Among various wireless Internet services using wireless terminals, in particular, LBS (Location Based Service) has gained much attention due to its wide usability and convenience. Location-based service refers to a communication service that locates a wireless terminal such as a mobile phone and a personal digital assistant (PDA) and provides additional information related to the identified location.

As shown in Figures 2 and 3, the terminal positioning system according to an embodiment of the present invention includes a terminal 200, an AP 210, a communication network 220, some or all of the positioning device 230.

The terminal 200 in the embodiment of the present invention can be applied to various wired and wireless environments, and is classified into a personal digital assistant (PDA), a cellular phone, a smart phone, and the like by a communication type, and a personal communication service (PCS) phone that is classified by a communication method. , Global System for Mobile (GSM) phones, Wideband CDMA (W-CDMA) phones, CDMA-2000 phones, Mobile Broadband System (MBS) phones, Long Term Evolution (LTE) phones, and the like. Here, the MBS phone is a terminal to be used in the next generation system which is currently discussed. In addition, the terminal 200 may further include a desktop computer, a laptop computer, a netbook and a tablet PC, and a cloud terminal used under a cloud computing environment.

The terminal 200 may include a wireless communication module and a wireless LAN module, and may further include a GPS module. As the wireless communication module is provided, the terminal 200 connects to the communication network 220 to perform normal voice or data communication with the other party, and via the AP 210 that is recognized around the wireless LAN module. It connects to the communication network 220 and receives various web page data. Furthermore, since the terminal 200 includes a GPS module, the terminal 200 receives data provided through the GPS satellites.

The terminal 200 includes a wireless application protocol (WAP), which is an Internet access protocol, a Microsoft Internet Explorer (MIE) based on HTML using an HTTP protocol, a handheld device transport protocol (HDPT), and an NTT. DoKoMo's i-Mode or a specific carrier's wireless Internet connection browser is used to access the Internet via the communication network 220. Among the Internet access protocols used by the terminal 200, MIE uses m-HTML, which is a shortened version of HTML, and a language called compact HTML (c-HTML), which is a subset of HTML in the case of i-Mode. do.

Recently, a terminal 200 such as a smartphone uses a browser for wireless Internet access of a specific telecommunication company such as Opera Mini for iPhone to provide a faster wireless internet, or in conjunction with the terminal 200 in close proximity. Wi-Fi and WiBro networks are also used to provide wireless high-speed Internet.

The AP 210 is a small base station, such as a femto or pico base station, which is frequently installed in a building, and serves to relay signals for communication between two different devices. Here, the femto or pico base station is classified according to how many terminals 200 can be connected in the classification of the small base station. According to an embodiment of the present invention, the AP 210 includes a short range communication module for performing short range communication such as Wi-Fi with the terminal 200. Accordingly, the AP 210 may extract the location of the data packet, specify the best communication path for the extracted location, and forward the data packet to the next device, for example, the terminal 200, along the designated communication path.

The AP 210 may share several circuits in a general network environment, and may include, for example, a router, a repeater, a repeater, and the like. According to an embodiment of the present invention, the short range communication of the AP 210 may include, for example, a radio frequency (RF) and a second such as Bluetooth, zigbee, infrared (IrDA), ultra high frequency (UHF) and very high frequency (VHF). It may be performed in various standards such as wideband (UWB) communication. In FIG. 2, the AP 210 is illustrated as being separately configured from the communication network 220, but since the AP 210 may be included in the communication network 220, the present invention will not be particularly limited thereto.

AP 210 according to an embodiment of the present invention has a plurality of WLAN module and antenna structure for transmitting a control signal, such as a beacon (Becon) as a multiple signal. Even when there is no data to be transmitted from the AP 210, the beacon is always transmitted periodically. Here, the beacon is, for example, a signal that is periodically transmitted to inform the terminal 200 of an operation area, a transmission standard, a frequency band, a beacon transmission period, and ID information of the AP 210 in the case of a wireless LAN. to be. According to an embodiment of the present invention, as shown in FIG. 3, when the AP 210 generating multiple signals is installed in a boundary area in which a particular area is to be divided for an arbitrary area, the division of the area is clearly defined. You can do it. For example, if the AP 210 is installed to transmit multiple signals in the boundary area to distinguish between the specific designated area and the area between the shop and the store, it is easy to distinguish the zone / store. Detailed information regarding the other AP 210 will be described later.

The communication network 220 includes both wired and wireless communication networks. For example, the communication network 220 may be applied to a CDMA network, a WCDMA network, a GSM network, and a cloud computing network under a cloud computing environment as an access network of a next generation mobile communication system to be implemented in the future. In this case, a device such as a base station, a NodeB, and an e-NodeB constituting the communication network 220 may be referred to as a node.

