1 is a diagram illustrating an AP information collecting device and an access point located around the AP information collection device according to an embodiment of the present invention.

The AP information collecting device 100 may collect IP information of access points (APs) 101 to 103 located in the vicinity. At this time, the access point 101 to 103 to which the AP information collection device 100 attempts to connect and transmits the public IP information of the AP to the local information determination system is an access point that does not have a separate security setting. In some cases, information on a secure access point may be collected. The AP information collecting device 100 sets up an Internet connection through the access points 101 to 103, and the AP information collecting device 100 connects to each of the access points 101 to 103 via the GPS satellite 104. You can check the location information. That is, the AP information collecting device 100 secures an Internet connection through the access points 101 to 103, thereby enabling the IP information assigned to the access points 101 to 103 connected to the Internet.

The AP information collecting device 100 may transmit the IP information of the access points 101 to 103 and the location information of the AP information collecting device 100 to the local information determining system 105. The area information determination system 105 may determine area information, which is an administrative area corresponding to the IP information, using the received IP information of the access points 101 to 103 and the location information of the AP information collecting device 100.

The process of converting the primary location information collected in the form of GPS coordinates into another type of secondary location information about the location may be performed by the local information determination system. Conversion to secondary location information may mean conversion to administrative area information related to the primary location information, but is not limited thereto and may include conversion to an arbitrary geographic name that can be utilized for the implementation of location-based services. Can be.

The process of converting the second location information, that is, the area information determination, may be performed by a separate area information determination system that is distinguished from the AP information collecting device 100. The area information determining unit may be combined with the AP information collecting device 100, and in this case, location information (including primary and / or secondary location information) from a plurality of vehicles equipped with the AP information collecting device may be separated. Can be collected and managed.

On the other hand, the primary location information collected in the form of GPS coordinates can be transferred to the regional information management system and utilized as the form itself. In addition to services based on transformed local information, such as administrative districts, location-based services using physical coordinates can also be provided. Can be. In this case, the area information management system may be implemented in a form in which the area information determination unit is omitted in the area information determination system described below, and the operation of other components may be understood with reference to the following description regarding the area information determination system. have. IP by another server that provides location-based services for the local information determination (management) system described below. Of course, it is possible to provide a technical means such as an API that enables the use of location information (or local information converted location information).

As shown in FIG. 1, the AP information collecting device 100 may be mounted in a movable vehicle. To this end, the AP information collecting device 100 may include a Wi-Fi antenna that collects IP information by accessing an access point. Also, the AP information collecting device 100 may include a GPS antenna for receiving GPS information, which is location information of the AP information collecting device 100, from the satellite 104.

In this case, the Wi-Fi antenna may be a directional antenna or an omnidirectional antenna. The omnidirectional antenna may be configured to be folded in consideration of the height of the vehicle. And, the directional antenna can be adjusted up and down angle.

In the present invention, a protocol used for communication between each access point and the AP information collecting device 100 is not limited to a specific one, and any protocol for providing short-range wireless communication may be utilized for implementing the present invention.

2 is a block diagram showing the configuration of an AP information collecting device according to an embodiment of the present invention.

Referring to FIG. 2, the AP information collecting device 202 may include an AP identification unit 204, an AP connection unit 205, an information transfer unit 206, and a DB generator 207.

The AP identification unit 204 may scan and identify the access point 201 located in the vicinity. In detail, the AP identification unit 204 may scan at least one access point located in the vicinity by transmitting a signal through the antenna.

The AP information collecting device 202 may collect the IP information by identifying the access point 201 indicating the preset communication strength or more. In general, as the distance between the AP information collecting device 202 and the access point 201 increases, the communication strength from the access point 201 tends to be weakened. Therefore, to make the access point 201 showing the above-mentioned communication strength or higher as the object of collecting the IP information, the access point within a certain radius from the position of the AP information collecting device 202 (the reference point of the measured GPS position information). There is an effect of limiting the IP address information collection target to 201. This is an indirect means of ensuring a strong association between the IP information of the access point 201 and the location information of the AP information collecting device 202 used to identify the corresponding relationship between the IP information and the area information.

Alternatively, the AP information collecting device 202 may identify the access point 201 indicating the communication strength that falls within a preset rank from all scanned access points. For example, in the suburban area, since the communication strength does not appear strong, the access point 201 may be identified by considering the relative communication diagram rather than the absolute communication strength.

As mentioned in FIG. 1, since the AP information collecting device 202 may be mounted on the moving object, a signal reception state with the access point 201 may be changed according to the moving process of the moving object. That is, as the mobile object equipped with the AP information collecting device 202 approaches the access point 201, the signal communication strength increases, so that the AP information collecting device 202 may connect to the Internet through the access point 201. The number of identified access points is unlimited.

