JPS6033771A - Telephone exchange with voice information service - Google Patents

Abstract

PURPOSE:To prevent a long time call by calculating a talking elapsed time of a subscriber by a telephone exchange and informing the elapsed time during talking by voice synthesis. CONSTITUTION:When a subscriber A hooks off and dials the number of a subscriber B, a channel switch between the subscribers A and B set a channel via a talking supervisory trunk IOT under the control of a central processing unti CC. When 3min time is elapsed after the start of talking, the central processing unit CC gives a command to a voice informing device BAE so as to connect a channel switch between the device BAE and the A to the caller A and inform voice. The device BAE applies voice information by the voice synthesis system that 3min time is elapsed and then opens the connection between the device BAE and the caller A.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a telephone exchange, and more particularly to a voice notification service telephone exchange for a general telephone network, which notifies the subscriber of the elapsed call time of the subscriber using voice synthesis.

In conventional telephone exchanges, if the subscriber's telephone is a coin-operated telephone, charges are charged by the exchange at fixed intervals determined by the charge index for each area (for example, 180 minutes for a local call).
When a coin storage signal is sent to the telephone every second), the telephone stores one coin. When the phone stores a coin, it detects whether the next coin has been inserted, and
If coins have not been inserted, the telephone will notify the subscriber by sounding a reminder sound for a certain period of time to prompt the subscriber to insert coins, but this does not notify the subscriber of the elapsed time of the call. With ordinary home telephones that do not accept coins, subscribers have no way of knowing the elapsed time of a call unless they measure the time on their own watch. In such cases, it would be extremely convenient if the phone user could be informed of the elapsed time from the start of the call using normal voice through the handset during a call, eliminating the waste of making long calls. This will help prevent line congestion and reduce telephone charges.

The present invention has been made to meet the above-mentioned needs, and an object of the present invention is to provide a voice notification service telephone exchange that automatically calculates the elapsed call time and notifies the user by voice.

The voice notification service telephone exchange according to the present invention has means for calculating the elapsed call time of the subscriber and means for notifying the subscriber of the call time by voice, and calculates the elapsed time from the start of the call of the subscriber and informs the subscriber of the elapsed time of the call. The elapsed time of the call is notified by voice.

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

FIG. 1 is a block diagram showing the configuration of the present invention.

In the figure, the exchange indicated by a broken line is operated by software by a central processing unit CC that performs well-known switching operations, and accommodates subscribers A and B via subscriber lines.
, a trunk ■OT'f having a well-known call monitoring function, and a voice notification device BAE that can notify the call elapsed time by voice under control from the central processing unit CC, and also accommodate the above-mentioned subscriber and device. It is composed of a well-known communication path switch SW for connecting.

FIG. 2 is a diagram showing an outline of the processing flow for calculating elapsed call time in the exchange according to the present invention. For example, when subscriber A goes off-hook on his telephone, subscriber circuitry (not shown, well-known circuitry) detects the off-hook and the central processing unit C
When C detects off-hook, the dial pulse receiver (
A well-known device (not shown) is connected to subscriber A by a communication path switch, and a dial tone is transmitted. Subscriber A, who has confirmed the caller, turns subscriber B's dial (sends a dial pulse), and the receiving device receives the dial pulse, and the central processing unit CC receives subscriber B's telephone number. is translated and the exchange accommodation location of subscriber B is extracted, subscriber B is connected to a call path switch of a ringing tone sending device (not shown, a well-known device), and a ringing tone is provided to subscriber B. is sent and waits for subscriber B's response (to take the phone off-hook). When the response from subscriber B is confirmed while waiting for a response, subscribers A and B shown in Fig.
A communication path switch is connected to subscriber A via IOT.
The call route for subscriber B is set up and the call is ready.
The exchange determines that the call has started. At the same time as the call starts, counting of the elapsed time of the call starts as shown in the processing flow shown in FIG.

When a call between subscribers A and B exceeds, for example, 3 minutes, the central processing unit C sends a notification that 3 minutes have passed as shown in Figure 2.
As shown in Fig. 1, C connects the voice notification device BAE to subscriber A, who is the caller, to the switch of the communication path between BAE and A, and also sends a voice message to the voice notification device BAE after 3 minutes have elapsed. An instruction is given to create 1 to send out using a well-known voice synthesis method. The instructed voice notification device BAg notifies the subscriber A by voice saying, ``It's been 3 minutes since the call lasted!''. When the voice notification is performed for a certain period of time, the central processing unit CC releases the communication path between BAE and A and the transmission instruction of the voice notification device BAE. Repeat the above operation every 3 minutes until the call ends, and then say, ``The call is currently 6 minutes, 9 minutes, ..., (n-3) minutes.

Subscriber A is notified of the elapsed call time with a voice message saying, "8 minutes have passed." Clear the elapsed time counter after the call ends.

As explained above, the present invention notifies the telephone user of the elapsed time of the call by voice, thereby reducing waste of time on the telephone user's time.
This has a great effect on telephone users as it can reduce the number of J conversations and also save on call charges.
