Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a flow diagram of a method for locating an intelligent terminal according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step S110, generating corresponding WiFi description information according to the positioning reference information reported by each intelligent terminal, and storing the WiFi description information into a WiFi information database; wherein each piece of positioning reference information comprises one or more of the following: WiFi identification, base station identification and GPS information; each piece of WiFi description information includes: and reporting the intelligent terminal identification, the reporting time, the WiFi identification and the position information.
In this embodiment, the positioning reference information reported by the plurality of intelligent terminals is obtained, so that the mobile WiFi can be accurately determined according to the positioning reference information reported by the plurality of intelligent terminals.
And step S120, determining the mobile WiFi by comprehensively analyzing the WiFi description information in the WiFi information database.
When determining mobile WiFi, it is necessary to comprehensively analyze WiFi description information in the WiFi information database, for example, analyze a relationship between WiFi and a location and a relationship between WiFi and WiFi according to the WiFi description information, and then comprehensively determine which WiFi is mobile WiFi and which is fixed WiFi. During comprehensive analysis, the confidence of each WiFi may be determined according to the WiFi description information, and a confidence threshold is set, and when the confidence is greater than the threshold, the WiFi may be determined to be a fixed WiFi, and when the confidence is less than the threshold, the WiFi may be determined to be a mobile WiFi.
The reporting time can be used for removing the influence of old data, and data with too early time may fail or the condition that the mobile WiFi is changed into the fixed WiFi is not excluded, so that the influence is removed according to the reporting time, and the influence of the failed data on the determination of the mobile WiFi is avoided. In addition, the information reported by the same intelligent terminal at the same time can be determined according to the reported intelligent terminal identification and the reported time.
Step S130, when the intelligent terminal is positioned according to the positioning reference information reported by the intelligent terminal, mobile WiFi information in the positioning reference information reported by the intelligent terminal is filtered.
When the positioning is carried out, the mobile WiFi can influence the positioning accuracy of the intelligent terminal. For example, the determined mobile WiFi may be a mobile hotspot whose location changes with the movement of the smart terminal sending the WiFi signal, and if the location information of the WiFi hotspot is used as the positioning reference information of the smart terminal using the WiFi hotspot or scanning the WiFi hotspot, positioning may be inaccurate.
Through the determination of the steps, the mobile WiFi can be determined, when the WiFi information is needed to be utilized to position an intelligent terminal, the mobile WiFi information in the positioning reference information reported by the intelligent terminal can be filtered according to the determined mobile WiFi, namely the influence of the mobile WiFi on the position of the intelligent terminal is not considered, and the intelligent terminal can be accurately positioned. For example, it is determined in the above step that WiFi1 and WiFi2 are mobile WiFi, and when the intelligent terminal 1 is located, the reported location reference information includes WiFi1, WiFi2 and WiFi3, and then the intelligent terminal 1 is located only by using the location information of WiFi 3.
Therefore, by the technical scheme, the mobile WiFi information in the positioning reference information reported by the intelligent terminal can be filtered, so that the influence of the mobile WiFi information can be eliminated when the WiFi information is used for positioning the intelligent terminal, the accurate positioning of the intelligent terminal is realized, and the use experience of a user is enhanced.
In an embodiment of the present invention, the determining the mobile WiFi by comprehensively analyzing the WiFi description information in the WiFi information database in step S120 includes: analyzing the relation between WiFi and the position according to WiFi description information in a WiFi information database, and determining whether the WiFi is mobile WiFi or not according to the relation between the WiFi and the position; and/or analyzing the relationship between WiFi and WiFi according to WiFi description information in the WiFi information database, and determining whether the WiFi is mobile WiFi or not according to the relationship between the WiFi and the WiFi.
The mobile WiFi is a WiFi whose position is not fixed, and cannot be used for positioning service, so in this embodiment, the mobile WiFi can be determined by analyzing a relationship between the WiFi and the position; after the position of the mobile WiFi is changed, the WiFi that appears at the same time is changed along with the change of the position, so in this embodiment, the mobile WiFi can be determined by analyzing the relationship between the WiFi and the WiFi. In this embodiment, analyzing the relationship between WiFi and location, and analyzing the relationship between WiFi and WiFi may be implemented alone or in combination to determine mobile WiFi.
