Description

Call ring control method using caller identification information in telephone terminal device

The present invention relates to a telephone terminal device, and more particularly, to a method of blocking unnecessary ringing by using caller identification information.

Today, as communication technology advances, various service functions of communication devices are required, and call forming methods of facsimile and telephones used in offices or general homes are diversified.

Such facsimile machines and telephones typically ring a ring signal sent by the switching center when an incoming call occurs to recognize a subscriber that a call has been received. In other words, the ringing ringer unconditionally irrespective of the intention of the called party subscriber, there was a problem that caused inconvenience by unnecessary reception, such as a prank call.

And, as another problem, there is a problem that the incoming ring is provided with a large noise when the call is received at midnight.

Accordingly, an object of the present invention is to provide a method for preventing unnecessary ringing generation by using caller identification information transmitted from an exchange when a call is received in a telephone terminal device.

The present invention for achieving the above object is a call ring generation limiting method using caller identification information in the telephone terminal device; The user receives and registers a specific telephone number to allow incoming ring from the user.When a call is received, the incoming caller identification information transmitted with the ring and the registered incoming ring generation allowable phone number are matched. It is characterized by allowing the occurrence of the ring.

FIG. 2 is a control flowchart for setting a call ring to be adjusted using caller identification information in a fax according to an embodiment of the present invention.

3 is a control flowchart of adjusting an incoming ring by using caller identification information in a fax according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

First, prior to explaining the present invention will be described by applying to the facsimile as an embodiment.

1 is a block diagram of a general facsimile applied to the present invention. Referring to FIG. 1, first, a central processing unit (hereinafter referred to as a central processing unit) 100 controls overall operations of a system according to a predetermined program. The memory unit 102 stores a control program for controlling the system and image data to be transmitted, and stores allowable telephone numbers for selectively ringing the ring. The OPE 104 has numeric keys and various function keys and has an LCD display for displaying the status of the system. The scanner 106 scans an original, converts an image of the original into secondary information, and applies the same to the central processing unit 100. The modem 108 modulates the input / output signal of the central processing unit 100. The network control unit (NCU) 110 forms a call path between the call line and the modem 108 under the control of the central processing unit 100. The printer 112 prints the information output from the central processing unit 100. The sensor unit 114 detects the state of the document and the recording sheet and informs the CPU 100.

As a result, the CPU 100 receives a specific telephone number to allow an incoming ring from the user in advance, registers it in the memory unit 102, and when the call is received, it is transmitted together with a ring from the exchange. Caller identification information (coller ID) and the registered allowed telephone numbers are compared and ringing occurs when the ringing outside, and if the ringing ringing does not match.

FIG. 2 is a control flowchart for setting a call ring to be adjusted using caller identification information in a fax according to an embodiment of the present invention. Referring to FIG. 2, first, in steps 200 to 210, the CPU 100 detects an input of a restricted reception mode execution key from a user, and performs a limited reception mode when there is an input of the limited reception mode execution key. To detect whether there is a request from the user to set a new incoming ring generation allowable telephone number. At this time, when there is a setting request from the user, in step 220 to 230, the user inputs a desired incoming ring generation allowable telephone number, and the central processing unit 100 transmits the telephone number to the internal memory unit 102. Register as shown in Table 1 and then end the program. However, when there is no setting request from the user in step 210, the CPU 100 reads the internal memory unit 102 to detect whether there is a registered phone number, and if there is a previously registered number, in step 230. To register again in the memory unit 102.

TABLE 1

3 is a control flowchart of adjusting an incoming ring by using caller identification information in a fax according to an embodiment of the present invention. Referring to FIG. 3, in step 300 to 310, the central processing unit 100 receives caller ID information transmitted in the idle period between the ring and the ring when the ring is received from the incoming CO line. Receive. Then, the CPU 100 detects whether the limited reception mode is set in advance by the user in step 320. In this case, when the restricted reception mode is not set, the CPU 100 performs the ring reception mode in step 330 to terminate the program. However, when the conditional access mode is set, the CPU 100 reads the telephone number pre-registered by the user in the memory unit 102 in step 340, and receives the received caller identification information (= caller's telephone number). ) To determine if they match. In this case, when the registered number and the received caller's telephone number coincide with each other, the CPU 100 outputs a ring tone to the outside in step 350 and ends the program. However, when the registered number and the received caller's telephone number do not match, the program terminates after limiting the ringing tone transmitted in step 360 without outputting to the outside.

On the other hand, in the detailed description of the present invention has been described a specific embodiment with respect to the facsimile, it can be used in general telephones and various types of telephone terminal device without departing from the scope of the present invention, those skilled in the art Since it is obvious to the present invention, a description of the specific embodiment will be omitted.

As described above, the present invention has the advantage of preventing unnecessary intrusion rings by using caller identification information transmitted from an exchange station when a call is received from a telephone terminal device, thereby increasing the competitiveness of a product. Can be.
