol area not including reference symbols in the time domain power of the base station signal will change with the change of business volume (the minimum is no signal transmission), while the power level value of the reference symbol is relatively stable. Therefore, the lower the business volume carried by the base station signal, the greater the difference between the time domain power level value of the symbol area including reference symbols and the time domain power level value of the symbol area not including reference symbols. Figure 3 is an optional base station signal configuration diagram according to an embodiment of the present invention, which can be applied to, but not limited to, frequency division duplex base station signals and time division duplex base station signals, such as Figure 3 As shown, a downlink time slot includes 7 symbol areas, which are symbol areas for reference symbols and pure data symbol areas (symbol areas not including reference symbols). It should be noted that the positions and numbers of reference symbols in this embodiment are only examples. In practical applications, any number of reference symbols (including but not limited to CRS, PSS, SSS, PBCH, etc.) can be set in the first symbol area and the fifth symbol area but are not limited to it. When the data service changes, since the other symbol areas among the 7 symbol areas except the first symbol area and the fifth symbol area do not include reference symbols, the power level values ​​of these symbol areas not including reference symbols change significantly.

[0052] According to the above embodiment, when calculating the service idleness, each base station signal can be scored in the following manner to determine the service volume of the base station signal. The carrier time domain power is used to measure to obtain the symbol power level of each symbol area containing a reference symbol. The maximum power level among them is selected in the frame as the benchmark for the power level of the symbol area including the reference symbol. The carrier time domain power is used to measure and compare the maximum levels of the power levels of other pure data symbols without reference symbols. Then, the level difference of the maximum power level of the symbol area without reference symbols is selected as the level value of the pure data symbol. The maximum power level of the symbol area containing the reference symbol is subtracted from the maximum power level of the symbol area not containing the reference symbol. The level difference represents the idleness. It is recommended to calculate the level difference in dB and give 1 point for each dB to obtain the service idleness score of the base station signal, and then determine the service volume of the base station signal based on the score.

[0053] Optionally, in this embodiment, the first time domain power level value may be, but is not limited to, the maximum value or effective value of the time domain power level value of the symbol area including the reference symbol. Similarly, the second time domain power level value may be, but is not limited to, the maximum value or effective value of the time domain power level value of the non-symbol area not including the reference symbol. Figure 4 is an optional time domain power of a base station signal when the traffic is idle according to an embodiment of the present invention. Figure 1 ,like Figure 4 As shown, the first marking line is the marking line of the maximum value of the first time domain power level value of the symbol area including the reference symbol, and the second marking line is the marking line of the maximum value of the second time domain power level value of the symbol area of ​​the pure business symbol not including the reference symbol. Since there may be a symbol area including the reference symbol and a symbol area of ​​the pure business symbol not including the reference symbol in the time domain rate, and when the business volume of the base station signal is relatively idle, the business symbol is small or may be a non-business symbol, so the time domain power level of the symbol area of ​​the pure business symbol is also low. Since the reference symbol is unchanged and is always sent, the difference between the maximum value of the first time domain power level value of the symbol area including the reference symbol and the maximum value of the second time domain power level value is large, and the larger the difference between the maximum values ​​of the first time domain power level value and the second time domain power level value is, the lower the business volume carried by the base station signal is. Therefore, it can be determined that the base station signal is a base station signal with idle business volume.

