Then, information on the density and other location information are transmitted to the user's mobile terminal 10.

As illustrated in FIG. 3, the mobile terminal 30 of another user may include an input unit 310, a communication unit 320, an output unit 330, a memory 340, a control unit 370, and the like. Since some of the components are the same as those of the user's mobile terminal 10 in terms of configuration and function, detailed descriptions of the same components will be omitted.

The communication unit 320 is a module for obtaining the location (or current location) of the mobile terminal 30 and includes at least one of a GPS module and a WiFi (Wireless Fidelity) module.

The GPS module calculates distance information and accurate time information from three or more satellites, and then applies a trigonometry to the calculated information, thereby accurately calculating three-dimensional current location information according to latitude, longitude, and altitude. Currently, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module can calculate speed information by continuously calculating the current location in real time. However, it is difficult to accurately measure the location of a mobile terminal using a GPS module in a shaded area of a satellite signal, such as indoors. Accordingly, in order to compensate for positioning of the GPS method, a WiFi Positioning System (WPS) may be used.

The Wi-Fi positioning system (WPS: WiFi Positioning System) uses a WiFi module provided in the mobile terminal 30 and a wireless access point (AP) for transmitting or receiving a wireless signal with the WiFi module. As a technology for tracking the location of a device, it refers to a location positioning technology based on WLAN (Wireless Local Area Network) using WiFi. The Wi-Fi location tracking system may include a Wi-Fi location location server, a mobile terminal 30, a wireless AP connected to the mobile terminal 30, and a database in which information about a wireless AP is stored. The mobile terminal 30 connected to the wireless AP may transmit a location information request message to the Wi-Fi location location server. The Wi-Fi location server extracts information on the wireless AP connected to the mobile terminal 30 based on the location information request message (or signal) of the mobile terminal 30. The information on the wireless AP connected to the mobile terminal 30 may be transmitted to the Wi-Fi location server through the mobile terminal 30 or from the wireless AP to the Wi-Fi location server.

Based on the location information request message of the mobile terminal 30, the extracted wireless AP information includes MAC Address, SSID (Service Set IDentification), RSSI (Received Signal Strength Indicator), RSRP (Reference Signal Received Power), RSRQ ( Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi location server may receive information on a wireless AP connected to the mobile terminal 30 and extract wireless AP information corresponding to a wireless AP to which the mobile terminal is connected from a pre-built database. At this time, the information of random wireless APs stored in the database includes MAC Address, SSID, channel information, Privacy, Network Type, latitude and longitude coordinates of the wireless AP, the building name where the wireless AP is located, the number of floors, and detailed indoor location information (GPS coordinates). Available), the AP owner's address, phone number, etc. In this case, in order to remove wireless APs provided using mobile APs or illegal MAC addresses during the positioning process, the Wi-Fi location positioning server may extract only a predetermined number of wireless AP information in the order of the highest RSSI. Thereafter, the Wi-Fi location positioning server may extract (or analyze) the location information of the mobile terminal 30 by using at least one wireless AP information extracted from the database. By comparing the included information with the received wireless AP information, location information of the mobile terminal 30 is extracted (or analyzed).

As a method for extracting (or analyzing) the location information of the mobile terminal 30, a Cell-ID method, a finger print method, a triangulation method, a landmark method, and the like may be used. The Cell-ID method is a method of determining a location of a wireless AP having the strongest signal strength among surrounding wireless AP information collected by the mobile terminal as the location of the mobile terminal. It is simple to implement, does not incur additional costs, and has the advantage of being able to obtain location information quickly, but has a disadvantage in that the positioning accuracy is lowered when the installation density of the wireless AP is low. The fingerprint method is a method of selecting a reference location in a service area, collecting signal strength information, and estimating a location through signal strength information transmitted from a mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to make a database of propagation characteristics in advance. The triangulation method is a method of calculating a location of a mobile terminal based on coordinates of at least three wireless APs and a distance between the mobile terminals. In order to measure the distance between the mobile terminal and the wireless AP, the signal strength is converted into distance information, or the time at which the wireless signal is transmitted (Time of Arrival, ToA), and the time difference at which the signal is transmitted (Time Difference of Arrival, TDoA) , The angle at which the signal is transmitted (Angle of Arrival, AoA), etc. may be used. The landmark method is a method of measuring the location of a mobile terminal using a landmark transmitter that knows the location. In addition to the listed methods, various algorithms may be used as a method for extracting (or analyzing) the location information of the mobile terminal.

The location information of the mobile terminal 30 extracted in this way is transmitted to the mobile terminal 30 through the Wi-Fi location positioning server, so that the mobile terminal 30 can obtain the location information.

