IMS is the key technology to realize convergence of ground network. We apply IMS to satellite communication systems, put forward a set of convergence architecture,and achieve interoperability of users between ground network and satellite communication systems. It implements the user multi-access methods and ensures the service quality of communication for users via a uniform session management and resource allocation. We use OPNET simulation software to build TDMA satellite model and implement the core functions of IMS by embedded Linux system. Finally, this paper validates feasibility of convergence system and rationality of resource allocation mechanisms by the-loop simulation system. The simulation results show that the proposed convergence architecture is basically feasible and the given resource allocation mechanism is more reasonable,which meet the basic needs of users.