The positioning device 230 includes a DB 230a including WLAN information and p-Cell information. Herein, the WLAN information is AP information of the AP 210 for performing short-range communication such as Wi-Fi, and the p-Cell information divides the national map into a grid cell form, and the MAC address information and node for each grid cell. And information matching the AP information, POI information, and the like. For example, when performing the positioning of the terminal 200, AP information such as MAC address information of the AP 210 is received from the terminal 200, and the positioning device 230 is a terminal defined in an optimal grid cell selected using the positioning information. The location information, that is, the coordinate value of the 200, may be provided to the terminal 200 as a positioning result, or POI information matching the location information may be provided to the terminal 200 as a positioning result. Alternatively, an optimal positioning result may be calculated using a triangulation technique, a survey technique using finger print recognition, or the like using a plurality of coordinate values defined in a grid cell.

Meanwhile, the positioning device 230 according to the embodiment of the present invention may perform a separate DB construction process for performing positioning using multiple signals from the AP 210. In other words, after collecting the signal strength of the grid to form a pCell DB, in the case of the fingerprint (Finger Print) method of transmitting the positioning results in the coordinates of the grid most similar to the signal collected when the positioning request, the installation location of the AP 210 In the triangulation technique of calculating the positioning result based on the installation position of the AP 210 when performing the positioning of the terminal 200, N cover areas may use the same AP position. Since it is common, positioning accuracy is inevitably deteriorated. Accordingly, in the embodiment of the present invention, when using triangulation, a separate process for finally providing a positioning result may be performed.

First, the AP 210 for transmitting a multi-signal calculates a maximum output that can transmit a signal and a maximum distance R that can receive a signal through experiments, and then in a table form as shown in Table 1 below. Save it.

Then, the direction direction angle θ of the antenna is a reference line of the target region, for example, as an angle difference between a line segment extending eastward from the center of the target region and a direction in which the radio wave is emitted from the antenna as shown in FIG. 4. Decided.

The virtual AP position coordinates (px, py) moved from the installation position coordinates (x, y) of the AP 210 are calculated using the maximum reach distance R and the direction direction angle θ of the antenna. This may be represented as in Equation 1.

In this case, Equation 1 is applied only to the first quadrant, and in the other quadrant, the positioning device 230 may calculate the virtual AP position coordinates (px, py) using Equation 2.

For example, in case of an AP manufactured to transmit four multiple signals, four virtual AP position coordinates may be obtained as shown in FIG. 5.

Then, when triangulating, the positioning result may be calculated and provided to the terminal 200 by performing a triangulation algorithm using virtual AP position coordinates (px, py). For example, the virtual location coordinates (px, py) and the weight (W _i ) of the AP 210 can be obtained by using the N MAC addresses and signal strengths received from the terminal 200, and through this, the actual positioning position ( rx, ry) can be calculated. The relation is expressed as in Equation 3. Here, the weight (W _i) refers to a weight that is proportional to the signal strength of the AP (210).

In order to perform the above function, as shown in FIG. 6, the positioning device 230 includes a traffic processing unit 600, a virtual position coordinate calculation unit 610, a virtual position coordinate extraction unit 620, and a positioning result providing unit ( 630). Here, the traffic processing unit 600 may include a control unit and an interface unit, and the control unit may be a signal processed in connection with the virtual position coordinate calculation unit 610, the virtual position coordinate extraction unit 620, and the positioning result providing unit 630. Alternatively, the information is generally controlled, and the interface unit performs a process such as signal or information conversion. The virtual position coordinate calculation unit 610 is a virtual for any point moved from the installation position coordinates (x, y) of the AP 210 for each sector with respect to the AP 210 for transmitting signals for each sector in different directions. The position coordinates (px, py) are calculated, and the virtual position coordinate extraction unit 620 extracts the virtual position coordinates based on the AP information of the AP 210 provided at the positioning request of the terminal 200, and the positioning result. The provider 630 calculates the positioning result using the extracted virtual position coordinates and provides the calculated result to the terminal 200. In this case, the virtual position coordinate calculator 610 divides the sector into one quadrant to four quadrants based on the maximum distance calculator for calculating the maximum distance R of the signal of the AP 210 for each sector and the AP 210. By including an angle determiner that determines an angle between the reference line and the direction in which the signal propagates, the virtual position coordinates may be calculated using the maximum distance R and the angle θ.

