And an apparatus and method for measuring the quality of location-based services by statistically providing environmental analysis in a location area.

Since the Internet communication service, which is symbolized by the World Wide Web, has been in the spotlight, communication service has already made a big difference in human life in all aspects of society, economy and politics. It is hard to imagine life without the Internet, and the Internet is a part of life. Therefore, in recent years, the use of various high-speed communication networks, such as in order to use a variety of communication services in a better environment has increased significantly.

In addition, in recent years, a number of companies have been developing technology for wireless Internet to provide a communication service that transcends space. The wireless Internet service is a combination of mobile communication and the Internet, and refers to a service that can wirelessly transmit and receive Internet information while on the move. The wireless Internet service is an advanced personalization service according to the use of a user's terminal and has a feature of providing a unique information based on the user's mobility. In particular, recently, Location Based Services (LBS) has been highlighted among various wireless Internet services.

Location-based services are based on mobile terminals such as mobile phones, personal digital assistants (PDAs), and notebook PCs to accurately identify the location of a person or object, and collectively refer to additional information services related to the identified location and a system therefor. Location-based services include spatial information processing technologies such as mobile communication technology, Internet technology, mobile terminal technology, Geographical Information System (GIS), Global Positioning System (GPS), Intelligent Transport System (ITS), and various contents technologies. The service is expected to explode in the future due to integration.

In order to use the location-based service, it is essential to know the location of the wireless communication terminal. Currently, as a method of identifying a location using wireless communication, a method using GPS is typical.

GPS is a system that can be located anywhere in the world by 24 GPS satellites orbiting the earth at an altitude of about 20,000 kilometers. GPS uses radio waves in the 1.5 GHz band and has a coordination center called Control Station on the ground to collect and synchronize information from GPS satellites. The user also knows the current location through the GPS receiver. In general, triangulation is used as a method for identifying a location using GPS. To determine the location using GPS, a total of four GPS satellites are required, including three satellites for triangulation and one observation satellite for time error.

In more detail, since GPS already knows the position of each of the three satellites, the GPS is positioned by measuring the distance between the satellite and the GPS receiver. The distance from the satellite to the GPS receiver takes advantage of the difference between the time when the radio waves are sent from the satellite and the time when the GPS receiver receives the radio waves. The time difference thus obtained is called propagation propagation time, and the distance can be calculated by multiplying the propagation propagation time by the speed of light.

On the other hand, the location-based services described up to now, due to various functions, convenience, etc., the use range and the number of users are rapidly increasing. Accordingly, the location-based service provider intends to provide an optimized location-based service by measuring the quality and related information of the constructed location-based service system in order to provide a more accurate and high quality location-based service to the user. However, the quality measurement of the current location-based service system does not vary in the elements of quality measurement, and the quality measurement results are simply provided as a list of parameter messages. As such, there is a problem in that there is a limitation in providing an optimized location-based service because the quality measurement factors are not diverse and precise quality analysis is difficult only with a simple list of parameter messages.

In order to solve the above problems, the present invention provides a statistical analysis of call processing analysis of location-based services and environmental analysis in a location area by using various types of quality measurement data measured in a wireless environment providing location-based services. An object of the present invention is to provide an apparatus and method for measuring the quality of location-based services.
