Description

Technical Field

[0001] This application relates to the field of general data processing technology, and in particular to a signaling processing method and apparatus based on an adsorbed terminal. Background Technology

[0002] Currently, detection devices are mainly used for target location tracking. Specifically, the device is attached to the target's mobile phone, and its location is achieved with the assistance of individual surveillance personnel. However, during the attachment process, the mobile phone cannot connect to a public network base station, resulting in a lack of network signal. This may cause the target to become wary due to the lack of network connectivity and detach from the phone, increasing the difficulty of target location tracking. Therefore, continuously attaching the detection device to the target's mobile phone may negatively impact the location process. Summary of the Invention

[0003] This application provides a signaling processing method and apparatus based on an adsorbed terminal. By judging the usage status of the target terminal by the tracking target, the method dynamically adsorbs or releases the target terminal, thereby reducing the tracking target's vigilance during the use of the target terminal and improving the success rate of locating and tracking the target.

[0004] In a first aspect, embodiments of this application provide a signaling processing method based on an adsorbed terminal, which is applied to a code detection device. The method includes:

[0005] The target terminal is attracted and a wireless communication connection is maintained with the individual soldier's main station control terminal.

[0006] After successfully attaching to the target terminal, the system sends a first message to the target terminal, which is used to request the network card address of the target terminal.

[0007] Receive the first response information from the individual soldier's master station control terminal. The first response information is used to indicate whether the network card address of the target terminal has been found.

[0008] If the first response information is an acknowledgment character (ACK) message, then a second message is sent to the individual soldier's master station control terminal. The second message is used to request an instruction on whether to release the target terminal.

[0009] Receive the second response information from the individual soldier's master station control terminal, and perform a detection operation on the target terminal based on the second response information. The detection operation includes releasing the target terminal or attaching the target terminal.

[0010] As can be seen, in this embodiment, the target terminal is attracted while maintaining a wireless communication connection with the soldier's master station control terminal. After successfully attracting the target terminal, a first message is sent to the target terminal. A first response message is received from the soldier's master station control terminal. If the first response message is an ACK message, a second message is sent to the soldier's master station control terminal. A second response message is received from the soldier's master station control terminal, and a detection operation is performed on the target terminal based on the second response message. The detection operation includes releasing the target terminal or attracting the target terminal. By using the aforementioned method, the target terminal is dynamically attracted or released based on the target's usage status, which can reduce the target's vigilance during the use of the target terminal, thereby improving the success rate of locating and tracking the target.

[0011] In one feasible embodiment, performing a detection operation on the target terminal based on the second response information includes: if the second response information includes an indication not to release the target terminal, then maintaining the attachment to the target terminal; if the second response information includes an indication to release the target terminal, then releasing the target terminal; after releasing the target terminal, the method further includes: increasing the priority of receiving messages from the soldier's master station control terminal; receiving first indication information from the soldier's master station control terminal, the first indication information being used to indicate the attachment of the target terminal; adjusting the communication connection with the target terminal to the highest priority, and performing the attachment operation on the target terminal at the highest priority.

[0012] In this embodiment, the target terminal is either attracted or released based on the second response information. After releasing the target terminal, the priority of receiving messages from the soldier's master station control terminal is increased, and the communication connection with the target terminal is adjusted to the highest priority. Upon receiving the first instruction message from the soldier's master station control terminal, the target terminal is attracted. Using the aforementioned method can improve the success rate of target location and tracking.

[0013] In a feasible embodiment, the detection operation for the target terminal is performed according to the second response information, including: if the second response information includes an instruction to release the target terminal, then the target terminal is released; if the second response information includes an instruction not to release the target terminal, then the number of network access requests of the target terminal is obtained, and it is determined whether the network access requests of the target terminal satisfy at least one of the following: the number of network access requests of the target terminal is greater than a first preset number; or the interval between adjacent network access requests of the target terminal is less than a first preset interval; if the access requests of the target terminal satisfy at least one of the following, then the target terminal is released according to a preset period, wherein the time for releasing the target terminal within a preset period is half a preset period, and the network access record of the target terminal is sent to the main station control terminal of the individual soldier.