[0054] Similarly, whether the traffic volume of the base station signal is idle can also be determined based on the difference between the effective value of the time domain power level value of the symbol area including the reference symbol and the effective value of the time domain power level value of the symbol area not including the reference symbol. The larger the difference between the two effective values, the more idle the traffic volume is. Figure 5 is an optional time domain power of a base station signal when the traffic is idle according to an embodiment of the present invention. Figure 2 ,like Figure 5 As shown, the first marking line is a marking line of the effective value of the first time domain power level value of the symbol area including the reference symbol, and the second marking line is a marking line of the effective value of the second time domain power level value of the symbol area of ​​the pure business symbol not including the reference symbol. Since there may be a symbol area including the reference symbol and a symbol area of ​​the pure business symbol not including the reference symbol in the time domain power, and when the business volume of the base station signal is relatively idle, the business symbol is small or may be a non-business symbol, so the time domain power level of the symbol area of ​​the pure business symbol is also low. Since the reference symbol is unchanged and is always sent, the difference between the effective value of the first time domain power level value of the symbol area including the reference symbol and the effective value of the second time domain power level value is large, and the larger the difference between the effective values ​​of the first time domain power level value and the second time domain power level value is, the lower the business volume carried by the base station signal is. Therefore, it can be determined that the base station signal is a base station signal with idle business volume.

[0055] As an optional embodiment, acquiring, according to the time domain power set, from the first base station signal and the base station signal set, a second base station signal whose corresponding time domain power falls within a target time domain power range, includes:

[0056] Acquire a second time domain power whose time domain power level value in the time domain power set falls within the target time domain power range;

[0057] Obtain a target time domain power graph of each of the second time domain powers;

[0058] The base station signal corresponding to the time domain power graph with the greatest similarity to the preset time domain power graph in the target time domain power graph is determined as the second base station signal, wherein the preset time domain power graph is a time domain power graph of a preset base station signal whose traffic volume is less than the target traffic volume threshold.

[0059] Optionally, in this embodiment, the time domain power of the base station signal includes a symbol area of ​​reference symbols and a symbol area not including reference symbols, and the symbol area not including reference symbols is used to transmit pure business data, so the time domain power level value of the symbol area not including reference symbols in the time domain power of the base station signal will change with the change of business volume, while the power level value of the reference symbol is relatively stable, so when the business volume is relatively full, the level peak value of each symbol area in the time domain power diagram of the base station signal is relatively stable, and when the base station signal carries relatively idle business, the power level peak value of the symbol area including reference symbols and the symbol area not including reference symbols is relatively different, so the power level peak value (or effective value) of the symbol area including reference symbols and the power level peak value (or effective value) of the symbol area not including reference symbols in the time domain power diagram of the base station signal with idle business are relatively different. Then, the business volume of the base station signal can be determined according to the similarity between the target time domain power diagram and the preset time domain power diagram of the base station signal with idle business.

[0060] Figure 6 is an optional time domain power diagram of a base station signal with relatively full traffic according to an embodiment of the present invention, such as Figure 6 As shown in FIG. 1 , when the traffic volume of the base station signal is relatively high, the time domain power level value of the symbol area including the reference symbol in the downlink time slot of the base station signal is relatively similar to the time domain power level value of the pure traffic symbol area not including the reference symbol, that is, when the traffic volume is relatively high, the time domain power level value in the base station signal is relatively smooth and stable. Therefore, the time domain power diagram of the base station signal can reflect the traffic volume of the base station signal, and when the shapes of the time domain power diagrams are similar, the traffic volume carried by the base station signal is also similar, so the traffic volume of the base station signal can be determined by comparing the similarity of the shapes between the target time domain power diagram and the preset time domain power diagram.

[0061] Figure 7 is another optional time domain power diagram of a base station signal with idle traffic according to an embodiment of the present invention, such as Figure 7 As shown in the figure, when the traffic volume of the base station signal is relatively idle, the time domain power level value of the symbol area including the reference symbol in the downlink time slot of the base station signal is greatly different from the time domain power level value of the pure service symbol area not including the reference symbol, that is, the time domain power level value of the symbol area of ​​the reference symbol in the figure is in the interval of (-40, -50), while the time domain power level value of the pure service symbol area not including the reference symbol is mostly in the interval of (-80, -90). Therefore, the time domain power diagram of the base station signal can reflect the traffic volume of the base station signal, and then when the shapes of the time domain power diagrams are similar, the traffic volume carried by the base station signal is also similar, so the traffic volume of the base station signal can be determined by comparing the similarity of the shapes between the target time domain power diagram and the preset time domain power diagram.

