Towards a New Approach for Securing IMS Networks

IMS presents an innovation in the world of telecommunications by providing a concrete Control Platform; the platform enables the delivery of multimedia services with high QoS range and with a soft convergence from circuit-switched services to the switching packet world. The IMS can unify access to multiple technologies and equipment-based IP. Indeed, the heterogeneity of access and technology imposes a challenge or repercussion in QoS, mobility and security. The article focuses on the importance of security, and it proposes a conceptual analysis on existing standards. Finally we propose an approach that meets the needs of a network such as IMS. The study focuses the main interfaces of IMS and security around and inside network with a sensitive context.
