Abstract: PURPOSE: A method and a system for estimating the location of a terminal on base station basis are provided to accurately estimate the location of the terminal in consideration with signal transmission direction information of the base station. CONSTITUTION: A base station signal information receiver(510) receives base station signal information about the base station signal. The base station signal is transmitted from one or more base station to the terminal. A base station information receiver(520) receives the signal transfer direction information. A location estimator(540) estimates the location of the terminal in consideration of the base station signal information.

Abstract: A method and a system for determining a location of a mobile communication terminal are provided to measure similarity between signal pattern data of the terminal requesting location determination and signal pattern data recorded in a pattern database, and determine the location of the terminal by using the selected similar signal pattern data, thereby selecting similar signal pattern data having high similarity. A method for determining a location of a mobile communication terminal comprises the following steps of: recording and maintaining first collected signal pattern data in a pattern database in association with location information(S210); receiving second signal pattern data from the mobile communication terminal requesting location determination(S220); calculating a distance measure with respect to the received second signal pattern data and the first signal pattern data recorded in the pattern database, and selecting one or more similar signal pattern data corresponding to the second signal pattern data among the first signal pattern data by using the distance measure(S230); and generating final location information of the mobile communication terminal based on the selected similar signal pattern data(S240).

Abstract: A method and an apparatus for determining a moving direction of a mobile terminal by using a signal dragging effect are provided to determine a moving direction of a mobile terminal being moved without complicated vector calculation by a GPS device. A positioning unit(210) determines a location of a mobile terminal based on base station information. A moving direction determining unit(220) determines a moving direction of the mobile terminal based on the location information of the mobile terminal and base station location information included in the base station information. The positioning unit determines a location of the mobile terminal based on a base station signal received from the base station and the base station information corresponding to the base station signal.

Abstract: A system and a method for managing supply chain using an ETC(Electronic Transaction Code) are provided to automatically and quickly check completion of delivery without any manual process, and reduce time and expense needed for the delivery. An order information database(220) stores goods order information. A goods database(230) stores information for goods inventory of each warehouse. A controller(210) transmits the goods order information and the ETC to a supplier and the orderer system of the warehouse by searching the warehouse storing the goods from the goods database after receiving a goods order from the orderer system. The controller completes the goods order by receiving delivery completion information from the orderer system. The supplier system includes an information receiver for receiving the ETC and the goods order information from the controller, and a tag writer for writing the received ETC and goods order information to an electronic tag.
