In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a detection base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0049] In this embodiment, a terminal device positioning method is provided, which is applied to the above-mentioned computer terminal. Figure 2 is a flow chart of a method for positioning a terminal device according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0050] Step S202, detecting the current connection state of the detection base station, wherein the communication range of the detection base station covers N detection areas where the terminal device is prohibited from being used, where N is a positive integer greater than or equal to 2;

[0051] Step S204, in a case where the connection state 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 of the detection areas 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;

[0052] Step S206, searching for the target distribution far end corresponding to the target advance parameter from the advance parameters and distribution far ends having a corresponding relationship;

[0053] 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.

[0054] Through the above steps, the current connection state of the detection base station is detected, wherein the communication range of the detection base station covers N detection areas where the terminal equipment is prohibited, and N is a positive integer greater than or equal to 2; when the connection state is used to indicate that there is currently a target terminal equipment connected to the detection base station, the target advance parameter corresponding to the target terminal equipment 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 equipment 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 that the signal sent by the terminal equipment under the corresponding distributed remote end needs to be sent in advance, and the amount of time sent 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 parameter and the distributed remote end having 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 distribution remote ends of the N detection areas covered by the detection base station where the terminal devices are prohibited from being used. When there is currently a target terminal device 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 parameter and the distribution remote end with a corresponding relationship, and 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, which greatly simplifies the terminal device positioning method and improves the terminal device positioning efficiency. The above technical solution solves the problem that the positioning complexity of the terminal device is high in the related technology, and achieves the technical effect of improving the positioning complexity of the terminal device.

[0055] In the technical solution provided in the above step S202, taking N as 4 as an example, Figure 3 is a schematic diagram of a positioning scenario of a terminal device according to an embodiment of the present application, such as Figure 3 As shown, the communication range of the detection base station covers detection area 1 to detection area 4 where the use of terminal devices is prohibited, wherein the base station type of the detection base station is not limited, and the terminal device can include but is not limited to mobile phones, computers and other devices with communication functions. The current connection status of the detection base station can indicate whether the current detection base station is connected to a terminal device;

[0056] In the technical solution provided in the above step S204, if Figure 3As shown, 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.

[0057] Optionally, in this embodiment, when the mobile phone (terminal device) is connected to the base station (detection base station), the built-in advance parameter (also called time advance parameter) means that when the mobile phone communicates with the base station, in order to accurately synchronize the communication clock, the mobile phone will advance a certain amount of time before sending the signal. The role of this time advance parameter is to correct the delay in the signal transmission process to ensure that the 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:

[0058] 1) Signal transmission delay: The speed at which signals propagate in the air is limited, so there will be a certain time delay from the time the signal is sent from the mobile phone to the time it is received by the base station.

[0059] 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.

[0060] 3) Network transmission delay: The signal is transmitted from the base station to the core network and then returned to the target mobile phone. There will be a certain network transmission delay in this process.

[0061] In order to solve the problem caused by the above delay, the mobile phone will advance a certain amount of time before sending the signal. Usually, this amount of time is calculated based on the distance between the mobile phone and the base station and the signal propagation speed. However, in this application, the advance amount parameter is pre-set and allocated (because the delay from the remote end of the distribution to the mobile phone is very small due to the close distance).

[0062] 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 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.

[0063] 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 mobile communication system, 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).

[0064] Optionally, in this embodiment, the minimum signal transmission delay between the N distributed remote terminal devices and the detection base station is obtained, such as Figure 3 As shown, the signal transmission delay of the distribution remote end 1 is the smallest, and the allocated advance parameter is 2.

[0065] 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: an advance parameter sequence is generated 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, and i is a positive integer greater than or equal to 2 and less than or equal to N; and different advance parameters are allocated to each distributed remote end according to the advance parameter sequence.

[0066] Optionally, in this embodiment, the lead parameter sequence can be, but is not limited to, an arithmetic progression, and 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 value. This setting can make the lead parameters of different distributed remote allocations form obvious differences, thereby making the subsequent detection area of ​​the terminal device described in reverse inference based on the lead parameter more accurate. Figure 3 As shown, the advance parameter series is: 2, 4, 6, 8, and the difference between the two terms in the series is 2.

[0067] 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 detected base station and terminal device in order to correct the minimum signal transmission delay under the target mobile communication standard; 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.

[0068] Optionally, in this embodiment, an initial advance parameter is generated according to the target mobile communication standard and the minimum signal transmission delay. Because different mobile communication standards correspond to different time steps, 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; and when the target mobile communication standard is NR, the corresponding initial advance parameter is 19.

[0069] Optionally, in this embodiment, the generated initial lead parameter is used as the first lead parameter of the lead parameter sequence, and the 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 items may not be a constant, for example, the lead parameter sequence is: 2, 5, 7, 9.

[0070] 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 ith distributed remote end; and determining the ith advance parameter in the advance parameter sequence as the advance parameter of the ith distributed remote end in the distributed remote end sequence.

[0071] Optionally, in this embodiment, the N distributed remote ends are sorted according to the signal transmission delay of each of the distributed remote ends to obtain a distributed remote end sequence, Figure 4 is a schematic diagram of distributing remote allocation advance parameters according to an embodiment of the present application, such as Figure 4 As shown, 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, wherein the signal transmission delay of distributed remote end 4 is the largest. If the advance parameter sequence is: 2, 4, 6, 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, that is, 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.

[0072] Optionally, in this embodiment, the signal transmission delay at the remote distribution end is related to the optical fiber length between the remote distribution end and the detection base station. The shorter the optical fiber length, the smaller the signal transmission delay.

[0073] 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 include but is not limited to the following manner: 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 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.

[0074] Optionally, in this embodiment, in the related art, the advance parameter is generated based on the signal transmission delay, while in the present application the advance parameter is pre-set and allocated. Since the advance parameter and the signal transmission delay are in a mutually matching relationship, after allocating the advance parameter, the corresponding signal transmission delay needs to be synchronously adjusted to match the allocated advance parameter.

[0075] 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.

[0076] Optionally, in this embodiment, Figure 5 is a schematic diagram of adjusting according to signal transmission delay according to an embodiment of the present application, such as Figure 5 As shown, 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 parameter.

[0077] In the technical solution provided in the above step S206, there is a corresponding relationship between the advance parameter and the remote end of the distribution, such as Figure 3 As shown, the distribution distal end 1 corresponds to the advance parameter 2, the distribution distal end 2 corresponds to the advance parameter 4, the distribution distal end 3 corresponds to the advance parameter 6, and the distribution distal end 4 corresponds to the advance parameter 8. Given that the target advance parameter is 4, the corresponding target distribution distal end can be inferred to be: distribution distal end 2.

[0078] In the technical solution provided in the above step S208, 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 where the target terminal device is located, such as Figure 3 As shown, 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 the 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.

[0079] The terminal device positioning method proposed in this application can be applied to the digital optical distribution system, which transmits the digitized radio frequency signal from the near end of the distribution (downlink) to the far end of the distribution (uplink and vice versa) through optical fiber. The digital optical distribution system will have digital processing delay and optical fiber transmission delay; adding a buffer in the transmission process can increase the signal transmission delay (the delay is proportional to the buffer size). Of course, the digital optical distribution system also has the function of amplifying the signal to compensate for the loss of the spatial radio frequency signal output from the far end of the distribution to the terminal device. The buffer size can be adjusted to achieve the signal transmission delay corresponding to the preset advance parameter.
