Abstract

PROBLEM TO BE SOLVED: To provide sure incoming call regulation by recognizing a terminal as a call incoming enabling terminal when the password of the terminal matches at the time of an incoming call by registering the password of the terminal performing the incoming call regulation and a telephone number while using the internal control system equipment of an electronic exchange. SOLUTION: An electronic exchange 10 performs incoming call processing based on the collated result of the inputted password. Built-in control system equipment 20 has a incoming call regulation call incoming terminal registering means 21 for registering the telephone number and password of the terminal to perform the incoming call regulation. A incoming call enabling terminal registering means 22 is provided for receiving the telephone number and password of the incoming call terminal from a call originating terminal in the first call incoming to the call incoming terminal registered in the registering means 21 and for registering that terminal as the incoming call enabling terminal when the password matches. When there is call incoming from the call originating terminal, it is discriminated whether its telephone number is registered in the registering means 22 or not and when it is already registered, processing is performed by an incoming call regulation connection processing means 23 without collating the password. Therefore, when the terminal is already registered, call incoming regulation can be processed only by dialing the telephone number.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchange in which a password is registered on the receiving terminal side and only the calling terminal having the same password receives an incoming call.

Since the electronic exchange controls the storage program, it is possible to easily provide various services. Incoming call control is one of such services. Such incoming call regulation is used, for example, when a subscriber who is busy with business wants to regulate incoming calls at a certain company, and when it is desired to perform incoming call processing for incoming calls from specific subscribers.

In order to enable the incoming call from such a specific subscriber, a password is registered and the required subscriber is notified of this password. By dialing, the electronic exchange detects a match with the password registered corresponding to the telephone number, and executes the incoming call process only when the passwords match.

In the incoming call regulation of the electronic exchange using the password, there is a demand for an electronic exchange capable of surely performing the incoming call regulation by a simple procedure.

2. Description of the Related Art FIG. 23 is a block diagram for explaining a conventional example. In the figure, T1 to T9 are calling terminals, and T is a receiving terminal that regulates incoming calls. In addition, 10A is a transmitting terminal T1 to T
9 is an electronic exchange that accommodates 9, 10B is an electronic exchange that accommodates the receiving terminal T, and 20A is a maintenance console.

(A) shows an electronic exchange 10B which allows an incoming call from a specific terminal, and 210a is an incoming call acceptance terminal list, and the telephone number of the incoming terminal T (denoted by DN in the figure).
For "1234567", terminals T1 and T capable of receiving an incoming call
The telephone numbers of 9 (shown as dn in the figure) “1234560” and “1234123” are registered from the maintenance console 20A.

When an incoming call arrives at the terminal T in this state, the incoming call restriction processing section 110a confirms the telephone number of the calling terminal Ti and executes the incoming call processing if the telephone number is registered in the incoming call acceptance terminal list 210a. . In this example, the terminal T1,
Only T9 can receive a call to the terminal T, and the other terminals T2 to T
Incoming calls from 8 are restricted.

(B) is a conventional example in which the password list 220a is registered in the electronic exchange 10B. First, it is registered from the maintenance console 20A that the terminal T is a terminal that restricts incoming calls. Then, enter the password from the terminal T, and enter the password in the password list 220a (in the figure,
The password is shown as PSW and the password is "9999"
This is an example. ) Is registered.

In this state, the transmitting terminals T1 to T9 have the telephone number "12344567" and the password "99" of the receiving terminal T.
When "99" is dialed, the incoming call regulation processing unit 110a performs incoming call processing only for calls having the same password.

FIG. 24 shows a flowchart of the conventional example (A). The operation will be described below according to the steps of the flowchart (denoted by S in the figure). S1: From the terminal T that controls incoming call, the subscriber requests the maintenance person to register the incoming call restriction service (hereinafter referred to as incoming call restriction).

S2: The maintenance person registers the incoming call regulation of the terminal T from the maintenance console 20A. S3: The telephone number (abbreviated as a telephone number in the figure) of the terminal that allows the incoming call is dialed from the terminal T that regulates the incoming call, and the electronic exchange 10B registers this in the incoming-call allowed terminal list 210a.

S4: The telephone number of the terminal T is dialed from the calling terminal Ti (any one of the terminals T1 to T9 is designated as the terminal Ti). S5: It is determined whether or not the telephone number information of the terminal Ti has been received.

S6; If there is telephone number information in S5, it is determined whether or not the telephone number is registered in the incoming call acceptance terminal list 210a. S7: When the telephone number is registered in the incoming call acceptance terminal list 210a, the incoming call regulation is executed because it is not subject to the incoming call regulation.

S8: If the telephone number information of the terminal Ti is not received in S5, the electronic exchange 10B (referred to as exchange B in the flow chart) outputs the electronic number to the electronic exchange 10A (referred to as exchange A in the flow chart). Request to send information.

S9: The electronic exchange 10A is the electronic exchange 10
The telephone number information is sent to B and the process proceeds to S6. S10: In S6, the telephone number of the terminal Ti is the call-allowed terminal list 2
If it is not registered in 10a, the incoming call restriction process is executed because it is an object of incoming call restriction.

In this way, the incoming call acceptance terminal list 21
The incoming call processing is executed only for the call from the terminal registered in 0a, and the incoming call is restricted for the call from the terminal not registered. FIG. 25 shows a flowchart of the conventional example (B).

S1: From the terminal T which regulates the incoming call, the subscriber requests the maintenance person to register the incoming call regulation. S2: The maintenance person registers the incoming call regulation of the terminal T from the maintenance console 20A.

S3: The password is dialed from the terminal T which controls incoming calls, and the electronic exchange 10B registers this in the password list 220a. S4: Dial the telephone number and password of the terminal T from the calling terminal Ti.

S5: It is determined whether or not the password matches the password of the receiving terminal T. S6; If the passwords match in S5, the incoming call process is executed. S7: If the passwords do not match in S5, incoming call restriction processing is executed.

In this way, the incoming call processing is executed only when the password subsequently input to the telephone number matches the password registered in the password list 220a, and the incoming call is regulated when the passwords do not match.

In the above conventional example, the terminal T on the originating side is
Although the electronic exchange 10A accommodating i and the electronic exchange 10B accommodating the terminal T on the receiving side are different exchanges, the incoming call regulation can be executed in the same procedure even within the same exchange.

[0022]

In the above-mentioned conventional example (A), the terminal T which accepts the incoming call is registered from the terminal T on the incoming side. Therefore, if the registration from the terminal T is neglected or if the registration is forgotten, the incoming call cannot be made. If there are many terminals that accept incoming calls,
It takes a lot of time to register, update, and maintain the incoming call acceptance terminal list 210a.

In the conventional example (B), it is necessary to dial the telephone number of the receiving terminal + the password from the calling terminal, and the subscriber who frequently calls the incoming call restriction terminal adds to the telephone number each time. It is necessary to dial the password by dialing, and the dial operation is troublesome.

The present invention aims to realize an electronic exchange capable of reliably controlling incoming calls by a simple procedure.
