摘要
参照话音业务不良小区的判定方法,并结合CDMA1X数据业务的特点,提出了一种1X数据业务不良小区的判定方法。该方法利用统计学分析,采用正态分布模型对“判决指标”的数值分布进行了数学分析,并结合指标的物理意义,对“准入条件”和“判决门限”作出了合理设置。该判决方法在现网1X数据性能分析和优化实践中得到了有力验证。
Referring to the judgment methods of GSM and CDMA 1X voice service problem cells, and taking account of the characteristics of CDMA 1X data service, we put forward one kind of judgment method for 1X data service problem cells. This method uses statistics and adopts gaussian distribution model to analyze the key performance index. Taking both mathematic and physical meanings into account, we make the reasonable setting to admission rule and determination threshold.This method has been successfully proved in the real network performance analysis and optimization practice.
