Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a route guidance system using a simplified mobile telephone.

[0002]

2. Description of the Related Art Hitherto, in the case of providing road guidance by telephone, in most cases, an address of a current location or a building serving as a landmark is transmitted to a partner to let the other person decide.

[0003] In a car or the like, a navigation system using a GPS device is employed, but there is a drawback in terms of carrying.

[0004]

As described above, when providing directions by telephone, it is necessary to judge the position from the surrounding situation, there is a problem in terms of accuracy, and in a place where there is no public telephone. There was a problem that there was no way to contact them if they got lost.

Accordingly, an object of the present invention is to provide a route guidance system using a simplified mobile telephone that can provide accurate route guidance at any place.

[0006]

In order to solve the above problems, a route guidance system using a simplified mobile phone according to the present invention comprises a simplified mobile phone and a GPS receiver connectable to the simplified mobile phone. And displays the data measured by the GPS receiver on the display unit of the simplified type mobile phone, and displays the distance to the communication partner and the direction thereof based on the position data transmitted from the communication partner. It is provided with a function of causing

[0007] According to the above-mentioned route guidance system, since the simple type mobile telephone and the GPS receiver are combined, it is portable and can know the location of each other's communication partner accurately.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a guide system using a simplified mobile telephone according to an embodiment of the present invention will be described with reference to FIGS.

That is, as shown in FIG. 1, the guide system in the present embodiment is a simple type mobile telephone (PH).
The mobile phone 1 includes a GPS receiver 3 connected to a data communication port 1 a of the mobile phone 1 via a signal line 2.

Of course, the GPS receiver 3 has an antenna (not shown) for receiving radio waves from GPS satellites, and the mobile telephone 1 has a GPS.
A calculation unit (not shown) is provided which can display the position data input from the receiver 3 and calculates the distance to the communication partner and its direction based on the position data sent from the communication partner. The calculation results are displayed on the display unit (monitor) 1b.

Next, a communication procedure between the mobile telephones 1 connected to the GPS receiver 3 will be described with reference to FIG.
As shown in FIG. 2, a mobile telephone 1 (1
A, 1B) perform wireless communication with a base station (hereinafter, referred to as a PHS base station) 4 (4A, 4B) of each of the mobile telephones 1A, 1B, and communicate with each of the PHS base stations 4A, 4B. Are connected by an ISDN line 5, for example.

In the communication procedure between the two mobile telephones 1A and 1B, one mobile telephone 1A calls the other mobile telephone 1B, and the other mobile telephone 1B sends a request to transmit a received signal and location data. And the location data is sent from one of the mobile telephones 1A, and after confirmation of reception, the other mobile telephone 1B sends the location data to the one mobile telephone 1A.
, There is a request to transmit position data, and after confirmation of reception, voice communication is performed.

In the above configuration, for example, when the party provides guidance for the party, the party calls the party. Then,
You and the GP connected to your mobile phone 1
The S receiver 3 measures each position.

When the two parties start communication by telephone, as described above, one of the mobile telephones 1 instructs the other mobile telephone 1 to send its position data and the other mobile telephone 1 transmits the position data. 1 also requests transmission of the position data of one mobile telephone 1.

That is, when the communication is started, the position data of each mobile telephone 1 is sent to the other party, and the distance and the direction of the other party are calculated in each mobile telephone 1 to display each. Displayed in the section 1a.

Therefore, when the mobile telephones 1 are connected to each other, the position of the other party can be instantaneously and accurately known. As described above, the distance and the direction between the communicating parties are obtained based on the position data from the GPS receiver. Therefore, even if there is an error in the GPS data, the mutual position data has the same error. Is included, the data of the distance and the direction obtained from the difference between the two data is not affected by the error.

By the way, in the above embodiment, 2
Although the case where two mobile telephones are used to indicate the distance between two persons and the directions of each other using two mobile phones has been described, for example, if a user wants to find a predetermined destination such as a tourist spot or a store, If the location data (GPS data) is stored in the telephone at the destination side and the location data is sent out when a communication is received, a tourist or a person searching for the destination can be used. It is possible to receive communication for route guidance only from.

In addition to the above-described route guidance, when notifying a meeting place between individuals, notifying a place where an emergency has occurred, or measuring a distance between athletes such as a marathon, This navigation system can also be applied to navigation such as walk rallies.

[0019]

As described above, according to the structure of the present invention, a simple and accurate navigation system can be obtained by combining a simple type mobile telephone and a GPS receiver.

[0020] That is, since the positions of each other can be confirmed with a portable device, the location of the person holding the simplified mobile telephone can be quickly known, and the person who is likely to be lost should have it. By doing so, it is possible to prevent missing, and by placing the bag in a bag or the like, it is possible to track the whereabouts of the bag.

In a sightseeing spot or the like, by storing the position data in the telephone at each base, easy and accurate road guidance can be performed.
