DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The area information determination method according to an embodiment of the present invention may be performed by the area information determination system.

1 is a block diagram showing the configuration of a system for determining local information according to an embodiment of the present invention.

Referring to FIG. 1, the local information determining system 101 may include an information collecting unit 104, a local information setting unit 105, and a local information estimating unit 106.

The information collector 104 may collect basic data for setting or estimating area information of the IP address.

For example, the information collecting unit 104 may collect basic information indicating an association between the IP address and the specific region with the IP address. In addition, the information collecting unit 104 may obtain information indicating an association of a region with another IP address associated with the region information determination target IP address.

For example, input information from a user who is provided with a region-based service may be obtained by the information collecting unit 104 as basic information for determining a corresponding region for a certain IP address.

For example, if a user inputs local information of a user in order to check the weather of the area where the user provides the weather information service, the IP address assigned to the user terminal is matched with the local information input by the user. Can be logged.

The information collecting unit 104 may secure various kinds of information as basic information for determining the region information 103 related to the IP address in addition to the region information setting information directly from the user. For example, IP address information assigned to an access point (AP) that allows wireless Internet access is utilized as basic information for determining the region information 103 for the IP, together with the geographical location information associated with the access point. Can be.

When the separate AP information collecting device identifies the access point and accesses the Internet, the result of matching the GPS coordinates of the AP information collecting device or the administrative area (region information) corresponding thereto with the IP address of the access point may be collected. .

In this case, the information collecting unit 104 may collect basic information including an IP address allocated to the user terminal and input information of a user who receives the location-based service. That is, the input information input by the user in the location-based service may be said to be highly related to the region information 103 of the IP address allocated to the user terminal. Here, the input information of the user may be extracted through log information related to the location based service. This will be described in detail with reference to FIG. 2.

The information collecting unit 104 may collect the IP address assigned to the access point and the location information of the AP information collecting device connected to the wireless Internet through the access point. Here, the location information of the AP information collecting device may include an administrative area corresponding to the GPS coordinates or GPS information of the AP information collecting device. This will be described in detail with reference to FIG. 3.

The area information setting unit 105 may set the area information 103 of the IP address using the collected basic information.

If the collected basic information is input information of a user who receives a location-based service, the regional information setting unit 105 sets the regional information 103 of an IP address assigned to the user terminal based on the input information of the user. Can be. For example, the user's input information may be an administrative district name input by the user in the location-based service. Then, the area information 103 of the IP address may be set to the administrative area name input by the user.

And, if the collected basic information is the location information 103 of the AP information collecting device accessing the wireless Internet through the access point, the area information setting unit 105 is the area information 103 of the IP address assigned to the access point. Can be set. Here, the location information of the AP information collecting device may be converted to an administrative area of the same unit as GPS coordinates. The area information of the IP address assigned to the access point can then be set to the translated administrative area.

For example, the area information setting unit 105 may set the area information 103 of the IP address in consideration of the time-based weights related to the basic information. In this case, the hourly weight may include the freshness or validity period of the basic information. That is, if different basic information is collected for the same IP address, the local information setting unit 105 may set the local information 103 of the corresponding IP address using the most recent basic information. In addition, if the basic information has a valid period, the regional information setting unit 105 may set the regional information 103 of the corresponding IP address using the basic information that does not exceed the valid period.

For example, the area information setting unit 105 may set the area information 103 of the IP address in consideration of the reliability according to the type of the basic information. If the user's input information and the location information of the AP information collecting device that are input to the location-based service for the same IP address are collected as the basic information, the local information setting unit 105 may input the user's input information. Rather, the region information 103 of the IP address may be set by weighting the reliability of the location information of the AP information collecting device.

The area information estimator 106 may estimate area information of an IP address for which the area information 103 cannot be set. At this time, the IP address for which the area information 103 cannot be set has no or insufficient basic information indicating the relevance to a specific region, or there is a large number of basic information indicating the relevance with different regions for the same IP address. In this case, it means an IP address that is difficult to directly set the local information 103.

