Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to communication exchange services, and more particularly to a password-protected calling restriction service system for telephone exchange services.

[Conventional technology]

Conventionally, in this type of call restriction service system, when a call restriction service is registered at a telephone office, all calls from the subscriber's terminal are prohibited, and the service tone (
For example, the busy tone) was only sent back.

[Problem to be solved by the invention]

In the above-mentioned conventional call restriction service, once the call restriction is registered by the telephone office for the convenience of the subscriber, all calls from the subscriber's terminal are restricted until it is canceled.

An object of the present invention is to allow a specific person who knows the password to make a call even when the subscriber terminal is in the service of restricting outgoing calls due to the convenience of the subscriber, while restricting third parties. Another feature is that the cancellation of call restriction is changed from the subscriber terminal.

[Means to solve the problem]

The above object is achieved by allowing a subscriber who wishes to implement the reception restriction service to register a calling password that will enable him to make calls from his subscriber terminal during the service without going through a maintenance person at the telephone office.

[For production]

When a subscriber wishes to implement a call restriction service for reasons of convenience, the party registers a password that allows calls to be made from the subscriber's terminal. As a result, during the service, only those who know the calling password are allowed to make calls, and third parties who do not know the calling password can be restricted from making calls.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a block diagram of a switching device to which an embodiment of the call regulation service system according to the present invention is applied. In FIG. 1, 1 is a subscriber A, 2 is a subscriber B, 3 is a communication network, 4 is a talkie device, 5 is a central control device, 6 is a storage device (memory) that assists the central control device 5, 7 is a password registration table. Further, FIG. 2 is a partial schematic flowchart showing an algorithm for connection processing of the switching device in FIG. 1.

In FIG. 1, when subscriber A starts the call restriction service with password, subscriber A first dials the call restriction registration number and password.

The results are sent to the central controller 5. Central control device 5
identifies that subscriber A is registering for the outgoing call restriction service, and stores the password in the storage device (memory) 6. Next, when subscriber A who is using call restriction service makes a call to subscriber B, subscriber A dials the password and subscriber B's number.

The central control unit 5 reads this dialed number.

The central control unit 5 compares the password of the subscriber A with the password stored in the registration table 7 of the storage device (memory) 6, and if they match, allows the call from the subscriber A to the subscriber B, and the following call route network 3 A general call connection is made via the . If the passwords do not match, the central controller 5
The subscriber A is connected to the talkie device 4 via the subscriber A, and the subscriber A is notified that the call cannot be made. Therefore, calls from subscriber A under call restriction service are limited to specific persons who know the password in advance.

In addition, when subscriber A cancels the call restriction, subscriber A dials the call restriction release number, which the central controller 5 stores in the storage device (memory) 6.
Perform the process to remove the password.

From now on, subscriber A can make calls by making conventional general dialing.

That is, by providing the password registration table 7 in the storage device (memory) 6 shown in FIG. 1 and by having the central control unit 5 perform the processing shown in FIG. 2, it is possible to provide a calling restriction service from the subscriber's telephone terminal.

〔Effect of the invention〕

As explained above, according to the present invention, in the call regulation of a subscriber, the registration and cancellation of the call regulation of the subscriber can be done arbitrarily from the telephone terminal of the subscriber without going through the maintenance person of the telephone station accommodating the subscriber. Not only can you set the time, but during the call restriction service, only specific people who know the password can make calls, which prevents unauthorized calls by third parties.

Claims (1)

[Claims] 1. In the outgoing call restriction service system, which is a telephone exchange service, by registering a password that allows outgoing calls from the telephone terminal in the switching equipment that accommodates the subscriber terminal equipment, it is possible to make outgoing calls from the subscriber terminal equipment in the service. 1. A call restriction service system characterized by having a service that enables calls from a subscriber by dialing a password.
