摘　　要：以CDMA2000网络A1接口BSAP(base station application part)协议监测关键技术研究与应用为切入点,以如何实现对CDMA2000网络进行实时、高效、可靠监测为研究重点。针对国内外现有网络协议监测技术协议解码、CDR合成研究方案时效性的不足,从协议解码算法流程设计、CDR(call data record)合成算法原理及算法效率(时间复杂度)来进行对比验证分析,并以此为突破口,设计了BSAP协议监测模块的实现方案。研究成果将可对同网络其他协议及接口监测方案提供参考,其研究和实现的内容可应用于网络监测系统、监测仪表中,能为现网的监测、运营商的运维提供可靠技术支撑。This paper gives a main conception on the key monitoring technology of BSAP protocol at A1 interface in CDMA2000 network. In order to get a better time efficiency of operation mechanism, the paper gives a focus on the protocol decoding process design algorithm, CDR synthesis algorithm and the related algorithm efficiency comparison （ time complexity）. The research result has an instructional meaning to other protocol analyzer in the familiar network monitor system, and it can be applied to the monitoring instrumentation and finally provides reliable technical support for operation and maintenance operators.
