Description

Technical Field

[0001] This application relates to the field of general data processing technology, and in particular to a method and apparatus for switching frequency bands for code detection. Background Technology

[0002] Detection devices are based on the principle of wireless communication base station technology. By simulating the broadcast inducement signals of a mobile communication network operator, they provide a stronger signal than public network base stations, thereby attracting terminal devices. Currently, public network base stations transmit signals in different frequency bands. When a terminal device attempts to access a signal, it will prioritize accessing the signal with the highest frequency band that it can access. Higher frequency signals have a smaller propagation range and weaker penetration ability than lower frequency signals.

[0003] Therefore, when the terminal device is located in a high-rise building or in other obstructed conditions, it cannot access high-frequency signals and can only access low-frequency signals. When the detection device attaches to the terminal device, it also needs to select the corresponding signal frequency band. Failure to select the appropriate frequency band will waste a significant amount of time and hinder the detection operation. Summary of the Invention

[0004] This application provides a method and apparatus for switching frequency bands for code detection. By utilizing the public network frequency signals within the current signal coverage area of ​​the code detection device, as well as the network frequency signals between the target terminal device and the public network base station, the communication signal frequency band with the target terminal device is determined. This avoids the significant time wasted due to incorrect signal frequency band selection when targeting the target terminal device, thereby improving the efficiency of the code detection device in completing the targeting of the target terminal device.

[0005] In a first aspect, embodiments of this application provide a code detection frequency band switching method, which is applied to a code detection device, and the method includes:

[0006] Obtain the first public network frequency point information within the current signal coverage area, and determine whether the first public network frequency point information includes the first type of signal frequency point;

[0007] If the first type of signal frequency is included in the first public network frequency information, obtain the network frequency information of the communication connection between the target terminal device and the public network base station, where the target terminal device is a terminal device within the target area of ​​the detection device;

[0008] If the network frequency information includes the first type of signal frequency, then the signal frequency band corresponding to the first type of signal frequency will be used to perform the attraction operation on the target terminal device;

[0009] If the network frequency information does not include the first type of signal frequency but includes the second type of signal frequency, then the signal frequency band corresponding to the second type of signal frequency is used to perform the attraction operation on the target terminal device. The signal frequency band corresponding to the first type of signal frequency is higher than the signal frequency band corresponding to the second type of signal frequency.

[0010] If the first type of signal frequency is not included in the first public network frequency information, then the signal frequency band corresponding to the second type of signal frequency is used to perform the target terminal device attraction operation.

[0011] As can be seen, in this embodiment, the first public network frequency information within the current signal coverage area is obtained, and it is determined whether the first public network frequency information includes a first type of signal frequency. If the first public network frequency information includes a first type of signal frequency, the network frequency information connecting the target terminal device to the public network base station is obtained. If the network frequency information includes a first type of signal frequency, the target terminal device is attracted using the signal frequency band corresponding to the first type of signal frequency. If the network frequency information does not include a first type of signal frequency but includes a second type of signal frequency, the target terminal device is attracted using the signal frequency band corresponding to the second type of signal frequency. If the first public network frequency information does not include a first type of signal frequency, the target terminal device is attracted using the signal frequency band corresponding to the second type of signal frequency. By using the aforementioned method, the time for the detection device to attract the target terminal device is reduced, and the efficiency of the detection device in completing the attraction of the target terminal device is improved.

[0012] In a feasible embodiment, after performing an adsorption operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency point, the method further includes: after successfully performing the adsorption operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency point, obtaining the location information of the target terminal device; obtaining environmental information within the current signal coverage area; and determining whether the target terminal device has entered the signal blocking area of ​​the detection device based on the location information and environmental information, wherein the signal blocking area of ​​the detection device includes the presence of tall buildings on the communication path with the target terminal device.

[0013] If the target terminal device enters the signal blocking area of ​​the detection device, determine whether there are other detection devices within the first area of ​​the target terminal device. The first area is determined based on the signal coverage area of ​​the detection device. If there are other detection devices within the first area of ​​the target terminal device, identify the target detection device among the other detection devices. The target detection device is the detection device whose signal blocking area the target terminal device has not entered. Send a first message to the soldier connected to the detection device. The first message prompts the soldier to send an instruction message to the target detection device. The instruction message instructs the soldier to attach the target terminal device through the target detection device. Receive release information from the soldier and release the target terminal device according to the release information.

