衛星と携帯電話装置の基地局からなる通信システムを示す図である。 It illustrates a communication system comprising a base station of a satellite and the mobile telephone device. 図3は発呼者端末、被呼者端末と携帯電話装置の基地局間の通信の状態を示すタイムチャートである。 Figure 3 is a time chart showing the state of the communication between the calling terminal, the base station of the mobile telephone device and the called party terminal. 【0016】発呼者端末と被呼者端末は、1秒ごとに更新される複数のGPS衛星からの位置情報を受信して現在位置を算出し、夫々のRAM(13)に記憶する。 The calling terminal and the called terminal receives position information from a plurality of GPS satellites that are updated every second and calculates the current position is stored in each of the RAM (13). 発呼者端末のテンキー(151)により被呼者端末の番号が入力され、通話キー(152)が押されると、発呼者端末は基地局に被呼者端末を呼び出す呼出信号を基地局に送信する。 The number of the called terminal is input by the numeric keypad (151) of the calling terminal, the call key (152) is pressed, the calling terminal is a call signal for calling the called terminal to the base station to the base station Send. このとき、発呼者端末の現在位置情報も基地局に送信する。 At this time, also to the base station current location information of the calling terminal. 【0017】基地局は、呼出信号と発呼者番号と発呼者の現在位置情報を被呼者端末に送信する。 [0017] The base station transmits the current location information of the calling signal and the calling party number and the calling party to the called party terminal. これらを受信した被呼者端末は、スピーカ(8)で着信音を鳴らし、 These called party terminal which has received the sound the ring tone speaker (8),
表示部(14)に発呼者番号を表示する。 To display the caller's number on the display unit (14). また、被呼者の現在位置と受信した発呼者端末の現在位置より発呼者端末までの距離と方向を計算し、方位センサ(18)で求められた方位に一致させて、表示部(14)に発呼者端末の方向と距離を表示する。 Moreover, to calculate the distance and direction to the calling terminal from the current location of the calling terminal and the received current position of the called party, to match the azimuth obtained by the azimuth sensor (18), a display unit ( 14) to display the direction and distance of the calling terminal. 【0018】被呼者端末の通話キー(152)が押されると、被呼者端末は応答信号と被呼者端末の現在位置を基地局に送信する。 [0018] call key of the called party terminal (152) is pressed, the called terminal sends the current position of the response signal and the called party terminal to the base station. これらを受信した基地局は発呼者端末に応答信号と被呼者端末の現在位置を基地局に送信する。 Base station receiving these transmits the current position of the response signal and the called party terminal to the base station to the calling terminal. 被呼者端末の現在位置を受信した発呼者端末は被呼者端末までの距離と方向を計算し、方位センサ(18) Caller terminal receiving the current location of the called terminal computes the distance and direction to the callee terminal, a direction sensor (18)
で求められた方位に一致させて、表示部(14)に被呼者端末の方向と距離を表示する。 In to match the orientation obtained, and displays the direction and distance of the called terminal to the display unit (14). 【0019】尚、例えば、ディスプレイ情報(付加情報)の領域に現在位置情報を入れれば、被呼者端末が着信に応答する前に発呼者端末の現在位置情報を被呼者端末に送信することができるし、通話中に被呼者端末の現在位置情報を発呼者端末に送信することもできる。 [0019] Incidentally, for example, if you put the current location information in the area of ​​the display information (additional information), it transmits the current location information of the calling terminal before the called terminal responds to the incoming to the called terminal it can, it is also possible to transmit the current position information of the called terminal to the calling terminal during a call. 【0020】本発明は方位センサにより、通話相手(発呼者あるいは被呼者)の方向を絶対方向(地球に対する方向)で表示する。 [0020] The present invention is by the azimuth sensor, and displays the direction of the other party (caller or called party) in absolute direction (direction with respect to the earth). 例えば、図4に示す如く、使用者が携帯電話装置の表示部(14)の画面の上部を北に向けており、通話相手が東北に位置していると仮定すると、 For example, as shown in FIG. 4, the user has directed the top of the screen of the display unit of the mobile telephone device (14) to the north, assuming the other party is located in the northeast,
画面の右上方向の矢印を表示する。 To display the upper right direction of the arrow on the screen. そこで、使用者が画面の上部を東に向けると、図5に示す如く、左上方向の矢印を表示する。 Therefore, the user Turning top of the screen to the east, as shown in FIG. 5, and displays the top-left direction of the arrow. 【0021】これにより、携帯電話装置の向きに関係なく、通話相手の絶対方向と距離を使用者に知らせることができる。 [0021] As a result, regardless of the orientation of the mobile phone device, it is possible to tell the absolute direction and distance of the other party to the user. 本発明は、地図に重畳して相手の位置を表示する方法と比較すると、表示画面が小さくてもよい点、 The present invention is different from the method of displaying the position of the other party is superimposed on the map, it may point even with a small display screen,
地図情報を記憶する必要が無い点、方向が明確にわかる点が優れている。 That there is no need to store the map information, it is better that clearly shows direction. 尚、本実施例では、距離を視覚的に表示させたが、音声で距離を報知させてもよい。 In the present embodiment, the distance visually display the, it may be informed the distance by voice. 【0022】また、本発明は、被呼者の携帯電話装置が着信応答する前に、発呼者の位置を知ることができるため、使用者は発呼者の位置を参考に着信応答することができる。 Further, the present invention, before the portable telephone device of the called party to call response, since it is possible to know the location of the calling party, the user that incoming call response to reference the location of the calling party can. 例えば、発呼者が近傍であったり、自宅であったときは着信に応答しない。 For example, it does not respond to the incoming call when the caller is or in the vicinity, was home. 【0023】尚、着信応答の参考にするために、着信応答前に発呼者の位置を報知する方法は、上述の方法に限定するものではない。 [0023] Incidentally, the For reference arrival response, a method of notifying a location of the calling party before the incoming response is not limited to the above method. 方向は示さずに距離のみを報知させてもよいし、地図表示に発呼者の位置を重畳してもよいし、発呼者に位置に対応した地名や名称を報知してもよい。 Direction to only be a by alert distance without exhibiting, may be superimposed the position of the caller on the map display, you may be notified of the place names or names corresponding to the position to the calling party. 【0024】また、上述の実施例は現在位置を検出する方法としてGPSを使用したが、これに限定するものではない。 Further, although the above embodiment used the GPS as a method of detecting the current position, not limited thereto. 例えば、携帯電話が近傍の基地局やビーコンよりその位置情報を受信してもよい。 For example, a mobile phone may receive the location information from the base station or beacon vicinity. 【0025】 【発明の効果】本発明は、被呼者の携帯電話装置が着信応答する前に、発呼者の位置を知ることができるため、 [0025] According to the present invention, before the portable telephone device of the called party to call response, since it is possible to know the location of the calling party,
被呼者は発呼者の位置を参考に着信応答することができる。 The called party can be called in response to reference the location of the calling party.
