First, the user wants to make a communication reservation.
The preset reservation information such as the usage time is registered in the reservation information table 8 of the own video conference terminal 13A by the reservation information setting means 8a.

Next, when the registration of the reservation information is completed, the own video conference terminal 13A uses the reservation information registered in the communication information control section 4 to make a call setting message from the registered reservation information in FIG. The user / user is set as described above, and a call setting message including the user / user indicating the reservation information is assembled and transmitted to the call control unit 3.

After that, the own video conference terminal 13A automatically performs a call control sequence with another video conference terminal 12 according to the communication procedure shown in FIG. That is, after the off-hook (21), the own video conference terminal 13A sends a call setting message including reservation information such as the caller number to be notified to the other video conference terminal 12, the date and time when the reservation is made, and the usage time. Send (31).

The transmitted call setup message is ISDN1.
It is received by the other video conference terminal 12 via 1. Upon receiving the call setup message, the other video conference terminal 12 transmits the call setup acceptance message (32), analyzes the call setup message, and the user / user in the call setup message communicates via the call control unit 3. It is sent to the information control unit 4. In the communication information control unit 4, the reservation information is extracted by the reservation information extracting unit 4b, and the reservation determining unit 4c searches the set value registered in the reservation information table 8 based on the extracted reservation information to make a reservation. Judge whether or not.

Next, as a result of the judgment, if the reservation information sent from the other party can be accepted, the reservation is registered in the reservation information table 8, and if the reservation information cannot be accepted, the reservation information table 8 is searched to make the reservation. Information about possible time zones is transmitted to the response information adding means 4d of the communication information control unit 4.

Then, in the response information adding means 4d,
A release message including the user / user who sets the response information such as the reservation result and the reservable time zone in the release message to be transmitted to the own video conference terminal 13A, and includes the user / user who indicates the reservation acceptance / rejection information. Is assembled and transmitted to the call control unit 3, and then ISDN
The release message is transmitted via 33 (33).
The transmitted release message is received by the own video conference terminal 13A.

The user / user in the release message thus received by the own video conference terminal 13A is sent to the communication information control unit 4 via the call control unit 3. The response information extraction means 4e extracts the response information, and when the reservation result is acceptable, the reservation result registration means 8c registers it in the reservation information table 8 and the call control unit 3 transmits a release completion message (34). The call control sequence ends, and the user is notified of the completion of the reservation through a monitor or the like.

The user can newly make a reservation setting while referring to the display screen and make a communication reservation by the same method as described above.

As described above, since the call reservation message including the reservation information and the release message including the response message are used to register the communication reservation between the communication terminal devices without performing the data communication, the self-terminal can be easily performed. It is possible to adjust and manage the communication reservation between the other terminal and the other terminal, which is very convenient.
Further, it is economically advantageous because communication reservation registration, reservation availability, confirmation of a reservable time zone, and the like are performed without connecting a line.

In the above embodiment, the video conference terminal, which is a communication terminal device, sends and receives a call setting message,
And the release message is set to be compatible with both incoming and outgoing. However, the present invention is not limited to this. For example, one communication terminal device may be configured to only support sending and receiving of a call setup message and incoming of a release message, and the other communication. The terminal device may be configured to be capable of handling only incoming call setup messages and outgoing call release messages.

In the above embodiment, the video conference terminal is described as an example of the communication terminal device, but the present invention is not limited to this, and reservation information can be added to the call setting message for transmission, and response information can be added to the release message. Any communication procedure that can be transmitted by using the above method can be applied to a communication reservation between other communication terminal devices.

In the above embodiment, the reservation information is the partner number, the date and time, and the usage time. However, the reservation information is not limited to this. It is also possible to previously set distinguishable symbols and the like and include them in the reservation information.