[0014] In this embodiment, after successfully attaching the target terminal device using the signal frequency band corresponding to the first type of signal frequency point, it is determined whether the target terminal device has entered the signal blocking area of ​​the detection device based on the location information of the target terminal device and the environmental information within the current signal coverage area of ​​the detection device. If the target terminal device has entered the signal blocking area of ​​the detection device, the target detection device is identified based on other detection devices existing within the first area of ​​the target terminal device. The target detection device is the one where the target terminal device has not entered its signal blocking area. A first message instructing the soldier connected to the detection device to attach the target terminal device is sent. Upon receiving release information from the soldier, the target terminal device is released. Using the aforementioned method, the communication rate with the target terminal device can be guaranteed, thereby facilitating the tracking of the user of the target terminal device.

[0015] In a feasible embodiment, the method further includes: if there are no other detection devices within the first area of ​​the target terminal device, then determining whether there is a public network base station within the second area of ​​the target terminal device; if there is no public network base station within the second area of ​​the target terminal device, then switching to the signal frequency band corresponding to the second type of signal frequency point to perform an attraction operation on the target terminal device, wherein the second area is smaller than the first area; if there is a public network base station within the second area of ​​the target terminal device, then acquiring the second public network frequency point signal corresponding to the public network base station; if the second public network frequency point signal does not include the first type of signal frequency point, then using the signal frequency band corresponding to the second type of signal frequency point to perform an attraction operation on the target terminal device.

[0016] In this embodiment, if no other detection devices are present in the first area surrounding the target terminal device, it is determined whether a public network base station exists in the second area surrounding the target terminal. If no public network base station exists, or if the public network frequency signals propagated by the public network base station do not include the first type of signal frequency, the target terminal device is attracted using the signal frequency band corresponding to the second type of signal frequency. Using the aforementioned method can improve the stability of the communication connection with the terminal device.

[0017] In a feasible embodiment, after performing the attraction operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency point, the method further includes: if the attraction operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency point fails, sending second information to the public network base station within the signal coverage range of the detection device, and performing the attraction operation on the target terminal device using the signal frequency band corresponding to the second type of signal frequency point, wherein the second information is used to instruct the public network base station to stop using the signal frequency band corresponding to the first type of signal frequency point within a first preset time.

[0018] In this embodiment, if the attempt to attach to the target terminal device using the signal frequency band corresponding to the first type of signal frequency point fails, a second message is sent to a public network base station within the signal coverage area of ​​the detection device. This causes the public network base station to stop using the signal frequency band corresponding to the first type of signal frequency point, and the detection device then attempts to attach to the target terminal device using the signal frequency band corresponding to the second type of signal frequency point. Using the aforementioned method, it is possible to ensure that the detection device completes the attachment operation to the target terminal device.

[0019] In one feasible embodiment, if the network frequency information does not include the first type of signal frequency but includes the second type of signal frequency, then after performing the attraction operation on the target terminal device using the signal frequency band corresponding to the second type of signal frequency, the method further includes: after successfully performing the attraction operation on the target terminal device using the signal frequency band corresponding to the second type of signal frequency, obtaining the location information of the target terminal device; if it is determined that the target terminal device is in a moving state based on the location information of the target terminal device, obtaining interactive information sent from the target terminal device; if it is determined that the target terminal device is not in use based on the interactive information, then performing the attraction operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency.

[0020] In this embodiment, after successfully attaching to the target terminal device using the signal frequency band corresponding to the second type of signal frequency point, if it is determined that the target terminal device is not in use based on its location information and the interaction information sent by the target terminal device, then the target terminal device is attached using the signal frequency band corresponding to the first type of signal frequency point. Using the aforementioned method, while preventing users of the target terminal device from becoming alerted by signal frequency band switching, the data transmission rate between the detection device and the target terminal device can be increased, thereby improving the tracking success rate.

