[0005]

Conventionally, for example, when making a call from Mr. A to Mr. B, Mr. A finds the extension number used by Mr. B from the network configuration diagram such as a telephone directory, and the searched number is used. By dialing, the telephone of Mr. B's hand can be called and the communication between Mr. A and Mr. B can be carried out in response.

However, if Mr. B is not in the prescribed place, Mr. A cannot call Mr. B. Waiting for a message from Mr. B, or searching for Mr. B's destination and calling again. It will be. In other words, since the telephone communication such as PBX is performed using the extension number of the telephone as a keyword, the telephone with the extension number owned by Mr. B is B
There is a problem that you cannot communicate if you do not have him.

[0007] Recently, there is a PBX which also cooperates with a computer and has a value-added function using an application on the computer. In this case, the location where Mr. B moved is registered on the application, Mr. A inputs the ID number identifying Mr. B from the telephone, not the extension of Mr. B, and Mr. B is at that time. It is possible to call the telephone closest to the location.

In this case, there are two methods depending on where to manage members who use the network, but each has its own problems.

First, in the case of a system having a management table in which which PBX each member is currently using is registered in the database of each PBX on the network, each PB
Since there is a table in X, the same information is duplicated and each PBX is duplicated.
When the number of members to be managed above is large, there is a problem that memory resources are wasted.

When a request is made to manage a management table of which PBX each member is currently using on a computer connected to the network and to make a call from a phone under each PBX to any person, Each time the PBX makes inquiries at the same time by inquiring the computer from the PBX each time to obtain the information necessary for forming the communication path and connecting the call path based on this information, the management table is managed collectively by one computer. The load increases. Further, even if the computers are distributed, there is a problem that the communication between the computers increases and the network configuration becomes complicated.

Further, the telephone connected to the PBX is a PB
In the database of X, the physical address, which is the accommodation position of the line of each telephone, and the logical address, which is the extension number, should be managed in association with each other. Conventionally, each PBX has the extension number of the telephone under its control. I manage only. For this reason, the network user has created a telephone directory based on the network configuration diagram and is accessing the required PBX with the telephone directory. For this reason, if there is a change in the arrangement of telephones, the number of telephones, etc. due to a change in the organization or the layout in the office, the related PBX database and telephone directory must be changed for operation, which is extremely troublesome. There's a problem.

The present invention has been made in view of the above points,
It is possible to form a communication path with the other party without paying attention to the location of the other party to communicate with and the extension number of the other party, to prevent waste of memory resources, and to manage the management table for forming the communication path. An object of the present invention is to provide a communication network system capable of preventing an increase in load and communication and flexibly coping with changes in the arrangement and number of terminals such as telephones.

In the figure, as with a conventional telephone, it has a call unit 60, a display unit 61, a key control unit 63, a line unit 63, a control unit 64 for controlling the whole, a power supply unit 65, and a user information reading unit 66 and user information. It has a storage unit 67.

The user information reading section 66 corresponding to the user information input means M3 reads the user information stored in the IC memory card or the like owned by the network user,
In addition, writing is performed as necessary. This user information is stored in the user information table of the user information storage unit 67 as shown in FIG. The read user information (Mr. A) is stored in the user information table as logical information.

By the way, as the user information, for example, Mr. A's name or nickname is used. Further, since it is possible to connect a personal computer to the communication device instead of the telephone terminal, the IP address which is an identification code of a LAN (local area network) to which the personal computer is connected may be used as the user information.

As described above, the user information is input from the terminal and registered in the logical information management table only by mounting the IC memory card, so that the labor can be saved.

FIG. 7 shows a registration sequence of user information. In the figure, in step S10, a memory medium such as an IC memory card is inserted into the user information reading section 66 of the telephone.
Next, in step S12, the user information reading unit 66 reads the user information from the memory medium due to a predetermined time (timeout) after the key operation of the telephone terminal or the insertion of the memory medium. This user information is stored in the user information storage unit 6 in the telephone terminal.
7 and is stored in the user information table (step S14).

After this, a user information transfer request is issued from the control unit 64 of the telephone terminal to the communication device, and the network control unit 52 in the communication device checks the physical information of the requested telephone terminal in step S16. When the check result from the communication device is OK, the user information is read from the user information storage unit 67 of the telephone and transferred to the communication device. The network control unit 52 of the communication device registers this user information in the logical information management table of the main memory 51. Thereby, in step S18, the user information (Mr. A) is registered as the logical information corresponding to the physical information (eg, 100) of the telephone terminal, and the network control unit 52 is notified of the completion of the registration. The transfer OK is also notified to the control unit 14 of the telephone terminal, and the user registration process is completed.
