Abstract

셀룰러 무선 통신 시스템에서 셀 싸이트의 섹터화된 안테나 또는 전체-방향 안테나의 통신 채널부하를 분배하는 방법과 장치가 제공된다. 과부하걸린 섹터의 셀 싸이트(100)의 안테나(102) 빔폭을 좁히고 인접한 섹터의 셀 싸이트(100)의 안테나(104) 범폭을 넓힘으로서 채널 부하가 분배된다. 다른 실시예로, 과부하걸린 셀 싸이트(100)에 인접한 셀 싸이트(120)의 안테나(124)출력을 줄임으로서 채널부하가 분배된다. 양자택일적으로, 과부하 걸린 셀 싸이트(100)에 인접한 셀 싸이트(116)의 안테나(118)출력을 증가시키므로서 채널 부하가 분배된다. 채널부하 분배후에, 과부하 걸리고(100) 인접한 셀 싸이트(116,120)의 각 가입자 장치는 가입자 장치에 가장 잘 서비스할 수 있는 특별한 셀 싸이트로 인계된다.
