Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention records an Internet telephone terminal identification processing method for identifying a connection partner terminal during real-time data communication in a LAN (Local Area Network) by Ethernet or the like, and records the apparatus and its program. It relates to a recording medium.

[0002]

2. Description of the Related Art A LAN based on Ethernet or the like is a network for performing communication by packet data.
Originally, the network was not suitable for real-time data communication such as voice. However, in recent years, an application of the type called an Internet telephone for exchanging voice data packets in a LAN in real time has begun to appear.

[0003] When constructing a LAN by Ethernet or the like, it is common to construct a network by the TCP / IP protocol. At this time, the terminal connected to the network is usually identified using a terminal identifier called an IP address.

[0004] When an IP address is represented by a decimal number,
xxx. xxx. xxx. xxx is represented by four three-digit numbers (xxx is a number from 0 to 255) separated by “.”.

FIG. 22 shows an example of an IP address. As can be seen from the figure, for example, terminal A has "12
9.060.010.010 "(in FIG. 22, for simplicity, the leading zero of every three digits is omitted and is set to" 129.60.110.10 ").

[0006]

In order to specify a connection partner in the above-described Internet telephone or the like, it is necessary to specify the IP address of the partner terminal directly or the e-mail address of the partner when making a call. Is a common method.

FIG. 23 shows an example of an electronic mail address.
However, when using an IP address to specify a connection destination, a general user needs to memorize up to 12 digits of an IP address that is unfamiliar to ordinary users, and must input this. There was a problem that it was difficult.

[0008] The IP address is a number that is important in the system and is a number that one does not want to disclose to the outside of a different network. There was a problem that it was necessary to make it public.

[0009] Further, when the connection destination is designated by an e-mail address, it is usually necessary to input a fairly long alphabetical address, and a keyboard is required for inputting, so that the terminal is limited to a personal computer. It cannot be input from a simple device such as a telephone or FAX,
There was a problem.

Further, in order to simplify the input at the time of connection, a method of registering the name of the other party and the IP address of the other party in advance in a communication application in the terminal (personal computer) and referencing it when making a call. Is also used.

However, in order to perform this method, it is necessary that the terminal has a high-performance device such as a personal computer having an alphabet keyboard and capable of registering data therein, and a keyboard such as a telephone or a facsimile. However, there is a problem that input cannot be performed with a simple device that does not have a password.

According to the present invention, in order to solve the above-mentioned problems, in real-time communication in a LAN, when a call is made to a partner terminal, a number which can be easily remembered by a person such as a telephone number is input. , The designation of the partner terminal is simplified, and the designation of the partner terminal is enabled with the IP address hidden from the outside. Even with a simple input device such as FAX, it is possible to input the designation of the partner terminal, and it is possible to assign a single terminal management number to multiple terminals and process using port numbers The purpose is to.

[0013]

According to the present invention, a terminal identifier (terminal management number) such as a telephone number different from an IP address is provided for a terminal (client terminal) in a network, and this is managed. A server terminal for networking in the network.

Since it is considered that a plurality of server terminals exist in the network, a numeric identifier (server management number) for identifying the server terminal itself is provided.

FIG. 1 shows a configuration in which an identifier is provided in the case of the present invention. For clarity in comparison with FIG. 22, for example, a terminal management number "2001" is given to a terminal A to which an IP address "129.60.10.11" is given. Then, the server management number + terminal management number is set as a telephone number in the LAN.

The server terminal has means for describing the terminal management number and the IP address of the terminal corresponding to the terminal management number.
Has a means to return the address. As a means for describing the terminal management number and the IP address of the terminal corresponding to the terminal management number, a terminal management table as shown in FIG. 2 is exemplified.

The server terminal has means for describing the server management number and the IP address of the server terminal corresponding to the server management number, and has means for returning the server management number of the corresponding server terminal in response to an inquiry by the server management number. . As means for describing the server management number and the IP address of the server terminal corresponding to the server management number, a server management table as shown in FIG. 3 is exemplified.

As the server terminal, a network IF
General PCs and workstations are available. A terminal (client terminal) on the side of making an Internet call has means for inputting a telephone number in the LAN. It also has a means for storing the IP address of the default server terminal which first makes an inquiry when making a call. At the time of calling, before the call is made to the partner terminal, the entered LA is input to the default server terminal.
It has means for inquiring about the IP address of the partner terminal using the telephone number within N.

Also, means for recording the telephone number in the LAN called in the past and the IP address corresponding to the telephone number, and the telephone number recorded in the LAN in the own device and the corresponding information before inquiring the server at the time of the call. There is a means for referring to the IP address and a means for directly calling the partner terminal by omitting the inquiry to the server terminal if the call destination at that time is recorded.

Further, the server terminal is provided with one master server for managing all servers of the network concerned. The master server has means for distributing the information of the server management number in its own terminal to the subordinate server terminals. Each server terminal has means for receiving the information sent from the master server, and means for changing the server management information of its own terminal to the contents of this information.

At the time of making a call, a telephone number in the LAN including a server management number and a terminal management number is input from the client terminal. As the client terminal, a personal computer with a network IF, a general analog telephone or FA
A terminal connection device (TA device) for connecting X or the like to a network is conceivable. Before calling the destination terminal, the client terminal queries the server terminal for the IP address of the destination terminal using the input telephone number in the LAN. The server terminal that has received the inquiry performs a search within itself, and returns the IP address of the terminal. The client terminal makes a call to the terminal of the received IP address, and starts communication after connection.

