随着IP多媒体子系统(IMS,IP Multimedia Subsystem)技术的发展和应用,其安全性越来越受到人们的重视,研究IMS的标准组织也从IMS的各个层面对其安全性进行了研究,并制定了相应的标准,如何将这些理论成果有效的组织应用起来则成为当前研究的重点。为此针对如何使用IMS业务控制层来支撑实现业务媒体流的安全问题提出了一种集成式安全架构的解决方法,此安全架构不会破坏IMS的整体架构并且能兼容IMS网络中已有的呼叫控制类设备,可供在IMS安全规划设计和实施建设时参考。
With the development and application of IP Multimedia Subsystem (IMS) technologies, more and more people pay more attention to its security. The standards organizations that study IMS also study their security from all aspects of IMS The corresponding standards have been established, and how to apply the organizations that have effective theoretical achievements has become the focus of current research. To solve this problem, a solution to how to use the IMS service control layer to support the security of service media flows is proposed. The security architecture does not destroy the overall architecture of the IMS and is compatible with the existing calls in the IMS network Control equipment, for reference in the design and implementation of IMS security planning.
