Abstract

본 발명은 무선전화기의 프리 다이얼링방법 및 장치에 관한 것으로, 특히 무선전화기에서 전화번호가 입력되거나 호출될때 국선점유여부를 판단하여 국선이 점유되지 않았을때는 다이얼신호를 메모리에 저장하고 LCD표시부에 디스플레이시켜 전화번호를 확인한 다음 사용자가 국선을 점유하면 메모리에 저장된 전화번호를 자동송출하며 일정시간 동안 사용자의 전화번호 입력이 없으면 프리 다이얼링 서비스를 해제하고 대기상태가 된다.The present invention relates to a pre-dialing method and apparatus for a wireless telephone. In particular, when a telephone number is entered or called in a wireless telephone, it is determined whether the trunk line is occupied. When the trunk line is not occupied, the dial signal is stored in a memory and displayed on an LCD display. After checking the phone number, if the user occupies the CO line, the phone number stored in the memory is automatically sent. If there is no user's phone number input for a certain time, the free dialing service is released and the standby state is activated.
