Abstract

PURPOSE:To process the connection of an incoming call from a specific subscriber only without disturbing the priority processing for an emergency call by allowing a terminal telephone set to apply special dial operation to register a special subscriber number to the telephone set of which an incoming call is scheduled. CONSTITUTION:A B station 4 accommodating a special subscriber 5 is connected to an A station 2 accommodating an incoming call waiting subscriber 1 through a station side relay line 3. The specific number dialed by the subscriber 1 accommodated in a network 20 of the A station 2 is inputted to an outgoing register 21 and a subscriber number from the special subscriber 5 is received by an incoming register 22. The registers 21, 22, the incoming trunk 25, a subscriber line 26 and the network 20 are controlled by a central contoller 23. Then the telephone set 1 is subjected to special dialing so that the special subscriber number scheduled for the incoming to the telephone set 1 is registered in a storage device 24. Through the registration, only the incoming call from the special subscriber is subjected to connecting processing without preventing the priority processing of the emergency call.

Description

TECHNICAL FIELD The present invention relates to an incoming call system, and more particularly to an incoming call system in an automatic telephone exchange.

(Prior art) Conventionally, in this type of automatic telephone exchange, when there is a waiting call from a specific subscriber, especially when there are many emergency M calls from the calling subscriber that should be processed with priority, the specific subscriber number is When there was an incoming call from a subscriber, it was necessary to explain to the Phase 4 intruder that he was waiting for an emergency call and interrupt the call. Therefore, if there is an incoming call from the specified subscriber during such a call, the specified subscriber is displayed as busy, which is called busy processing, which may prevent priority processing of emergency calls. There were drawbacks.

(Object of the Invention) The object of the present invention is to provide a specific subscription in which a terminal phone performs a specific dialing operation and a call is scheduled to be received on the terminal.
It is an object of the present invention to provide an incoming call system that eliminates the above-mentioned drawbacks by registering financial resources and processes only incoming calls from a particular subscriber.

(Structure of the Invention) According to the present invention, there is a means for receiving a specific subscriber number dialed by a subscriber waiting for an incoming call, and a means for receiving a caller's number when the incoming call is received by the subscriber waiting for an incoming call. an automatic telephone exchange comprising means for comparing said particular subscriber number and said calling party number when a subscriber waiting for a call makes a call on a particular evening; , it is possible to obtain an incoming call system in which the incoming call connection process to the subscriber waiting for incoming calls is performed only when the comparison results match. The present invention will now be explained.

The figure is a block diagram showing an embodiment of the incoming call system of the present invention. In the figure, a subscriber waiting for an incoming call (hereinafter referred to as X) 1
A station 2 accommodating 8 stations 4 accommodating specific subscribers (hereinafter referred to as Y) 5 is connected via a local relay line 3. A station 2
is accommodated in the network (hereinafter referred to as NW) 20 and receives the special subscription' dialed by A general input register (hereinafter referred to as IR) 22 that receives the user number 1δr, and a central if+lJ control unit (hereinafter referred to as CC) 2 that performs predetermined sequence control within the A station 2.
3, a storage device (hereinafter referred to as MM) 24 that stores data such as the subscriber number of the Y5 from the IR22 and a control program executed by the CC23, and a station P1 accommodated in the NW2O.
Incoming trunk that interfaces with FI trunk line 3 (hereinafter referred to as 1)
cT) 25 and 7'cB station 4 is a central storage program controlled telephone exchange.

Next, the operation of this embodiment will be explained.

When Xl makes a call, the generally known calling (A connection process) is performed, and XI calls the joining center (LC) 26,
Connected to OR21 via 2O.

First, when Xl issues a registration signal, for example a push button dial signal, to register the subscription number of a specific subscriber (in this case Y5) for whom Xl is scheduled to receive a credit card, the corresponding signal is 01. < 21 via”'CCC23l
CC21, tXl recognizes that it is requesting registration of a specific subscriber number.

Next, when Xl dials the subscriber number of Y5 and then dials the information transmission completion signal (for example, the signal mentioned above), these subscriber numbers and the signals uOR21, CC2
3 is stored in the rMM 24, and registration of the subscriber number of Y5 by Xl is completed.

After that, Xl from Y5 via B station 41 inter-station relay N3
When the subscriber number arrives at A station 2, it is generally known °C
As shown, the subscriber number information is fcT25, NW2O
The signal is received by the IR22 via the IR22, and further transmitted to the CC23. When the CC 23 identifies that the call is an incoming call to the station X1 based on the information, the CC 23 causes the ICT 25 to send a calling party number transmission request signal (for example, a wink signal) to the inter-office trunk line 3. If the wink signal is damaged, the subscriber number of Y5 will not be sent back to the interoffice trunk line 3.l R22 will transmit the ICT2
5. When the subscriber code of Y5 is received via NW2O&, it is transmitted to CC23. Tell CC23. CC23
is the received calling party number and it read from MM24.
Compare the registered subscriber number recorded in I. Here, both subscriber account numbers are the same subscriber number Y5, so CC2
:H; Perform general optical 8 connection processing to tXl 4.

That is, send 8s-output 4H- to Xl via LC26, and if XI responds, XI;tLc26, Nt'
t'20 + IC'I'25.

It is possible to call Y5 via station 4, which is red throughout f'3,8.

It should be noted that the CC23 mentioned above does not indicate that the joining ministry/region number ratio is 0.0 years old and the joining fee is Y5.
5 sends a busy signal.

(Effects of the Invention) As is clear from the above explanation, according to the uninvented incoming call system, after a subscriber waiting for a tier I blur registers a specific subscriber number by dialing a percentage, Since only incoming 1d calls from
This brings about the effect that the call between the subscriber waiting for a call and the specified subscriber 26 can be made efficiently.
