By adopting the technical scheme, the problems of high complexity of positioning of the terminal equipment and the like in the related technology are solved, and the technical effect of improving the complexity of positioning of the terminal equipment is realized.
In the technical solution provided in step S202, taking the value of N4 as an example, fig. 3 is a schematic diagram of a positioning scenario of a terminal device according to an embodiment of the present application, as shown in fig. 3, a communication range of a detection base station covers a detection area 1 to a detection area 4 where use of the terminal device is prohibited, where a base station type of the detection base station is not limited, and the terminal device may include, but is not limited to, devices with communication functions such as a mobile phone and a computer. The current connection state of the detection base station can indicate whether the current detection base station is connected with terminal equipment or not;
in the solution provided in step S204, as shown in fig. 3, in a case where the connection status is used to indicate that a target terminal device (for example, a mobile phone) is currently connected to a detection base station, a target advance parameter (for example, 4) corresponding to the target terminal device is obtained, where each detection area is covered by one distribution far end of the detection base station, the detection base station includes 4 distribution far ends (distribution far end 1, distribution far end 2, distribution far end 3, distribution far end 4), each of the 4 distribution far ends is allocated with a different advance parameter (for example, distribution far end 1 is allocated with an advance parameter "2", distribution far end 2 is allocated with an advance parameter "4", etc.), and the terminal device in each detection area establishes communication with the detection base station through the corresponding distribution far end, where the advance parameter is used to indicate an amount of time that a signal sent by the terminal device under the corresponding distribution far end needs to be sent in advance.
Optionally, in this embodiment, when the mobile phone (terminal device) is connected to the base station (detecting base station), the own advance parameter (also called as time advance parameter) refers to that the mobile phone advances a certain amount of time before sending a signal in order to accurately synchronize the communication clock when the mobile phone communicates with the base station. The function of this time advance parameter is to correct the delay in the signal transmission process to ensure that the communication between the handset and the base station can take place within the correct time window. The latency in communication mainly includes the following aspects:
1) Signal transmission delay: the speed at which the signal propagates in air is limited, so there is some time delay from the transmission of the signal from the handset to the reception of the signal at the base station.
2) Signal processing time delay: the handset needs to perform a series of signal processing operations, such as modulation, coding, encryption, etc., before transmitting the signal, which all require a certain time.
3) Network transmission delay: the signal is transmitted from the base station to the core network and then returned to the target mobile phone, and a certain network transmission delay exists in the process.
To address the problems with the time delays described above, the mobile phone may advance by a certain amount of time before transmitting the signal. Typically, this amount of time is calculated based on the distance between the handset and the base station and the signal propagation speed. In the present application, however, the advance parameter is preset for allocation (because the delay from the far end of the distribution to the mobile phone is less affected by the close distance).
In an exemplary embodiment, before the obtaining the target advance parameter corresponding to the target terminal device, the method may, but is not limited to, further include the following ways: acquiring the minimum signal transmission delay of signal transmission between the terminal equipment in the N distributed far ends and the detection base station; identifying a target mobile communication standard currently used by the detection base station; and distributing different advance parameters to each of N distribution remote ends according to the target mobile communication standard and the minimum signal transmission delay.
Optionally, in this embodiment, the target mobile communication standard currently used by the detecting base station is identified, where 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).
Optionally, in this embodiment, the minimum signal transmission delay of signal transmission between the terminal devices in the N distributed remote ends and the detecting base station is obtained, as shown in fig. 3, the signal transmission delay of the distributed remote end 1 is minimum, and the allocated advance parameter is 2.
In one exemplary embodiment, each of the N distributed remote ends may be assigned a different one of the advance parameters according to the target mobile communication standard and the minimum signal transmission delay by, but not limited to: generating an advance parameter array according to the target mobile communication standard and the minimum signal transmission delay, wherein the advance parameter array comprises N advance parameters which are sequentially increased, the difference between the i-th advance parameter and the (i-1) -th advance parameter in the advance parameter array is larger than a preset threshold, i is a positive integer which is larger than or equal to 2 and smaller than or equal to N; and distributing different advance parameters to each distribution far end according to the advance parameter array.
Optionally, in this embodiment, the advance parameter array may be, but not limited to, an arithmetic progression, where the difference between the i-th advance parameter and the (i-1) -th advance parameter in the advance parameter array is greater than a preset threshold, so that the advance parameters distributed remotely in different distributions can be obviously differentiated, and further, the detection area of the terminal device is further accurately reversely pushed according to the advance parameters. As shown in fig. 3, the advance parameter number is listed as: 2. 4, 6, 8, the difference between the two items of the series is 2.