[0062] From the above content, it can be seen that the shape of the time domain power graph of the base station signal can determine the traffic volume carried by the base station signal. By comparing the similarity between the time domain power graph of the base station signal and the preset time domain power graph of the base station signal with idle traffic, the traffic volume carried by the base station signal can be determined based on the similarity, thereby improving the efficiency of determining the traffic volume carried by the base station signal.

[0063] As an optional embodiment, the generating an interference signal according to the second base station signal includes:

[0064] When there are multiple base stations, and the second base station signal includes multiple base station signals corresponding to the multiple base stations one by one, determining the third base station signal according to the multiple base station signals;

[0065] The interference signal corresponding to the third base station signal is generated.

[0066] Optionally, in this embodiment, the method of determining the third base station signal based on multiple base station signals may be to directly determine the multiple base station signals as the third base station signal, or to merge the multiple base station signals into a third base station signal, or to select a base station signal from multiple base station signals as the third base station signal. For example, corresponding weight values ​​are set according to the signal strength of each base station signal. The stronger the base station signal, the larger the weight value, and a weighted calculation is performed on the service idleness of the base station signal, and the base station signal with the largest calculated result is used as the third base station signal; or corresponding weight values ​​are set according to the carrier power of each base station signal. The larger the carrier power, the larger the weight value, and a weighted calculation is performed on the service idleness of the base station signal, and the base station signal with the largest calculated result is used as the third base station signal.

[0067] As an optional embodiment, determining a third base station signal according to the multiple base station signals includes:

[0068] Determine the multiple base station signals as the third base station signal;

[0069] Combining the multiple base station signals into the third base station signal;

[0070] In the case where the multiple base stations are heterofrequency base stations, a third base station signal is screened out from the multiple base station signals according to the traffic carried by each base station signal in the multiple base station signals and the carrier power of each base station signal in the multiple base station signals.

[0071] Optionally, in this embodiment, determining multiple base station signals as a third base station signal can be applied to same-frequency base station signals, or can also be applied to different-frequency base station signals. For example, when multiple base station signals are same-frequency base station signals, multiple base station signals can be directly used as the third base station signal, thereby making the signal shielding more efficient. Or, when multiple base station signals are different-frequency base station signals, multiple different-frequency base station signals can be directly used as the third base station signal (different frequency points are independent of each other, and each interferes with the signal within its own frequency point) to shield signals at different frequency points.

[0072] Optionally, in this embodiment, merging multiple base station signals into a third base station signal can be applied to same-frequency base station signals, or can also be applied to different-frequency base station signals. For example, when multiple base station signals are same-frequency base station signals, multiple same-frequency base station signals are merged and the merged base station signal is used as the third base station signal. Alternatively, when multiple base station signals are different-frequency base station signals, multiple different-frequency base station signals form a frequency band, and multiple different-frequency base station signals are merged into a multi-frequency base station signal to obtain a third base station signal corresponding to the frequency band, and the signal of the frequency band is shielded by the base station signal.

[0073] Optionally, in this embodiment, when multiple base stations are heterofrequency base stations, a target weight can be assigned to each of the multiple base station signals according to the reference signal strength of each base station signal in the multiple base station signals, wherein there is a positive correlation between the target weight corresponding to each of the multiple base station signals and the signal strength of each of the multiple base station signals, and the product of the service volume idleness of each of the multiple base station signals (the ratio of the difference between the rated service volume of the base station signal and the service volume carried by the base station signal to the rated service volume) and the target weight corresponding to each of the multiple base station signals is calculated, and the base station signal with the largest product among the multiple base station signals is determined as the third base station signal; or the base station signal carrying the smallest service volume among the multiple base station signals can be directly determined as the third base station signal.

