Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device that displays the position information of the other party.

[0002]

2. Description of the Related Art In the case of a wired telephone device, the location where the wired telephone device is installed is entered in a subscriber registration document. Therefore, the telephone exchange can know the installation location of the wired telephone device. Therefore, in the wired telephone device, it has been considered that the called party receives the caller's installation location from the telephone exchange and displays it when the calling party makes a call (Japanese Patent Laid-Open No. 61-16).
9060 publication). This allows the called party to know where the telephone device of the calling party is installed.

[0003]

However, since the position of the portable telephone device to be carried does not have the installation location, the telephone exchange cannot know the position of the portable telephone device, and the conventional method cannot generate the portable telephone device. The location of the caller could not be reported.

Further, the calling party position described in JP-A-61-169060 is displayed after the called party answers the incoming call. Therefore, the called party could not answer the incoming call with reference to the position of the calling party of the mobile phone device. For example, if the caller is in the vicinity, there is no need for a call, but an incoming call is answered.

[0005]

The portable telephone device of the present invention has been made in view of the above-mentioned points, and the position detecting means for detecting the position of the own device and the position information of the own device together with the calling signal at the time of calling. The communication device includes a communication unit that transmits and receives the position information of the calling party device when called, and a notification unit that notifies the position information of the calling party before the incoming call response when the position information of the calling party device is received when called.

Further, a GPS receiving unit for detecting the current position, a communication means for transmitting the current position information of the own device together with a calling signal at the time of calling and receiving the current position information of the calling party device at the time of receiving a call, and a display Section and the current position information of the calling party device when receiving a call, the direction and distance of the calling party are calculated from the current position of the calling party device and the current position of the own device, and the direction and distance are displayed on the display unit. A control means for displaying the message before answering the incoming call is provided.

ng System) receiving unit, which converts the electric wave of the current position information captured by the GPS antenna (17) into an electric signal and outputs the electric signal to the control circuit (11). (18) is an azimuth sensor, which detects the azimuth in absolute azimuth by utilizing the geomagnetism.

Next, a method of displaying the current position information of the calling party on the mobile phone device of the called party will be described. FIG. 2 shows a mobile phone device of a calling party (hereinafter referred to as a calling party terminal), a mobile phone device of a called party (hereinafter referred to as a called party terminal), and a GPS.
It is a figure which shows the communication system which consists of a satellite and the base station of a mobile telephone apparatus. FIG. 3 is a time chart showing the state of communication between the calling terminal, the called terminal and the base station of the mobile phone device.

The caller terminal and the callee terminal receive position information from a plurality of GPS satellites updated every second, calculate current positions, and store them in the respective RAMs (13). When the number of the called terminal is input by the ten key (151) of the calling terminal and the call key (152) is pressed, the calling terminal sends a call signal to the base station to call the called terminal to the base station. Send. At this time, the current location information of the calling terminal is also transmitted to the base station.

The base station transmits the calling signal, the calling party number, and the current position information of the calling party to the called party terminal. The called terminal receiving these sounds the ringing tone through the speaker (8),
The calling number is displayed on the display unit (14). In addition, the distance and direction from the current position of the called party and the current position of the received caller terminal to the caller terminal are calculated, and they are matched with the direction obtained by the direction sensor (18), and the display unit ( The direction and distance of the calling terminal are displayed in 14).

When the call key (152) of the called terminal is pressed, the called terminal transmits a response signal and the current location of the called terminal to the base station. Upon receiving these, the base station transmits a response signal to the calling terminal and the current position of the called terminal to the base station. The calling terminal that has received the current position of the called terminal calculates the distance and the direction to the called terminal, and the direction sensor (18)
The direction and distance of the called terminal are displayed on the display unit (14) in conformity with the azimuth obtained in step (14).

Incidentally, for example, if the current position information is entered in the display information (additional information) area, the current position information of the calling terminal is transmitted to the called terminal before the called terminal answers the incoming call. It is also possible to transmit the current position information of the called terminal to the calling terminal during a call.

According to the present invention, the direction of the calling party (caller or called party) is displayed by the direction sensor in the absolute direction (direction with respect to the earth). For example, as shown in FIG. 4, assuming that the user points the upper part of the screen of the display unit (14) of the mobile phone device to the north and the call partner is located in the Tohoku region,
Display an arrow pointing to the upper right of the screen. Therefore, when the user turns the upper part of the screen to the east, an arrow pointing to the upper left is displayed as shown in FIG.

Thus, the user can be informed of the absolute direction and distance of the other party of the call regardless of the orientation of the portable telephone device. Compared with the method of displaying the position of the other party by superimposing on the map, the present invention may have a small display screen,
The advantage is that there is no need to memorize map information and the direction can be clearly understood. Although the distance is visually displayed in the present embodiment, the distance may be notified by voice.

Further, according to the present invention, since the position of the calling party can be known before the callee's portable telephone device answers the incoming call, the user can answer the incoming call with reference to the position of the calling party. You can For example, when the caller is near or at home, the caller does not answer the incoming call.

For reference of the incoming call response, the method of notifying the caller's position before the incoming call response is not limited to the above method. Only the distance may be notified without indicating the direction, the position of the calling party may be superimposed on the map display, or the place name or name corresponding to the position may be notified to the calling party.

In the above embodiment, GPS is used as the method for detecting the current position, but the present invention is not limited to this. For example, the mobile phone may receive its position information from a nearby base station or beacon.

[0025]

According to the present invention, the location of the calling party can be known before the mobile telephone device of the called party answers the incoming call.
The called party can answer the incoming call with reference to the location of the calling party.
