Hereinafter, the main configuration and operation method of the terminal 100 according to the embodiment of the present invention will be described.

FIG. 5 is a block diagram illustrating a main configuration of a terminal according to an embodiment of the present invention shown in FIG.

1 and 5, a terminal 100 according to an exemplary embodiment of the present invention includes a signal receiving module 110, a signal strength checking module 120, a filtering module 130, a binding box processing module 140, A location determination module 150, and a service device interworking module 160.

Here, 'module' is a component that performs a predetermined function, and may be implemented by hardware, software, or a combination of hardware and software. For example, the 'module' may refer to a program module, which may be software components executed by a processor to perform certain functions, object-oriented software components, class components, Data, databases, data structures, tables, arrays, data structures, and the like, such as, for example, , And variables. In addition, the functions provided in the components and 'modules' may be combined into a smaller number of components and '~ modules' or further separated into additional components and 'modules'.

To be more specific, the signal receiving module 110 sets a frequency band and performs a process of scanning a channel supported in the set frequency band . For example, the signal receiving module 110 of the terminal 100 sets a frequency band of 2.4 GHz, and performs a process of scanning a channel supported by the frequency band one channel at a time from the lowest channel to the highest channel.

The signal receiving module 110 may be configured to search for and search at least one or more access point devices 201, 202, 203, 204, 205, And the like).

In particular, the signal receiving module 110 of the present invention searches the access point devices 201, 202, 203, 204, 205, ... through the respective channels and searches the access point devices 201, 202, 203, 204, 205, ..., and the scanning procedure may include a passive scanning and an active scanning procedure.

Passive scanning means that the signal reception module 110 of the terminal 100 sequentially listens to each channel one by one and transmits a beacon transmitted from the access point apparatuses 201, 202, 203, 204, 205, 202, 203, 204, 205, ...) from the beacon message by waiting for a beacon message to arrive from the beacon message.

On the other hand, in the active scanning, after the terminal 100 sends a probe request message to each channel, it detects the activity of the channel during the minimum channel time (MinChannelTime) on the corresponding channel. If there is no response from the channel during the minimum channel time, the signal receiving module 110 of the terminal 100 scans the next channel. If motion is detected in the channel within the minimum channel time, the signal receiving module 110 of the terminal 100 waits for a probe response message until a maximum channel time (MaxChannelTime), and the maximum channel time (MaxChannelTime ), And then performs a procedure of scanning the next channel in the same manner.

The signal strength confirmation module 120 checks the reception strength of a signal received through the signal reception module 110 (120). That is, the reception intensity of the beacon signal, that is, RSSI (Received Signal Strength Indication), of the access point devices 201, 202, 203, 204, 205, ... identified through the signal reception module 110 is measured.

The filtering module 130 filters only the access points 201, 202, 203, 204, 205, ..., which are equal to or greater than a predetermined value based on the reception intensity, in order to further improve the accuracy of the position estimation . At this time, the filtering module 130 can select two or more, preferably three, access point devices having appropriate intensity ranges, and supports performing terminal position estimation using the selected access point device. In addition, the predetermined value of the filtering module 130 may be changed depending on user setting or system setting.

Then, the binding box processing module 140 sets a binding box using the received strength determined through the signal strength checking module 120. In particular, the binding box processing module 140 may set a circular binding box to be in inverse proportion to the reception intensity based on the access point devices 201, 202, 203, 204, 205, ....

A service device interworking module for transmitting the identification information of the access point to which the signal is received through the signal receiving module and the measured reception intensity to the service device and receiving the estimated current location information from the service device;
The terminal further comprising: A terminal interworking module that receives information on the measured strength of the signal received from the access point apparatus and the identification information of the access point apparatus from the terminal and transmits the estimated terminal position through the terminal position determination module to the terminal;
A binding box processing module for setting a binding box for position estimation using the reception strength; And
A terminal position determination module for extracting a contact point of the binding box and estimating a position of the current terminal using the extracted contact point;
The service device comprising: 16. The method of claim 15,
A filtering module for selecting only the access point device when the reception strength is equal to or greater than a preset value;
Further comprising: means for determining whether the service is available. 16. The method of claim 15,
When the terminal interworking module receives only the access point identification information from the terminal,
Wherein the terminal location determination module confirms location information corresponding to the access point identification information and transmits the location information to the terminal through the terminal interworking module. A terminal for receiving a signal from at least one access point located within a predetermined radius, measuring a reception intensity of the received signal, transmitting the measured reception strength and identification information of the access point to a service device; And
A binding box for location estimation is set based on the reception intensity at a location of the access point apparatus and the contact point of the binding box is extracted A service device for estimating a current position of the terminal using the extracted contact point;
