Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication system for carrying out conversational communication between a plurality of IP networks.

[0002]

2. Description of the Related Art When conversation communication is performed between communication terminals managed by an IP network via the IP network, the calling terminal among the communication terminals is unique to a business operator who manages the IP network in advance. The connection information necessary for conversational communication, which is determined based on the numbering system set in, is transmitted.

[0003] Note that an operator who manages an IP network illegally accesses a communication terminal that is not managed on the IP network and requests a connection for conversational communication from a communication terminal that is managed on the IP network. Need to be blocked.

Therefore, a system is provided for permitting access only to the communication terminal to which the business operator has transmitted the connection information necessary for the conversational communication in advance, for security.

[0005]

Since the number system for determining the connection information necessary for the conversational communication is uniquely set by the operator managing the IP network, the number system is made consistent among a plurality of IP networks. Do not mean.

Therefore, the connection information previously transmitted to the calling terminal by the IP network managed by the calling terminal is connected to the partner communication terminal managed by an IP network different from the IP network. , The connection is rejected, and conversation communication cannot be performed.

In order to perform conversational communication between different IP networks, it is necessary to create a unified standard of the above numbering system and send connection information accessible between a plurality of IP networks determined by the unified standard to a transmitting terminal. Good.

However, in order to introduce the above-mentioned unified standard, it is necessary to invalidate the connection information based on the existing number system and to transmit the connection information based on the new number system based on the above unified standard. It is not easy to introduce because it takes time and money.

In view of the above problems, it is an object of the present invention to provide a communication system capable of conversational communication between a plurality of IP networks.

[0010]

In order to solve the above problems, a communication system according to the present invention is necessary for conversation communication between a plurality of IP networks and each communication terminal managed by each IP network. An IP network that includes a database created by collecting connection information, and uses the communication terminal managed by a predetermined IP network as a calling terminal and is different from the IP network that manages the calling terminal from the calling terminal. When receiving a request for conversational communication to the partner communication terminal managed by the sender terminal, the connection information necessary for conversation communication with the partner communication terminal is sent from the database via the IP network where the sender terminal is managed. It is characterized by comprising a transmitting means for transmitting to.

With this configuration, it is possible to acquire the connection information necessary for the conversation communication transmitted to each communication terminal based on the existing number system, and use this connection information to obtain another IP.
Since the network can be accessed, conversational communication can be performed between a plurality of IP networks.

Further, in the communication system according to the present invention, among the respective communication terminals managed by the plurality of IP networks, a predetermined communication terminal is used as a conversation communication transmission terminal, and the transmission terminal is managed from the transmission terminal. When a conversational communication request is made to a partner communication terminal that is managed by an IP network different from the IP network in use, the partner communication terminal that made the conversational communication request is requested in response to this conversation communication request. From the database created in the managed IP network, the sending terminal manages the connection information necessary for conversational communication with the partner communication terminal.
It is characterized by comprising a transmitting means for transmitting to the transmitting terminal via the P network.

According to this configuration, the connection information is acquired from the IP network for each request for conversational communication, so that it is not necessary to create a database in advance.

The information necessary for connecting to the other party's communication terminal from which the calling terminal makes a request for conversational communication is:
Since it is determined based on the number system that is independently set by each business operator that manages the IP network, there is a possibility that duplicate numbers are assigned to different communication terminals.

Therefore, regardless of whether the IP networks managing the communication terminals are the same or different, if the counterpart communication terminal is specified by the mail address uniquely assigned to each communication terminal, the above duplication problem does not occur.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 is a communication system according to the present invention. Communication system 1 is a business operator 2
Is connected to the IP network 21 managed by the company and the IP network 31 managed by the business operator 3 via the Internet.

In this embodiment, a communication terminal managed by the IP network 21 is called a transmission terminal 22 and I
A communication terminal managed by the P network 31 is referred to as a partner communication terminal 32. In this embodiment, the calling terminal 22 is assumed to be a general fixed telephone or a mobile telephone, but it may be an IP telephone or a personal computer having a telephone function. The partner communication terminal 32 is specifically an IP telephone having an IP address or a personal computer having a telephone function.

When a mail requesting conversational communication with the partner communication terminal 32 is sent from the calling terminal 22 via the general telephone network, the mail is sent via the gateway 23 to the IP.
It is sent to the network 21.

When requesting conversational communication from the other party communication terminal 32, in order to identify the other party communication terminal 32, it is necessary to identify the other party communication terminal 32 with unique data regardless of the IP network. In the present embodiment, the partner communication terminal 32 is specified by the mail address. Therefore, the sending terminal 22 sends at least the mail address of the partner communication terminal 32 in the mail requesting the conversational communication.

In the IP network 21, the sending terminal 22
The gatekeeper 24 determines whether or not the partner communication terminal 32 specified by the email address is a communication terminal managed by the IP network 21. The other side communication terminal 32 is I
When it is determined that the communication terminal is not managed by the P network 21, the above-mentioned conversation communication request is made to the gatekeeper 11 of the communication system 1.

The gatekeeper 11 determines in which IP network the partner communication terminal 32 specified by the request for conversational communication is a communication terminal. This judgment is based on the above e-mail address as a clue for each IP
This is performed by searching the address database 12 created by collecting connection information required for conversational communication at each communication terminal managed by the network.

In the present embodiment, the connection information required for conversational communication at each communication terminal managed by each IP network is the address database 25 managed by the IP network 21 and the IP network 31.
The connection information stored in the address database 35 managed by is applicable.

The gate keeper 11 sends back the connection information 13 necessary for conversational communication with the partner communication terminal 32 from the address database 12 to the calling terminal 22 by mail via the IP network 21.

The connection information 13 includes at least the mail address of the partner communication terminal 32, the telephone number of the partner communication terminal 32, the telephone number of the access point of the partner communication terminal 32, and the member number of the calling terminal 22.

When the originating terminal 22 inputs the connection information 13, it is confirmed that the gatekeeper 34 of the IP network 31 is a connection request for conversational communication with the partner communication terminal 32, and the partner communication terminal 3 via the gateway 33.
Connected to 2.

By the way, the connection information 13 is transmitted from the calling terminal 22 in response to a conversation communication request from the partner communication terminal 32.
IP network 3 that manages the partner communication terminal 32
It is also possible to transmit from the database 35 created in 1 to the calling terminal 22 via the IP network 21 in which the calling terminal 22 is managed. In this case, it is not necessary to create the database 12 in advance.

The originating terminal 22 and the other party's communication terminal 32
When the connection of the above-mentioned conversational communication with is started, the gatekeeper 11 manages the time until the end of the connection. This connection time data is used for each gatekeeper 24 and gatekeeper 3 in order to be used for billing settlement based on the contract between the operators 2 and 3.
4 is transmitted.

[0028]

As is apparent from the above description, the present invention is based on the existing numbering system in which conversational communication between a plurality of IP networks is uniquely set by the operator managing the IP networks. Since the determined connection information is used, it can be realized without incurring time and cost. Also, if a connection request is first made from the calling terminal and connection information is acquired, conversational communication with the partner communication terminal is possible by simply inputting the connection information thereafter.
Conversational communication can be easily performed between networks.
