Abstract

본 발명은 휴대용 전화기에 관한 것으로, 페이징 기능을 채택함으로써 개방된 송수신이 아닌 원하는 상대방과의 상호호출 및 응답으로 무분별한 전파수신을 방지하고 전파사용에 대한 효율성을 증가시키도록 한 휴대용 전화기의 호출 방법 및 회로에 관한 것이다.The present invention relates to a portable telephone, and, by adopting a paging function, a method of calling a portable telephone to prevent indiscriminate radio wave reception and increase efficiency in radio wave use by mutual call and response with a desired counterpart, rather than open transmission and reception. It is about a circuit.

본 발명은 원하는 상대방에 대해서만 통화하게 되므로 무분별한 전파발사를 방지하여 전파사용상의 효율성을 증가시키고 통신상의 비밀을 확보하게 되며 무분별한 호출신호 발생으로 인한 사용자의 불쾌감을 해소할 수 있다.Since the present invention only talks to the desired counterpart, it prevents indiscriminate radio wave emission, increases the efficiency of radio wave use, secures communication secrets, and eliminates user discomfort due to indiscriminate call signal generation.

Description

휴대용 전화기의 호출방법 및 회로Calling method and circuit of portable telephone

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명인 페이저 기능이 부과된 휴대용 전화기의 개략적 구성도.1 is a schematic diagram of a portable telephone to which a pager function of the present invention is applied.

Claims (2)

통화하고자 하는 상대편 휴대용 전화기를 호출하는 경우 상대편 휴대용 전화기의 ID번호를 입력하는 제1단계, 상기 제1단계 수행후 ID번호를 코팅하고 코딩한 ID번호를 표시하는 제2단계, 상기 제2단계 수행후 ID번호를 상대편 휴대용 전화기 측으로 송출하는 제3단계, 상기 제3단계 수행후 상대방 휴대용 전화기가 ID번호를 수신하여 복조한 후 수신된 ID번호가 자신의 ID번호와 일치하는 지를 판단하는 제4단계, 상기 제4단계 수행후 수신된 ID번호가 자신의ID번호와 일치하는 경우 통화로를 개통하여 통화 가능 상태로 진입하는 제5단계 및, 상기 제4단계 수행후 수신된ID번호가 자신의 ID번호와 일치하지 않는 경우 통화로를 폐쇄하여 통화 불가능 상태로 진입하는 제6단계를 포함하는 것을 특징으로 하는 휴대용 전화기의 호출방법.When calling the other party's mobile phone to call, the first step of inputting the ID number of the other party's mobile phone, the second step of coating the ID number and displaying the coded ID number after performing the first step, performing the second step A third step of transmitting an ID number to the other party's portable telephone and a fourth step of determining whether the received ID number matches its ID number after demodulating and receiving the ID number after performing the third step. If the ID number received after performing the fourth step is identical to the ID number of the fifth step to enter into a call available state through the call path, and the ID number received after performing the fourth step is the ID And a sixth step of closing the communication path and entering a call impossible state if the number does not match. 마이크(11)로 부터 공급되는 음성신호의 편이를 제한하여 전압제어 발진기(2)측으로 입력하는 순간편이 제한 LPF(10)와, 이 순간 편이 제한 LPF(10)로 부터 공급되는 편이제한된 음성신호를 변조하여 고주파 증폭기/필터(1)를 통하여 증폭한 후 필터링하여 안테나(ANT)측으로 송출하는 전압제어발진기(2)와, 이 전압제어 발진기(2)가 일정주파수 신호를 발생하도록 조절하는 위상동기회로(4)와, 중앙처리장치(9)의 제어신호에 따라 키패드(8)로부터 입력되는 ID번호를 코딩하는 엔코더(12)와, 안테나(ANT)로 부터 수신되는 신호를 복조하여 출력하는 복조부(13)와, 이 복조부(13)로 부터 공급되는 신호를 여파 및 증폭한후 송·수신 전환 스위치(15)측으로 입력하는 앰프/필터(14)와, 앰프/필터(14)측으로부터 송.수신 전환 스위치(15)를 통해 입력되는 신호중에 포함된 ID번호를 중앙처리장치(9) 측으로 입력하는 뮤트제어부(18)와, 뮤트제어부(18)측으로부터 공급된 ID번호가 자신의 ID번호와 일치하는 경우 수신된 ID번호를 LCD(7)에 표시함과 동시 뮤트제어부(18)측으로 제어신호를 출력하여 송·수신 전환스위치(15)를 제어하는 중앙처리장치(9) 및 송·수신 전환 스위치(15)의 전환 동작에 의해 통화로가 개통되면 수신된 음성신호를 증폭하여 스피커(17)로 송출시키는 오디오앰프(16)를 구비하여 구성하는 것을 특징으로 하는 휴대용 전화기의 호출회로.Limits the deviation of the audio signal supplied from the microphone 11 and inputs it to the voltage controlled oscillator 2 side to limit the instantaneous limited LPF 10 and the instantaneous limited audio signal supplied from the limited LPF 10 at this instant. A voltage controlled oscillator 2 which modulates, amplifies through a high frequency amplifier / filter 1 and then filters and outputs the antenna to the antenna ANT side, and a phase synchronization circuit for adjusting the voltage controlled oscillator 2 to generate a constant frequency signal. (4), an encoder 12 for coding an ID number input from the keypad 8 according to the control signal of the central processing unit 9, and a demodulator for demodulating and outputting a signal received from the antenna ANT. (13) and the amplifier / filter 14 which inputs to the transmission / reception switching switch 15 side after filtering and amplifying the signal supplied from this demodulator 13, and transmitting from the amplifier / filter 14 side. ID number included in the signal input through the reception switch 15 When the mute control unit 18 inputted to the central processing unit 9 side and the ID number supplied from the mute control unit 18 correspond to their own ID numbers, the received ID number is displayed on the LCD 7 simultaneously. The voice received when the call path is opened by the switching operation of the central processing unit 9 and the transmission / reception switching switch 15 which outputs a control signal to the mute control unit 18 to control the transmission / reception switching switch 15. And an audio amplifier (16) for amplifying the signal and outputting the signal to the speaker (17). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