[0014] In this embodiment, the target terminal is either attracted or released based on the second response information. When the target terminal is not released, the number of network access requests made by the target terminal is obtained. If the number of network access requests exceeds a first preset number or the interval between adjacent network access requests is less than a first preset interval, the target terminal is released according to a preset period. Within one preset period, the time for releasing the target terminal is half a preset period, and the network access record is sent to the individual soldier's main station control terminal. Using the aforementioned method, the usage status of the target terminal by the tracking target can be determined in a timely and effective manner, and the target terminal can be released or attracted accordingly, thereby reducing the vigilance of the tracking target due to the inability to use the target terminal.

[0015] In a feasible embodiment, after releasing the target terminal according to a preset period, the method further includes: obtaining the usage record of the target terminal, the usage record including the usage time within a first preset duration; determining the average daily usage time of the target terminal, a first time period and a second time period based on the usage record of the target terminal, the first time period being the time period with the highest daily usage frequency of the target terminal, and the second time period being the time period with the lowest daily usage frequency of the target terminal;

[0016] If the target terminal is currently in use during the first time period, the estimated remaining usage time of the target terminal is determined based on the target terminal's average daily usage time and the target terminal's current usage time.

[0017] If the target terminal is currently in the second time period, the estimated usage time of the target terminal is determined based on the average daily usage time of the target terminal and the first ratio, where the first ratio is the ratio of the second time period to the day. The estimated remaining usage time of the target terminal is determined based on the estimated usage time of the target terminal and the current usage time of the target terminal.

[0018] If the target terminal is not currently in the first or second time period, the estimated usage time of the target terminal is determined based on the average daily usage time of the target terminal and the second ratio. The second ratio is the ratio of the time period other than the first and second time periods in a day to the total time of a day. The estimated remaining usage time of the target terminal is determined based on the estimated usage time of the target terminal and the current usage time of the target terminal.

[0019] If the estimated remaining usage time of the target terminal is less than the second preset time, then the target terminal will be attached.

[0020] In this embodiment, after releasing the target terminal according to a preset cycle, the usage record of the target terminal is acquired, and the estimated remaining usage time of the target terminal is determined based on the usage record. When the estimated remaining usage time of the target terminal is less than a second preset time, the target terminal is attracted. Using the aforementioned method, during the dynamic release of the target terminal, since the target terminal cannot be located during release, attracting the target terminal based on its estimated remaining usage time allows for real-time location of the target terminal without raising suspicion of the tracking target's use of the target terminal, thus improving the success rate of target location and tracking.

[0021] In one feasible embodiment, the method further includes: if the first response information is a non-acknowledgement (NACK) character, determining the target terminal's movement status information based on the Manhattan distance of the target terminal, the movement status information including movement speed and movement direction; and sending third information to the soldier's master station control terminal, the third information carrying the target terminal's movement status information.

[0022] In this embodiment, the movement status information of the target terminal is determined by Manhattan distance, and this movement status information is sent to the individual soldier's main station control terminal. This allows investigators to monitor the movement status of the target terminal at all times and to determine the target terminal's location based on the movement status.

[0023] In a feasible embodiment, after determining the movement status information of the target terminal, the method further includes: determining that the target terminal is in an abnormal movement state if the movement status information of the target terminal meets a first condition, wherein the first condition includes at least one of the following: the movement speed of the target terminal is greater than a first preset threshold; or the movement direction of the target terminal changes more than a second preset threshold within a first preset time period; the third information also carries first prompt information, which is used to indicate that the target terminal is in an abnormal movement state.

[0024] In this embodiment, when the target terminal's moving speed exceeds a first preset threshold, or the target terminal's moving direction changes more than a second preset threshold within a first preset time period, it is sent to the individual soldier's main station control terminal. This can promptly alert investigators and improve the success rate of locating and tracking the target.

[0025] In one feasible embodiment, after sending the third information to the soldier's master station control terminal, the method further includes: receiving third response information from the soldier's master station control terminal, the third response information being used to indicate the frequency of increasing the transmission frequency of the target terminal's mobility status information; and transmitting the target terminal's mobility status information according to the third response information.

[0026] In this embodiment, upon receiving a third response message from the soldier's master station control terminal, the frequency of sending the target terminal's movement status information to the soldier's master station control terminal is increased. This allows investigators to more accurately grasp the target terminal's location information, improving the success rate of target location and tracking.

