JPH01284151A - Automatic number informing system for busy subscriber - Google Patents

Abstract

PURPOSE:To improve service and to reduce ineffective calls by giving the notice of the telephone numbers of callers which have been terminated till then at the time of the clearing off of a callee when the caller is registered and the callee in the same exchange is busy. CONSTITUTION:A storage device 4 storing the registration of subscriber service is given. When a subscriber B is talking with a subscriber C, the subscriber B and the subscriber C are connected by a connection path 10 via a trunk in self station 6, a call 11 from the subscriber A generated is not connected since they are busy. The subscriber A on-hooks and waits for incoming. When the call between the subscriber b and the subscriber C terminates, a controller 3 learns that there has been the incoming call to the subscriber B from the subscriber A who has been subscriber service-registered from the storage content of the storage device 4, connects the subscriber B and a message trunk 5 by a connection path 12, informs the subscriber B that there has been the incoming call from the subscriber A, and informs him of the telephone number of the subscriber A by sound. Thus, the subscriber A can talk with an opposite if he waits only by dialing the number once.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic number notification system for busy subscribers.

[Conventional technology]

Conventionally, a call waiting service has been known as a service for when the called party is busy, but this is a service that is registered by the called party and is not related to the caller's intentions. be. Therefore, if the called party has not registered a call-waiting service, the possible actions to take when the called party is busy are to repeat the call as many times as possible, or to give up and put down the handset and wait for a while. I had no choice but to either call again.

[Problem to be solved by the invention]

The caller's attitude when the called party is busy as described above is a very poor service from the caller's perspective, and from the switchboard's perspective, repeating the call over and over again is invalid. There is a problem in that it increases the number of calls, which is an undesirable situation.

The object of the present invention is that if the calling party registers, if the called party in the same exchange is busy, when the called party ends the call, the phone number of the previously received caller will be displayed. Our goal is to provide a completely new subscriber service.

[Means to solve the problem]

The automatic number notification method for a busy subscriber of the present invention includes a registration means for registering whether or not a subscriber accommodated in a subscriber line exchange receives caller service, and an automatic number notification system of the subscriber line exchange. reading means for determining whether or not the called party is busy when connected within the office, and reading out whether or not the calling party receives caller service from the registration means if the called party is busy; and a reading result of the reading means. storage means for storing information until it detects on-hook of the called party if the person receives caller service, and transmits a paging signal to the called party when on-hook of the called party is detected This configuration includes notification means for notifying the caller's telephone number by voice at the time of response.

〔Example〕

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

FIG. 1 is a block diagram of one embodiment of the present invention.

A subscriber line exchange 1 accommodates subscribers A, B, and C, and includes a maintenance terminal 2 for registering subscriber services, a control device 3 for controlling the operation of the exchange, and storing registration of subscriber services. It includes a storage device 4, a message trunk 5 that notifies the caller's telephone number by voice, and an in-office trunk 6.

Here, assume that subscriber A calls subscriber B while subscriber B is talking with subscriber C. Subscriber B and subscriber C are connected by a connection path 10 via an intra-office trunk 6. A call 11 from subscriber A that occurs while the connection path 10 exists is not connected because it is busy. Subscriber A is on-hook and waiting for an incoming call.

When the call between subscriber B and subscriber C ends, the control device 3 determines from the storage contents of the storage device 4 that there is an incoming call from subscriber A who has registered the subscriber service for subscriber B. Knowing that, subscriber B and message trunk 5 are connected via connection path 12, and subscriber B is informed that there is an incoming call from subscriber A, and then subscriber A's telephone number is notified by voice. do.

FIG. 2 is a flowchart mainly showing the operation of the control device 4 described above.

When subscriber A makes a call to subscriber B and it is determined in step 21 that subscriber B is busy, the registration status of the subscriber service is checked in step 22, and if the subscriber service is not registered, the call is canceled. A middle tone is transmitted and the call is treated as lost, and if the call is heavily used, the end of the call by subscriber B is monitored in step 23. When the end of the call from subscriber B is detected, a call is made to subscriber B and the telephone number of subscriber A is notified by voice. In this way, if subscriber A is a subscriber accommodated in the same local exchange, even if the called party is busy, subscriber A can talk to the other party by dialing once and waiting. become.

〔Effect of the invention〕

As explained above, the present invention prevents the calling party from re-dialing when the called party is busy, thereby improving service for the subscriber and reducing invalid calls for the exchange. This has the effect of