For example, the area information estimator 106 may estimate the area information 103 of the IP address by using the IP address group. At this time, the area information estimator 106 obtains the area information 103 of another IP address included in the IP address based on the IP address in which the area information 103 is set for the IP address group including the plurality of IP addresses. It can be estimated. That is, the area information 103 of the IP address may be estimated based on the IP address group. Here, the IP address group may be an IP subnet that is an IP allocation standard.

To this end, the area information estimator 106 may set a representative area for each IP address group, and estimate the set representative area as area information of an IP address included in the IP address group. That is, the area information 103 of the IP addresses belonging to the IP address group is equally estimated as the representative area set in the IP address group. At this time, the region information estimator 106 may set a representative region in an IP subnet to which the IP address to which region information is set belongs.

At this time, the area information estimator 106 may assign weights to the area information 103 of the IP address where the area information is already set in the IP address group in which the representative area is to be set. Then, the area information estimator 106 may set the representative area of the IP address group based on the assigned weight.

To this end, the area information estimator 106 may set a representative area through the following process. In this case, the representative region may be assigned to an IP subnet that is an IP address group, and a process of assigning weights to determine the representative region will be described in detail separately below.

The area information estimator 106 may assign the same identifier to IP addresses belonging to one IP subnet. In general, an Internet service provider (ISP) tends to distribute IP addresses in a process of locally distributing IP addresses to be allocated to user terminals. Thus, determining a representative region for an IP subnet, which is a distribution unit of IP addresses, can be a very powerful alternative in situations where basic information for determining region information 103 corresponding to a specific IP address is not sufficient.

In the DHCP (Dynamic Host Configuration Protocol) that ISPs use to assign IP addresses, IP subnets, which are distribution units of IP addresses, can be partitioned through IP MASK. In this case, a specific range of IP addresses (bands) may be divided into IP subnets consisting of consecutive IP addresses having a size of 1 / 2n of the range. The ISP may assign an IP address to the user terminal by assigning a divided IP subnet to a specific region. Therefore, representative region information of the corresponding IP subnet can be effectively estimated from region information related to some IP addresses belonging to the IP subnet which is an allocation unit of the IP address. Here, the part of the IP address means the IP address in which the IP address is set in the local information setting unit 105.

The area information estimator 106 may count the number of area information that is effectively matched with an IP address belonging to the IP subnet. When the same IP address is associated with the plurality of area information 103 in the IP subnet, the area information estimator 106 may determine that the corresponding IP address does not effectively match specific area information. Then, the region information estimator 106 may exclude the information related to the IP address in the process of determining the representative region of the IP subnet. For example, when a log in which a user who accesses a single IP address inquires about weather in several regions within a predetermined time is checked, one region information that is validly matched to the IP address cannot be specified. In this case, the region information of the IP address related to the log inquiring the weather of various regions can be excluded to determine the representative region of the IP subnet.

Thereafter, the region information estimator 106 may set the region information counted most among the region information matched to the IP address for each IP subnet as the representative region of the corresponding IP subnet. For example, if an IP subnet includes IP addresses matched with region X, region Y, and region Z region, and among them, Z region is included the most, the representative region of the corresponding IP subnet may be set as Z region.

However, the most counted area information does not always have to be determined as the representative area of the IP subnet. The representative region of the IP subnet can be set by considering the reliability of region information related to individual IP addresses belonging to the IP subnet as a weight. At this time, the reliability of the area information may be determined according to the type of the basic information that the freshness of the area information and / or the relationship between the IP address and the area information is established.