In one exemplary embodiment, the advance parameter array may be generated according to the target mobile communication standard and the minimum signal transmission delay by, but not limited to, the following: 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 detection base station and the terminal equipment for correcting the minimum signal transmission delay under the target mobile communication standard; and taking the initial lead parameter as a 1 st lead parameter of the lead parameter array, taking a target value larger than the preset threshold value as a difference value between the i-th lead parameter and the (i-1) -th lead parameter to generate an N-1-th lead parameter, and obtaining the lead parameter array.
Optionally, in this embodiment, the initial lead parameter is generated according to 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 is different, the initial lead parameters corresponding to different mobile communication standards are also different, for example, the minimum signal transmission delay is 10 microseconds, and when the target mobile communication standard is GSM, the corresponding initial lead parameter is 2; and when the target mobile communication standard is NR, the corresponding initial lead parameter is 19.
Optionally, in this embodiment, the generated initial lead parameter is used as the 1 st lead parameter of the lead parameter array, and the target value larger than the preset threshold is used as the difference between the i-th lead parameter and the (i-1) -th lead parameter to generate the N-1 th lead parameter, for example, the initial lead parameter is 2, the target value is 2, and the 2 nd lead parameter is 4, the 3 rd lead parameter is 6, and the 4 th lead parameter is 8 in the lead parameter array. Currently, the advance parameter sequence exemplified here is an arithmetic progression, and furthermore, the difference between the preceding term and the following term may not be a constant value, for example, the advance parameter sequence is: 2. 5, 7 and 9.
In one exemplary embodiment, each of the distributed remote ends may be assigned a different one of the advance parameters according to the advance parameter array by, but not limited to: sequencing N distribution remote ends according to the signal transmission time delay of each distribution remote end to obtain a distribution remote end sequence, wherein the signal transmission time delay of the (i-1) th distribution remote end in the distribution remote end sequence is smaller than or equal to the signal transmission time delay of the i-th distribution remote end; and determining the ith advance parameter in the advance parameter array as the advance parameter of the ith distribution far end in the distribution far end sequence.
Optionally, in this embodiment, the N distribution distal ends are ordered according to the signal transmission delay of each distribution distal end to obtain a distribution distal end sequence, fig. 4 is a schematic diagram of distribution distal end distribution advance parameters according to an embodiment of the present application, as shown in fig. 4, a signal transmission delay of a distribution distal end 1 is minimum, and then the distribution distal ends are distributed distal end 2, 3, and 4 in sequence, where the signal transmission delay of the distribution distal end 4 is maximum. If the advance parameter number is: 2. 4, 6, 8, then determining the i-th advance parameter in the advance parameter array as the i-th advance parameter of the distribution far-end in the distribution far-end sequence, namely, the advance parameter of the distribution far-end 1 is 2, the advance parameter of the distribution far-end 2 is 4, the advance parameter of the distribution far-end 3 is 6, and the advance parameter of the distribution far-end 4 is 8.
Optionally, in this embodiment, the signal transmission delay of the distributed remote end is related to the optical fiber length of the distributed remote end and the detecting base station time, and the shorter the optical fiber length, the smaller the signal transmission delay.
In an exemplary embodiment, after the allocating of the different advance parameter for each of the N distribution remotes according to the target mobile communication standard and the minimum signal transmission delay, the method may, but is not limited to, further include adjusting the signal transmission delay between a reference distribution remote and a detection base station to match the advance parameter of the reference distribution remote before a terminal device in the reference distribution remote communicates with the detection base station, wherein the reference distribution remote is any one of the N distribution remotes; and in the process of communicating the terminal equipment in the reference distribution far end with the detection base station, transmitting signals according to signal transmission delay matched with the advance parameter of the reference distribution far end.
Optionally, in this embodiment, in the related art, the advance parameter is generated according to the signal transmission delay, and in the present application, the advance parameter is preset and allocated, and because the advance parameter and the signal transmission delay are in a mutually matched relationship, after the advance parameter is allocated, the corresponding signal transmission delay needs to be synchronously adjusted to match with the allocated advance parameter.
In one exemplary embodiment, the signal transmission delay between the reference profile remote and the detecting base station may be adjusted to match the advance parameter of the reference profile remote, but is not limited to, by: and adjusting digital processing time delay and optical fiber transmission time delay between the reference distribution far end and the detection base station to be matched with the advance parameter of the reference distribution far end, wherein the digital processing time delay is time delay brought by digital processing of signals in the process of communication between terminal equipment in the reference distribution far end and the detection base station, and the optical fiber transmission time delay is time delay brought by transmission of signals in an optical fiber in the process of communication between the terminal equipment in the reference distribution far end and the detection base station.
Optionally, in this embodiment, fig. 5 is a schematic diagram of signal transmission delay adjustment according to an embodiment of the present application, as shown in fig. 5, the signal transmission delay between the reference distribution remote end and the detection base station includes a digital processing delay and an optical fiber transmission delay, and by adjusting the digital processing delay and the optical fiber transmission delay, the signal transmission delay between the reference distribution remote end and the detection base station is matched with a pre-allocated advance parameter.
