The indoor location based service providing system according to an embodiment of the present invention shown in FIG. 1 may include a wireless local area network (LAN) 100, a location registration terminal 200, a server 300, and a customer terminal 400. The present invention relates to a method for providing an indoor location based service using a wireless LAN (100) and a system for providing an indoor location based service. According to an embodiment of the present invention, a store is located inside a building, and a wireless LAN (or access point) 100 is installed in the store. A specific application is installed in the terminal (hereinafter referred to as the location registration terminal 200) to register the location of the store. One wireless LAN may be installed in the inside of the store, or a plurality of wireless LANs may be installed with different MAC addresses according to the size of the store.

Hereinafter, the location registration procedure of a store located in a building will be described. 2 and 3, the location registration terminal 200 is provided with a first application unit 210 for providing GPS information and map information of stores. At this time, the first application unit 210 means a configuration including an application installed in the terminal. The first application unit 210 generates GPS information and map information of a store located indoors using a positioning device (GPS, for example) provided in the terminal 200, and transmits the generated GPS information and map information to the information transmission unit 250.

The store information acquiring unit 220 acquires the name of the building in which the store is located, the store name, the store number, and the store information for the business type. The store information can be obtained by being transferred from the terminal device (not shown) installed in the store to the location registration terminal 200. Alternatively, as shown in FIG. 3, after the registrant having the location registration terminal 200 directly visits the store, the first application unit 210 may be executed to input the store information. The store information acquiring unit 220 delivers the acquired store information to the information delivering unit 250.

 The photographing unit 220 photographs an indoor photograph of the store. The photographing of the indoor photograph can be automatically performed together with the acquisition of the store information. Referring to FIG. 4, the indoor photograph information may include the latitude and longitude values of the photographing place matched with each other. In addition, the indoor photograph information may include a matching date and time of the indoor photograph. The values described in the indoor photograph information may be tagged and transmitted to the information transmitting unit 250. [

The first wireless LAN information acquisition unit 240 acquires information on the wireless LAN 100 installed in the store. In one embodiment, the first wireless LAN information obtaining unit 240 may obtain the SSID, the MAC address, and the signal strength (RISS) allocated to the MAC address of the Wi-Fi access point installed in the store. Hereinafter, the SSID, the MAC address, and the signal strength of the access point acquired by the location registration terminal 200 are referred to as first wireless LAN information.

In the present invention, the signal strength received from the access point is represented by an absolute value, and the larger the absolute value, the more intense the signal strength is. The circles in the dashed lines in Figs. 5-7 illustrate the coverage of the access point. That is, when the coverage is overlapped, the access point of another store can be searched. For example, referring to FIG. 6, AP1, AP2, AP3, AP4, and AP5 are all searched when searching for an access point in AP1 store. In addition, it is assumed that the range in which the circles of the dotted lines are overlapped is that the coverage of the access points of the other stores are overlapped, and that the wider the overlapping area, the stronger the signal strength is.

Referring to FIG. 5, as a first embodiment, one access point is searched in the first store (a single access point). In this case, one access point information is included as follows. The access point information is the first wireless LAN information, and the first wireless LAN information is displayed in the order of SSID (Mac address, RISS). However, in the first embodiment, the first wireless LAN information can be included in the first wireless LAN information only when the measured signal strength value is equal to or higher than the reference value.

SSID (Mac address, RISS) AP1 (192.168.43.199,140)

 Hereinafter, a case in which a plurality of AP signals are searched for in the same burial location in the present invention will be described. Referring to FIG. 6, as a second embodiment, a total of five access points are searched in the first store. In this case, the first wireless LAN information may include five pieces of access point information as follows. At this time, the location registration terminal 200 can select AP1 information having the largest measured signal strength (RISS) as the wireless LAN information. That is, AP1 (192.168.43.199,140) may be selected as the first wireless LAN information to be transmitted to the server 300 and the information may be transmitted to the information delivery unit 250. [ However, at this time, it can be included in the first wireless LAN information only when the signal strength is the highest value above the reference value.

