[0005] The pre-communication information notification service, which is generally known by the name of the number display, is a service in which the telephone number of the caller can be known before the telephone is connected. When subscribing to a subscriber line, you can choose to notify or not notify the other party of the telephone number. Even if you normally do not notify the telephone number, for example, if you have a Nippon Telegraph and Telephone Corporation (NTT) subscriber line By adding "186" before the number, it is possible to notify the other party of the source telephone number. Of course, in order to obtain the source telephone number, a device that supports it is necessary. In the case of an analog subscriber line, a modem signal, ISD
In the case of N subscriber lines, it is possible to know the telephone number from the D channel.

[0009]

FIG. 1 shows the configuration of an Internet telephone directory server system according to the present invention. The central processing unit (1) receives a command from the control program (2) in the main memory, reads a directory data file (3), and performs input / output with an input / output device (4) connected to a public line or a dedicated line. Thus, it is possible to communicate with the Internet communication device that is the call connection request source or the Internet telephone registration request source via the Internet or the public line network.

FIG. 2 shows a processing procedure from an Internet call connection request to connection. First, a call connection request (25) is transmitted from the Internet call device (20) that has requested the Internet call connection to the Internet telephone directory server system (21) through the Internet (24). The central processing unit of the Internet telephone directory server system (21) receives an instruction of a control program in the main memory and reads out an IP packet received from the input / output device. The IP packet includes a call connection request source IP address, a call connection request, a connection destination telephone number, and the like.

[0011] Next, the central processing unit reads the directory data file in accordance with a command of the control program in the main memory, specifies data corresponding to the received connection destination telephone number, and obtains the IP address of the connection destination Internet communication device. . In order to confirm that the connection destination is connected to the Internet, a connection confirmation request is instructed to the input / output device and transmitted to the previously obtained connection destination IP address (26). Upon receiving the connection confirmation request, the call destination Internet telephone device (22) transmits the authentication code transmitted at the time of registering the telephone number to the directory server system for Internet telephone (27).

Next, the central processing unit reads the authentication code transmitted from the connection destination from the input / output device according to a command of the control program in the main memory, and confirms that the authentication code matches the authentication code read from the directory file. I do. This check is necessary to ensure that the IP address of the connection destination has not been changed. If they match, the central processing unit instructs the input / output device of the connection destination to the input / output device according to the instruction of the control program in the main memory, and transmits it to the IP address of the call connection request source (28). Can be transmitted to the Internet communication device of the call connection request source. If the connection destination telephone number cannot be specified, if the authentication code does not match, or if there is no response within a predetermined time from the connection destination, this fact is notified to the connection destination IP address, for example, the connection request source IP address or generally By setting an unusable reserved IP address, it is possible to notify the connection request source.

The Internet communication device that has received the IP address of the connection destination transmits a call to the IP address, that is, transmits a connection request through the Internet (24) (2).
9) Connected Internet communication device (22)
Can be told. When receiving a connection request, the connection destination Internet communication device transmits a connection completion to the connection request source Internet communication device with the received IP address (30), and completes the connection procedure. Internet calling becomes possible.

FIG. 3 shows a procedure for registering an Internet telephone number in a directory server. First, an Internet telephone number registration request source Internet communication device (32) transmits a telephone number registration request to the Internet telephone directory server (31) through the Internet (34) together with a telephone number and an authentication code to be registered. (36). The central processing unit of the Internet telephone directory server system (21) receives an instruction of a control program in the main memory and reads out an IP packet received from the input / output device. The IP packet includes an IP address of a telephone number registration request source, a telephone number registration request, a registered telephone number, an authentication code, and the like.
The authentication code is used to specify the Internet communication device, and may be determined by a user like a password, or the serial number of the Internet communication device may be used.

Next, the central processing unit receives a command from the control program in the main memory, and if the telephone number requested for registration is not a subscriber line telephone number, reads the directory data file and stores the telephone number in the directory data file. , Add an authentication code and an IP address. If the telephone number is not a subscriber line telephone number, for example, "99
A telephone number other than the telephone number starting with "9" can be easily discriminated by arranging it as a subscriber line telephone number. If the directory data file already has the same telephone number, it will not be accepted.
Accepted as a change in P address. If there is the same IP address, it may be replaced with a new telephone number. If not replaced, a plurality of telephone numbers can be assigned to one IP address.