Meanwhile, in order to set a representative region having higher reliability, the region information estimator 106 may divide the corresponding IP subnet into a plurality of subnets again and set the representative regions for the divided subnets, respectively. In detail, the area information estimator 106 may divide the data into other subnets having a size of 1 / 2n of the corresponding IP subnet. The repartitioning of IP subnets may be determined to take into account the distribution of regional information set to IP addresses belonging to a specific IP subnet. The representative region information of an IP subnet determined through the above process may be used as basic data for determining the representative region of the upper IP subnet (group) including the corresponding IP subnet.

The region information estimator 106 may assign a weight to the IP subnet in order to set a representative region related to the IP subnet.

For example, the region information estimator 106 may assign a weight based on the number of IP addresses included in the IP subnet in which the representative region is to be determined. That is, the representative area set in the IP subnet may be determined whether the probability of being a downtown area or a suburban area is high depending on the number of IP addresses included in the IP subnet. Since the urban area has a large population, the number of IP addresses included in the IP subnet of the urban area is set larger than the number of IP addresses included in the IP subnet of the suburban area. That is, when the IP subnet including a lot of IP addresses includes the IP address associated with the downtown area and the suburban area, if the other conditions are the same, the IP subnet may be further weighted to the downtown area.

Therefore, the area information estimator 106 may allocate the weighted score of the downtown area to the corresponding IP subnet as the number of IP addresses included in the IP subnet that is the IP allocation criterion of the IP address increases. In addition, the area information estimator 106 may allocate a weight score of the suburban area as the number of IP addresses included in the IP subnet of the IP address decreases. Regional weights are described in detail in FIG. 4.

As another example, the region information estimator 106 may reflect the latestness of the information considered in setting and estimating the region information for the IP address / IP subnet as a weight. For example, if the region information set for the same IP address was previously changed from region A to the current region B, the region information estimator 106 sets the representative region of the IP subnet including the IP address. Rather than the association with region A for an address, a higher weight may be given to the association between the IP address and region B. In some cases, the association between the IP and Region A may be completely excluded. Such time-weighted weights can also be applied in the process of individually setting the region information of the IP address. Hourly weights are described in detail in FIG. 5.

As another example, the area information estimator 106 may analyze the relationship between representative regions of the IP address group and perform a sum operation between the IP address groups. Specifically, the summation calculation process for the IP address group will be described in detail with reference to FIG. 6.

In conclusion, the region information estimator 106 may estimate region information of another IP address belonging to the IP group based on region information of the IP address in which region information is set in the IP address group to which the plurality of IP addresses belong.

For example, the region information of another IP address belonging to an IP address group (IP subnet) that is estimated to have been distributed in the same region for an IP address for which the region information was not set directly in the region setting unit 105 is displayed. Can be used for estimation. If all of the IP addresses except one of the IP addresses belonging to one IP subnet are related to the same region, it can be estimated that the one IP address is also assigned to the same region. In addition, when IP addresses belonging to one IP subnet match multiple regions, the IP subnet can be subdivided to have a sufficiently high estimated reliability, and higher than the region information matched to each of the divided IP subnets. Area information with reliability may be estimated as area information of an IP address that cannot be directly set in the IP subnet.

2 is a diagram illustrating an example of collecting an IP address and basic information through a location based service according to an embodiment of the present invention.

Referring to Action 1, the local information determination system may collect basic information including an IP address assigned to a user terminal using the web service 201 and input information of the user for the web service 201. In other words, the input information input by the user in the location-based service is highly related to the regional information of the IP address allocated to the user terminal. At this time, the area information may be identified by the area code. Here, the user's input information may be extracted through log information 202 related to the location based service.

For example, when a user inputs local information through the web service 201, an IP address allocated to the user terminal may be matched with local information which is input information input by the user. In this case, the region information input by the user may be used as basic information for determining region information of the IP address. In the present invention, the web service 201 is related to a location-based service, and may include all services that provide information related to a region when a user inputs a region such as weather, restaurant information, and traffic.