SSID (Mac address, RISS) AP1 (192.168.43.199, 140), AP2 (194.169.43.1990.45), AP3 (193.168.53.199,60), AP4 (202.167.42.181, 64), AP5 (192.158.43.199, 59)

Referring to FIG. 7, access points of AP1 to AP5 are searched in the first store as a third embodiment. At this time, the coverage of AP6 is not searched in the first store area (appearance frequency is 0). According to the third embodiment, the first wireless LAN information obtained in the first store, which is the measurement target store, may include a plurality of access point information as follows. At this time, the location registration terminal 200 may measure the first wireless LAN information several times in the same store, and may select the first wireless LAN information to be transmitted to the server 300.

Referring to Table 3, a total of five access pointers can be searched and measured within the same store. At this time, the first wireless LAN information transmitted to the information transferring unit 350 may be selected as follows. The total measured access point is selected as a candidate. Since a total of 5 measurements were made from AP1 to AP5 in the total of 5 measurements, AP1 to AP5 are candidates for AP. Next, the total appearance frequency of the access point candidate is calculated. The appearance frequency is a percentage value obtained by dividing the total number of appearances of the access point by the number of times of measurement. AP1 and AP2 have 5 appearances, AP3 is 4, AP4 is 2, and AP5 is 3. In this case, the appearance frequencies of AP1 to AP5 are calculated as follows.

AP1: 5/5 * 100 = 100. AP2: 5/5 * 100 = 100, AP3: 4/5 * 100 = 80, AP4: 2/5 * 100 = 40, AP5: 3/5 * 100 = 60

If the calculated appearance frequency is less than a predetermined value, the MAC address and signal strength measured at the access point having a low appearance frequency are treated as noise. If the frequency of appearance is 60 or more, AP1, AP2, AP3, and AP5 can be selected as access points of the first wireless LAN information. Next, the average value of the signal strength assigned to the selected access point is calculated. The average value of the signal intensities is a value obtained by dividing the sum of the total signal intensities of the respective access points by the appearance frequency. Thus, the average signal strength of AP1 is 140.4, AP2 is 138.2, AP3 is 60.25. AP5 is calculated as 59. In this case, the first wireless LAN information may be one in which the average signal strength value is matched to the MAC address of the selected access point. Therefore, in the above case, the first wireless LAN information may be AP1 (192.168.43.199, 140.4), AP2 (194.169.43.199.18.2), AP3 (193.168.53.199, 60.25), AP4 (192.158.43.199, 59) .

 AP1: (140 + 140 + 138 + 141 + 143) /5=140.4

 AP2: (145 + 140 + 141 + 135 + 130) /5=138.2

 AP3: (60 + 63 + 58 + 60) /4=60.25

 AP5: (59 + 59 + 59) / 3 = 59

Describing the fourth embodiment with reference to Table 3, the total measured access point is selected as a candidate. Since AP1 ~ AP5 are searched and measured in the total of 5 measurements, the access point candidates are AP1 ~ AP5. The access point candidates are AP1 to AP5. Next, the total appearance frequency of the access point candidate is calculated. The appearance frequency is a percentage value obtained by dividing the total number of appearances of the access point by the number of times of measurement. AP1 and AP2 have 5 appearances, AP3 is 4, AP4 is 2, and AP5 is 3. In this case, the appearance frequencies of AP1 to AP5 are calculated as follows.

AP1: 5/5 * 100 = 100. AP2: 5/5 * 100 = 100, AP3: 4/5 * 100 = 80, AP4: 2/5 * 100 = 40, AP5: 3/5 * 100 = 60

If the calculated appearance frequency is less than a predetermined value, the MAC address and signal strength measured at the access point having a low appearance frequency are treated as noise. If the frequency of appearance is 60 or more, AP1, AP2, AP3, and AP5 can be selected as access points of the first wireless LAN information. Next, the average value of the signal strength assigned to the selected access point is calculated. The average value of the signal intensities is a value obtained by dividing the sum of the total signal intensities of the respective access points by the appearance frequency. Thus, the average signal strength of AP1 is 140.4, AP2 is 138.2, AP3 is 60.25. AP5 is calculated as 59.

