[0028] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In order to describe the present application in more detail, the positioning correction method, device, storage medium and equipment provided by the present application will be described in detail in the following with reference to the drawings.

[0029] The IP address positioning library stores a large number of IP addresses, each IP address corresponds to a physical address in reality, which is convenient for user query. For example, in the case that the user knows a certain IP address, the specific positioning of the IP address can be found. Although the IP address has a corresponding physical address, there is no necessary connection between them, and the operator can adjust the actual physical address corresponding to the IP address according to the demand, so the physical address corresponding to the IP address is dynamically changed, and there is no completely accurate IP address positioning library. There are multiple IP address positioning libraries on the market at present, but there is no optimal IP address positioning library. In the process of positioning using IP address, it is impossible to determine which IP address positioning library data is accurate, resulting in that the accurate physical address corresponding to the IP address cannot be obtained.

[0030] The present application provides a specific application scenario of the positioning correction method. The application scenario includes a terminal device provided by the embodiments, which includes but is not limited to a smart phone and a computer device, wherein the computer device can be at least one of a desktop computer, a portable computer, a laptop computer, a tablet computer and the like. The user operates the terminal device, and the terminal device executes the positioning correction method of the present application, combined with theFigure 1 For details, please refer to the method embodiment of the positioning correction.

[0031] Step S101: Obtain the first IP segment and the first positioning information of the first IP address positioning library, and the second IP segment and the second positioning information of the second IP address positioning library.

[0032] The first IP address positioning library is an offline stored IP address positioning library of the embodiment, which stores a plurality of IP addresses or IP address segments, and is generally a whois IP library. The whois IP library is a database for querying the registration state and registration information of a domain name. Through whois query, it can be known whether the target domain name is registered, who the domain name owner is, and the address of the domain name registrar. According to the information obtained by the above query, the positioning information corresponding to the IP address or the IP address segment can be obtained, that is, the first positioning information in the embodiment.

[0033] The second IP address positioning library is an IP address positioning library with high accuracy, which also stores a plurality of IP addresses or IP address segments, and is used for comparison with the first IP address positioning library to correct the specific positioning information of the first IP address positioning library. In the embodiment, the IP2region library is selected as the second IP address positioning library. The IP2region library is an offline IP address positioning library with an accuracy of 99.9%, which can achieve a query speed of 0.0x milliseconds. The corresponding positioning information obtained by querying the IP2region library is the second positioning information in the embodiment.

[0034] Step S102: If the first IP segment and the second IP segment have an intersection, and the first positioning information and the second positioning information are not the same, the IP start address and the IP end address corresponding to the first positioning information and the second positioning information are intercepted.

[0035] Specifically, the IP addresses between the first IP segment and the second IP segment are compared one by one. In the comparison process, the specific IP addresses are converted into numbers according to a preset rule, and the size of each IP address is compared to determine whether the first IP segment and the second IP segment have an intersection. The first IP segment and the second IP segment have an intersection include the following three cases:

[0036] (1) The first IP segment and the second IP segment have a partial overlap, specifically: the IP start address of the first IP segment is less than the start address of the second IP segment, and the end address of the first IP segment is greater than the end address of the second IP segment; or the IP start address of the second IP segment is less than the start address of the first IP segment, and the end address of the second IP segment is greater than the end address of the second IP segment;

[0037] (2) The first IP segment and the second IP segment completely overlap, specifically, the start address of the first IP segment is equal to the start address of the second IP segment, and the end address of the first IP segment is equal to the end address of the second IP segment.

[0038] (3) The first IP segment and the second IP segment only have the start address or the end address overlapping, specifically, the end address of the first IP segment is equal to the start address of the second IP segment, or the end address of the second IP segment is equal to the start address of the first IP segment.

[0039] On the basis of the comparison of the first IP segment and the second IP segment to determine whether there is an intersection between the two, further comparison is made on whether the first positioning information corresponding to the first IP segment and the second positioning information corresponding to the second IP segment are the same. If the positioning information corresponding to the two IP address segments with the intersection is not the same, it indicates that the first IP address positioning library may have information errors, and the positioning information corresponding to the IP segment needs to be corrected.

[0040] Therefore, in the case that the first positioning information and the second positioning information are not the same, the IP start address and the IP end address corresponding to the first positioning information and the second positioning information are intercepted. At this time, the IP segment to be intercepted should be the IP segment with the intersection between the first IP segment and the second IP segment, the IP start address to be intercepted is the start address of the IP segment with the intersection, and the IP end address to be intercepted is the end address of the IP segment with the intersection.

[0041] Step S103: In the third IP address positioning library, the third positioning information is obtained according to the IP start address and the IP end address.

[0042] Since the first IP address positioning library and the second IP address positioning library obtain different positioning information for the same IP segment, in order to improve the accuracy, a third IP address positioning library is introduced to correct the positioning information of the IP segment. Since the third IP address positioning library is introduced for correction, only the third positioning information between the aforementioned IP start address and IP end address needs to be intercepted. In the embodiment of the present application, the third IP address positioning library can be selected from IP address libraries with higher accuracy, such as Baidu IP library, Gaode IP library or Chunqing IP library, etc.

[0043] Step S104: The first positioning information, the second positioning information and the third positioning information are compared.

