Claims (5)

  1. 통신망에 대해서 각각 유선회선을 거쳐서 접속된 복수의 기지국과, 이들의 기지국에 대해서 무선회선을 거쳐서 접속되는 복수의 이동국을 구비하고, 이들 기지국 및 이동국에 복수의 무선주파수를 공유하게 하는 동시에 이들의 무선주파수중의 적어도 하나에 의한 전송신호의 구성을 복수의 타임슬롯을 시분할 다중화한 타임프레임으로 하고, 상기 기지국 및 이동국의 적어도 한쪽에 수신전파로 상기 무선주파수 및 상기 각 타임슬롯의 사용상황을 판정하기 위하여 사용상황판정수단과 이 사용상황판정수단의 판정결과에 따라서 이들 사용하는 무선주파수 및 타임슬롯을 결정하기 위한 무선회선결정수단과 이 무선회선결정수단에 의해서 결정된 무선주파수 및 타임슬롯에 의한 무선 회선을 기지국과 이동국과의 사이에 확립하기 위한 무선회선수단을 구비한 것을 특징으로 하는 이동무선통신시스템.
  2. 제1항에 있어서, 상기 무선회선 결정수단은 사용상황판정수단에 의해서 1타임 프레임중에 사용중의 타임슬롯이 있다고 판정된 경우에는 이 사용중의 타임슬롯의 위치를 기준으로 하여 이것으로 사용하는 타임슬롯의 위치를 결정하고 사용상황판정수단에 의해서 1타임프레임중에 사용중인 타임슬롯이 없다고 판정한 경우에는 1타임프레임주의 임의의 위치에 지금부터 사용하는 타임슬롯을 결정하는 것을 특징으로 하는 이동무선통신시스템.
  3. 제1항에 있어서, 상기 무선회선 결정수단은 사용상황판정수단에 의해서 사용중의 타임슬롯간에 복수의 공타임슬롯을 설정 가능한 기간이 있다고 판정된 경우에 이 기간중의 상기 사용중의 타임슬롯에는 접하지 않는 중간위치에 지금부터 사용하는 타임슬롯을 결정하는 것을 특징으로 하는 이동무선통신시스템.
  4. 통신망에 대해서 각각 유선회선을 거쳐서 접속된 복수의 기지국과 이들의 기지국에 대해서 무선회선을 거쳐서 접속되는 복수의 이동국을 구비하고 이들 기지국 및 이동국에 적어도 하나의 제어용무선주파수를 소유시키는 동시에 이 제어용무선주파수에 의한 전송신호를 복수의 타임슬롯을 시분할 다중화한 타임프레임에 의해서 구성하고, 상기 각 이동국은 상기 기지국에서 상기 제어용무선주파수에 의해서 보내지는 신호에 준하여 무선회선의 접속시에 기지국과의 사이에서 제어신호를 수수하기 위하여 사용하는 제어용 타임슬롯의 위치를 설정하기 위한 수단과 수단대기시에 이 수단에 의해서 설정된 각 제어용 타임슬롯중 특정기간에만 이동국을 수신상태로 하고 다른 기간은 비수신상태로 하는 배터리절약수단을 구비한 것을 특징으로 하는 이동무선통신 시스템.
  5. 제4항에 있어서, 상기 배터리절약수단은 수신대기시에 각 제어용 타임슬롯중에서 착신용으로 사용되는 타임슬롯의 수신기간내에 또 전파의 도래를 검출하는데 필요한 시간만 이동국을 수신상태로 하고 다른 기간은 비수신 상태로 하는 것을 특징으로 하는 이동무선통신시스템.