 AP1: (140 + 140 + 138 + 141 + 143) /5=140.4

 AP2: (145 + 140 + 141 + 135 + 130) /5=138.2

 AP3: (60 + 63 + 58 + 60) /4=60.25

 AP5: (59 + 59 + 59) / 3 = 59

Next, AP1, which is the largest value among the average values calculated as an example, is selected. This AP1 can be selected as the reference access pointer, and the information of AP1 can be set as the first wireless LAN information. Other examples of reference access pointer selection may be selected as follows. That is, the difference between the average value of each access point and the average value of AP1 is calculated.

The average signal strength difference between AP2 and AP1 is 2.2.

The average signal strength difference between AP3 and AP1 is 80.15.

The average signal strength difference between AP5 and AP1 is 81.4.

The access point within the error range can be selected as the reference access point when the difference value is within the predetermined error range. If the error range is set to 5, AP2 can be selected as the reference access point. As a result, the first wireless LAN information is an average value matched with the MAC addresses of AP1 and AP2 (192.168.43.199, 140.4) (194. 169.43.199.138.2). The remaining AP3 and AP5 are treated as noise.

Referring to FIG. 2, the first wireless LAN information acquisition unit 240 transmits the first wireless LAN information acquired in the first through fourth embodiments to the information transfer unit 250. FIG. The information transmission unit 250 may transmit the map information, the store information, the first wireless LAN information, and the indoor photograph information including the received latitude and longitude values to the server 300. Here, the indoor photograph information may include a room photograph, a latitude and longitude value of a place where the room photograph is taken, and a date and time when the room photograph was taken.

The information input unit 301 of FIG. 8 receives map information, store information, first wireless LAN information, and indoor photograph information including latitude and longitude values from the terminal. The information classification unit 302 receives the information from the information input unit 301. The received information can be classified into the first to seventh information and transmitted to the location registration determination unit 303 and the information matching unit 304.

The first information is an indoor photograph of a store, which is image information that does not include a texture. The second information is latitude and longitude values of the store (hereinafter referred to as first latitude and longitude values) included in the GPS information of the store received from the first application. The third information is a latitude and a longitude value of the place where the indoor shop photograph was taken (hereinafter referred to as a second latitude and longitude value). The fourth information is the MAC address and signal strength information of the access point as the first wireless LAN information. The fifth information is map information of the store acquired from the first application unit 210. [ The sixth information includes at least one of the name of the building, the name of the building, the number of floors, the name of the building in which the business type is located, and the like. And the seventh information is the date and time at which the indoor photograph was taken.

Referring to FIG. 9, the first location registration determination unit 303a determines whether the indoor photograph, which is the first information, is photographed indoors. When it is determined that the indoor photograph is photographed outdoors, a procedure for re-photographing the indoor photograph is performed. That is, by transmitting a re-registration signal to the location registration terminal, the photographing unit 230 of the location registration terminal can photograph the indoor photograph again. If it is determined that the transferred photograph is a photograph taken indoors, the indoor photograph may be registered in the server 300 by transmitting the indoor photograph to the information matching unit 304. The first location registration determination unit 303a extracts the feature points of the photographs transmitted from the information classification unit 302 using the tensor flow and determines whether the photographs are photographed indoors based on the extracted feature points do. In one embodiment, the first location registration determination unit 303a extracts a portion corresponding to the floor of the room from the indoor photograph. The first location registration determination unit 303a determines whether the photographed image based on the extracted floor image is photographed indoors. The first location registration determination unit 331 determines that the extracted floor photo has an asphalt texture and determines that it is photographed outdoors so that a first re-registration signal is generated (Re-registration procedure is performed). The first location registration determination unit 303a can determine that the extracted floor photograph is photographed indoors if it is determined that the extracted floor photograph has a marble texture. In this case, the indoor photograph image information included in the information classification unit 302 may be transmitted to the information matching unit 304. In the present invention, the floor information is taken as an example for the sake of understanding, but various information can be classified and defined for indoor and outdoor judgment.

