It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 illustrates an exemplary system architecture 100 to which the method or apparatus for determining location information of embodiments of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include terminals 101, 102, 103, a network 104, and a server 105. The network 104 may be the medium used to provide communication links between the terminals 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The user may use the terminals 101, 102, 103 to interact with the server 105 via the network 104 to receive or send messages or the like. The terminals 101, 102, 103 may have various client applications installed thereon, such as a map-like application, a web browser, a shopping-like application, an instant messenger, and the like.
Here, the terminals 101, 102, and 103 may be hardware or software. When the terminals 101, 102, 103 are hardware, they may be various electronic devices with display screens, including but not limited to smart phones, tablet computers, smart watches, e-book readers, MP3 players (Moving Picture Experts Group Audio Layer III, mpeg Audio Layer 3), laptop portable computers, desktop computers, and the like. When the terminals 101, 102, 103 are software, they can be installed in the electronic devices listed above. It may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services) or as a single piece of software or software module. And is not particularly limited herein.
The server 105 may be a server providing various services, for example, may be a background server providing support for various applications installed on the terminals 101, 102, 103. If there is a mobile device capable of accessing the internet through a mobile network in the terminals 101, 102, and 103, the background server may obtain the positioning data of the IP address of the mobile device through a satellite and/or a base station in the process of using the mobile device by the user. Meanwhile, the background server can also acquire the IP data dictionary from the cloud. In this way, the backend server may analyze and process the acquired data, and may return a processing result (e.g., current location information of the IP address) to the terminals 101, 102, and 103, or may store the processing result in a local or cloud environment, and the like.
Here, the server 105 may be hardware or software. When the server 105 is hardware, it may be implemented as a distributed server cluster composed of a plurality of servers, or may be implemented as a single server. When the server 105 is software, it may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be noted that the method for determining the location information provided in the embodiment of the present application is generally performed by the server 105. Accordingly, the means for determining location information is typically provided in the server 105.
It should be understood that the number of terminals, networks, and servers in fig. 1 are merely illustrative. There may be any number of terminals, networks, and servers, as desired for an implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for determining location information in accordance with the present application is shown. The method for determining location information may comprise the steps of:
In this embodiment, an executing body (for example, the server 105 shown in fig. 1) of the method for determining the location information may acquire the real-time location data of the target IP address by using various existing location methods. The destination IP address may be any of various IP addresses currently used. And the positioning data may typically include location information and positioning time for the IP address. Here, the representation of the location information is not limited in the present application, and may be, for example, latitude and longitude coordinates, a communication address, a building name, or the like.
In this embodiment, the positioning manner may include (but is not limited to) at least one of the following: GPS, BeiDou Navigation Satellite System (BDS), GLONASS Satellite Navigation System (GLONASS), base station positioning, bluetooth positioning, and the like.
For example, when a user uses a terminal (e.g., the terminal 101, 102, 103 shown in fig. 1) to perform an operation related to a location, such as a user opening a map application on the terminal to perform navigation or location search, or uses the terminal to perform weather query and search for a sharing bicycle; and if the application of the user on the terminal releases the state, setting the position to be visible, and the like. At this time, the execution body may employ a satellite positioning technique to acquire real-time positioning data of the IP address of the terminal.
For another example, when the terminal is in a network connection state and a user uses the terminal to perform a call, send and receive a short message, or browse a web page, the execution main body may also obtain real-time location data of an IP address of the terminal through a base station location technology.
In this embodiment, the execution body may query the effective duration of the target IP address according to a pre-stored IP data dictionary. The IP data dictionary may be used to describe attribute information of an IP address. The attribute information herein may include, but is not limited to, the type and/or validity duration of the IP address. The valid duration may be used to represent a duration in which the location of the IP address remains unchanged, i.e., a duration in which the location of the IP address is at the same location.
In view of the IP address allocation method, the types of the IP addresses can be mainly classified into the following three types: 1) private IP leased by enterprise organizations from operators. The location of such IPs is very fixed, distributed in the owner's office, covering a radius of about 100 meters. Because the position of the device is fixed for a long time, the effective time generally reaches about one week. 2) Home broadband. Typically enjoyed by an entire cell, covering up to 500 meters in radius. The effective duration of the IP varies from hours to days. 3) Mobile networks (e.g., 2/3/4/5G) IP. These IPs are distributed by very large gateways, with up to several hundred thousand users under one IP. The user location spans many hundreds of kilometers and the location varies very much in a short time. Therefore, according to the characteristics, the type and the effective time length of the IP address can be determined from the aspects of the number of IP users, the change radius of the IP position, the change rate of the IP time and the like.
