Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange, and more particularly, to an exchange for performing an incoming call (call waiting) service.

[0002]

2. Description of the Related Art In a conventional call waiting service, when another telephone B dials its own telephone while its own telephone is talking with the other telephone A, a predetermined call signal is transmitted from the exchange to the own telephone. Is done. Then, when the own phone operates the hook button according to the calling signal,
The own telephone and the other telephone B are connected, and a predetermined hold signal is transmitted from the exchange to the first telephone A. Then, when the call with the other telephone set B is completed, when the hook button is operated again with the own telephone set, the exchange controls the first telephone set to connect with the other telephone set A again.

[0003]

In this conventional exchange, in the case of a call waiting service in which both telephones are busy, a predetermined ringing signal is heard to notify that an interrupt has been received, and the predetermined ringing signal is received. The connection control is performed so that the telephone that heard the call signal can be talked to by the telephone that interrupted the operation by the telephone that heard the call signal, so that both could perform data communication and image communication with a data terminal or facsimile machine. When a call is made, nobody can hear the call signal even if there is a predetermined call signal of the call waiting service, and there is a problem that even if an important interruption is received, it cannot be recognized.

[0004]

An exchange according to the present invention accommodates a plurality of terminals having not only a telephone function but also a data communication function and / or an image communication function, and provides an interruption call receiving (call waiting) service. The first terminal is interrupted by a call to the first terminal during data communication or image communication during the telephone call;
Is registered in advance to receive the interrupt reception service, and the telephone number or PIN of the terminal that permits the interruption reception during data communication and / or image communication is registered in advance. When it is detected that the telephone number of the second terminal that has generated the call or the received personal identification number matches the telephone number or the personal identification number registered in the first terminal, the telephone number of the first terminal during a call is detected. There is provided a connection control means for forcibly disconnecting the connection and transmitting a call signal for receiving an interrupt.

[0005] An exchange according to the present invention comprises a subscriber circuit unit connected to a plurality of terminals having not only a telephone function but also a data communication function and / or an image communication function via a subscriber line, and only a telephone function from another station. A trunk circuit unit connected via a line to another station terminal having a data communication function or / and an image communication device; and the subscriber unit and the other station terminal connected to the subscriber circuit unit and the trunk circuit unit. A switch section for forming a communication path to the telephone, a receiving circuit for receiving telephone numbers, registration numbers, personal identification numbers, and the like from the terminal and the other station terminal, a dial signal, a busy signal, a call signal, a call signal for call waiting. And a signal generating unit for generating a call, etc., and a mutual telephone number of the communicating terminal, and a signal of a terminal permitting an interrupt incoming call when the terminal is communicating by data communication or / image communication. A storage unit for storing a number, a registration number, a password, a control program for controlling the entirety, and an interrupt incoming call (call waiting) service program; and a control unit for controlling the entirety by the control program and the interrupt incoming call service program. When the control unit detects occurrence of an interrupted incoming call to the first terminal during data communication or image communication of the accommodated first terminal, the control unit refers to the storage unit, and If it is detected that the telephone number, registration number, or password of the terminal that permits interruption reception during data communication or image communication is registered, the second terminal that has generated the interruption termination call is detected. A comparison is made with the telephone number or the received registration number or password, and if they match, the connection of the first terminal during the call is forcibly disconnected, and the The subscriber circuit, the switch unit, and the signal generation unit are controlled by the control program and the call waiting service program so as to transmit a chiphone call signal to the first terminal. The registration of the presence or absence of the interruption reception service and the registration of the telephone number or registration number or the password of the terminal which has the registration of the interruption reception service and permits the interruption reception call during data communication or image communication. It has a registration terminal for the storage unit.

A control unit 1 controlled by the entire exchange 1 and a control program and an interrupt reception (call waiting) service program
7 are provided.

Next, the operation during the call waiting service of this embodiment will be described with reference to FIGS.

The operation of the catch service during communication between the terminal 2-1 and the terminal 2-2 will be described below.

The subscriber A of the terminal 2-1 and the terminal 2-1
The subscriber B of the terminal 2-3 has both the subscriber C of the terminal 2-3 as an important subscriber and the telephone number of the subscriber C, the personal identification number, and the call-call service request together with the own telephone number.
6 is registered.

The control unit 17 receives a signal from the terminal 2-3, for example,
The call from the terminal 2-1 to the subscriber A is sent to the subscriber circuit unit 1.
1, via the switch unit 12 and the receiving circuit 14,
Referring to the storage unit 16, when the terminals 2-1 and 2-2 are communicating and the terminal 2-1 detects that the call waiting service request is registered (S200), the telephone is busy. If the password is present (S201) and data communication is being performed (S202), the storage unit 16 determines whether the password transmitted from the terminal 2-3 is registered for the subscriber A together with the telephone number of the subscriber C. To check (S203,
204), the telephone number and password of subscriber C are
If it matches the one registered for
Controls the switch unit 12 to forcibly disconnect the connection between the terminals 2-1 and 2-2 currently communicating. After the disconnection, the control unit 17 controls the subscriber circuit 11, the switch unit 12, and the signal generation unit 15 so that the signal generation unit 15 sends a ringing tone to the terminal 2-1.

As described above, the terminal 2-1 is connected to the terminal 2-2.