The second location registration determination unit 303b may receive the first latitude and longitude values, which are the second information, and the second latitude and longitude values, which are the third information, from the information classifying unit 302. The second location registration determination unit 303b calculates the difference between the received first latitude and longitude values and the second latitude and longitude values. Then, it is determined whether or not the difference between the first latitude and longitude values and the second latitude and longitude values is within a predetermined error range. The second location registration determination unit 303b determines that the indoor photograph is taken at a location where the actual store is located and transmits the second latitude and longitude values to the information matching unit 304 . On the contrary, if it is determined that the second location registration determination unit 303b is out of the predetermined error range, it is determined that the indoor photograph was photographed at a place other than the one photographed at the store. Thus, the second location registration determination unit 303b generates a second re-registration signal to re-photograph the indoor photograph at the location where the actual store is located. That is, when the first latitude and longitude values are different from the second latitude and longitude values and the second re-registration signal is generated, it means that the photographed indoor photograph is not taken at the place where the actual store is located. It is possible to more accurately judge whether or not the person is authentic. Here, the difference between the first latitude and longitude values and the second latitude and longitude values means a difference between latitude and longitude values.

Hereinafter, with reference to FIG. 10, a description will be made of a method for preventing a registration error of each first wireless LAN information acquired at two stores located at different locations. The third location registration determination unit 303c receives from the information matching unit 304 the first latitude and longitude values of the first store and first latitude and longitude values of the second store, The MAC address of the access point obtained in the second store and the MAC address of the access point acquired in the second store. The third location registration determination unit 303c may transmit the re-registration signal to the terminal 200 or may register the first wireless LAN information in the server 300 via the following steps.

The third location registration determination unit 303c first determines whether the MAC addresses of the access points acquired in the first store and the second store are the same. That is, referring to FIG. 10, the MAC address of the access point of the first store and the MAC address of the access point of the second store are the same. Next, the third location registration determination unit 303c determines whether the locations of the first store and the second store have latitude or longitude values deviating from a predetermined error range. For example, the error range of any one of the latitude and longitude values can be preset to 0.01. The hardness values are the same among stores but the latitude values are different from each other by 0.3, so they deviate from the preset error range. When the positions of the first store and the second store having the same MAC address have a latitude or longitude value deviating from a predetermined error range, the third location registration determination unit 303c determines whether the first store or the second store 1 wireless LAN information is an error. Then, the third location registration determination unit 303c generates a third re-registration signal to perform a re-registration procedure. Accordingly, the first wireless LAN information must be acquired again. Therefore, the present invention has an advantage of preventing the registration error of the same MAC address despite the different stores.

The third location registration determination unit 303c determines whether the MAC address of the access point acquired in the first store and the access point acquired in the second store are not the same or the latitude and longitude of the first store and the second store The first wireless LAN information in the first store and the first wireless LAN information in the second store, which are the fourth information, may be stored in the first store, To the information matching unit 304.

The fourth location registration determination unit 303d of the present invention determines the location information of the first store and the store information of the second store, which are the sixth information, from the information matching unit 304, And the MAC address of the access point measured at the second store. In the case where the first store and the second store are located on different layers in the same building, registration error of the same MAC address can not be prevented only by the above-described latitude and longitude values. If it is determined that the number of buildings in which the first store and the second store are located in the location registration terminal 200 is out of a predetermined range and that the first and second stores have the same MAC address, the MAC address is a registration error .

The fourth location registration determination unit 303d acquires the number of floors of the first store and the second store from the store information of the first store and the store information of the second store received. Since the store information includes the name of the building in which the first store and the second store are located, the mutual name of the store, the number of floors, and the type of business, the first and second store information indicates the number of the buildings in which the first store and the second store are located Can be obtained.

