The present invention relates to a location-based service system, and more particularly, to a location-based service method for exchanging information with each other using a global positioning system (GPS) and wireless data communication in a location-based service system.

In general, Location-Based Service (LBS) is a standardized service using a network to provide location-based application in TS 22.071 of 3rd Generation Partnership Project (3GPP), and location in Open GIS Consortium (OGC). Each application is called any application software service that works by accessing, providing, or locating information, and the Federal Communication Commission (FCC) defines mobile users to receive services for their geographic location, location, or known entity. Each is defined in various forms, and in general, it can be regarded as a general term for various application systems and services that accurately locate and utilize people or objects.

Recently, the location-based service has become the most growthable new service field according to the development of internet and mobile communication technology and service technology and the evolution of location-based service devices such as mobile phones, PDAs, and navigation.

The location information of the location-based service apparatus is identified by a nearby base station (BS) or an access point (AP) that communicates with each other, and provides service information desired by the user when a request for service information is made from the user.

In addition, the next-generation location-based services of the GPS (Global Positioning System) method using satellites have been gradually expanded, and the technology has been developed to more accurately grasp the location of the location-based service device using GPS and provide various types of information. .

However, the GPS-based location-based service device utilized in the conventional railroad field cannot exchange information with location-based service devices provided in other railroad cars, and is fixed such as its location information and the history of a pre-stored map database. Since only facility information was provided, the engineer operating the railroad car had to rely on his or her empirical memory to determine the distance and location of the stationary facility, and also to move the stationary vehicle such as other railcars or temporary facilities in motion. There is a problem in that a safety accident cannot be prepared in advance because the information on the facility is not fully recognized in advance. Therefore, there is a need for improving the conventional location based service system.

In the embodiment of the present invention, in order for the communication server 150 to transmit location information of another location-based service device to at least one location-based service device, a predetermined distance for retrieving location information of another location-based service device is 10 km. It was illustrated as a reference.

For example, when the location information is received from the first location-based service device 110 in the communication server 150, the unique ID code and the location coordinates of the received location information are checked to be within 10 km based on the identified location coordinates. By retrieving the location information of other location-based service devices located, only the location information received from the retrieved other location-based service devices is transmitted to the first location-based service device 110.
