Selective indoor positioning method beetween TDoA and pattern matching using RSSI

According to the invention, a method for positioning a position of the terminal, (a) step of selecting a plurality of the base station analyzes the PN pilot signals received by the terminal by the reception signal level threshold value or more signals to the positioning target signal; And (b) when the number of the positioning target signal more than two, using the three or more positioning target signal for performing a positioning operation of the terminal through the TDoA approach, enhanced TDoA and pattern using the RSSI there is provided a selective indoor positioning between the matching method. According to an optional indoor positioning method between the enhanced TDoA the pattern matching using the disclosed RSSI, may be by the use of only a select signal, thereby increasing the reliability of the positioning, because it uses only the signals above the threshold it may have a lower system complexity than conventional technology, in the TDoA approach but it does not have to be applied to address the limited positioning problem, according to the pattern matching method is applied, and can provide a reliable and accurate positioning result than the conventional positioning method.