Then, it is judged whether or not the first store and the second store are more than the difference in the number of the layers within the predetermined range. If the difference in the number of storeys between the first store and the second store is greater than or equal to a preset number of storages, the MAC address of the first store and the MAC address of the second store are compared and the MAC address measured at the first store and the MAC address of the second store It is determined whether the measured MAC address is the same. If it has the same MAC address, it can generate a fourth re-registration signal for measuring the first wireless LAN information of the first store and the second store again and transmit it to the location registration terminal 200. Therefore, the present invention has an advantage of preventing the registration error of the access point. The fourth location registration determination unit 303d determines that the difference in the number of floors between the first store and the second store is out of a predetermined range (that is, the different stores are located in different layers) And generates a fourth re-registration signal requesting re-registration if the second store has the same MAC address. Accordingly, the wireless LAN information of the first store and the second store can be measured again.

As described above, the server 300 may determine that the indoor photograph is photographed outdoors, or that the room where the indoor photograph was photographed does not match the actual store, or the same Mac address Or when the MAC addresses of different stores located at different levels in the same building are equal to each other, the location registration information (information for re-measuring the wireless LAN information or re-photographing the indoor photographs) is generated again Registration signal to the location registration terminal, and does not store the location registration information. On the contrary, when the first to fourth re-registration signals are not generated, the location registration information is stored in the store information DB unit.

Referring to FIG. 11, the information matching unit 304 receives indoor photographs, second latitude and longitude values transmitted from the information classifying unit 302, (Location registration information) including the first wireless LAN information, the map information, the store information, the date and time information of the indoor photographing, and transmits the store location information to the store information DB unit 305. The store information DB unit 305 may store the delivered store positioning information.

The above description has described a method of registering the location registration information indicating each store in the server 300 using the location registration terminal 200. Hereinafter, the location registration information of the store registered in the server is used We will show you how to check if a customer has visited a real shop.

Hereinafter, the customer regards the customer terminal 400 as a person who visits the store. The second application unit 410 generates a second wireless LAN acquisition signal for acquiring wireless LAN information of the store (hereinafter, referred to as second wireless LAN information) when the customer visits the store previously registered, 2 wireless LAN information acquisition unit 420. [ In one embodiment, the second application may generate a second WLAN acquisition signal when the SDK is installed and the customer terminal visits a place where the customer terminal is already registered.

The second wireless LAN information acquisition unit 420 acquires information on a wireless LAN installed in the store in response to the second wireless LAN acquisition signal. In an embodiment, the second wireless LAN information acquisition unit 420 may acquire the SSID, the MAC address of the Wi-Fi access point installed in the store, and the signal strength (RISS) received from the access point. Hereinafter, the MAC address and the signal strength of the Wi-Fi access point acquired by the second wireless LAN information acquisition unit 410 are referred to as second wireless LAN information.

Also, the second wireless LAN information acquisition unit 410 may acquire the second wireless LAN information acquisition time, which is the time when the second wireless LAN information is acquired, and the customer terminal information, 30 seconds) to the second wireless LAN information input unit 306. Here, the customer terminal information may include at least one of an encrypted serial number, IMEI, and OS version of the customer terminal.

The second wireless LAN information input unit 306 of the present invention can receive the second wireless LAN information, the second wireless LAN information acquisition time, and the customer terminal information from the second wireless LAN information acquisition unit 420. In addition, the second wireless LAN information input unit 306 may include at least one of the received second wireless LAN information, the second wireless LAN information acquisition time, and the customer terminal information as a check-in determination unit 307, a visit determination unit 308, To the path calculation unit 309.

The check-in determination unit 307 of the present invention receives the second wireless LAN information from the second wireless LAN information input unit 306 and transmits the store positioning information including the first wireless LAN information from the store information DB unit 305 Can receive. Then, the check-in determination unit 307 may determine whether the first wireless LAN information and the second wireless LAN information are matched. If it is determined that the first wireless LAN information and the second wireless LAN information are matched, it can be determined that the customer has checked in the store. Here, the fact that the wireless LAN information is matched includes not only the ID of the AP (SSID as an example), the MAC address and the signal strength, but also belongs to a certain error range.

Hereinafter, it is assumed that the MAC address matching rate of the first wireless LAN information and the second wireless LAN information is set to 60% and the signal intensity error is set to 10. [ 13, the first wireless LAN information is AP1, AP2, AP3, and AP5, and the second wireless LAN information is AP1, AP2, AP3, and AP8. In this case, the three MAC addresses do not coincide with each other, and only the AP3 coincides with each other. Therefore, the MAC address matching rate is smaller than the predetermined matching rate of 60%. Accordingly, the check-in determination unit 307 determines that the customer has not checked in the store.