Thus, the client terminal is able to
By inputting a telephone number such as a telephone number within N, a partner terminal can be designated, and the partner terminal can be designated by a simpler method than an IP address.

As a method for identifying a terminal, a LAN
By using the internal telephone number, it is possible to hide the IP address from the user. Also, the telephone number in LAN is
Since it is composed only of numbers, it is possible to use a simple input device such as a telephone or a facsimile as the client terminal.

After the communication is completed, the telephone number in the LAN from which the call was made and the corresponding IP address are recorded. Next, when making a call, first, referring to the record of the telephone number in the LAN in the own device and the corresponding IP address, if the call destination at that time is recorded, the inquiry is omitted.
Place a call directly to the other terminal. As a result, it is possible to reduce the time required for connection at the time of calling.

Even when the telephone number in the LAN of each client terminal is changed, only the setting of the server terminal needs to be changed, and the trouble of changing the setting of each client terminal can be omitted. .

Further, when there is a change in the server terminal in the master server, by distributing this change information to other server terminals, it becomes possible to share correct server management information among the servers.

FIG. 4 shows a mode in which the master server distributes data to respective server terminals under the master server. In the case of FIG. 4, the master server includes server terminals A, B,
The change information is distributed to the server terminal C, and each server terminal stores it in the server management table.

The LAN telephone number and the corresponding terminal I
As means for describing the correspondence between the P address and the channel number, a terminal management table shown in FIG. 17 is exemplified.

FIG. 18 shows a sequence example at the time of calling. At the start of communication, the terminal connection device TA in the IP network
1 from the calling Internet telephone terminal (telephone 3) connected to another terminal connection device TA in the IP network.
In order to call the Internet telephone terminal (telephone 4) connected to 2, the user inputs the LAN telephone number allocated to the called Internet telephone terminal (telephone 4). The calling Internet telephone terminal (telephone 3) receives the entered LA.
The N telephone number is transmitted to the connected terminal connection device TA1.
The terminal connection device TA1, which has received the LAN telephone number,
An inquiry packet including the LAN telephone number is transmitted to the AN telephone number server. IP of the LAN telephone number server
It is assumed that the address is set in advance in the terminal connection device TA1.

The LAN telephone number server receiving the inquiry packet searches the terminal management table in the server for the LAN telephone number in the inquiry packet, and obtains the target IP address and the channel number. The LAN telephone number server transmits a reply packet including the acquired IP address and channel number to the terminal connection device TA1 that has made the inquiry.

Upon receiving the reply packet, the terminal connection device TA1 of the inquiry originates the IP connection described in the reply packet.
An outgoing call packet including the channel number to be called is transmitted to the terminal (TA2) at the address. Further, since the terminal connection device TA1 recognizes which channel number of the Internet connection terminal (telephone 3) of the caller is connected to which channel number of its own terminal connection device TA1, the terminal connection device TA1 transmits the voice packet data according to the channel number. Select the port number used for reception. The selected receiving port number is also included in the outgoing call packet. The called terminal connection device TA2 that has received the calling packet recognizes the Internet telephone terminal (telephone 5) to be called by the channel number included in the received calling packet, and the corresponding called Internet telephone terminal. Ring the terminal (telephone 5). When the receiving operation is performed on the telephone 5, the terminal connection device TA2 transmits an incoming call reception packet to the terminal connection device TA1 on the calling side. Since the called terminal connection device TA2 recognizes which channel number of the terminal connection device TA2 the incoming telephone is connected to, the terminal connection device TA2 selects a port number used for receiving voice packet data according to the channel number. I do. The selected reception port number is included in the incoming call reception packet.

[0070] Both terminal connection devices are thus:
Each other can tell the port number used for receiving the voice data packet, and receive the data correctly. In addition, since the voice data packet sent to the port number is also recognized as to which channel number of the terminal connection device is addressed to the telephone, the voice data can be transmitted to the correct Internet telephone terminal (telephone). .

As described above, the Internet telephone terminal and L
The AN telephone number is managed by the IP address and the channel number of the terminal connection device, and each terminal connection device changes the port number for voice data packet reception for each channel number, and both terminal connection devices receive the voice data packet. By notifying the port numbers to be used in advance in advance, it becomes possible to correctly identify a plurality of Internet telephone terminals connected to one terminal connection device and perform voice communication. As a result, one terminal connection device having one IP address can manage a plurality of Internet telephone terminals.

Also, for a device such as a personal computer which becomes an Internet telephone terminal by itself, the channel number is always set to 1 in the terminal management table. With this setting, it is possible to incorporate an Internet telephone terminal such as a personal computer other than the terminal connection device into the LAN telephone number system.

When the number indicating the input of the IP address, the IP address of the terminal connection device TA2, and the channel number of the telephone 5 are directly input from the telephone 1 connected to the terminal connection device TA1, the LAN telephone number is used. No inquiry is made to the server, and the channel number of the telephone 5 to be called and the own terminal connection device TA2 are directly sent to the terminal connection device TA2.
1 transmits a call packet including a reception port number used for transmitting voice data to the telephone 1. After the receiving terminal connection device TA2 receives the outgoing call packet, the operation is the same as when the LAN telephone number server is used.

As described above, it is determined whether the number input by the telephone connected to the terminal connection device is a LAN telephone number or an IP address. If the number is an IP address, by directly calling the other party's Internet telephone terminal, LAN
Even if there is no telephone number server, this terminal identification method can be used.