Specifically, the analyzing the relationship between the WiFi and the location according to the WiFi description information in the WiFi information database, and determining whether the WiFi is a mobile WiFi according to the relationship between the WiFi and the location includes: for a WiFi, calculating the probability of the WiFi appearing at a position according to the appearance frequency of the WiFi at the position; and if the probability of the WiFi appearing at more than two positions is greater than a first preset value, determining that the WiFi is the mobile WiFi.
In this embodiment, it may be determined whether WiFi is mobile WiFi by analyzing the relationship between WiFi and location. In the embodiment, once the probability of the occurrence of a WiFi in more than two positions is greater than the first preset value, the WiFi is determined to be mobile WiFi. The first preset value can be set according to the positioning requirement, and is not limited herein.
For example, WiFi identified as WiFi-a occurs at three locations, where the number of occurrences at location 1 is 20, the number of occurrences at location 2 is 10, and the number of occurrences at location 3 is 20, then it can be determined that the probability of WiFi occurrence at location 1 is 40%, the probability of WiFi occurrence at location 2 is 20%, and the probability of WiFi occurrence at location 3 is 40%. If the first preset value is 1%, this indicates that the probability of the WiFi identified as WiFi-a appearing at the above position 1, position 2 and position 3 is greater than the first preset value, which indicates that the mobility of the WiFi is very large, and it may be determined that the WiFi is mobile WiFi.
It should be noted that, the analysis of the relationship between WiFi and location may be obtained according to WiFi description information of a plurality of different smart terminal identifiers, for example, if the smart terminal a scans and reports WiFi identified as WiFi-a at location 1, it is determined that the WiFi identified as WiFi-a appears once at location 1, and if the smart terminal B scans and reports WiFi identified as WiFi-a at location 1, it is determined that the WiFi identified as WiFi-a appears 2 times at location 1, and the two are superimposed on each other.
Specifically, the analyzing the relationship between WiFi and WiFi according to the WiFi description information in the WiFi information database, and determining whether WiFi is mobile WiFi according to the relationship between WiFi and WiFi includes: for first positioning reference information and second positioning reference information reported by the same intelligent terminal or different intelligent terminals at different time, if the first positioning reference information comprises a designated WiFi mark and first other WiFi marks, the second positioning reference information comprises the designated WiFi mark and second other WiFi marks, and no intersection exists between the first other WiFi marks and the second other WiFi marks, the WiFi corresponding to the designated WiFi mark is mobile WiFi.
In this embodiment, whether WiFi is mobile WiFi may be determined by analyzing the relationship between WiFi and WiFi. When an intelligent terminal scans the WiFi, other WiFi can be scanned, if one WiFi is fixed WiFi, when one intelligent terminal scans the WiFi, the identification of the other scanned WiFi is stable, and if the WiFi is mobile WiFi, the identification of the other scanned WiFi is more variable when one intelligent terminal scans the WiFi. For example, the first positioning reference information reported by the intelligent terminal a at time 1 includes WiFi identified as WiFi-a, and also includes WiFi identified as WiFi-b, WiFi identified as WiFi-c, and WiFi identified as WiFi-d; however, when the second positioning reference information reported by the intelligent terminal a at time 2 includes WiFi identified as WiFi-a, WiFi identified as WiFi-e, WiFi identified as WiFi-f, and WiFi identified as WiFi-g. That is to say, except that WiFi-a is the same in WiFi included in the first positioning reference information and the second positioning reference information, other scanned WiFi are different and do not intersect, which indicates that WiFi-a moves, and it is determined that WiFi-a is mobile WiFi.
It should be noted that, here, the analysis of the relationship between WiFi and WiFi may be obtained according to WiFi description information of a plurality of different smart terminal identifications, for example, when the smart terminal a scans WiFi-a, WiFi-B, WiFi-c, WiFi-d, and smart terminal B scans WiFi-a, WiFi-e, WiFi-f, WiFi-g, it may be determined that WiFi identified as WiFi-a is mobile WiFi.
In one embodiment of the present invention, the method shown in fig. 1 further comprises: and when the WiFi is determined to appear at other positions after the appointed position appears in the time sequence by comprehensively analyzing the WiFi description information in the WiFi information database, and the time of the last appearance at the appointed position is more than a first preset time length from the current time, deleting the WiFi description information containing the identification of the WiFi and the information of the appointed position from the WiFi information database.
