Abstract: 핸드오프를 실현하는 이동 통신 시스템은 이동 스테이션(21), CDMA 시스템의 제 1 무선 통신 영역을 갖는 제 1 베이스 트랜시버 스테이션(11), 비-CDMA 시스템의 제 2 무선 통신 영역을 갖는 제 2 베이스 트랜시버 스테이션(31), 수신 스테이션(41), 및 베이스 스테이션 제어기(51)로 구성된다.  여기에서, 이동 스테이션은 제 1 무선 통신 영역에서 제 2 무선 통신 영역으로 이동하면서, 제 1 베이스 트랜시버 스테이션과 통신한다.  이동 스테이션이 제 1 베이스 트랜시버 스테이션으로부터 송신된 파일럿 신호의 Ec/Io 값이 제 1 임계값을 초과하게 되는 상태를 검출할 때, 베이스 스테이션 제어기는 제 2 베이스 트랜시버 스테이션에 인접하게 위치되는 수신 스테이션들을 판정한다.  그때, 베이스 스테이션 제어기는 수신 스테이션들로 하여금 이동 스테이션으로부터 송신된 업링크 트래픽 신호들을 각각 수신하도록 요청한다.  수신기 스테이션들 중에서, 베이스 스테이션 제어기는 제 2 임계값과 비교하여 최상의 Eb/No 값을 갖는 업링크 트래픽 신호를 수신하는 수신 스테이션을 선택한다.  상기 값이 제 2 임계값을 초과할 때, 베이스 스테이션 제어기는 이동 스테이션으로 하여금 제 1 베이스 트랜시버 스테이션으로부터 제 2 베이스 트랜시버 스테이션으로 하드 핸드오프를 실행하도록 요청하며, 동시에 제 2 베이스 트랜시버 스테이션으로 하여금 핸드오프를 가능하게 하도록 요청한다.  이로써, 하드 핸드오프 모드에서 비-CDMA 시스템의 서비스 영역에 대한 방향으로 CDMA 시스템의 무선 통신 영역을 확장시키는 것이 가능하다.
