[0051] In this embodiment, a method for locating a terminal device is provided, which is applied to the above-mentioned computer terminal. FIG2 is a flow chart of a method for locating a terminal device according to an embodiment of the present application. As shown in FIG2 , the flow chart includes the following steps:

[0052] Step S202: detecting the current connection status of a detection base station, wherein the communication range of the detection base station covers N detection areas where the terminal device is prohibited from use, where N is a positive integer greater than or equal to 2;

[0053] Step S204: When the connection state indicates that a target terminal device is currently connected to the detection base station, a target advance parameter corresponding to the target terminal device is obtained, wherein each detection area is covered by a distributed remote end of the detection base station, the detection base station includes N distributed remote ends, each of the N distributed remote ends is assigned a different advance parameter, and the terminal device in each detection area establishes communication with the detection base station through the corresponding distributed remote end, and the advance parameter is used to indicate the amount of time in advance that a signal sent by the terminal device under the corresponding distributed remote end needs to be sent;

[0054] Step S206, finding the target distribution far end corresponding to the target lead parameter from the lead parameters and distribution far ends that have corresponding relationships;

[0055] Step S208: Determine the detection area where the target distribution remote end is located as the target detection area, wherein the target detection area is the location where the target terminal device is located.

[0056] Through the above steps, the current connection status of the detection base station is detected, wherein the communication range of the detection base station covers N detection areas where the terminal device is prohibited from being used, N being a positive integer greater than or equal to 2; when the connection status is used to indicate that there is currently a target terminal device connected to the detection base station, a target advance parameter corresponding to the target terminal device is obtained, wherein each detection area is covered by a distributed remote end of the detection base station, the detection base station includes N distributed remote ends, each of the N distributed remote ends is assigned a different advance parameter, and the terminal device in each detection area establishes communication with the detection base station through the corresponding distributed remote end, the advance parameter is used to indicate the amount of time in advance that a signal sent by the terminal device under the corresponding distributed remote end needs to be sent, and the amount of time in advance is used to correct the signal transmission delay of the signal; the target distributed remote end corresponding to the target advance parameter is found from the advance parameters and distributed remote ends that have a corresponding relationship; The detection area where the target distribution remote end is located is determined as the target detection area, wherein the target detection area is the location of the target terminal device. That is, different advance parameters are pre-assigned to the remote ends of the detection areas of N prohibited terminal devices covered by the detection base station. When a target terminal device is currently connected to the detection base station, the target advance parameter corresponding to the target terminal device is directly obtained, and the target distribution remote end corresponding to the target advance parameter is found from the advance parameters and the distribution remote end with a corresponding relationship. Then, the detection area where the target distribution remote end is located is determined as the target detection area, that is, the location of the target terminal device. Through the above method, for any terminal device connected to the detection base station in the detection area, the detection area to which the terminal device belongs can be directly reversely located based on the target advance parameter of the terminal device, greatly simplifying the terminal device positioning method and improving the terminal device positioning efficiency. The above technical solution solves the problem of high complexity of terminal device positioning in related technologies and achieves the technical effect of improving the complexity of terminal device positioning.

[0057] In the technical solution provided in step S202 above, taking N as 4 as an example, FIG3 is a schematic diagram of a positioning scenario of a terminal device according to an embodiment of the present application. As shown in FIG3 , the communication range of the detection base station covers detection area 1 to detection area 4 where the use of terminal devices is prohibited. The base station type of the detection base station is not limited, and the terminal device may include, but is not limited to, a mobile phone, a computer, or other device with communication functions. The current connection status of the detection base station may indicate whether the current detection base station is connected to a terminal device;

[0058] In the technical solution provided in the above step S204, as shown in Figure 3, when the connection state is used to indicate that there is currently a target terminal device (for example, a mobile phone) connected to the detection base station, the target advance parameter (for example, 4) corresponding to the target terminal device is obtained, wherein each detection area is covered by a distributed remote end of the detection base station, and the detection base station includes 4 distributed remote ends (distributed remote end 1, distributed remote end 2, distributed remote end 3, distributed remote end 4), and each of the 4 distributed remote ends is assigned a different advance parameter (for example, distributed remote end 1 is assigned an advance parameter "2", distributed remote end 2 is assigned an advance parameter "4", etc.), and the terminal device in each detection area establishes communication with the detection base station through the corresponding distributed remote end, and the advance parameter is used to indicate the amount of time in advance that the signal sent by the terminal device under the corresponding distributed remote end needs to be sent.

[0059] Optionally, in this embodiment, when a mobile phone (terminal device) is connected to a base station (detection base station), a built-in advance parameter (also known as a timing advance parameter) refers to the time advance that the mobile phone will set before sending a signal in order to accurately synchronize the communication clock when communicating with the base station. The purpose of this timing advance parameter is to correct the delay during signal transmission to ensure that communication between the mobile phone and the base station can be carried out within the correct time window. The delay in communication mainly includes the following aspects:

[0060] 1) Signal transmission delay: The speed at which signals propagate in the air is limited, so there will be a certain time delay between the signal being sent from the mobile phone and being received by the base station.

