传统电信系统中非法窃听、业务盗用、计费欺骗等常见业务安全问题在IMS系统中仍然存在,针对目前IMS系统在安全防护方面的需求,研究提出了一种具有集成、融合、兼容等特征的IMS系统的安全防护框架,以解决标准IMS通信系统通常采用叠加式安全防护手段存在的效率、可用性等问题。并从IMS系统的用户接入安全、业务控制实体安全、端到端用户媒体流的安全等多方面介绍了一体化安全防护框架的实现初步设想,为IMS通信系统的安全防护提供了一种新的技术途径。
In the traditional telecommunication system, the common security problems such as illegal eavesdropping, service theft, billing cheating and other common business security still exist in the IMS system. In view of the current security requirements of the IMS system, this paper proposes an integrated, converged and compatible IMS system security framework to solve the standard IMS communication system usually adopts the superposition of safety protection means the existence of efficiency, availability and other issues. And introduced the implementation of integrated security framework from the aspects of user access security of IMS system, security of service control entity and end-to-end user media stream, which provided a new idea for the security protection of IMS communication system Technical approach.
