The present invention relates to a location tracking method and a system using a wireless communication network, and in particular, to transmit the location data of a user received from a GPS (Global Positioning System) satellite network to a location tracking server via a wireless data network, the location tracking server The present invention relates to a location tracking method and system using a wireless communication network that tracks a user's moving path by using a dedicated algorithm and displays the contents on a map and view the contents through a web.

Mobile communication companies of conventional PDA (Personal Digital Assistant) and PCS (Personal Communications Services) phones are using location information service using a base station, but are used as an additional service of wireless communication devices because they are not dedicated devices. Therefore, when users subscribed to the mobile communication service provider apply for and use the location information service, the use fee is very expensive without providing accurate location information. That is, the location information service provided by the mobile communication company is a level that only informs the predetermined area where the user is located. In particular, the location information service provided by the mobile telecommunication company cannot be used at all in a rural area or a remote area without a base station.

In order to solve this disadvantage, conventionally, a location tracking system using a GPS (satellite positioning system) has been introduced.

The GPS was developed by the US Department of Defense in the early 1970's and began operation in full swing in the mid-1990s. The GPS is the most ideal navigation system available globally, regardless of time or weather conditions.It was originally developed for military use, but has rapidly expanded into civilian use due to its economic and usefulness, and is now the most common navigation system. Hold.

For example, various moving objects such as ships, aircrafts, and automobiles are equipped with a GPS positioning device for checking the current position and moving speed or determining a moving path. The GPS positioning device receives radio waves representing latitude, longitude, altitude, etc. from three or more satellites located in six mid tracks and calculates the current position of the moving object, and the calculated result is output to the display of the navigation device.

Therefore, the navigation device synthesizes the information of the calculated current position into pre-stored map information, as well as the position of the moving object, the moving direction of the moving object, the distance to the destination, the current speed of the moving object, and the path set before the user moves. It provides the user with various information necessary for driving such as road information and recommended route to the destination.

However, since the conventional GPS is not connected with the Internet or the Geographic Information System (GIS), there is a disadvantage in that the user cannot provide more various location tracking functions.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to transmit the location data of a user received from a GPS satellite network to a location tracking server via a wireless data network, and in the location tracking server a dedicated algorithm The present invention provides a location tracking method and system using a wireless communication network that tracks the movement path of the user, displays it on a map, and displays the contents through a web.
