JPH03244257A - Incoming call regulating system for electronic exchange - Google Patents

Abstract

PURPOSE:To regulate a malicious call or the forced invitation of a telephone call, etc., by providing a subscriber class in a local electronic exchange so as to receive call originating person number data, registering/canceling function and service. CONSTITUTION:Between the respective local exchanges storing a call receiving subscriber 1 and a call originating subscriber 5, when the call receiving subscriber is an incoming call regulation service receiving subscriber, a call receiving subscriber number is sent out from a transmission side exchange 4 and when a transmission subscriber number request is generated from a reception side exchange 2 receiving this subscriber number, further, the transmission subscriber number is sent out from the transmission side exchange 4. Based on the received transmission subscriber number, the reception side local exchange 2 collates the number with regulation data 3 and when the number is coincident with the registered data, the incoming call is regulated. Thus, only by registering the data of the call originating person number on the reception side, the incoming call can be arbitrarily selected.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an incoming call restriction method for an electronic exchange, and in particular, an incoming call restriction method for an electronic exchange using calling number identification [Prior Art] Conventionally, this type of incoming call restriction method has been There are incoming call route restrictions when abnormal traffic occurs in an electronic exchange, and all incoming calls to specific subscribers are restricted, but all incoming calls are allowed to arrive to general subscribers.

[Problem that the invention seeks to solve]

The conventional incoming call restriction system described above has the disadvantage that the incoming subscriber, who is a general subscriber, does not have the freedom to select connection of incoming calls based on his own request.

An object of the present invention is to provide an incoming call restriction system for an electronic exchange that allows such general subscribers to select connection of incoming calls.

[Problem that the invention seeks to solve]

The incoming call restriction method of the electronic exchange of the present invention provides calling party number restriction data, a function for registering and canceling the registration from the called party to the calling party number restriction data, and a subscriber class receiving the service. and is configured to be able to select connection of an incoming call at the request of the incoming subscriber.

〔Example〕

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

FIG. 1 is a connection diagram of an incoming call restriction system for explaining an embodiment of the present invention.

As shown in FIG. 1, a called subscriber 1 is accommodated in a local electronic exchange on the called side, and calling party number restriction data 3 is stored as one of the databases of this local electronic exchange on the called side. ing. Furthermore, the calling subscriber 1 registers and cancels the calling party number regulation data 3. On the other hand, the calling subscriber 5 is accommodated in the local electronic exchange 4 on the calling side.

If the called subscriber is a subscriber receiving the incoming call restriction service between the respective local exchanges in which the called subscriber 1 and the calling subscriber 5 are accommodated, the called subscriber number is sent from the calling side exchange 4, and this is If there is a request for the originating subscriber number from the receiving side exchange 2, the originating subscriber number is further sent from the originating side exchange 4.0 The destination side local electronic exchange 2 sends preference regulation data based on the received originating subscriber number. 3, and if it matches the registered data, an incoming call restriction operation is performed.

FIG. 2 is an operation sequence diagram for explaining the incoming call restriction operation in FIG. 1.

First, the calling subscriber registers the calling party number to be restricted in the calling party number restriction data 3 of the electronic exchange 2 shown in FIG. This registration method is performed, for example, using the function buttons of a button-type telephone in the following format.

*XY*ABCDEFGHJ #The connection operation when the originating subscriber 5 registered in the calling party number restriction data 3 calls the terminating subscriber 4 using the method described above will be explained.

As shown in FIG. 2, the calling subscriber 5 first receives the called subscriber 4.
When the number 1 is dialed, the local electronic exchange 4 receives the called subscriber number 1, activates the local electronic exchange 2, and sends out the called subscriber number 1. When the local electronic exchange 2 completes receiving the incoming subscriber number 1, it requests the local electronic exchange 4 to send the originating subscriber number 5 (ANI request). As for this ANI request method, in the case of the MFC signal method, the request is made as a backward signal, and in the case of the MF signal method, the request is made as a response signal of the line signal.

Next, when the local electronic exchange 4 receives this ANI request, it sends the originating subscriber number 5 to the local electronic exchange 2. When the local electronic exchange 2 receives the calling subscriber number 5, it checks it against the calling party number regulation data 3. As a result of this data verification, if it is registered in the calling party number regulation data 3,
Processing is performed to send a busy tone to the calling subscriber 5 without connecting the call to the called subscriber 1, and if the result of data verification is that it is not registered in the calling party number regulation data 3, the call is not processed normally. Connected to terminating subscriber 1.

Note that the above-mentioned called subscriber 1 uses the malicious call search method.

It is assumed that the originating subscriber number 5 has been specified in advance using telephone directory information, a telephone directory, or the like.

This operation sequence allows the receiving side to arbitrarily select an incoming call as long as the calling party number data has been registered.

〔Effect of the invention〕

As explained above, the present invention prevents prank calls and forcible solicitations by telephone by providing caller number restriction data, registration/cancellation functions, and subscriber classes for services in local electronic exchanges. The effect is that it can be done.

Claims (1)

[Claims] The calling party number restriction data, the function for registering and canceling the registration from the called party to the calling party number restriction data, and the subscriber class receiving the service are stored in the electronic exchange, and the incoming call is processed at the request of the called subscriber. An incoming call restriction method for an electronic exchange, characterized in that call connection can be selected.