[0061] 2) Signal processing delay: Before sending a signal, the mobile phone needs to perform a series of signal processing operations, such as modulation, encoding, encryption, etc. These operations take a certain amount of time.

[0062] 3) Network transmission delay: There will be a certain amount of network transmission delay during the signal transmission from the base station to the core network and then back to the target mobile phone.

[0063] To address the latency issues mentioned above, the phone will pre-send its signal a certain amount of time. Typically, this amount of time is calculated based on the distance between the phone and the base station and the speed of signal propagation. However, in this application, the pre-sentence parameter is pre-set (because the latency from the remote end to the phone is minimal due to the close distance).

[0064] In an exemplary embodiment, before obtaining the target advance parameter corresponding to the target terminal device, the following methods may be included but are not limited to: obtaining the minimum signal transmission delay of signal transmission between the terminal devices in the N distributed remote ends and the detection base station; identifying the target mobile communication standard currently used by the detection base station; and allocating different advance parameters to each of the N distributed remote ends according to the target mobile communication standard and the minimum signal transmission delay.

[0065] Optionally, in this embodiment, the target mobile communication standard currently used by the detection base station is identified, wherein the target mobile communication standard includes GSM (Global System for Mobile Communications, Global System for Mobile Communications, second generation (2G) mobile communication technology standard), LTE (Long-Term Evolution, fourth generation (4G) mobile communication technology standard), NR (New Radio, fifth generation (5G) mobile communication technology standard).

[0066] Optionally, in this embodiment, the minimum signal transmission delay between the terminal devices in the N distributed remote ends and the detection base station is obtained. As shown in Figure 3, the signal transmission delay of the distributed remote end 1 is the smallest, and the allocated advance parameter is 2.

[0067] In an exemplary embodiment, different advance parameters may be allocated to each of the N distributed remote ends according to the target mobile communication standard and the minimum signal transmission delay in the following manner, but is not limited to: generating an advance parameter sequence according to the target mobile communication standard and the minimum signal transmission delay, wherein the advance parameter sequence includes N advance parameters that increase in sequence, and the difference between the i-th advance parameter and the (i-1)-th advance parameter in the advance parameter sequence is greater than a preset threshold, where i is a positive integer greater than or equal to 2 and less than or equal to N; and allocating different advance parameters to each distributed remote end according to the advance parameter sequence.

[0068] Optionally, in this embodiment, the lead parameter sequence can be, but is not limited to, an arithmetic progression. The difference between the i-th lead parameter and the (i-1)-th lead parameter in the lead parameter sequence is greater than a preset threshold. This configuration allows for distinct differences in the lead parameters assigned to different distributed remote locations, thereby enabling more accurate inference of the detection area of ​​the terminal device based on the lead parameters. As shown in Figure 3, the lead parameter sequence is 2, 4, 6, and 8, with the difference between the two entries being 2.

[0069] In an exemplary embodiment, an advance parameter sequence can be generated according to the target mobile communication standard and the minimum signal transmission delay in the following manner, but is not limited to: generating an initial advance parameter according to the target mobile communication standard and the minimum signal transmission delay, wherein the initial advance parameter is the advance parameter required to be adopted by the detecting base station and terminal device under the target mobile communication standard in order to correct the minimum signal transmission delay; using the initial advance parameter as the first advance parameter of the advance parameter sequence, and using a target value greater than the preset threshold as the difference between the i-th advance parameter and the (i-1)-th advance parameter to generate N-1 advance parameters, thereby obtaining the advance parameter sequence.

[0070] Optionally, in this embodiment, an initial advance parameter is generated based on the target mobile communication standard and the minimum signal transmission delay. Because the time steps corresponding to different mobile communication standards are different, the same minimum signal transmission delay has different corresponding initial advance parameters under different mobile communication standards. For example, the minimum signal transmission delay is 10 microseconds. When the target mobile communication standard is GSM, the corresponding initial advance parameter is 2; when the target mobile communication standard is NR, the corresponding initial advance parameter is 19.

[0071] Optionally, in this embodiment, the generated initial lead parameter is used as the first lead parameter in the lead parameter sequence, and a target value greater than the preset threshold is used as the difference between the i-th lead parameter and the (i-1)-th lead parameter to generate N-1 lead parameters. For example, if the initial lead parameter is 2 and the target value is 2, then the second lead parameter in the lead parameter sequence is 4, the third lead parameter is 6, and the fourth lead parameter is 8. Currently, the lead parameter sequence exemplified here is an arithmetic progression, and the difference between the previous and next terms may not be a constant. For example, the lead parameter sequence is: 2, 5, 7, 9.

[0072] In an exemplary embodiment, different advance parameters may be assigned to each of the distributed remote ends according to the advance parameter sequence in the following manner, but not limited to: sorting the N distributed remote ends according to the signal transmission delay of each of the distributed remote ends to obtain a distributed remote end sequence, wherein the signal transmission delay of the (i-1)th distributed remote end in the distributed remote end sequence is less than or equal to the signal transmission delay of the i-th distributed remote end; and determining the i-th advance parameter in the advance parameter sequence as the advance parameter of the i-th distributed remote end in the distributed remote end sequence.

