EV-DO监测系统中R-P接口业务信令追踪的研究与实现

摘要

In EV-DO network,the signaling monitoring system is particularly important to the analyses of users data business operation.Ai-ming at CDR synthesis of A1 1 signaling and PPP signaling between R-P interface which is an important interface in EV-DO network,and com-bining the service characteristics of calling and paging procedures,this paper presents a series of optimisation and improvement schemes.By testing on ED-VO existing network data and its corresponding experimental result derived,it is shown that the optimisation of the correlation mechanism between signaling and service data messages shortens the tracing statistic time in regard to the signaling of data network paging and user calling businesses to the highest of 30 s,the refinement in indexes boosts fault positioning accuracy as well.This improved scheme has important significance for optimising the analyses platform of networks operation and maintenance.%在EV-DO网络中，信令监测系统对于用户数据业务运营的分析尤为重要。针对EV-DO网络中的重要数据接口R-P接口间A11及PPP信令CDR（Call Data Record）的合成，结合主叫和寻呼过程的业务特征，提出一系列优化及改进方案。经过EV-DO现网数据的测试以及产生的相应实验结果表明，优化信令与业务数据消息间的关联机制，缩短了数据网络寻呼与用户主叫业务信令的追踪统计时间最高可达30 s，指标的细化提升了故障定位准确性。这项改进方案对于优化网络运维的分析平台有着重要意义。
