Abstract

PURPOSE:To inform a calling side of transfer from an opposite communication terminal device that a calling-side terminal requests to another terminal device by informing the calling-side terminal device the transfer if the transfer is performed when a line is set from a center device. CONSTITUTION:When the terminal device 15 sends a request to communicate with the terminal device 13 from the transmission and reception part 21 of the terminal device 15 to the center device 11 through a transmission medium 12, the center device 11 analyzes the received request by a data analysis part 32, recognizes that the communication request as a termination side to the terminal device 13 is transferred to and registered in the terminal device 14 by referring to data registered in a transfer function registration part 33, and setting the communication path between the terminal device 15 and terminal device 14 and also sends an indication signal to the terminal device 15. The terminal device 15 recognizes the transfer of the indication signal by a data analysis part 22.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is a closed-area wired telephone device that uses vacant channels that are not used in video systems such as wired telephone systems that are used in CATV and television public listening networks. Regarding.

(Prior Art) Conventionally, this type of wired telephone system consists of one central device with a line switching function and multiple terminal devices.
The person making the call operates the terminal device and requests the center device for a line, and in response to that request, the center device sets up a communication path between the terminal devices on the calling side and the called side. , terminal devices communicate with each other over a specified line. When a certain terminal device receives a request for communication as a called party, the automatically designated terminal device can set up a communication path with the calling party's terminal device.

In this way, even in the conventional system, by registering the transfer terminal device in the center device, it was possible to transfer the communication on the called side to the designated terminal device.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional closed-area wired telephone device, even if the terminal device on the calling side is transferred using the function of the center device, the operator of the terminal device on the calling side is not notified of the transfer. The problem was that it could not be recognized.

The present invention solves these conventional problems,
It is an object of the present invention to provide a closed-area wired telephone device that can notify the calling party that the calling party has been transferred.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a transfer function registration means in the center device, a means for notifying transfer in each terminal device, and a line is set from the center device. If the calling terminal is transferred from the requested communication partner terminal to another terminal, the calling terminal is notified of the transfer.

(Function) Therefore, according to the present invention, the person operating the terminal device on the calling side can know that the call has been transferred.

(Embodiment) FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, 11 is a center device, 12 is a transmission medium composed of coaxial lines, etc., and 13 to 16 are terminal devices, and the number of terminal devices can be increased or decreased.

FIG. 2 shows the configuration of the terminal devices 13 to 16 in FIG. 1. In FIG. 2, 21 is a transmitting/receiving section, 22 is a data analysis section, 23 is a ring tone synthesis section, and 24 is a voice interface section. Further, FIG. 3 shows the configuration of the center group [11] in FIG. 1. In Figure 3, 31
32 is a transmitter/receiver section, and a data analysis section.

33 is a transfer function registration section.

Next, the operation of the above embodiment will be explained with reference to FIGS. 1 to 3. In the above embodiment, ■ terminal device 1
A function that automatically transfers a call to another specified terminal 14 when a request is received from the terminal 3 as the receiving side is registered in the transfer function registration unit 33 of the center device 11.

■ In the above state, when the terminal device 15 sends a request for communication with the terminal device 13 from the transmitting/receiving unit 21 of the terminal device 15 to the center device 11 via the transmission medium 12, the center device 11 sends and receives this request. Received from Department 31.

■ The center device 11 analyzes the received request in the data analysis unit 32, refers to the data registered in the transfer function registration unit 33, and sends a communication request to the terminal device 13 as the receiving side to the terminal device 14. Recognize that the transfer is registered.

■ The center device 11 includes the terminal device 15 and the terminal device 14.
At the same time, an instruction signal is sent to the terminal device 15.

(2) The terminal device 15 receives the instruction signal at the transmitting/receiving section 21, and recognizes at the data analysis section 22 that the instruction signal has been transferred.

■ The ring tone synthesis section 23 of the terminal device 15 synthesizes a ring tone different from the normal case in which the transfer function does not work, according to instructions from the data analysis section 22, and sends the ring tone to the person operating the terminal device 15 from the voice interface section 24. Sends out a ringing tone.

Note that in the above embodiment, the transfer has been communicated by changing the ring tone, but instead of changing the ring tone, it is also possible to communicate the transfer by voice synthesis.

Furthermore, visual display will have a greater effect.

(Effects of the Invention) As is clear from the embodiments described above, the present invention has the advantage that it is possible to notify the operator of the terminal device that the communication has been transferred with a relatively simple configuration.
