基于IMS的CCF计费功能方案

Design and Implementation of IMS-based CCF Charging Function

IMS是实现全方位网络融合的最佳选择。本文通过引入高可用性集群技术设计了IMS中的离线计费模式——计费采集功能(CCF)的主从热备份体系结构,并使用浮动IP技术和错误恢复技术为IMS中的离线计费问题提供较好的解决方案。这种主从热备份计费解决方案减少了运营成本,具有强大的处理能力,达到电信级性能。

IMS is one of the best choices for network convergence. Based on the techniques of high availability cluster, the active-standby architecture of the offiine charging mode CCF in IMS is designed. Meanwhile, the floating IP technique and the error recovery technique provide better solution for the offiine charging mode in IMS. The active-standby charging solution reduces the business cost, has the powerful processing capability and reaches the reliability of the telecommunications class.