The mobile terminal 30 may obtain location information by being connected to at least one wireless AP. In this case, the number of wireless APs required to obtain the location information of the mobile terminal 30 may be variously changed according to the wireless communication environment in which the mobile terminal 30 is located.

Hereinafter, a method of providing place information using the place information providing system according to the present invention will be described.

First, as shown in FIG. 4, the user generates and transmits a request signal for requesting place information of a specific location using the mobile terminal 10 (S11). At this time, the user can select a desired location or place (eg, tourist attraction, attraction, restaurant, etc.) by using the location information providing application of the mobile terminal 10, and want to know about this place (eg, You can select the visitor's real-time density, the visitor's waiting time, business hours, parking information, the weather of the place, the latest video/photo, etc.) or enter a search word. Accordingly, the request signal includes at least one of a location/place selected by the user, selected content, and input search word.

The server 20 receives a request signal from the user's mobile terminal 10, and generates place information for a place selected by the user according to the request signal.

For example, when a user requests a real-time visitor density of a corresponding place, the server 20 identifies the mobile terminals 30 of other users in a specific location/range and determines the number of the mobile terminals 30 in real time. And, based on this, the visitor density of the corresponding place can be determined in real time (S12). Here, the visitor density may be expressed by the number of mobile terminals 30 of other users or by location information of each mobile terminal 30. That is, the visitor density is transmitted to the mobile terminal 10 as information representing the number of mobile terminals 30 of other users or the location information of each mobile terminal 30, and the visitor density is displayed on the screen using the number or location information. Can be visualized on the image.

In order to check the number of mobile terminals 30 of other users, the server 20 logs in to the place information providing application and determines the number of mobile terminals 30 of other users connected in real time or more than a reference time. During this time, the number of mobile terminals 30 of other users connected to the wireless communication network at the specific location may be determined in real time.

In addition, the server 20 determines the number of mobile terminals 30 of other users in the specific location by time, and based on the number of mobile terminals 30 determined by time, You can judge the number of visitors. In addition, the server 20 may store the number of visitors by time or transmit it to the user's mobile terminal 10. Accordingly, the user can check the number of visitors by time and visit the corresponding place during a time when there are few visitors.

When the user requests other information (for example, the waiting time of the visitor, parking information) other than the visitor density of the corresponding place through the request signal (selected content, search word), the server 20 based on the request signal Data related to the specific location uploaded by the mobile terminals 30 of other users who were in the place during (for example, 1 hour ago to the present) or present, for example, the waiting time of the visitor and parking information Related reviews, videos, photos, etc. are searched in the server 20 (S13). In this case, the server 20 may search by data upload time, and may preferentially search for data actually uploaded from the corresponding place. It is preferable that the data include location information of the corresponding place or location information of the mobile terminal 30 so that the location where the data is uploaded can be identified.

Thereafter, the server 20 determines whether data uploaded by the mobile terminals 30 of other users in the corresponding place have been searched (S14). If data related to the specific location uploaded by the mobile terminals 30 of other users is searched, the server 20 generates place information including the searched data and visitor density, and sends the data to the mobile terminal 10 of the user. Transmit (S17).

If the data related to the specific location uploaded by the mobile terminals 30 of other users is not searched in the server 20, the server 20 is the other user based on the request signal (selected content, search word). It is possible to request transmission of data related to the specific location to at least one of the mobile terminals 30, for example, data related to the waiting time and parking information of the visitor (S15).

At this time, the server 20 determines the priority of the mobile terminals 30 of other users based on the stored other user information (eg, gender, age, residence, etc.), and according to the determined priority. At least one of the mobile terminals 30 of another user is requested to transmit data related to the specific location. The server 20 may request a questionnaire related to the specific location from at least one of the mobile terminals 30 of another user or request a video or photo related to the specific location.

Thereafter, the mobile terminal 30 of another user generates data related to the specific location and transmits it to the server 20 (S16). It is preferable that the data generated by the mobile terminal 30 of another user include location information of a corresponding place or location information of the mobile terminal 30.

The server 20 generates place information including data transmitted from the mobile terminal 30 of another user and the visitor density, and transmits it to the mobile terminal 10 of the user (S17).

The user's mobile terminal 10 can visualize the received place information on the screen. For example, in order to visualize the visitor density, the mobile terminals 30 of other users in the corresponding place The number may be displayed as a number on the screen of the mobile terminal 10 or the location of each mobile terminal 30 may be displayed as a dot on the map screen based on the location information of the mobile terminals 30. In addition, in order to visualize the waiting time of the visitor, data retrieved by the server 20 or data transmitted from the mobile terminal 30 of another user may be displayed on the screen of the mobile terminal 10.