In some optional implementations of this embodiment, the attribute information of the IP address may include an effective duration. That is, the validity duration of the IP address is included in the IP data dictionary. At this time, the execution body may directly query the IP data dictionary for the effective duration of the target IP address.
Alternatively, the attribute information of the IP address may include the type of the IP address. That is, the IP data dictionary includes the type of IP address. At this time, the execution body may look up the type of the target IP address in the IP data dictionary. In this way, the execution subject can determine the effective duration of the target IP address according to the type obtained by the query.
For example, the execution principal may obtain the validity duration of this type of IP address from a cloud query. As another example, the execution principal may query the validity duration of this type of IP address from a pre-stored file. Wherein, the corresponding relation between the type of the IP address and the effective duration is recorded in the file. The file may be preset by the user; or by collecting the validity duration of different types of IP addresses and performing statistical analysis on the data.
It will be appreciated that where the type of IP address is a mobile network, the enforcement agent may determine the current location of the IP address by the positioning techniques described above. Therefore, after querying the type of the target IP address, the executing entity may determine whether the type is a mobile network. And in case that the type of the target IP address is determined to be a mobile network, the following steps of the method in this embodiment may not be continuously performed. Therefore, the resource occupation of the execution main body can be reduced, and the data processing efficiency is improved.
Here, the IP data dictionary may be generated using published IP data (e.g., IP address, type, location, etc.). The IP data dictionary may also be generated by collecting a large amount of historical positioning data and analyzing the data. The storage location of the IP data dictionary is not limited in the present application, and may be stored in a cloud or a database server.
And step 203, performing track segmentation on the real-time positioning data of the target IP address according to the effective duration of the target IP address.
In this embodiment, the execution main body may perform track segmentation on the real-time location data of the target IP address according to the effective duration of the target IP address. Wherein each track segment may include at least one positioning datum.
In some optional implementations of this embodiment, the execution subject may determine whether the duration of acquiring the real-time location data of the target IP address reaches the valid duration. And if the time length for acquiring the real-time positioning data of the target IP address is determined to reach the effective time length, the corresponding positioning data can be segmented into the same section of track, namely, the same section of track.
For example, when the execution main body acquires the first piece of real-time positioning data of the target IP address, timing may be started until the timing duration reaches the effective duration. At this time, the execution body may divide the positioning data acquired within the effective time period of the timing into the same track. For another example, when the execution main body acquires the first piece of real-time positioning data of the target IP address, the positioning time therein may be used as the start time. The end time, i.e. the start time plus the validity period, may be determined in combination with the validity period. At this time, the execution body may divide the positioning data with the positioning time between the start time and the end time into the same track.
Alternatively, in order to improve the data processing efficiency while ensuring the accuracy of the determination result (i.e., the position of the target IP address), the execution main body may determine not only whether the acquisition duration reaches the effective duration but also whether the number of pieces of the acquired real-time positioning data of the target IP address reaches the preset threshold. If the execution main body determines that the acquired duration reaches the effective duration or determines that the acquired number reaches a preset threshold (for example, 10), the corresponding positioning data can be segmented into the same section of track. That is, in the case where either one of the effective time length and the preset threshold is reached, the trajectory segmentation may be performed. For example, the execution body may divide the acquired preset threshold pieces of positioning data into the same track. The preset threshold may be set according to actual conditions (such as the type of the IP address and the memory of the execution main body).
And step 204, analyzing the positioning data of the latest track segment, and determining the current position information of the target IP address.
In this embodiment, according to the track segment obtained by splitting in step 203, the execution main body may analyze each positioning data in the latest track segment, so as to determine the current location information of the target IP address. The newest track segment here generally refers to the track segment that is closest to the current time. Namely, in each track segment obtained by segmenting according to the time sequence, the track segment obtained by segmenting is obtained finally.