14, the first wireless LAN information is AP1, AP2, AP3, and AP5, and the MAC address and signal strength of the second wireless LAN information are AP1, AP2, AP3, and AP9, respectively. In this case, since the MAC addresses of the first wireless LAN information and the second wireless LAN information are all the same, the matching rate of the MAC address is 100%. However, the signal intensities assigned to the second and third MAC addresses are 138.2 and 60.25, respectively, for the first WLAN information, and 20 and 40 for the second WLAN information, respectively. Therefore, the check-in determination unit 307 determines that the customer has not checked in the store containing the first wireless LAN information.

Referring to FIG. 15, the matching rate of the MAC address is 75% (three of all four MAC addresses match). Also, the difference in signal intensity assigned to AP1 to AP3 is 0.4, 1.8, 0.25, and 4, respectively, and the difference in signal strength is less than 10 in all. Therefore, the check-in determination unit 307 determines that the customer checked in the store.

The above example has been described on the basis of the first and second wireless LAN information selected on the basis of the third embodiment, and it is possible to judge the check-in likewise based on the first, second and fourth embodiments. That is, in the first embodiment, one AP is stored in the first and second wireless LAN information in each store, and it can be seen that the AP is checked in if the information is identical to each other.

The check-in determiner 307 generates check-in information when the customer determines that the customer has checked in the store containing the first WLAN information, and transmits the generated check-in information to the visit determining unit 308 and the inflow path calculating unit The movement path calculation unit 309). When the check-in information is received from the check-in determination unit 307, the visit determination unit 308 receives the second wireless LAN information acquisition time from the second wireless LAN information input unit 306 at a predetermined time period. The visit determining unit 308 can calculate the time that the customer stayed in the store based on the second wireless LAN information acquisition time. For example, assuming that the second wireless LAN information is acquired every 30 seconds, the acquired time of the wireless LAN information is 14:00:00, 14:00:30, 14:01:00, 14:01:30 In this case, the customer's stay time is assumed to be 1 minute and 30 seconds in total.

The visit determination unit 308 can determine that the customer visited the store only when the residence time is out of a predetermined value. In addition, if the customer is determined to have visited the store, the customer visit information can be generated. The visit information can be stored in a separate DB and utilized for commercial analysis. The distinction between check-in and visit is to avoid seeing as a visit if the actual customer stops at the store for a short time (for example, if the customer is mistakenly entering the store).

 For example, when the residence time is set to 5 minutes, if the residence time lasts for one minute, it can be determined that the customer has not visited the store. Conversely, if the residence time lasts 5 minutes and 30 seconds, it is determined that the customer has visited the store. Therefore, the visit determination unit 308 of the present invention determines that the customer who has passed through the store simply by checking in has not visited the store, and thus can enhance the reliability of the commercial analysis.

When the check-in information is received from the check-in determining unit 307, the inflow path calculating unit 309 of the present invention receives the store information from the store information DB 350 and receives the store information from the second wireless LAN information input unit 306 2 wireless LAN information acquisition time. 16, the inflow path calculation unit 309 calculates an indoor inflow route (indoor or outdoor travel route) that the customer has passed based on the latitude and longitude of the store checked in by the customer and the second wireless LAN information acquisition time . Analysis of the inflow path reveals that the customer is moving from the northeast to the southwest. Of course, in this case, the customer's travel route can be calculated based on the second wireless LAN information transmitted from the customer. That is, the information of each indoor store (the GPS information, the address information, etc., which is the location information of the store) is registered in the server 300 in advance, and the customer can use the second wireless LAN information transmitted from the customer The server 300 can know. The server can analyze the store visited by the customer and accurately calculate the route and the visit shop.

