Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone system and an exchange which enable each telephone terminal to acquire information on a geographical position of a telephone terminal to be connected.

[0002]

2. Description of the Related Art A conventional fixed telephone telephone number system is closely associated with a geographical location. That is, each telephone number is divided into a region code (area code) assigned to each prefecture and a plurality of regions, and a station code (city code) assigned to each region by further dividing the region.
And subscriber numbers in the region. In such a case, one telephone number corresponds to one telephone in principle, and its geographical position is within the management range of the same exchange even if it changes. Therefore, it was relatively easy to estimate the geographical position range of the connection destination from the telephone number.

[0003] However, in the case of a telephone number borne by the called party, a number is assigned to the telephone terminal regardless of its geographical position. For example, in the case of a designated area charging service (toll free (registered trademark) service), a dialed six-digit number starting with 0120 is sent from a caller to a computer via a transit exchange. The computer can change the destination of the received telephone number according to a normal telephone number time zone or day of the week. Similarly, even in various call centers, general fixed telephones, and the like, it is possible to change the destination according to the time zone and the day of the week. Even in this case, it is difficult for the caller to know the geographical position of the connection destination.

In recent years, new technologies such as a virtual private network (VPN), a personal telephone, and the like, which are one of intelligent network services, have been introduced into a switching network. Alternatively, telephones using the Internet line, telephones using the cable television (CATV) line, and the like have become widespread. Similarly, in these new technologies and new services, the geographical location may not correspond to the subscriber telephone number. Thus, even with a fixed telephone, it is difficult for a caller to directly know the geographical location of the connection destination.

On the other hand, in the case of mobile communications, the subscriber telephone number is independent of the subscriber's geographical location.

[0006] In a PHS (Personal Handy Phone System) or the like, there is a service for displaying a subscriber's own geographical position on a screen using a base station or GPS. However, there is no means for notifying the sender of the geographical location information of the connection partner.

[0007]

As described above,
In conventional telephone communication, a caller could not know the geographical location information of a connection destination. For this reason, the caller made a phone call in the near field, but actually received a call in a remote site and was sometimes charged unexpectedly. To avoid this problem, the caller and the callee
Japanese Patent Laid-Open No. 10-13612 discloses a technology that can set the charge sharing.
No. 6 discloses this. However, this technology is a technology limited to a case where a call made to a specific telephone number is received by a pre-specified subscriber telephone number, and the actual geographical position of any destination is obtained. It is not a technology that can be informed. In addition, it is necessary to pre-register telephone numbers and assignments, and the operation is complicated. Further, this publication discloses that information about billing is notified to a caller before a call is started.
However, the notified information is not information that allows the caller to know the location of the connection destination.

The present invention has been made in view of the above-mentioned circumstances, and has as its object to provide a system that allows a calling party to acquire geographical location information of a called party. It is a further object of the present invention to notify the calling side of the geographical location information of the receiving-side telephone terminal before the start of a call, so that the calling side can be used as a measure of billing.

[0009]

In order to achieve the above object, a telephone system according to a first aspect of the present invention is a telephone system comprising a plurality of telephone terminals, a plurality of exchanges, and a line network. In the system, each exchange receives a call request, identification information of a called-side telephone terminal, and a request for geographical location information of a called-side telephone terminal from a calling-side telephone terminal. Means for transmitting a connection request and a transmission request for geographical location information to the exchange via the network, and receiving location information from the terminating exchange via the network,
Means for notifying the calling telephone terminal, request receiving means for receiving a connection request and a request for transmission of geographical location information from the calling exchange via the circuit network, Means for calling the telephone terminal; and obtaining position information for obtaining geographical position information of the telephone terminal on the receiving side in accordance with the received request and transmitting the obtained geographical position information to the exchange on the calling side via the circuit network. Means, each phone, when making a call, to the exchange to which it is connected,
Means for transmitting an outgoing call request, identification information of the called-side telephone terminal, and a request for geographical location information of the called-side telephone terminal;
Means for receiving the geographical position information transmitted from the exchange on the receiving side and reporting the geographical position of the telephone terminal on the receiving side.

[0010] According to this configuration, the caller can acquire the geographical position information of the telephone terminal on the receiving side, so that it is possible to estimate the call charge.

[0011] The exchange may further comprise means for acquiring information indicating a geographical location of the calling telephone terminal. As a result, the relative positional relationship between the calling side and the called side can be indicated, so that it is possible to more easily estimate the call charge.

[0012] The exchange may further include a database storing a table for associating identification information of each telephone terminal with its location information. By searching this database, geographical position information corresponding to the identification information of each telephone terminal can be searched. Instead of searching for a database via an exchange or the like, a database provided directly is searched, so that information can be obtained quickly. Therefore, the time required from when the user makes a call request to when the user actually knows the geographical position information on the calling telephone terminal is reduced.

[0013] The exchange may further comprise means for setting a line in a call waiting state until receiving a call start signal of the telephone terminal, receiving the call start signal, and starting a call and charging. Thus, the user can also reject an unintended call before starting the call.

In order to achieve the above object, an exchange according to a second aspect of the present invention is an exchange that enables a transmitting telephone terminal to acquire information on the geographical location of a receiving telephone terminal. The exchange receives the outgoing call request, the identification information of the called telephone terminal, and the request for the geographical position information of the called telephone terminal from the calling telephone terminal, and sends the request to the called exchange. Means for transmitting a connection request and a request for transmission of geographical location information, means for receiving location information from the destination exchange and notifying the originating telephone terminal, and connection request and geography from the originating exchange. Request receiving means for receiving a request for transmission of target location information, means for calling a telephone terminal on the receiving side according to the received request, and geographical position information of the telephone terminal on the receiving side according to the received request. Sought, and sought geographical location information Comprising position information acquisition means for transmitting the signal side of the switch, and wherein the.

The user who has made the call request can know the geographical position information of the caller and the receiver on the calling telephone terminal, so that it is easier to set a rough estimate of the call charge.

[0017] The exchange may further include a database storing a table that associates identification information of each connected telephone terminal with its position. As compared with the case where a database is searched through an exchange or the like, the information can be quickly acquired because the search is for an internal database. Therefore, the time required from when the user makes a call request to when the user actually knows the geographical position information on the calling telephone terminal is reduced.

In order to achieve the above object, an exchange according to a third aspect of the present invention is characterized in that the exchange receives the call request from the calling telephone terminal and receives a predetermined call start signal until the call request is received. Means for setting the line to a call standby state, and means for setting the line to a call state when a predetermined call start signal is received after transmitting the position information to the calling telephone terminal, and further, a means for starting charging. , Is further provided.

According to this configuration, the user can know the geographical position of the telephone terminal on the receiving side before starting the actual call, so that the user can estimate the call charge or reject unintended connection. It is possible to do.