In some optional implementations of this embodiment, the execution subject may perform statistical analysis on the position information in each positioning data in the latest track segment. So that the current location of the target IP address can be determined based on the results of the statistical analysis. For example, the execution body may count the same location information in each positioning data, and may take the location information in the positioning data having the same location information and the largest number as the current location of the target IP address. The same location herein may refer to a location that is geographically identical; but may also refer to a geographical location within a predetermined range (e.g., 10 meters) of distance. For another example, the execution subject may also perform cluster analysis on the location information in each positioning data, so that the location of the cluster center may be used as the current location of the target IP address.
Alternatively, to improve the accuracy of the determination result, the executing entity may cluster the position information in the positioning data of the latest track segment, resulting in the center position and the radius of the class. At this time, the execution body may use the center position and the radius of the obtained class as the center position and the radius of the coverage of the target IP address, respectively, that is, the current position of the target IP address.
It can be understood that, the method in this embodiment may implement the positioning of the IP address of the non-mobile network user by using the principle that the IP address in the positioning data and the IP address in the IP data dictionary coexist, so that a user with a larger range may be positioned, that is, the coverage of the user may be expanded. For example, internet IP addresses of all connected users in the same wifi (Wireless Fidelity, Wireless local area network) are often the same. Under the environment, the IP address and the current position of the mobile phone user can be acquired. When a PC (personal computer) user is on the internet in the same wifi environment, the PC user has the same IP address as the mobile phone user, but no positioning information. We can know the location of the PC user by the location of the IP address contributed by the mobile phone user. Therefore, the positioning problem of a PC end or other users without positioning capability can be solved, and the user requirements can be further met.
In addition, the position accuracy of the disclosed IP data dictionary is usually poor, and the accuracy can only reach over 50 km, so that the actual application requirement of accurate positioning cannot be met. And the IP data dictionary cannot be updated in real time, and the data is most likely to be invalid. The method in this embodiment uses a plurality of time-sensitive positioning data to determine the current location of the IP address. Therefore, the problems of precision and timeliness of the IP data dictionary can be effectively solved, and the positioning accuracy is improved.
In the method for determining location information in this embodiment, the valid duration of the target IP address may be obtained by querying through a pre-stored IP data dictionary. And then, according to the effective duration of the target IP address, performing track segmentation on the acquired real-time positioning data of the target IP address. Then, the positioning data of the latest track segment is analyzed, and the current position information of the target IP address can be determined. That is, by using the co-occurrence principle of the IP address in the positioning data and the IP address in the IP data dictionary, the IP address of the non-mobile network user can be positioned, which is helpful for positioning a wider range of users. Meanwhile, the current position information of the IP address is determined by adopting a plurality of pieces of positioning data with higher timeliness, so that the positioning accuracy is improved.
Referring to fig. 3, a flow 300 of yet another embodiment of a method for determining location information according to the present application is shown. The method for determining location information may comprise the steps of:
In the present embodiment, an executing body (for example, the server 105 shown in fig. 1) of the method for determining the location information acquires the real-time location data of the target IP address through a plurality of location manners. The positioning data may generally include location information of the IP address and a positioning time. Reference may be made to the related description in step 201 of the embodiment in fig. 2, and details are not repeated here.
In this embodiment, the IP data dictionary may be used to describe attribute information of an IP address. The attribute information of the IP address may include a type and an effective duration of the IP address. I.e. the IP data dictionary includes the type and validity duration of the IP address. At this time, the execution body may query the type of the target IP address in the IP data dictionary, and may determine whether the queried type is a mobile network.
The Mobile network (Mobile web) herein generally refers to a manner of connecting to a public network using a Mobile device, such as a Mobile phone, a palm top computer or other portable means, to enable internet access. Mobile networks do not require fixed equipment for access. Mainly operator provided networks such as 2, 3, 4, 5G.
Here, if the execution body determines that the type of the target IP address is a mobile network, the location information in the acquired real-time location data of the target IP address may be used as the current location of the target IP address. If the executing agent determines that the type of the target IP address is not a mobile network, then execution may proceed to step 303.
In this embodiment, if the execution body determines in step 302 that the type of the target IP address is not a mobile network, the execution body may continue to query the IP data dictionary for the valid duration of the target IP address.
And step 304, performing track segmentation on the real-time positioning data of the target IP address according to the effective duration of the target IP address.
