Next, the operation of this embodiment will be described in more detail with reference to FIG.

First, when making a call with the caller terminal 1,
GPS signal 11 is received from GPS satellite 4 (see),
The location information from the GPS built-in portable information terminal 5 is stored in the telephone terminal 6
Is transmitted to the receiver terminal 2 via the network 20 as the sender-side position information 13 (see).

At this time, selection of a receiver vicinity map display area displayed as a position search result of the GPS built-in portable information terminal 5, that is, whether only a map around the receiver should be displayed or not, including the current position of the sender. It is assumed that it is possible to select whether to display the route to the receiver or to display only the map around the sender.

Next, the receiver terminal 2 that has received the telephone call from the telephone terminal 6 receives the GPS signal 12 from the GPS satellite 4 (see), and the caller side position information 13 of the caller terminal 1.
And the receiver as the location information of the receiver terminal 2 itself.
The caller location information 14 is transmitted to the location search server 3 in the service provider via the network 20 (
reference).

The location search server 3 in the service provider, based on the location information of each of the sender terminal 1 and the receiver terminal 2, stores a map of the area selected by the above operation on the sender terminal 1. It is sent out via the network 20 as the sender's surrounding map information 15 (see).

At this time, in the route display connecting the current positions of the sender terminal 1 and the receiver terminal 2, if both are separated by a predetermined distance or more, it is necessary to fit them on one screen of the GPS built-in portable information terminal 5. Since the scale of the map is too large, a message indicating that displaying the map is meaningless is displayed, and only the map around the current position of the receiver terminal 2 is displayed. After the end of these operations, a map of the position search result is displayed on the sender terminal 1 (see).

It is also possible for the caller terminal 1 to move and enlarge / reduce the map while looking at the map of the search result. In this case, the position search server 3 and the caller terminal 1 in the service provider are provided each time. Information line 1 directly connected between
6 (see reference).

In this case, it is not necessary to connect the sender terminal 1 and the receiver terminal 2 again.

In the location search server 3 in the service provider, the sender terminal 1 and the receiver terminal 2 which are users
By collecting the charge for the location search service by using the charging system from, and providing the above-mentioned service to the user, business development will be achieved.

As described above, simply making a call to a person having a telephone connected to the portable information terminal 5 with a built-in GPS,
It is possible to perform a position search of a destination limited to those registered on a town page or the like, and to grasp a current position of a partner not registered on a town page or the like or a moving partner.

[0036] Also, the moving receiver itself has GPS information.
By using the telephone terminal 8 connected to the built-in portable information terminal 7, it is possible to search for a route from the current position to the partner between the mobiles.

The GPS built-in portable information terminals 5 and 7 can be connected to both mobile (mobile phone, PHS) and fixed telephones.

Therefore, the following advantages can be obtained as compared with the conventional method.

In the case of a mobile telephone (mobile phone, PHS), the current position of the other party or the shortest route to the other party can be displayed between the mobile users, which is very convenient, for example, for meeting in the city. .

Also, a location search service for mobiles using PHS (a PHS terminal is provided for children and the elderly,
Although there is a service that can grasp the approximate position), this is a 50-meter radius centered on the position of the nearest PHS base antenna.
The accuracy is roughly within the range of 0 m or more.
Compared with S, in the present invention, the accuracy of the GPS has an error of several tens of meters, so that a position search with extremely high accuracy can be performed. Moreover, PHS still covers only urban areas, and in this regard, the use of GPS can cover all parts of the country and anywhere in the world.

As another application, there is a system for managing the allocation of taxis using the mobile information terminals 5 and 7 with a built-in GPS. In this case, a dedicated system must be purchased separately for the managing side. Also in this regard, the present invention can be provided by a general service such as the I-mode.

In addition, even if the destination is not registered in the town page or the like for a fixed telephone, the location of the destination can be searched only by knowing the telephone number, so that registration to the town page or the like is unnecessary. Thus, it is possible to quickly respond to a change in telephone number.

In many cases, only the representative telephone number is registered on the town page or the like in many cases. Therefore, even when searching for a partner having offices scattered in a plurality of locations, only the location of the representative number can be searched. However, in the present invention, it is possible to search for the location of the visited office that is not registered in the town page or the like.

As described above, according to the present invention, by performing a location search service using a telephone with a GPS function, the location of any other party can be ascertained as long as the telephone number of the other party is known. .

FIG. 2 is a block diagram showing a second embodiment of the GPS connection position search method according to the present invention.

In FIG. 2, components corresponding to those shown in FIG. 1 are denoted by the same reference numerals or symbols, and description thereof is omitted.

It is sent to the location search server 3 in the service provider (see).

The location search server 3 in the service provider sends a map of the surrounding area to the sender terminal 21 based on the receiver location information 24 of the receiver terminal 2 so that the receiver peripheral map information 2
5 (see).

At this time, the sender terminal 21 and the receiver terminal 2
In the display of the route connecting the current positions of the mobile information terminals with the GPS built-in
Since the scale of the map is too large to fit on one screen, a message indicating that displaying the map is meaningless is displayed, and only the map around the current position of the receiver terminal 21 is displayed. After the end of these operations, a map of the position search result is displayed on the caller terminal 21 (see).

It is also possible for the caller terminal 21 to move and enlarge / reduce the map while looking at the map of the position search result. In this case, the position search server 3 and the caller terminal in the service provider are used each time. The transmission processing is performed by an information line 26 directly connected to the communication device 21 (see).

[0054]

As described above, according to the GPS connection position search method of the present invention, even a person who is not registered in the database can be searched, and even in the case of a fixed telephone, there is no need to pre-register to a town page or the like. Therefore, there is an effect that a telephone number can be changed or a new subscriber can be promptly dealt with.

Further, even when the telephone number registered on the town page or the like is a representative number, the present invention is not limited to the search for the position of the representative number.

Further, as compared with the position search service using the PHS, there is an effect that use of the GPS can significantly improve the accuracy.
