Abstract

본 발명은 주파수 공용방식(MCA)에서 통화시 사용했던 채널에 대한 정보를 기억하고 있다가 다음 미사용채널을 탐색할때 가장최근에 사용한 채널순으로 엑세스하여 단시간에 통화로를 형성하고자한 무선전화기의 채널탐색방법 및 장치에 관한 것으로, 이러한 본 발명의 목적은 장치로는 기존의 무선전화기에 채널탐색순서 기록부를 추가 구비하고, 통화회로 구성시 설정된 기본채널이 통화중인가를 검색하여 사용채널을 선정하는 제1과정과, 상기 제1과정수행후 호출신호가 도래하면 휴대장치를 호출하여 통화시도시 통화회로를 구성하는 제2과정과, 상기 통화가 완료되면 대기모드 복귀시 마지막 통화채널을 기본채널로 설정하고 이전사용채널을 다음 순으로 순차 미루어 채널탐색 순서를 형성하는 제3과정을 순차실행 시킴으로써 달성되어 진다.The present invention stores information about a channel used for a call in a common frequency method (MCA), and then accesses the channel most recently used when searching for the next unused channel to form a communication path in a short time. The present invention relates to a channel search method and an apparatus, and an object of the present invention is to provide a channel search order recording unit to an existing wireless telephone, and to select a channel to be used by searching whether a basic channel set when configuring a call circuit is busy. A first process of performing a first call, and a second process of configuring a call-initiated call circuit when the call signal arrives after the first process is performed; and when the call is completed, the last call channel is returned to the standby mode when the call is completed. This is accomplished by sequentially executing the third process of forming the channel search sequence by setting the previous channel to the next in order.

제2도는 본 발명을 적용시킨 무선전화기의 시스템 구성도로서, (가)는 고정장치의 시스템 구성도이고, (나)는 휴대장치의시스템 구성도이다, 제3도는 본 발명 무선전화기의 채널탐색 방법을 보인 흐름도.2 is a system configuration diagram of a radiotelephone according to the present invention, (a) is a system configuration diagram of a fixed device, and (b) is a system configuration diagram of a portable device. Flowchart showing how.

Claims

The first process of setting a basic channel according to the channel search flow chart and selecting a use channel by searching whether the set basic channel is in a call circuit configuration, and calling a portable device when a call signal arrives after performing the first process. A second process of constituting a call circuit during a call and a third process of forming a channel search flow chart by setting the last call channel as a basic channel and sequentially deferring the previous use channel in the next order when the call is completed. Channel search method of a wireless telephone, characterized in that for sequentially executing.

The method of claim 1, wherein the first process comprises: reading the most recently used channel from the channel search order recorder, setting the read channel as the default channel, and if the set default channel is busy, A method for searching a channel of a wireless telephone, comprising the steps of reading a recently used channel and selecting a basic channel as a use channel if the basic channel is not in a call.

A ring signal detecting means for detecting a ring signal transmitted from a telephone station, a channel search order recording means in which information about a channel is recorded, and a signal output from the ring signal detection means is received and recorded in the channel search order recording means And a first microcomputer that searches for information on the reserved channel and forms the call circuit by occupying the best channel.