[0074] Optionally, in this embodiment, when multiple base station signals are hetero-frequency base station signals, the hetero-frequency base station signals can be processed by using a filter (generally a digital filter) to separate the transmission of different frequency points, synthesizing the frequency bands of multiple frequency points first, and amplifying and transmitting them with a wide-band power amplifier, or amplifying and transmitting them independently at each frequency point. Of course, the minimum service mixed frame with the minimum service volume can also be directly transmitted using the received frequency band signal, and the mixed frame includes the base station signal with the minimum service volume carried by each base station in the multiple base stations at multiple frequency points.

[0075] Optionally, in this embodiment, when there are same-frequency base stations and different-frequency base stations in multiple base stations, the base station signals of the same-frequency base stations can be first screened to obtain a fourth base station signal, and then the fourth base station signal and the base station signals corresponding to the different-frequency base stations can be screened, thereby achieving screening out the third base station signal from the multiple base station signals corresponding to the multiple base stations.

[0076] As an optional embodiment, the filtering out a third base station signal from the multiple base station signals according to the traffic volume carried by each base station signal in the multiple base station signals and the carrier power of each base station signal in the multiple base station signals includes:

[0077] Allocating a target weight to each of the multiple base station signals according to the carrier power of each of the multiple base station signals, wherein there is a positive correlation between the target weight corresponding to each of the multiple base station signals and the carrier power of each of the multiple base station signals;

[0078] Calculate the product of the service idleness carried by each base station signal in the multiple base station signals and the target weight corresponding to each base station signal in the multiple base station signals, wherein the service idleness is used to indicate the size of the difference between the rated service carrying capacity and the actual service carrying capacity of the base station signal;

[0079] The base station signal corresponding to the largest product among the multiple base station signals is determined as the third base station signal.

[0080] Optionally, in this embodiment, the target weight is determined according to a ratio of a carrier power of each base station signal to a carrier power of base station signals of multiple base station signals.

[0081] Optionally, in this embodiment, when the carriers of each base station in a certain frequency band (or part or local frequency band) are operated synchronously (such as TDD system), this frequency band can also be treated as a (ultra-wideband) base station, and the idleness of multiple base stations after mixing is determined according to the symbol power level, so that the base station signal with the largest idleness is used as the third base station signal.

[0082] Optionally, in this embodiment, the service idleness can be determined, but is not limited to, based on the similarity between the time domain power graph of each base station signal and a preset time domain power graph (the preset time domain power graph is the time domain power graph of a preset base station signal with a traffic volume less than a target traffic volume threshold), or based on the degree of proximity between the difference between the first time domain power level value and the second time domain power level value of the base station signal and a preset difference value (the preset difference is the difference between the first time domain power level value and the second time domain power level value in the preset base station signal with a traffic volume less than the target traffic volume threshold) (the first time domain power level value is determined based on the time domain power level value of the symbol area including the reference symbol in the base station signal, and the second time domain power level value is determined based on the time domain power level value of the symbol area not including the reference symbol in the base station signal).

[0083] Figure 8 is a schematic diagram of an optional interference signal transmission according to an embodiment of the present invention, such as Figure 8 As shown, the steps may include but are not limited to:

[0084] S801, receiving a first base station signal sent by a base station in a current downlink timeslot;

[0085] S802, since there may be multiple base stations within the area, these base stations may be base stations of the same frequency or base stations of different frequencies, the base station signal of each base station is stored, and the base station signals of the same base station in different time slots are stored in the same storage location (the base station signal received in the current downlink time slot is stored in the base station signal set corresponding to the base station);

