본 발명은 무선전화기의 통화중 휴대장치에서 고정장치로 메세지를 보낼 때 상대방에게 들리는 데이타 노이즈를 데이타 노이즈 감소 방법에 관한 것이다.The present invention relates to a method of reducing data noise, which is heard by a counterpart when a message is transmitted from a portable device to a fixed device during a call of a wireless telephone.

종래 무선 전화기는 첨부된 도면 제1도에 나타난 바처럼 고정장치(A)에 데이타와 음성신호를 송신하는 송신부(2)와, 휴대장치(B)로부터 신호를 받는 수신부(1)와, Tel라인 쪽으로 가는 신호를 제거하는 스위치(6)로 구성되고, 휴대장치(B)에는 송신부(12) 수신부(11) 키패드(17) LCD(16)로 구성되어 있다.The conventional wireless telephone includes a transmitter 2 for transmitting data and a voice signal to the fixing device A, a receiver 1 for receiving a signal from the portable device B, and a Tel line as shown in FIG. It consists of a switch 6 which removes a signal to the side, and the portable apparatus B is comprised of the transmitter 16, the receiver 11, the keypad 17, and the LCD 16.

이와같이 구성된 종래 무선전화기의 작용 효과는 메세지 포맷도인 제3도와 고정장치의 수신 신호 처리 흐름도인 제4도를 참조하여 설명하면 다음과 같다.The operation and effect of the conventional radiotelephone configured as described above will be described with reference to FIG. 3, which is a message format diagram, and FIG. 4, which is a flowchart of receiving signal processing of a fixed device.

통화 상태가 되면 고정 장치(A)의 Cpu는 Tel라인쪽 스위치(6)을 온 한다. 이 상태에서 휴대장치(B)가 고정장치(A)쪽으로 메세지를 보내면 고정장치(A)에서는 메세지 전체를 확인한 후 처리해 준다.When the call state is established, the Cpu of the fixing device A turns on the switch 6 on the Tel line side. In this state, when the portable device B sends a message to the fixed device A, the fixed device A checks the entire message and processes it.

이 메세지는 스위치가 온이기 때문에 상대방에게 들리게 된다.This message is heard by the other party because the switch is on.

그러나 이와같은 종래 무선 전화기는 통화중 고정장치는 전체 메세지를 받은 후 처리하기 때문에 메세지 전체가 라인쪽으로 나가게 되어 상대방에게 노이즈로 작용하게 되는 문제점이 있었다.However, such a conventional wireless telephone has a problem in that the fixed device during a call processes the entire message after receiving the entire message and thus acts as a noise to the other party.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 통화 상태에서 메세지를 수신할 때 메시지(ID)의 조합으로 이루어진 기신호를 받으면 고정장치(A)의 스위치를 소정시간 끊고 계속해서 전체 메세지를 수신하여 처리하는 데이타 노이즈 감소 방법을 창안한 것으로 이하 본 발명을 첨부된 도면에 의거 상세히 설명하면 다음과 같다.In order to solve the conventional problem, the present invention, when receiving a message in a call state when receiving a pre-signal consisting of a combination of messages (ID), switch off the fixed device (A) for a predetermined time and continue to receive the entire message processing The present invention will be described in detail with reference to the accompanying drawings.

본 발명 무선전화기의 구성은 종래의 것과 동일하게, 고정장치(A)에 데이타와 음성신호를 송신하는 송신부(2)와, 휴대장치(B)로 부터 신호를 받는 수신부와 Lel라인 쪽으로 가는 신호를 제어하는 스위치(6)로 구성되고, 휴대장치(13)에는 송신부(12) 수신부(11), 키패드(17) LCD(16)로 구성한다.The configuration of the radiotelephone according to the present invention is the same as that of the prior art, and includes a transmitter 2 for transmitting data and a voice signal to the fixed device A, a receiver for receiving a signal from the portable device B, and a signal directed toward the Lel line. It consists of the switch 6 which controls, and the portable apparatus 13 consists of the transmitter part 12, the receiver part 11, the keypad 17, and the LCD 16. As shown in FIG.

이와같이 구성된 본 발명의 작용 효과를 고정장치의 수신 신호 처리 흐름도인 제5도를 참조하여 상세히 설명하면 다음과 같다.The operation and effect of the present invention configured as described above will be described in detail with reference to FIG.

통화중에 휴대장치 CB로부터 메세지가 오면 먼저 수신되는 동기신호를 비교하여 같으면 Lel라인쪽의 스위치(6)를 메세지가 들어오는 시간(T1)만큼 끊어 상대방에게 이후에 들어오는 메세지(ID1, ID2, ID3) 카맨드 체크씽에 의한 노이즈가 들리지 않게 한다.If a message comes from the mobile device CB during a call, compare the received synchronous signal first, and if it is the same, switch the switch 6 on the Lel line side by the time T1 for the message to be received and then send the message (ID1, ID2, ID3) to the other party. Makes it impossible to hear noise caused by mandatory checking.

그리고 소정시간(T1) 이후에는 다시 스위치(6)를 온하여 준다. 만약 처음 동기신호를 수신하여 스위치를 오프한 후 이어서 들어오는 메세지를 수신하지 못하여도 소정시간(T1)이후 스위치(6)를 다시 온하여 주어야 한다.After the predetermined time T1, the switch 6 is turned on again. If the first synchronization signal is received and then the switch is turned off, the switch 6 should be turned on again after a predetermined time T1 even if a subsequent incoming message is not received.

(MCA)무선 전화기에는 고정장치 (A)와 휴대장치 (B)의 혼신을 방지하기 위해 메세지를 주고 받을 때 항상 해당장치의 고유번호 (ID: Lo bit 이상)를 포함하도록 되어 있다.(MCA) Wireless telephones must always include a unique number (ID: Lo bit or higher) of the device when sending or receiving messages to prevent interference between the fixed device (A) and the portable device (B).

그러므로 동기신호를 메세지의 조합으로 만들어 메세지화하여 다른 시스템에 의해 일정시간(ID) 동안 스위치(6)를 오프시키는 것을 방지한다.Therefore, the synchronization signal is made into a combination of messages and messaged to prevent the switch 6 from being turned off for a certain time ID by another system.

이상에서 상세히 설명한 바와 같이 본 발명은 휴대장치에서 메세지를 보내면 동기신호를 비교해서 같으면 고정장치의 스위치를 먼저 오프하기 때문에 상대방에게 들리는 스위치에 의한 노이즈를 상당히 줄일 수 있는 효과가 있다.As described in detail above, the present invention has the effect of significantly reducing the noise caused by the switch being heard by the other party because the mobile device transmits a message and compares the synchronization signal, and if it is the same, the switch of the fixed device is first turned off.
