摘　　要：CDMA网络由于协议、触发机制等问题无法实现多业务嵌套,从而使CDMA网络用户无法申请如IVPN等新增值业务,降低了用户的个性化体验。而作为下一代核心网络IMS(IP多媒体子系统)在业务层面具有"灵活的业务触发和业务嵌套能力"等特性,可以通过将CDMA网络锚定至IMS的方式来解决CDMA网络的问题。通过对C网锚定方案进行分析,说明了其主被叫通信的方式,总结了业务运营中的关键问题,并提出了解决方案,结合现网实际的呼叫流程,对方案进行了详细的说明。Due to the protocol and trigger mechanism, CDMA could not realize multiple services nested, and the user could not apply for new value-added service such as IPVN, and this would reduce the user＇s personalized experience .IMS（IP Multimedia Subsystem）, as the core network of next generation, features flexible service trigger and services nested, could solve this problem by IMS centralized control of CDMA-domain services. Based on analysis of CDMA anchoring schemes, the key problems in business operation are summarized, and the solution schemes proposed. And in combination with actual call flow of the present network, these schemes are described in detail in this paper.
