摘　　要：随着现阶段码分多址(CDMA)网络业务的大力发展,软交换架构的综合关口局被大量采用。其具有CDMA网络寻址功能,所以组网方面更加复杂。根据CDMA综合关口局进行系统组网的工程实践,在了解综合关口局整体组网的基础上,介绍了综合关口局的会话初始化协议(SIP)组网方案,分析了SIP组网应遵循的基本技术要求,提出了SIP组网的应用场景。通过现场大话务量测试,得出SIP组网情况下软交换关口局的话务负荷正常和设备性能稳定。研究结果为CDMA综合关口局SIP组网提供了参考依据。With rapid increasing of CDMAnetwork traffic, the is widely adopted. For its being of network addressing ability, softswitch integrated gateway the networking becomes more complicated. Based on project practice of network planning for CDMA integrated gateway and on the understanding of overall networking, the SIP networking mode is described, meanwhile the basic technical requirements for SIP networking mode are analyzed, the different application situations for SIP networking mode proposed. The large-scale traffic tests indicate that the network traffic load of the softswitch gateway in SIP networking mode is in normal condition and the equipment is stable in performance, thus providing certain reference for the SIP networking of CDMA integrated gateway.
