Abstract

본 발명은 전화기의 고정장치와 휴대장치 각각에 링(Ring)을 선택하여 울리게 함으로써 한대의 고정장치와 다수개의 휴대장치를 사용하는 멀티시스템(Multi System) 전화기에서 통화를 원하는 상대방이 있는 곳에 위치한 한대의 휴대장치 또는 고정장치에만 링신호가 울리도록 하여 외부에서 전화를 건 사람이 전화를 받을 사람을 선택하여 통화가 가능토록한 전화기의 링신호 송출 방법에 관한 것이다.According to the present invention, a ring is selected and ringed on each of a fixed device and a portable device of a phone so that one station located at a place where a counterpart wants to talk in a multi-system phone using one fixed device and a plurality of portable devices is ringed. The present invention relates to a method of transmitting a ring signal of a telephone, which allows a ringer to ring only a portable device or a fixed device of the telephone so that an external caller selects a receiver to receive a call.

종래 기술은 전화기의 고정장치와 휴대장치 각각에 링신호를 선택하여 울릴수가 없기 때문에 예로서 한대의 고정장치와 다수개의 휴대장치를 사용하는 멀티시스템 전화기에서 통화를 원하는 상대방이 있는 곳에 위치한 한대의 휴대장치 또는 고정장치에만 링신호가 울리도록 할 수가 없는 것이어서, 외부에서 전화를 건 사람이 전화를 받을 사람을 선택하여 통화할 수가 없는 사용상 불편한 문제점이 있었다.In the conventional technology, since a ring signal cannot be selected and ringed on each of a fixed device and a mobile device, for example, in a multi-system phone using a single fixed device and a plurality of mobile devices, one mobile device located at the place where the other party wants to talk is located. The ring signal does not ring only to the device or the fixed device, and there is a problem in that the caller from the outside cannot use the phone to select the person to receive the call.

이를 개선코자하여 본 발명은 전화기의 고정장치에 기능선택 스위치를 부설하고 기능선택 스위치의 온, 오프 상태를 마이크로 콘트롤 유니트(MCU)에서 인식하여 외부에서 선택적으로 전화기의 링신호(Ring Sound)가 송출되도록 하여 외부에서 전화를 건 사람이 전화를 받는 사람을 선택하여 통화할 수 있도록 한 것이다.In order to improve this, the present invention provides a function selection switch in a fixed device of the telephone, and recognizes the on / off state of the function selection switch by the micro control unit (MCU) to selectively transmit a ring sound of the telephone from the outside. It allows the caller from outside to choose who to answer the call.

Claims

The first process of detecting the on and off state of the function selection switch 4 in the MCU (13) and outputs a message if it is on, and transmits a ring signal to the fixed device (1) and the portable device (2) when the off state; And a second step of sequentially determining whether a predetermined time has elapsed after outputting the message, whether a dial is input, and whether there is a valid dial; and if the dial is valid in the second step, a ring signal to a fixed device or a plurality of portable devices corresponding to a dial value. Transmits a ring signal to the fixed device and the portable device if the value is greater than or equal to the predetermined value, and if the value is smaller than the effective dial, outputs an error message and returns to the message output step of the first step. Ring signal transmission method of the telephone, characterized in that consisting of a third process.