The server 300 of the present invention may further include a re-registration signal generator 310. The re-registration signal generator 310 receives the store location information including the first wireless LAN information from the store information DB 350 and transmits the second wireless LAN information from the second wireless LAN information input unit 306 And receive the customer visit information from the visit determination unit 308. [ The re-registration signal generator 310 compares the first wireless LAN information with the second wireless LAN information for a predetermined period (for example, six months) after receiving the customer visiting information from the visit determining unit 308 When the difference between the first wireless LAN information and the second wireless LAN information is out of a predetermined error range, counts the number of times out of the error range, and when the counting number is out of the first number (for example, twice) Registration signal for re-registering the first wireless LAN information and transmit the fifth re-registration signal to the location registration terminal 200.

The re-registration signal generator 310 determines whether the MAC address matching rate of the first wireless LAN information (in this case, the first wireless LAN information is legitimately registered in the server) and the second wireless LAN information is 60% It can be determined that the error range is out of range when the signal intensity difference assigned to the MAC address is 10 or more. In addition, when the number of times counted in the error range is two, the re-registration signal generator 310 may generate a fifth re-registration signal for re-registering the first wireless LAN information and transmit the fifth re-registration signal to the re-registration signal receiver 260 . When receiving the fifth re-registration signal from the re-registration signal receiving unit 260, the location registration terminal 200 returns to the first step and transmits an indoor photograph matched with the new first wireless LAN information to the information input unit 310 The re-registration procedure is newly performed.

Referring to FIG. 17, when the MAC address of the second wireless LAN information measured on August 30, 2016 is compared with the MAC address of the first wireless LAN information already registered, three out of four do not match. In this case, when calculating the MAC address matching rate, only one of all four MAC addresses is matched, so that the MAC address matching rate is 25%. In this case, the MAC address matching rate is smaller than the predetermined matching rate of 60%. Therefore, the re-registration signal generator 310 determines that the second wireless LAN information is out of the error range, and counts the number of times the error range is out of one. 17, if the MAC addresses of the first wireless LAN information and the second wireless LAN information are compared with each other based on the second wireless LAN information measured on February 28, 2017, 100%. However, the difference between the signal strengths of the second and third access points is 118.2 and 20.25, respectively, which is out of 10. Therefore, the re-registration signal generator 310 determines that the second wireless LAN information is out of the error range, and counts the number of times the error range is out of two. The re-registration signal generating unit 310 may generate a fifth re-registration signal for re-registering the first wireless LAN information and transmit the fifth re-registration signal to the re-registration signal receiving unit 260 when the number of times out of the error range is two . In this case, the store may be closed, a new store may be opened, or the first WLAN information may be incorrectly registered.

In addition, the server 300 may further include a commercial transaction analyzing unit 311. As described above, the merchandise analysis unit 311 can analyze the merchandise by using it when the customer checks in, visits the store, calculates the travel route, or closes the store. That is, for example, if the merchandise analysis unit 311 determines that the shop is closed due to the fact that the Wi-Fi installed in the store is removed or the owner of the store is changed and the MAC address of the Wi-Fi changes frequently, can do. Furthermore, each store can be divided into sectors according to the address of the store by the server, and if many stores are closed and opened during the store located in the A sector zone (the opening of the MAC address of the registered first wireless LAN information The sector analyzing unit 311 can determine that the sector A is inferior to the sector B in the sector B, as shown in FIG. Furthermore, the closing rate can also be calculated. That is, the merchandise analysis unit 311 may calculate the closing rate by counting the number of closed stores and dividing the number of stores by the number of stores. For example, if the total number of stores in the first building is 20, and the number of stores that are judged to be closed is 2, the closing rate is calculated as 10%. If the total number of stores in the second building is 30, and the number of stores that are deemed to have been closed is six, the closing rate will be calculated as 20%. This closing rate can be used to analyze the commercial value of each building.

The server 300 may further include a merchandise analysis DB unit 312. The merchandise analysis DB can store store visit information and commercial area analysis information. The merchandise analysis DB unit 312 can deliver the store visit information and the merchandise analysis information to the terminal installed with the third application. The third application may transmit the commercial information analysis information and the store information to a person who desires to operate the store or a store operator.
