1 to 2 are views illustrating a location tracking system of a mobile phone in a conventional mobile communication network to track the location of a mobile terminal subscriber in a non line of sight environment in which multi-path fading occurs. have.

The mobile communication network includes a plurality of base stations (BTS) 21, 22, 23, 24 that provide mobile communication services to mobile subscribers through a mobile communication terminal, and a base station that controls the plurality of base stations. A base station controller (BSC) 30, a mobile communication with a mobile switching center (MSC) 50 that connects the base station controller (BSC) to another base station or public switched network (PSTN) and manages location information. It consists of a Home Location Register (HLR) that is connected to the exchange and manages the subscriber's location.

The cellular mobile communication network divides the entire mobile communication service area into a plurality of base stations (BTSs) to form cells, which are small service areas, and centrally controls these base stations to mobile switching stations, thereby allowing subscribers to move between cells. Provide communication.

The mobile switching center 50 can determine which cell is located by which subscriber, thereby reducing the time required to call the subscriber. As described above, finding a location of a mobile subscriber located in an arbitrary cell in a mobile communication network is called a location service.

Methods of tracking the location of an arbitrary mobile communication terminal in a mobile communication network include a method of tracking a location in a mobile communication terminal using GPS and a method of tracking a location in a mobile communication network.

A method of tracking a location in a mobile communication terminal using GPS is to install a Global Positioning System (GPS) receiver in a mobile communication terminal and use the location information received from three or four satellites through the GPS receiver. Calculate your own position as latitude and longitude.

A method for tracking a location in a mobile communication network is to calculate the location of a mobile communication terminal holder itself through trigonometry based on a specific signal received from at least three base stations.

In the method performed in a network, three or more base stations receive a specific signal transmitted from a mobile communication terminal, obtain a distance between each base station and the mobile communication terminal using the arrival time, and then use a trigonometry to determine the location of the mobile communication terminal. Calculate This method is typically provided by a Location Data Processor 40, which may be included within a Base Station Controller (BSC) or may exist independently. When a user requests a location tracking service for a specific mobile subscriber, i.e., a mobile terminal, the base station controller (BSC) 30 considers the location of the mobile terminal to use the base stations 21 and 22 for the location tracking service. 23).

As described above, a method of calculating a position of a mobile communication terminal in a mobile communication network includes a method of using a time of arrival (TOA) and a method of using a time difference of arrival (TDOA).

The method using the TOA uses the distance between the mobile communication terminal and the base station calculated based on the time when a specific signal is propagated from the mobile communication terminal to the base station. That is, it is determined that the mobile communication terminal is located at a point where three circles having a radius between the three or more base stations and the mobile communication terminal intersect each other.

In a method using TDOA, a method in which three or more base stations determine that a mobile communication terminal is located at a point where three or more hyperbolic lines meet by using a set of points where a difference in a signal received from the mobile communication terminal is constant, that is, a hyperbolic curve, is used. to be. Compared to the TOA method, this method has a burden of precisely synchronizing with each base station, but in a synchronous CDMA system, it is not a problem because all base stations are synchronized with each other using a GPS receiver.

2 is a diagram illustrating a location tracking method of a mobile communication terminal according to a conventional TOA method. Each distance between three or more base stations 21, 22, 23, and the mobile communication terminal 10 is represented. The three circles 101, 102, 103 of radius generate an overlapping area 1, and the mobile communication terminal 10 will exist within the overlapping area 1.

The method for tracking the position of the mobile communication terminal in the overlapped area 1 is performed by using three common circles when three or more circles are not met at one point, but when three or more circles are overlapped and three overlapped areas are generated. It is determined that the mobile phone is located at the intersection of the common strings. In this case, the common string is defined as a straight line connecting two points generated by crossing two circles. In the method of tracking the location of the mobile communication terminal using a common string, the accuracy is not high except that the mobile communication terminals are at a similar distance from the base stations and the radio environments between the base stations and the mobile communication terminals are similar to each other.