[0044] Step S105: If the first positioning information and the third positioning information are the same, the first positioning information is recorded as the standard positioning information of the IP segment between the IP start address and the IP end address.

[0045] In the embodiment, the first positioning information of the whois IP library is the same as the third positioning information of the Baidu IP library, which can be seen from the table.Figure 2 .

[0046] Step S106: If the second positioning information is the same as the third positioning information, the second positioning information is recorded as the standard positioning information of the IP segment between the IP start address and the IP end address.

[0047] In the embodiment, the second positioning information of the IP2region library is the same as the third positioning information of the Baidu IP library, which can be seen from the attached Figure 3 .

[0048] According to the principle of minority following majority, after the third IP address positioning library is referenced, for the same IP segment, if the positioning information of which IP address positioning library is the same as the third positioning information, the positioning information of the IP address positioning library is taken as the standard positioning information of the IP segment.

[0049] Step S107: The first positioning information of the first IP address positioning library is updated according to the standard positioning information.

[0050] Further, if the first positioning information, the second positioning information and the third positioning information are all different, the second positioning information is recorded as the standard positioning information of the IP segment between the IP start address and the IP end address.

[0051] In the case that the positioning information of the plurality of IP address positioning libraries is inconsistent, the positioning information of the IP address positioning library with the highest accuracy (the second IP address positioning library in the embodiment, i.e. the IP2region library) is selected as the standard positioning information.

[0052] Further, when comparing the first positioning information, the second positioning information and the third positioning information, since the accuracy of each IP address positioning library is different, the above three positioning information needs to be set at the same positioning level for comparison, which specifically includes:

[0053] Step S201: If the city in the first positioning information, the second positioning information and the third positioning information is not empty, compare whether the city in the first positioning information, the second positioning information and the third positioning information is the same.

[0054] Step S202: If the city in the first positioning information, the second positioning information or the third positioning information is empty, compare whether the province in the first positioning information, the second positioning information and the third positioning information is the same.

[0055] In addition, for the positioning correction of the IP address positioning library, the LBS positioning information can also be introduced as a reference, which specifically includes:

[0056] Step S301: Obtain the LBS positioning information of the user equipment and the IP point used by the user equipment.

[0057] Wherein, the LBS (Location Based Services) is a location-based service, which is to obtain the current location of a positioning device by using various types of positioning technology, and to provide information resources and basic services to the positioning device through mobile Internet. LBS is to obtain the geographic coordinate information of a user and other information based on a spatial database by using a wireless communication network (or a satellite positioning system) of a mobile terminal, and to provide the required location-related services to the user. The location of a user device obtained by LBS positioning information of the user device is more accurate than the location of the user device obtained by other methods.

[0058] Step S302: confirming the fourth positioning information corresponding to the IP point from the first IP address positioning library.

[0059] According to the IP point used by the user device, the fourth positioning information corresponding to the IP point can be found from the positioning information saved in the first IP address positioning library.

[0060] Step S303: if the LBS positioning information is inconsistent with the fourth positioning information, generating a correction record, and updating the fourth positioning information of the first IP address positioning library to the LBS positioning information according to the correction record.

[0061] Since the accuracy of the LBS positioning information is much higher than that of the first IP address positioning library, in the case where the LBS positioning information is inconsistent with the fourth positioning information, the fourth positioning information is directly corrected to the LBS positioning information, and the correction of the IP point by the LBS positioning information is noted through the correction record.

[0062] Further, since the accuracy of the LBS positioning information is high, on this basis, the positioning correction method can be further improved, specifically:

[0063] Step S401: obtaining the IP segment corresponding to the fourth positioning information.

[0064] Step S402: obtaining the fifth positioning information corresponding to the IP segment from the third positioning database.

[0065] Step S403: if the fifth positioning information is consistent with the fourth positioning information, updating the positioning information of the IP segment in the first IP address positioning library to the fifth positioning information.

[0066] Step S404: if the fifth positioning information is inconsistent with the fourth positioning information, updating the positioning information of the IP segment in the first IP address positioning library to the fourth positioning information.

[0067] When it is determined that the LBS location information of a user device is inconsistent with the fourth location information determined by the first IP address location database, the IP address used by the user device is first corrected. Then, using the IP address used by the user device as the starting point, the IP segment corresponding to the fourth location information in the first IP address location database is obtained, and the fifth location information corresponding to the IP segment is obtained from the third IP address location database. The fifth location information is compared with the corrected fourth location information. If they match, the fifth location information is used as the location information for the IP segment; if they do not match, the corrected fourth location information is used to correct the location information for the IP segment. In this embodiment, the third IP address location database can be any one of the following: Baidu IP database, Gaode IP database, Chunzhen IP database, Taobao IP database, and Evan Technology IP database.

[0068] This invention discloses a location correction method that, through open-source data and open APIs, uses a comparison processing method to easily and quickly fuse data from various IP address location databases, thereby improving the accuracy of IP location. Furthermore, it introduces IP location error correction, which, when other more accurate location technologies are available, corrects errors in the IP address location database, further improving the accuracy of the IP address location database.

[0069] It should be understood that, although attached Figure 1 The steps in the flowchart are shown sequentially according to the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order requirement for the execution of these steps, and they can be executed in other orders.