[0027] Secondly, embodiments of this application provide a signaling processing device based on an adsorbed terminal, which is applied to a code detection device. The device includes:

[0028] The processing unit is used to perform an adsorption operation on the target terminal and maintain a wireless communication connection with the individual soldier's main station control terminal.

[0029] After the processing unit successfully performs the adsorption operation on the target terminal, the sending unit sends first information to the target terminal, which is used to request the query of the target terminal's network card address.

[0030] The receiving unit is used to receive the first response information from the individual soldier's master station control terminal. The first response information is used to indicate whether the network card address of the target terminal has been found.

[0031] The sending unit is also used to send a second message to the main station control terminal of the individual soldier if the first response message is an ACK message. The second message is used to request an indication message on whether to release the target terminal.

[0032] The receiving unit is also used to receive second response information from the individual soldier's master station control terminal, and to perform a detection operation on the target terminal based on the second response information. The detection operation includes releasing the target terminal or attracting the target terminal.

[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] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a signaling processing system provided in an embodiment of this application, as shown below. Figure 1 As shown, the signaling processing system 100 includes a code detection device 101, a single-soldier master station control terminal 102, and a target terminal 103. The code detection device 101 is based on the principle of wireless communication base station technology. By simulating the broadcast inducement signal of the operator's mobile communication network (China Mobile / China Unicom / China Telecom), it provides a stronger signal than the public network base station, so that mobile phones or terminals in the surrounding standby state can detect the change in location area and initiate the location area update process to register with the code detection device 101 and report IMEI / IMSI (4G) or SUPI / SUCI (5G), thereby completing the collection of public network user terminal information in the coverage area.

[0048] In the signaling processing system, after the detection device 101 is attached to the target terminal 103, it periodically changes the tracking area code (TAC) to keep the target terminal 103 online for an extended period. Simultaneously, it continuously issues uplink authorizations, causing the target terminal 103 to continuously transmit uplink data. Meanwhile, the individual soldier's master station control terminal 102 uses a directional antenna to continuously measure the uplink signal strength of the target terminal 103. When the directional antenna is pointed towards the target terminal 103, the power is stronger than in other directions. Given that the signal strength of the individual soldier's master station control terminal 102 varies depending on its orientation at the same location, investigators control the individual soldier's master station control terminal 102 to continuously move closer to the target terminal 103 to achieve the positioning objective. The target terminal refers to a mobile terminal capable of communicating with public network base stations.

[0049] Based on this, the present application provides a signaling processing method based on the adsorbed terminal. 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 application provides a schematic flowchart of a signaling processing method based on an adsorbed terminal, which is applied to a code detection device. Figure 2 As shown, the method includes the following steps:

[0051] Step 201: Perform an adsorption operation on the target terminal and maintain a wireless communication connection with the soldier's main station control terminal.

[0052] Detection devices are typically fixed in a specific area. Therefore, before locating and tracking a target, it's necessary to determine the corresponding detection device. This can be done by obtaining the target's location through other means and then identifying the appropriate detection device based on that location. Alternatively, detection devices can be used simultaneously in multiple areas to search for the target terminal, ultimately identifying the detection device that finds the target terminal.

[0053] The target terminal attraction operation involves the detection device broadcasting inducement information simulating a mobile communication network operator, causing nearby terminals to register and report their device identification codes. The detection device scans the device identification codes of nearby terminals and compares them with the target terminal's device identification code to identify the target terminal. Once the target terminal is identified, it is locked, thus achieving continuous attraction to the target terminal. The detection device also wirelessly connects to the soldier's master station control terminal, transmitting the target terminal's location information to the soldier's master station control terminal, thereby assisting the soldier's master station control terminal in locating the target terminal.

[0054] For example, please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a code detection list provided in an embodiment of this application, as shown below. Figure 3 As shown, Figure 3 This includes a detection list from a detection device, containing device identification codes (such as IMSI codes) corresponding to terminals connected to different communication channels. The detection device compares the device identification codes of terminals connected to different channels with the target terminal's device identification code to determine the channel to which the target terminal is connected and maintains the channel connection to the target terminal. For ordinary terminals connected to other channels, the connection can be released.

[0055] Step 202: After successfully performing the adsorption operation on the target terminal, send the first message to the target terminal.

