Abstract

전체 채널 세트의 특정 서브세트에 할당되는 각각의 시스템셀을 갖는 서브세트로 구분되는 전체 채널 세트에 다이나믹한 액세스를 용이하게 하는 통신 시스템 및 순서있는 차용 방법에 관한 것이다. 물리적인 레이아웃에 의해 부과된 다양한 구속조건을 침해하지 않는 방식으로 채널 서브세트의 할당이 이루어진다. 셀에서 발생되는 호출은 먼제 셀에 의해 결정되는 순서로 그 셀의 기지국에 할당된 채널에 할당된다. 일단 할당된 채널이 통화중 상태에 있다면, 셀은 규정된 순서로, 인접한 셀의 기지국에 할당된 채널로부터 차용을 시도한다. 상기 차용하는 셀은 부가적인 채널을 차용하도록 특정 셀로 복귀하기 이전에 각 인접한 셀로부터 규정된 채널수를 차용한다. 인접한 셀로부터 차용된 채널은 소유자 셀에 의해 액세스되는 순서에 대해 실질적으로 역순으로 액세스된다. 이러한 것은 각 셀에 대해 전체 채널 세트가 그 셀에서 발생하는 호출에 의해 액세스되는 사전 정의된 순서를 명시하고 있다.