[0021] In a feasible embodiment, if the first type of signal frequency is not included in the first public network frequency information, then after using the signal frequency band corresponding to the second type of signal frequency to perform the adsorption operation on the target terminal device, the method further includes: after successfully performing the adsorption operation on the target terminal device using the signal frequency band corresponding to the second type of signal frequency, obtaining an adsorption record of the target terminal device; if it is determined from the adsorption record that the number of adsorptions on the target terminal device exceeds a first preset threshold, determining from the adsorption record whether the adsorption frequency band of the target terminal device includes the signal frequency band corresponding to the first type of signal frequency; if the adsorption frequency band of the target terminal device includes the signal frequency band corresponding to the first type of signal frequency, then using the signal frequency band corresponding to the first type of signal frequency to perform the adsorption operation on the target terminal device.

[0022] In this embodiment, after successfully adsorbing the target terminal device using the signal frequency band corresponding to the second type of signal frequency point, if the adsorption record between the detection device and the target terminal device determines that the number of adsorption attempts exceeds a first preset threshold, and the adsorption record also determines that the adsorption frequency band of the detection device on the target terminal device includes the signal frequency band corresponding to the first type of signal frequency point, then the adsorption operation on the target terminal device is performed using the signal frequency band corresponding to the first type of signal frequency point. Using the aforementioned method, the data transmission rate between the detection device and the target terminal device can be improved while ensuring the success rate of the detection device's adsorption of the target terminal device.

[0023] In one feasible embodiment, the method further includes: determining the number of first terminals attracted using the signal frequency band corresponding to the first type of signal frequency point, and the number of second terminals attracted using the signal frequency band corresponding to the second type of signal frequency point; determining whether a first condition is met, the first condition including at least one of the following: the difference between the number of first terminals and the number of second terminals is greater than a second preset threshold; the remaining usable battery power of the detection device is less than a third preset threshold; if the first condition is met, sending second information to the public network base station within the signal coverage area of ​​the detection device, the second information being used to instruct the public network base station to stop using the signal frequency band corresponding to the first type of signal frequency point within a first preset time; releasing the preset number of terminals attracted by the first type of signal frequency point, and attracting the preset number of terminals using the signal frequency band corresponding to the second type of signal frequency point, the preset number being determined based on the difference between the number of first terminals and the number of second terminals.

[0024] In this embodiment, the number of first terminals attracted using the signal band corresponding to the first type of signal frequency point and the number of second terminals attracted using the signal band corresponding to the second type of signal frequency point are determined. When the difference between the number of first terminals and the number of second terminals is greater than a second preset threshold, or when the remaining usable battery power of the detection device is less than a third preset threshold, third information is sent to the public network base station within the signal coverage area of ​​the detection device. This information instructs the public network base station to stop using the signal band corresponding to the first type of signal frequency point within a second preset time, release the preset number of terminals attracted by the first type of signal frequency point, and attract the preset number of terminals using the signal band corresponding to the second type of signal frequency point. By using the aforementioned method, a balance can be maintained between the number of terminals attracted by the signal band corresponding to the first type of signal frequency point and the number of terminals attracted by the signal band corresponding to the second type of signal frequency point in the detection device, thereby maintaining the overall power consumption balance of the detection device.

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0045] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps is not limited to the steps listed, but may optionally include steps not listed, or may optionally include other steps inherent to these processes, methods, products, or apparatuses.

[0046] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0047] This application plan is being implemented in accordance with the law and under official authorization.

[0048] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a code detection frequency band switching system provided in an embodiment of this application, as shown below. Figure 1 As shown, the code detection frequency band switching system includes a code detection device 101, a public network base station 102, and a terminal device 103. When conducting network communication, the terminal device 103 will preferentially select the highest frequency band signal that it can access. If the code detection device 101 wants to communicate with the terminal device 103, it needs to use the same frequency band as the signal frequency band propagated by the public network base station 102 to communicate with the terminal device 103, or use a higher frequency band than the signal frequency band propagated by the public network base station 102 to communicate with the terminal device 103.

[0049] Based on this, the present application provides a method for switching detection code frequency bands. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0050] Please see Figure 2 , Figure 2 This is a flowchart illustrating a code detection frequency band switching method provided in an embodiment of this application. This code detection frequency band switching method is applied to a code detection device, such as... Figure 2 As shown, the method includes the following steps:

[0051] Step 201: Obtain the first public network frequency point information within the current signal coverage area, and determine whether the first public network frequency point information includes the first type of signal frequency point.

