Abstract

PURPOSE:To prevent a calling subscriber desired to be treated specially from being displeased by transmitting a call signal and a busy incoming indicator tone by making them different for a terminating call from the subscriber desired to be treated specially and the terminating call from a usual subscriber. CONSTITUTION:When the terminating call arises in the subscriber (SUBA) 5, the telephone number of the subscriber originating this terminating call and the telephone number registered in a data area related to the SUBA 5 are collated with each other, and if there is no coincident telephone number, and in addition, the SUBA 5 is not busy, the usual call signal is sent by operating and restoring the relay (R) 41 of a subscriber's circuit (LC) 4. If there is no coincident telephone number,and in addition, the SUBA 5 is busy, connection between the LC 4 and a busy incoming call indicator tone trunk (IITA) 6 is executed by a channel device (NW) 3, and the usual busy incoming indicator tone is sent to the SUBA 5. When as the result of collation, the registered telephone number and the telephone number of a caller coincide with each other, and in addition, the SUBA 5 is not busy, the call signal different from the usual one is sent by operating restoring the R 41 of the LC 4. Thus, the calling subscriber desired to be treated specially can be prevented from being displeased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a subscriber identification system, and more particularly, to a system for identifying subscribers in a storage program controlled telephone exchange. The present invention relates to a subscriber identification system that sends out different ringing signals or busy call display tones depending on i.

[Conventional technology]

Conventional storage program controlled telephone exchanges do not identify the calling subscriber to the called subscriber and notify the calling subscriber before responding.

[Problem to be solved by the invention]

The above-mentioned conventional storage program controlled telephone exchange does not identify the calling subscriber and notify the calling subscriber before responding, so the calling subscriber does not notice and causes unpleasant feelings to the calling subscriber who wants to be treated separately. The problem is that it can sometimes lead to

An object of the present invention is to transmit different ringing signals and busy call display tones between incoming calls from subscribers who want to be treated separately and incoming calls from general subscribers, so that the called subscriber can The purpose of the present invention is to identify the calling subscriber before responding to the call, and to prevent the calling subscriber who wants to be treated separately from being made to feel uncomfortable.

[Means to solve the problem]

The subscriber identification system of the present invention is capable of registering and canceling telephone numbers of subscribers who want to be treated separately for the subscriber receiving the service, which is transmitted from the telephone of the subscriber receiving the service to the storage program control telephone exchange. storage means for receiving and storing signals, and when an incoming call to a subscriber receiving the service is received, the telephone number of the subscriber who originated the call is checked against the telephone number registered in the storage means; and when the verification means recognizes as a result of the verification that it is a telephone number of an unregistered calling subscriber, an instruction to send a normal ringing signal or an instruction to send a normal call-waiting incoming call display tone. control means for instructing to send out a different call signal than usual or a different call-in-call display sound than usual when the telephone number is recognized as the registered calling subscriber's telephone number; It has a subscriber circuit that receives instructions and sends a normal ringing signal or a different ringing signal to the subscriber's telephone, and a sound source for either a normal call-incoming call tone or a different call-in-call indicator tone. two trunks, and a connection means for receiving instructions from the control means and connecting a communication path between one of the two trunks having one of the sound sources and the subscriber receiving the service;
The system is configured to identify, when the incoming call arrives, whether or not the subscriber who made the call is a subscriber who the subscriber receiving the service wants to treat separately.

The normal ringing signal and the unusual ringing signal sent by the subscriber circuit may be generated by externally controlling signal intermittent means connected to one sound source.

〔Example〕

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

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG. 2 is a circuit diagram for explaining the operation of the subscriber circuit in FIG.

In FIG. 1, 1 is a central processing unit (hereinafter referred to as CC) that controls a storage program control telephone exchange; 2 is a communication path control device (hereinafter referred to as SPC) that controls a communication path device (hereinafter referred to as NW) 3; ), 4 is a subscriber circuit (hereinafter referred to as LC), and 5 is a subscriber receiving the subscriber identification service (
6 is a normal call incoming call display trunk (hereinafter referred to as IITA); 7 is a call incoming call display trunk (hereinafter referred to as IITB) that is different from the normal call incoming call display trunk 6; 8 is a push-button dial signal receiving device (hereinafter referred to as PBR), and in FIG. 2, 41 is a relay (hereinafter referred to as R) for sending out a subscriber calling signal; This is a ringing signal generator (hereinafter referred to as RG).

The parts in FIGS. 1 and 2, except for the ITB7, are known in storage program controlled exchanges.

Next, the operation will be explained.

To register or cancel the telephone number of a subscriber that the 5UBA 5 wants to treat separately, dial a predetermined special number meaning registration or cancellation and the telephone number to be registered or canceled. All dialed digits are PB
Each digit is received by R8 and read by the program stored in CC1, and the registration/cancellation of the dialed telephone number is stored in the data area regarding 5UBA5. Note that multiple registrations are possible.

Next, the operation of an incoming call to 5UBA5 will be explained.

When an incoming call occurs to 5UBA5, which receives the subscriber identification service, the telephone number of the subscriber who made the incoming call (this number can be obtained by software if the caller is accommodated in the same exchange; If the 5UBA5 is accommodated in the corresponding exchange, it is received from the corresponding exchange) and the telephone number registered in the data area related to 5UBA5 is compared.

As a result of matching, there is no matching phone number and 5UBA5
If the LC4 is not busy, a normal calling signal (for example, a 1 second on-2 second off signal) is sent out by operating and restoring R41 of the LC4. If there is no matching phone number and 5UBA5 is busy, LC4 and II

This is done within the NWB via C2, and the incoming call display tone (for example, 64 msec on-1
A repeating sound of 92 msec off - 64 msec on - 192 msec off - 64 msec on - 3520 msec off) is sent out.

〔Effect of the invention〕

As explained above, the present invention transmits different ringing signals and busy call display tones for incoming calls from subscribers who want to be treated separately and incoming calls from general subscribers. The system identifies the calling subscriber before answering the incoming call, and has the effect of preventing unpleasant feelings for the calling subscriber who wants to be treated separately.
