Abstract: With the analysis on the frameworks of the paging channel of CDMA，this paper computes the ratio of all messages of paging channels, and educes the relation between paging load with BHCA. Having estimated the paging load of Zhengzhou, it puts forward a solution of in zone paging and reduces the paging load from 65 percent to 50 percent or so.

Key words: CDMA wireless network optimization, paging load, busy hour call attempt(BHCA)

摘要： 研究了CDMA寻呼信道的结构，计算了各种消息的寻呼信道占用率，得出了寻呼负荷和忙时用户呼叫尝试次数（BHCA）之间的函数关系。在对郑州的CDMA网络寻呼负荷估算之后，提出了分区域寻呼的解决方案，将系统的寻呼负荷由峰值的65％降低到峰值的
50％左右。