When filtering the mobile WiFi, the comprehensive analysis is carried out on the total data in the WiFi information database, so that the data which have no reference meaning to positioning actually are deleted in order to eliminate the influence of invalid data and ensure the storage space of the WiFi information database. For example, a WiFi that is determined to be mobile may become fixed, i.e., the location of the WiFi is not moving, and the determination of the WiFi may be affected if it ever appears at another location. Therefore, in this embodiment, the reporting time in the WiFi description information may be used to remove the old data, so as to avoid the influence of the invalid data on the determination of the mobile WiFi. For example, if a WiFi appears at position 2 after position 1 appears in chronological order, and the last time the WiFi appears at position 1 is more than 15 days from the current time, that is, the WiFi does not appear at position 1 within the 15 days, the WiFi description information including the identification of the WiFi and the information of the designated position is deleted from the WiFi information database. Therefore, the data in the WiFi information database are deleted, the database can be maintained, and the storage space of the database is ensured.
In one embodiment of the present invention, the method shown in fig. 1 further comprises: and when the specified WiFi which is determined to be the mobile WiFi is determined to be in the same position within the second latest preset length of time by comprehensively analyzing the WiFi description information in the WiFi information database, changing the specified WiFi into the fixed WiFi.
And when the mobile WiFi is determined, the mobile WiFi is determined according to the positioning reference information reported by each intelligent terminal in real time. If a fixed WiFi is moved, the fixed WiFi is determined to be mobile WiFi for a certain time after being moved. For example, if a user using fixed WiFi identified as WiFi-a moves from old home location a to new home location b, the fixed WiFi identified as WiFi-a will be determined as mobile WiFi during the time, but the location of the WiFi identified as WiFi-a will not change after moving to the new home location, and the WiFi identified as WiFi-a can be used to perform positioning of the smart terminal, and the WiFi identified as WiFi-a needs to be determined as fixed WiFi again. Therefore, in this embodiment, when a designated WiFi that has been determined to be a mobile WiFi appears at the same position within a second predetermined time (for example, a week), the designated WiFi is changed to a fixed WiFi, so that the WiFi that is changed to the fixed WiFi is used for positioning service.
Fig. 2 is a schematic structural diagram of an apparatus for locating an intelligent terminal according to an embodiment of the present invention. As shown in fig. 2, the apparatus 200 for locating a smart terminal includes:
the database maintenance unit 210 is adapted to generate corresponding WiFi description information according to the positioning reference information reported by each intelligent terminal and store the WiFi description information in a WiFi information database; wherein each piece of positioning reference information comprises one or more of the following: WiFi identification, base station identification and GPS information; each piece of WiFi description information includes: and reporting the intelligent terminal identification, the reporting time, the WiFi identification and the position information.
In this embodiment, the positioning reference information reported by the plurality of intelligent terminals is obtained, so that the mobile WiFi can be accurately determined according to the positioning reference information reported by the plurality of intelligent terminals.
The mobile WiFi determining unit 220 is adapted to determine the mobile WiFi by comprehensively analyzing the WiFi description information in the WiFi information database.
When determining mobile WiFi, it is necessary to comprehensively analyze WiFi description information in the WiFi information database, for example, analyze a relationship between WiFi and a location and a relationship between WiFi and WiFi according to the WiFi description information, and then comprehensively determine which WiFi is mobile WiFi and which is fixed WiFi. During comprehensive analysis, the confidence of each WiFi may be determined according to the WiFi description information, and a confidence threshold is set, and when the confidence is greater than the threshold, the WiFi may be determined to be a fixed WiFi, and when the confidence is less than the threshold, the WiFi may be determined to be a mobile WiFi.
The reporting time can be used for removing the influence of old data, and data with too early time may fail or the condition that the mobile WiFi is changed into the fixed WiFi is not excluded, so that the influence is removed according to the reporting time, and the influence of the failed data on the determination of the mobile WiFi is avoided. In addition, the information reported by the same intelligent terminal at the same time can be determined according to the reported intelligent terminal identification and the reported time.
The positioning unit 230 is adapted to filter mobile WiFi information in the positioning reference information reported by an intelligent terminal when the intelligent terminal is positioned according to the positioning reference information reported by the intelligent terminal.
