摘　　要：为实现码分多址(code division multiple access,CDMA)网络Abis接口的信令监测,分析了Abis接口协议栈,阐述了信令信道和业务信道上消息的透传方式,提出了Abis接口信令解码方案。基于Abis接口业务信道承载层3信令这一特性,给出了业务信道上识别信令数据的方法,同时采用遍历法完成信息元素的解码,以此实现消息在信令监测平台的回放,为设计详细呼叫记录(call detail record,CDR)合成、出表、统计等功能模块奠定基础。经现网测试,验证了该解码方案的正确性与可行性,有效解决了CDMA网络Abis接口不同信道上各类消息的解码。In order to realize signaling monitoring of Abis interface in CDMA network,this paper studies Abis interface protocol stack,elaborates the transparent transmission of messages on signaling channel and traffic channel,presents decoding scheme on Abis interface in CDMA network.Based on Abis interface traffic channel bearing layer 3 signaling,using traversal method to achieve the decoding of the information elements and deduction distinguishes the signaling on traffic channels is proposed.Signaling has appeared in monitoring platform.This lays the foundation for designing function module about call detail record（CDR）synthesis,table and statistics.The accuracy and feasibility of this decoding plan has been validated by the real network testing,it effectively solves the signaling decoding on different channels.