[0052] The signal strength of the detection device must be stronger than that of the public network base station. Multiple public network base stations may exist within the signal coverage area of ​​the detection device, and the first public network frequency point information refers to the signal frequency points corresponding to the signals propagated by these multiple public network base stations. The first type of signal frequency point refers to the signal frequency point within the first type of signal frequency band.

[0053] Step 202: If the first public network frequency information includes the first type of signal frequency, obtain the network frequency information of the communication connection between the target terminal device and the public network base station.

[0054] The target terminal device is a terminal device within the target area of ​​the detection device. This target area can be the current signal coverage area of ​​the detection device, or a portion of the current signal coverage area. When the first public network frequency point information includes the first type of signal frequency point, it is also necessary to determine the signal frequency bands that the target terminal device itself can access. That is, the upper limit of the signal frequency bands that transmit signals through public network base stations, and the upper limit of the signal frequency bands that the target terminal itself can access, jointly determine the signal frequency bands for communication between the detection device and the target terminal device.

[0055] Step 203: If the network frequency information includes a first type of signal frequency, then the target terminal device is attracted using the signal frequency band corresponding to the first type of signal frequency.

[0056] Among them, the current network frequency signals include the first type of signal frequency points. The target terminal device will prioritize connecting according to the signal frequency band corresponding to the first type of signal frequency points. Therefore, the detection device also needs to use the signal frequency band corresponding to the first type of signal frequency points to communicate with it.

[0057] In a feasible embodiment, after performing an adsorption operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency point, the method further includes: after successfully performing the adsorption operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency point, obtaining the location information of the target terminal device; obtaining environmental information within the current signal coverage area; and determining whether the target terminal device has entered the signal blocking area of ​​the detection device based on the location information and environmental information, wherein the signal blocking area of ​​the detection device includes the presence of tall buildings on the communication path with the target terminal device.

[0058] If the target terminal device enters the signal blocking area of ​​the detection device, determine whether there are other detection devices within the first area of ​​the target terminal device. The first area is determined based on the signal coverage area of ​​the detection device. If there are other detection devices within the first area of ​​the target terminal device, identify the target detection device among the other detection devices. The target detection device is the detection device whose signal blocking area the target terminal device has not entered. Send a first message to the soldier connected to the detection device. The first message prompts the soldier to send an instruction message to the target detection device. The instruction message instructs the soldier to attach the target terminal device through the target detection device. Receive release information from the soldier and release the target terminal device according to the release information.

[0059] In most cases, the purpose of attaching the target terminal is to assist personnel in tracking the user of the target terminal device using individual soldiers. Specifically, when the detection device attaches to the target terminal device, it simultaneously establishes a communication connection with the individual soldier and periodically sends the device information to them. The user of the target terminal device may be constantly moving and may choose to enter building complexes to evade tracking. Compared to the second type of signal, the first type of signal has a higher frequency band and faster communication speed. When the detection device attaches to the target terminal device, it will also prioritize using the signal band corresponding to the first type of signal frequency. However, the first type of signal has the disadvantage of weak penetration and is easily blocked.

[0060] To prevent users of the target terminal device from evading tracking, this implementation continuously acquires the location information of the target terminal device and determines whether the target terminal device has entered a signal-blocking area based on environmental information within the current signal coverage area of ​​the detection device. A signal-blocking area refers to an area where tall buildings exist along the communication path to the target terminal device. Tall buildings can refer to a cluster of tall buildings or a single building that can block the communication path of the detection device.

[0061] The signal coverage areas of different detection devices may overlap, meaning that multiple detection devices may be able to communicate with a target terminal device in a given area. However, the targeting operation of a detection device on a target terminal device can originate from instructions from a backend server or other devices. When it is determined, based on the target terminal device's location information and environmental information within the current signal coverage area of ​​the detection device, that the target terminal device has entered a signal-blocking area, the system determines whether other detection devices exist within the target terminal device's first area. If other detection devices are found within the target terminal device's first area, the target detection device is identified from among these other devices. The target detection device is one whose signal-blocking area is not currently blocked by the target terminal device, and the size of the first area is not larger than the current signal coverage area of ​​the detection device.

