Abstract

PURPOSE: A method for rejecting incoming of a telephone call is provided to efficiently interrupt a vicious call without passing through a vicious call interrupting device of an exchange system of a telephone office. CONSTITUTION: An incoming signal is input through an RF receiver(S1). A receiver compares the incoming telephone number with information of a list of incoming rejected telephone numbers(S2). If the incoming telephone number coincides with one of the incoming rejected telephone numbers, the incoming reject information processor controls a signal processor for interrupting a telephone bell(S3). The incoming reject information processor instantaneously disconnects a call connected from the incoming rejected telephone number(S4). An incoming reject message is displayed on a screen of a display window(S5). If the incoming telephone number coincides with none of the incoming rejected telephone numbers, the incoming reject information processor connects the call to form a telephone conversation(S6,S7).

Description

How to reject a call {Refusal system of telephone signal and message}

The present invention relates to a method for blocking an incoming call signal for a phone number set in advance in a phone such as a mobile phone, and rejects an incoming call signal from an obscene call, a prank call, or a violent call, and immediately makes a call. It relates to a technique for providing a method of blocking.

In particular, the present invention provides a method for effectively blocking malicious calls in a user's phone itself without passing through a malicious code blocking device of an exchange terminal configured in a telephone station.

When a malicious caller continues to suffer from mischief calls, threatening calls, etc., regardless of time, conventionally, a method of applying for rejection of a malicious call to the telephone station is blocked so that the malicious call can be blocked through a terminal device in the telephone company. It was.

Korean Patent Publication No. 2000-28408 discloses an example of a conventional malicious call blocking function.

In the conventional malicious call blocking function, when the call rejection information that is not desired to be called is stored in the call reject list area of the home location register (HLR) by a specific subscriber, the call is received when the call is rejected to the applicant. If the call originates from a rejection number already registered on the reject list, the call exchange service is blocked by the telephone company's switching system so that a malicious call blocking service is performed.

That is, a process of transmitting, to the HLR, an incoming information request signal including a called number dialed from a third party (caller) and information of the third party, and a telephone subscriber corresponding to the called number registered in the call rejection service of the HLR. If the HRL compares the third party's information with the rejection information, and if there is a rejection information that matches the third party's information, the HRL blocks the call forwarding request from the third party. The service goes through the process.

The control method for the conventional malicious call rejection function configured as described above will be described with reference to the control flowchart of FIG. 2.

If a call is received from a third party for a subscriber who has applied for rejection while the rejection request information is stored in the rejection list area of the HLR, the exchange system of the telephone company where the third party is located recognizes it and After comparing the dialed called number with the information of the third party (S21), the incoming request information signal necessary for call processing is transmitted to the HLR (S22).

Subsequently, the HLR checks whether the number of the subscriber (receiver) corresponding to the called number is registered in the rejection service using the called number included in the incoming request signal transmitted from the third party's exchange system (S23).

When the subscriber is registered in the rejection service, the HLR checks whether information matching with the information of the third party included in the incoming request signal is registered in the rejection service (S24), and the corresponding incoming request signal is If there is a switch request to switch the incoming request signal is checked (S25).

On the other hand, when the subscriber is not registered in the rejection service in step S23, or when there is no rejection service information that matches the information of the third party in step S24, a call can be made between the third party and the subscriber. Call processing so that (S30).

In addition, when the switching request of the incoming request signal is set in step S25, the HLR checks whether the switching request of the incoming request signal is a switching request for the voice service system (S26), and when the switching request of the voice service system is performed. The call is set to be forwarded to the voice service system (S27).

When the call is set up in the voice service system, the voice message transmitted from the third party to the subscriber is provided (S28), and then the call is released (S29).

On the other hand, when the request for switching the incoming request signal from the subscriber is not set in step S25, the HLR transmits a call rejection signal including the reason for the rejection to the third party's telephone exchange system, to the third party. (S31).

As described above, the method of rejecting a call from a third party (sender) to a subscriber (recipient), that is, a method of rejecting a call to a specific telephone number, must go through the HLR provided by the telephone company and the exchange system, and reject the call to the HLR of the telephone company. There is a disadvantage that you must apply for the service separately.

The present invention has been made in view of the above problems, and when the subscriber (recipient) enters the incoming call rejection number into the memory of the subscriber's own phone, the subscriber receives the rejected call number from the third party. Automatically terminate a call without alarming.

That is, according to the present invention, when a call number for rejecting an incoming call is stored in a call reject information processing politics of a telephone such as a mobile phone of a receiver, the call reject information processing device is connected to a signal processing unit when a call to the call number for rejecting the incoming call is connected. Control to avoid ringing tones or alarms, and immediately disconnect the call. Of course, the receiver should be configured to receive information from the unsubscribed telephone number automatically or through a key input on the display window of the receiver's telephone.