In this embodiment, the execution main body may perform track segmentation on the real-time location data of the target IP address according to the effective duration of the target IP address. Wherein each track segment may include at least one positioning datum. Reference may be made to the related description in step 203 of the embodiment in fig. 2, and details are not repeated here.
In this embodiment, the executing entity may cluster the position information in the positioning data of the latest track segment, thereby obtaining the center position and the radius of the class. And the obtained center position and radius of the class can be respectively used as the center position and the coverage radius of the target IP address to determine the current position of the target IP address.
In this embodiment, in order to implement real-time positioning of the IP address, the current location information of the target IP address may further include the valid time of the current location. At this time, the execution body may analyze the positioning time in the positioning data of the latest track segment, thereby obtaining the time of the track segment. In this way, the execution body may determine the valid time of the current location of the target IP address by combining the time of the track segment and the valid duration of the target IP address.
For example, the execution subject may use the positioning time in the last positioning data in the track segment as the time of the track segment according to the chronological order. I.e. the positioning time closest to the current time is taken as the time of the track segment. For another example, the execution subject may use the middle value of the time range in which each positioning time is located, or the positioning time in the middle positioning data in each piece of positioning data as the time of the track segment. Then, the execution body may add the time of the track segment to the effective duration of the target IP address to obtain an effective deadline of the current location of the target IP address. At this time, the execution body may take the effective deadline as the effective time; the time of the latest track segment and the obtained valid cut-off time can be used as two end values of the valid time respectively.
It will be appreciated that while the positioning data obtained by the positioning techniques described above is generally accurate, these positioning approaches generally do not address the positioning of non-mobile network users. And the resulting positioning data is often time-discrete. Namely, only a plurality of historical time points can not realize real-time positioning. The method in the embodiment can realize the positioning of the non-mobile network user, thereby being beneficial to expanding the coverage of the user. And the current position of the user is determined by adopting a plurality of pieces of positioning data with timeliness, so that the positioning accuracy is improved. In addition, the time dispersion problem of the positioning data can be improved by adding the effective time in the current position information of the target IP address, so that the coverage of time is increased, and the real-time positioning is favorably realized.
In this embodiment, after determining the current location information of the target IP address, the execution main body may further store the target IP address and the current location information of the target IP address in a key-value pair manner, so as to generate a location query database. Wherein the location query database may be used to query current location information for the IP address.
It should be noted that the storage location of the location query database is not limited in the present application, and may be stored in a local, cloud, or other database server of the execution subject. Therefore, the IP address to be inquired is input into the position inquiry database, and the current position of the IP address can be obtained. Further, by using the current location of the IP address, better internet services such as advertisements or store recommendations can be performed.

Therefore, effective time can be added in the current position information of the IP address of the mobile network, and real-time positioning is facilitated.
In the method for determining the location information in this embodiment, by adding the effective time to the current location information of the IP address, the time dispersion problem of the location data can be improved, so that the coverage of time is increased, and real-time location is facilitated. In addition, the current position information of the determined IP address is stored to generate a position query database, so that the real-time positioning of the IP address can be facilitated.
With further reference to fig. 4, fig. 4 is a schematic diagram of an application scenario of the method for determining location information according to the above embodiments. In the application scenario of fig. 4, both terminals 101, 102 used by the user are connected to the same wifi signal. I.e. the terminals 101, 102 have the same IP address. When a user searches for a location using mapping software installed on the terminal 101, the server 105 providing background support for the mapping software may run a method for determining location information, including:
first, real-time location data 401 of the IP address of the terminal 101 may be obtained; then, the effective duration of the target IP address can be obtained by searching in the pre-stored IP data dictionary 402; then, according to the effective duration of the target IP address, the real-time location data 401 of the target IP address can be subjected to track segmentation to obtain different track segments 403; finally, the positioning data of the latest track segment 403 is analyzed to determine the current position information 404 of the target IP address.
Furthermore, when the user browses the web page using the terminal 102, the server 105 may filter recommended information (e.g., advertisement, news, etc.) in the web page according to the current location of the IP address of the terminal 102, and may transmit the filtered recommended information to the terminal 102. Therefore, the recommendation information can be richer and more targeted, the user requirements can be better met, and the user experience can be improved.
