摘要： At least three base stations transmit a specific signal pattern at given intervals. This allows a mobile station that received this signal pattern to locate itself by using the positional information about the base stations, sending timing (or information on phase shift from the reference time) of each signal pattern from the base stations, and signal pattern receiving time information. At least one of the above base stations changes the sending timing of the signal pattern. On this occasion, the mobile terminal or station is notified of the altered reference time offset (or information on phase shift from the reference time) of the sending timing or updated sending timing of the signal pattern.

摘要： In a positioning system using the time difference of arrival of signals between a station and a plurality of access points, each of the access points repeatedly measures a signal for calculating a position from the station, while changing any of time, the position of the station, and a frequency in use, and accumulates a plurality of measurement data. A position calculation server determines a given timing on each of a plurality of delay profiles created based on the measurement data obtained from the access points as a reception timing sample for the signal, performs a combination process with respect to the plurality of reception timing samples, and determines one reception timing for each of the access points. The position calculation server calculates the time difference of arrival of signals between the station and the access points based on the reception timings and calculates the coordinates of the position of the station.

摘要： The disclosed invention provides a wireless communications terminal apparatus that calculates its accurate position, eliminating the influence of a repeater on the calculation without using complicated processing. The terminal apparatus receives signals transmitted from a plurality of radio stations and calculates its position, using the received signals. The terminal apparatus comprises repeater detection means for detecting a signal from a repeater which transmits signals that are generated on the basis of signals transmitted from one of the radio stations and indistinguishable from the signals transmitted from that radio station from among the received signals and position calculation means for calculating its position. When the repeater detection means has detected a signal from a repeater, the position calculation means ignores the detected signal from the repeater and calculates the terminal position, using the received signals from other radio stations.
