Abstract

본 발명은 무선전화기에 관한 것으로 다수개의 휴대장치를 접속하는 무선전화기에서 특정의 휴대장치가 고정장치를 통해 국선을 점유하여 사용하고 있는 상태에서 점유중인 국선을 N번 휴대장치로 전환시키고자할시 전환되는 N번 휴대장치에 국선전환 호출신호가 송출되도록 하여 국선전환인식에 효율성을 제공하도록 한 것이다.The present invention relates to a radiotelephone, and in a radiotelephone connecting a plurality of portable devices, when a specific portable device occupies and uses a CO line through a fixed device, it is desired to switch the occupied CO line to the N portable device. The CO line transfer call signal is transmitted to the N mobile device to be switched to provide efficiency in CO line transfer recognition.

본 발명은 다수개의 휴대장치를 구비한 무선전화기에서 휴대장치간의 국선전환시 호출신호 송출을 통해 국선전환 인식에 편리성을 제공하며, 국선전환 지정된 휴대장치가 아닌 다른 휴대장치로부터 보류국선점유률 요구하는 신호가 검출되면 국선점유를 요구하는 휴대장치에 에러톤을 송출하여 국선보류 전환에 신뢰성을 제공하고, 국선전환이 지정된 휴대장치로부터 소정시간동안 보류국선점유에 대한 응답신호가 검출되지 않으면 전체 휴대장치를 호출한 후 국선점유를 요구하는 휴대장치와 보류된 국선을 연결하여 통화를 수행시키는 것이다.The present invention provides convenience to recognize the CO line transfer through the call signal transmission when the CO line is switched between the portable devices in a wireless telephone having a plurality of portable devices, and requires the occupancy rate of the reserved CO line from other portable devices other than the designated CO line. When a signal is detected, it transmits an error tone to a portable device requesting possession of the trunk line and provides reliability for the switchover of the trunk line.If the response signal for the reserved trunk line is not detected for a predetermined time from the portable device designated for the trunk line switching, the entire portable unit is detected. After the call is made, the mobile device requesting possession of the CO line is connected with the reserved CO line to perform the call.

Description

무선전화기 휴대장치의 국선전환시 호출신호 송출방법Method of transmitting call signal when changing the trunk line of wireless handset

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 따른 무선전화기 휴대장치의 국선전환시 호출신호 송출방법을 실현하기 위한 흐름도.2 is a flow chart for realizing a method of transmitting a call signal at the trunk line switching of the portable telephone apparatus according to the present invention.

Claims (3)

다수개의 휴대장치를 구비한 무선전화기의 국선전환방법에 있어서, 국선을 점유하지 않은 통화대기 상태에서 소정의 휴대장치로부터 국선점유를 요구하는 신호를 감지하면 국선점유를 요구한 휴대장치의 ID번호를 분석한 후 국선점유를 요구한 휴대장치측에 응답데이타를 송신하는 제1과정과, 상기 제1과정 수행 후 국선점유응답 데이타에 따라 발신음을 확인한 후 상대방 전화번호의 입력으로 통화로를 형성하여 통화하는 상태에서 국선전환을 위한 "국선보류"신호를 검출하는 제2과정과, 상기 제2과정에서 "국선보류"신호가 검출되면 국선보류모드로 진입하여 그 상태를 표시함과 동시에 국선보류모드 진입에 대한 응답데이타를 송출한 후 국선전환을 위해 지정되는 휴대장치의 번호를 검출하는 제3과정과, 상기 제3과정에서 국선전환을 지정하는 휴대장치 번호의 ID번호를 분석한 후 해당 휴대장치에 호출신호를 송출하는 제4과정과, 상기 제4과정 수행 후 호출된 휴대장치로부터 응답신호가 검출되면 ID번호를 비교하여 지정된 휴대장치인지의 여부를 검출하는 제5과정과, 상기 제5과정 수행 후 지정된 ID번호가 일치하면 국선전환 통화로를 연결하는 제6과정을 포함하는 것을 특징으로 하는 무선전화기 휴대장치의 국선전환시 호출신호 송출방법.In the trunk line switching method of a wireless telephone having a plurality of portable devices, if a signal for requesting possession of a trunk line is detected from a predetermined portable device in a call waiting state that does not occupy the trunk line, the ID number of the portable device requesting the possession of the trunk line is determined. After analyzing the first step of transmitting the response data to the mobile device requesting the occupation of the trunk line, and after performing the first process, after confirming the dial tone according to the trunk line response response data, a call path is formed by inputting the other party's telephone number. The second process of detecting a "custody stationary hold" signal for the trunk line switching in the state; and when the "custodyhold hold" signal is detected in the second process, the station enters the trunk line holding mode and displays the state and simultaneously enters the trunk line holding mode. A third process of detecting a number of a mobile device designated for CO line switching after transmitting the response data for the CO line; Analyzing the ID number of the large device number and sending a call signal to the portable device; and if a response signal is detected from the called mobile device after performing the fourth process, the ID number is compared to determine whether or not the designated mobile device is a designated portable device. And a fifth process of detecting whether a predetermined ID number is identical after performing the fifth process, and connecting a trunk line switching call path. . 제1항에 있어서, 상기 제4과정 수행 후 설정된 소정시간동안 지정된 휴대장치로부터 응답신호가 검출되지 않으면 전체 휴대장치에 국선전환에 대한 호출신호를 송출하는 제1단계와, 상기 제1단계 수행 후 특정 휴대장치로부터 응답신호가 검출되면 응답한 휴대장치의 ID번호를 분석한 후 보류된 국선을 연결하여 통화로를 형성하는 제2단계를 포함하는 것을 특징으로 하는 무선전화기 휴대장치의 국선전환시 호출신호 송출방법.The method of claim 1, further comprising: transmitting a call signal for trunk line switching to all portable devices if a response signal is not detected from the designated mobile device for a predetermined time set after the fourth process; and after performing the first step.
