The present invention relates to a mobile terminal service, and in particular, when a subscriber selects a location information providing menu when a subscriber of the mobile terminal requests accurate location information of the subscriber during a call with the receiver, the subscriber's location is measured in the mobile communication system, and the subscriber The present invention relates to a method for providing subscriber location information using a mobile terminal for providing location information to a mobile terminal of a receiver.

In general, a location based service (LBS) is a location information based service that utilizes a mobile communication network and information technology (IT) as a whole. As a result of the advancement of mobile communication networks such as IMT-2000 and intelligent transportation system (ITS), It is a technology that has been in the spotlight in the fields of logistics, logistics, and e-commerce. In the mobile communication environment, the user's location information is the most important and necessary situation information for providing a situation recognition service. Currently, various location-based services such as public safety services, location tracking services, navigation services, and information provision services are provided using GPS or mobile network based location recognition systems. In the next generation mobile communication environment, it is expected that precise location recognition will be possible in indoor, underground or dense building areas that existing location recognition system cannot cover due to the limitation of wireless environment.

For example, a mobile communication subscriber may grasp his location using a mobile terminal in a complex room such as a shopping mall, a museum, an airport, or may receive various location recognition services based on the location. In particular, in the next generation mobile communication environment where location recognition and networking are possible anytime, much more location-based services may be provided. For example, a user may be provided navigation services using location information, such as location information, user schedules, and preferred public transport, from home to overseas business travel destinations. You can also be automatically provided with a reservation service.

Global positioning system (GPS) is a global radio navigation satellite system developed and promoted by the US Department of Defense. It is also called NAVSTAR / GPS in the sense of a system using the navigation system with time and ranging (NAVSTAR), a medium- and high-orbit navigation satellite system. The system consists of a total of 24 navigating satellites, each of which was launched on six circular orbits at an altitude of approximately 20,000 km, a period of about 12 hours, and an orbital inclination of 55 °, a ground control station that manages satellites, and a user's mobile station.

Each satellite is equipped with an atomic clock. Since the system is arranged so that at least four satellites are always in view of the earth at all times, the user selects four suitable ones from these satellites and receives time signals from them to measure each distance. Since the positions of the four satellites are known, this measurement shows the user's latitude, longitude, and altitude in three-dimensional positions and the time deviation of the field of view. The transmit frequency from the satellite is two waves, L1 (1,575.42 MHz) and L2 (1,227.6 MHz), which compensate for ionospheric delay. The navigation signal contains 50bps of navigation information and is a spread spectrum modulated phase shift keying (PSK) signal with a pseudo noise code (PN code). There are two kinds of pseudo noise codes, P code (precision code) and C / A code (clear and acquisition code). The P code is 10.23 Mbps, and the period is 1 week for precise positioning. The C / A code is 1.023 Mbps and the period is about 1 millisecond (ms). These pseudo-noise codes can be used to decode the navigation signal or to measure the distance between the satellite and the receiving station. L1 contains the P code and the C / A code, and L2 contains only the P code. Currently, the C / A code has a publicly available code pattern, but the P code is secret. It is known that the position measurement accuracy by C / A code is within 100m of nominal, and the precision by P code is within 16m of nominal. The satellite positioning system was originally built for the positioning of military vehicles, ships and aircraft. Nowadays, it can be used by civilians, so it is used for navigation devices installed in automobiles, navigation devices such as ships and helicopters. It is also used for remote control of unmanned construction vehicles and tectonic fluctuation measuring systems for earthquake forecasts. In recent years, the market has been rapidly expanding, because navigation systems combined with geographic information contained in read-only compact disc storage devices (CD-ROMs) can be provided at a relatively low cost.

Hereinafter, a location information service using a mobile terminal will be described in detail.
