Abstract

본 발명은 전화기의 통화연결을 제한하는 방법에 관한 것으로 특정지역 및 국번에 대한 통화의 연결을 선별적으로 제한하여 불필요한 전화의 사용을 억제하고 필요한 통화는 폭넓게 사용톡하여 전화기 사용에 효율성을 높인 것이다.The present invention relates to a method of restricting a call connection of a phone, by selectively restricting a connection of a call to a specific region and a station number, to suppress unnecessary use of a phone, and to increase the efficiency of using a phone by using a required call widely. .

Description

전화기의 통화 연결제한 방법How to restrict call on your phone

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 2 도는 본 발명에 따른 전화기의 개략적 구성도, 제 3 도는 본 발명에 의한 전화기의 통화 연결제한 방법을 실현하기 위한 흐름도.2 is a schematic configuration diagram of a telephone according to the present invention, and FIG. 3 is a flowchart for realizing a method for limiting call connection of a telephone according to the present invention.

Claims (1)

전화기의 통화 연결제한 방법에 있어서, 송수화수단의 오프훅에 따라 키입력수단으로부터 공급되는 키신호가 통화연결의 제한지역을 설정하기 위한 키신호인가의 여부를 판단하는 제 1 단계와, 상기 제 1 단계 수행후 통화연결의 제한지역을 설정하기 위한 키신호이면 설정 모드로 형성된후 상기 키입력수단으로부터 공급되는 제한지역 설정에 대한 지역번호 및 국번을 기억수단에 저장한 후 설정모드 종료를 위한 상기 송수화 수단의 온 훅을 감지하는 제 2 단계와, 상기 제 2 단계 수행후 상기 송수화수단의 오프 훅이 감지되면 통화로를 연결하여 발신음송출에 의해 상기 키입력수단으로부터 공급되는 상대방 전화번호에 대한 키값과 상기 기억수단에 저장된 제한지역에 대한 키값을 비교하는 제 3 단계와, 상기 제 3 단계 수행후 비교된 키값이 일치하면 국선측으로의 다이얼송출과 통화로를 차단하는 제 4 단계와, 상기 제 3 단계 수행에서 비교된 값이 불일치하면 사기 키입력수단으로부터 공급되는 키신호에 따라 DTMF 다이얼 신호를 국선측으로 송출하여 통화를 형성하는 제 5 단계 및, 상기 제 1 단계에서 상대방 전화번호에 대한 다이얼링 키신호이면 공급되는 키신호에 따라 DTMF 다이얼 신호를 국선측으로 송출하여 통화를 형성하는 제 6 단계를 포함하는 것을 특징으로 하는 전화기의 통화 연결제한 방법.A method for restricting a call in a telephone, comprising: a first step of determining whether a key signal supplied from a key input means in accordance with an off-hook of a handset means is a key signal for setting a restricted area of a call connection; If the key signal for setting the restricted area of the call connection after performing step 1 is formed in the setting mode, the area code and the station number for the restricted area setting supplied from the key input means are stored in the storage means, and the setting mode ends. A second step of detecting an on-hook of a handset means; and if an off-hook of the handset means is detected after performing the second step, a call path is connected to a counterpart phone number supplied from the key input means by a call tone transmission. Comparing the key value with respect to the key value for the restricted area stored in the storage means, and the key value compared after performing the third step is identical. If the difference between the dial transmission to the CO line and the call path is inconsistent with the fourth step, the DTMF dial signal is sent to the CO line according to the key signal supplied from the fraudulent key input unit. A fifth step of forming and a sixth step of transmitting a DTMF dial signal to the trunk line according to the supplied key signal if the dialing key signal for the other party's telephone number is formed in the first step. How to restrict call coverage. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
