Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call answering and answering system processed by an electronic exchange, and more particularly, to an electronic exchange having one called party number.
Connect incoming calls from multiple callers to a call in the order in which they arrive
On incoming order response connection method that.

[0002]

2. Description of the Related Art In a conventional incoming call order answering and connecting system, the order of incoming calls is stored in an electronic exchange, a caller is kept waiting in that state, and when the called party becomes available for reception. In this method, incoming calls are connected in order.

[0003]

In the above-described conventional incoming call sequential answering connection method, the calling party must wait in the same state until the called party can accept the call, and the number of incoming calls is large. In some cases, the caller spends a considerable amount of time until the connection is established, and depending on the waiting time, the caller cannot wait for the call and abandons the connection. In addition, there is a drawback in that, depending on the number of incoming calls or the number of receptionists, it is necessary to consider increasing the number of lines and increasing the number of receptionists in order to reduce the waiting time.

[0004]

According to the present invention, there is provided an incoming call answering and answering connection system which utilizes a stored program and data to control an exchange of a line accommodated in a central processing unit when an incoming call is received. and receiving and identifying means receiving and identifying the calling party number followed the called party number, the predetermined et to the calling party
Is and announcement device for delivering messages, once a post connecting the announcement equipment to the calling line the message transmitting the calling line upon receiving and distinguishing the calling party number
A first connecting means for recovering the electronic exchange with the calling party number to separately provided computer to said calling party number
Sending means for sending the associated called party number, and the calling line once restored based on a call back connection instruction
And a second connection means for making a call back connection to the computer, wherein the called party of the called party number is
The call return connection instruction is issued to the electronic exchange in the order in which the information of the calling party number and the information of the called party number received from the electronic exchange when the mobile telephone is ready to respond to the incoming call of the call number. and have a connection instruction means, the called party number
Incoming calls from multiple callers for a call are restored after being restored
Call back and connect in order.

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

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a diagram showing a state transition in the case of a local line connection in this embodiment.

In FIG. 1, the present embodiment comprises an electronic exchange and a computer, and the electronic exchange has an incoming trunk circuit (hereinafter referred to as ICT) 5 for interfacing an incoming call from a central office.
An outgoing trunk circuit (hereinafter referred to as OGT) 12 for interfacing to outgoing calls to the office line, and a subscriber telephone (hereinafter referred to as STA).
And a line circuit (hereinafter referred to as L
C) 6 and a register (hereinafter referred to as REG) 8 for receiving and identifying the STA 7 and the calling party number and called party number from the office line.
An announcement device (hereinafter referred to as ANT) 9 for announcing information stored in advance to the caller, ICT5, OGT1
2, a switch (hereinafter referred to as SW) 1 for interconnecting LC6, REG8 and ANT9, and a central processing unit (hereinafter referred to as CPU) 2 for controlling the entire electronic exchange by making full use of stored programs and data; The computer has a database (hereinafter referred to as D) storing caller number / callee number information.
B) 4, a HOST dedicated terminal (hereinafter referred to as TERM) 11 for inputting reception acceptability, DB4 and TERM11
To connect the CPU 2 to the CPU-HOST bus (hereinafter referred to as CH bus) 10 and to return the information of the calling party number and the called party number received from the CPU 2 via the CH bus 10 to the CPU 2 in the order in which they were received. And a host computer (hereinafter referred to as a HOST) 3 having a function of giving an instruction.

Next, the operation of this embodiment will be described with reference to FIGS.

When the incoming call from the office line is detected by the ICT 5, the CPU 2 controls the SW1 to receive the dial signal from the office line and connects the ICT 5 to the REG 8 (state 2). Thereafter, when receiving the called party number and the calling party number coming from the ICT 5, the CPU 2 connects the ICT 5 to the ANT 9 and sets the received called party number and the calling party number to H.
It is sent to the OST 3 via the CH bus 10 (state 3). As a result, the caller goes on-hook in accordance with the instruction from the ANT 9 saying "Please wait after dropping the telephone". (State 4).

The HCST 3 sequentially stores the received called party number and the called party number information in the DB 4 (state 4).

[0011] Then, the input which enables the called party to accept is H
When the call is made from the TERM 11 connected to the OST 3 (state 5), the HOST 3 reads out the information stored first in the called party number and the called party number information stored in the DB 4 and sets the called party number to the calling party. The number and the calling number are converted into the called number, respectively, and an outgoing connection instruction is issued to the CPU 2 via the CH bus 10. As a result, the CPU 2 automatically performs the outgoing connection process and enters the talking state (state 6).

In this embodiment, a dedicated terminal TE of HOST3 is used.
Although the description has been given by inputting the state of the reception board from the RM 11, a means for notifying the HOST 3 of a change in the state of the STA 7 can be provided, so that automatic processing can be easily analogized.

[0013]

As described above, according to the present invention, an electronic exchange for controlling a switching connection of a line accommodated in a central processing unit by making full use of stored programs and data is provided with a called party number when an incoming connection is established. Receiving / identifying means for receiving / identifying the caller number, and sending a predetermined message to the caller.
Connect the announcement device to be sent and the announcement device to the calling line when the caller number is received and identified, and send the message
First connection means for temporarily restoring the calling line after transmission, and caller ID and calling to a computer provided separately from the electronic exchange
Transmission means for transmitting the called party number associated with the called party number, and the calling line once recovered based on the call back connection instruction.
And a second connecting means for connecting a call-back against the computer, the calling party the called party of the called party number received from the electronic exchange when it becomes responsive state to an incoming call calling party number in the order of receiving the information of the number and called party number have a connection instruction means for a call-back connection instruction to the electronic exchange
The incoming call from multiple callers to the called party number
By responding to the incoming call after the recovery and connecting back
Even if the number of incoming calls for one called party number is large and the traffic is high, there is no need to keep the calling party waiting, and it is only necessary to prepare a line slightly larger than the number of acceptors, and the line effect is also improved. It has the effect of being able to increase. In addition, since the return call is basically used for all incoming calls, the call charge is also borne by the called party, so that there is an effect that the improvement of the service can be appealed.