[0056] The first piece of information is used to request the network card address of the target terminal. After the detection device successfully attaches to the target terminal, if the target terminal is in a normal screen-off state (not in a call or background playback), the mobile phone's network card is not working, and the network card address information cannot be collected. However, when the screen is on, the mobile phone's network card is definitely working, and the network card address will definitely be included in the transmission message, i.e., it will be collected.

[0057] Step 203: Receive the first response information from the individual soldier's master station control terminal.

[0058] The first response information indicates whether the target terminal's network card address has been found. When the phone is in a normal, screen-off state (not on a call or playing content in the background), the target terminal's network card address cannot be found. However, when the phone screen is on, the network card address can be found. Therefore, the first response information can be used to determine whether the tracking target is currently using the target terminal. Based on the tracking target's usage status of the target terminal, the detection device can then perform the attraction or release operation on the target terminal.

[0059] Step 204: If the first response information is ACK information, then send the second information to the individual soldier's master station control terminal.

[0060] The second piece of information is used to request an indication of whether to release the target terminal. The ACK message indicates that the receiver has successfully received the data. When the network interface card (NIC) address query response is an ACK message, it means that the NIC address is included in the transmitted information, indicating that the target is currently using the target terminal.

[0061] Step 205: Receive the second response information from the individual soldier's master station control terminal, and perform a code detection operation on the target terminal based on the second response information.

[0062] The detection operation includes releasing or attaching the target terminal. The individual soldier's master station control terminal is carried by the investigators, who can use the second information received from the individual soldier's master station control terminal to determine whether to allow the detection device to release the target terminal.

[0063] Specifically, in one feasible embodiment, performing a detection operation on the target terminal based on the second response information includes: if the second response information includes an indication not to release the target terminal, then maintaining the attachment to the target terminal; if the second response information includes an indication to release the target terminal, then releasing the target terminal; after releasing the target terminal, the method further includes: increasing the priority of receiving messages from the soldier's master station control terminal; receiving first indication information from the soldier's master station control terminal, the first indication information being used to indicate the attachment of the target terminal; adjusting the communication connection with the target terminal to the highest priority, and performing the attachment operation on the target terminal with the highest priority.

[0064] In this process, after the detection device releases the target terminal based on the second response information from the soldier's master station control terminal, it needs to re-attach the target terminal at any time during the current positioning phase. The re-attachment of the target terminal is primarily based on instructions from the soldier's master station control terminal. Therefore, it is necessary to increase the priority of message reception from the soldier's master station control terminal to ensure that message processing is not delayed, and to increase the highest priority of the communication connection to the target terminal to ensure that the re-attachment operation is completed as quickly as possible upon receiving the first instruction information from the soldier's master station control terminal.

[0065] In this embodiment, the target terminal is either attracted or released based on the second response information. After releasing the target terminal, the priority of receiving messages from the soldier's master station control terminal is increased, and the communication connection with the target terminal is adjusted to the highest priority. Upon receiving the first instruction message from the soldier's master station control terminal, the target terminal is attracted. Using the aforementioned method can improve the success rate of target location and tracking.

[0066] In addition, in one feasible embodiment, the detection operation for the target terminal is performed according to the second response information, including: if the second response information includes an instruction to release the target terminal, then the target terminal is released; if the second response information includes an instruction not to release the target terminal, then the number of network access requests of the target terminal is obtained, and it is determined whether the network access requests of the target terminal satisfy at least one of the following: the number of network access requests of the target terminal is greater than a first preset number; or the interval between adjacent network access requests of the target terminal is less than a first preset interval; if the access requests of the target terminal satisfy at least one of the following, then the target terminal is released according to a preset period, wherein the time for releasing the target terminal within a preset period is half a preset period, and the network access record of the target terminal is sent to the main station control terminal of the individual soldier.

[0067] Since the individual soldier's master station control terminal is manually controlled, investigators may not have observed the target and therefore cannot know its current status. It is impossible to promptly and effectively issue instruction messages through the individual soldier's master station control terminal to enable the detection device to attach or release the target terminal. Therefore, in addition to releasing the target terminal based on instructions from the individual soldier's master station control terminal, this embodiment also dynamically releases or attaches the target terminal by judging its network access requests.