[0073] Optionally, in this embodiment, the N distributed remote ends are sorted according to the signal transmission delay of each distributed remote end to obtain a distributed remote end sequence. FIG4 is a schematic diagram of allocating advance parameters to distributed remote ends according to an embodiment of the present application. As shown in FIG4 , the signal transmission delay of distributed remote end 1 is the smallest, followed by distributed remote end 2, distributed remote end 3, and distributed remote end 4, with distributed remote end 4 having the largest signal transmission delay. If the advance parameter sequence is 2, 4, 6, and 8, then the i-th advance parameter in the advance parameter sequence is determined as the advance parameter of the i-th distributed remote end in the distributed remote end sequence, i.e., the advance parameter of distributed remote end 1 is 2, the advance parameter of distributed remote end 2 is 4, the advance parameter of distributed remote end 3 is 6, and the advance parameter of distributed remote end 4 is 8.

[0074] Optionally, in this embodiment, the signal transmission delay at the remote end is related to the length of the optical fiber between the remote end and the detection base station. The shorter the optical fiber length, the smaller the signal transmission delay.

[0075] In an exemplary embodiment, after allocating different advance parameters to each of the N distributed remote ends according to the target mobile communication standard and the minimum signal transmission delay, it can be but is not limited to also include the following method: before the terminal device in the reference distributed remote end communicates with the detection base station, the signal transmission delay between the reference distributed remote end and the detection base station is adjusted to match the advance parameter of the reference distributed remote end, wherein the reference distributed remote end is any one of the N distributed remote ends; during the process of communication between the terminal device in the reference distributed remote end and the detection base station, the signal is transmitted according to the signal transmission delay matching the advance parameter of the reference distributed remote end.

[0076] Optionally, in this embodiment, in the related art, the advance parameter is generated based on the signal transmission delay, while in this application the advance parameter is pre-set and allocated. Since the advance parameter and the signal transmission delay are in a matching relationship with each other, after allocating the advance parameter, the corresponding signal transmission delay needs to be synchronously adjusted to match the allocated advance parameter.

[0077] In an exemplary embodiment, the signal transmission delay between the remote end of the reference distribution and the detection base station can be adjusted to match the advance parameter of the remote end of the reference distribution in the following manner, but is not limited to: adjusting the digital processing delay and the optical fiber transmission delay between the remote end of the reference distribution and the detection base station to match the advance parameter of the remote end of the reference distribution, wherein the digital processing delay is the time delay caused by the digital processing of the signal during the communication between the terminal device in the remote end of the reference distribution and the detection base station, and the optical fiber transmission delay is the time delay caused by the transmission of the signal in the optical fiber during the communication between the terminal device in the remote end of the reference distribution and the detection base station.

[0078] Optionally, in this embodiment, Figure 5 is a schematic diagram of an adjustment based on signal transmission delay according to an embodiment of the present application. As shown in Figure 5, the signal transmission delay between the remote end of the reference distribution and the detection base station includes a digital processing delay and an optical fiber transmission delay. By adjusting the digital processing delay and the optical fiber transmission delay, the signal transmission delay between the remote end of the reference distribution and the detection base station is matched with the pre-allocated advance parameters.

[0079] In the technical solution provided in step S206 above, there is a correspondence between the lead parameters and the distribution distal ends. As shown in FIG3 , distribution distal end 1 corresponds to lead parameter 2, distribution distal end 2 corresponds to lead parameter 4, distribution distal end 3 corresponds to lead parameter 6, and distribution distal end 4 corresponds to lead parameter 8. Given that the target lead parameter is 4, the corresponding target distribution distal end can be inferred to be distribution distal end 2.

[0080] In the technical solution provided in step S208 above, after determining the target distribution remote end corresponding to the target terminal device, the detection area where the target distribution remote end is located can be determined as the target detection area, that is, the location of the target terminal device. As shown in Figure 3, after determining that the target distribution remote end corresponding to the target terminal device is distribution remote end 2, the detection area where distribution remote end 2 is located is determined as the target detection area, that is, detection area 2, to achieve positioning of the target terminal device. After obtaining the positioning address of the target terminal device, the detected mobile phone related information (such as telephone number, etc.) is associated with the positioning address and sent to the positioning account. The positioning account is used to monitor whether there is a terminal device connected to the detection base station. The positioning address can be sent periodically and updated in real time.

[0081] This application proposes a terminal device positioning method that can be applied to a digital optical distribution system. This system transmits digitized radio frequency signals from the near-end (downlink) to the far-end (uplink) via optical fiber. This system incurs both digital processing delay and optical fiber transmission delay. Adding a buffer during transmission increases signal transmission delay (the delay is proportional to the buffer size). Furthermore, the system also amplifies the signal to compensate for spatial radio frequency signal loss from the far-end to the terminal device. The buffer size can be adjusted to achieve the signal transmission delay corresponding to a preset lead parameter.