[0062] In this embodiment, the soldier cannot know the connection status between the current detection device and the target terminal device, and the attachment of the detection device to the target terminal device also requires authorization from the backend server or other devices. Therefore, when the detection device determines that the communication signal between the target detection device and the target terminal device is stronger than the communication signal between the current detection device and the target terminal device, the detection device will send a first message to the soldier, instructing the soldier to connect to the target terminal device through the target detection device. At this time, the soldier will also issue an instruction to the target detection device to perform an attachment operation on the target terminal device through other means. Simultaneously, the soldier will also send a release message to the current detection device to release the target terminal device so that the target detection device can attach to it.

[0063] For example, please refer to Figure 3 , Figure 3 A structural schematic diagram of a high-rise building provided as an embodiment of this application, such as... Figure 3 As shown, Figure 3The system includes a first detection device 301, a second detection device 302, and a third detection device 303. All three detection devices are located within a first area of ​​the target terminal device 310. Currently, the first detection device 301 is in communication with the target terminal device 310. The target terminal device 310 has entered the signal blocking area of ​​the first detection device 301, which is the high-rise building area between the communication path of the target terminal device 310 and the first detection device 301. Although the second detection device 302 and the third detection device 303 also exist within the first area of ​​the target terminal device, the target terminal device 310 is also located in the signal blocking area of ​​the second detection device 302, but not in the signal blocking area of ​​the third detection device 303. Therefore, the third detection device 303 is selected as the target detection device.

[0064] In this embodiment, after successfully attaching the target terminal device using the signal frequency band corresponding to the first type of signal frequency point, it is determined whether the target terminal device has entered the signal blocking area of ​​the detection device based on the location information of the target terminal device and the environmental information within the current signal coverage area of ​​the detection device. If the target terminal device has entered the signal blocking area of ​​the detection device, the target detection device is identified based on other detection devices existing within the first area of ​​the target terminal device. The target detection device is the one where the target terminal device has not entered its signal blocking area. A first message instructing the soldier connected to the detection device to attach the target terminal device is sent. Upon receiving release information from the soldier, the target terminal device is released. Using the aforementioned method, the communication rate with the target terminal device can be guaranteed, thereby facilitating the tracking of the user of the target terminal device.

[0065] In addition, in a feasible embodiment, the method further includes: if there are no other detection devices in the first area of ​​the target terminal device, then determining whether there is a public network base station in the second area of ​​the target terminal device; if there is no public network base station in the second area of ​​the target terminal device, then switching to the signal frequency band corresponding to the second type of signal frequency point to perform an attraction operation on the target terminal device, wherein the second area is smaller than the first area; if there is a public network base station in the second area of ​​the target terminal device, then obtaining the second public network frequency point signal corresponding to the public network base station; if the second public network frequency point signal does not include the first type of signal frequency point, then using the signal frequency band corresponding to the second type of signal frequency point to perform an attraction operation on the target terminal device.

[0066] When no other detection devices are present within the first area surrounding the target terminal device, it is impossible to switch to another detection device with a stronger signal to establish a communication connection with the target terminal device. Since the signal frequency band corresponding to the second type of signal is lower than that corresponding to the first type of signal, but the second type of signal has stronger penetration capabilities, switching from the first type of signal frequency band to the second type of signal frequency band can be considered when obstruction exists. However, the target terminal device will preferentially access signals with higher frequency bands. Therefore, before switching to the second type of signal frequency band, it is necessary to consider whether other public network base stations within the second area surrounding the target terminal device might connect to it. The second area can be the signal coverage area of ​​a public network base station, while the signal coverage area of ​​the detection device is larger than that of the public base station; therefore, the second area is smaller than the first area.

[0067] When it is determined that a public network base station exists in the second area surrounding the target terminal device, it is also necessary to determine whether the frequency points of the signals propagated by the public network base station include the first type of signal frequencies. Only if the frequency points of the signals propagated by the public network base station do not include the first type of signal frequencies can the signal frequency bands corresponding to the second type of signal frequencies be used to attract the target terminal. Otherwise, the target terminal will preferentially choose to access the first type of signal propagated by the public network base station, and will not access the second type of signal propagated by the detection device.

[0068] In this embodiment, if no other detection devices are present in the first area surrounding the target terminal device, it is determined whether a public network base station exists in the second area surrounding the target terminal. If no public network base station exists, or if the public network frequency signals propagated by the public network base station do not include the first type of signal frequency, the target terminal device is attracted using the signal frequency band corresponding to the second type of signal frequency. Using the aforementioned method can improve the stability of the communication connection with the terminal device.

