Abstract

PROBLEM TO BE SOLVED: To select a domestic or overseas gateway and to establish a telephone call via its respective gateway by deciding from the inputted telephone number of the other party, whether a connecting destination gateway is for domestic or overseas. SOLUTION: An internet telephone terminal inputs a number starting with a normal area code number, when the other party is domestic and inputs a number starting with a international telephone call identification number, when the other party is in overseas at the time of making a call. Next, an IP address inquiry packet of a connecting destination gateway, including the number of the other party and an one's country number, is sent to a gateway address server for gateway address management to check whether it is an international identification number of the country code number. It is decided to be an overseas gateway when it is the international identification number, it is decided to be a domestic gateway when it is not, and when it is decided as the overseas gateway, a domestic destination number of the other party's country is extracted from a part of the number other than the international identification number and a country number, and an long-distance area prefix of the country is added.

FIG. 27 shows an example of the operation of the gateway.
This figure shows how Internet gateway software on a personal computer connects to a telephone in the general telephone network using a gateway.

That is, when a call packet is issued from the personal computer to the gateway using the IP network, the gateway receives the packet and calls the telephone network. As a result, the called telephone rings and a telephone call is established when the telephone is hooked off. In response, the gateway sends an incoming call acceptance packet to the personal computer, and when the personal computer receives the packet, the gateway sends an audio data packet. Communicate using analog audio signals.

When there are a plurality of gateways in the IP network, it is important to select an appropriate gateway according to the telephone number of the other party to be called. A gateway address table that has a gateway management table (FIG. 28) for managing the correspondence with the gateway IP address corresponding to the area code area, and returns an appropriate gateway IP address according to the area code of the other party's telephone number. To solve the problem.

FIG. 29 shows a configuration having a gateway address server. There is a gateway between the IP network and the general telephone network.
If a gateway address server is connected to the network
It is assumed that the connection is made with the P address “129.60.10.1”. It is assumed that the gateway address server has a gateway management table as shown in FIG.

The illustrated Internet telephone terminal calls the gateway address server (assumed in advance) using the IP address "129.60.10.1" and corresponds to the general telephone network to which the general telephone to which the user wants to transmit is connected. Gateway's IP address, for example, "129.60.30.1
Ask them to tell you "0."

This technology is disclosed in Japanese Patent Application No. 9-34 filed by the applicant.
No. 764 is disclosed in the patent application. However, this method can cope with the case where the gateway is located in Japan, but cannot deal with the case where the gateway is located outside the country and an international connection is made with the gateway outside the country. was there.

FIG. 30 shows a configuration in the case of connection with a gateway outside the country. In the figure, the configuration surrounded by a dotted line as "Japan" corresponds to the system shown in FIG. 29, and the configuration surrounded by a dotted line as "USA" is a configuration in the United States. The composition in the United States can be considered to be almost the same as the composition in Japan.

In FIG. 30, a call indicated by a bold line marked with “○” can be made as described with reference to FIG. 29, but a call indicated by a bold line marked with “x” can be called. The call cannot be made because the other party's gateway is not a gateway in Japan.

Although there is no established dialing method for calling another country's telephone in an Internet telephone, the method is as close as possible to the existing international telephone dialing method in consideration of the user's usage. It is thought that it is necessary to consider a realization method.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a method of making a call to a general telephone network via a gateway, based on the input telephone number of the other party and the destination gateway. Is a domestic or foreign country, if it is domestic, select a domestic gateway to establish a call with a domestic telephone, and if it is a foreign country, select a foreign (other country) gateway and select a foreign It is intended to be able to establish a call with a foreign telephone via a (national) gateway.

It is another object of the present invention to provide a method for designating the other party's telephone number at that time by using the same dialing procedure as a dialing method for an existing international call.

[0015]

In the present invention, it is assumed that a plurality of the aforementioned gateways are arranged in a certain area in an IP network such as the Internet.

FIG. 1 shows a system configuration to which the present invention is applied. In the IP network, a gateway address server for managing a gateway address is arranged in addition to the gateway. Examples of the Internet telephone terminal include a general-purpose computer such as a personal computer and a WS in which Internet telephone software is installed, and a device (a telephone adapter) for directly receiving a general telephone terminal into an IP network. Further, since a connection form of gateway → gateway is also conceivable, the gateway itself is also regarded as an Internet telephone terminal.

The gateway address server includes means for recording the correspondence between the country code and the international call identification number in the country, means for recording the correspondence between the country code and the toll prefix in the country, Means for recording the correspondence between the domestic area code of the country and the IP address of the gateway corresponding to the area of the area code, the other party's telephone number transmitted from the Internet telephone terminal in the IP network, and the inquiring Internet terminal Receiving the IP address inquiry packet of the connection destination gateway including the country code of the destination, and searching within the own device based on the other party's telephone number and the country code in the received inquiry packet to appropriately connect Means for selecting the destination gateway, the IP address of the selected destination gateway, and the other party to which the gateway automatically originates the call Having means for reply reply packet and the inner phone number querying the Internet phone terminal.

[0018] Further, the Internet telephone terminal on the inquiry side stores means for storing the IP address of the gateway address server of the inquiry destination when making a call to the general telephone network via the gateway, means for setting the country code of the home country, Means for inputting the telephone number of the other party of the telephone network, means for transmitting to the gateway address server an inquiry packet of the IP address of the connection destination gateway based on the other party's telephone number and the country code of the home country, Means are provided for receiving a reply packet including the IP address of the connection destination gateway and the domestic telephone number of the other party automatically transmitted by the connection destination gateway.