If the telephone number requested for registration is a subscriber line telephone number, the central processing unit receives a command of the control program in the main memory and stores the received registration request source IP address in the Internet telephone directory server. Enter the confirmation subscriber line telephone number connected to the system.
It is transmitted from the input / output device (37). At this time, it is assumed that the confirmation subscriber line has a “pre-communication information notification service” function.

Upon receiving the confirmation subscriber line telephone number, the Internet communication device of the registration request originates a call to the telephone number from the subscriber line (35) connected to its own Internet communication device (38). ). At this time, the Internet telephone directory server system transmits the call so as to provide "number notification" so that the telephone number can be confirmed.

Next, in the directory server system for the Internet telephone, the central processing unit reads out the subscriber line telephone number of the Internet communication device of the registration request source through the input / output device in accordance with a command of the control program in the main memory. At this time, the subscriber line telephone line for confirmation does not need to connect the registration request source to the actual line. Finally, the central processing unit receives the instruction of the control program in the main memory, adds the subscriber telephone number, authentication code and IP address of the registration request source to the directory data file, and completes the processing. At this time, if data having the same subscriber telephone number already exists in the directory data file, the data is deleted in advance. Also, if there is data having the same IP address, the data is deleted in advance if the authentication codes do not match. In the case of the same IP address and the same authentication code, when the same Internet communication device is permitted to assign a plurality of telephone numbers, the assignment is left as it is, and when not permitted, it is deleted in advance.

Note that the "notification of 38 subscriber line telephone number for registration" is called a predetermined number of times, and then the registration request source disconnects the line. In the Internet telephone directory server system, the central processing unit instructs the subscriber telephone number obtained in "38 Notification of subscriber line telephone number for registration" and "36 Internet telephone number registration" in accordance with a command of a control program in the main memory. If it is different from the registered telephone number obtained in "request", it is regarded as an error and the registration is not performed. However, even if different, as shown in FIG. 4, the telephone number (42) obtained by the registration request of the Internet telephone number has more digits than the telephone number (41) obtained by the notification of the subscriber line telephone number for registration. If the part completely matches the telephone number (41) obtained by the notification of the subscriber line telephone number for registration, the remaining part may be interpreted as a dial-in number and registered.

Even if the pre-communication information notification service is not available, if the Internet communication device of the registration requester is connected to the subscriber line by a modem, the registration obtained by "36 Internet telephone number registration request" It is also possible that the directory server system for the Internet telephone calls back the telephone number through the public line and communicates with the Internet communication device that has requested the registration to confirm the subscriber line telephone number.

The procedure for deleting the Internet telephone number from the directory server is as follows. First, the Internet telephone number deletion request source Internet communication device transmits the telephone number deletion request to the Internet telephone directory server via the Internet, the telephone number and the authentication code to be deleted. Sent with The central processing unit of the Internet telephone directory server system receives an instruction of the control program in the main memory and reads out the IP packet received from the input / output device. The IP packet is composed of an IP address of a telephone number deletion request source, a telephone number deletion request, a deleted telephone number, an authentication code, and the like.

Next, the central processing unit receives a command from the control program in the main memory, reads the directory data file, specifies the data in the directory data file by the telephone number requested to be deleted, and matches the authentication code. After confirming that the data exists, delete the data from the directory data file. If they do not match, an error is instructed and notified to the deletion request source to the input / output device.

[0023]

The present invention has the following effects by providing the Internet telephone directory server having the above-described configuration on the Internet.

Transmission from the Internet telephone with the same operability as the subscriber telephone can be realized. The telephone number registration only needs to register the user's own telephone, and complicated operations such as input of an IP address and the like and operations with many mistakes are unnecessary.

When the Internet communication device can use the public line simultaneously with the Internet connection means, the same telephone number as the subscriber's telephone number can be used. The burden on is small. In addition, since telephone number registration can be performed uniquely and reliably, trouble during telephone number registration can be prevented. Furthermore, it is possible to make outgoing calls without discriminating whether the destination is a subscriber telephone or an Internet telephone. That is, when calling,
The Internet telephone directory server of the present invention can be inquired through the Internet, and if it can be connected, it can be automatically transmitted as an Internet telephone, and if it cannot be connected, it can be automatically transmitted as a subscriber telephone to a public line.

In an office having only a few subscriber lines, many Internet telephone dial-in numbers can be used without incurring new costs, and the Internet telephone CTI (Computer Telephony In) can be used.
