- 제7항에 있어서, 상기 미디어 게이트웨이는 상기 반송파 통신망과 상기 무반송파 통신망 중 하나를 통해 제3 접속 회선을 상기 원격국에 접속시킬 수 있는 무선 통신 시스템.
- 삭제
- 제7항에 있어서, 상기 제1 및 제2 접속 회선들은 동시에 존재하여, 상기 미디어 게이트웨이가 상기 미디어 게이트웨이와 상기 이동국 사이의 통신을 상기 제1 접속 회선에서 상기 제2 접속 회선으로 핸드오버할 수 있는 무선 통신 시스템.
- 제7항에 있어서, 상기 미디어 게이트웨이는 상기 이동국이 상기 무반송파 커버리지 영역의 전이 영역에 들어갔는지 여부를 판정하는 무선 통신 시스템.
- 제11항에 있어서, 상기 전이 영역은 상기 무반송파 커버리지 영역의 외부 경계에 위치하는 무선 통신 시스템.
- 제7항에 있어서, 상기 미디어 게이트웨이는 소정의 번호로 향하는 상기 이동국으로부터의 호를 수신하는 무선 통신 시스템.