[0068] Since the detection device is attached to the target terminal, any network access requests made by the target when using their mobile phone will be transmitted to the detection device. If there are many network access requests or short intervals between adjacent requests, it indicates a high demand for network access from the target terminal. In this case, the target terminal can be released according to a preset cycle, with half of the cycle being released. During the remaining half cycle, the target terminal remains attached, putting it in a state of poor network connectivity, but not completely without network access, thus alleviating any suspicion from the tracking target. Simultaneously, the network access records are sent to the individual soldier's main control station, allowing investigators to monitor the target's current status.

[0069] However, if the target is in the process of making a call or using another target terminal that requires uninterrupted network access, frequent and periodic network interruptions may confuse the target. Therefore, in another feasible embodiment, network access requests are identified, and different strategies are applied to attract or release them based on the type of network request. For example, if the network access request is a call request, the target terminal is released; if the network access request is not a call request, the target terminal is released according to a preset period based on the strategy described in the above embodiment, i.e., when the number of network access requests is greater than a first preset number, or the interval between adjacent network access requests is less than a first preset interval. Within one preset period, the time for releasing the target terminal is half a preset period.

[0070] In this embodiment, the target terminal is either attracted or released based on the second response information. When the target terminal is not released, the number of network access requests made by the target terminal is obtained. When the number of network access requests exceeds a first preset number or the interval between adjacent network access requests is less than a first preset interval, the target terminal is released according to a preset period. Within one preset period, the time for releasing the target terminal is half a preset period, and the network access record is sent to the individual soldier's main station control terminal. Using the aforementioned method, the usage status of the target terminal by the tracking target can be determined in a timely and effective manner, and the target terminal can be released or attracted accordingly, thereby reducing the vigilance of the tracking target due to the inability to use the target terminal.

[0071] In addition, in a feasible embodiment, after releasing the target terminal according to a preset period, the method further includes: obtaining the usage record of the target terminal, the usage record including the usage time within a first preset duration; determining the average daily usage time of the target terminal, a first time period and a second time period based on the usage record of the target terminal, the first time period being the time period with the highest daily usage frequency of the target terminal, and the second time period being the time period with the lowest daily usage frequency of the target terminal;

[0072] If the target terminal is currently in use during the first time period, the estimated remaining usage time of the target terminal is determined based on the target terminal's average daily usage time and the target terminal's current usage time.

[0073] If the target terminal is currently in the second time period, the estimated usage time of the target terminal is determined based on the average daily usage time of the target terminal and the first ratio, where the first ratio is the ratio of the second time period to the day. The estimated remaining usage time of the target terminal is determined based on the estimated usage time of the target terminal and the current usage time of the target terminal.

[0074] If the target terminal is not currently in the first or second time period, the estimated usage time of the target terminal is determined based on the average daily usage time of the target terminal and the second ratio. The second ratio is the ratio of the time period other than the first and second time periods in a day to the total time of a day. The estimated remaining usage time of the target terminal is determined based on the estimated usage time of the target terminal and the current usage time of the target terminal.

[0075] If the estimated remaining usage time of the target terminal is less than the second preset time, then the target terminal will be attached.

[0076] In this embodiment, the detection device can only obtain the target terminal's location information when it is attached to the target terminal. Prolonged periodic release of the target terminal can affect its location tracking. This solution estimates the remaining usage time of the target terminal by tracking its usage habits. When the remaining usage time is short, the preset periodic release of the target terminal is stopped, and the target terminal is attached again.

[0077] Specifically, the system acquires the target terminal's usage records, including usage time within a first preset duration, such as a week's worth of mobile phone usage. Based on these records, it determines the average daily usage time, the highest-frequency first time period, and the lowest-frequency second time period. It then determines which time period the target terminal's current usage time falls into. If it falls into the first time period, the estimated remaining usage time is determined directly based on the average daily usage time and the current usage time. If it falls into the second time period, the estimated usage time is first determined by comparing the proportion of the second time period to the average daily usage time, and then the estimated remaining usage time is determined based on this estimated usage time. If it falls into a third time period other than the first and second time periods, the estimated usage time is determined by comparing the proportion of the third time period to the average daily usage time, and then the estimated remaining usage time is determined based on this estimated usage time. When the estimated remaining usage time is less than the second preset duration, the preset periodic release of the target terminal is stopped, and the target terminal is reactivated.