When the positioning is carried out, the mobile WiFi can influence the positioning accuracy of the intelligent terminal. For example, the determined mobile WiFi may be a mobile hotspot whose location changes with the movement of the smart terminal that transmits the WiFi signal, and if the location information of the WiFi hotspot is used as the location reference information for locating the smart terminal that used the WiFi hotspot once, the location of the smart terminal that used the WiFi hotspot once or scanned the WiFi hotspot may be inaccurate.
Through the determination of the scheme, the mobile WiFi can be determined, when the WiFi information is required to be utilized to position an intelligent terminal, the mobile WiFi information in the positioning reference information reported by the intelligent terminal can be filtered according to the determined mobile WiFi, namely the influence of the mobile WiFi on the position of the intelligent terminal is not considered, and the intelligent terminal can be accurately positioned. For example, in the above scheme, it is determined that WiFi-1 and WiFi2 are mobile WiFi, and when the intelligent terminal 1 is located, the location reference information reported by the intelligent terminal 1 includes WiFi1, WiFi2 and WiFi3, the intelligent terminal 1 is located only by using the location information of WiFi 3.
Therefore, by the technical scheme, the mobile WiFi information in the positioning reference information reported by the intelligent terminal can be filtered, so that the influence of the mobile WiFi information can be eliminated when the WiFi information is used for positioning the intelligent terminal, the accurate positioning of the intelligent terminal is realized, and the use experience of a user is enhanced.
In an embodiment of the present invention, the mobile WiFi determining unit 220 is adapted to analyze a relationship between WiFi and a location according to WiFi description information in the WiFi information database, and determine whether WiFi is mobile WiFi according to the relationship between WiFi and the location; and/or the mobile terminal is suitable for analyzing the relation between WiFi and WiFi according to WiFi description information in the WiFi information database and determining whether the WiFi is mobile WiFi or not according to the relation between the WiFi and the WiFi.
The mobile WiFi is a WiFi whose position is not fixed, and cannot be used for positioning service, so in this embodiment, the mobile WiFi can be determined by analyzing a relationship between the WiFi and the position; after the position of the mobile WiFi is changed, the WiFi that appears at the same time is changed along with the change of the position, so in this embodiment, the mobile WiFi can be determined by analyzing the relationship between the WiFi and the WiFi. In this embodiment, analyzing the relationship between WiFi and location, and analyzing the relationship between WiFi and WiFi may be implemented alone or in combination to determine mobile WiFi.
Specifically, the mobile WiFi determining unit 220 is adapted to calculate, for a WiFi, a probability of the WiFi appearing at a location according to an appearance frequency of the WiFi at the location, and determine that the WiFi is a mobile WiFi when the probabilities of the WiFi appearing at two or more locations are greater than a first preset value.
In this embodiment, it may be determined whether WiFi is mobile WiFi by analyzing the relationship between WiFi and location. In the embodiment, once the probability of the occurrence of a WiFi in more than two positions is greater than the first preset value, the WiFi is determined to be mobile WiFi. The first preset value can be set according to the positioning requirement, and is not limited herein.
For example, WiFi identified as WiFi-a occurs at three locations, where the number of occurrences at location 1 is 20, the number of occurrences at location 2 is 10, and the number of occurrences at location 3 is 20, then the probability of the WiFi occurring at location 1 may be determined to be 40%, the probability of the WiFi occurring at location 2 may be determined to be 20%, and the probability of the WiFi occurring at location 3 may be determined to be 40%. If the first preset value is 1%, this indicates that the probability of the WiFi identified as WiFi-a appearing at the above position 1, position 2 and position 3 is greater than the first preset value, which indicates that the mobility of the WiFi is very large, and it may be determined that the WiFi is mobile WiFi.
It should be noted that, the analysis of the relationship between WiFi and location may be obtained according to WiFi description information of a plurality of different smart terminal identifiers, for example, if the smart terminal a scans and reports WiFi identified as WiFi-a at location 1, it is determined that the WiFi identified as WiFi-a appears once at location 1, and if the smart terminal B scans and reports WiFi identified as WiFi-a at location 1, it is determined that the WiFi identified as WiFi-a appears 2 times at location 1, and the two are superimposed on each other.