Referring to FIG. 2, the information input by the user through the web service 201 and the IP address assigned to the user terminal of the user may be collected through the web log 202. Referring to the web log 202, it can be seen that a user connected to an IP address of 157.56.48.2 receives a service related to area information corresponding to the area information code 02135550.

That is, the local information determination system may collect basic information including an IP address assigned to the user terminal and input information of a user who receives a location based service. The collected basic information can then be used to determine local information of the IP address.

Then, in Action 3, the area information code may be converted into area information indicating an administrative area that can be identified by a person. Then, regional information may be set for each IP address. For example, if a user connected to the IP address 157.56.48.2 checks the weather information of the neighborhood corresponding to the area code 02135550, the area information corresponding to the area code 02135550 is set for the IP address 157.56.48.2. Can be.

3 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 local information determination system may collect IP addresses matched with local information in a manner other than the web service 201. For example, a vehicle-mounted IP address collection system connects to the Internet through an access point located nearby to collect the access point's IP address, and local information corresponding to the access point's IP address and GPS information of the IP address collection system. Can be matched. At this time, the access point may exist at a location where the association between the location information of the IP address collection system and the IP address of the access point can be guaranteed.

The AP information collecting device 300 may collect IP addresses of access points (APs) 301 ˜ 303 located nearby. At this time, the AP information collection device 300 may attempt to connect to the access point and transmit the public IP address of the access point to the local information determination system. The access points 301 ˜ 303 may be access points that do not have a separate security setting, but in some cases, information on access points with security may be collected.

The AP information collecting device 300 establishes an Internet connection through the access points 301 to 303, and the AP information collecting device 300 connects to each of the access points 301 to 303 via the GPS satellite 304. You can check the location information. That is, the AP information collecting device 300 secures an internet connection through the access points 301 to 303, thereby enabling the use of an IP address assigned to the internet connected access points 301 to 303.

The AP information collecting device 300 may transmit the IP addresses of the access points 301 ˜ 303 and the location information of the AP information collecting device 300 to the local information determining system 105. At this time, the location information of the AP information collecting device 300 is used as basic information for determining the area information of the IP address of the access point (301 ~ 303). Specifically, the area information determination system 105 may determine the area information, which is an administrative area corresponding to the IP address, by using the received IP addresses of the access points 301 to 303 and the location information of the AP information collecting device 300. have.

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 300.

In the present invention, the protocol utilized for the communication between each access point and the AP information collecting device 300 is not limited to a specific one, any protocol for providing short-range wireless communication may be utilized for the implementation of the present invention.

4 is a diagram illustrating a process of assigning a weight for each region according to an embodiment of the present invention.

The region information determination system described with reference to FIG. 4 may set a representative region in an IP address group including a plurality of IP addresses using regional weights. The local information determination system can identify the IP address according to the IP subnet. An IP subnet is a group of IP addresses that includes at least one IP address and means IP allocation criteria. IP addresses can be assigned from 1 to 256. If the number of IPs that make up an IP subnet is set to 32, the total IP subnet is eight.

The area information determination system may count the number of area information set in the IP address for each IP subnet. In this case, when a plurality of region information is matched to the same IP in the IP subnet, the region information determination system may remove the corresponding IP address from the IP subnet and count the number of region information set in the IP address. That is, since an IP address that can be derived as being related to a plurality of region informations will be difficult to determine as being associated with specific region information, the region information determination system may determine the representative region corresponding to the IP subnet. By excluding the accuracy of the representative area corresponding to the IP subnet can be improved.

Then, the representative region may be set for each IP subnet according to the number of region information matched with the IP address. For example, if there are four IP addresses corresponding to Region A and two IP addresses corresponding to Region B in an IP subnet that assigns IP addresses of 1 to 31, the IP subnets to which IP addresses from 1 to 31 are assigned. The representative area may be set as area A. In some cases, an upper region including region A and region B may be identified as a region corresponding to the corresponding subnet.

