Abstract: Over the latest few years, most of the major telephony and services providers have got their attention on the LTE/SAE solution, in the attempt of getting the most bandwidth and features at the least implementation and operating price. One of the major challenges that 3GPP, the creator of LTE/SAE architecture, has faced is the IMS integration with SAE. The latest standard version available at this moment on IMS integration and its security challenges is TS 33.203, which is focused on 3G security aspects. When talking about IMS-SIP security, there are several studies that propose end-to-end security for a SIP conversation over EPS infrastructure. This paper reviews the security issues that resides in the SAE-IMS interaction and, looking at the specificities of the SIP conferencing, proposes a security model that uses GDOI management to secure the SIP conference data over IMS and SAE. One important aspect of conferencing in the mobile world is to realize the user is !
never stationary. One chapter of this paper describes the most complicated type of mobility scenario and also introduces the role of the Diameter server into this architecture.
