Abstract

본 발명은 핸드오프 예약이 가능한 CDMA 무선채널 할당방법에 관한 것이다. 종래기술은 가변하는 링크 용량하에서 핸드오프 전용채널을 예약하는 것이 어려웠던 문제점이 있다. 따라서, 본 발명은 기지국에 의해 설정된 두가지의 전체 허용 간섭양에서 현재 수신되는 간섭양을 감산하여 두가지의 여유허용 신호세기를 분류하여 무선채널을 할당함으로써 전용채널을 예약할 수 있는 것이다.The present invention relates to a CDMA radio channel allocation method capable of handoff reservation. The prior art has a problem in that it is difficult to reserve a handoff dedicated channel under a varying link capacity. Therefore, the present invention is able to reserve a dedicated channel by allocating a wireless channel by classifying two allowable signal strengths by subtracting the currently received interference amount from the two total allowed interference amounts set by the base station.
