And a location information signal transmitter 240 and a key for transmitting a location information signal including a transmission method determiner 230 and an AP location separator to the location server 300. It includes a database 250 that stores data for each key.

Table 1 below shows the data stored in the database 250 according to an embodiment of the present invention.

Table 1

Referring to Table 1, the database 250 includes a key and data (Data). The key is a Wi-Fi MAC address that can be managed and stored as “00: 1f: 1f: 54: 0d: ac”.

The data includes the AP location identifier, the IP address of the location server, and the port number of the location server. In addition, the data may further include a transmission period and a registration date.

AP location separator is a unique number for the Wi-Fi AP 100, for example, if the AP location separator is "KR00101", the front "KR001" is used as a separator to distinguish the company, the "01" after May be used as a number for identifying a specific one of the plurality of Wi-Fi APs 100.

For example, the transmission period is utilized for the purpose of processing as if the Wi-Fi AP 100 once detected by the terminal 200 is not detected during the recognition period, and adjusted by minute, such as "10," 20 ". Can be set.

The IP address of the location server indicates the IP address of the location server 300 that receives the location information signal transmitted by the terminal 200, and may be stored as, for example, "168.154.240.1".

The port number of the location server indicates the port number of the location server 300 that receives the location information signal transmitted by the terminal 200 and may be stored, for example, as "7000".

The registration date indicates a year, month, and day when the key and data for each key are stored in the database 250. For example, the registration date may be stored as "2011.01.01".

Hereinafter, a method of obtaining location information according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

The Wi-Fi AP 100 transmits a Wi-Fi MAC address (S10). The transmission power output of the Wi-Fi AP 100 may be changed, and the reach range of the Wi-Fi MAC address reaching the terminal 200 may be changed by adjusting the transmission power output of the Wi-Fi AP 100. In addition, the Wi-Fi MAC address transmission period can be adjusted by the designer within 50 ~ 1,024ms. It is effective to set a specific period within 500 ~ 1,024ms.

Here, the Wi-Fi MAC address is a unique address assigned to the Wi-Fi AP manufacturer for each Wi-Fi AP 100 and has a 12-digit structure such as “00: 08: 9f: 16: 53: 0f”.

The Wi-Fi MAC address search unit 210 searches for at least one Wi-Fi MAC address transmitted by the at least one Wi-Fi AP 100 (S20). At this time, according to the distance between the Wi-Fi AP 100 and the terminal 200, the received radio wave strength of the Wi-Fi AP 100 recognized by the terminal 200 is different, and the terminal 200 is the Wi-Fi AP 100 It is possible to predict the distance of the Wi-Fi AP 100 from the terminal 200 by the received radio wave strength, and the terminal 200 is Wi-Fi desired to receive at the terminal 200 by the Wi-Fi AP 100 received radio wave strength The distance of the AP 100 can be adjusted.

The server determiner 220 determines the location server 300 by comparing the retrieved Wi-Fi MAC address with the data stored in the database 250. That is, the server determination unit 220 finds the Wi-Fi MAC address, which is a key matching the retrieved Wi-Fi MAC address, from the database 250 and the IP of the positioning server 300 according to each Wi-Fi MAC address. The location server 300 is determined by checking the address and the port number of the location server 300. In this case, the server determination unit 220 may check the AP location separator stored in the database 250 and check the Wi-Fi AP 100 that has transmitted the Wi-Fi MAC address. If the specific Wi-Fi MAC address information retrieved by the Wi-Fi MAC address retrieval unit 210 is not stored as a key in the database 250, the server determination unit 220 may determine the Wi-Fi MAC address. Discards the other Wi-Fi MAC address found.

The transmission method determination unit 230 determines a location information signal transmission method, which is a signal transmitted from the location information signal transmission unit 240 (S40). For example, the location information signal transmission method may use a Wi-Fi communication network and / or a data communication network of a mobile communication company.

The location information signal transmitter 240 transmits the location information signal to the location server 300 (S50). When transmitting the location information signal, do not retransmit the location information signal during the transmission period.

Referring to FIG. 4, the location information signal is a signal transmitted by the terminal 200 according to the present invention and received by the positioning server 300. The location information signal is an AP location separator, a phone number of the terminal 200, and Wi. -Fi MAC address contains the time when it was found. In addition, the location information signal may include other data. For example, the other data may further include a service set identifier (SSID), a Bluetooth address, a terminal type, a Wi-Fi AP reception radio wave strength, and a transmission period. .

The location server 300 receives the location information signal transmitted from the terminal 200 (S60). By using the location information signal received from the positioning server 300 to determine the location of the user using the terminal 200 is used to provide the best services to customers in hotels, restaurants, department stores, duty-free shops, golf courses, financial institutions, etc. In addition, it can be used in various fields such as location based service.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but it is only for the purpose of describing the present invention, and those skilled in the art to which the present invention pertains various modifications or equivalents from the detailed description of the invention. It will be appreciated that one embodiment is possible. Therefore, the true scope of the present invention should be determined by the technical spirit of the claims.