The AP connector 205 can connect to the Internet through the identified access point 201. For example, the AP connection unit 205 may determine the location information of the AP information collecting device 202 at the time when the Internet connection is established through the identified access point 201 through an Internet protocol such as TCP / IP. 208). That is, according to one embodiment of the present invention, the location information of the AP information collecting device 202 is the location information at the time of being connected to the Internet through the access point 201. Thus, the association between the location information of the AP information collecting device 202 and the IP information of the access point 201 can be ensured. In particular, the AP information collection device 202 collects IP information and AP information of the access point 201 by accessing an access point 201 located in a closer position in consideration of communication strength than a remote access point 201. A strong association between the location information of the device 202 may be formed. Due to this association, the IP information of the access point 201 and the region information corresponding to the location information of the AP information collecting device 202 may be matched with each other.

The change in communication strength with a particular access point may be recorded by the AP information collecting device 202. The recorded change in communication strength can be used to improve the accuracy of the information of the local information decision.

When the AP information collection device 202 establishes an Internet connection with a specific access point 201, the location information associated with the AP information collection device 202 (in some cases, converted secondary location information) through the Internet connection. Is transmitted to the area information determination system 208 (area information management system, if the conversion is completed). This transmission allows the local information determination system 208 to obtain IP information of the corresponding access point 201.

When the transmission is completed, the AP information collecting device 202 terminates the Internet connection for connection with another access point, but recording the sensitivity of the communication with the access point even after the location information transmission and the termination of the Internet connection are completed. It may be recorded together with the location information of 202. This record can be used to determine the location information used in determining local information relevant to the IP of the access point. In determining local information related to a specific IP, location information showing a relatively high communication strength with an access point allocated with the corresponding IP may be considered as more reliable information. This record may be transmitted to the local information determination system via a communication connection other than an internet connection through the target access point where the local information for the assigned IP is determined.

On the other hand, even when the converted second location information (local information) is transmitted to the local information management system based on the measured primary location information, the information on the location showing a relatively high communication strength with the access point is higher. It can be used as information having reliability.

The information delivery unit 206 may deliver the IP information assigned to the access point 201 to the local information determination system 208. At this time, the area information determination system 208 may determine area information corresponding to the IP information assigned to the access point 201. The information transfer unit 206 corresponds to the source information according to the TCP / IP standard when the AP connection unit 205 connects to the Internet through the access point 201 and transmits the location information to the local information determination system 208 through the Internet protocol. The public IP of the access point 201 can be confirmed. Then, the information delivery unit 206 may deliver the identified public IP to the local information determination system 201.

If there are a plurality of identified access points, the information transfer unit 206 may collect IP information of the access point 201 connected through the interface capable of multiple access at once and deliver it to the local information determination system 208.

The DB generator 207 may generate the database 203 by matching the MAC address of the access point 201, the public IP, and the location information of the AP information collecting device 202 at the time of being connected to the access point. The DB generator 207 may also associate and store the communication sensitivity of the access point 201. The generated database 203 may be utilized by the local information determination system 208 to later match the IP information of the access point 201 and the regional information corresponding to the location information of the AP information collecting device 202. .

3 is a diagram illustrating an example of an operation of an AP information collecting device according to an embodiment of the present invention.

Referring to FIG. 3, the AP information collecting device 301 scans an access point 302 located in the vicinity of the AP information collecting device 301, and then identifies the AP information using the communication sensitivity. In this case, the AP information collecting device 301 may connect to the Internet through the access point 302. Then, the AP information collecting device 301 may transmit the location information (GPS information) of the AP information collecting device 301 to the local information determination system 304 by using an internet protocol such as TCP / IP through the Internet connection. . In this case, the location information of the AP information collecting device 301 means the location when the AP information collecting device 301 makes an Internet connection through the access point 302.

The AP information collecting device 301 may check the public IP of the access point 302 which is the source information according to the Internet protocol standard, and then transmit the AP information to the local information determination system 304.

Local information corresponding to IP information of the access point 302 may be more accurately determined through GPS information, which is location information of the AP information collecting device 301. If the IP information of the access point 302 is 129.192.91.29, the local information corresponding to the IP information is included in the latitude and location information included in the location information of the AP information collecting device 301 connected to the Internet through the access point 302. It will be highly relevant to local information corresponding to longitude. In order to ensure such relevance, the access point 302 may not be far from the AP information collecting device 301 according to the communication sensitivity. Therefore, it is possible to improve the accuracy of the local information by utilizing the location information of the device that collected the IP information rather than inferring the location information only by the IP information.

