Abstract

본 발명은 무선 기지국과 이동통신 단말기 상호 간 채널 접속을 시도할때, 기지국과 단말기 사이에서 동일한 채널번호의 접속채널과, 상기 접속채널을 통해 할당받은 동일한 번호의 통화채널을 통해 상호 송/수신토록 하므로써, 서로간의 오버헤드 메세지를 최소화하여 빠른 채널 접속을 용이하게 한 개인휴대통신(PCS)용 디지탈 이동통신 시스템에서 무선 링크 접속 방법에 관한 것으로, 단말기와 기지국간 비동기 개인휴대통신용 디지탈 이동통신 시스템에서 상향 링크 접속을 보다빠르게 하고, 접속 시 도시 충돌을 막기 위해 단말기들의 접속 경로를 분산시킬 수 있는 채널의 종류 및 채널 할당에 대한 방법을 제시해, 위치정보수신기를 사용하지 않는 시스템 즉, 비동기 개인휴대통신용 디지탈 이동통신 시스템에서 역방향 링크 접속일때에도 파일럿 채널을 이용하여, 신속한 동기 확립을 이룰 수 있고, 계속해서 안정된 역방향 동기를 유지하며 동일한 번호의 상/하향 채널을 사용하기 때문에 더욱 빠른 채널 점유를 이룬다.According to the present invention, when attempting to access a channel between a wireless base station and a mobile communication terminal, the base station and the terminal communicate with each other through an access channel having the same channel number and a call channel having the same number assigned through the access channel. Accordingly, the present invention relates to a wireless link connection method in a digital mobile communication system for personal mobile communication (PCS), which facilitates fast channel access by minimizing each other's overhead messages, and in a digital mobile communication system for asynchronous personal mobile communication between a terminal and a base station. In order to make the uplink connection faster and prevent the city collision during connection, we suggest the type of channel and the channel allocation method to distribute the access paths of terminals, so that the system does not use the location information receiver. Pilot even in reverse link connection in digital mobile communication system Using the channel, fast synchronization establishment can be achieved, and channel retention is faster because it maintains stable backward synchronization and uses the same number of up / down channels.
