CDMA cellular networks are very promising to provide more capacity than AMPS system. However, heterogeneous traffic loading will cause the traffic congestion in hot-spot with CDMA system. In this paper, the tilted antenna mechanism for sectored cells in CDMA cellular networks is provided to relief the congestion in hot-spot sector. The proposed mechanism which tilts hot-spot antenna can meet the blocking probability of hot-spot sectors and its adjacent sectors below 1%. Besides the congestion relief for hot-spot, another benefit is the traffic balancing effect with tilted antenna mechanism that will reduce the transceivers of hot-spot basestation so we don't have to provide more extra facilities for hot-spot than for normal or light traffic sector.
