IMS网络AGCF异地容灾机制

AGCF Remote Disaster Recovery Mechanism of IMS Network

随着IP多媒体子系统(IMS)网络商用部署步伐的逐步加快,IMS网络的高效可靠组网方案成为运营商的关注焦点。AGCF作为IMS网络重要的接入控制设备,其安全可靠的运行将影响IMS业务的稳定使用。对目前IMS网络AGCF异地容灾机制进行了深入研究,提出了一种AGCF异地容灾机制,解决了异地容灾机制的倒换流程和倒回流程,有效增强了系统的容灾性,大大缩短了IMS系统的平均故障间隔时间。

With the rapid commercial deployment of IP Multimedia Subsystem（IMS） network, the operators pay more attention to the high-efficiency and reliable networking solution of IMS network. The AGCF is an important access control device of IMS network,and its safe and reliable operation may affect the stable use of IMS services. This paper studies in depth the AGCF remote disaster recovery mechanism of current IMS network, and proposes an AGCF remote disaster recovery mechanism to implement the switching process and the backflow process of remote disaster recovery mechanism. This mechanism can effectively enhance the system disaster tolerance and greatly shorten the mean time between failures of the IMS system.