[0069] In a feasible embodiment, after performing the attraction operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency point, the method further includes: if the attraction operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency point fails, sending second information to the public network base station within the signal coverage range of the detection device, and performing the attraction operation on the target terminal device using the signal frequency band corresponding to the second type of signal frequency point, wherein the second information is used to instruct the public network base station to stop using the signal frequency band corresponding to the first type of signal frequency point within a first preset time.

[0070] When the attempt to connect with the target terminal device via the signal frequency band corresponding to the first type of signal frequency fails, the reason may be that the distance between the detection device and the target terminal device is much greater than the distance between the public network base station and the target terminal device, or that there are obstructions on the communication path between the detection device and the target terminal device, while there are no obstructions on the communication path between the public network base station and the target terminal device. In this case, the detection device cannot establish a communication connection with the target terminal device via the signal frequency band corresponding to the first type of signal frequency, nor can it directly establish a communication connection via the signal frequency band corresponding to the second type of signal frequency. In this embodiment, the detection device sends a second message to the public network base station within the signal coverage area to cause the public network base station to stop using the signal frequency band corresponding to the first type of signal frequency. At this time, the signal frequency band corresponding to the second type of signal frequency can be used to connect with the target terminal device.

[0071] In this embodiment, if the attempt to attach to the target terminal device using the signal frequency band corresponding to the first type of signal frequency point fails, a second message is sent to a public network base station within the signal coverage area of ​​the detection device. This causes the public network base station to stop using the signal frequency band corresponding to the first type of signal frequency point, and the detection device then attempts to attach to the target terminal device using the signal frequency band corresponding to the second type of signal frequency point. Using the aforementioned method, it is possible to ensure that the detection device completes the attachment operation to the target terminal device.

[0072] Step 204: If the network frequency information does not include the first type of signal frequency but includes the second type of signal frequency, then the target terminal device is attracted using the signal frequency band corresponding to the second type of signal frequency.

[0073] In this embodiment, the signal frequency band corresponding to the first type of signal frequency point is higher than that corresponding to the second type of signal frequency point. For example, the first type of signal frequency point can be a 5G signal frequency point, while the corresponding second type of signal frequency point can be a 4G signal frequency point. The first type of signal frequency point can also be other higher frequency bands, such as 6G signal frequency points; correspondingly, the second type of signal frequency point can be a 5G or 4G signal frequency point. This application does not limit the scope of the embodiments.

[0074] In one feasible embodiment, if the network frequency information does not include the first type of signal frequency but includes the second type of signal frequency, then after performing the attraction operation on the target terminal device using the signal frequency band corresponding to the second type of signal frequency, the method further includes: after successfully performing the attraction operation on the target terminal device using the signal frequency band corresponding to the second type of signal frequency, obtaining the location information of the target terminal device; if it is determined from the location information of the target terminal device that the target terminal device is in a moving state, obtaining interactive information sent from the target terminal device; if it is determined from the interactive information that the target terminal device is not in a usage state, then performing the attraction operation on the target terminal device using the signal frequency band corresponding to the first type of signal frequency.

[0075] If the network frequency information does not include Category 1 signal frequencies but does include Category 2 signal frequencies, it means that the target terminal device can only connect to Category 2 signals, or that the target terminal device can connect to Category 1 signals but cannot connect successfully due to the weakness of Category 1 signals. In this case, the detection device will first use the signal frequency corresponding to the Category 2 signal frequencies to perform an attraction operation on the target terminal device.

[0076] After successfully attaching to the target terminal device using the signal frequency band corresponding to the second type of signal frequency, the location information of the target terminal device is used to determine whether it is in motion. If the target terminal device is in motion, the interaction information between the target terminal device and the detection device is also used to determine whether it is in use. In this embodiment, determining whether the target terminal device is in use through interaction information mainly involves checking for the presence of a network card address. If no network card address is found, it can be determined that the target terminal device is not in use. At this point, using the signal frequency band corresponding to the first type of signal frequency to attach to the target terminal device is also to prevent changes in the signal frequency band from alerting the user while they are using their mobile phone. Successfully attaching to the target terminal device using the signal frequency band corresponding to the first type of signal frequency increases the data transmission rate, thereby improving the tracking success rate.

