JPH04351192A - Incoming call connection system - Google Patents

Abstract

PURPOSE:To attain the connection from a specific caller subscriber and the connection at a specific time with the intention of a called subscriber. CONSTITUTION:At least either allowable condition of a subscriber number of an optional registration caller subscriber A2 allowing the connection of an incoming call and connection time information is registered in advance to a restriction information storage section of a main storage device MM corresponding to the called subscriber B. At the end of registration, a registration tone is sent from a trunk RCT to the called subscriber B. At the incoming call connection processing, a central controller CP references the restriction information storage section corresponding to the called subscriber B and collates whether or not the condition is coincident with the registered allowable condition. When they are coincident, the central controller CP connects the registered caller subscriber A2 and the called subscriber B via a network NW.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call connection system for a storage program controlled exchange.

0002

2. Description of the Related Art Conventionally, in an incoming call connection in a storage program controlled exchange, if the called subscriber is free, the switching operation continues and the incoming call connection operation is performed.

0003

[Problem to be Solved by the Invention] In this conventional incoming call connection system, the calling subscriber is free to dial the number of the subscribed party if he so desires, regardless of whether the called subscriber intends to answer or not. This has the drawback that the incoming call is connected unilaterally by the exchange, and the called party is called.

SUMMARY OF THE INVENTION An object of the present invention is to provide an incoming call connection system that can regulate incoming call connections based on the terminating subscriber's intention to respond.

[0005]

[Means for Solving the Problems] The incoming call connection method of the present invention provides at least the subscriber number and date/time information of any caller that allows incoming call connection in the incoming call connection method in a storage program controlled exchange. One of the permissible conditions is registered in advance in the storage unit of the exchange corresponding to the subscriber on the called side, and when the exchange processes an incoming call, the storage unit corresponding to the called party is referred to and the registered condition is registered in advance. The sender and the called party are connected only when the permissible conditions are met.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an exchange system for explaining one embodiment of the present invention. In FIG. 1, NW is a network of storage program controlled exchanges, to which subscriber telephones are connected via subscriber circuits (not shown). A1 and A2 respectively indicate an unregistered originating subscriber who receives connection restrictions from the terminating subscriber of B and a registered originating subscriber who receives connection registration from the terminating subscriber of B, and B applies the service of incoming call restriction. Indicates the called subscriber. C.P.
MM indicates a central control unit of the storage program controlled exchange, and MM indicates a main memory controlled by the central control unit CP. The main storage device MM has a restriction information storage section that stores permission conditions for at least one of the subscriber number and date/time information of arbitrary callers that are permitted to receive incoming calls. ANT is a trunk that sends out an announcement that connection will be restricted when a call is received from unregistered calling subscriber A1 to called subscriber B who is using the service, and RCT is a registered tone that notifies that the service has been registered. It is an outgoing trunk.

The operation will be explained below. A receiving subscriber B who wishes to receive the incoming call restriction service dials a special number (1×Y) given for this service, and then dials the originating subscriber number A2 that allows incoming call connection. If there are multiple subscriber numbers of callers who are allowed to connect, dial and register all of them. Also, if you wish to connect at a specific time, you should also dial the registration number at the same time to set the time.

On the other hand, the central control device CP
When the special number (1 x Y) for this service is received from , the called subscriber B knows that he/she is requesting this service and writes the information to the main memory MM where various information about the called subscriber is stored. At the same time as inquiring information about the applicability of this service, an instruction is given to store the caller number and time setting information of the next received connection request in the main storage device MM.

Based on the instructions from the central controller CP, the main memory device MM stores the connection request caller number and time setting information in the storage area of the subscriber, if the application of this service is registered in advance. Store in the information storage unit.

[0011] The central control device CP learns that the connection request caller number and time setting information are registered in the main storage device MM by receiving the registration information from the main storage device MM, and sends the registered sound transmission trunk RCT and this service. The requested subscriber B is connected and the subscriber B is informed that the subscriber B has been registered.

[0012] When the incoming subscriber B is in such a service requesting state and an incoming call is received from the unregistered subscriber A1, the central control unit CP performs the following operations during the incoming call connection operation:
Based on the registered information in the regulation information storage section of the main memory device MM,
Learn that the connection is not allowed.

Based on this connection restriction information, the central control device CP connects the unregistered subscriber A1 to the connection restriction announcement transmission trunk ANT, and completes the operation. Therefore, unregistered subscriber A1 uses the connection restriction announcement trunk ANT.
The user hears an announcement that the connection is not possible and abandons the call.

[0014] Furthermore, when an incoming call is received from registered subscriber A2, the central control unit CP uses the caller number or time setting information stored in the regulation information storage section of the main storage device MM during the incoming call connection operation. Based on this, the incoming connection operation is performed, knowing that the connection operation may continue. As a result, the registered subscriber A2 and the called subscriber B are connected, and a conversation is started.

[0015]

Effects of the Invention As explained above, the present invention stores the subscriber number of the caller who can be connected and the connection date and time information registered in advance from the incoming subscriber in the main storage device of the exchange, and when the incoming call is connected. By comparing this information with the subscriber number of the caller and controlling the connection, connection from a specific calling subscriber and connection at a specific time can be made according to the intention of the called subscriber.

[0016] That is, it is possible to prevent connections against mistaken calls or prank calls at night, and there is no need to have a back number or a back phone for these countermeasures. Furthermore, it can be used for a wide range of purposes, such as prohibiting connections from others when waiting for a specific incoming call in an emergency, or requesting a call to only accept a specific phone number on TV or radio broadcasts. be.
