Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a location information service system for notifying a calling terminal (or a calling terminal) of a calling terminal (or a calling terminal) such as a public telephone from a location center to a calling terminal or a called terminal (or a called terminal). In particular, the present invention relates to a location information service system that can be applied when a business operator that operates a switching network is different from a business operator that installs and operates a transmitting terminal and a location center.

[0002] The present invention also relates to a transmitting terminal and a location center in such a location information service system.

[0003]

2. Description of the Related Art In a conventional system for providing location information of a calling terminal, location information is searched for from a telephone number of the calling terminal obtained by a caller ID notification function at a called terminal, or once issued from the calling terminal. Then, the location information is retrieved from the telephone number or the like of the calling terminal in the relay server that relays to the called terminal, and the positional information is provided to the called terminal.

[0004] Further, as an example of the prior art, as a service for providing location information such as the address of a caller to a callee,
A place-of-origin introduction service has been proposed for recipients of special telephone numbers such as police and fire lines (Japanese Patent Laid-Open No. 08-204).
835). In this service, the center obtains location information using the telephone number or terminal ID of the calling terminal of the caller,
Provide location information to the called party.

Japanese Patent Application Laid-Open No. 08-204841 discloses a public telephone location information system in which a caller can use a public telephone to notify his / her current location to the other party, and the caller himself can also obtain current location information. Have been. In this system, a caller transmits the telephone number and identification code of a public telephone to a base station (center), and the base station searches for location information based on the information transmitted from the caller, and receives the search result as a receiving station. Send to Examples of location information include location names,
A map display is included.

[0006] Also, by using the caller ID notification service started in recent years, it is possible to know the telephone number of the caller even outside the switching network, so that the telephone number and location information related to the telephone number can be obtained. A database or the like that associates the information with the sender can be constructed to provide the location information of the caller.

[0007] On the other hand, for the smooth operation of the location information service, it is considered that not only the appropriate information desired by the user can be provided, but also an appropriate service charge is generally required. Further, in order to appropriately charge a service fee, information security technology such as improvement of confidentiality of information related to a service and prevention of falsification of information becomes important.

As a method for charging a location information service in the prior art, for example, according to the invention described in Japanese Patent Application Laid-Open No. H10-326075, a digital public telephone compatible with an IC card is used, and a store near the public telephone is used. In the method of providing a destination guidance service, a call charge when dialing a service center from a public telephone is settled from an IC card or cash.

[0009]

However, in the above-mentioned conventional system for retrieving location information at a receiving terminal, if the telephone number of the transmitting terminal is private / not notified, the telephone number is used to retrieve the location information. There is a problem that can not be used.

[0010] In a system for retrieving location information at a relay server, the relay server needs a function of relaying a telephone call, and requires two telephone calls.

Regarding the position information, the fire department (119)
No.), police (110), etc., but there is no charge for providing location information, and inquiries about location information can be made only when the receiving terminal uses these special numbers.

Further, as can be seen from the above description of the prior art, when the terminal ID of the caller's calling terminal, for example, the telephone number can be known, by constructing a position information database using the telephone number as an index. In addition, it is possible to provide location information on the installation location of the calling terminal regardless of inside or outside the switching network. However, the telephone number of the calling terminal is generally information that the called party cannot know unless the caller ID notification service is used.
There are many subscriber terminals that keep their phone numbers private or private. Furthermore, the telephone number is kept secret from the public telephone.

Accordingly, a first object of the present invention is to provide a location information service system for notifying the originating terminal or the receiving terminal of the installation location of the originating terminal while maintaining the confidentiality of the telephone number of the originating terminal. .

[0014] A second object of the present invention is to provide a location information service system that can charge a service usage fee to a calling terminal when using location information.

[0015] A third object of the present invention is to provide a location information service system with high information security.

A fourth object of the present invention is to provide a location information service for notifying a receiving terminal of location information obtained by a transmitting terminal from a location center.

Another object of the present invention is to provide a location information use method, a transmitting terminal, and a location center in the location information service system.

[0018]