At this time, the region information determination system may assign a weight for each region to the IP subnet based on the number of IP addresses included in the IP subnet which is an IP allocation criterion. The minimum number of IPs included in the IP subnet may vary based on the size of the region to which the IP band is allocated. When assigning IP addresses to local equipment, ISPs tend to allocate 256 or 128 IP subnets in urban areas with high demand for IP addresses. Smaller suburbs tend to allocate IP subnets with 64 or 32 IP addresses.

Therefore, when the number of IP addresses constituting the IP subnet, which is the IP allocation standard, is 256 or 128, the weighted score of the urban area may be assigned to the IP subnet. In addition, when the number of IP addresses constituting the IP subnet as the IP allocation standard is 32 or 64, the weighted score of the suburban area may be allocated to the IP subnet. By applying weights for each region, the representative regions of the IP subnets are divided into downtown and suburbs, so that representative regions can be accurately set for each IP subnet.

5 is a diagram illustrating a process of allocating weights according to an embodiment of the present invention.

Referring to FIG. 5, a history of an IP address in which region information is set according to time in one IP subnet is illustrated. Referring to FIG. 5, it can be seen that, on October 15, local information such as "Sehyeon 1-dong, Bundang-gu, Seongnam-si" is set to the IP address 222.122.12.29. In addition, on November 1, local information such as "Seong 1-dong, Bundang-gu, Seongnam-si" is set to IP address 222. 222.222.20, and regional information such as "Sea 2-dong, Bundang-gu, Seongnam-si" is set to IP address 222.22.222.16. Able to know. In addition, it is assumed that the most recent IP address 222. 222.222.22 in which local information, such as "Yatap-dong, Bundang-gu, Seongnam-si," was added on November 3rd.

It can be inferred that the local information corresponding to the corresponding IP subnet has been changed to "Yatap-dong, Bundang-gu, Seongnam-si." In other words, it can be expected that the IP address associated with Seohyeon 1-dong or Sunae 2-dong, which is local information, is assigned to the IP subnet corresponding to 1 to 31, and recently changed to Yatap-dong. Then, the local information determination system may assign a weight for each region to an IP address corresponding to Yatap-dong, Bundang-gu, Seongnam-si than 1-dong or Sunae 2-dong, Bundang-gu, Seongnam-si in the corresponding IP subnet. Also, in some cases, matching may be performed between IP address-region information using the district-specific region name, which is a higher administrative region, by varying the level of region information corresponding to the subnet.

As a result, the regional information determination system may assign an hourly weight to the IP address based on the freshness of the regional information matched to the IP address. In detail, when the IP information corresponding to other area information not included in the IP subnet is recently inputted, the area information determination system may assign a high time weight to the recently inputted IP address. Can be. Then, when recounting the region information matched to the IP address, the representative region set in the IP subnet may be changed.

Through this process, when determining the final representative region related to the IP subnet, it is possible to improve the accuracy of the representative region set in the IP subnet by preparing for the change in the IP band allocated to the user.

FIG. 6 is a diagram illustrating a process of setting a representative region by summing operation on an IP address group according to an embodiment of the present invention.

Referring to FIG. 6, the region information of the greatest number of times per IP subnet may be set as a representative region of the IP subnet. For example, it is assumed that a score calculated as a result of applying a weight in an IP subnet including IP addresses of 1 to 31 is 33 having the highest score. Then, the IP subnet is set to "representative area 1 Seohyeon 1-dong, Bundang-gu, Seongnam-si, Gyeonggi-do." Through this process, the local information "1 dong, Seohyeon 1-dong, Bundang-gu, Seongnam-si, Gyeonggi-do" is set as the representative region in the IP subnet of 1-31, 64-91, 128-159 and 160-191 among the eight IP subnets.