[0078] For example, if the first time period is [18:00-00:00], the second time period is [00:00-06:00], and the average daily usage time is 4 hours, the current usage time of the target terminal is 0.2 hours. If the current usage time period of the target terminal is the first time period, the estimated remaining usage time of the target terminal can be determined to be 3.8 hours; if the current usage time period of the target terminal is the second time period, the first proportion can be determined to be 25%, the estimated usage time of the target terminal is 1 hour, and the estimated remaining usage time of the target terminal is 0.8 hours; if the current usage time period of the target terminal is neither the first nor the second time period, but the third time period [06:00-18:00], the second proportion can be determined to be 50%, the estimated usage time of the target terminal is 2 hours, and the estimated remaining usage time of the target terminal is 1.8 hours.

[0079] In this embodiment, after releasing the target terminal according to a preset cycle, the usage record of the target terminal is acquired, and the estimated remaining usage time of the target terminal is determined based on the usage record. When the estimated remaining usage time of the target terminal is less than a second preset time, the target terminal is attracted. Using the aforementioned method, during the dynamic release of the target terminal, since the target terminal cannot be located during release, attracting the target terminal based on its estimated remaining usage time allows for real-time location of the target terminal without raising suspicion of the tracking target's use of the target terminal, thus improving the success rate of target location and tracking.

[0080] In one feasible embodiment, the method further includes: if the first response information is NACK information, determining the movement status information of the target terminal based on the Manhattan distance of the target terminal, the movement status information including movement speed and movement direction; and sending third information to the soldier's master station control terminal, the third information carrying the movement status information of the target terminal.

[0081] When the network card address query response is NACK, it indicates that the target terminal is in a normal screen-off state, meaning the target is not currently using the terminal and may be in a moving state. Therefore, this embodiment uses the Manhattan distance of the target terminal to determine its movement status. Manhattan distance refers to the distance the target terminal moves in the north-south and east-west directions. Since buildings are generally square, movement along streets between buildings tends to occur in the north-south and east-west directions. Therefore, in this embodiment, Manhattan distance is more suitable for determining the movement status of the target. This movement status information is understood to be based on a preset time period. After determining the target terminal's movement status information, it is sent to the individual soldier's main station control terminal.

[0082] In this embodiment, the movement status information of the target terminal is determined by Manhattan distance, and this movement status information is sent to the individual soldier's main station control terminal. This allows investigators to monitor the movement status of the target terminal at all times and to determine the target terminal's location based on the movement status.

[0083] In a feasible embodiment, after determining the movement status information of the target terminal, the method further includes: determining that the target terminal is in an abnormal movement state if the movement status information of the target terminal meets a first condition, wherein the first condition includes at least one of the following: the movement speed of the target terminal is greater than a first preset threshold; or the movement direction of the target terminal changes more than a second preset threshold within a first preset time period; the third information also carries first prompt information, which is used to indicate that the target terminal is in an abnormal movement state.

[0084] In this embodiment, when determining the movement status of a target terminal, the detection device also provides an initial warning. Specifically, if the target terminal moves too quickly or changes direction too frequently, it may be relocating to evade investigators. However, if investigators haven't detected the target, they won't be aware of its relocation, and by the time they realize it, the target may have already escaped. This embodiment provides an initial warning and timely alerts investigators.

[0085] For example, please refer to Figure 4, Figure 4 A schematic diagram of the structure of an urban route provided in this application embodiment, such as... Figure 4 As shown, Figure 4 The area includes multiple square buildings, with intersections 1, 2, and 3 located between them. Normally, traffic can travel from intersection 1 to intersection 2 as follows: Figure 4 The arrow indicates a straight line. However, if the target becomes wary of the target terminal's use, it may suspect it is being tracked. In this case, if the target wants to move from intersection 1 to intersection 2, it may consider changing its direction of movement to escape pursuit, such as... Figure 4 The middle arrow indicates the route from intersection 1 to intersection 3, and then from intersection 3 to intersection 2.

[0086] In this embodiment, when the target terminal's moving speed exceeds a first preset threshold, or the target terminal's moving direction changes more than a second preset threshold within a first preset time period, it is sent to the individual soldier's main station control terminal. This can promptly alert investigators and improve the success rate of locating and tracking the target.