[0077] In addition, the speed or direction of movement of the target terminal device can be used to determine whether the user is escaping pursuit. For example, excessively high speed or frequent changes in direction can preliminarily indicate that the user is trying to escape. In this case, the signal frequency band corresponding to the first type of signal frequency can be used to attract the target terminal device. This improves the data transmission rate with the target terminal device, allowing staff to obtain a clearer escape route and increasing the success rate of tracking.

[0078] In this embodiment, after successfully attaching to the target terminal device using the signal frequency band corresponding to the second type of signal frequency point, if it is determined that the target terminal device is not in use based on its location information and the interaction information sent by the target terminal device, then the target terminal device is attached using the signal frequency band corresponding to the first type of signal frequency point. Using the aforementioned method, while preventing users of the target terminal device from becoming alerted by signal frequency band switching, the data transmission rate between the detection device and the target terminal device can be increased, thereby improving the tracking success rate.

[0079] Step 205: If the first type of signal frequency is not included in the first public network frequency information, the target terminal device is attracted using the signal frequency band corresponding to the second type of signal frequency.

[0080] If the first public network frequency information does not include the first type of signal frequency, it can be preliminarily determined that the current environment is not suitable for communication via the first type of signal. In this case, the detection device will immediately select the signal band corresponding to the second type of signal frequency to perform a targeting operation on the target terminal device, avoiding excessive time wasted before the targeting operation.

[0081] In a feasible embodiment, if the first type of signal frequency is not included in the first public network frequency information, then after using the signal frequency band corresponding to the second type of signal frequency to perform the adsorption operation on the target terminal device, the method further includes: after successfully performing the adsorption operation on the target terminal device using the signal frequency band corresponding to the second type of signal frequency, obtaining an adsorption record of the target terminal device; if it is determined from the adsorption record that the number of adsorptions on the target terminal device exceeds a first preset threshold, determining from the adsorption record whether the adsorption frequency band of the target terminal device includes the signal frequency band corresponding to the first type of signal frequency; if the adsorption frequency band of the target terminal device includes the signal frequency band corresponding to the first type of signal frequency, then using the signal frequency band corresponding to the first type of signal frequency to perform the adsorption operation on the target terminal device.

[0082] In this embodiment, after completing one adsorption operation on the target terminal device, subsequent adsorption operations with the target terminal device will take less time. Therefore, after successfully adsorbing the target terminal device using the signal frequency band corresponding to the second type of signal frequency, it is possible to consider whether to switch to the first type of signal to establish a communication connection with the target terminal device. This embodiment determines the adsorption record with the target terminal device based on the device identification code of the target terminal device. When the adsorption record determines that the number of adsorption operations between the detection device and the target terminal device exceeds a first preset threshold, the adsorption record can serve as a reference. Furthermore, it is determined based on the adsorption record whether the adsorption frequency band with the target terminal device includes the signal frequency band corresponding to the first type of signal frequency. If the adsorption frequency band with the target terminal device includes the signal frequency band corresponding to the first type of signal frequency, it indicates that the target terminal device itself can access the first type of signal, and in this case, the signal frequency band corresponding to the first type of signal frequency can be selected for adsorption operations on the target terminal device.

[0083] For example, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of an adsorption recording table provided in an embodiment of this application, as shown below. Figure 4 As shown, Figure 4 This includes an adsorption record table, which records the adsorption status of the detection device over a certain period of time, mainly including the device identification code of the adsorption terminal, the adsorption time, and the adsorption frequency. In this embodiment, the number of adsorption cycles for the target terminal device can be the number of adsorption records determined in the adsorption record table based on the device identification code of the target terminal device.

[0084] In this embodiment, after successfully adsorbing the target terminal device using the signal frequency band corresponding to the second type of signal frequency point, if the adsorption record between the detection device and the target terminal device determines that the number of adsorption attempts exceeds a first preset threshold, and the adsorption record also determines that the adsorption frequency band of the detection device on the target terminal device includes the signal frequency band corresponding to the first type of signal frequency point, then the adsorption operation on the target terminal device is performed using the signal frequency band corresponding to the first type of signal frequency point. Using the aforementioned method, the data transmission rate between the detection device and the target terminal device can be improved while ensuring the success rate of the detection device's adsorption of the target terminal device.