At this time, the IP subnet is divided into 1/2 units, and one IP subnet corresponds to one region. If the adjacent IP subnets are also adjacent to the actual region. Therefore, even if the regions are aggregated and analyzed by adding the IP subnets (1 to 31) and the IP subnets (32 to 63) that are adjacent to each other, the most information of the region may be determined as "1, Seohyeon 1-dong, Bundang-gu, Seongnam-si, Gyeonggi-do". have.

If it is certain that the first IP subnet (1-31), the second IP subnet (32-63), and the fourth IP subnet (96-127) are assigned to the same region X, the third IP subnet (64-95) is the same. Naturally assigned to area X. Thus, according to the present invention, the area information determination system can improve the accuracy of the representative area set in the IP subnet by stepwise summing the blocks corresponding to the IP subnet.

As shown in FIG. 6, when the blocks corresponding to the IP subnets are gradually added and calculated, the most area information in the added blocks is determined as "1 dong, Seohyeon-dong, Bundang-gu, Seongnam-si, Gyeonggi-do." Then, the representative area of the IP subnet involved in the summation operation may be set to the area information "Seohyeon 1-dong, Bundang-gu, Seongnam-si, Gyeonggi-do".

Meanwhile, in order to set a representative region having higher reliability, the region information determination system may divide the corresponding IP subnet into another subnet having a size of 2n, and set the representative region for each of the divided subnets. have. Repartitioning of IP subnets may be determined to take into account the distribution of regional information set for IP addresses belonging to a particular subnet.

As a result, the region information determination system may set a representative region for each IP address group, and estimate the set representative region as region information of an IP address included in the IP address group. At this time, the region information determination system may set a representative region in the IP subnet to which the IP address to which the region information is set belongs.

7 is a flowchart illustrating a method for determining region information according to an embodiment of the present invention.

The area information determination system may collect an IP address and basic information indicating an association between the IP address and a specific area (S701).

For example, the local information determination system may collect basic information including an IP address assigned to a user terminal and input information of a user who receives a location based service. In this case, the user input information may be extracted through log information related to the location-based service.

As another example, the local information determining system may collect an IP address assigned to an access point and location information of an AP information collecting device connected to the wireless Internet through the access point. In this case, the location information of the AP information collecting device may include a GPS coordinate of the AP information collecting device or an administrative area corresponding to the GPS information.

The area information determination system may set area information of the IP address using the basic information (S702). For example, the local information determination system may set local information of an IP address using basic information including an IP address allocated to a user terminal and input information of a user who receives a location-based service. The area information determination system may set the area information of the IP address using the basic information including the IP address assigned to the access point and the location information of the AP information collecting device connected to the wireless Internet through the access point.

In one example, the regional information determination system may set the regional information of the IP address in consideration of the time-based weights associated with the basic information. In this case, the hourly weight may include the freshness or validity period of the basic information. As another example, the area information determination system may set the area information of the IP address in consideration of reliability according to the type of basic information.

The area information determination system may estimate area information of an IP address for which area information cannot be set using the IP address group (S703).

For example, the region information determination system may estimate region information of another IP address included in the IP address group based on the IP address in which the region information is set for the IP address group including the plurality of IP addresses. At this time, the regional information determination system may set a representative region for each IP address group, and estimate the representative region as regional information of an IP address included in the IP address group. Here, when the region information of the IP address included in the IP address group is associated with a plurality of regions, the region information determination system may set a representative region by dividing the IP address.

In order to set the representative region, the regional information determination system may assign weights to the region information of the IP address where the region information is set in the IP address group, and set the representative region of the IP address group by using the weight. At this time, the regional information determination system may set the representative region for the IP address group by using the up-to-date information on the regional information of the IP address included in the IP address group or the weight for each region according to the number of IP addresses.

On the other hand, in the above description about the determination of the regional information about the IP subnet and individual IP address may be understood as a supplement to each other. This is obvious in that the IP address is an extreme example of an IP subnet with only one entry.

For matters not described in FIG. 7, the description of FIGS. 1 to 6 may be referred to.
