摘　　要：增值业务的产生,丰富了通信网络,同时也增加了网络负荷。为保证通信质量,对增值业务关键接口进行监测的研究显得尤为重要。以CDMA2000网络作为承载网络,以增值业务网络中的下载业务系统作为切入点,对该系统与WAP网关相连接口下的Download协议进行监测研究;通过构造合理的哈希函数优化了CDR(calling detail record)合成处理速度。将此方法推广至增值业务中的其他关键接口,通过现网数据测试,运行效果良好。The generation of VAS （Value-Added Services） enriches the communication network, but it also leads to the heavy network load. In order to ensure the quality of communication, it＇ s particularly important to study the monitoring of VAS critical interfaces. Based on CDMA2000 network, and taken the download business system in VAS as a study point, this paper studies the monitoring of Download protocol between the WAP gateway and the download business system inter- face. A reasonable hash function is proposed to optimize the CDR （ Calling Detail Record） synthesis processing speed. This method is extended to the other important interfaces of VAS and the feasibility is verified.
