Abstract: A method and an apparatus for judging the existence of a signal transmitted through a repeater are provided to effectively correct a positioning error generated due to the existence of a repeater in a positioning system by judging whether a transmitted signal has been through a repeater. Using the strength information of transmitted signals, a signal judgement part judges an estimated repeater signal as a signal transmitted from a base station if the strength of the estimated repeater signal is smaller than the minimum critical strength(S910). In case the strength of the estimated repeater signal is larger than the minimum critical strength, however, the signal judgement part judges whether a signal received from another sector of the base station exists(S920). If such a signal doesn't exist, the signal judgement part judges whether the strength of the estimated repeater signal is larger than a call stabilization strength(S930). If so, the signal judgement part judges the estimated repeater signal as a signal transmitted through a repeater.
Abstract translation: 提供一种用于判断通过中继器发送的信号的存在的方法和装置，用于通过判断发送信号是否已经通过中继器来有效地校正由于定位系统中的中继器的存在而产生的定位误差。 如果所估计的中继器信号的强度小于最小临界强度，则使用传输信号的强度信息，信号判断部分将估计的中继器信号判断为从基站发送的信号（S910）。 然而，在估计中继器信号的强度大于最小临界强度的情况下，信号判断部分判断从基站的另一扇区接收到的信号是否存在（S920）。 如果这样的信号不存在，信号判断部判定估计中继信号的强度是否比呼叫稳定强度大（S930）。 如果是，则信号判断部将估计的中继器信号判定为通过中继器发送的信号。

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 positioning system of a mobile communication terminal for improving position measurement technology through self learning algorithm and a method thereof are provided to self revise BS(Base Station) information or environmental variables by using accuracy in GPS(Global Positioning System)-based positioning results, so as to improve network-based positioning technology without a separate additional cost. The first self learning DB(340) accumulates GPS-based positioning results, network information for BS identification, and network-based positioning results. A self learning processor(330) conducts a self learning process by using the accumulated results and information, and generates self learning processing results associated with the network-based positioning. The second self learning DB(350) accumulates the self learning processing results by matching the results with BS information. A network-based positioning unit(320) generates the network-based positioning results through the network-based positioning, and updates the generated results in the first self learning DB(340).