According to the present invention, when a call is made, the other party's telephone number in the general telephone network is input at the calling Internet telephone terminal in the IP network. At this time, if the other party is in Japan, enter the domestic telephone number starting with the area code (including the area prefix) (for example, “04685”).
91111 "). If the other party is outside the country, enter the international call identification number + the other party's country code + the domestic destination number (excluding the toll prefix) in the same way as for a normal international call. If you do: "011
814685911111 "). Next, the Internet telephone terminal transmits an IP address inquiry packet of the connection destination gateway including the input destination telephone number and the country code of the home country to the gateway address server set in advance. It is assumed that the country code of the home country is set in the Internet telephone terminal in advance.

FIG. 2 shows an example of an IP address inquiry packet for asking an IP address of a connection destination gateway. The packet includes a command type indicating that the packet is an IP inquiry, the IP address of the own device, the other party's telephone number, and the country code of the home country.

The gateway address server, which has received the IP address inquiry packet of the connection destination gateway,
It is checked whether the first number of the other party's telephone number in the received IP address inquiry packet is the international call identification number of the country of the country code in the received IP address inquiry command. This check uses an international call identification number table.

FIG. 3 shows an example of the international call identification number table. The international call identification number table describes the correspondence between the country code of the country and the international call identification number of the country. As a result of the check, if the first number of the other party's telephone number in the IP address inquiry packet of the connection destination gateway is the international call identification number of the country code, the gateway is outside the country; otherwise, Judge as a domestic gateway.

As a result, if the connection destination is determined to be a gateway outside the country, the country code of the partner country following the international call identification number is obtained. Next, the domestic destination number of the destination country is extracted from the part of the destination telephone number excluding the international call identification number and the country code. However, this domestic destination number is not prefixed with the country's toll prefix. Also, the toll prefix is different for each country (eg, Japan = 0,
America = 1 etc.). So, in the extracted domestic destination number,
Add a country prefix for the country (for example, "468
→ 0468 ”). For this purpose, a toll prefix table is used.

FIG. 4 shows an example of a toll prefix table. The toll prefix table describes the correspondence between the country code of the country and the toll prefix of the country.

Next, the area code is extracted from the domestic telephone number of the partner country to which the area prefix is added. The IP address of the connection destination gateway is searched using the extracted area code. For this purpose, an area code table is used.

FIG. 5 shows an example of the area code table. The area code table describes the correspondence between the country code of the country and the IP address of the gateway corresponding to the area of the area code.

The IP address of the gateway is searched for from the country code and the area code of the partner country. In the reply packet and send it back to the inquiring Internet telephone terminal.

FIG. 6 shows an example of a reply packet. The packet describes a command type, a domestic telephone number to be called by the gateway, and an IP address of the gateway to be connected.

Upon receiving the return packet, the inquiring Internet telephone terminal transmits the IP address in the return packet.
A call packet including the domestic telephone number of the partner country in the return packet is transmitted to the gateway of the address.
The gateway receiving the call packet automatically makes a call to the telephone network of the home country with the domestic telephone number of the partner country in the call packet. When the called party's telephone number arrives, the gateway transmits a call acceptance packet to the inquiring Internet telephone terminal, and voice communication is started.

If the gateway is determined to be a domestic gateway, the area code table is searched immediately. Also in this case, since the country code of the home country is described in the inquiry packet, the IP address of the connection destination gateway is searched for the area code of the home country. As for the area code, in the case of Japan, since the area prefix is added from the beginning, the search is performed as it is. After the search, the IP address of the searched gateway and the telephone number including the area code (=
(Domestic telephone number) is included in the reply packet and sent back to the inquiring Internet telephone terminal.

[0031] The Internet telephone terminal that has received the return packet and inquired about is the IP telephone in the return packet.
A call packet containing the destination's domestic telephone number in the return packet is transmitted to the gateway of the address. The gateway that has received the call packet automatically makes an outgoing call to the telephone network of the home country with the destination's domestic telephone number in the call packet. When the called party's domestic telephone number arrives, the gateway transmits an incoming call reception packet to the inquiring Internet telephone terminal, and voice communication is started.

As a result, if the other party's telephone number is dialed from an international call identification number indicating a foreign country, a foreign gateway is selected and an Internet telephone call is made with a telephone on a foreign telephone network. A call can be established.

The gateway address server can be set up for each country. In this case, the gateway address server has a gateway address server selection table.

FIG. 7 shows an example of the gateway address server selection table. The IP address of the gateway address server selected for each country is described. The gateway address server determines whether the call is a domestic call or a foreign call within its own device. If the call is outside the country, the SV indicating the server is described in the column of the type of terminal or server, and the gateway address server of the partner country is used. It is returned in a return packet containing the IP address.

FIG. 8 shows an example of a return packet. The packet describes the command type, the domestic telephone number to be called by the gateway, the IP address of the gateway address server of the partner country, and the type of terminal or server. The Internet telephone terminal of the inquiry source receiving this transmits the IP address inquiry packet of the connection destination gateway again to the gateway address server of the partner country. The subsequent sequence is the same as in the case where there is one gateway address server.

Also, as the international call identification number, the operator number of the international telephone operator frequently used by the user is entered. Can be registered.

This function as a gateway address server can be provided locally in the Internet telephone terminal. In this case, it is possible to omit the inquiry to the gateway address server, perform a search in the own device, and immediately call the other gateway. As a result, the time required for connection can be reduced.
