Abstract

PROBLEM TO BE SOLVED: To provide redial service to which guidance function by sound is given in the redial service function of an exchange at the time of making a telephone call. SOLUTION: A storage device 5 is provided with a memory part storing originating numbers for respective subscribers to the latent n-th number. A guidance transmission part 6 for reading telephone numbers from the memory part, converting them into sound signals and transmitting them to the calling subscriber is provided. A special number reception part 8 receives a special number (1XY) for service and connects it to the guidance transmission part 6. When the caller depresses a special key (#) by hearing sound transmitted from the guidance transmission part 6, a special key signal is received, and the telephone number stored in the memory part by the control of a central control unit 4 is selected. Then, an opposite number is automatically called from a trunk line.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a redial service function of an exchange when making a telephone call. With the computerization of exchanges, various subscriber services have come to be provided by the exchanges. For example, a speed dial service that shortens the number of frequently used parties by shortening it to 3 numbers in advance and simplifies the number of dials, or simplifies by dialing a button when continuously dialing the number of a person who has already called. In addition to redial services, subscriber services with guidance functions such as weather information and time signal services are also provided by specific numbers.

2. Description of the Related Art As a conventional redial function at the time of making a telephone call, when the terminal normally records the calling number dialed immediately before on the exchange and subsequently makes a call to the same party, for example, the # button on the numeric keypad is used. I was able to call the same number by pressing. However, with this method, you can only redial the phone number you just called,
If you wanted to call another phone number, you had to call again.

[0003]

As described above, the conventional redial function for making a telephone call is that only the most recently dialed telephone can be redialed, and the telephone number of the other party who wants to dial the most recently dialed telephone number. You may or may not be sure and may be the wrong phone call.

An object of the present invention is to provide a voice guidance function in a redial service at the time of making a telephone call so that the caller can redial by a simple button operation while confirming the other party's number with a guidance sound.

FIG. 1 shows the principle configuration of an exchange according to the present invention. In the figure, 1 is a switchboard, 2 is a calling telephone, 3 is a network, 4 is a central control unit, 5 is a storage unit, 6 is a guidance sending unit, 7 is a subscriber trunk,
8 is a special number receiving section, 9 is a special button signal receiving section, and 10 is a trunk line trunk.

The storage device 5 is provided with a memory unit for storing the calling number for each subscriber up to the latest n, and the guidance sending unit 6 reads out the telephone number from the memory unit for storing the calling number of the subscriber and outputs the voice signal. The special number receiving unit 8 is a device for converting into a special number for service (1
XY) is received and the guidance sending unit 6 is connected.

The special button signal receiving unit 9 receives the special button signal when the caller presses the special button (#) upon hearing the voice sent from the guidance sending unit 6, and by the control of the central control unit 4. Select the phone number stored in the memory,
Configured to automatically call the other party's number from the trunk line trunk 10.

A processing flowchart of the exchange of the present invention is shown in FIG. In the figure ,. A dial tone (DT) is sent to the subscriber side by the subscriber's off-hook to prepare for the telephone number input. . The subscriber side dials the special number (1XY) for the voice guidance redial service, and if the dial is received, the process automatically proceeds to the stage. Otherwise, call processing is performed. . On the exchange side, the telephone number is read out from the memory storing the transmission telephone number and notified by voice. Monitor for dialing from subscribers. . By receiving the "#" button signal from the subscriber side, the telephone number that was being played by voice at that time is set as the transmission telephone number. . Perform outgoing call processing. (Same as conventional processing)

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a voice guidance redial service of the present invention is shown in FIG. In the figure, 11 is a past dial list, 12 is an operation on the subscriber side, and 13 is a processing flowchart on the exchange side (network side).

The past dial list 11 is a list in which the past calling numbers of the calling subscriber are stored up to the past five times. The first calling number is recorded first, and the previous calling number is recorded second. Record and record up to the 5th calling number. When a new latest call origination number is recorded, the order moves in sequence, and the sixth origination number is deleted.

As for the operation 12 on the joining vehicle side, an off-hook operation, a special number (1XY) call, and a (#) button operation are performed at the time of number guidance to be connected. The calling subscriber confirms the connection by checking the voice response and operating the button and listening to the voice guidance of the number to be connected. The processing flowchart 13 on the exchange side is as follows. (1) Send a dial tone (DT) to the subscriber side off-hook on the subscriber side to prepare to receive a dial signal from the subscriber side. (2) The special number (1XY) of this service number is sent from the subscriber side, and the special number is received on the exchange side. (3) It is checked whether or not this subscriber has subscribed to the voice guidance redial service, and if not subscribed, the conventional call processing is started. (4) If the subscriber is subscribed, the past dialing number of the calling subscriber is read from the past dial list 11, (5) the list with the number i = 1 in the list order is captured, and (6) the i-th dial The number is voiced, the reception of the "#" signal from the subscriber side is monitored, and the subscriber side sequentially confirms the calling number by the voice response. (7) The subscriber presses the # button or the number to be connected when guiding the number to be connected. The exchange checks whether or not the "#" signal has been turned on. (8) If the "#" signal has not been turned on, the order is incremented by 1 and i
= I + 1. (9) It is checked whether i exceeds 5, and if i does not exceed 5, the reception monitoring of the “#” signal in (6) is repeated. (10) If i> 5, the value is returned to i = 1 again and the check is repeated. (11) When the "#" signal is turned on, if the call is made at the i-th calling number, the connection is made to the i-th calling number. i
= If it is the fourth, from the past dial list 11 03-
5434-9070 is extracted and an outgoing connection is automatically made to that number. "03-5434-9070" to subscribers
I will connect you to ". (12) Subsequent outgoing connection is based on the conventional connection process.
