Referring to FIG. 1, the dual-mode terminal 101 to which the present invention is applied is short-range wirelessly connected to the Internet through a short-range wireless communication network 102 in addition to a mobile communication interface that can be connected to the mobile communication network 103 as described above. A mobile communication terminal having an interface. In general, the mobile communication network 103 has coverage formed over most of the space except for some shaded areas such as inside buildings, underground parking lots, and tunnels, while the short-range wireless communication network 202 is mainly used for homes and offices. Coverage is formed in the interior spaces or in public hot spots such as cafes, airports, train stations, hotels, amusement parks, and so on.

In the location-based service system according to the present invention, the location-based service zone 100 uses the above-described characteristics to establish a location-based wireless communication coverage unit, that is, a building internal space such as a home or office, or a cafe, airport, train station, hotel, amusement park, By limiting to a public hotspot unit, such as this, it is possible to effectively provide location-based services in a small area unit.

That is, in the conventional mobile communication system, since the location of the terminal has been identified as a base station unit having a relatively wide coverage, the location-based service of a small area unit could not be effectively provided, but as described above, according to the method provided by the present invention. Since the location information of the dual mode terminal can be managed by the coverage unit of the local area network, the mobile service provider or the service provider can effectively perform the location-based service of the small area unit through the mobile communication network 103 or the local area network 102. It can be provided.

Referring to FIG. 16, when the dual mode terminal 101 enters the location-based service zone, the dual mode terminal 101 accesses the local area network 102 covering the location-based service zone and acquires location information of the location-based service zone. (s1601).

 Subsequently, when the user requests a pop-type service such as a product list search service or a product location search service by using the dual mode terminal 101, the dual mode terminal 101 may request this information from the current location-based service zone information. The transfer to the application server 105 together (s1602). The application server provides the dual mode terminal 101 with an information service corresponding to the location based on the location information from the dual mode terminal 101 (S1603).

FIG. 17 is a signal flowchart illustrating a processing procedure for providing a pop-type supplementary service in a location-based service system to which network network location information management according to an exemplary embodiment of the present invention is applied.

Referring to FIG. 17, when the dual mode terminal 101 enters the location based service zone and accesses the local area wireless communication network 102 covering the location based service zone, the local area wireless communication network 102 is connected to the dual mode terminal ( After obtaining the information of 101, the location information is registered in the location management server 104 (s1701, s1702, s1703).

 Subsequently, when the user requests the application server 105 using a dual mode terminal 101 to provide a pop-type service such as a product list search service and a product location search service, the application server 105 may request a location management server ( After requesting 104 to find the location information of the corresponding dual mode terminal 101, an information service corresponding to the location is provided to the dual mode terminal 101 (s1704, s1705, s1706, s1707).

On the other hand, in the embodiment of the present invention has been described with respect to specific embodiments, of course, various modifications are possible without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the appended claims, but also by the equivalents of the claims.

According to the present invention, since the location of the dual-mode terminal can be determined through a short range wireless communication interface such as WLAN, Bluetooth, UWB, ZigBee, low power RF, and RFID, the mobile service provider sends location-based advertisements and discount coupons through the mobile communication network. It is possible to increase sales by providing location-based PoP type services such as push type service marketing, product list search service, and product location search service.
