Abstract

이동통신 고출력 중계장치는 종래의 이동통신 서비스의 음영지역에 고출력 소채널 이동통신 서비스가 가능하게 하여주는 시스템으로 우리나라와 같이 산악지역이 많아 서비스를 받지 못하는 지역에 무선통신서비스가 가능하게 하는데 그 목적이 있다.Mobile communication high power repeater is a system that enables high-power small-channel mobile communication service in the shaded area of the conventional mobile communication service, and enables wireless communication service in areas where there are many mountainous areas like Korea. There is this.

본 발명의 구성은 링크중계용 송수신장치(b)와 음영지역중계장치(d)로 구성되어 있다. 링크중계용 송수신장치는 제1도의 이동통신 고출력중계장치 계통도에서 보여주듯이 음영지역 이동체단말기에 기지국 n개의 채널이 할당되어 통화가 이루어지도록 기지국 n개의 채널을 음영지역 중계장치(d)에 전송시켜주고 음영지역 중계장치(d) 지시에 의해 음영지역으로 새로이 진입하는 이동체단말기가 같은 채널로 계속 통신이 가능하도록 음영지역 중계장치(d)의 주파수 조정을 마이크로컨트롤러의 지시를 받아 수행이 가능하도록 구성되어 있다.The configuration of the present invention comprises a link relay transceiver (b) and a shadow area relay (d). As shown in the mobile communication high power relay system diagram of FIG. 1, the link relay transceiver transmits n channels of the base stations to the shadow area relay device (d) so that n base stations are allocated to the shadow area mobile terminal. It is configured to perform the frequency adjustment of the shadow area relay device (d) under the direction of the microcontroller so that the mobile terminal which enters the shadow area by the indication of the shadow area relay device (d) can continue to communicate with the same channel. have.

이 과정에 의해 새로이 할당된 링크중계용 송수신장치(b)의 주파수는 전송되기전 임의의 주파수(허가받은 주파수중 기지국에서 사용되지 않는 주파수)로 변환되어 음영지역 중계장치(d)에 의해 기지국의 원래 주파수로 전환된다. 이 전환된 주파수는 이동체단말기로 송출되어 통화가 이루어지게 된다. 주파수 전환의 개념은 음영지역 중계장치(d)에서 이동체단말기로 송출되는 고출력에 의한 피드백 현상으로부터 발진을 방지하기 위한 수단으로 음영지역 중계장치의 원활한 동작을 유지하게 하여 준다.By this process, the frequency of the newly allocated link relay transceiver (b) is converted into an arbitrary frequency (a frequency not used by the base station among the licensed frequencies) before being transmitted, and the shaded area relay (d) Switch back to the original frequency. The converted frequency is sent to the mobile terminal to make a call. The concept of frequency switching keeps the smooth operation of the shaded area repeater as a means to prevent oscillation from feedback phenomenon due to the high power output from the shaded area repeater (d) to the mobile terminal.
