## Abstract

PROBLEM TO BE SOLVED: To make a system graspable the position of a PHS or a portable telephone.
SOLUTION: The difference of distance is calculated on the basis of the difference between radio-wave arrival times from a transmitter 104 in two receiving points 101, 102 of receivers A, B. The position of the transmitter 104 is found on hyperbolic lines 105, 106 which have the two receiving points 101, 102 as focuses. Regarding the receiving point 103 of a third receiver C, similar hyperbolic lines 107, 108, 109, 110 are found between the receivers A, B. The point of intersection of the three hyperbolic lines is found. Thereby, the position of the PHS or the portable telephone is grasped. Information on the grasped position can be collated as character information or image information by a personal computer or the portable telephone through the Internet.

【発明の属する技術分野】本発明は、ＰＨＳ，携帯電話の位置を検知するシステムに関するものである。 BACKGROUND OF THE INVENTION The present invention relates to a system for detecting the PHS, mobile phone location.

【0002】 [0002]

【従来の技術】ＰＨＳ，携帯電話が所在する基地局を把握し，その基地局のカバーするエリアを情報提供する方法がある。 BACKGROUND ART PHS, mobile phone to know the base station located, there is a method of providing an area covered by that base station information.

【0003】また、ＰＨＳ，携帯電話にＧＰＳ機能を持たせ、衛星からの電波により、自局の緯度、経度を把握する方法がある。 [0003], PHS, to have a GPS function to the cellular phone, the radio waves from the satellite, there is a method to grasp the latitude, the longitude of the own station. 既知の衛星からの電波の伝達遅延時間を測定し、電波の伝達速度より、距離に換算する。 Measuring the radio wave propagation delay time from a known satellite, from radio wave transmission speed is converted into a distance. 衛星より一定の距離の地点が球面として連続的に捉えられる。 Point a certain distance from the satellite can be continuously viewed as spherical.

【0004】尚、ＰＨＳ，携帯電話の位置を検知するシステムではないが、関連する技術として次のものがある。 [0004], PHS, but not the system senses the position of the mobile phone, there are the following ones as the related art. 電波航法としての双曲線航法である。 It is a hyperbolic navigation as a radio navigation. 場所が既知である２ Location is known 2
つの発信点からの電波の到達時間差を測定する。 One of measuring the arrival time difference of the radio wave from the transmitter point. 到達時間差が一定の位置は、２つの発信点を焦点とする双曲線となる。 Constant position arrival time difference is a hyperbola two outgoing point and focal. もう一組の電波源からも同様に放射する電波の到達時間差を測定し、２つの発信点を焦点とする双曲線を計算する。 Measuring the arrival time difference of the radio wave radiated similarly from another set of radio sources, the two outgoing point to calculate the hyperbola focus. この2組の双曲線の交点が電波受信点の位置を示す。 The two sets of hyperbolas the intersection indicates the position of the radio wave reception points.

【0005】また、移動局の位置を双曲線航法を用いて標定する技術がある（特開平6-3428）。 Further, there is a technique for locating using the hyperbolic navigation position of the mobile station (JP 6-3428). １つの移動局からの第1の測定用信号を親局と複数の中継局で受信するとともに、各中継局は重複しない固有の遅延時間後に第２の測定用信号を同一周波数で送信し、親局が移動局からの第１の測定用信号と中継局からの第２の測定用信号とを受信してその到達時間差または位相差を測定することにより、第１の測定用信号を親局が受信した時刻と各中継局が受信した時刻との相対時間差を算出して双曲線航法により、移動局の位置を算出する。 Which receives the first measurement signal from one mobile station in the parent station and a plurality of relay stations, the relay station transmits at the same frequency the second measurement signal after delay time specific non-overlapping, parent by station measures the first second of the arrival time difference or phase difference by receiving the measurement signal from the measurement signal and the relay station from the mobile station, the first measurement signal is a master station the hyperbolic navigation received time and the relay station to calculate the relative time difference between the time received, it calculates the position of the mobile station.