[0087] In one feasible embodiment, after sending the third information to the soldier's master station control terminal, the method further includes: receiving third response information from the soldier's master station control terminal, the third response information being used to indicate the frequency of increasing the transmission frequency of the target terminal's mobility status information; and transmitting the target terminal's mobility status information according to the third response information.

[0088] In this embodiment, after the detection device sends the target terminal's movement status information to the soldier's main control station, if investigators intend to expedite the location process, the soldier's main control station will send a third response message to increase the frequency with which the detection device sends the target terminal's movement status information to the soldier's main control station. This allows investigators to more accurately determine the target terminal's location.

[0089] In this embodiment, upon receiving a third response message from the soldier's master station control terminal, the frequency of sending the target terminal's movement status information to the soldier's master station control terminal is increased. This allows investigators to more accurately grasp the target terminal's location information, improving the success rate of target location and tracking.

[0090] As can be seen, in this embodiment, the target terminal is attracted while maintaining a wireless communication connection with the soldier's master station control terminal. After successfully attracting the target terminal, a first message is sent to the target terminal. A first response message is received from the soldier's master station control terminal. If the first response message is an ACK message, a second message is sent to the soldier's master station control terminal. A second response message is received from the soldier's master station control terminal, and a detection operation is performed on the target terminal based on the second response message. The detection operation includes releasing the target terminal or attracting the target terminal. By using the aforementioned method, the target terminal is dynamically attracted or released based on the target's usage status, which can reduce the target's vigilance during the use of the target terminal, thereby improving the success rate of locating and tracking the target.

[0091] For embodiments consistent with those shown above, please refer to... Figure 5a , Figure 5a This is a functional unit block diagram of a signaling processing device based on an adsorbed terminal provided in an embodiment of this application, applied to a code detection device, such as... Figure 5a As shown, the signaling processing device 50 based on the adsorbed terminal includes:

[0092] The processing unit 501 is used to perform an adsorption operation on the target terminal and maintain a wireless communication connection with the soldier's main station control terminal.

[0093] After the processing unit 501 successfully performs the adsorption operation on the target terminal, the sending unit 502 sends first information to the target terminal, the first information being used to request a query of the target terminal's network card address.

[0094] The receiving unit 503 is used to receive first response information from the main station control terminal of the individual soldier. The first response information is used to indicate whether the network card address of the target terminal has been found.

[0095] The sending unit 502 is also used to send a second message to the main station control terminal of the individual soldier if the first response message is an ACK message. The second message is used to request an indication message on whether to release the target terminal.

[0096] The receiving unit 503 is also used to receive second response information from the main station control terminal of the individual soldier, and the processing unit 501 is used to perform a code detection operation on the target terminal according to the second response information.

[0099] In a feasible embodiment, after releasing the target terminal according to a preset period, the processing unit 501 is further configured to: obtain the usage record of the target terminal, the usage record including the usage time within a first preset duration; and determine the average daily usage time of the target terminal, a first time period, and a second time period based on the usage record of the target terminal, wherein the first time period is the time period with the highest daily usage frequency of the target terminal, and the second time period is the time period with the lowest daily usage frequency of the target terminal.

[0100] If the target terminal is currently in use during the first time period, the estimated remaining usage time of the target terminal is determined based on the target terminal's average daily usage time and the target terminal's current usage time.

[0101] If the target terminal is currently in the second time period, the estimated usage time of the target terminal is determined based on the average daily usage time of the target terminal and the first ratio, where the first ratio is the ratio of the second time period to the day. The estimated remaining usage time of the target terminal is determined based on the estimated usage time of the target terminal and the current usage time of the target terminal.

[0102] If the target terminal is not currently in the first or second time period, the estimated usage time of the target terminal is determined based on the average daily usage time of the target terminal and the first ratio. The second ratio is the ratio of the time period other than the first and second time periods in a day to the total time of a day. The estimated remaining usage time of the target terminal is determined based on the estimated usage time of the target terminal and the current usage time of the target terminal.

[0103] If the estimated remaining usage time of the target terminal is less than the second preset time, then the target terminal will be attached.

[0104] In one feasible embodiment, the signaling processing device 50 based on the attracted terminal further includes: if the first response information is NACK information, determining the movement status information of the target terminal based on the Manhattan distance of the target terminal, the movement status information including movement speed and movement direction; and sending third information to the soldier's master station control terminal, the third information carrying the movement status information of the target terminal.