[0085] In one feasible embodiment, the method further includes: determining the number of first terminals attracted using the signal frequency band corresponding to the first type of signal frequency point, and the number of second terminals attracted using the signal frequency band corresponding to the second type of signal frequency point; determining whether a first condition is met, the first condition including at least one of the following: the difference between the number of first terminals and the number of second terminals is greater than a second preset threshold; the remaining usable battery power of the detection device is less than a third preset threshold; if the first condition is met, sending second information to the public network base station within the signal coverage area of ​​the detection device, the second information being used to instruct the public network base station to stop using the signal frequency band corresponding to the first type of signal frequency point within a first preset time; releasing the preset number of terminals attracted by the first type of signal frequency point, and attracting the preset number of terminals using the signal frequency band corresponding to the second type of signal frequency point, the preset number being determined based on the difference between the number of first terminals and the number of second terminals.

[0086] While using the signal frequency band corresponding to the first type of signal frequency to attract target terminal devices offers high speed and low latency, it also increases the power consumption of the detection device. If, with the total number of devices attracted by the detection device remaining constant, the number of first terminals attracted using the signal frequency band corresponding to the first type of signal frequency is significantly greater than the number of second terminals attracted using the signal frequency band corresponding to the second type of signal frequency, it leads to an imbalance in the internal power consumption of the detection device, greatly increasing its power consumption.

[0087] Therefore, when the number of the first type of terminals is much greater than the number of the second type of terminals, or when the remaining battery power of the detection device is low, the detection device will release a preset number of terminals attracted using the first type of signal frequency and re-attract them using the signal frequency band corresponding to the second type of signal frequency. The preset number is determined based on the difference between the number of the first type of terminals and the number of the second type of terminals, with the aim of maintaining a balance between the two numbers. Before this, a third message needs to be sent to the public network base stations within the signal coverage area of ​​the detection device to instruct the public network base stations to stop using the signal frequency band corresponding to the first type of signal frequency within a second preset time. The second preset time can be determined based on historical attraction data, specifically based on the attraction duration of each terminal device.

[0088] In addition, the number of terminal devices that can be attracted by the signal frequency band corresponding to the first type of signal frequency point can be determined based on the overall power consumption of the detection equipment. That is, the number of terminal devices attracted by the signal frequency band corresponding to the first type of signal frequency point can be determined based on the total number of terminals attracted by the detection equipment. If the total number of attracted terminals is large, then the number of terminal devices attracted by the signal frequency band corresponding to the first type of signal frequency point can be relatively small; if the total number of attracted terminals is small, then the number of terminal devices attracted by the signal frequency band corresponding to the first type of signal frequency point can be relatively large.

[0089] In this embodiment, the number of first terminals attracted using the signal band corresponding to the first type of signal frequency point and the number of second terminals attracted using the signal band corresponding to the second type of signal frequency point are determined. When the difference between the number of first terminals and the number of second terminals is greater than a second preset threshold, or when the remaining usable battery power of the detection device is less than a third preset threshold, third information is sent to the public network base station within the signal coverage area of ​​the detection device. This information instructs the public network base station to stop using the signal band corresponding to the first type of signal frequency point within a second preset time, release the preset number of terminals attracted by the first type of signal frequency point, and attract the preset number of terminals using the signal band corresponding to the second type of signal frequency point. By using the aforementioned method, a balance can be maintained between the number of terminals attracted by the signal band corresponding to the first type of signal frequency point and the number of terminals attracted by the signal band corresponding to the second type of signal frequency point in the detection device, thereby maintaining the overall power consumption balance of the detection device.

[0090] As can be seen, in this embodiment, the first public network frequency information within the current signal coverage area is obtained, and it is determined whether the first public network frequency information includes a first type of signal frequency. If the first public network frequency information includes a first type of signal frequency, the network frequency information connecting the target terminal device to the public network base station is obtained. If the network frequency information includes a first type of signal frequency, the target terminal device is attracted using the signal frequency band corresponding to the first type of signal frequency. If the network frequency information does not include a first type of signal frequency but includes a second type of signal frequency, the target terminal device is attracted using the signal frequency band corresponding to the second type of signal frequency. If the first public network frequency information does not include a first type of signal frequency, the target terminal device is attracted using the signal frequency band corresponding to the second type of signal frequency. By using the aforementioned method, the time for the detection device to attract the target terminal device is reduced, and the efficiency of the detection device in completing the attraction of the target terminal device is improved.