Of course, although FIG. 6 illustrates that all the components are combined or operated in one, the present invention is not necessarily limited to these embodiments. In other words, all of the components may be selectively combined to operate within one or more of the scope of the present invention. In addition, all of the components may be implemented as one independent hardware, for example, the virtual position coordinate calculation unit 610, the virtual position coordinate extraction unit 620 and the positioning result providing unit 630 of FIG. Some or all of the elements may be selectively combined to be implemented as a computer program having a program module that performs some or all of the functions combined in one or a plurality of hardware. Codes and code segments constituting the computer program may be easily inferred by those skilled in the art. Such a computer program is embodied in an embodiment of the present invention by being stored in a computer readable storage medium (Computer Readable Media) to be read and executed by a computer. The storage medium of the computer program may include a magnetic recording medium, an optical recording medium, a carrier wave medium, and the like.

It can be used for driving the integrated circuit (IC). For voltage conversion, the power supply unit 710 may include an inverter for converting AC into DC, a DC-DC converter for adjusting the voltage level of DC, and the like.

The WLAN module 740 includes first to Nth WLAN modules 740_1 and 740_N for transmitting multiple signals, and each of the WLAN modules 740_1 and 740_N generates a WLAN signal. For example, in the WLAN module 740, the first to Nth WLAN modules 740_1 and 740_N are the same WLAN signal, for example, a Bluetooth signal, a Zigbee, or a WiFi signal. Although it is preferable to transmit a signal, some may be configured as a Bluetooth module and others may be configured in various ways such as a ZigBee or Wi-Fi module, and thus embodiments of the present invention are not particularly limited to what signals are configured to be transmitted. will be.

Each antenna 750 is preferably configured to correspond to the first to Nth WLAN modules 740_1 and 740_N in one-to-one correspondence, but one antenna 750 processes signals of the plurality of WLAN modules 740. In the embodiment of the present invention, the present invention is not particularly limited. For example, in the case of a dual antenna or a multi-band processing antenna, a signal corresponding to the same frequency band may be provided in a plurality of paths, or signals of different frequency bands may be processed.

FIG. 8 is a diagram illustrating an AP having a dual structure for transmitting two multiple signals. FIG. 8A is a diagram illustrating an internal structure of an AP in which two WLAN modules of FIG. 7 are implemented. (B) is a diagram showing an example in which FIG. 8 (a) is applied to a fingerprint cell grid cell, and FIG. 9 is a diagram showing an example of using an AP for transmitting four multiple signals.

Referring to FIG. 8 together with FIGS. 2 and 7, the AP 210 according to an embodiment of the present invention includes a part 800 or a part of the case 800, the barrier layer 810, the substrate 820, and the antenna 830. .

In this case, the case 800 includes an accommodation space to form an outer frame, and for example, may be formed of various materials of a poly series. The shape may form various shapes such as a square or a circle.

The blocking film 810 divides the storage space of the case 800 to have a plurality of storage areas, for example, two storage areas as shown in FIG. 8, and may be formed of the same material as the material of the case 800 or may be made of a different material. Can be formed. The blocking layer 810 may prevent signal interference between the wireless LAN module 740 or the antennas 750 and 830 electrically connected to the wireless LAN module 740 mounted on the substrate 820 accommodated in each storage space. If so, it can be formed of various materials.

The substrate 820 is, for example, a printed circuit board (PCB), as well as the wireless LAN module 740 of FIG. 7, a part of the control unit 700, the power supply unit 710, the interface unit 720, and the clock generator 730. It can be configured to include all.

The antenna 830 is electrically connected to the WLAN module 740 on the substrate 820 and disposed outside the case 800. In FIG. 8A, the side of the case 800 is illustrated in order to reduce signal interference, but it may be disposed in any area unless signal interference occurs with each other. In view of this, although not shown in a separate drawing, for example, when one antenna 830 is formed to process a signal of the same frequency band or a signal of different frequency bands in any position of the case 800 It may be deployed.

Other details are not different from those described with reference to FIG.

If the AP 210 is designed to transmit four multiple signals as shown in FIG. 9 (b), even if one AP 210 is installed in an arbitrary target area, precise positioning can be performed for each sector. In addition, since only one AP 210 may be installed in the center of the area where the conventional four APs are installed as shown in FIG. 1B, the cost can be reduced by that amount. In other words, assuming that a particular company or company installs the AP 210 in any target area for providing a precise positioning service, a purchase price and a power construction cost of the AP 210 are generated. As such, by installing as few APs as possible, the economics can be guaranteed. That is, in the conventional method, four APs should be installed in order to distinguish four areas as shown in FIG. 9A.