Specifically, the mobile WiFi determining unit 220 is adapted to determine, for a first positioning reference information and a second positioning reference information reported by the same intelligent terminal or different intelligent terminals at different times, that WiFi corresponding to a specified WiFi identifier is mobile WiFi when the first positioning reference information includes the specified WiFi identifier and a first other WiFi identifier, the second positioning reference information includes the specified WiFi identifier and a second other WiFi identifier, and there is no intersection between the first other WiFi identifier and the second other WiFi identifier.
In this embodiment, whether WiFi is mobile WiFi may be determined by analyzing the relationship between WiFi and WiFi. When an intelligent terminal scans the WiFi, other WiFi can be scanned, if one WiFi is fixed WiFi, when one intelligent terminal scans the WiFi, the identification of the other scanned WiFi is stable, and if the WiFi is mobile WiFi, the identification of the other scanned WiFi is more variable when one intelligent terminal scans the WiFi. For example, the first positioning reference information reported by the intelligent terminal a at time 1 includes WiFi identified as WiFi-a, and also includes WiFi identified as WiFi-b, WiFi identified as WiFi-c, and WiFi identified as WiFi-d; however, when the second positioning reference information reported by the intelligent terminal a at time 2 includes WiFi identified as WiFi-a, WiFi identified as WiFi-e, WiFi identified as WiFi-f, and WiFi identified as WiFi-g. That is to say, except that WiFi-a is the same in WiFi included in the first positioning reference information and the second positioning reference information, other scanned WiFi are different and do not intersect, which indicates that WiFi-a moves, and it is determined that WiFi-a is mobile WiFi.
It should be noted that, here, the analysis of the relationship between WiFi and WiFi may be obtained according to WiFi description information of a plurality of different smart terminal identifications, for example, when the smart terminal a scans WiFi-a, WiFi-B, WiFi-c, WiFi-d, and smart terminal B scans WiFi-a, WiFi-e, WiFi-f, WiFi-g, it may be determined that WiFi identified as WiFi-a is mobile WiFi.
In an embodiment of the present invention, the database maintenance unit 210 is further adapted to delete WiFi description information containing an identifier of a WiFi and information of a specified location from the WiFi information database when it is determined that a WiFi appears at another location after the specified location appears in a time sequence by comprehensively analyzing WiFi description information in the WiFi information database, and a time when the WiFi appears at the specified location for the last time is more than a first preset time length from a current time.
When filtering the mobile WiFi, the comprehensive analysis is carried out on the total data in the WiFi information database, so that the data which have no reference meaning to positioning actually are deleted in order to eliminate the influence of invalid data and ensure the storage space of the WiFi information database. For example, a WiFi that is determined to be mobile may become fixed, i.e., the location of the WiFi is not moving, and the determination of the WiFi may be affected if it ever appears at another location. Therefore, in this embodiment, the reporting time in the WiFi description information may be used to remove the old data, so as to avoid the influence of the invalid data on the determination of the mobile WiFi. For example, if a WiFi appears at position 2 after position 1 appears in chronological order, and the last time the WiFi appears at position 1 is more than 15 days from the current time, that is, the WiFi does not appear at position 1 within the 15 days, the WiFi description information including the identification of the WiFi and the information of the designated position is deleted from the WiFi information database. Therefore, the data in the WiFi information database are deleted, the database can be maintained, and the storage space of the database is ensured.
In an embodiment of the present invention, the mobile WiFi determining unit 220 is further adapted to change a specific WiFi that has been determined to be a mobile WiFi to a fixed WiFi when it is determined that the specific WiFi is present at the same position within a second preset time period.
And when the mobile WiFi is determined, the mobile WiFi is determined according to the positioning reference information reported by each intelligent terminal in real time. If a fixed WiFi is moved, the fixed WiFi is determined to be mobile WiFi for a certain time after being moved. For example, if a user using fixed WiFi identified as WiFi-a moves from old home location a to new home location b, the fixed WiFi identified as WiFi-a will be determined as mobile WiFi during the time, but the location of the WiFi identified as WiFi-a will not change after moving to the new home location, and the WiFi identified as WiFi-a can be used to perform positioning of the smart terminal, and the WiFi identified as WiFi-a needs to be determined as fixed WiFi again. Therefore, in this embodiment, when a designated WiFi that has been determined to be a mobile WiFi appears at the same position within a second predetermined time (for example, a week), the designated WiFi is changed to a fixed WiFi, so that the WiFi that is changed to the fixed WiFi is used for positioning service.