Accordingly, it is an object of the present invention to provide a malicious code blocking method capable of blocking the connection of malicious codes in the telephone itself, such as a cellular phone, without going through an exchange of a telephone station.

The present invention, while processing the RF transmission and reception signal by the voice processing unit and the signal processing unit to the incoming and outgoing sound and the call sound in order to achieve the above object, includes a call reject information processing politics for controlling to display the information selectively on the display window through the key input unit In a call rejection method of the telephone to say,

Inputting a call reject telephone number into the call reject information processing politics;

The incoming rejection information processing politics, receiving a signal input from the RF receiver from a signal processor to determine whether a call signal coincides with a call signal for the incoming call rejection number;

If there is a call signal corresponding to the call signal for the incoming call rejection number, the incoming call rejection information processing politics controls the signal processing unit so as not to receive a ringing tone and to disconnect the call without disconnecting the call;

Allowing information of a call connected from the incoming call rejection to be automatically stored in a memory unit of the incoming call rejection information processing politics;

And selectively displaying the stored information on a display window through an automatic or key input unit.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to FIGS. 1 to 3.

In general, the configuration of a telephone apparatus such as a mobile phone is, as shown in FIG. 1, a rejection information processing politics 1, an audio processing unit 2, a signal processing unit 3, a display window 4, a key input unit 5, and an RF transmitter. (6), the RF receiver 7, the receiver 8, and the transmitter 9.

The rejection information processing politics 1 includes a real time clock and a controller of the display window 4, and is used for storing an operating system, a ROM used for storing basic programs and font image data, and storing a downloaded program or database. A flash ROM, a program load for executing a program stored in the flash ROM, a system memory area used by the operating system, and a RAM for allocating dynamic memory required during program execution.

The key input unit 5 includes keys for setting various functions and modes and numeric keys for performing a dialing function. Further, the key data input through the key input unit can be displayed on the display window 4 through the reception rejection information processing politics or the key data can be transmitted through the signal processing unit 3 and the RF transmitter 6.

On the other hand, the RF transmitter 6 outputs the transmitted voice signal output from the voice processor 2 through the transmitter 9 or the key input data signal input through the key input unit through the antenna 10. The RF receiver 7 demodulates the signal received through the antenna 10 and outputs it to the voice processing unit 2, and simultaneously outputs the control data to the incoming rejection information processing statistic to display the display window 4 or the receiver 8 To print information.

The signal processor 3 controls the RF transmitter / receiver to convert the control data output from the incoming call rejection information processing politics of the cellular phone into a transmission / reception frequency.

The voice processor 2 amplifies the voice signal input from the transmitter or the voice signal received from the RF receiver 7.

A call rejection method of a telephone blocking a malicious call using the telephone configured as described above will be described in detail with reference to the control flowchart of FIG. 3.

First, when an incoming signal is input from the third party through the RF receiver 7 (S1), the information of the incoming call number list that the receiver has previously set and input into the memory of the incoming rejection information processing politics 1 of the telephone. Judge with comparison. The comparison between the incoming signal and the incoming call rejection number is made by the action of the signal processor 3 and the incoming call rejection information processing politics 1 (S2).

If there is a telephone number corresponding to the incoming signal among the incoming call reject numbers, the incoming call rejection information processing politics 1 controls the signal processing unit 3 to block the telephone ringing (S3), and the receiver receives the incoming call from the incoming call number. The rejection information processing politics 1 controls the fact that the call is received only through the display window of the phone.

When the ringing tone is blocked due to the action of the signal processing unit 3 and the rejection information processing politics 1, the incoming call rejection information processing apparatus 1 instantly disconnects the incoming call from the incoming call rejection phone number ( S4).

As described above, the reason for disconnecting the call without disconnecting the call momentarily is because the malicious call connector keeps the ringing tone for a long time and blocks the connection of other normal calls if only the ring tone is blocked. It can effectively block malicious connections.

When a malicious call, i.e., a call connected to a call rejection phone number is disconnected, the call reject message is displayed on the screen of the display window 4 at the same time (S5) or stored in the memory section of the call reject information processing politics. The rejection message stored in the memory of the rejection information processing politics can be displayed on the screen of the display window by the receiver operating the key input unit 5 as necessary.

On the other hand, if there is no same information in the step (S2) comparing the information of the incoming call rejection list and the incoming call signal, it is determined that it is not a bad call to connect the call by the existing method (S6) and to make a call (S7) do.

The present invention comprises the steps of inputting a call rejection telephone number into the call reject information processing politics 1 of the telephone as described above, and the call reject information processing politics signal the signal input from the RF receiver 7 Determining whether there is call signal information corresponding to the call signal for the incoming call number received from the processing unit 3, and if there is call signal information corresponding to the call signal for the call reject number The stationary process controls the signal processing unit so that an incoming sound (alarm) does not ring and at the same time stops a call signal, thereby effectively blocking malicious calls from the telephone itself without going through the telephone exchange system. Can be obtained.