4 is a diagram illustrating a process of collecting IP information of an access point by an AP information collecting device according to an embodiment of the present invention.

Referring to FIG. 4, the AP information collecting device 401 may include a plurality of interfaces 402 to simultaneously connect to the plurality of access points 403. Even if there are a plurality of access points 403 identified through communication sensitivity in the vicinity, the acquisition time is long when only one connection is made, so that the AP information collecting device 401 can access the plurality of access points 403 at a time through the interface 402. ) To establish an Internet connection.

The information receiver 503 may receive the IP information of the access point and the location information of the AP information collecting device 501 from the AP information collecting device 501. In this case, the location information of the AP information collecting device 501 means a location when the AP information collecting device 501 connects to the Internet through an access point. The access point refers to an access point identified based on a communication sensitivity among a plurality of access points located around the AP information collecting device 501. The identified access point can be at least one. For example, the access point may indicate a communication sensitivity exceeding a preset reference value in the signal transmission process with the AP information collecting device 501 or belonging to the upper n of the plurality of access points.

The area information determiner 504 may determine the area information of the AP information collecting device 501 using the location information of the AP information collecting device 501. For example, the area information determiner 504 may determine an administrative area related to the location information of the AP information collecting device 501 as area information of the AP information collecting device 501. In detail, the area information determining unit 504 is based on an administrative area corresponding to the location information of the AP information collecting device 501 and an administrative area corresponding to at least one location information within a preset radius around the location information. The local information of the AP information collecting device 501 may be determined.

In this case, the area information refers to information used to determine which area the IP information of the access point corresponds to, and refers to geopolitical information that can be recognized by a person, such as a place name and an administrative district name. In addition, the IP information of the access point is likely to match the region information corresponding to the location information of the AP information collecting device 501 located in the vicinity of the access point and confirming the IP information.

A process of determining region information of the AP information collecting device 501 will be described in detail with reference to FIG. 6.

The information matching unit 505 may match area information of the AP information collecting device 501 and IP information of the access point. As described above, the region information of the AP information collecting device 501 is determined through the location information of the AP information collecting device 501. In addition, the access point is a device that the AP information collecting device 501 identifies through the communication sensitivity and makes an Internet connection. That is, by considering the communication sensitivity, the local information corresponding to the location information of the AP information collecting device 501 is highly related to the local information corresponding to the IP information of the access point by connecting to the Internet through the access point.

The matching between the IP information and the region information performed by the information matching unit 505 may include an operation of storing, managing, and updating information about the association between the IP and the region information. The information matching unit 505 may newly generate information on the IP-region information correlation, and when new location information or region information related to the same IP is confirmed, the IP based on the freshness and / or reliability of the information -The local information matching relationship can be updated. As described above, the strength of communication with the AP can be used as an indicator of reliability in this process.

The local information determination system 502 may provide various local services (coupon service, search service, advertisement service, etc.) to users located near the access point by using IP information matched with the local information.

6 is a diagram illustrating a process of determining region information according to an embodiment of the present invention.

Referring to FIG. 6, the area information determination system may determine area information of the AP information collecting device using location information of the AP information collecting device.

In FIG. 6, the point X 601 denotes location information of the AP information collecting device. At this time, the location information indicates GPS information, and the point X 601 indicates the location when the AP information collecting device connects to the access point over the Internet. Location information may be represented by simple numbers, while local information may refer to administrative districts, place names, and the like that can be identified by a person. The area information determination system may use a map service to determine area information of the AP information collecting device.

The area information determination system is configured to determine the area information of the AP information collecting device based on an administrative area corresponding to the location information of the AP information collecting device and an administrative area corresponding to at least one location information within a predetermined radius R from the location information. Can be determined. At this time, the area information determination system, at least one location information within a predetermined radius (R) from the location information of the AP information collection device is point A (602), point B (603), point C (604) and point D 605. For example, the at least one location information within a predetermined radius R from the location information of the AP information collecting device may be location information corresponding to east, west, north and south of the location information of the AP information collecting device. And, the preset radius can be adjusted according to the configuration of the system.

If the administrative area corresponding to point X 601 and the administrative area corresponding to point A 602, point B 603, point C 604, and point D 605 are all the same, the local information determination system May determine the administrative area corresponding to point X 601 as area information of the AP information collection device. If the administrative area corresponding to point X 601 is different from the administrative area corresponding to point A 602, point B 603, point C 604, and point D 605, the local information The determination system may not determine the administrative area corresponding to point X 601 as area information of the AP information collecting device. This example occurs when the point X 601 is located at the boundary of the administrative area, and if the administrative area corresponding to the point X 601 is determined as the area information of the AP information collecting device, the accuracy of the area information is reduced.
