Abstract

PURPOSE:To attain reconnection to a subscriber of a new number by having only to await in the hook-off state for a prescribed time by sending a message representing an incoming call to the new number by the consecution of hook-off and transferring the incoming call to a central controller through the further consecution of off-hook. CONSTITUTION:A number revision guide device 3 informs a revised new telephone number from a voice reply circuit 31 and when an off-hook monitor circuit 32 detects off-hook further, the voice reply circuit 31 sends a message representing automatic transfer to the new number. When the subscriber A desires automatic transfer to the new number, off-hook is consecutive as it is. The off-hook monitor circuit 32 detects off-hook even after the transmission of new message and a control circuit 33 of the number revision guide device 3 requests the transfer to the new number of a call during incoming at present to the central controller 2 if a prescribed time is exceeded. Thus, the central controller 2 reconnects the telephone set TELB via a channel switch 1 upon the request.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone number change guidance system, and more particularly to a telephone number change guidance system in an exchange capable of changing the connection of a call path.

[Conventional technology]

Conventionally, in this type of telephone number change guidance system, when a call is requested to a subscriber whose telephone number has been changed and is no longer in use, the exchange connects the call to an automatic notification guidance device. The new phone number will be notified by voice.

[Problem to be solved by the invention]

The conventional phone number change guidance system described above only notifies the newly changed phone number by voice, and the calling subscriber must record the voice notification number in a memo or memorize it. However, there is a drawback that it is not possible to connect to the other subscriber unless you call the notified telephone number again.

[Means to solve the problem]

In the telephone number change guidance system of the present invention, in an exchange using a common control system that allows the connection of a set call path to be changed, the telephone number change guidance device housed in the call path switch serves as a monitoring means for monitoring off-hook of the calling telephone. , a number sending means for sending a new telephone number by voice, and a message sending means for sending a message to the effect that the call will be received at the new telephone number, and the common control device causes the number sending means to send the telephone number. If the monitoring means detects an off-hook state after the message has been sent, the message sending means sends a message, and if the monitoring means still detects an off-hook state after a certain period of time after sending this message, the telephone It is configured by reconnecting a call connected to the number change guidance device to a telephone set with a new telephone number.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and shows a case of an electronic exchange in which even after setting up a call connection path, another call connection path can be set; 1, a central control device 2, a telephone device A of subscriber A, a telephone device B of subscriber B, which are connected to the central control device 2 and the communication path switch 1;
Also shown is a number change guide device 3 connected to the call path switch 1. The number change guidance device 3 includes: - a voice response circuit 31 and an off-hook monitoring circuit 32 connected to the telephone line; and a control unit connected to the voice response circuit 31 and the off-hook monitoring circuit 32 under the control of the central controller 2; It is constituted by a circuit 33.

In the above configuration, when the old telephone number of subscriber B that has already been changed is dialed from telephone device A, central control device 2 connects telephone device A and number change guidance device 3 via call path switch 1. The 0 number change guidance device 3 notifies the voice response circuit 31 of the new telephone number by a known method, and if the off-hook monitoring circuit 32 still detects off-hook, the voice response circuit 31 again informs the new 0 number change guidance device 3 of the changed telephone number. Sends a message informing you that the number will be forwarded automatically. Therefore, if subscriber A desires automatic transfer to a new number, he continues off-hook. The off-hook monitoring circuit 32 detects off-hook even after the message is sent, and after a certain period of time, the control circuit 33 of the number change guidance device 3 requests the central control device 2 to transfer the currently incoming call to a new number. . In response to this request, the central control unit 2 causes the telephone device B to perform a connection change via the communication path switch 1.

FIG. 2 is a block diagram of another embodiment of the invention, illustrating the case in a network using common line signaling.

In the figure, three exchanges, A, B, and 0, are shown, and each exchange has the same functions as the exchange in FIG. A common line signal device 4A, 4B is connected to each of them. The number change guidance device 3B of station B also has the same configuration as the number change guidance device 3 shown in FIG.

In the above configuration, when subscriber A of station A makes a call from telephone device A and dials subscriber C, who was previously accommodated in station B, the call is connected to station B, and the central control unit 2
Since subscriber C's telephone number is not currently in use and has been changed, subscriber B connects this call to number change guidance device 3B. After this connection, the same operations as in FIG. 1 are performed until a request is made to the central control unit 2B to transfer to a new number. Having received the transfer request, the central control unit 2B requests the A station to reconnect the call to the telephone device C of the 0 station, which is the new telephone number, via the common line signaling device 4B. Therefore, the central control unit 2A of the A station restores the connection of the call to the B station and reconnects the call to the 0 station.

〔Effect of the invention〕

As explained above, the present invention monitors the off-hook status of the calling subscriber using the number change guidance device, sends a message indicating that the call will be received to the new number if the off-hook continues, and then receives the call to the central control unit if the off-hook continues. By having the call forwarded, the calling subscriber can switch to a subscriber with a new number by simply waiting off-hook for a certain period of time without having to record and dial the number communicated by voice. .