[0086] S803, for the base station signal of each base station, calculate the service idle score of the base station signal stored in each base station signal set in chronological order (the score is used to indicate the amount of service carried by the base station signal. The larger the score, the smaller the amount of service carried and the more idle the base station signal). When calculating the service idle score of the base station signal, first calculate the power level of each base station signal symbol area (which may be but is not limited to using RMS (Root Mean Squared Signal)). Square, root mean square (RMS) calculation), using carrier time domain power to measure to obtain the maximum value or effective value (first time domain power level value) of the time domain power level value of each symbol area containing reference symbols (which may include but is not limited to CRS, PSS, SSS, PBCH, etc.), using carrier time domain power to measure and compare the maximum value or effective value (second power level value) of the power level value of the symbol area of ​​pure data symbols without reference symbols, using the difference between the first time domain power level value and the second time domain power level value, the difference obtained represents the score of the service idleness degree (for example, calculated according to the power level difference dB value, 1 point per dB); or the time domain power map of the base station carrier power can also be matched with the preset time domain power map (the time domain power map of the base station signal whose base station business volume is lower than the target business volume), and the preset time domain power map must be corrected through multiple trainings and scored according to the degree of matching (similar to the above calculation rules).

[0087] S804, based on the service idleness score of each base station signal calculated in the previous step within a period of time, select the second base station signal (with the smallest traffic volume) with the largest service idleness score of each base station. At this time, the number of base stations and the base station frequency in the area need to be considered, and the third base station signal with good interference effect on multiple base station signals is selected as the interference signal from the second base station signal corresponding to each base station in the multiple base stations. For each frequency band containing multiple base station frequency points and not running synchronously, it is recommended that each base station judge and score separately, select the second base station signal of each base station, and then combine the weight value corresponding to the carrier power of the base station signal (the larger the carrier power, the higher the weight). The second base station signals of multiple base stations can also be synthesized into frequency band radio frequency signals for shielding; specifically, for base stations with the same frequency, which are generally synchronized with each other, the third base station signal can be directly determined according to the multiple second base station signals (for example, the multiple base station signals are determined as the third base station signal, or the mixed base station signal is used as the third base station signal). For the case where multiple base stations are different frequency base stations, the weight value corresponding to the carrier power of the base station signal is combined (the larger the carrier power, the larger the weight value), and each second base station signal is comprehensively scored, and the base station signal with the highest comprehensive score is determined as the third base station signal;

[0088] S805, performing a digital-to-analog conversion operation on the determined third signal, thereby obtaining an interference signal;

[0089] S806, sending an interference signal to a terminal device that receives a base station signal, and updating the base station signals stored in the base station signal set, and removing the base station signal with the earliest receiving time in the base station signal set.

[0090] In the above embodiment, the base station signal carrying the largest business volume can also be selected from the first base station signal received by each base station in the current time slot and the base station signal received before the current time slot to be determined as the second base station signal, that is, the full-service base station signal (equivalent to occupying all resources (all symbols have power), shielding without gaps, complete and stable shielding, and requiring large power); and the base station signal interference method in the above embodiment is also applicable to base station signals of various communication standards, such as 4G, 5G, etc.

[0091] In the above embodiment, the base station carrier (synchronous carrier can be combined for processing) is used for continuous (OFDM symbol) power sampling, and the power template of the time domain power of the base station sending only the reference signal is used as the optimal benchmark to match the received current base station (wireless) frame, and the best frame is stored as a shield (the suboptimal frame can be saved as a time accumulation update) (note that the time scale (i.e. the time length from the extraction time of the frame to the present moment) is used as the time-based decision condition). This improves the interference efficiency of the signal interference device on the base station signal.

[0092] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

[0094] Through the above steps, the base station signal sent by the base station before the current downlink time slot is recorded in the base station signal set. When generating an interference signal, the second base station signal whose business volume carried in the base station signal meets the business volume condition is first obtained from the first base station signal and the base station signal set, so that the business volume of the second base station signal used when generating the interference signal is relatively stable. Therefore, the operating power of the signal interference device is relatively stable when generating the interference signal. This also facilitates increasing the interference area of ​​the signal interference device, and can also ensure the quality of the generated interference signal, thereby improving the interference quality of the base station signal.
