WCDMA是第三代移动通信系统中的一种主流无线接入技术。论文介绍了WCDMA网络中软切换的分类,分析了软切换的执行策略和其中的重要参数,用系统级仿真的研究方法探讨了软切换门限和软切换比例,软切换门限和掉话率、阻塞率之间的关系,最后得出合适的软切换增加门限应该在3db～6db,软切换删除门限在5db～8db,为实际应用中进行参数设置提供了参考。
WCDMA is a mainstream wireless access technology in the third generation mobile communication system. This paper introduces the classification of soft handover in WCDMA network, analyzes the implementation strategy of soft handover and its important parameters, discusses the soft handover threshold and soft handover ratio, soft handover threshold and dropped call rate, blocking rate The relationship between the end of the soft handover to get the appropriate increase threshold should be 3db ~ 6db, soft-switch to delete the threshold 5db ~ 8db, for practical application parameters provided a reference.
